The purpose of this study is to assess the efficacy and safety of treatment with olaparib (MK-7339) in combination with pembrolizumab (MK-3475) in adults with previously treated, advanced (metastatic and/or unresectable) Homologous Recombination Repair Mutation (HRRm) and/or Homologous Recombination Deficiency (HRD)-positive solid tumors.
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.
