Veliparib and Carboplatin in Treating Patients With HER2-Negative Metastatic Breast Cancer

Running, not enrolling · Phase 1

Conditions studied: Recurrent Breast Carcinoma, Stage IIIB Breast Cancer AJCC v7, Stage IIIC Breast Cancer AJCC v7, Stage IV Breast Cancer AJCC v6 and v7, Triple-Negative Breast Carcinoma

In brief

This phase I trial studies the side effects and best dose of veliparib when given together with carboplatin and to see how well they work in treating patients with human epidermal growth factor 2 (HER2)-negative breast cancer that has spread to other parts of the body. Carboplatin kills cancer cells by damaging the deoxyribonucleic acid (DNA) that lets the cancer cell survive and reproduce. The body has proteins that try to repair the damaged DNA. Veliparib may prevent these proteins from repairing the DNA so that carboplatin may be able to kill more tumor cells. Giving veliparib with carboplatin may kill more tumor cells than carboplatin alone.

You may qualify if…

• Patients must have histologically or cytologically proven metastatic or locally advanced inoperable breast cancer that fulfills one of the following two criteria:
• Triple-negative breast cancer
• ER and/or PR positive, HER2 negative if their tumors have been shown to be deficient for the FA pathway, based on FA triple stain immunofluorescence (FATSI) screening
• HER negative with a known germline BRCA1/2 mutation
• Patients with ER- and/or PR-positive breast cancer will be consented to have their existing, or to be obtained, paraffin-embedded tumor tissue screened for FA deficiency
• No more than 3 prior chemotherapy regimens for metastatic disease will be allowed; any number of prior hormone therapies will be allowed; however, at least 4 weeks should have elapsed since prior chemotherapy (6 weeks for mitomycin C and nitrosoureas and 2 weeks for hormone therapy) or radiation therapy (2 weeks for limited field palliative radiation to the bone)
• Eastern Cooperative Oncology Group (ECOG) performance status =< 2 (Karnofsky >= 60%)
• Patients with treated brain metastases and life expectancy of greater than 3 months
• Patients with known Gilbert syndrome with abnormal unconjugated bilirubin will be eligible
• Absolute neutrophil count >= 1,500/mcL
• Platelets >= 100,000/mcL
• Total bilirubin within normal institutional limits
• Aspartate aminotransferase (AST) (serum glutamic oxaloacetic acid transaminase [SGOT])/alanine aminotransferase (ALT) (serum glutamate pyruvate transaminase [SGPT]) =< 2.5 X institutional upper limit of normal
• Creatinine within normal institutional limits OR creatinine clearance >= 60 mL/min/1.73 m\^2 for patients with creatinine levels above institutional normal
• No prior therapy with veliparib for metastatic disease will be allowed
• Women of child-bearing potential and men must agree to use adequate contraception (hormonal or barrier method of birth control; abstinence) prior to study entry and for the duration of study participation; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
• Ability to understand and the willingness to sign a written informed consent document
• Patients must be able to swallow pills

You may not qualify if…

• Patients who have had chemotherapy or radiotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to entering the study or those who have not recovered from adverse events due to agents administered more than 4 weeks earlier
• Patients may not be receiving any other investigational agents
• History of allergic reactions attributed to compounds of similar chemical or biologic composition to veliparib or other agents used in study
• Uncontrolled intercurrent illness including, but not limited to, ongoing or active infection, symptomatic congestive heart failure, unstable angina pectoris, cardiac arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• Pregnant women are excluded from this study; breastfeeding should be discontinued if the mother is treated with veliparib
• Known human immunodeficiency virus (HIV)-infected patients on protease inhibitors are ineligible; HIV-infected patients with adequate cluster of differentiation (CD)4 counts (> 500) and not on protease inhibitors are eligible
• Patients with active seizure or a history of seizures are not eligible
• Patients with uncontrolled central nervous system (CNS) metastasis are not eligible; patients with CNS metastases must be stable after therapy for > 3 months and off steroid treatment prior to study enrollment
