Phase 1/2 Study of Chemoimmunotherapy With Toll-like Receptor 8 Agonist Motolimod (VTX-2337) + Anti-PD-L1 Antibody MEDI4736 in Subjects With Recurrent, Platinum-Resistant Ovarian Cancer for Whom Pegylated Liposomal Doxorubicin is Indicated
In Brief
A Phase 2 clinical trial evaluating Durvalumab, Pegylated Liposomal Doxorubicin, and 1 other intervention for Ovarian Cancer. Completed, enrolled 53 participants across 5 sites in 2 countries.
Detailed Summary
This is an ongoing Phase 1/2, open-label, multicenter, non-randomized study of MEDI4736 (durvalumab) in subjects with recurrent, platinum-resistant ovarian cancer who are scheduled to receive pegylated liposomal doxorubicin (PLD).The primary objective of Phase 1 is to determine the maximum tolerated dose (MTD) and safety profile, with a secondary objective to evaluate the clinical efficacy as measured by progression-free survival (PFS) rate at 6 months (PFS-6). The primary objective of Phase 2 is the evaluation of clinical efficacy as measured by PFS-6. For both phases, secondary objectives include evaluation of clinical efficacy as measured by overall response rate, PFS, and overall survival (OS), safety and tolerability, and immunological responses.

Timeline
Interventions
Durvalumab is administered as an IV infusion over 60 ± 5 minutes.
PLD was administered as an IV infusion in accordance with local prescribing information.
Motolimod was administered as an SC injection. Within 30 minutes prior to each dose of motolimod, subjects were administered 650-1000 mg acetaminophen by mouth to help mitigate potential adverse events (AEs) commonly associated with the administration of motolimod (e.g., fever, myalgia). On days with concurrent motolimod and durvalumab dosing, motolimod administration occurred 30-60 minutes after the end of the durvalumab infusion. After completion of Phase 1, a protocol amendment was implemented to remove motolimod dosing from the study.
