Brief Summary:
This randomized trial studies transdermal or oral telapristone acetate in treating patients undergoing surgery to remove the breast (mastectomy). Telapristone acetate may help prevent breast cancer from forming in premenopausal women. Giving telapristone acetate transdermally may be safer and have fewer side effects than oral administration.

Detailed Description:

PRIMARY OBJECTIVES:

I. To demonstrate that mean levels of telapristone (telapristone acetate) in breast tissue following gel application will result in levels that are not more than 50% lower than those following oral administration.

SECONDARY OBJECTIVES:

I. To assess whether plasma concentrations of telapristone are significantly lower with transdermal than oral therapy.

II. To compare within-breast variation of breast tissue concentration in transdermal and oral groups.

III. To measure changes in cell proliferation (marker of proliferation Ki-67 [Ki67] labeling index) and apoptosis (terminal deoxynucleotidyl transferase deoxyuridine triphosphate [dUTP] nick end labeling [TUNEL]) in breast cancer samples obtained at diagnostic core needle biopsy (of cancer) or research core needle biopsy (of unaffected breast) with tissue samples obtained at mastectomy. Measure protein expression of related targets in the following order of priority: progesterone receptor isoforms (progesterone receptor [PR]A and PRB), and estrogen receptor alpha (ERα) and TUNEL using immunohistochemistry (IHC) at baseline and after treatment.

IV. Explore changes in gene expression in breast tissue related to telapristone therapy.

V. Assess change in serum progesterone associated with telapristone therapy. VI. Assess the safety and tolerability of oral and transdermal administration.

OUTLINE: Patients are randomized to 1 of 2 treatment arms.

ARM I (TRANSDERMAL TELAPRISTONE ACETATE): Patients receive telapristone acetate transdermally and placebo orally (PO) once daily (QD) for 4 weeks.

ARM II (ORAL TELAPRISTONE ACETATE): Patients receive placebo transdermally and telapristone acetate PO QD for 4 weeks.

After completion of study treatment, patients are followed up at day 60.

Primary Outcome Measures :
  1. Mean levels of telapristone acetate in breast tissue [ Time Frame: At the time of mastectomy ]
    Will be compared between the two arms to demonstrate that mean levels of telapristone acetate in breast tissue following gel application will result in levels that are not more than 50% lower than those following oral administration.


Secondary Outcome Measures :
  1. Plasma concentrations of telapristone acetate [ Time Frame: At the time of mastectomy ]
    Will be compared between arms to assess whether plasma concentrations of telapristone acetate are significantly lower with transdermal than oral therapy.

  2. Within-breast variation of breast tissue concentration of telapristone acetate [ Time Frame: At the time of mastectomy ]
    Within-breast variation of breast tissue concentration in transdermal and oral groups will be assessed/

  3. Changes in cell proliferation and apoptosis [ Time Frame: From diagnosis to time of mastectomy ]
    Changes in cell proliferation (Ki67 labeling index) and apoptosis (TUNEL) in breast cancer samples obtained at diagnostic core needle biopsy (of cancer) or research core needle biopsy (of unaffected breast) with tissue samples obtained at mastectomy will be assessed. Measure protein expression of related targets in the following order of priority progesterone receptor isoforms (PRA and PRB), ERα, using IHC at baseline and after treatment.

  4. Changes in gene expression [ Time Frame: From diagnosis to the time of mastectomy ]
    Will be measured to identify treatment response. Breast tissue samples will be used for expression arrays and subjected to the confirmatory measurements of messenger ribonucleic acid (mRNA) expression using nanostring for selected genes (tumor necrosis factor receptor superfamily, member 11a, nuclear factor kappa B [NFKB] activator [RANK], tumor necrosis factor [ligand] superfamily, member 11 [RANKL], prolactin receptor, cyclin D1) and for additional genes selected from the array experiments.

  5. Change in serum progesterone [ Time Frame: Baseline to the time of mastectomy ]
  6. Incidence of adverse events, graded according to National Cancer Institute Common Terminology Criteria for Adverse Events version 4.0 [ Time Frame: Up to day 40 ]
    Assessed for oral and transdermal administration.
