  Purpose

It is well documented that women who have breast cancer may experience a decrease in quality of life and sexual functioning due to side effects from adjuvant endocrine therapy, typically aromatase inhibitors (AIs). Women taking AIs are more likely to report unpleasant urogenital and vaginal symptoms due to the physiologic suppression of estradiol. This treatment can impair sexual functioning and cause a decreased sexual health quality of life.

At the present time, there are no Food and Drug Administration (FDA) approved medications for the vulvovaginal or sexual side effects related to the use of AIs. The lack of treatment options is concerning because the number of women diagnosed with breast cancer continues to increase; their longevity, also, continues to increase with the use of newer adjuvant chemotherapies.

Local health care practitioners have observed that the benefits of vaginal testosterone for sexual health in breast cancer survivors are similar to the benefits of vaginal estrogen in women without breast cancer. As mentioned, vaginal testosterone is not FDA approved for women. Vaginal testosterone is available to women by prescription through compounding pharmacies.

The purpose of this study is to evaluate the impact of using a daily compounded vaginal testosterone cream for 4 weeks (28 days) on breast cancer survivor's reported experience of vulvovaginal symptoms accompanying the use of AIs and their associated quality of life and sexual functioning.

The investigator will enroll postmenopausal women greater than 50 years of age taking AI therapy with reported symptoms of vaginal dryness, pain with intercourse, and changes in sexual functioning since starting AI therapy.

Primary Outcome Measures:
  • Evaluate the effectiveness of a testosterone vaginal cream on the reported symptoms of vaginal dryness, pain with intercourse (dyspareunia), and sexual health quality of life related to aromatase inhibitor therapy in women with breast cancer. [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]

Secondary Outcome Measures:
  • Compare Female Sexual Function Index (FSFI) questionnaire scores [ Time Frame: Baseline and 4 weeks ] [ Designated as safety issue: No ]
    The FSFI questionnaire will be administered to participants prior to starting vaginal testosterone therapy and the survey will be repeated after using the study drug for 4 weeks. The FSFI is a 19-item multidimensional self-administered questionnaire and takes about 15 minutes to complete. The questionnaire uses a 5-point ordinal scale to assess six dimensions of sexual functioning over the past 4 weeks.

  • Sexual Desire [ Time Frame: Baseline and 4 weeks ] [ Designated as safety issue: No ]
    FSFI Questionnaire

  • Sexual Arousal [ Time Frame: Baseline and 4 weeks ] [ Designated as safety issue: No ]
    FSFI Questionnaire

  • Orgasm Functioning [ Time Frame: Baseline and 4 weeks ] [ Designated as safety issue: No ]
    FSFI Questionnaire

  • Dyspareunia (Pain With Intercourse) [ Time Frame: Baseline and 4 weeks ] [ Designated as safety issue: No ]
    FSFI Survey

Study Completion Date: May 2013
Primary Completion Date: April 2013 (Final data collection date for primary outcome measure)
Arms Assigned Interventions
Experimental: Vaginal Testosterone
Testosterone USP micronized powder supplied by Medisca Pharmacy will be compounded by Precision Compounding pharmacy as testosterone 0.3% per 0.5 milliliters (mL) in pharmabase cream. The compounded testosterone vaginal cream will be supplied in pre-filled syringes and each 0.5 mL dose will deliver 300 mcg of testosterone daily. The cream will be applied to the vaginal opening once daily for four weeks (28 days).
Drug: Testosterone
