Comparison of Standard of Care Treatment With a Triplet Combination of Targeted Immunotherapeutic Agents

PRIMARY OBJECTIVE:

I. To assess the efficacy of the combinations durvalumab (MEDI4736) plus olaparib and cediranib, durvalumab (MEDI4736) plus cediranib, or olaparib and cediranib, as measured by progression-free survival (PFS), as compared to physician's choice standard of care chemotherapy, in patients with recurrent platinum-resistant ovarian, primary peritoneal or fallopian tube cancer who had prior bevacizumab.

SECONDARY OBJECTIVES:

I. To assess the efficacy of the combinations durvalumab (MEDI4736) plus olaparib and cediranib, durvalumab (MEDI4736) plus cediranib, or olaparib and cediranib, as measured by overall response rate (ORR) by Response Evaluation Criteria in Solid Tumors (RECIST) version 1.1, as compared to physician's choice standard of care chemotherapy, in patients with recurrent platinum-resistant ovarian, primary peritoneal or fallopian tube cancer who had prior bevacizumab.

II. To assess the efficacy of the combinations durvalumab (MEDI4736) plus olaparib and cediranib, durvalumab (MEDI4736) plus cediranib, or olaparib and cediranib, as measured by overall survival (OS), as compared to physician's choice standard of care chemotherapy, in patients with recurrent platinum-resistant ovarian, primary peritoneal or fallopian tube cancer who had prior bevacizumab.

OUTLINE: Patients are randomized to 1 of 4 arms.

ARM I: Patients receive paclitaxel intravenously (IV) over 60 minutes on days 1, 8, and 15, or pegylated liposomal doxorubicin hydrochloride IV over 60 minutes on day 1, or topotecan hydrochloride IV over 30 minutes on days 1, 8 and 15 or days 1-5 per the discretion of the treating physician. Cycles repeat every 21 or 28 days in the absence of disease progression or unacceptable toxicity. Patients may undergo echocardiography (ECHO) or multigated acquisition scan (MUGA) during screening and as clinically indicated on study. Patients also undergo collection of blood and computed tomography (CT) with contrast during screening, and CT or magnetic resonance imaging (MRI) scans throughout the trial.

ARM II: Patients receive durvalumab IV over 60 minutes on day 1, cediranib maleate orally (PO) once daily (QD) Monday through Friday, and olaparib PO twice daily (BID) on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients may undergo ECHO or MUGA during screening and as clinically indicated on study. Patients also undergo collection of blood and CT with contrast during screening, and CT or MRI scans throughout the trial.

ARM III: Patients receive durvalumab IV over 60 minutes on day 1 and cediranib maleate PO QD Monday through Friday. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients may undergo ECHO or MUGA during screening and as clinically indicated on study. Patients also undergo collection of blood and CT with contrast during screening, and CT or MRI scans throughout the trial.

ARM IV: Patients receive cediranib maleate PO QD on days 1-28 and olaparib PO BID on days 1-28. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Patients may undergo ECHO or MUGA during screening and as clinically indicated on study. Patients also undergo collection of blood and CT with contrast during screening, and CT or MRI scans throughout the trial.

After completion of study treatment, patients are followed up periodically for up to 5 years.
