This study will evaluate the efficacy and safety of olaparib (MK-7339) monotherapy in participants with multiple types of advanced cancer (unresectable and/or metastatic) that: 1) have progressed or been intolerant to standard of care therapy; and 2) are positive for homologous recombination repair mutation (HRRm) or homologous recombination deficiency (HRD).
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.
Merck & Co (MRK) 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.
