Description

Australian Patents Act 1990 - Regulation 3.2A ORIGINAL COMPLETE SPECIFICATION STANDARD PATENT Invention Title "Use of imidazoquinolines for the treatment of EGFR dependent diseases or diseases that have acquired resistance to agents that target EGFR family members" The following statement is a full description of this invention, including the best method of performing it known to me/us:- Use of Imidazoquinolines for the treatment of EGFR dependent diseases or diseases that have acautred resistance to agents that target EGFR family members This is a divisional of Australian patent application No. 2008280105, the entire contents of which are incorporated herein by reference. The present invention relates to the use of specific lmldazoquinoline derivatives In the treatment of Epidermal Growth Factor Receptor (EGFR) family members (including EGFR1 also known as HER1 or Erb-B1; EGFR2 also known as HER2 or Erb-B2; and EGFR3 also known as HER3 or Erb-B3) dependent diseases or diseases that have acquired resistance to agents that target EGFR family members, use of said compounds for the manufacture of pharmaceutical compositons for the treatment of said diseases, combinations of said compounds with EGFR modulators for said use, methods of treating said diseases with said compounds, and pharmaceutical preparations for the treatment of said diseases comprising said compounds, alone or in combination, especially with an EGFR modulator. Somatic mutations in the tyrosine kinase domain of EGFR has been associated with the clinical response to EGFR tyrosine kinase Inhibitor such as Gefitinib (lressa@) or Erlotinib (Tarceva@) (Paez at al., EGFR mutations in lung cancer: correlation with clinical response to gefitinib therapy, science, vol 304, 1497-1500). Acquired resistance to EGFR modulators occurs in patients who initially responded clinically to therapy, but then developed progressive tumors. Refractory response to EGFR kinase inhibitors is exemplified with the secondary resistant mutation T790M (Kobayashi et at; EGFR mutation and resistance of non-small cell lung cancer to gefitinib, N. Engi J Med, Vol 352, 786-792), which is comparable to the resistance mutation(s) observed for Gleevec/Glivec or Dasatininb in chronic myelogenous leukemia (CML) (Gorre et al.; Bcr-Abi point mutants isolated from patients with imatinib mesylate resistant chronic leukemia rearnin sensitive to inhibitors of the Bcr-Abi chaperone heat shock protein 90, Biood, vol 100, 3041-3044) or GIST patients (Antonescu et al.; Acquired resistance to Imatinib in gastrointestinal stromal tumors occurs through secondary gene mutation, Cin Cancer Res, Vol 11, 4182-4190). Evidences that activation of the P13K pathway downstream of activated EGFR exists In the literature. Thus, genetic ablation of the P13K catalytic subunit (p110) in mouse embryo fibroblast renders cells resistant for transformation by an activated form of EGFR (Zhao et al.; The p110 alpha Isoform of P13K is essential for proper growth factor signaling and oncogenic transformation, PNAS, vol 103, 16296-16300). HER3 (ErbB-3), one of the four member of the EGFR family and partner of HER1 (EGFR1) is often overexpressed In EGFR inhibitors 2 sensitive tumors, and that is correlated with constitutive P13K recruitment and activation (Engelman at al.; ErbB-3 mediates phosphoinositide 3-kinase activity in gefitinib-sensftive non small cell lung cancer cell lines, PNAS vol 102, 3788-3793; Sergina et al.; Escape from HER-family tyrosine kinase inhibitor therapy by the kinase-inactive HER 3). The genetic and biochemical characterization of tumor biopsies and tumor cell lines harboring EGFR amplification and EGFR Inhibitor resistance have revealed a constitutive activation status of the P13K pathway (Engelman et al.; Allelic disruption obscures detection of a biologically significant resistance mutation in EGFR amplified lung cancer, The Journal of Clinical Investigation, vol 116, 2695-2706). Surprisingly, it has been found that specific Imidazoquinollne derivatives, which have been described in WO2006/122806 provoke strong anti-proliferative activity and an in vivo antitumor response of breast and lung cancer cell lines with amplified EGFRs and/or mutated EGFRI as single agent and in combination with EGFR kinase modulators. Therefore, said compounds are useful[ for the treatment of EGFR dependent disease. Specific imidazoquinoline derivatives which are suitable for the present invention, their preparation and suitable pharmaceutical formulations containing the same are described in WO2006/122806 and include compounds of formula I N RC N_

Female Harlan athymic mice (n = 8), bearing s.c NC-H358 tumor are treated p.o. either with the P13K inhibitor Compound A or with the EGFR Inhibitor NVP-AEE78. or In combination, at the indicated dose and schedule.' p<0.05 (Dunnet's vs controls). Figure_3 shows the antitumor activity of Compound A against the EGFR Inhibitor resistant NSCLC cell line NCI-H1975 S Female Harlan athymic mice (n = 8), bearing s.c NCI-H1975 tumors are treated p.o. with the P13K inhibitor Compound A or with the EGFR inhibitors NVP-AEE788 and erlotinib at the indicated dose and schedule. * p<0.05 (Dunnet's vs controls). Figure 4 shows the level of expression of EGFR family proteins HER-I, -2 and -3, in a panel of 15 breast cancer human tumor cell lines The indicated tumor lines are cultured in optimal growth conditions, and cell extracts prepared at sub-confluent stage. Equivalent total protein extracts are then subjected to SDS PAGE, gels transferred and membranes Ir'ubated with antibodies raised against the proteins indicated on the left side of the panels. Figure 5 shows the antiproliferative activity of Compound A In a panel of breast cancer cell lines. The indicated cell lines are incubated with increasing amount of Compound A, and effect on the proliferation assessed with a Methylene blue viable cell detection assay. The cell lines indicated with a red asterisk are the ones in which cell death is observed (i.e. for which the absorbance observed for treated cells was lower than the original inoculum). Figure 6 shows the antitumor activity of Compound A against BT474 tumors. Female Harlan athymic mice (n = 8), bearing s.c. BT474 tumors are treated p.o. with the P13K inhibitor Compound A at the indicated dose and schedule.* p<0,05 (Dunnet's). A panel of 15 NSCLC tumors cell lines have been characterized for the expression of the EGFR family members (Figure 1). Consistent with the data described in the literature, most of them shows high levels of HERI and 3. This is the case of the NCI-H358 cell line that has also been described as sensitive to EGFR kinase inhibitors. This cell line has been tested with EGFR low-molecular mass kinase inhibitors and compounds of formula I. The Growth Inhibitory 50 (Glio) found for gefitinib in a proliferation assay - methylene blue assay - with this cell line, is 542 nM and the G150 for Compound A is 31 nM. The Combination Index for Compound A and gefitinib In a proliferation assay with NCI-H358 tumor cells is 1.0, reflecting the additive effect of both molecules in this lung tumor cell line. Similar results are obtained with other EGFR inhibitors including NVP-AEE788, erlotinib and lapatinib. Moreover, in vivo combination of such imidazoquinoline derivatives with the EGFR kinase inhibitor NVP- 6 AEE788 results in tumor statis when such compounds are administered to animals bearing subcutaneous NCI-H358 xenografts (Figure 2). Non small cell lung carcinoma cell lines with amplified EGFR, but refractory to EGFR inhibition therapy, are valuable models to test the sensitivity of P13K inhibitors like the compounds of formula I in such genetic background. The NCI-H1 975 cell line Is such a model, as it overexpresses HER1 and HER3 and is highly tumorgenic in vivo. Moreover, it contains HERI bearing the T790M gatekeeper mutation that renders the kinase resistant to catalytic inhibition. The Glsos in this cell line-are 11.4 nM and 3645 nM for Compound A and gefitinib, respectively. The in vivo antitumor activity of P13K inhibitors like the compounds of formula I is tested against this EGFR driven and inhibitor resistant tumor model (Figure 3). As expected, the EGFR kinase Inhibitors NVP-AEE788 and erlotinib show no significant Inhibition on tumor growth, but surprisingly administration of Compound A causes in vivo tumor growth inhibition. Compound A is well tolerated - no statistically significant difference in body weight between the control and treatment groups can be observed. ErB-B2 (HER2) is often overexpressed in breast and ovarian cell lines. The level of expression of this protein In a panel of 15 breast cancer cell lines is shown in Figure 4. Although effective therapeutic approaches exist against ErbB2, 50% of patients with amplifled/overexpressed HER2 do not respond to ErbB2 modulators such as trastuzumab. In a panel of breast tumor cell lines containing or not ErbB2 amplification, Compound A decreases cell proliferation with an median GIro of 11.1 nM, and Induces cell death in cell lines that overexpressed ErbB2 (Figure 5). Moreover, BT474 subcutaneous xenografts are exquisitely sensitive to Compound A treatment, as tumor regression is observed upon daily treatment with the compound at a 45 mg/kg, given po, once per day (Figure 6). A compound of formula I, especially Compound A, Is therefore useful for the treatment of such EGFR dependent diseases, especially malignancies, or EGFR family members acquired resistance driven diseases. Diseases or malignancies with an established or potential molecular link to dysregulation of EGFR activity are, for Instance, described in "Mendelsohn and Baselga; Status of Epidermal Growth Factor Receptor Antagonists in the Biology and Treatment of Cancer, Journal of Clinical Oncology, 2787-2799'; "Mendelsohn and Baselga; Epidermal Growth Factor Receptor Targeting in Cancer, Seminars in Oncology, Vol 33, 369-385"; Inner et al., EGFR Idnase domain mutations - functional impact and 7 relevance for lung cancer therapy, Oncogene, 1-9; Roche-Lima et al., EGFR targeting of solid tumors; Cancer Control, 2007, Vol 14 (3), 295-304) which all are, including the references cited therein, hereby incorporated Into the present application by reference.
