A Phase 1/2, Study Evaluating the Safety, Tolerability, PK, and Efficacy of Sotorasib (AMG 510) in Subjects With Solid Tumors With a Specific KRAS Mutation (CodeBreaK 100)

Evaluate the safety and tolerability of sotorasib in adult subjects with KRAS p.G12C mutant advanced solid tumors. Estimate the maximum tolerated dose (MTD) and/or a recommended phase 2 dose (RP2D) in adult subjects with KRAS p.G12C mutant advanced solid tumors.

Phase 1 trials primarily test safety and dosing in a small number of participants (typically 20–100). Results do not yet speak to efficacy. FDA approval is typically many years away from this stage.

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.
