Study of MK-7684 Alone and in Combination With Pembrolizumab in Advanced Solid Tumors (MK-7684-001)

NCT02964013

Description:

This is a safety, efficacy, and pharmacokinetics (PK) study of 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 MK-7684 monotherapy or in combination with pembrolizumab, pemetrexed, and carboplatin. Part A will also evaluate the anti-tumor activity of MK-7684 in combination with pembrolizumab plus pemetrexed and carboplatin in participants with non-small cell lung cancer (NSCLC) and MK-7684 (at two dose levels) in combination with pembrolizumab in Japanese participants with gastric cancer. Part B will evaluate the anti-tumor activity of MK-7684 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 MK-7684 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 MK-7684A, a co-formulated product of MK-7684 plus pembrolizumab, to MK-7684 in combination with pembrolizumab administered as separate intravenous infusions. The primary hypotheses are that MK-7684 administered as monotherapy or in combination with pembrolizumab is safe and tolerable when administered at the RPTD and that MK-7684A is safe and tolerable when administered as a fixed dose.

NameTypeDescriptionInterventions
MK-7684ExperimentalDuring an initial dose evaluation phase, participants will receive Dose A, B, C, D, E, or F of MK-7684 on Day 1 of each 21-day infusion cycle (for a maximum of 35 cycles) until the RPTD has been established. The RPTD will be established based on the number of dose limiting toxicities (DLTs) at each dose level. Once the RPTD is established, participants will continue receiving the RPTD of MK-7684 on Day 1 of each 21-day infusion cycle until the 35-cycle limit is reached.

MK-7684+pembrolizumab (pembro)ExperimentalDuring an initial dose evaluation phase, participants will receive Dose A, B, C, D, E, or F of MK-7684 in combination with 200 mg pembrolizumab on Day 1 of each 21-day infusion cycle (for a maximum of 35 cycles) until the RPTD of MK-7684 has been established. The RPTD will be established based on the number of DLTs at each dose level. Once the RPTD of MK-7684 is established, participants will continue receiving the RPTD of MK-7684 in combination with 200 mg pembrolizumab on Day 1 of each 21-day infusion cycle until the 35-cycle limit is reached.
