I. To estimate the proportion of patients who have objective tumor response (complete or partial).
II. To determine the frequency and severity of adverse events associated with treatment with veliparib (ABT-888) as assessed by the Active Version of the National Cancer Institute (NCI) Common Terminology Criteria for Adverse Events (CTCAE) version 4.0
I. To determine the duration of progression-free survival (PFS) and overall survival (OS).
II. To determine the proportion of patients who survive progression-free for at least 6 months.
I. To explore the association between single nucleotide polymorphisms (SNPs) in deoxyribonucleic acid (DNA) repair genes (e.g., breast cancer [BRCA]1, Fanconi) and clinical characteristics, response, and patient outcome (PFS and OS).
Patients receive veliparib orally (PO) twice daily (BID) on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
After completion of study treatment, patients are followed up every 3 months for 2 years and then every 6 months for 3 years.

Experimental: Treatment (veliparib)
Patients receive veliparib PO BID on days 1-28. Courses repeat every 28 days in the absence of disease progression or unacceptable toxicity.
Other: Laboratory Biomarker Analysis
- Proportion of Patients With Complete and Partial Tumor Response [ Time Frame: CT scan/MRI if used to follow lesion for measurable disease every other cycle for the first 6 months, then every 3 months until progression. Repeat at other times if clinically indicated.Responses require confirmation at >= 4 wks from first documentation. ]Patients with complete and partial tumor response by RECIST V1.1 (per response evaluation criteria in Solid Tumors Criteria (RECIST V1.1) for target lesions and assessed by MRI (CT scan): Complete Response (CR), disappearance of all target lesions (confirmed at >= 4 weeks); Partial Response (PR) >= 30% decrease in the sum of the longest diameter of target lesions (confirmed at >= 4 weeks); Overall Response = CR + PR.
- Proportion of Patients With Adverse Events as Assessed by CTCAE v4.0 [ Time Frame: After every cycle while on study therapy. Followed for late adverse events up to 30 days after completing therapy. ]Patients with grade 3 or greater Adverse Events (AEs) occurring during treatment and up to 30 days after stopping the study treatment are reported.
- Duration of PFS [ Time Frame: CT scan/MRI if used to follow lesion for measurable disease every other cycle for the first 6 months, then every 3 months until progression. Patients who begin subsequent therapy without progression will be monitored for PFS for 5 years. ]The time from randomization until disease progression, death, or date of last contact. Endpoints are progression or death. Patients who are not observed with an endpoint are censored. Progression is defined using Response Evaluation Criteria in Solid Tumors Criteria (RECIST v1.1), as a 20% increase in the sum of the longest diameter of target lesions (and >= 5 mm increase of target lesions), or a measurable increase in a non-target lesion, or the appearance of new lesions.
- Duration of OS [ Time Frame: Every cycle while patient is receiving protocol therapy. Patients will be monitored for survival after going off therapy for a 5 year period, every 3 months for the first 2 years, then every 6 months for the last 3 years. ]Overall survival
- The Proportion of Patients Who Survive Progression-free for at Least 6 Months [ Time Frame: 6 months ]This outcome captures whether or not the patient survived progression-free for at least 6 months, and is displayed as a proportion.
- SNPs With DNA Repair Genes, Tumor Response, PFS, OS, and Patient Demographics (e.g. Age, Race, Tumor Grade) [ Time Frame: Baseline ]If the clinical trial goes to the second stage and there is sufficient variability in the SNPs, then patients can be categorized by the nature of their SNPs and assessed for prognostic value through survival analysis (e.g. log-rank tests and Cox proportional hazards modeling). If the variability in SNPs is relatively low, assessment of prognostic value can be conducted with odds ratios of patients responding or surviving progression-free for at least 6 months. These techniques will use exact methods such as Fisher's exact test.
- BRCA Mutation in Primary Tumor Tissue [ Time Frame: Baseline ]BRCA mutational status will be tabulated against the germline mutation to see what proportion of patients have a mutation reversal within the tumor and whether such reversals can explain resistance to the regimen under study.
