This is a Phase 1/1b open-label study evaluating the safety, pharmacokinetics (PK), and preliminary efficacy of ABBV-399 as monotherapy and in combination with osimertinib, erlotinib, and nivolumab in participants with advanced solid tumors likely to express c-Met. Enrollment is closed for the monotherapy arms, Arm A, and Arm D.
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.
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.
AbbVie Inc (ABBV) is the sponsoring company for this trial. BiotechSign currently grades this company C (58/100) based on composite catalyst signals across its full pipeline. This trial is one data point in that overall catalyst picture.
