The purpose of this study is to assess the safety and pharmacokinetics of MK-5890 when administered alone and in combination with pembrolizumab (MK-3475) in adults with advanced solid tumors. The initial course of MK-5890 monotherapy or MK-5890 plus pembrolizumab combination therapy will be for up to 35 administrations (approximately 2 years). The safety and pharmacokinetics of MK-5890 when administered with pembrolizumab, pemetrexed and carboplatin in adults with nonsquamous non-small cell lung cancer (NSCLC) and MK-5890 when administered with pembrolizumab and nab-paclitaxel in adults with triple-negative breast cancer (TNBC) will also be assessed.


Participants receiving MK-5890 monotherapy who experience disease progression may be eligible to switch to receiving MK-5890 plus pembrolizumab combination therapy for up to 35 cycles (approximately 2 years) at the discretion of the Investigator and approval of the Sponsor.

Adequate organ function
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1
Male participants must agree to use adequate contraception during the treatment period and for at least 120 days after the last dose of MK-5890 or pembrolizumab OR 180 days after the last dose of chemotherapeutic agents and refrain from donating sperm during this period
Submit an evaluable baseline tumor sample for analysis (either a newly obtained or archival tumor sample)
Female participants must not be pregnant or breastfeeding and agree to follow use adequate contraception during the treatment period and for at least 120 days after the last dose of MK-5890 or pembrolizumab OR 180 days after the last dose of chemotherapeutic agents
