The main aim of this study is to: * evaluate safety and efficacy (per Response Evaluation Criteria in Solid Tumors version 1.1 \[RECIST 1.1\] by investigator) of 2 dose levels of tarlatamab for Part 1 only * evaluate anti-tumor activity of tarlatamab as determined by objective response rate (ORR) per RECIST 1.1 by blinded independent central review (BICR) for Part 1 and 2 * evaluate safety of reduced mandatory monitoring period in Cycle 1 at selected dose of tarlatamab for Part 3
Phase 2 trials begin testing efficacy in a larger patient group (100–300). This is often where biotech binary events occur — positive Phase 2 data can significantly advance a company's pipeline narrative, while failures can be terminal for a program.
Enrollment is complete. The trial is in its follow-up or data collection phase — a readout may occur on or near the primary completion date.
Amgen Inc (AMGN) is the sponsoring company for this trial. BiotechSign currently grades this company F (35/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
