Complete list of historical versions of study NCT01351909 on ClinicalTrials.gov Archive Site
  • Clinical response (complete or partial response) according to RECIST version 1.1 [ Time Frame: Up to 24 weeks ] [ Designated as safety issue: No ]
    Clinical response and benefit rates in each group will be estimated by computing proportions and corresponding 95% confidence intervals. Rates will be compared between groups using the Fisher's exact test.
  • MacroH2A1.1 expression levels [ Time Frame: Up to 6 years ] [ Designated as safety issue: No ]
    Expression levels of macroH2A1.1 will be compared between patients with and without clinical benefit using the two-sample T-test or Wilcoxon rank sum test, depending on the distribution of the data. Logistic regression models will also be fit to the data to adjust for potential confounders in the analysis.
  • Overall survival [ Time Frame: Time from treatment initiation to death, assessed up to 6 years ] [ Designated as safety issue: No ]
    Overall survival will be analyzed using standard survival analytic approaches including the Kaplan-Meier method and the log-rank test.
  • PARP1 expression status [ Time Frame: Up to 6 years ] [ Designated as safety issue: No ]
    Expression levels of PARP1 will be compared between patients with and without clinical benefit using the two-sample T-test or Wilcoxon rank sum test, depending on the distribution of the data. Logistic regression models will also be fit to the data to adjust for potential confounders in the analysis.

Cyclophosphamide and Veliparib in Treating Patients With Locally Advanced or Metastatic Breast Cancer
Phase I Trial of Low-Dose Cyclophosphamide in Combination With Veliparib (ABT-888) in HER2/Neu-Negative Metastatic Breast Cancer

This phase I trial studies the side effects and best dose of cyclophosphamide and veliparib when given together in treating patients with breast cancer that has spread from where it started to nearby tissue or lymph nodes or to other places in the body. Drugs used in chemotherapy, such as cyclophosphamide, 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. Veliparib may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth. Giving cyclophosphamide together with veliparib may work better in treating breast cancer.

PRIMARY OBJECTIVES:

I. To determine the recommended phase II dose of veliparib (ABT-888) that can be combined with metronomic dose cyclophosphamide in patients with metastatic breast cancer.

SECONDARY OBJECTIVES:

I. To determine whether the macroH2A1.1 and poly (adenosine diphosphate [ADP]-ribose) polymerase 1 (PARP1) expression status in archival paraffin embedded tumor specimens from either the primary tumor or metastatic disease is predictive of clinical benefit with veliparib (ABT-888) plus cyclophosphamide.

OUTLINE: This is a dose-escalation study.

Patients receive veliparib orally (PO) once daily (QD) and cyclophosphamide PO QD on days 1-21. Courses repeat every 21 days in the absence of disease progression or unacceptable toxicity.

After completion of study treatment, patients are followed up periodically.

Inclusion Criteria:

  • Phase I: Patients must have histologically confirmed breast cancer (metastatic breast cancer [MBC]) that is human epidermal growth factor receptor 2 (HER2/neu) negative (as determined by local pathology or reference laboratory), and have disease that is metastatic (stage IV [TxNxM1]) or locally advanced and not amenable to potentially curative surgical resection (eg, clinical stage IIIB-C)
  • HER2/neu negative disease (performed on primary tumor and/or metastatic lesion using commercially available/approved assay in local institutional or reference laboratory), according to American Society of Clinical Oncology (ASCO)/College of American Pathologists (CAP) guidelines
  • National Comprehensive Cancer Network (NCCN) guidelines recommend for metastatic breast cancer "…biopsy documentation of first recurrence, if possible, and determination of hormone receptor status (estrogen receptor [ER] and progesterone receptor [PR]) and HER2 status…."; therefore, histologic and/or cytologic confirmation of metastatic disease is encouraged whenever feasible, but not required; in some circumstances, histologic confirmation may not be feasible (eg, bone metastases not amenable to biopsy and elevated cancer antigen [CA]27-29 tumor marker); for patients who have had histologic confirmation of metastatic disease, it is required that the biopsy confirm that the metastatic tumor is ER and/or PR positive, and HER2/neu negative; for patients in whom biopsy confirmation of metastatic disease is not feasible, it is required that the primary tumor be ER and/or PR-positive and HER2/neu negative
  • Measurable disease (Response Evaluation Criteria in Solid Tumors [RECIST] 1.1) or non-measurable disease, with measurement obtained within 4 weeks of registration
  • Phase I: Patients must have received at least one prior chemotherapy regimen for metastatic disease; patients with deleterious germ line mutations in breast cancer (BRCA)1 or BRCA2 are not required to have received prior chemotherapy for metastatic disease
  • Patients must have had progressive disease after at least one line of endocrine therapy for metastatic disease (includes relapse while receiving endocrine therapy); there should be at least 1 week interval between the last endocrine treatment for an aromatase inhibitor and at least 2 weeks for tamoxifen or fulvestrant

  • Patients must be able to swallow whole capsules and tolerate oral medications
  • 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; being not of childbearing potential is defined as: (1) prior hysterectomy, or (2) no menstrual period for at least 24 months; should a woman become pregnant or suspect she is pregnant while participating in this study, she should inform her treating physician immediately
