Design outcomes

Primary

MeasureTime frame
Main Objective: Phase 1b: •To observe the safety and tolerability of bemarituzumab Phase 2: •To evaluate preliminary antitumor activity;Secondary Objective: Phase 1b: •To evaluate other measures of preliminary antitumor activity •Characterize the PK of bemarituzumab monotherapy Phase 2: •To evaluate other measures of preliminary antitumor activity •To evaluate the safety and tolerability of bemarituzumab •Characterize the PK of bemarituzumab monotherapy;Primary end point(s): Phase 1: •Dose-limiting toxicities (DLTs), treatment-emergent adverse events, treatment-related adverse events, and clinically significant changes in vital signs, visual acuity, and clinical laboratory tests Phase 2: •Objective Response (OR);Timepoint(s) of evaluation of this end point: Endpoints to be assessed throughout the course of the study. (See Table 1-1 in section 1.3 Schedule of Activities in Protocol)

Secondary

MeasureTime frame
Secondary end point(s): Phase 1 and Phase 2: Objective response (OR) •Disease control (DC) (CR, PR, or stable disease [SD]) •Duration of response (DOR) •Time to response (TTR) •Progression-free survival (PFS) •Overall survival (OS) •PK parameters for bemarituzumab including, but not limited to, AUC, Cmax, and Ctrough •PK parameters for bemarituzumab including, but not limited to, area under the concentration time curve (AUC), maximum observed concentration (Cmax), and the observed concentration at the end of a dose interval (Ctrough);Timepoint(s) of evaluation of this end point: OR, DC, DOR, TTR, PFS: •Radiographic assessment to be performed every 8 weeks (± 7 days) until week 56 and then every 12 weeks (± 14 days) until radiographic progression or initiation of subsequent anticancer therapy. OS: •To be assessed after subject enrollment and throughout the course of the study. After safety follow-up subjects will undergo long term follow-up for survival approximately every 3 months (± 1 month) for up to 2 years from the first dose of bemarituzumab. (See Table 1-1 in section 1.3 Schedule of Activities in Protocol)
