About this study

Official title: Phase II Trial of Single Agent ABT-888 With Post-Progression Therapy of ABT-888 in Combination With Carboplatin in Patients With Stage IV BRCA-Associated Breast Cancer

This phase II trial studies how well veliparib with or without carboplatin works in treating patients with stage III or IV breast cancer. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Drugs used in chemotherapy, such as carboplatin, 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. It is not yet known whether veliparib is more effective with or without carboplatin in treating breast cancer.

Read the detailed description

PRIMARY OBJECTIVE:

  1. To evaluate the efficacy of single agent veliparib (ABT-888) (NSC 737664) in breast cancer (BRCA) carriers with metastatic breast cancer based on response rate (Response Evaluation Criteria In Solid Tumors [RECIST] criteria).

SECONDARY OBJECTIVES:

  1. To conduct subset analysis on BRCA1 versus (vs.) BRCA2 and hormone receptor status.

II. To evaluate progression-free survival of patients on single-agent ABT-888. III. To further describe the safety and tolerability of ABT-888 (NSC 737664) as a single agent and in combination with carboplatin for BRCA-associated breast cancer.

IV. To evaluate the pharmacokinetics of ABT-888 (NSC 737664) alone and in combination with carboplatin.

  1. To assess the relationship between the level of poly adenosine diphosphate (ADP) ribose polymerase (PARP) inhibition by ABT-888 and biomarkers of deoxyribonucleic acid (DNA) damage in peripheral blood mononuclear cell (PBMC's) and in tumor.

VI. To explore the relationship between biomarkers of drug effect and progression-free survival.

VII. To evaluate the efficacy and safety of the combination of carboplatin and ABT-888 in patients who have failed single agent ABT-888.

VIII. To conduct subset analysis on BRCA1 vs. BRCA2 and hormone receptor status.

OUTLINE: This is a dose-escalation study of veliparib. Patients are assigned to 1 of 2 phases.

SAFETY LEAD-IN PHASE: Patients receive veliparib orally (PO) twice daily (BID) on days 1-21 of each cycle and carboplatin intravenously (IV) over 30 minutes on day 1 of each cycle. Cycles repeats every 21 days in the absence of disease progression or unacceptable toxicity. Patients also undergo computed tomography (CT) or magnetic resonance imaging (MRI) and may optionally undergo biopsies throughout the study. Patients undergo blood sample collection during screening and on study.

PHASE II: Patients receive veliparib PO BID on days 1-21 of each cycle. Cycles repeat every 21 days in the absence of disease progression or unacceptable toxicity. Upon progression, patients are taken off treatment for 1 week and may then continue to recieve veliparib along with carboplatin IV over 30 minutes on day 1 of each cycle. Cycles repeats every 21 days in the absence of disease progression or unacceptable toxicity. Patients also undergo CT or MRI and may optionally undergo biopsies throughout the study. Patients undergo blood sample collection during screening and on study.

  • As of the November 9, 2023 amendment, the pharmaceutical collaborator has discontinued the ABT-888 development program with the National Cancer Institute Cancer Therapy Evaluation Program (CTEP). Clinical supply will no longer be available after December 31, 2024. Patients will discontinue treatment by December 31, 2024, or earlier.

After completion of study treatment, patients are followed up every 6 months.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Number of Subject With Overall Response

    Per Response Evaluation Criteria In Solid Tumors Criteria (RECIST v1.1) for target lesions and assessed by MRI: Complete Response (CR), Disappearance of all target lesions. Any pathological lymph nodes (whether target or nontarget) must have reduction in short axis to <10 mm; Partial Response (PR), at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum diameters; Overall Response (OR) = CR + PR

    Measured: Up to 8 weeks post-treatment

  2. Progression-free Survival

    Progression-free survival will be summarized as time from first protocol treatment until progression or death from any cause, using the product-limit Kaplan-Meier estimator. Progression is defined using Response Evaluation Criteria In Solid Tumors Criteria (RECISTv1.1), as at least a 20% increase in the sum of diameters of target lesions, taking as reference the smallest sum on study (this includes the baseline sum if that is the smallest on study). In addition to the relative increase of 20%, the sum must also demonstrate an absolute increase of at least 5 mm. (Note: the appearance of one or more new lesions is also considered progression).

    Measured: From start of treatment to time of progression or death from any cause, whichever occurs first, assessed up to at least 1 year

Secondary outcomes (3)

  1. Maximum Tolerated Dose (MTD)

    The maximum tolerated dose of veliparib in combination with AUC 5 of Carboplatin is based on toxicities observed during the first cycle and is defined as the highest dose tested in which fewer than 33% of patients experience an attributable DLT to the study drug, when at least 6 patients are treated at that dose and are evaluable for toxicity. Dose escalations proceeded according to a standard 3+3 design.

    Measured: 21 days from start of treatment, up to 2 years

  2. Number of Participants With at Least One Dose Limiting Toxicity (DLT) - Phase I

    Dose-limiting toxicity will be graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0. Pre-specified DLT criteria included the following adverse events (AE), judged to be at least possibly related to study therapy: any grade III non-hematological toxicity not reversible to grade II or less within 96 hours, or any grade IV toxicity (excluding alopecia or controllable nausea and vomiting). Additionally, patients unable to take 80% of the planned ABT-888 due to toxicity/tolerability will be considered to have had a DLT.

    Measured: During the first cycle of treatment, up to 21 days

  3. Overall Survival

    Overall survival will be summarized as time from first protocol treatment until death from any cause, using the product-limit Kaplan-Meier estimator.

    Measured: From start of treatment to time of death from any cause, assessed up to at least 3 years
