Study of MK-4830 as Monotherapy and in Combination With Pembrolizumab (MK-3475) in Participants With Advanced Solid Tumors (MK-4830-001)

Summary

This study consists of several parts: dose escalation, dose expansion, dose expansion in Chinese participants residing in China, and coformulation. Dose escalation is to evaluate the safety, tolerability, and preliminary efficacy of MK-4830 monotherapy administration (Arms A and B) and in combination with pembrolizumab (Arm C). Dose expansion is to evaluate the objective response rate (ORR) of MK-4830 in combination with pembrolizumab (Arms A-F); evaluate the safety and tolerability of MK-4830 administered in combination with pembrolizumab, carboplatin, and pemetrexed (Arm G) and of MK-4830 administered in combination with pembrolizumab and lenvatinib (Arm H); evaluate the safety, tolerability and ORR of MK-4830 in combination with pembrolizumab plus chemotherapy (Arms I-L); and evaluate the safety and tolerability of MK-4830 in combination with pembrolizumab in Chinese participants from China (Arm M). The coformulation part (Arm N) evaluates the safety and tolerability of MK-4830A (coformulation of MK-4830 800 mg + pembrolizumab 200 mg). There is no formal hypothesis testing in this study.

Conditions

• Neoplasms

Interventions

DRUG

MK-4830

MK-4830 will be administered intravenously (IV) Q3W. In Part C, MK-4830 will be administered after completion of pembrolizumab infusion. Dose escalation will proceed based on emerging safety and tolerability data of MK-4830 as monotherapy (Part A and B) and as combination therapy with pembrolizumab (Part C). For each dose level, an assessment will be made of the safety and tolerability data in order to define the next dose level to be tested.

DRUG

Pembrolizumab

Pembrolizumab will be administered at 200 mg IV Q3W.

DRUG

Carboplatin

Carboplatin will be administered IV Q3W.

DRUG

Pemetrexed

Pemetrexed will be administered IV Q3W.

DRUG

Lenvatinib

Lenvatinib will be administered orally once daily.

DRUG

Paclitaxel

Paclitaxel will be administered IV QW on Days 1, 8, and 15 of each 21-day cycle until disease progression or prohibitive toxicity (Arm J) and on Days 1, 8, and 15 Q4W until disease progression or prohibitive toxicity (Arm K).

DRUG

Cisplatin

Cisplatin will be administered IV Q3W.

BIOLOGICAL

MK-4830A

MK-4830A, a coformulation of MK-4830 800 mg + pembrolizumab 200 mg, will be administered IV Q3W.
