Safety, Pharmacokinetic and Preliminary Efficacy Study of AC0010 in Patients With EGFR T790M Positive NSCLC

Lung cancer remains the most common cancer worldwide with non-small cell lung cancer (NSCLC) accounting for 85% of cases. Molecularly targeted therapies have proven to be superior to chemotherapy for NSCLC patients whose tumors have mutations in EGFR. Recent studies have established tyrosine kinase inhibitors (TKIs) as the gold standard for treating EGFR-mutation-positive NCSLC. However, patients on TKIs eventually progress, and in approximately 50% of cases, progression is due to development of an additional mutation called T790M. AC0010 may provide an effective therapy for a patient population with few alternative treatment options. Pre-clinical data demonstrated that AC0010 inhibits T790M. It is anticipated that AC0010 may promote cell death in tumor cells with the T790M mutation, thus providing possible therapeutic benefit in patients who have developed T790M-mediated resistance to previous TKIs. This is a two-part, open-label study of oral AC0010 administered twice-daily in previously treated NSCLC patients who have documented evidence of an activating mutation in the EGFR gene and have failed treatment with an EGFR inhibitor such as erlotinib, gefitinib or afatinib. This study will include 2 parts: phase 1 : Dose-escalation Period with 28-day cycles; Optional Treatment Extension Period starting on Day 29 phase 2 : Evaluation of activity and safety in patients with the EGFR T790M mutation
