Sacituzumab Govitecan With Bevacizumab Compared to Usual Chemotherapy (Carboplatin, Pegylated Liposomal Doxorubicin and Bevacizumab) for Treating Recurrent Platinum-Sensitive Ovarian Cancer After PARP Inhibitor Maintenance Therapy
A Randomized Phase II Trial of Sacituzumab Govitecan (SG) and Bevacizumab Versus Standard of Care Carboplatin, Pegylated Liposomal Doxorubicin (PLD) and Bevacizumab in Patients With Platinum-Sensitive Ovarian Cancer That Has Progressed on Prior Maintenance PARP Inhibitor Therapy

Brief Summary
This phase II trial compares the effect of sacituzumab govitecan and bevacizumab to standard care (carboplatin, pegylated liposomal doxorubicin, and bevacizumab) in patients with ovarian cancer that has come back after an initial response to platinum therapy (platinum-sensitive), that has progressed after poly (adenosine diphosphate-ribose) polymerase (PARP) inhibitor maintenance therapy (recurrent), and that has a mutation in the BRCA1 or BRCA2 genes or is homologous recombination deficient. Sacituzumab govitecan is a monoclonal antibody, called sacituzumab, linked to a drug called govitecan. Sacituzumab is a form of targeted therapy because it attaches to specific molecules (receptors) on the surface of cancer cells, known as TROP2 receptors, and delivers govitecan to kill them. Bevacizumab is in a class of medications called antiangiogenic agents. It works by stopping the formation of blood vessels that bring oxygen and nutrients to tumor. This may slow the growth and spread of tumor cells. Carboplatin is in a class of medications known as platinum-containing compounds. Carboplatin works by killing, stopping or slowing the growth of cancer cells. Doxorubicin is in a class of medications called anthracyclines. Doxorubicin damages the cell's deoxyribonucleic acid (DNA) and may kill cancer cells. It also blocks a certain enzyme needed for cell division and DNA repair. Liposomal doxorubicin is a form of the anticancer drug doxorubicin that is contained inside very tiny, fat-like particles. Liposomal doxorubicin may have fewer side effects and work better than other forms of the drug. Giving sacituzumab govitecan and bevacizumab may kill more tumor cells than standard care (carboplatin, pegylated liposomal doxorubicin, and bevacizumab) in patients with recurrent platinum-sensitive ovarian cancers that have BRCA1/2 mutations or homologous recombination deficiency.

Conditions
Outcome Measures
Primary Outcomes (1)
Progression-free survival
The primary analysis will compare progression-free survival between Arm II and Arm I using a stratified log-rank test. The corresponding hazard ratio will be estimated from a stratified Cox regression model. The treatment hazard ratio estimate and its 95% confidence interval will be estimated using proportional hazards models specified to be consistent with the logrank tests.
From randomization to either progressive disease or death from any cause, assessed up to 5 years
Secondary Outcomes (3)
Objective response rate (ORR)
Within 12 months of starting maintenance therapy
Duration of response (DOR)
From the first documented response (CR or PR) until disease progression or death, assessed up to 5 years
Incidence of adverse events
Up to 5 years
Other Outcomes (4)
TROP2 expression
Up to 5 years
Cell-free deoxyribonucleic acid (cfDNA)
Up to 5 years
Time to first subsequent therapy or death (TFST)
From randomization to the earliest occurrence of either first subsequent therapy or death, assessed up to 5 years
- +1 more other outcomes
Study Arms (2)
Arm I (carboplatin, PLD, bevacizumab)
ACTIVE COMPARATORPatients receive carboplatin IV on day 1, PLD IV on day 1 (or gemcitabine IV on days 1 and 8), and bevacizumab (or anti-VEGF antibody biosimilar) IV on days 1 and 15 of each cycle. Cycles repeat every 21 days for 6-10 cycles in the absence of disease progression or unacceptable toxicity. After 6-10 cycles, patients proceed to maintenance therapy. MAINTENANCE: Patients receive bevacizumab (or anti-VEGF antibody biosimilar) IV on day 1 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients also undergo ECHO at screening and undergo CT and/or MRI and collection of blood samples throughout the trial.
Arm II (SG, bevacizumab)
EXPERIMENTALPatients receive SG IV on days 1 and 8 and bevacizumab (or anti-VEGF antibody biosimilar) IV on day 1 of each cycle. Cycles repeat every 21 days for 6-10 cycles in the absence of disease progression or unacceptable toxicity. After 6-10 cycles, patients proceed to maintenance therapy. MAINTENANCE: Patients receive bevacizumab (or anti-VEGF antibody biosimilar) IV on day 1 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT and/or MRI and collection of blood samples throughout the trial.

Eligibility Criteria
You may qualify if:

- Ovarian cancer = fallopian tube, ovarian, and primary peritoneal cancer
- Disease must be platinum sensitive, as defined by progression documented ≥ 6 months (182 days) from the last receipt of platinum
- Disease must have progressed during first line maintenance PARP inhibitor (PARPi) for advanced ovarian cancer. NO intervening therapies between progression on PARPi and study registration are permitted
- Disease must be germline or somatic BRCA1 or BRCA2 mutated or homologous recombination deficiency test positive
- Disease must be measurable or assessable as defined by Response Evaluation Criteria in Solid Tumors (RECIST) version (v.) 1.1
- Patients with treated brain metastases are eligible if follow up brain imaging 4 weeks after central nervous system (CNS) directed therapy shows no evidence of progression
- Secondary or cytoreductive surgery, after start of treatment on this trial, and prior to documentation of disease progression, is NOT permitted
- No previous receipt of any topoisomerase-I inhibiting agents
- No investigational agents within 4 weeks of study registration
- No current treatment with any other (non-study) cytotoxic chemotherapy, targeted therapy, biologic therapy, immunotherapy or endocrine therapy for the treatment of the disease under the current study
- Last dose of PARP inhibitor treatment must be ≥ 3 weeks before study registration
- Patients with treated brain metastases are eligible if follow-up brain imaging after CNS-directed therapy shows no evidence of disease progression. Patients with brain metastases must have follow up imaging demonstrating no evidence of disease progression and that the disease is stable off of steroids
- Age ≥ 18
- Eastern Cooperative Oncology Group (ECOG) performance status of ≤ 2
- +21 more criteria
