This is an expanded access protocol to allow continued maintenance therapy with ABT-888 (veliparib) for three patients with metastatic triple negative breast cancer who are currently receiving the investigational product in association with clinical trial participation. Additionally, the protocol will enroll up to 7 new patients with metastatic BRCA associated or triple negative breast cancer to allow for additional access to veliparib monotherapy, or at the investigator's discretion, veliparib in combination with cisplatin and/or vinorelbine.

Detailed Description:

ABT-888 (Veliparib) or Poly(ADP-ribose)-polymerase (PARP) is a nuclear enzyme that recognizes deoxyribonucleic acid (DNA) damage and facilitates DNA repair. Inactive PARPs 1 and 2 bind to damaged DNA, which leads to their auto-activation. The resulting activated PARP then poly(ADP-ribosyl)ates many nuclear target proteins, including those that facilitate DNA repair of both single-stranded or double-stranded DNA breaks. Thus, PARP inhibition will result in less efficient DNA repair following a DNA damage insult.

Since cancer cells are genetically unstable, often exhibiting complex karyotypes that include large deletions, insertions, and unbalanced translocations of chromosomal fragment, these cells are more susceptible than normal tissues to cytotoxicity induced by DNA-damaging agents.Of these, deficiencies in mismatch repair and homologous recombination are associated with the largest number of malignancies, including many sporadic TNBCs. These deficiencies render cells more dependent on PARP for DNA repair and, hence, are more prone to cytotoxicity induced by PARP inhibition. In particular, tumor cells with BRCA1 or BRCA2 deficiencies are exquisitely sensitive to PARP inhibition, even in the absence of any other insults. Identification of sporadic TNBC with defects in homologous recombination and mismatch repair independent of germline mutation of BRCA 1 and 2 is an active area of research interest.

PARP-enabled DNA repair may also compensate for the loss of other repair pathways. Higher expression of PARP in cancer cells compared to normal cells has been linked to drug resistance and the overall ability of cancer cells to sustain genotoxic stress.

The combination of platinum based chemotherapy and PARP inhibition may be most effective in TNBC, and particularly in subsets of TNBC. This combination may also be active in tumors with a germline BRCA1-deficiency and/or basal phenotype, since a defect in the DNA double-strand break repair pathway should increase sensitivity to these agents. The addition of a PARP inhibitor to platinum based chemotherapy may induce a "double hit" to tumor cells lacking homologous recombination without causing excess toxicity to normal cells. ABT-888 may be used in combination with the DNA damaging agent, cisplatin, to potentiate its cytotoxic effect and with vinorelbine to enhance tumor response rate. Safety and preliminary efficacy of veliparib in combination with cisplatin and vinorelbine in patients with advanced triple negative and BRCA-associated breast cancer has been reported.

  1. Inclusion Criteria Roll-over patients: This protocol allows for the inclusion of 3 patients actively participating in protocol 7161 who are expected to continue to benefit from uninterrupted dosing of veliparib monotherapy.

    For newly enrolled patients the following criteria should be satisfied within 28 days of Day 1 of protocol treatment. Results from routine clinical evaluations within 28 days prior to enrollment may be used to determine eligibility:

    • Hepatic function: AST and/or ALT < 2.5 × the upper normal limit of institution's normal range.

      o For patients with liver metastases, AST and/or ALT < 5 × the upper normal limit of institution's normal range;

    • Bilirubin < 1.5 × the upper normal limit of institution's normal range;

      o Patients with Gilbert's Syndrome may have a bilirubin > 1.5 × the upper normal limit of institution's normal range.

Women of childbearing potential must have a negative serum pregnancy test within 21 days prior to initiation of treatment and/or be confirmed as having postmenopausal status. Criteria for determining menopause include any of the following: prior bilateral oopherectomy; age > 60 years; age < 60 years and amenorrheic for at least 12 months in the absence of chemotherapy, endocrine therapy, or ovarian suppression and FSH and estradiol in the postmenopausal range.
    • Total abstinence from sexual intercourse (minimum one complete menstrual cycle);
    • Vasectomized partner of female patients;

    • Additionally, male patients (including those who are vasectomized) whose partners are pregnant or might be pregnant must agree to use condoms for the duration of the treatment plan and for 90 days following completions of therapy.
    • Radiation therapy must have been completed at least 2 weeks prior to the enrollment date.
    • Patients with known brain metastases must have clinically controlled neurologic symptoms, defined as surgical excision and/or radiation therapy followed by 14 days of stable neurologic function prior to the first dose of study drug.
    • Ability to understand and the willingness to sign a written informed consent document.

    • Symptomatic congestive heart failure;
    • Unstable angina pectoris or cardiac arrhythmia;

    • Myelodysplastic syndrome;
    • History of seizures within last 12 months or known neurological disorder pre-disposing to seizures
    • Patient is pregnant or lactating.
