NCT03848845: Phase 1/2: Study Evaluating Safety, Tolerability and Clinical Activity of GSK2857916 in Combination With Pembrolizumab in Subjects With Relapsed/Refractory Multiple Myeloma (RRMM) (DREAMM 4)

Study Evaluating Safety, Tolerability and Clinical Activity of GSK2857916 in Combination With Pembrolizumab in Subjects With Relapsed/Refractory Multiple Myeloma (RRMM) (DREAMM 4)

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).
