Brief Title  AG014699 in Treating Patients With Locally Advanced or Metastatic Breast Cancer or Advanced Ovarian Cancer
Official Title  A Cancer Research UK Phase II Proof of Principle Trial of the Activity of the Intravenous PARP-1 Inhibitor, AG-014699, in Known Carriers of a BRCA 1 or BRCA 2 Mutation With Locally Advanced or Metastatic Breast or Advanced Ovarian Cancer
Brief Summary

RATIONALE: AG014699 may stop the growth of tumor cells by blocking some of the enzymes needed for cell growth.

PURPOSE: This phase II trial is studying the side effects and best dose of AG014699 and to see how well it works in treating patients with locally advanced or metastatic breast cancer or advanced ovarian cancer.

Detailed Description

OBJECTIVES:

Primary

  • To determine the response rate to PARP-1 inhibitor AG014699 in patients with locally advanced or metastatic breast or advanced ovarian cancer shown to express the BRCA 1 or 2 mutations.
  • To evaluate the toxicity of this drug in these patients.

Secondary

  • To evaluate the time to progression and overall survival in patients treated with this drug.
  • To study pharmacokinetics of this drug in these patients.
  • To evaluate the Poly(ADP-ribose) polymerase (PARP) activity in peripheral blood lymphocytes from BRCA 1 and 2 heterozygotic patients.

Tertiary

  • To evaluate PARP expression using quantitative western blotting immuno-assays.
  • To investigate pharmacogenomics, including CYP2D6 and CYP3A5, drug transport proteins, as well as polymorphisms in the genes coding for the PARP enzymes themselves.
  • To analyze tumor biopsy samples (when possible) for BRCA mutation status, PARP activity, and PARP expression.
  • To analyze paraffin sections from original diagnostic biopsies/operative procedures (when available) for DNA repair enzyme status using immunohistochemical techniques.
  • To analyze cells obtained from ascitic or pleural fluid (where available) for primary cell culture for DNA double strand break repair pathway function.

OUTLINE: This is a dose-escalation study followed by an open label multicenter study. Patients are stratified according to tumor type (breast vs ovarian) and mutation status ( BRCA 1 vs BRCA 2).

Patients receive PARP-1 inhibitor AG014699 IV (at one of several possible dosages) over 30 minutes once daily on days 1-5. Treatment repeats every 21 days for 12 courses in the absence of disease progression or unacceptable toxicity. Patients who achieve stable or responding disease may receive additional courses of treatment at the discretion of the chief investigator or Drug Development Office (DDO).

Patients undergo blood sample collection periodically for pharmacokinetic and pharmacodynamic studies. Samples are analyzed for tumor marker (CA 125 or CA 15.3) measurements, AG-014699 plasma levels via liquid chromatography/mass spectrometry/mass spectrometry, PARP activity, and PARP protein expression via western blotting immunoassays. Paraffin embedded sections from original diagnostic biopsy are also collected and analyzed for PARP protein expression via immunohistochemical technique. Pleural and ascitic fluid may be collected and analyzed for DNA DS break repair proficiency via immunohistochemical technique. Some patients also undergo biopsy of tumors and samples are analyzed for BRCA 2 mutation as well as PARP activity via validated PARP immunoblotting assay.

After completion of study treatment, patients are followed for 28 days.
