a phase ii study of nivolumab/ bevacizumab/rucaparib

Conditions: Peritoneal Cancer; Ovarian Cancer; Fallopian Tube Cancer

Summary: this research study is evaluating three drugs called nivolumab, bevacizumab, and rucaparib as a possible treatment for relapsed relapsed ovarian, fallopian tube or peritoneal cancer.

this research study is a phase ii clinical trial. cancers are recognized by the immune system, and under some circumstances,the immune system may control or even eliminate tumors. an antibody is a natural protein made by our immune system that binds other proteins and molecules to fight infection and its ill effects. nivolumab is an experimental antibody drug that may make the immune response more active against cancer. bevacizumab is an antibody that works by stopping the formation of blood vessels.rucaparib is an oral pill that can block the ways cells repair their dna, which can cause damage to certain cancer cells. the fda (the u.s. food and drug administration) has not approved nivolumab for relapsed ovarian, fallopian tube or peritoneal cancer but it has been approved for other uses. bevacizumab has been fda approved when used together with chemotherapy for the treatment of ovarian, fallopian tube, or primary peritoneal cancer that has returned within 6 months of a chemotherapy that contains a platinum drug. rucaparib has been fda approved for the treatment of patients with brca-mutated ovarian cancer who have been treated with 2 or more prior chemotherapies or as maintenance therapy following for women with platinum-sensitive recurrent ovarian cancer. the combination of nivolumab, bevacizumab, and rucaparib has not been approved by the fda in any setting.

Eligibility criteria:
inclusion criteria: * participants must have histologic or cytologic confirmation of epithelial ovarian cancer, fallopian tube or peritoneal cancer. all histologies (including serous, mucinous, endometrioid, clear cell, mmmts, and mixed histologies) are eligible. all tumor grades are eligible. * participants must have received a first-line platinum-based chemotherapy regimen * participants must have relapsed disease despite standard therapy. * for cohorts 1 and 2: participants with platinum-resistant or platinum-sensitive disease (within 12 months) are eligible. platinum-resistant disease is defined as relapse within 6 months after the last dose of platinum-based chemotherapy. platinum-sensitive disease is defined as relapse greater than 6 months after the last dose of platinum-based chemotherapy. participants with platinum-sensitive disease who have experienced relapse within 6 to 12 months after the last dose of platinum-based chemotherapy are eligible.participants with primary platinum-refractory disease (defined as progression during or relapsed within 2 months of their initial platinum-based chemotherapy) are not eligible. for cohort 3: participants must have platinum-sensitive disease and have experienced relapse within 6 to 12 months (i.e., 180 to 365 days) after the last dose of platinum-based chemotherapy. * participants must have received no more than 3 prior chemotherapy regimens. there is no limit to the number of prior hormonal therapies. * participants must have measurable disease by recist 1.1 criteria. * participants who have received prior bevacizumab are eligible unless there is evidence of unacceptable toxicity due to prior bevacizumab exposure. * participants may not have received any prior treatment with an anti-pd-1, anti pd-l1, anti-pd-l2, anti-ctla-4 antibody, or any other antibody or drug specifically targeting t-cell co-stimulation or immune checkpoint pathways. * participants must have stopped any hormonal therapy at least 1 week prior to treatment with nivolumab and bevacizumab.participants may continue on hormone replacement therapy administered for post-menopausal symptoms.
