Official title
A Phase 1 Study of MK-5890 as Monotherapy and in Combination With Pembrolizumab in Participants With Advanced Solid Tumors
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The purpose of this study is to assess the safety and pharmacokinetics of boserolimab (MK-5890) when administered alone and in combination with pembrolizumab (MK-3475) in adults. Boserolimab monotherapy or boserolimab plus pembrolizumab combination therapy will be administered in adults with advanced solid tumors, including endometrial cancer, for up to 35 administrations (approximately 2 years). The safety and pharmacokinetics of boserolimab when administered with pembrolizumab, pemetrexed and carboplatin in adults with non-squamous non-small cell lung cancer (NSCLC) and boserolimab when administered with pembrolizumab and nab-paclitaxel in adults with triple-negative breast cancer (TNBC) will also be assessed.
