GSK Clinical Trials

This is a phase I/II, single arm, open label, two-part study that will assess safety, tolerability and clinical activity of GSK2857916 given in combination with a programmed cell death-1 (PD-1) inhibitor pembrolizumab in subjects with RRMM. This study will enroll adult subjects with RRMM, who have undergone stem cell transplant or who are considered transplant ineligible. Part 1 is a dose escalation phase to evaluate the safety and tolerability of escalating doses of GSK2857916 in combination with 200 milligrams (mg) pembrolizumab to establish the recommended phase 2 dose (RP2D). The following dose levels of GSK2857916 are planned to be studied: 2.5 milligrams per kilograms (mg/kg) (dose level \[DL\] 1) and 3.4 mg/kg (DL2). Part 2 is a dose expansion cohort. Once the RP2D has been identified, an expansion cohort will open for enrolment to confirm the safety profile and to evaluate the clinical activity of the combination. Up to 40 evaluable subjects will be enrolled in this two-part study (up to 12 in Part 1, and 28 in Part 2).

Subjects will receive GSK2857916 at escalating doses along with pembrolizumab on Day 1 of each 21-day Cycle to establish RP2D during the Part 1 of the study. Subjects will receive GSK2857916 at RP2D along with pembrolizumab on Day 1 of each 21-day Cycle in Part 2 of the study.

This will be an open-label study. Hence, there will be no masking.
