      Background

      BPI-9016M (Betta Pharmaceuticals Co, Ltd, Hangzhou, China) is a potent targeted therapy that inhibits MET and Axl. This first-in-human study is to assess the safety, tolerability, and pharmacokinetics (PK) of BPI-9016M in patients with advanced solid tumor, and to determine the maximum tolerated dose (MTD) and recommended phase 2 dose (RP2D) for the phase Ib/II study.

      Eligible patients were enrolled into sequential dose-escalating cohorts from 100 mg to 1000 mg given orally once per day continually following the conventional 3+3 design. The primary endpoint was safety and tolerability. MTD was defined as the highest dose level resulting in <1 of 3 dose limiting toxicities (DLTs). Blood levels of BPI-9016M were evaluated after single and multiple administration (NCT02478866).

      Twenty patients were enrolled and treated in 6 of 7 predefined dose cohorts (100 mg n=4, 200 mg n=3, 300 mg n=3, 450 mg n=4, 600 mg n=3, 800 mg n=3), dose escalation stopped at 800 mg due to saturation. All had stage IV non-small cell lung cancer (NSCLC) progressed on previous systemic therapy (including previous EGFR TKI in 16 patients). BPI-9016M was well-tolerated in all dose cohorts without DLT. The incidence of overall and grade 3/4 TRAEs was 85% and 45%, respectively. Common TRAEs included elevated ALT (45%), constipation (30%), elevated bilirubin (25%), and oral paresthesia (25%). Tumor response was seen in 1 patients in the 800 mg dose cohort. Systemic exposure to BPI-9016M (maximum plasma concentration and AUC) increased with increasing dose. Mean time to maximum plasma concentration and half-life were 2 to 5.33 hours and 8.09 to 22.3 hours, respectively. Two metabolites (M1, M2-2) were detected.

      BPI-9016M was well tolerated in patients with advanced solid tumor. A phase Ib study is ongoing to investigate the safety and activity of BPI-9016M in patients with c-Met-dysregulated advanced NSCLC (NCT02929290).
