Brief Summary:
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 with advanced solid tumors. The initial course of boserolimab monotherapy or boserolimab plus pembrolizumab combination therapy will be 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.

Condition or disease Intervention/treatment Phase
Pharmacokinetics Solid Tumor Carcinoma, Non-Small-Cell Lung Triple Negative Breast Neoplasms Drug: Boserolimab Biological: Pembrolizumab Drug: Pemetrexed Drug: Carboplatin Drug: Nab-paclitaxel Phase 1

Detailed Description:
Participants receiving boserolimab monotherapy who experience disease progression may be eligible to switch to receiving boserolimab plus pembrolizumab combination therapy for up to 35 cycles (approximately 2 years) at the discretion of the Investigator and approval of the Sponsor.
