Brief 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.
Detailed Description:
In the completed Phase 1 part of the study, eligible subjects were enrolled using a standard 3 + 3 design to identify the MTD (i.e., the highest dose for which fewer than 33% of subjects experienced a dose-limiting toxicity \[DLT\]) of combination study treatment. All dose levels in Phase 1 included intravenous (IV) PLD (40 mg/m\^2) in combination with subcutaneous (SC) motolimod (2.0 or 2.5 mg/m\^2), using a starting dose of 3 mg/kg of IV durvalumab given every 2 weeks (Q2W) or 1500 mg of IV durvalumab given every 4 weeks (Q4W). All subjects in a cohort had their safety data reviewed for DLTs before proceeding with cohort expansion.
After completion of Phase 1 and determination of the durvalumab MTD to be carried forward into Phase 2, availability of data from another study (NCT01666444) indicated a lack of additive efficacy when motolimod was administered with PLD compared with PLD alone. As such, motolimod dosing was discontinued for all subjects in Study LUD2014-001 after completion of Phase 1. Subjects who had initiated treatment may have continued to receive PLD and durvalumab at their respective dose levels but must have discontinued motolimod. Thus, in the fully-accrued but ongoing Phase 2 portion of the study, subjects received only PLD (40 mg/m\^2) in combination with durvalumab at the MTD determined in Phase 1 (1500 mg every 4 weeks \[Q4W\]).
Subjects are treated in the Core Study for an initial 12 cycles (28 days each) according to their treatment assignment. Durvalumab treatment may be extended for subjects who complete the Core Study with stable disease or better and upon agreement among the subject, Sponsor, and Investigator; extended durvalumab monotherapy may continue until confirmed disease progression, unacceptable toxicity, withdrawal of consent, or other discontinuation criteria are met.
Subjects are followed on study for 90 days after the last drug administration and off study every 3 months for 3 years from the date of the first dose of study treatment.
