Description

Epidermal growth factor receptor inhibitors

Field of the invention

The present invention relates to novel epidermal growth factor receptor (EGFR) inhibitors, also to pharmaceutically acceptable salts, solvates or stereoisomers thereof, to pharmaceutical compositions comprising the present compounds, to methods for treating diseases or disorders and use of the present compounds as pharmaceutical products for treating diseases or disorders.

Background of the invention

Epidermal Growth Factor Receptor (EGFR) is a transmembrane glycoprotein — tyrosine kinase that is a member of the erbB receptor family. EGFR consists of a glycosylated external ligand-binding domain (621 residues) and a cytoplasmic domain (542 residues) bound by a short 23-amino-acid transmembrane linker. The extracellular portion of EGFR contains 25 disulfide bonds and 12 N-linked glycosylation sites, and is generally considered to consist of four subdomains. X-ray crystal structures of EGFR suggest that the receptor may adopt both an autoinhibited tethered-conformation that cannot bind epidermal growth factor (EGF) (Ferguson et al., Mol Cell, 2003, vol 11 :507-517) and an active conformation that may mediate EGF ligand binding and receptor dimerisation (Garrett et al., Cell 2002, vol 110:763-773; Ogiso et al., Cell, 2002, vol 110:775-787). Upon binding of a growth factor ligand such as epidermal growth factor (EGF), the receptor can homo-dimerise with another EGFR molecule or hetero-dimerise with another family member such as erbB2 (FIER2), erbB3 (HER3), or erbB4 (HER4). Homo- and/or hetero-dimerisation of erbB receptors results in the phosphorylation of key tyrosine residues in the intracellular domain and leads to the stimulation of numerous intracellular signal transduction pathways involved in cell proliferation and survival. Detailed reviews of erbB receptor signalling and its involvement in tumourigenesis have been provided in Ciardiello F. N. Engl J Med 2008; 358: 1160-1174 and Robert Roskoski Jr. Biochemical and Biophysical Research Communications 319 (2004) 1-11.

The link of EGFR to oncological diseases was first recognized when the transforming v- ErbB oncogene of the avian erythroblatosis virus was found to be a mutant homolog of human EGFR (Downward J. Nature. 1984; 307:521-527). The v-erbB oncogene was found to contain recombinations of the transmembrane and cytoplasmic domains of EGFR (Olofsson B. Eur. J. Biochem. 1986; 160:261-266), resulting in EGFR oncogenic aberrations. In addition to mutations, overexpression of EGFR was then determined, promoting the progression of a number of malignant tumours (Gusterson B. Cell Biol. Int. Rep. 1984; 8:649-658), including sarcomas (Gusterson B. Int. J. Cancer. 1985; 36:689-693), non-small cell lung cancer (NSCLC) (Veale D. Br. J. Cancer. 1987; 55:513-516) and malignant gliomas (Wong A.J. Proc. Natl. Acad. Sci. USA. 1987; 84:6899-6903). It is currently known that EGFR regulates numerous cellular processes via tyrosine-kinase mediated signal transduction pathways, including, but not limited to, control of cell proliferation, differentiation, cell survival, apoptosis, tumor angiogenesis, mitogenesis, and metastasis (Atalay et al., Ann. Oncology 14: 1346-1363 [2003]; Herbst R.S. Cancer. 2002; 94: 1593-1611; Modjtahedi et al., Br. J. Cancer. 1996; 73 : 228-235). Overexpression of EGFR has been confirmed in numerous human malignant tumors, including cancers of the bladder, brain, head and neck, pancreas, lung, breast, ovary, colon, prostate, and kidney (Atalay et al., Ann. Oncology 14: 1346- 1363 [2003]; Herbst R.S. Cancer. 2002; 94: 1593-1611; Modjtahedi et al., Br. J. Cancer. 1996; 73: 228-235). EGFR is also expressed in the cells of normal tissues, particularly the epithelial tissues of the skin, liver, and gastrointestinal tract, although typically at lower levels than in malignant cells (Herbst R. S. Cancer. 2002; 94: 1593-1611).

Low molecular weight EGFR tyrosine kinase inhibitors are known to be used in the treatment of oncological diseases, for example, in the treatment of non-small cell lung cancer, pancreatic cancer; anti-EGFR antibodies are used in the treatment of colorectal cancer, and head and neck cancer (Ping Wee. Cancers (Basel). 2017 May; 9(5): 52).

Frequent mutations and EGFR hyperexpression are observed in many oncological diseases (Lu X. Med Res Rev. 2018 Sep; 38(5): 1550-1581), therefore, there remains a need for new effective and safe drugs directed to inhibiting EGFR activity.

Dosage regimens may be adjusted to provide the optimum desired response. For example, a single dose may be administered, several divided doses may be administered over time or the dose may be proportionally reduced or increased as indicated by the exigencies of the therapeutic situation. It is especially advantageous to formulate peroral compositions in a unit dosage form for ease of administration and uniformity of dosage. A unit dosage form as used herein refers to physically discrete units suited as unitary dosages for patients/subjects to be treated; each unit contains a predetermined quantity of active compound calculated to produce the desired therapeutic effect in association with the desired pharmaceutical carrier. Specification for the unit dosage forms of the invention is typically dictated by and directly dependent on (a) the unique characteristics of a therapeutic agent and particular therapeutic or prophylactic effect to be achieved, and (b) the limitations inherent in the art of compounding such an active compound for the treatment of sensitivity in subjects.

Thus, a skilled artisan would appreciate, based upon the disclosure provided herein, that the doses and dosage regimen are adjusted in accordance with methods well-known in the therapeutic arts. That is, the maximum tolerable dose can be readily established, and the effective amount providing a detectable therapeutic effect to a patient may also be determined, as can the temporal requirements for administering each agent to provide a detectable therapeutic effect to a patient. Thus, while certain doses and administration regimens are exemplified herein, these examples in no way limit the doses and administration regimens that may be provided to a patient in practicing the embodiments of the invention.

It is to be noted that dosage values may vary with the type and severity of the condition to be alleviated, and may include single or multiple doses. Furthermore, it is to be understood that for any particular subject, specific dosage regimens should be adjusted over time according to the individual need and the judgment of a medical professional administering or supervising the administration of the compositions, and that dosage ranges set forth in the present description are exemplary only and are not intended to limit the scope or practice of the claimed compositions. Furthermore, the dosage regimen with the compositions of the present invention may be based on a variety of factors, including the type of disease, age, weight, sex, medical condition of the patient, the severity of the condition, the route of administration, and the particular compound of the present invention employed. Thus, the dosage regimen may vary widely, but can be determined routinely using standard methods. For example, doses may be adjusted based on pharmacokinetic and pharmacodynamic parameters, which may include clinical effects such as toxic effects or laboratory values. Thus, the present invention encompasses intra-patient dose-escalation as determined by a qualified specialist. Methods for determining appropriate dosage and regimen are well-known in the art and would be understood by a skilled artisan once provided the ideas disclosed herein.

As a rule, standard daily dosage for an adult human is typically in the range from 0.02 mg to 5000 mg or from about 1 mg to about 1500 mg.

Once improvement of the patient’s conditions has occurred, a maintenance dose is administered, if necessary. Subsequently, the dosage or the frequency of administration, or both, may be reduced, as a function of the symptoms, to a level at which the improved disease, disorder or condition is retained. Patients may be however required periodic treatment on a long-term basis upon any relapse of symptoms.

The foregoing ranges are merely suggestive, as the number of variables in regard to an individual treatment regime is large, and considerable excursions from these recommended values are not uncommon. These dosages may be altered depending on a number of variables, not limited to the activity of the compound used, the disorder or condition to be treated, the method of administration, the requirements of the individual subject, the severity of the disorder or condition being treated, and the judgment of the physician.

The following examples are provided for better understanding of the invention. These examples are for purposes of illustration only and are not to be construed as limiting the scope of the invention in any manner.

All publications, patents, and patent applications cited in this specification are incorporated herein by reference. Although the foregoing invention has been described in some detail by way of illustration and example for purposes of clarity of understanding, it will be readily apparent to those of ordinary skill in the art in light of the teachings of this invention that certain changes and modifications may be made thereto without departing from the spirit or scope of the appended embodiments.
