Ovarian Cancer Clinical Trial
Durvalumab and Tremelimumab in Treating Participants With Recurrent or Refractory Ovarian, Primary Peritoneal, or Fallopian Tube Cancer
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.
I. To determine the median immune-related progression-free survival (irPFS) in the experimental arms.
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 overall survival (OS), objective response rate (ORR) IV. To determine the proportion of patients that discontinue treatment due to side effects.
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. To better assess the relationship between somatic tumor mutations in the PPP2R1A gene and response and survival following combination therapy with tremelimumab and durvalumab in two molecularly defined expansion cohorts: (a) subjects with ovarian clear cell carcinoma and (b) subjects with uterine serous carcinoma. (This objective will represent an expansion cohort in Arm 2 and will be independent of enrollment to the main study)
OUTLINE: Participants are randomized to 1 of 2 arms.
ARM I (SEQUENTIAL): Patients receive tremelimumab intravenously (IV) over 60 minutes on day 1. Treatment repeats every 4 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. Upon progression, patients then receive durvalumab IV over 60 minutes on day 1. Treatment repeats every 4 weeks for up to 9 cycles in the absence of disease progression or unacceptable toxicity. This arm is closed to enrollment.
ARM II (COMBINATION): Patients receive tremelimumab IV and durvalumab IV over 60 minutes (for each drug) on day 1. Treatment repeats every 4 weeks for 4 cycles in the absence of disease progression or unacceptable toxicity. Patients then receive durvalumab IV over 60 minutes on day 1. Treatment repeats every 4 weeks for up to 9 cycles in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up at 30 days and then every 2 months thereafter

Age >/= 18 years at time of study entry.
Eastern Cooperative Oncology Group (ECOG) performance status of 0 or 1.
Adequate normal organ and marrow function as defined by: Hemoglobin >/= 9.0 g/dL (transfusion is allowed to correct anemia); Absolute neutrophil count (ANC) >/= 1.5 x 10^9/L (> 1500 per mm^3); Platelet count >/= 100 x 10^9/L (>100,000 per mm^3); Serum bilirubin = 1.5 x institutional upper limit of normal (ULN) unless diagnosed with Gilbert's syndrome; AST and ALT = 2.5 x ULN unless liver metastases are present, in which case it must be = 5x ULN; Serum creatinine CL >40 mL/min by the Cockcroft-Gault formula ( Cockcroft and Gault 1976) or by 24-hour urine collection for determination of creatinine clearance: Creatinine CL (mL/min) = [Weight (kg) x (140 - Age) x 0.85]/[72 x serum creatinine (mg/dL)].
Subjects must either be of non-reproductive potential (i.e., post-menopausal by history: >/= 60 years old and no menses for >/= 1 year without an alternative medical cause; OR history of hysterectomy, OR history of bilateral tubal ligation, OR history of bilateral oophorectomy) or must have a negative serum pregnancy test upon study entry.
Subject is willing and able to comply with the protocol for the duration of the study including undergoing treatment and scheduled visits and examinations including biopsies and follow up.
Histology (reviewed at MDACC) showing recurrent high grade epithelial ovarian, peritoneal, or fallopian tube cancer of clear cell histology or mixed carcinoma with a clear cell component. In addition, subjects for the molecularly defined expansion cohort will also include patients with recurrent uterine serous carcinoma (who have received at least one prior line of platinum-based chemotherapy), and must have somatic mutations testing (performed by MD Anderson or a CLIA certified test offered by a commercial vendor such as Foundation One or Caris) that demonstrates a nonsynonymous PPP2R1A mutation (other protein phosphatase 2A or related pathway mutations/alterations may be eligible if approved by the PI). Synonymous mutations and variants of uncertain significance do not qualify.
Platinum resistant or refractory disease as defined by progression of disease on a platinum-containing regimen or recurrence of disease within 180 days of previous platinum treatment (not applicable to the uterine serous carcinoma molecularly defined expansion cohort, however, subjects with uterine serous must have received at least one prior line of platinum-based therapy).
Have measurable disease based on modified RECIST 1.1. 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, CT, and 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.

(If sufficient wash-out time has not occurred due to the schedule or PK properties of an agent, a longer wash-out period may be required.)
