Objectives Primary - Determine the efficacy of low-dose testosterone, in terms of average intra-patient change in libido, in postmenopausal female cancer survivors with a decreased libido.
Secondary - Determine the toxic effects of this drug in these patients.
- Determine the levels of estrogen and testosterone and SGOT in patients reporting a decreased libido before and after treatment with this drug.
- Determine whether increasing libido significantly positively affects pleasure from sexual activity in patients treated with this drug.
- Determine the effect of this drug on vitality, general quality of life, and overall mood in these patients.
Entry Criteria Disease Characteristics:
- History of cancer
- Currently has a sexual partner
- Reports a decrease in sexual desire or libido and would like an intervention for it
- Defined as a score of less than 8 on the numerical analogue scale
- Hormone receptor status:
Prior/Concurrent Therapy:
Biologic therapy Chemotherapy - Concurrent cytotoxic chemotherapy (e.g., tamoxifen or aromatase inhibitors) allowed
Endocrine therapy - No prior testosterone
- No prior androgen agents for libido
- Concurrent selective estrogen receptor modulators allowed
- Concurrent vaginal estrogen allowed provided it was initiated ≥ 1 month ago and continued at the same dose during study participation
Radiotherapy - Concurrent radiotherapy allowed
Surgery - No prior major pelvic surgery resulting in anatomical changes to the vaginal anatomy
- Prior hysterectomy allowed
Other - Concurrent antidepressants for postmenopausal mood or hot flashes allowed provided patient is on a stable dose that will not change within the next 8 weeks
- No concurrent anticoagulants or propanolol
- Concurrent anticoagulants for central or peripheral line maintenance (e.g., warfarin 1 mg daily or heparin flushes) allowed
- No other concurrent treatment for decreased libido
Patient Characteristics:
Age Sex Menopausal status - Postmenopausal, defined as the following:
- Surgically induced menopause OR absence of a period for at least 12 months (naturally or treatment-induced)
Performance status Life expectancy Hematopoietic - WBC ≥ 2,500/mm3
- Platelet count ≥ 100,000/mm3
- Hemoglobin ≥ 10 g/dL
- No untreated anemia
Hepatic - SGOT ≤ 1.5 times upper limit of normal (ULN)
- No known liver disease
Renal - Creatinine ≤ 1.5 times ULN
- No renal dysfunction
Cardiovascular - No coronary artery disease
- No congestive heart failure
Other - No untreated hypothyroidism
- No diabetes
- No major depressive disorder requiring treatment
Expected Enrollment A total of 140 patients (70 per treatment arm) will be accrued for this study within 14 months. Outline This is a double-blind, placebo-controlled, randomized, crossover, multicenter study. Patients are stratified according to antidepressant medication use (yes vs no), age (under 50 vs 50 to 60 vs 61 to 70 vs over 70), tamoxifen or other selective estrogen receptor modulator use (yes vs no), and ovarian status (in place [natural menopause or hysterectomy] vs not in place [bilateral oophorectomy]). Patients are randomized to 1 of 2 treatment arms. - Arm I: Patients receive topical testosterone once daily for 4 weeks.
- Arm II: Patients receive a topical placebo once daily for 4 weeks.
After 4 weeks, patients cross over to the other treatment arm. Changes in sexual functioning, mood states, and medical outcome vitality are assessed at baseline and then at the end of weeks 4 and 8. Patients who continue or restart testosterone cream after the 8-week study period are followed at 6 months.

Note: The purpose of most clinical trials listed in this database is to test new cancer treatments, or new methods of diagnosing, screening, or preventing cancer. Because all potentially harmful side effects are not known before a trial is conducted, dose and schedule modifications may be required for participants if they develop side effects from the treatment or test. The therapy or test described in this clinical trial is intended for use by clinical oncologists in carefully structured settings, and may not prove to be more effective than standard treatment. A responsible investigator associated with this clinical trial should be consulted before using this protocol. Back to Top |
