- Brief Summary
The purpose of this study is to evaluate the safety and tolerability of humanized IgG4 (kappa) isotype monoclonal antibody against CEACAM1 (CM-24 \[MK-6018\]), administered intravenously as monotherapy and in combination with Pembrolizumab (MK-3475), in participants with selected advanced or recurrent malignancies. Escalating multiple doses will be evaluated to determine the recommended dose for Phase 2 clinical studies.

Group Intervention Description Cohort C1 Combination Expansion Pembrolizumab (MK-3475) Participants with advanced or recurrent cutaneous melanoma will be enrolled and treated at the recommended phase 2 dose of CM-24+ 200 mg of Pembrolizumab for up to 17 cycles and may continue to receive 200 mg of Pembrolizumab as monotherapy for up to an additional 18 cycles (up to 35 total cycles). Cohort B Combination Dose Escalation CM-24 (MK-6018) Participants will be enrolled at the recommended phase 2 dose (RP2D) of CM-24 (MK-6018), determined by escalation studies, minus 1 dose level of MK-6018 in combination with a fixed dose of 200 mg pembrolizumab. Participants will be escalated to the RP2D of MK-6018 + 200 mg pembrolizumab. If the RP2D of MK-6018 + 200 mg pembrolizumab is not tolerated, the dose of MK-6018 will be de-escalated but will not fall below 1 mg/kg. Participants will be treated for 6 weeks during Cycle 1 and 2. Afterwards participants with clinical benefit and no DLTs are treated for up to 35 cycles. Cohort E Monotherapy Expansion CM-24 (MK-6018) Participants with advanced or recurrent gastric cancer will be enrolled and treated at the recommended phase 2 dose of CM-24 (MK-6018) for up to 17 cycles. Cohort F Combination Expansion CM-24 (MK-6018) Participants with advanced or recurrent non-small cell lung adenocarcinoma will be enrolled and treated at the recommended phase 2 dose of CM-24+ 200 mg of Pembrolizumab for up to 17 cycles and may continue to receive 200 mg of Pembrolizumab as monotherapy for up to an additional 18 cycles (up to 35 total cycles).

Cohort A Monotherapy Dose Escalation CM-24 (MK-6018) Participants will be enrolled in a staggered manner starting at a dose of 0.01 mg/kg of CM-24 (MK-6018) and continuing to 0.03, 0.1, 0.3, 1.0, 3.0, and 10 mg/kg to determine the recommended Phase 2 dose (RP2D). The dose will be escalated after a 6- to 8-week DLT window. Participants will be treated for 12 weeks during Cycle 1. Afterwards participants with clinical benefit and no dose-limiting toxicites (DLTs) are treated for up to 6 cycles. Cohort B Combination Dose Escalation Pembrolizumab (MK-3475) Participants will be enrolled at the recommended phase 2 dose (RP2D) of CM-24 (MK-6018), determined by escalation studies, minus 1 dose level of MK-6018 in combination with a fixed dose of 200 mg pembrolizumab. Participants will be escalated to the RP2D of MK-6018 + 200 mg pembrolizumab.
