CB-839 in Combination With Niraparib in Platinum Resistant BRCA -Wild-type Ovarian Cancer Patients (BRCA)
November 17, 2023 updated by: Rebecca Arend, University of Alabama at Birmingham
Phase 1 Trial of CB-839 in Combination With Niraparib in Platinum Resistant BRCA-wild-type Ovarian Cancer Patients
The purpose of this protocol is to investigate the efficacy of the combination of CB-839 with Niraparib in platinum resistant BRCA wild-type ovarian cancer patients.
The primary and secondary objectives are to determine the maximum tolerated dose of CB-839 in combination with Niraparib and to determine the response rate and percentage of participants who remain progression free at 6 months.

Intervention / Treatment
Detailed Description
Based on the scientific rationale, pre-clinical data, and clinical data available to date, and the need for further treatment options in patients that are platinum resistance that are specifically BRCA wild-type.
Only patients carrying wild type BRCA genes will be enrolled in the study.
The proposed research tests a new therapeutic strategy for ovarian cancer with a very novel mechanistic target: metabolic dependency of ovarian cancer.
Pre-clinical results indicate that both serous and clear cells ovarian cancers have upregulation of Hypoxia Inducible Factors (HIF) HIF1a and Hypoxia Inducible Factors (HIF) HIF2a regulated genes.
In addition, cell line models of these tumors display sensitivity to CB-839 in vitro.
Ovarian cancers resistant to standard platinum chemotherapy may thus respond to treatment with this glutaminase inhibitor.
The majority of patients do not present mutations in BRCA or any other genes of the Fanconi pathway, but their tumors may respond to CB-839, which in turn may lead to genomic instabilities due to nucleotide deprivation; therefore, CB-839 could sensitize the tumors to treatment with Niraparib.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Experimental: Cohort 1: Dose Escalation using Niraparib and CB-839
The first phase will be a 3+3 design, 3 participants will be enrolled in the first cohort with a fixed dose of Niraparib and CB-839, 600 mg.
If there are no dose limiting toxicities (DLT), 3 additional participants will be enrolled in the next cohort (CB-839, 800mg).
If 1 of the 3 in the first cohort experiences DLT's, then the additional participants will be enrolled in the same cohort (CB-839, 600mg).
|
The first 3 participants will be enrolled on a fixed dose of Niraparib and CB-839, 600mg.
Participants will be evaluated for DLT's, if there are none, they will be enrolled in the next cohort.

Experimental: Cohort 2: Dose Escalation using Niraparib and CB-839
If there are no DLT's, 3 additional participants will be enrolled in the next cohort with a fixed dose of Niraparib and CB-839, 800mg.
|
If no dose limiting toxicities, 3 additional participants will be enrolled in this cohort.
Participants will receive a fixed dose of Niraparib and CB-839, 800mg.
Other Names:
|
Experimental: Cohort 3: Expansion with Maximum Tolerated Dose (MTD)
Patients in this expansion cohort will continue study treatment with the MTD until they experience disease progression, unacceptable toxicity or withdraw consent.
Patients who discontinue study treatment for reasons other than Progressive-Free Survival (PFS) will continue to have PFS follow-up visits every 2 months for the first 6 months after treatment, and every 3 months until disease progression, death, or start of another anticancer therapy.
|
If no dose limiting toxicities, 3 additional participants will be enrolled in this cohort.
Participants will receive a fixed dose of Niraparib and CB-839, 800mg.
