Summary

This phase II/III trial studies how well pegylated liposomal doxorubicin hydrochloride with atezolizumab and/or bevacizumab work in treating patients with ovarian, fallopian tube, or primary peritoneal cancer that has come back (recurrent). Chemotherapy drugs, such as pegylated liposomal doxorubicin hydrochloride, work in different ways to stop the growth of tumor cells, either by killing the cells, by stopping them from dividing, or by stopping them from spreading. Immunotherapy with monoclonal antibodies, such as atezolizumab, may help the body’s immune system attack the cancer, and may interfere with the ability of tumor cells to grow and spread. Bevacizumab is a monoclonal antibody that may interfere with the ability of tumor cells to grow and spread. It is not yet known which combination will work better in treating patients with ovarian, fallopian tube, or primary peritoneal cancer.

Objectives

PRIMARY OBJECTIVES:
I. Estimate the probability of a dose limiting toxicity (DLT) following cycle 1 of experimental regimens (pegylated liposomal doxorubicin hydrochloride [pegylated liposomal doxorubicin] [PLD] and atezolizumab and PLD/bevacizumab and atezolizumab). (Safety lead-in)
II. Estimate and compare the hazard of first progression or death (progression free survival [PFS]) of each experimental regimen relative to the reference regimen, PLD and bevacizumab. (Phase II study)
III. Estimate and compare the hazard of death and the hazard of first progression or death (PFS) of the experimental regimen relative to the reference regimen. (Phase III) (24-FEB-2021)

SECONDARY OBJECTIVES:
I. Estimate and compare the probabilities of response (objective response rate [ORR], either partial or complete response) defined by Response Evaluation Criteria in Solid Tumors (RECIST) version (v)1.1 criteria on each study regimen. (Phase II study) (24-FEB-2021)
II. Estimate the frequency and severity of adverse events as classified and graded with Common Terminology Criteria for Adverse Events (CTCAE) in those patients who initiate their randomly assigned study treatment. (Phase II study) (03/19/2018)
III. Estimate and compare ORR in each treatment group. (Phase III study)
IV. Estimate the frequency and severity of adverse events in those patients who initiate their randomly assigned study treatment. (Phase III study)
V. Estimate and compare mean patient reported outcome scores (PROs) as measured by National Comprehensive Cancer Network (NCCN)-Functional Assessment of Cancer Therapy (FACT) ovarian symptom index (NFOSI)-18 disease-related symptoms (DRS). (Phase III study)
VI. Estimate and compare the treatment groups on the basis of the PROs: treatment side effects (TSE), function/well-being (FWB), fatigue (Functional Assessment of Chronic Illness Therapy [FACIT]-fatigue subscale) and abdominal discomfort (FACT/Gynecologic Oncology Group [GOG]-abdominal discomfort [AD] subscale). (Phase III study) (10/16/2017)

TRANSLATIONAL SCIENCE OBJECTIVES:
I. To determine whether biomarker levels in pre-treatment tissue, and pre- or on-treatment peripheral blood, and stool specimens are associated with ORR, PFS and/or overall survival (OS).
II. Estimate pre-treatment PD-L1 expression on tumor cells measured by quantitative immunohistochemistry (IHC), and determine whether it is associated with the duration of PFS or overall survival. (Integrated Biomarker)
III. Analysis of T cell receptor (TCR) repertoires by deep sequencing of peripheral blood samples. (Exploratory Biomarkers [10/16/2017])
IV. Tumor “immunogenicity” as determined by the neo-antigen landscape and characterization of the tumor microenvironment using next-generation sequencing, including but not limited to whole exome sequencing and/or RNA sequencing. (Exploratory Biomarkers [10/16/2017])
V. Microbiome analysis via stool sampling. (Exploratory Biomarkers [10/16/2017])
VI. To determine whether changes in quantitative biomarker parameters after the first 6 and 12 weeks of therapy predict ORR, PFS and/or OS.

OUTLINE: Patients will be randomized to 1 of 3 arms.

ARM I: Patients receive pegylated liposomal doxorubicin hydrochloride intravenously (IV) over 60 minutes on day 1 and atezolizumab IV over 30-60 minutes on days 1 and 15. (Closed to accrual as of February 09, 2021)

ARM II: Patients receive pegylated liposomal doxorubicin hydrochloride IV over 60 minutes on day 1, bevacizumab IV over 30-90 minutes on days 1 and 15, and atezolizumab IV over 30-60 minutes on days 1 and 15. Patients also undergo computed tomography (CT) on study.

ARM III: Patients receive pegylated liposomal doxorubicin hydrochloride IV over 60 minutes on day 1 and bevacizumab IV over 30-90 minutes on days 1 and 15. Patients also undergo CT on study.

In all arms, cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up every 3 months for up to 2 years, and then every 6 months for up to 3 years.

Eligibility

1. Patients must have the psychological ability and general health that permits completion of the study requirements and required follow up
2. Administration of study drugs (pegylated liposomal doxorubicin, bevacizumab, atezolizumab) may have an adverse effect on pregnancy and poses a risk to the human fetus, including embryo-lethality; women of child-bearing potential (WOCBP) must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry, for the duration of study participation, and for 5 months (150 days) after the last dose of study agent; should a woman become pregnant or suspect she is pregnant while she is participating in this study, she should inform her treating physician immediately. (06/29/2017)
3. Submission of tumor tissue is required for all patients; investigators should check with their site pathology department regarding release of biospecimens before approaching patients about participation in the trial
4. High grade ovarian cancer, including high grade serous; clear cell; endometrioid, grade 3; and others (adenocarcinoma, not otherwise specified [NOS]; mixed epithelial carcinoma; undifferentiated carcinoma); NOTE: low grade serous, mucinous and carcinosarcoma histologies are excluded due to their different underlying genomic features and/or clinical behavior; ovarian cancer = ovarian, fallopian tube or primary peritoneal cancer; required data element: submission of pathology report
5. Recurrent, platinum resistant ovarian cancer (defined as progression within < 6 months from completion of platinum based therapy; the date should be calculated from the last administered dose of platinum therapy)
6. 1-2 prior regimens (including primary therapy); hormonal therapies (e.g., tamoxifen, aromatase inhibitors) will not count toward the prior regimen limit; PARP inhibitors given in the maintenance setting post response to platinum-based therapy will not count as a separate regimen from the preceding platinum-based therapy. (30-OCT-2020)
7. Measurable disease (defined by RECIST v1.1) or evaluable disease (defined as solid and/or cystic abnormalities on radiographic imaging that do not meet RECIST 1.1 definitions for target lesions OR ascites and/or pleural effusion that has been pathologically demonstrated to be disease related in the setting of cancer antigen [CA] 125 >= 2 x upper limit of normal [ULN])
8. Age >= 18
9. Performance status 0, 1 or 2
10. Absolute neutrophil count (ANC) >= 1,500/mcl (within 14 days prior to registration)
11. Platelets >= 100,000/mcl (within 14 days prior to registration)
12. Hemoglobin (Hgb) >= 8 g/dl (within 14 days prior to registration)
13. Creatinine =< 1.5 x institutional upper limit of normal (ULN) (within 14 days prior to registration)
14. Urine protein creatinine (UPC) ratio must be < 1.0 (within 14 days prior to registration); if UPC ratio >= 1, collection of 24-hour urine measurement of urine protein is recommended (24-hour urine protein level must be < 1000 mg for patient enrollment); If UPC ratio cannot be calculated because the urine protein is below the lower limit of detection of the assay this will not exclude the patient (10/22/2018) (30-OCT-2020); UPC ratio of spot urine is an estimation of the 24-hour urine protein excretion - a UPC ratio of 1 is roughly equivalent to a 24-hour urine protein of 1 gm
