This phase II trial studies how well durvalumab and tremelimumab work in treating participants with ovarian, primary peritoneal, or fallopian tube cancer that has come back or does not respond to treatment. Immunotherapy with monoclonal antibodies, such as durvalumab and tremelimumab, may help the body's immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. It is not yet known whether give durvalumab and tremelimumab in combination or sequential administration works better in treating participants with ovarian, primary peritoneal, or fallopian tube cancer.

Study summary:

PRIMARY OBJECTIVES: I. To determine the median immune-related progression-free survival (irPFS) in the experimental arms. SECONDARY OBJECTIVES: I. To determine the rate of grade III or higher treatment related toxicity in each experimental arm. II. To describe the immunological and gene expression changes induced by tremelimumab and the combination of tremelimumab and durvalumab in epithelial ovarian cancer (EOC) tumor tissues and blood. III. To determine the median overall survival (OS), objective response rate (ORR), and irPFS rate at 10 months. IV. To determine the proportion of patients that discontinue treatment due to side effects. EXPLORATORY OBJECTIVES: I. To determine second progression-free survival (PFS) (PFS2) following initial progression in each arm. II. To determine the response rate to durvalumab (MEDI4736) following treatment with tremelimumab (in the sequential arm). III. To evaluate the patient reported symptom burden in each experimental arm. OUTLINE: Participants are randomized to 1 of 2 arms. ARM I (SEQUENTIAL): Participants receive tremelimumab intravenously (IV) over 60 minutes on day 1. Treatment repeats every 4 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. Participants then receive durvalumab IV over 60 minutes on day 1. Treatment repeats every 4 weeks for 9 courses in the absence of disease progression or unacceptable toxicity. ARM II (COMBINATION): Participants receive tremelimumab IV and durvalumab IV over 60 minutes on day 1. Treatment repeats every 4 weeks for 4 courses in the absence of disease progression or unacceptable toxicity. Participants then receive durvalumab IV on day 1. Treatment repeats every 4 weeks for 9 courses in the absence of disease progression or unacceptable toxicity. After study treatment, participants are followed up at 30 days and then every 2 months thereafter.

For the purposes of this study measurable disease is defined at least one "target" lesion that can be accurately measured in at least one dimension (longest dimension to be recorded). Each target lesion must be > 20 mm when measured by conventional techniques, including palpation, plain x-ray, computed tomography (CT), and magnetic resonance imaging (MRI), or > 10 mm when measured by spiral CT. The target lesion must be distinct from other tumor areas selected for pre-treatment biopsies. Pre-treatment imaging must be performed within 4 weeks of starting therapy. Exclusion Criteria: - Involvement in the planning and/or conduct of the study (applies to both AstraZeneca staff and/or staff at the study site). - Previous enrollment or randomization in the present study. - Participation in another clinical study with an investigational product administered during the last 28 days. - Any previous treatment with adoptive T cells therapy, a PD1 or PDL1 inhibitor, including durvalumab or any anti-CTLA4 therapy, including tremelimumab. - History of another primary malignancy except for: malignancy treated with curative intent and with no known active disease >= 5 years before the first dose of study drug and of low potential risk for recurrence; adequately treated non-melanoma skin cancer or lentigo maligna without evidence of disease; or adequately treated carcinoma in situ without evidence of disease, e.g., cervical cancer in situ. - Receipt of the last dose of anti-cancer therapy (chemotherapy, immunotherapy, endocrine therapy, targeted therapy, biologic therapy, tumor embolization, monoclonal antibodies, other investigational agent) =< 28 days prior to the first dose of study drug (=< 21 days prior to the first dose of study drug for subjects who have received prior tyrosine kinase inhibitors [TKIs] [e.g., erlotinib, gefitinib and crizotinib] and =< 6 weeks for nitrosourea, mitomycin C, or bevacizumab). (If sufficient wash-out time has not occurred due to the schedule or pharmacokinetics [PK] properties of an agent, a longer wash-out period may be required.) - Mean QT interval corrected for heart rate (QTc) >= 470 ms calculated from 3 electrocardiograms (ECGs) using Fridericia's correction. - Current or prior use of immunosuppressive medication within 28 days before the first dose of durvalumab OR tremelimumab, with the exceptions of intranasal and inhaled corticosteroids or systemic corticosteroids at physiological doses, which are not to exceed 10 mg/day of prednisone, or an equivalent corticosteroid. Steroid premedication for the prevention of radiologic contrast hypersensitivity is allowed. - Any unresolved toxicity (> Common Terminology Criteria for Adverse Events [CTCAE] grade 1) from previous anti-cancer therapy, excluding alopecia. Subjects with irreversible toxicity greater than grade 1 that is not reasonably expected to be exacerbated by the investigational product may be included (e.g., hearing loss, peripherally neuropathy). - Any prior grade >= 3 immune-related adverse event (irAE) while receiving any previous immunotherapy agent, or any unresolved irAE > grade 1. - Active or prior documented autoimmune disease within the past 2 years.
