A Study of BGB324 (Bemcentinib) in Combination With Erlotinib in Patients With Non-Small Cell Lung Cancer

This is a multi-center, multi-arm open-label Phase 1/2 study that was conducted at 10 clinical sites in the United States and in Europe. Total 40 participants with histologically- or cytologically-confirmed Stage IIIb or Stage IV NSCLC received bemcentinib (BGB324) as a single agent (Run-in Cohort) or in combination with erlotinib (Arms A, B, and C). Run-in Arm to establish the safety and tolerability of bemcentinib (BGB324) administered as a single agent; bemcentinib was administered at a loading dose of 600 mg on Day 1 and Day 2 of Cycle 1, followed by 200 mg daily thereafter. After 6 participants have been dosed and safety established; Arm A (dose escalation arm) was opened to confirm the bemcentinib dose to be used in combination with erlotinib. In Arm A the dose of bemcentinib (BGB324) was escalated in a standard 3+3 fashion until a maximum tolerated dose (MTD) of the combination (bemcentinib + erlotinib) was established. The dose of bemcentinib to be investigated in Arm B and C was confirmed upon recommendation of a Safety Review Committee. Arm B and C was open in parallel to investigate bemcentinib in combination with erlotinib.
