Summary
Brief summary (as posted)
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.

- Cohort A Monotherapy Dose Escalation
- description
- 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
- description
- 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.
