NCT ID: NCT02036502

Last Updated: 2021-04-08

Basic Information

• Recruitment Status: TERMINATED
• Clinical Phase: PHASE1
• Total Enrollment: 77 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2014-02-14
• Study Completion Date: 2020-03-19

Brief Summary

This is a study of pembrolizumab (MK-3475) in combination with lenalidomide and low-dose dexamethasone in participants with refractory or relapsed and refractory Multiple Myeloma (rrMM), and in combination with carfilzomib and low-dose dexamethasone in participants with relapsed or refractory Multiple Myeloma (rMM).

This study was being done to find the maximum tolerated dose (MTD)/maximum administered dose (MAD) and recommended Phase 2 dose (RP2D), and to evaluate the safety and tolerability of pembrolizumab when given in combination with standard of care (SOC) treatments in participants with rrMM or rMM. Preliminary efficacy data will also be assessed. There was no primary hypothesis associated with this study.

On 03-Jul-2017, the United States Food and Drug Administration (US FDA) placed the rrMM cohort of this protocol on clinical hold based on safety data from two other pembrolizumab protocols: MK-3475-183 (NCT02576977) and MK-3475-185 (NCT02579863) presented to the Data Monitoring Committee.

On 15-Sep-2017, the US FDA placed the rMM cohort of this study on partial clinical hold. Enrollment was stopped and will not be reopened. Participants who are deriving clinical benefit were allowed to continue receiving study treatment until protocol-specific end of treatment, and then progress into long term safety and survival follow up. Participants who are not deriving clinical benefit, must stop study treatment and move into the long term safety and survival follow up.
