* Has received previous treatment with another agent targeting the T cell immunoglobulin and immunoreceptor tyrosine-based inhibitory motif (TIGIT) receptor
* Has received previous treatment with an immunomodulatory agent (e.g., anti-programmed cell death 1, anti-programmed cell death ligand 1 or cytotoxic T-lymphocyte-associated protein 4) and was discontinued from that treatment due to a Grade 3 or higher immune-related adverse event
* Is expected to require any other form of antineoplastic therapy while participating in the trial
* Is on chronic systemic steroid therapy in excess of replacement doses or on any other form of immunosuppressive medication

* Has previously had a hematopoetic stem cell transplant or solid organ transplant
* Is known to be human immunodeficiency virus (HIV) positive and/or known to have active chronic or acute Hepatitis B or Hepatitis C
* Has a known psychiatric and/or substance abuse disorder that would make it difficult for the participant to cooperate with the requirements of the trial
* Is a regular user (including recreational use) of any illicit drugs at the time of providing documented informed consent, or has a recent history (within the last year) of substance abuse
* Has received a live virus vaccine within 30 days prior to the first dose of study treatment
* Has had hormonal cancer therapy (e.g., tamoxifen, leuprolide). within 4 weeks prior to the first dose of study treatment
* For Part A participants with NSCLC added with Amendment 7: Is unable to interrupt aspirin or other nonsteroidal anti-inflammatory drugs (NSAIDs) other than an aspirin dose =1.3 gram per day for a 5-day period (8-day period for long-acting agents, such as piroxicam)

Summary
Brief summary
This is a safety, efficacy, and pharmacokinetics (PK) study of vibostolimab (MK-7684) as monotherapy and in combination with pembrolizumab (MK-3475) or pembrolizumab plus pemetrexed and carboplatin in adults with metastatic solid tumors for which there is no available therapy that is expected to convey clinical benefit. Part A of this study is a dose escalation and confirmation phase to estimate the recommended Phase 2 dose (RPTD) for vibostolimab monotherapy or in combination with pembrolizumab, pemetrexed, and carboplatin. Part A will also evaluate the anti-tumor activity of vibostolimab in combination with pembrolizumab plus pemetrexed and carboplatin in participants with non-small cell lung cancer (NSCLC) and vibostolimab (at two dose levels) in combination with pembrolizumab in Japanese participants with gastric cancer. Part B will evaluate the anti-tumor activity of vibostolimab at the RPTD when used as monotherapy and in combination with pembrolizumab in participants with advanced solid tumors in a non-randomized study design. Part B will also evaluate 2 doses of vibostolimab in combination with pembrolizumab in participants with programmed death 1 (PD-1) treatment naïve cancer using a 1:1 randomized study design. Part B is expanded with Amendment 11 to include an additional arm that will compare the safety and PK of a fixed dose of pembrolizumab/vibostolimab coformulation (MK-7684A) to vibostolimab in combination with pembrolizumab administered as separate intravenous infusions. Part A is expanded with Amendment 12 to include an additional arm that will compare the safety and PK of vibostolimab plus pembrolizumab plus the investigator's choice of platinum agent (carboplatin or cisplatin), and etoposide. Part B is expanded with Amendment 12 to include evaluation of efficacy of vibostolimab plus pembrolizumab plus the investigator's choice of platinum agent (carboplatin or cisplatin), and etoposide and efficacy of pembrolizumab/vibostolimab coformulation in participants from mainland China. The primary hypotheses are that vibostolimab administered as monotherapy or in combination with pembrolizumab is safe and tolerable when administered at the RPTD and that pembrolizumab/vibostolimab coformulation is safe and tolerable when administered as a fixed dose.
