The contents of these patent applications are incorporated herein in their entirety by reference. TECHNICAL FIELD OF THE INVENTION [00021 This invention relates to the field of cancer vaccines. In particular, the application relates to a carbohydrate-based vaccine containing the B cell epitope, Globo H, which is conjugated to the immunogenic carrier DT-CRM 197. More particularly, the invention is directed at anti-cancer Globo H-DT vaccines administered with novel glycolipid adjuvants, such as C34. BACKGROUND OF THE INVENTION 100031 To design therapy against cancer, it is desirable to seek molecular targets of cancer or cancer stem cells that are absent from normal cells. Aberrant glycosylation is often associated with tumor progression and was first described by Meezan et al. in 1969 with the demonstration that cancer glycans differ from healthy cells. (Meezan E, et al. (1969) Biochemistry 8:2518-2524.) Aberrant glycosylations include loss or over-expression of certain structures, the persistence of truncated structures and the emergence of novel structures. The structural differences were later supported by many histological evidences using lectin-staining compared with healthy and malignant tissue.(Tumer GA (1992) Clin Chim Acta 208:149-171; Gabius HJ (2000) Naturwissenschaften 87:108-121.) 100041 More recently, tumor associated carbohydrate antigens were identified by monoclonal antibodies and mass spectrometry.(Shriver Z, et al. (2004) Mat Rev Drug Disc 3:863-873; Pacino G, et al. (1991) Br J Cancer 63:390-398.) To date, numerous tumor WO 2010/005598 PCT/US2009/004519 associated antigens expressed on cancer cells in the form of glycolipids or glycoproteins have been characterized and correlated to certain types of cancers. (Bertozzi CR, Dube DH (2005) Nat Rev Drug Discovery 4:477-488.) Although relatively little is known about the role of surface carbohydrates play in malignant cells, passively administered or vaccine induced antibodies against these antigens have correlated with improved prognosis. [00051 Of the tumor associated glycans reported, the glycolipid antigen Globo H (Fuca -+2 Galpl-+3 GalNAcpl-+3 Galal-+4 Galpl-4 Glc) was first isolated and identified in 1984 by Hakomori et al. from breast cancer MCF-7 cells. (Bremer EG, et al. (1984) JBiol Chem 259:14773-14777.) Further studies with anti-Globo H monoclonal antibodies showed that Globo H was present on many other cancers, including prostate, gastric, pancreatic, lung, ovarian and colon cancers and only minimal expression on luminal surface of normal secretory tissue which is not readily accessible to immune system. (Ragupathi G, et al. (1997) Angew Chem Int Ed 36:125-128.) In addition, it has been established that the serum of breast cancer patient contains high level of anti-Globo H antibody. (Gilewski T el al. (2001) Proc Natl Acad Sci USA 98:3270-3275; Huang C-Y, et aL. (2006) Proc Natl Acad Sci USA 103:15-20; Wang C-C, et al. (2008) Proc Nall Acad Sci USA 105(33):11661-11666) and patients with Globo H-positive tumors showed a shorter survival in comparison to patients with Globo H-negative tumors. (Chang, Y-J, et al. (2007) Proc Natl Acad Sci USA 104(25):10299-10304.) These findings render Globo H, a hexasaccharide epitope, an attractive tumor marker and a feasible target for cancer vaccine development. 10006] Globo H is a cancer antigen overly expressed in various epithelial cancers. It has been suggested that this antigen can serve as a target in cancer immunotherapy. While vaccines have been developed to elicit antibody responses against Globo H, their anti-cancer efficacies are unsatisfactory due to low antigenicity of Globo H. There is a need for a new vaccine capable of eliciting high levels of immune responses targeting Globo H. [00071 Stem cells are defined as a group of cells with the capacity for self-renewal and for differentiation into different types of cells and tissues. (Reya T et al., (2001) Nature 414:105 111.) As both malignant tumors and normal tissues contain heterogeneous populations of cells, cancer stem cells might play a key role in tumor growth and maintaining tumor heterogeneity. Cancer stem cells have been identified from a variety of solid tumors, such as brain, breast, colon, and prostate cancers. Breast cancer stem cells (BCSCs) were first shown 2 WO 2010/005598 PCT/US2009/004519 to reside in the CD24^CD44' subpopulation of breast cancer by Al-Hajj et al., based on their ability to generate tumors with phenotypic diversity on xenotransplantation into NOD/SCID mice (Al-Hajj M, et al., (2003) Proc Nall Acad Sci USA 100:3983-3988). The majority of early disseminated cancer cells in the bone marrow of breast cancer patients displayed the phenotype of CD24'CD44+ (Balic M et al., (2006) Clin Cancer Res 12:5615-5621), suggesting that BCSCs were capable of metastasis. Based on their capability for growth, differentiation, and metastasis and their resistance to radiation, BCSCs are a major target for therapy of breast cancer (Tang C. et al., (2007) FASEB J 21:1-9). [00081 In breast cancer, Globo H expression was observed in >60% of ductal, lobular, and tubular carcinoma, but not in nonepithelial breast tumors (Mariani-Constantini R et al., (1984) Am. J. Pathol, 115:47-56). Globo H is not expressed in normal tissue except for weak expression in the apical epithelial cells at lumen borders, a site that appears to be inaccessible to the immune system (Id.; Zhang S. et al., (1997) Int. J. Cancer 73:42-49). [00091 Globo H also is expressed in breast cancer stem cells (BCSCs). Flow cytometry revealed Globo H is expressed in 25/41 breast cancer specimens (61.0%). Non-BCSCs from 25/25 and BCSCs from 8/40 (20%) express Globo H. The stage-specific embryonic antigen 3 (SSEA-3), the pentasaccharide precursor of Globo H, is expressed in 31/40 (77.5%) tumors. Non-BCSCs from 29/31 and BCSCs from 25/40 (62.5%) expressed SSEA-3. (Chang W-W. et al., (2008) Proc Natl AcadSci USA 105(33):11667-11672.) 100101 Danishefsky and Livingston previously reported the preparation of Globo H-KLH vaccine (Gilewski T el al. (2001) Proc Natl Acad Sci USA 98:3270-3275; Ragupathi G, et al. (1997) Angew Chem Int Ed 36:125-128; Kudryashov V, et al. (1998) GlycoconjJ. 15:243 249; Slovin SF et al (1997) Proc Natl Acad Sci USA 96:5710-5715) and the heptavalent vaccine (containing GM2, Globo H, Lewis Y, Tn, STn, TF, and Tn-MUC I individually conjugated to KLH; Sabbatini PJ et al (2007) Clin Cancer Res 13:4170-4177) against a variety of cancers. However, patients immunized with the heptavalent vaccine induced antibody responses against only five of the seven antigens except GM2 and Lewis Y antibodies. Rather than ubiquitously expressed antigen such as GM2, Globo H exceptionally expressed on tumor cells with only minimal level on normal secretory tissue makes it a desirable target for vaccine development. In their studies, ozonolysis of Globo H aglycone was followed by reductive anination with KLH carrier protein to generate about 150 3 927 0390AUPR carbohydrate units per protein.( Ragupathi G, et a. (1997) Angew Chem In; Ed 36:125-128.) Further refinement increased the carbohydrate conjugation ratio to about 720:1 by using MMCCH linker. (Wang S-K, et al, (2008). Proc NadAcad Sci USA 105:3690-3695,) However, it was difficult to precisely characterize the glycoconjugate. In addition, the synthetic vaccine in combination with the immunological adjuvant QS-21 was shown to induce mainly IgM and to a lesser extent lgC antibodies in both prostate and nietastatic breast cancer patients, In the phase I clinical trial, the vaccine also showed minimal toxicity with transient local skin reactions at the vaccination site. (Cilewski T elal. (2001) Proc Nat/ Acad Sei USA 98:3270-3275: Ragupathi 3, et at (1997) Angcw Chem ha Ed 36:125-128; Slovin SF et al (1997) Proc Nar Acad Sci USA 96:5710-5715.) Mild flu-like symptoms which have been observed in some of the patients were probably associated with the side effect of QS-2 I. A pentavalent vaccine containing five prostate and breast cancer associated carbohydrate antigens -- Globo-H, GM2, STn, TF and Tn -- conjugated to naleimide-modified carrier protein KL-H has been reported to produce anti-obo H sera with higher tigers of Igo than IgM in ELISA assays, (Zhu J. et al. (2009) J. Am Chem Soc. 13 1(26):9298-9303). fN1011) Therefore, it is desirable to identify an alternative carrier and adjuvant to augment the antibody response to Globo H. especially with high titer of IgG, and to improve the vaccine efficacy with minimal side effects, [0011A] It is an object of the invention to provide an immunogenic composition, and/or the use of an immunogenic composition, and/or a method of treatment, and/or a vaccine which overcomes or ameliorates at least one disadvantage of known compositions, uses, methods and/or vaccines or to at least provide the public with a useful choice.

DETAILED DESCRIPTION OF THE INVENTION [00511 The present invention relates to the surprising finding that-DT-CRM197 is a promising carrier protein for Globo -1 and SSEA-4 not only because it has been widely used for human vaccination against diphtheria for decades, but also because of its highly immunogenic property. Most importantly, it has been approved by the FDA for various glycoconjugate vaccines. Diphtheria toxin cross-reacting material 197 (DT-CRM 197) is a nontoxic mutant (G52E) of DT that shares the immunological properties of the native molecule and its ability to bind to heparin-binding epidermal growth factor (HB-EGF), the specific cell-membrane receptor for DT that is often overexpressed in cancer. (Buzzi S. et al., Cancer Immunology, Immunotherapy (2004), 53(1l):1041-1048). 100521 Using C34 as adjuvant, both GH-DT and SSEA-4-DT showed the most effective immune response to induce more IgG than IgM antibodies against tumor antigens. The GH DT in combination with C34 induced antibodies which not only neutralize Globo H but also 10 WO 2010/005598 PCT/US2009/004519 SSEA-3 (Gb5) and SSEA-4, which all are specific for breast cancer cells and the cancer stem cells. [00531 Further, the disclosed glycan microarray offers a powerful platform for antibody specificity test and is useful for identification of patients for the vaccine trial and for the monitoring of their immune response after immunization.

25 0 OH 100621 The a-GalCer analogs of the present disclosure include a-GalCer analogs of bacterial origin (Group 1: C2, C3 and Cl 4), a-GalCer analogs modified with sulfonation (Group II: C4, C5 and C9), phenyl-alkyl chain a-GalCer analogs (Group III: C6-C8, C10 C11, C15-C16, C18-C34, C8-5 and C8-6) and phytosphingosine truncated a-GalCer analogs (Group IV: C12, C13 and C17). The structures of C34 and other alpha-galactosyl ceramide analogs and their use as adjuvants are disclosed in detail in PCT patent Application No. PCT/US2008/060275 filed April 14, 2008. [0063] The synthetic a-GalCer analogs, including C34, are capable of forming complexes with a CDId molecule. Synthetic a-GalCer analogs are capable of being recognized by NKTs T-cell receptors. Synthetic a-GalCer analogs are capable of eliciting a THI-type, a TH2-type or a TH I-type and a TH2-type response. The a-GalCer analogs are capable of activating NKTs in vitro. a-GalCer analogs are capable of activating NKTs in vivo. [0064] As used herein, the term "glycan" refers to a polysaccharide, or oligosaccharide. Glycan is also used herein to refer to the carbohydrate portion of a glycoconjugate, such as a glycoprotein, glycolipid, glycopeptide, glycoproteome, peptidoglycan, lipopolysaccharide or a proteoglycan. Glycans usually consist solely of O-glycosidic linkages between monosaccharides. For example, cellulose is a glycan (or more specifically a glucan) composed of B-1,4-linked D-glucose, and chitin is a glycan composed of 3-1,4-l inked N acetyl-D-glucosamine. Glycans can be homo or heteropolymers of monosaccharide residues, and can be linear or branched. Glycans can be found attached to proteins as in glycoproteins and proteoglycans. They are generally found on the exterior surface of cells. 0- and N-linked glycans are very common in eukaryotes but may also be found, although less commonly, in prokaryotes. N-Linked glycans are found attached to the R-group nitrogen (N) of asparagine in the sequon. The sequon is a Asn-X-Ser or Asn-X-Thr sequence, where X is any amino acid except praline. 13 WO 2010/005598 PCT/US2009/004519 100651 As used herein, the term "glycoprotein" refers to a protein covalently modified with glycan(s). There are four types of glycoproteins: 1) N-linked glycoproteins, 2) O-linked glycoproteins (mucins), 3) glucosaminoglycans (GAGs, which are also called proteoglycans), 4) GPI-anchored. Most glycoproteins have structural micro-heterogeneity (multiple different glycan structures attached within the same glycosylation site), and structural macro heterogeneity (multiple sites and types of glycan attachment). 100661 As used herein, the term "antigen" is defined as any substance capable of eliciting an immune response. [00671 As used herein, the term "immunogen" refers to an antigen or a substance capable of inducing production of an antigen, such as a DNA vaccine. 100681 As used herein, the term "immunogenicity" refers to the ability of an immunogen, antigen, or vaccine to stimulate an immune response. [00691 As used herein, the term "immunotherapy" refers to an array of treatment strategies based upon the concept of modulating the immune system to achieve a prophylactic and/or therapeutic goal. 100701 As used herein, the term "CDld" refers to a member of the CDI (cluster of differentiation 1) family of glycoproteins expressed on the surface of various human antigen presenting cells. CDId presented lipid antigens activate natural killer T cells. CDId has a deep antigen-binding groove into which glycolipid antigens bind. CDI d molecules expressed on dendritic cells can bind and present glycolipids, including a-GalCer analogs such as C34. [00711 As used herein, the term "adaptive immune system" refers to highly specialized, systemic cells and processes that eliminate pathogenic challenges. The cells of the adaptive immune system are a type of leukocyte, called a lymphocyte. B cells and T cells are the major types of lymphocytes. [00721 As used herein, the term "T cells" and "Ts" refer to a group of white blood cells known as lymphocytes, that play a central role in cell-mediated immunity. T cells can be distinguished from other lymphocyte types, such as B cells and NKs by the presence of a special receptor on their cell surface called the T cell receptor (TCR). Several different subsets of T cells have been described, each with a distinct function. Helper T (TH) Cells are 14 WO 2010/005598 PCT/US2009/004519 the "middlemen" of the adaptive immune system. Once activated, they divide rapidly and secrete small proteins called cytokines that regulate or "help" the immune response. Depending on the cytokine signals received, these cells differentiate into TH 1, Tj2, TH 17, or one of other subsets, which secrete different cytokines. 100731 As used herein, the term "antigen-presenting cell" (APC) refers to a cell that displays foreign antigen complexed with major histocompatibility complex (MHC) on its surface. T-cells may recognize this complex using their TCR. APCs fall into two categories: professional or non-professional. Dendritic cells (DCs) fall under the professional category and are capable of presenting antigen to T cells, in the context of CDI. In an exemplary implementation, the DCs utilized in the methods of this disclosure may be of any of several DC subsets, which differentiate from, in one implementation, lymphoid or, in another implementation, myeloid bone marrow progenitors. 100741 As used herein, the term "naive cell" refers to an undifferentiated immune system cell, for example a CD4 T-cell, that has not yet specialized to recognize a specific pathogen. 100751 As used herein, the term "natural killer cells" and "NKs" refers to a class of lymphoid cells which are activated by interferons to contribute to innate host defense against viruses and other intracellular pathogens. [00761 As used herein, the term "natural killer T cells" (NKTs) refers to a subset of T cells that share characteristics/receptors with both conventional Ts and NKs. Many of these cells recognize the non-polymorphic CDI d molecule, an antigen presenting molecule that binds self- and foreign lipids and glycolipids. The TCR of the NKTs are able to recognize glycolipid antigens presented (chaperoned) by a CDId molecule. A major response of NKTs is rapid secretion of cytokines, including IL-4, IFN-y and IL- 10 after stimulation and thus influence diverse immune responses and pathogenic processes. The NKTs may be a homogenous population or a heterogeneous population. In one exemplary implementation, the population may be "non-invariant NKTs", which may comprise human and mouse bone marrow and human liver T cell populations that are, for example, CDId-reactive non invariant T cells which express diverse TCRs, and which can also produce a large amount of IL- 4 and IFN-y. The best known subset of CDld-dependent NKTs expresses an invariant TCR-alpha (TCR-a) chain. These are referred to as type I or invariant NKTs (iNKTs). These 15 WO 2010/005598 PCT/US2009/004519 cells are conserved between humans (Va24i NKTs) and mice (Val4i NKTs) and are implicated in many immunological processes. [00771 As used herein, the term "cytokine" refers to any of numerous small, secreted proteins that regulate the intensity and duration of the immune response by affecting immune cells differentiation process usually involving changes in gene expression by which a precursor cell becomes a distinct specialized cell type. Cytokines have been variously named as lymphokines, interleukins, and chemokines, based on their presumed function, cell of secretion, or target of action. For example, some common interleukins include, but are not limited to, IL-12, IL-18, IL-2, IFN- y, TNF, IL-4, IL-10, IL-13, IL-21 and TGF-B. 100781 As used herein, the term "chemokine" refers to any of various small chemotactic cytokines released at the site of infection that provide a means for mobilization and activation of lymphocytes. Chemokines attract leukocytes to infection sites. Chemokines have conserved cysteine residues that allow them to be assigned to four groups. The groups, with representative chemokines, are C-C chemokines (RANTES, MCP- 1, MIP- I a, and MIP- 11), C-X-C chemokines (IL-8), C chemokines (Lymphotactin), and CXXC chemokines (Fractalkine). [00791 As used herein, the term "TH2-type response" refers to a pattern of cytokine expression such that certain types of cytokines, interferons, chemokines are produced. Typical TH2 cytokines include, but are not limited to, IL-4, IL-5, IL-6 and IL-10. [00801 As used herein, the term "THl -type response" refers to a pattern of cytokine expression such that certain types of cytokines, interferons, chemokines are produced. Typical THI cytokines include, but are not limited to, IL-2, IFN-y, GMCSF and TNF-B. 100811 As used herein, the term "Tti biased" refers to am immunogenic response in which production of Til cytokines and/or chernokines is increased to a greater extent than production of TH2 cytokines and/or chemokines. 100821 As used herein, the term "epitope" is defined as the parts of an antigen molecule which contact the antigen binding site of an antibody or a T cell receptor. [00831 As used herein, the term "vaccine" refers to a preparation that contains an antigen, consisting of whole disease-causing organisms (killed or weakened) or components of such 16 WO 2010/005598 PCT/US2009/004519 organisms, such as proteins, peptides, or polysaccharides, that is used to confer immunity against the disease that the organisms cause. Vaccine preparations can be natural, synthetic or derived by recombinant DNA technology. 100841 As used herein, the term "immunologic adjuvant" refers to a substance used in conjunction with an immunogen which enhances or modifies the immune response to the immunogen. The a-GalCer analogs of the present disclosure are used as immunologic adjuvants to modify or augment the effects of a vaccine by stimulating the immune system of a patient who is administered the vaccine to respond to the vaccine more vigorously. In an exemplary implementation, the analog C34 is used as an adjuvant. [00851 As used herein, the term "alum adjuvant" refers to an aluminum salt with immune adjuvant activity. This agent adsorbs and precipitates protein antigens in solution; the resulting precipitate improves vaccine immunogenicity by facilitating the slow release of antigen from the vaccine depot formed at the site of inoculation. [00861 As used herein, the term "anti-tumor immunotherapy active agent" refers to antibody generated by a vaccine of the of the present disclosure that inhibits, reduces and/or eliminates tumors. 100871 As used herein, the term "antigen specific" refers to a property of a cell population such that supply of a particular antigen, or a fragment of the antigen, results in specific cell proliferation. [00881 As used herein, the term "Flow cytometry" or "FACS" means a technique for examining the physical and chemical properties of particles or cells suspended in a stream of fluid, through optical and electronic detection devices. 100891 Amino acid residues in peptides shall hereinafter be abbreviated as follows: Phenylalanine is Phe or F; Leucine is Leu or L; Isoleucine is Ile or I; Methionine is Met or M; Valine is Val or V; Serine is Ser or S; Proline is Pro or P; Threonine is Thr or T; Alanine is Ala or A; Tyrosine is Tyr or Y; Histidine is His or H; Glutamine is Gln or Q; Asparagine is Asn or N; Lysine is Lys or K; Aspartic Acid is Asp or D; Glutamic Acid is Glu or E; Cysteine is Cys or C; Tryptophan is Trp or W; Arginine is Arg or R; and Glycine is Gly or G.

Freeman & Co., New York 1983. 17 WO 2010/005598 PCT/US2009/004519 100901 The compositions disclosed herein can be included in a pharmaceutical or nutraceutical composition together with additional active agents, carriers, vehicles, excipients, or auxiliary agents identifiable by a person skilled in the art upon reading of the present disclosure. 100911 The pharmaceutical or nutraceutical compositions preferably comprise at least one pharmaceutically acceptable carrier. In such pharmaceutical compositions, the compositions disclosed herein form the "active compound," also referred to as the "active agent." As used herein the language "pharmaceutically acceptable carrier" includes solvents, dispersion media, coatings, antibacterial and antifungal agents, isotonic and absorption delaying agents, and the like, compatible with pharmaceutical administration. Supplementary active compounds can also be incorporated into the compositions. A pharmaceutical composition is formulated to be compatible with its intended route of administration. Examples of routes of administration include parenteral, e.g., intravenous, intradermal, subcutaneous, oral (e.g., inhalation), transdermal (topical), transmucosal, and rectal administration. Solutions or suspensions used for parenteral, intradermal, or subcutaneous application can include the following components: a sterile diluent such as water for injection, saline solution, fixed oils, polyethylene glycols, glycerine, propylene glycol, or other synthetic solvents; antibacterial agents such as benzyl alcohol or methyl parabens; antioxidants such as ascorbic acid or sodium bisulfite; chelating agents such as ethylenediaminetetraacetic acid; buffers such as acetates, citrates, or phosphates and agents for the adjustment of tonicity such as sodium chloride or dextrose. pH can be adjusted with acids or bases, such as hydrochloric acid or sodium hydroxide. The parenteral preparation can be enclosed in ampoules, disposable syringes, or multiple dose vials made of glass or plastic. [00921 Subject as used herein refers to humans and non-human primates (e.g., guerilla, macaque, marmoset), livestock animals (e.g., sheep, cow, horse, donkey, and pig), companion animals (e.g., dog, cat), laboratory test animals (e.g., mouse, rabbit, rat, guinea pig, hamster), captive wild animals (e.g., fox, deer), and any other organisms who can benefit from the agents of the present disclosure. There is no limitation on the type of animal that could benefit from the presently described agents. A subject regardless of whether it is a human or non human organism may be referred to as a patient, individual, animal, host, or recipient. 18 WO 2010/005598 PCT/US2009/004519 100931 Pharmaceutical compositions suitable for an injectable use include sterile aqueous solutions (where water soluble) or dispersions and sterile powders for the extemporaneous preparation of sterile injectable solutions or dispersion. For intravenous administration, suitable carriers include physiological saline, bacteriostatic water, Cremophor ELTM (BASF, Parsippany, NJ.), or phosphate buffered saline (PBS). In all cases, the composition should be sterile and should be fluid to the extent that easy syringability exists. It should be stable under the conditions of manufacture and storage and be preserved against the contaminating action of microorganisms such as bacteria and fungi. The carrier can be a solvent or dispersion medium containing, for example, water, ethanol, polyol (for example, glycerol, propylene glycol, and liquid polyetheylene glycol, and the like), and suitable mixtures thereof. The proper fluidity can be maintained, for example, by the use of a coating such as lecithin, by the maintenance of the required particle size in the case of dispersion and by the use of surfactants. Prevention of the action of microorganisms can be achieved by various antibacterial and antifungal agents, for example, parabens, chlorobutanol, phenol, ascorbic acid, thimerosal, and the like. In many cases, it will be preferable to include isotonic agents, for example, sugars, polyalcohols such as manitol, sorbitol, or sodium chloride in the composition. Prolonged absorption of the injectable compositions can be brought about by including in the composition an agent which delays absorption, for example, aluminum monostearate and gelatin. 100941 Sterile injectable solutions can be prepared by incorporating the active compound in the required amount in an appropriate solvent with one or a combination of ingredients enumerated above, as required, followed by filtered sterilization. Generally, dispersions are prepared by incorporating the active compound into a sterile vehicle which contains a basic dispersion medium and the required other ingredients from those enumerated above. In the case of sterile powders for the preparation of sterile injectable solutions, methods of preparation include vacuum drying and freeze-drying, which yields a powder of the active ingredient plus any additional desired ingredient from a previously sterile-filtered solution thereof. [00951 Oral compositions generally include an inert diluent or an edible carrier. For the purpose of oral therapeutic administration, the active compound can be incorporated with excipients and used in the form of tablets, troches, or capsules, e.g., gelatin capsules. Oral 19 WO 2010/005598 PCT/US2009/004519 compositions can also be prepared using a fluid carrier for use as a mouthwash. Pharmaceutically compatible binding agents, or adjuvant materials can be included as part of the composition. The tablets, pills, capsules, troches and the like can contain any of the following ingredients, or compounds of a similar nature: a binder such as microcrystalline cellulose, gum tragacanth or gelatin; an excipient such as starch or lactose, a disintegrating agent such as alginic acid, Primogel, or corn starch; a lubricant such as magnesium stearate or sterotes; a glidant such as colloidal silicon dioxide; a sweetening agent such as sucrose or saccharin; or a flavoring agent such as peppermint, methyl salicylate, or orange flavoring. [00961 For administration by inhalation, the compounds are delivered in the form of an aerosol spray from pressured container or dispenser which contains a suitable propellant, e.g., a gas such as carbon dioxide, or a nebulizer. [0097] Systemic administration can also be transmucosal or transdermal. For transmucosal or transdermal administration, penetrants appropriate to the barrier to be permeated are used in the formulation. Such penetrants are generally known in the art, and include, for example, for transmucosal administration, detergents, bile salts, and fusidic acid derivatives. Transmucosal administration may be accomplished through the use of nasal sprays or suppositories. For transdermal administration, the active compounds are formulated into ointments, salves, gels, or creams as generally known in the art. The compounds can also be prepared in the form of suppositories (e.g., with conventional suppository bases such as cocoa butter and other glycerides) or retention enemas for rectal delivery. [00981 According to implementations, the active compounds are prepared with carriers that will protect the compound against rapid elimination from the body, such as a controlled release formulation, including implants and microencapsulated delivery systems. Biodegradable, biocompatible polymers can be used, such as ethylene vinyl acetate, polyanhydrides, polyglycolic acid, collagen, polyorthoesters, and polylactic acid. Methods for preparation of such formulations will be apparent to those skilled in the art. The materials can also be obtained commercially from Alza Corporation and Nova Pharmaceuticals, Inc. Liposomal suspensions (including liposomes targeted to infected cells with monoclonal antibodies to cell-specific antigens) can also be used as pharmaceutically acceptable carriers. These can be prepared according to methods known to those skilled in the art, for example, as described in U.S. Pat. No. 4,522,811, which is incorporated by reference herein. 20 WO 2010/005598 PCT/US2009/004519 [00991 It is advantageous to formulate oral or parenteral compositions in dosage unit form for ease of administration and uniformity of dosage. Dosage unit form as used herein refers to physically discrete units suited as unitary dosages for the subject to be treated; each unit containing a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the required pharmaceutical carrier. [01001 Toxicity and therapeutic efficacy of such compounds may be determined by standard pharmaceutical procedures in cell cultures or experimental animals, e.g., for determining the

LD

50 (the dose lethal to 50% of the population) and the ED 50 (the dose therapeutically effective in 50% of the population). The dose ratio between toxic and therapeutic effects is the therapeutic index and it can be expressed as the ratio LD 50 /EDso. Compounds which exhibit ' high therapeutic indices are preferred. While compounds that exhibit toxic side effects can be used, care should be taken to design a delivery system that targets such compounds to the site of affected location to minimize potential damage to uninfected cells and, thereby, reduce side effects. [01011 The data obtained from the cell culture assays and animal studies can be used in formulating a range of dosage for use in humans. The dosage of such compounds lies preferably within a range of circulating concentrations that include the ED 50 with little or no toxicity. The dosage can vary within this range depending upon the dosage form employed and the route of administration utilized. For any compound used in the method of the disclosure, the therapeutically effective dose can be estimated initially from cell culture assays. A dose can be formulated in animal models to achieve a circulating plasma concentration range that includes the IC 50 (i.e., the concentration of the test compound which achieves a half-maximal inhibition of symptoms) as determined in cell culture. Such information can be used to more accurately determine useful doses in humans. Levels in plasma may be measured, for example, by high performance liquid chromatography. 101021 As defined herein, a therapeutically effective amount of the active compound (i.e., an effective dosage) may range from about 0.001 to 100 g/kg body weight, or other ranges that would be apparent and understood by artisans without undue experimentation. The skilled artisan will appreciate that certain factors can influence the dosage and timing required to effectively treat a subject, including but not limited to the severity of the disease or disorder, previous treatments, the general health or age of the subject, and other diseases present. 21 WO 2010/005598 PCT/US2009/004519 10103] According to another aspect, one or more kits of parts can be envision ned by the person skilled in the art, the kits of parts to perform at least one of the methods herein disclosed, the kit of parts comprising two or more compositions, the compositions comprising alone or in combination an effective amount of the compositions disclosed herein according to the at least one of the above mentioned methods. 101041 The kits possibly include also compositions comprising active agents, identifiers of a biological event, or other compounds identifiable by a person skilled upon reading of the present disclosure. The kit can also comprise at least one composition comprising an effective amount of the compositions disclosed herein or a cell line.

[01051 As used herein, the term "polypeptide" refers to any multimer or polymer of amino acid residues. A polypeptide may be composed of two or more polypeptide chains. A polypeptide includes a protein, a peptide, and an oligopeptide. A polypeptide can be linear or branched. A polypeptide can comprise modified amino acid residues, amino acid analogs or non-naturally occurring amino acid residues and can be interrupted by non-amino acid residues. Included within the definition are amino acid polymers that have been modified, whether naturally or by intervention, e.g., formation of a disulfide bond, glycosylation, lipidation, methylation, acetylation, phosphorylation, or by manipulation, such as conjugation with a labeling component. 101061 As used herein, the term "specifically binding," refers to the interaction between binding pairs (e.g., an antibody and an antigen). In various instances, specifically binding can be embodied by an affinity constant of about 10-6 moles/liter, about 1 0-7 moles/liter, or about 10- moles/liter, or less. Cancer Vaccines of the Invention 101071 One embodiment of this invention is a method of treating cancer by administering to a subject in need thereof an effective amount of an immune composition containing either Globo H or a fragment thereof (e.g., stage specific embryonic antigen-3 (SSEA-3, also known as Gb5), or SSEA-4) and an adjuvant.

"An effective amount" as used herein refers to the amount of each active agent required to confer therapeutic effect on the subject, either alone or in combination with one or more other active agents. Effective amounts vary, as recognized by those skilled in the art, depending on route of administration, excipient usage, and co-usage with other active agents. 10111] The immune composition used in the above-described method can contain a glycan (i.e., a molecule containing a sugar moiety) that is Globo H or a fragment thereof and an adjuvant. Globo H is a glycan containing the hexasaccharide epitope (Fuca1 -+2 Gals1 -+3 GalNAcp1l-+3 Galal-+4 Galpl1-+4 Glc), and optionally, a non-sugar moiety. Its fragment is a glycan containing a fragment of the hexasaccharide epitope and, if applicable, the non-sugar moiety. These oligosaccharides can be prepared by routine methods. (See Huang et al., Proc. Na. Acad. Sci. USA 103:15-20 (2006)). If desired, they can be linked to a non-sugar moiety. [0 1121 The parent application U.S. Patent Application Serial No. 12/485,546, was based on unexpected discoveries that (1) SSEA-3, the immediate precursor of Globo H, is expressed at 25 WO 2010/005598 PCT/US2009/004519 a high level in breast cancer stem cells and therefore can serve as a suitable target for breast cancer treatment, and (2) a-galactosyl-ceramide (a-GalCer) is an effective adjuvant that promotes production of anti-Globo H and anti-SSEA-3 antibodies. [01131 U.S. Patent Application Serial No. 12/485,546 features an immune composition containing Globo H or its fragment (e.g., SSEA-3) and an adjuvant (e.g., a-GalCer). Globo H or its fragment can be conjugated with Keyhole Limpet Hemocyanin (KLH). When administered into a subject (e.g., a human), this immune composition elicits immune responses (e.g., antibody production) targeting Globo H or its fragment and, therefore, is effective in treating cancer (e.g., breast cancer, prostate cancer, ovarian cancer, and lung cancer). [0114] U.S. Patent Application Serial No. 12/485,546 relates to a method of producing antibody specific to Globo H or its fragment by administering to a non-human mammal (e.g., mouse, rabbit, goat, sheep, or horse) the immune composition described above and isolating from the mammalian antibody that binds to Globo H or its fragment. [01151 The Globo H or other glycans described in the instant disclosure is conjugated to a protein carrier, such as DT-CRMI197. They can then be mixed with an adjuvant, such as C34 and optionally a pharmaceutically acceptable carrier (e.g., a phosphate buffered saline, or a bicarbonate solution) to form an immune composition (e.g., a vaccine) via conventional methods. See, e.g., U.S. Patents. 4,601,903; 4,599,231; 4,599,230; and 4,596,792. The composition may be prepared as injectables, as liquid solutions, or emulsions and the carrier is selected on the basis of the mode and route of administration, as well as on the basis of standard pharmaceutical practice. Suitable pharmaceutical carriers and diluents, and pharmaceutical necessities for their use, are described in Remington's Pharmaceutical Sciences. The immune composition preferably contains a-GalCer as an adjuvant. Other examples of adjuvant include, but are not limited to, a cholera toxin, Escherichia coli heat labile enterotoxin (LT), liposome, immune-stimulating complex (ISCOM), or immunostimulatory sequences oligodeoxynucleotides (ISS-ODN). The composition can also nclude a polymer that facilitates in vivo delivery. See Audran R. et al. Vaccine 21:1250-5, 2003; and Denis-Mize et al. Cell Immunol., 225:12-20, 2003. When necessary, it can further contain minor amounts of auxiliary substances such as wetting or emulsifying agents, or pH buffering agents to enhance the ability of the composition to elicit immune responses against 26 WO 2010/005598 PCT/US2009/004519 the sugar moiety in Globo H or its fragment. The immune composition described herein can be administered parenterally (e.g., intravenous injection, subcutaneous injection or intramuscular injection). Alternatively, other modes of administration including suppositories and oral formulations may be desirable. For suppositories, binders and carriers may include, for example, polyalkalene glycols or triglycerides. Oral formulations may include normally employed incipients such as, for example, pharmaceutical grades of saccharine, cellulose, magnesium carbonate and the like. These compositions take the form of solutions, suspensions, tablets, pills, capsules, sustained release formulations or powders and contain 10 95% of the immune composition described herein.

Alternatively, other modes of administration including suppositories and oral formulations may be desirable. For suppositories, binders and carriers may include, for example, polyalkalene glycols or triglycerides.

These compositions take the form of solutions, suspensions, tablets, pills, capsules, sustained release formulations or powders and contain 10-95% of the immune composition described herein. [01171 The immune composition is administered in a manner compatible with the dosage formulation, and in an amount that is therapeutically effective, protective and immunogenic. The quantity to be administered depends on the subject to be treated, including, for example, the capacity of the individual's immune system to synthesize antibodies, and if needed, to produce a cell-mediated immune response. Precise amounts of active ingredient required to be administered depend on the judgment of the practitioner. However, suitable dosage ranges are readily determinable by one skilled in the art. Suitable regimes for initial administration and booster doses are also variable, but may include an initial administration followed by subsequent administrations. The dosage of the vaccine may also depend on the route of administration and varies according to the size of the host. [0118] The immune composition of this invention can also be used to generate antibodies in animals for production of antibodies, which can be used in both cancer treatment and diagnosis. Methods of making monoclonal and polyclonal antibodies and fragments thereof in 27 WO 2010/005598 PCT/US2009/004519 animals (e.g., mouse, rabbit, goat, sheep, or horse) are well known in the art. See, for example, Harlow and Lane, (1988) Antibodies: A Laboratory Manual, Cold Spring Harbor Laboratory, New York. The term "antibody" includes intact immunoglobulin molecules as well as fragments thereof, such as Fab, F(ab')2, Fv, scFv (single chain antibody), and dAb (domain antibody; Ward, et. al. (1989) Nature, 341, 544). Globo H-DT-CRMJ97 and related vaccines [01191 Globo H (1) and its fragments 2-10 were synthesized by methods described herein. For protein conjugation, purified Globo H half ester 12 was incubated with individual carrier proteins as shown in Figure 14. [0120] The Globo H-protein conjugates were characterized by MALDI-TOF analysis to determine the number of Globo H molecules on each carrier protein. The average number of Globo H incorporation is listed in Table 1. Table 1. MALDI-TOF analysis of Globo H incorporation. Ref Protein After Average Carbohydrate MW Gl ycosyliona Incorporation percentage S----------(n) GH-BSA 66431 66449 76029 8 14.4% GH-DT 58472 58326 62138 2~4 6.8% GH-TT 150682 155609 162902 6 4.5% GH-KLH* 8.6 x 106 -700 14.7% GH-Bamboo 25kDx1600 N.D. [01211 'Peak m/z in MALDI-TOF; N.D.: Not determined; *GH-KLH was provided by Optimer Inc. 10122] The GH-KLH conjugate showed the greatest number of Globo H incorporation, mostly due to the larger size and more Lys residues of KLH. The same coupling procedure using p-nitrophenyl linker was also applied to bamboo mosaic virus which contains more than 100,000 lysine residues on the coat of virus. However, the instability of the virus while reacting in sodium phosphate buffer (pH = 7.2) at 4 "C is a major concern for further development. Additionally, the GH-BaMV 16 limits its detection by MALDI-TOF analysis due to its tremendous size. [0123] The synthetic Globo H and truncated fragments (Fig 1) were attached with a pentylamine linker at the reducing ends and covalently immobilized onto the NHS-coated glass slide. Nine of the eleven oligosaccharides were selected to be printed on the microarray. 28 WO 2010/005598 PCT/US2009/004519 Each microarray slide was spotted with 50 pM of nine Globo H analogs (SSEA-4, GH, Gb5, Gb4, Gb3, Gb2, 1B4, 133, and B132) respectively in 12 replications. [01241 To validate the carbohydrates on the microarray, mouse monoclonal antibodies (VK9 and Mbrl for Globo H, and anti-SSEA-3) were used and respective secondary antibodies (goat anti-mouse IgG and IgM) were used to examine the binding specificity, and the results are shown in Fig 2A-2C. The data suggested that VK9 and Mbrl both recognized Globo H and the outer tetrasaccharide BB4. though MBrI also slightly recognized 133. In addition, anti-SSEA-3 antibody specifically recognized SSEA-3 antigen (Gb5) without any cross reactivity. The results indicated that the Globo H microarray could be employed to profile the specificity and potency of polyclonal antibodies from immunized mice. [01251 As previously reported, immunization of mice with a fully synthetic Globo H vaccine and co-administered with QS-21 resulted in the generation of antibodies against human breast cancer cells; however the mouse antibodies are mainly IgM, even after several boosting vaccinations. (Ragupathi G, et aL (1997) Angew Chem Int Ed 36:125-128). 101261 A group of mice were immunized with 1 pg synthetic Globo H-conjugates with or without the glycolipid adjuvant, a-GalCer (Cl) subcutaneously. It was found that GH-KLH, GH-DT and GH-BV are the most effective immunogens for IgM induction, followed by GH TT, and GH-BSA as summarized in Fig. 3A, and a-GalCer is capable of stimulating the immune response to induce high levels of IgM antibodies. A similar trend was also observed in mouse IgG antibodies (Fig. 313), and the relative IgG levels were higher than IgM levels. In brief, despite the lower carbohydrate density of the synthetic glycoconjugate, GH-DT exhibited a similar immunogenicity to GH-KLH, and the adjuvant a-GalCer was shown to enhance the immune response. 101271 Since a-GalCer has been shown to be an effective adjuvant for GH-DT, other glycolipids with better adjuvant activity than Cl were examined as shown in Figure 4. Groups of mice were immunized with GH-DT and GH-BV with or without glycolipids. Sera were obtained and introduced to glycan microarray analysis. In general, mouse anti-Globo H IgG titers increased as immunization proceeded but the IgM levels were almost independent of vaccination times (Fig. 5). Among the GH-BV vaccinated groups, there is no significant difference in the IgM level between glycolipid-vaccine treatment and the vaccine alone. 29 WO 2010/005598 PCT/US2009/004519 Although the results suggested that GH-BV in combination with glycolipid was not an effective immunization regimen, the poor immunogenicity may result from the unstable feature of BaMV. Nevertheless, the a-GalCer analogs, especially 7DW8-5 cooperated well with GH-DT to induce mouse immune response. 101281 Interestingly, the mouse polyclonal IgG antibodies generated by GH-DT and various glycolipid adjuvants not only neutralize Globo H but also cross-react with Gb5, SSEA-4 and Gb4 and C34 appears to be the most effective glycolipid adjuvant (Fig. 6). In order to search for a new composition of vaccine that can induce much higher titer of IgG than IgM, Globo H-DT conjugate and glycolipid CI or C34 or commercially available adjuvant AIPO 4 (aluminium phosphate) or MF59 were tested. 101291 Surprisingly, Globo H-DT with glycolipid C34 induces IgG antibody almost exclusively after the 3 1 vaccination (Fig. 7). To summarize, the novel glycolipid adjuvant 7DW8-5 combined with GH-DT conjugates was able to enhance both anti-Globo H IgG and IgM antibodies, and glycolipid adjuvant C34 combined with GH-DT can induce antibody titer of IgG much higher than IgM. They also exhibited diverse binding affinity to SSEA-3 (Gb5) and SSEA-4 antigens, both specifically expressed on the surface of breast cancer stem cells. [01301 In order to further compare the effect of different glycolipid adjuvants on Globo H vaccine, we immunized seven groups of mice with GH-KLH. The results suggested that mice vaccinated with glycolipids induced higher levels of anti-Globo H antibodies (Fig. 8). Although MF59 is a strong adjuvant it failed to collaborate with GH-KLH to induce antibodies against Globo H. APO 4 (aluminium phosphate) also showed no obvious impact on the induction of antibodies. On the other hand, GH-KLH along with C34 showed superior immunogenicity after the first and second vaccinations but exhibited no significant difference to Cl after the third vaccination. Overall, these findings suggest the potential of novel glycolipid derivatives as adjuvants for carbohydrate based vaccines. [01311 The nature of cellular and humoral immune response is influenced not only by antigen and adjuvant combinations but also by the carrier and route of immunization. As Sesardic and co-workers described, DT-CRM197, a mutant toxin devoid of toxic activity induces antigen specific T cell proliferation and elevates splenocyte production of IL-2, IFN-y and IL-6, suggesting its role in ThI driven pathway.(Miyaji EN et al. (2001) Infect Immun 69:869-874; 30 WO 2010/005598 PCT/US2009/004519 Godefroy S, et al. (2005) Infect Immun 73:4803-4809; Stickings P, et aL (2008) Infect Immun 76:1766-1773.) Despite the fact that the cytokine profile was predominantly ThI, subclasses of anti-CRM 197 antibodies were IgG I with no detectable IgG2a, which suggests a mixed Thl/Th2 response. These results prompted the evaluation of the antibody isotype profile of the Globo H vaccines, and present studies showed that GH-DT or GH-KLH in combination with glycolipid adjuvants induced mainly IgG I antibody with a trace amount of IgG2a (Fig. 9). [01321 Despite the fact that glycolipid adjuvants enhanced Thi biased cytokines secretion when administrated alone intravenously (i.v.), the antibody class switch (IgG2a) was not observed. Overall, the glycolipids play a pivotal role in enhancing both cellular and humoral immune response. Globo H, SSEA-3 and SSEA-4 Cancer Vaccines [0133] SSEA-3 (Gb5) and SSEA-4 conjugated with DT were synthesized and tested. After 3 vaccination, antibodies titer of IgM and IgG were compared and it was found that SSEA-3 DT and SSEA-4-DT also induced much higher titer of IgG than IgM (Fig. 10). [01341 Since GH-DT and C34 induced antibodies to recognize Globo H, Gb5 and SSEA-4, the specificity of SSEA-3-DT and SSEA-4-DT vaccines in the presence of adjuvants using an array of 24 glycans were examined with focus on the study of IgG (Fig. 11). [0135] As shown in Fig. 12, mice immunized with Globo H-DT and C34 adjuvant induced antibodies that can recognize Globo H, SSEA-3 (Gb5) and SSEA-4 with high selectivity, and vaccine SSEA-3-DT with adjuvant MF59 induced high immune response with low selectivity. On the other hand, SSEA-3-DT combined with adjuvant C34 only induced antibodies against Globo H, SSEA-3, and SSEA-4. [01361 Interestingly, SSEA-4-DT (sialyl-Gb5) in the presence or absence of adjuvants induced IgG and IgM antibodies specifically recognizing SSEA-4 and its truncated structures (SSEA-4 with head lactose deletion). Without being bound by theory, it is postulated that sialic acid is highly immunogenic and induces highly specific immune response. 101371 Immunization of mice with SSEA-3-DT-C34 induced antibodies reactive with Globo H, SSEA-3 and SSEA-4, suggesting that a Globo H-based vaccine can target tumor cells and breast cancer stem cells expressing Globo H, SSEA-3 and SSEA-4. 31 WO 2010/005598 PCT/US2009/004519 101381 Immunization of mice with Globo H-DT-C34 induced antibodies reactive with Globo H, SSEA-3 and SSEA-4, suggesting that a Globo H-based vaccine can target tumor cells and breast cancer stem cells expressing Globo H, SSEA-3 and SSEA-4. [01391 Immunization of mice with SSEA-4-DT induced antibodies reactive with SSEA-4, suggesting that a SSEA-4-DT -based vaccine can target tumor cells and breast cancer stem cells expressing SSEA-4. Tumor Size Reduction by Cancer Vaccines 101401 In order to directly assess the efficacy of the synthetic glycoconjugate vaccines, the tumor sizes were measured three times per week as shown in Fig. 13. In general, tumor grows 2 weeks after injection with 4T1, a Globo H bearing breast cancer cell line. All the vaccinated groups along with glycolipid adjuvants still showed comparative smaller tumor progression compared to GH-DT alone and PBS control at day 24. The data suggest that vaccination with GH-DT and a glycolipid adjuvant delayed some degree of the tumor progression in vivo. Expression of SSEA-3 and SSEA-4 in breast cancer and BCSCs [01411 The expression of Globo H in BCSCs, but at a lower frequency than non-BCSCs, and a higher frequency of SSEA-3 expression than Globo H expression in breast cancer and BCSCs has been shown. (Chang W-W. et al., (2008) Proc NAatl Acad Sci USA 105(33):11667 11672, incorporated herein by reference in its entirety.) 101421 The clinical characteristics of 35 patients with breast cancer in whom range of SSEA-3 or SSEA-4 expression was measured, are summarized in Table 2. The median age was 48 years (ranging from 31 to 82 years). They consisted of I stage 0, 10 stage 1, 19 stage II, and 5 stage III. A majority of the tumor specimens had the pathology of infiltrating ductal carcinoma (80.0%), with 51.4% positive for ER and 65.7% positive for node involvement. In Table 2, the ranges of SSEA-3 or SSEA-4 expression is represented by the percentage of positive cells within total cancer cells. A t test was used for statistical analysis of SSEA-3 or SSEA-4 expression relative to HER-2 or nodal involvement status. HER-2 expression was determined by immunohistochemistry. There was no significant correlation between expression level of SSEA-3 or SSEA-4 on tumors and various clinico-pathological factors, such as stage (SSEA-4: P = 0.3498; SSEA-3:, P=0.931 1), or HER-2 (SSEA-4: P = 0.0142; SSEA-3:, P=0.0128) (Table 2). 32 WO 2010/005598 PCT/US2009/004519 Table 2.

To compare the SSEA-3 or SSEA-4 expression between BCSCs and non-BCSCs, CD45- tumor cells were further separated into BCSCs and non-BCSCs based on their expressions of surface markers. The BCSCs were identified as CD45^/CD24--/CD44* cells; the rest of the CD45~ population were considered as non-BCSCs. 33 WO 2010/005598 PCT/US2009/004519 [01441 Using this approach, the expression of SSEA-3 or SSEA-4 in BCSCs and non-BCSCs were evaluated in 35 tumor specimens. Overall, SSEA-4 was detected in 34/35 (97.1%) and SSEA-3 in 27/35 (77.1%) of the tumors (Table 3). SSEA4 or SSEA3 expression was determined by flow cytometry. BCSCs were defined as CD45~CD24-CD44 cells and non BCSCs were defined as the remaining populations of CD45' cells. Range was calculated as percentage of positive cells in total cells. 101451 As summarized in Table 3, among the 27/35 (77.1%) samples expressing SSEA-3, the percentage of positive cells ranged from 1.4% to 66.4%. The non-BCSCs isolated from 25/35 tumors expressed SSEA-3, with the percentage of positive cells ranging from 24.3% to 70.4%. In comparison, BCSCs from 23 of 35 (65.7%) tumors showed positive staining for SSEA-3, with the percentage of positive cells ranging from 5.0% to 58.4%. 101461 Among the 34/35 (97.1%) samples expressing SSEA-4, the percentage of positive cells ranged from 0.5% to 77.1%. The non-BCSCs isolated from 32/35 tumors expressed SSEA-4, with the percentage of positive cells ranging from 24.0% to 78.1%. In comparison, BCSCs from 31 of 35 (88.6%) tumors showed positive staining for SSEA-4, with the percentage of positive cells ranging from 5.6% to 83.6%. Table 3.

The BCSCs were identified as CD45-/CD24-/CD44* cells; the rest of the CD45 population were considered as non-BCSCs. The expression of SSEA-4 within each of these 34 WO 2010/005598 PCT/US2009/004519 two gated populations varied among tumor samples a shown in Figure 15. For instance, BCSCs of patient BC0264, which accounted for 5.7% of the total isolated tumor cells, were negative for SSEA-4, whereas 60.3% of the non-BCSCs expressed SSEA-4. For patient BC0266, SSEA-4 expression was detected in 59.4% of non-BCSCs and 55.7% of BCSCs. For patient BC0313, SSEA-4 expression was detected in 32.4% of non-BCSCs and 83.6% of BCSCs. Altogether, SSEA-4 was detected in 34/35 (97.1%) samples tested with the percentage of positive cells ranging from 0.5% to 77.1%). (Table 32). Expression of SSEA-3 and SSEA-4 in Normal Tissues 101481 Using tissue microarray, SSEA-4 expression was analyzed among 20 different organs by immunohistochemical staining, as shown in Table 4 (E, epithelial; C, connective tissue).

Further, in a manner similar to Globo H and SSEA-3 (Chang W W. et al., (2008) Proc Natl Acad Sci USA 105(33):11667-11672), SSEA-4 expression was 35 WO 2010/005598 PCT/US2009/004519 confined mainly to the cytoplasm or apical surface of epithelial cells which were essentially inaccessible to the immune system, as shown in Figure 16. [01501 By comparison, Globo H is expressed on the epithelial cells of several glandular tissues, such as breast, gastrointestinal tract, pancreas, prostate, and uterine cervix. The distribution of SSEA3 is similar to that of Globo H except for its absence in normal breast tissues but presence in kidney, rectum, testis, and thymus, which were negative for Globo H (Chang W-W. et al., (2008) Proc Natl Acad Sci USA 105(33):11667-11672).

EXAMPLE 1: Synthesis of Globo H coniugated with different carrier proteins [01551 Globo H (1; see Figure 11) and its fragments 2-10 were synthesized by using a programmable one-pot strategy. (Huang C-Y, et al. (2006) Proc Natl Acad Sci USA 103:15 20.) The reaction of I was carried with an efficient homobifunctional linker in anhydrous DMF solution at room temperature. (Wu X, et al. (2004) Org Lett 6:4407-4410; Wu X, Bundle DR (2005) J Org Chem 70:7381-7388.) The reaction was readily monitored by TLC. Once the disappearance of the free amine with a larger Rf product occurred, the reaction mixture was evaporated to remove DMF, and washed with dichloromethane and water to remove the excess amount of linker. Finally, the product was purified by reverse phase (C18) column chromatography, and gradually eluted with water containing 1% acetic acid to 40% methanol in water. The solution was then lyphophilized to yield the light yellow product 12. Finally, for protein conjugation, the purified Globo H half ester 12 (30-40 equiv) was incubated with individual carrier proteins in phosphate buffer (10 mM, pH 7.2) for 24 hours at room temperature (Figure 14). Importantly, the protein concentration must be adjusted to -5 mg/mL to maximize the coupling of lysine residues with Globo H half ester. After 24 h, the glycoconjugates were then diluted, and dialyzed against deionized water to remove the 37 WO 2010/005598 PCT/US2009/004519 remaining ofp-nitrophenyl group. The solution was then lyphophilized to a white powder to give 13, 14, and 15. [01561 The Globo H-protein conjugates were characterized by MALDI-TOF analysis to determine the number of Globo H molecules on each carrier protein. The average number of Globo H incorporation is listed in Table I shown supra. [01571 The glycoconjugates 13, 14, 15 were dissolved in ddH 2 0 to yield a final concentration around 1 pmol/pL. Sinapinic acid was selected as a matrix and mixed with freshly prepared acetonitrile and deionized water (1 : 1 v/v) to make the final matrix concentration in 10 mg/mL including 0.1% TFA. Each sample was detected under a linear positive mode to get the m/z spectrum. The molecular weight of each glycoconjugate was determined by m/z. The glycoconjugate 14 showed heterogeneity, indicating an average of 2-4 incorporations. The GH-KLH conjugate showed the greatest number of Globo H incorporation, mostly due to the larger size and more Lys residues of KLH. The same coupling procedure using p-nitrophenyl linker was also applied to bamboo mosaic virus which contains more than 100,000 lysine residues on the coat of virus. However, the instability of the virus while reacting in sodium phosphate buffer (pH = 7.2) at 4 "C is a major concern for further development. Additionally, the GH-BaMV 16 limits its detection by MALDI-TOF analysis due to its tremendous size. Finally, the lyphophilized glycoconjugates were stored at -30 "C and reconstituted with sterile water before immunization. EXAMPLE 2: Glycan microarray fabrication and validation: 101581 The synthetic Globo H and truncated fragments (Fig 1) were attached with a pentylamine linker at the reducing ends and covalently immobilized onto the NHS-coated glass slide. Nine of the eleven oligosaccharides were selected to be printed on the microarray. Serial oligosaccharide concentrations (1, 5, 10, 20, 40, 50, 80, 1 00JM) were tested to optimize the binding affinity and fluorescence intensity. Each microarray slide was spotted with 50 jpM of nine Globo H analogs (SSEA-4, GH, GbS, Gb4, Gb3, Gb2, BB4, 133, and 132) respectively in 12 replications. After reaction in 80% humidity atmosphere, the slides were stored at room temperature in desiccators before use. [01591 To validate the carbohydrates on the microarray, mouse monoclonal antibodies (VK9 and MbrI for Globo H, and anti-SSEA-3) and respective secondary antibodies (goat anti 38 WO 2010/005598 PCT/US2009/004519 mouse IgG and IgM) were used to examine the binding specificity, and the results are shown in Figs. 2A-2C. The data suggests that VK9 and Mbrl both recognized Globo H and the outer tetrasaccharide BB4, although MBrI also slightly recognized BB3. (Gilewski T el al. (2001) Proc Nati Acad Sci USA 98:3270-3275; Huang C-Y, et aL. (2006) Proc Natl Acad Sci USA 103:15-20.) In addition, anti-SSEA-3 antibody specifically recognized SSEA-3 antigen (Gb5) without any cross reactivity. The results indicated that the Globo H microarray could be employed to profile the specificity and potency of polyclonal antibodies from immunized mice. EXAMPLE 3: Mouse immunization [01601 In this study, a group of mice was immunized with I pg synthetic Globo H (GH) conjugates with or without the glycolipid adjuvant, a-GalCer (Cl) subcutaneously. Ten days after three vaccinations at weekly intervals, mice sera were collected and subsequently introduced to the glycan microarray to evaluate the antibody levels. It was found that GH KLH, GH-DT and GH-BV are the most effective immunogens for IgM induction, followed by GH-T, and GH-BSA as summarized in Fig. 3A, and a-GalCer is capable of stimulating the immune response to induce high levels of IgM antibodies. A similar trend was also observed in mouse IgG antibodies (Fig. 3B), and the relative IgG levels were higher than IgM levels. In brief, despite the lower carbohydrate density of the synthetic glycoconjugate, GH-DT exhibited a similar immunogenicity to GH-KLH, and the adjuvant a-GalCer was shown to enhance the immune response. [01611 Since Cl was shown to be an effective adjuvant for GH-DT, other glycolipids with better adjuvant activity than CI were examined as shown in Fig 4. (Fujio M, et aL. (2006) J Am Chem Soc 128:9022-9023.) 101621 Groups of mice were immunized intramuscularly with 1.6 pg of GH-DT and GH-BV with or without 2 pg of glycolipids twice a week. Sera were obtained two weeks after the third vaccination and introduced to glycan microarray analysis. In general, mouse anti-Globo H IgG titers increased as immunization proceeded but the IgM levels were almost independent of vaccination times (Fig. 5). Among the GH-BV vaccinated groups, there was no significant difference in the IgM level between glycolipid-vaccine treatment and the vaccine alone. Although the results suggested that GH-BV in combination with glycolipid 39 WO 2010/005598 PCT/US2009/004519 was not an effective immunization regimen, the poor immunogenicity may result from the unstable feature of BaMV. Nevertheless, the a-GalCer analogs, especially 7DW8-5 cooperated well with GH-DT to induce mouse immune response. [01631 Interestingly, the mouse polyclonal IgG antibodies generated by GH-DT and various glycolipid adjuvants not only neutralize Globo H but also cross-react with Gb5, SSEA-4 and Gb4 and C34 appears to be the most effective (Fig. 6). In order to search for a new composition of vaccine that can induce much higher titer of IgG than IgM, Globo H-DT conjugate and glycolipid Cl or C34 and commercially available adjuvant AIPO 4 (aluminium phosphate) or MF59 were tested. Surprisingly, Globo H-DT with glycolipid C34 can induce almost IgG antibody after 3 vaccination (Fig. 7). In summary, the novel glycolipid adjuvant 7DW8-5 combined with GH-DT conjugates was able to enhance both anti-Globo H IgG and IgM antibodies, and glycolipid adjuvant C34 combined with GH-DT can induce antibody titer of IgG much higher than IgM. They also exhibited diverse binding affinity to Gb5 and SSEA 4 antigens, both specifically expressed on the surface of breast cancer stem cells. 101641 In order to further compare the effect of different glycolipid adjuvants on Globo H vaccine, seven groups of mice with GH-KLH. were immunized The results suggested that mice vaccinated with glycolipids induced higher levels of anti-Globo H antibodies (Fig. 8). Although MF59 is a strong adjuvant it failed to collaborate with GH-KLH to induce antibodies against Globo H. AIPO 4 (aluminium phosphate) also showed no obvious impact on the induction of antibodies. On the other hand, GH-KLH along with C34 showed superior immunogenicity after the first and second vaccinations but exhibited no significant difference to CI after the third vaccination. [0165] DT-CRM197, a mutant toxin devoid of toxic activity induces antigen-specific T cell proliferation and elevates splenocyte production of IL-2, IFN-y and IL-6, suggesting its role in ThI driven pathway.(Miyaji EN et al. (2001) Infect Immun 69:869-874; Godefroy S, et al. (2005) Infect Immun 73:4803-4809; Stickings P, et al. (2008) Infect Immun 76:1766-1773.) Despite the fact that the cytokine profile was predominantly Thl, subclasses of anti-CRM197 antibodies were IgGI with no detectable IgG2a, which suggests a mixed ThI/Th2 response. These results prompted the evaluation of the antibody isotype profile of the Globo H vaccines, and present studies showed that GH-DT or GH-KLH in combination with glycolipid adjuvants induced mainly IgG1 antibody with a trace amount of IgG2a (Fig. 9). 40 WO 2010/005598 PCT/US2009/004519 101661 Despite the fact that glycolipid adjuvants enhanced Thi biased cytokines secretion when administrated alone intravenously (i.v.). the antibody class switch (IgG2a) was not observed. Overall, the glycolipids play a pivotal role in enhancing both cellular and humoral immune response. [01671 Gb5 and SSEA-4 conjugated with DT were also synthesized by the same strategy. After 3d vaccination, antibodies titer of IgM and IgG were compared and it was found that Gb5-DT and SSEA-4-DT also induced much higher titer of IgG than IgM (Fig. 10). EXAMPLE 4: Specificity studies of antibodies induced by different vaccine composition. [01681 Since GH-DT and C34 induced antibodies to recognize Globo H, Gbs (SSEA-3) and SSEA-4, the specificity of SSEA-3-DT and SSEA-4-DT vaccines in the presence of adjuvants using an array of 24 glycans with focus on the study of IgG were next examined (Fig. 11). 101691 As shown in Fig. 12, mice immunized with Globo H-DT and C34 adjuvant induced antibodies that can recognize Globo H, SSEA-3 (Gb5) and SSEA-4 with high selectivity, and vaccine SSEA-3-DT with adjuvant MF59 induced high immune response with low selectivity. On the other hand, SSEA-3-DT combined with adjuvant C34 only induced antibodies against Globo H, SSEA-3, and SSEA-4. [01701 Interestingly, SSEA-4-DT in the presence or absence of adjuvants induced IgG and IgM antibodies specifically recognizing SSEA-4 and its truncated structures (SSEA-4 with head lactose deletion). It is however not clear about the origin of the selectivity. [01711 In order to directly assess the efficacy of the synthetic glycoconjugate vaccines, the tumor sizes three times per week were measured as shown in Fig. 13. In general, tumor grows 2 weeks after injection with 4T1, a Globo H bearing breast cancer cell line. All the vaccinated groups along with glycolipid adjuvants still showed comparative smaller tumor progression compared to GH-DT alone and PBS control at day 24. The preliminary data suggested that vaccination with GH-DT and a glycolipid adjuvant indeed delayed some degree of the tumor progression in vivo. EXAMPLE 5: Preparation of Globo H half ester 101721 The GloboH half ester was prepared as follows: 41 WO 2010/005598 PCT/US2009/004519 HO OH HO IOH H OH HO- a NHAcH H -OH O O OH 0 HO o2H H O Globo H half ester (12) [01731 Globo H amine 1 (5 mg, 4.54 pmol) was dissolved in anhydrous DMF solution. p nitrophenyl ester linker (8.8 mg, 22.7 pmol) was then added and stirred for 1-3 hours at room temperature. The reaction was monitored by TLC (1% AcOH in methanol) and Ninhydrin test. The disappearance of free amine with a larger Rr product indicated the completion of the reaction.

The mixture was stirred gently for 24 h at room temperature. The mixture was then diluted with deionized water and dialyzed against 5 changes of deionized water. The solution was then lyphophilized to a white powder. The obtained Globo H-protein conjugates can be characterized by MALDI-TOF analysis to determine the carbohydrate incorporation rate. 41 (GH-BSA), MALDI-TOF found 76029, 42 (GH-DT-CRMI197) found 62138, 43 (GH-T T) found 162902, 44(GH-BaMV) was not determined EXAMPLE 7: MALDI-TOF MS analysis for alvcoconiugates [01761 The glycoconjugates 41, 42, 43 and primary carrier proteins were reconstituted with ddH 2 O (~1 pg/il). The matrix, sinapinic acid, was freshly prepared with acetonitrile and deionized water 1 : 1, making final matrix concentration in 10 mg/ml including 0.1% TFA. Gently loaded and mixed the matrix solution and glycoconjugates, then air dried the plate. Calibration was imperative using bovine serum albumin before measurement. Each glycoconjugate and primary protein sample was detected under linear positive mode. The average molecular weight allows the calculation of the average number of carbohydrate incorporated on the carrier protein. EXAMPLE 8: Glyean microarray fabrication 101771 Microarray were printed (BioDot, Cartesian Technologies, USA) by robotic pin (SMP3, TeleChem International Inc., USA) deposition of -0.7 nL of various concentrations of amine-containing glycans in printing buffer (300 mM phosphate buffer, pH 8.5 containing 0.005% Tween-20) from a 96 well onto NHS-coated glass slides. Each microarray slide was spotted with 50 pM of nine Globo H analogs (SSEA-4, GH, Gb5, Gb4, Gb3, Gb2, BB4, BB3, and BB2) respectively in 12 replications. Printed slides were allowed to react in an 43 WO 2010/005598 PCT/US2009/004519 atmosphere of 80% humidity for an hour followed by desiccation overnight. These slides were stored at room temperature in a dessicator before used. EXAMPLE 9: Serologic assay (Glycan microarray) [0178] Mice sera were diluted 1: 60 with 0.05% Tween 20 in 3% BSA/PBS buffer (pH 7.4) as preliminary screening. The glycan microarray was blocked with 50 mM ethanolamine for I h, and washed twice with ddH 2 0 and PBS buffer before used. The serum dilutions were then introduced to the Globo H microarray, and incubated at room temperature for I h. The microarray slides were further washed three times with PBST (0.05% Tween-20 in PBS buffer) and PBS buffer, respectively. Next, Cy3-affiniPure goat anti-mouse IgG (H + L), IgGI, IgG2a or anti-mouse IgM was added to the microarray slide and then sealed for 1 hour incubation at room temperature. Finally, the slides were washed three times with PBST, PBS and ddH 2 0 in sequence. The microarray slides were dried before scanned at 532 nm with a microarray fluorescence chip reader (Genepix 4000B). Data were analyzed by software GenePix Pro 6.0 (Axon Instruments, Union City, CA, USA). To acquire the accurate measurement, PMT gain was adjusted to 400 avoiding fluorescence saturation. The local background was subtracted from the signal at each glycan spot. The spots with obvious defects or no detectable signal were omitted. The ultimate fluorescence intensity was defined as the average of "medians of F532 nm - B532 nmn" from replicate spots. EXAMPLE 10: Serologic assay (Enzyme-Linked Immunosorbent Assay) 101791 0.2 pg of Globo-H ceramide in 100 pl carbonate bicarbonate buffer (pH 10) was coated in 96-well plate (NUNC) at 4 "C for overnight.

Serial dilutions of mice sera were added into each well and incubated for I h at room temperature, followed by washing with DPBST (Dulbecco's Phosphate Buffered Saline, 0.05% Tween20). Goat anti-mouse IgG-AP (I : 200, Southern Biotech., USA) was added and incubated for 45 minutes at room temperature. The plates were washed with PBST five times and then incubated with alkaline phosphatase substrate, p-nitrophenyl phosphate (Sigma) for 8 minutes at 37 "C. After incubation, the reaction was stopped by adding 3 M NaOH solution and the plates were read at 405 nrm on the ELISA reader (SpectraMax, Molecular Devices) The titer was defined as the highest dilution yielding an optical density greater than 0.1. 44 WO 2010/005598 PCT/US2009/004519 EXAMPLE 11: Dosage and Immunization [0180] (1) Groups of three mice (6-week-old female C57BL/6 mice, BioLASCO, Taiwan) were administered subcutaneously to abdomen region with GH-KLH (Optimer Inc.), GH BSA, GH-TT, GH-CRM 197, and GH-BaMV respectively with or without glycolipid adjuvant CI or 7DW8-5 for three times with weekly interval.
