Spots Global Cancer Trial Database for Testing the Addition of ASTX660 (Tolinapant) to the Usual Chemotherapy Treatment (Paclitaxel With or Without Bevacizumab) in Patients With Recurrent Ovarian Cancer

Study Description

Brief Summary: This phase I/II trial tests the safety, best dose and effectiveness of adding tolinapant (ASTX660) to paclitaxel with or without bevacizumab in treating patients with ovarian cancer that has come back after a period of improvement (recurrent). Tolinapant may stop the growth of tumor cells by blocking proteins, such as XIAP and cIAP1, that promote the growth of tumor cells and increase resistance to chemotherapy. Paclitaxel is in a class of medications called antimicrotubule agents. It stops tumor cells from growing and dividing and may 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 the tumor. This may slow the growth and spread of tumor cells. Adding ASTX660 to paclitaxel with or without bevacizumab may be safe, tolerable and/or effective in treating patients with recurrent ovarian cancer.

Detailed Description: PRIMARY OBJECTIVES: I. To assess the safety and tolerability of adding ASTX660 (tolinapant) to a regimen of weekly paclitaxel with bevacizumab. (Phase I) II. To determine the recommended phase 2 dose (RP2D) for the combination of ASTX660 (tolinapant) and weekly paclitaxel with bevacizumab. (Phase I) III. To assess the efficacy of adding ASTX660 (tolinapant) to weekly paclitaxel, with or without bevacizumab (investigator choice), as measured by progression free survival (PFS). (Phase II) SECONDARY OBJECTIVES: I. To assess the objective response rate (ORR) of the addition of ASTX660 (tolinapant) to weekly paclitaxel with or without bevacizumab as compared to weekly paclitaxel with or without bevacizumab. II. To assess overall survival. EXPLORATORY OBJECTIVE: I. To explore whether lack of cIAP1 expression results in no benefit for the addition of ASTX660 (tolinapant) to weekly paclitaxel +/- bevacizumab. OUTLINE: This is a phase I, dose escalation study of ASTX660 and paclitaxel with or without bevacizumab followed by a dose expansion study. The phase II study will follow completion of the phase I study. PHASE I: Patients receive paclitaxel intravenously (IV) on days 1, 8 and 15, bevacizumab IV on days 1 and 15, and ASTX660 orally (PO) on days 1-7 and 15-21 of each cycle. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo blood sample collection, computed tomography (CT) and magnetic resonance imaging (MRI) throughout the study. PHASE II: Patients are randomized to 1 of 2 arms. ARM I (CONTROL): Patients receive paclitaxel IV on days 1, 8, and 15 of each cycle. Patients may also receive bevacizumab IV on days 1 and 15 of each cycle per provider. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo blood sample collection, CT and MRI throughout the study. ARM II (EXPERIMENTAL): Patients receive paclitaxel IV on days 1, 8, and 15 and ASTX660 PO on days 1-7 and 15-21 of each cycle. Patients may also receive bevacizumab IV on days 1 and 15 of each cycle per provider. Cycles repeat every 28 days in the absence of disease progression or unacceptable toxicity. Additionally, patients undergo blood sample collection, CT and MRI throughout the study. After completion of study treatment, patients are followed up every 3 months for 2 years then every 6 months for 3 years.
