Breast Cancer Clinical Trial
Vaginal Dehydroepiandrosterone (DHEA) in Postmenopausal Breast Cancer Survivors on Aromatase Inhibitors
Summary
The purpose of this research is to gather information on the safety and effectiveness of Intrarosa®, also known as Dehydroepiandrosterone (DHEA), and prasterone. By doing this study, the investigators hope to learn if Intrarosa® can improve vaginal discomfort. Participants will be assigned to one of two groups. One group will use Intrarosa® once a day. The other group will use Replens™ two times a week.
Full Description
This will be a two-armed, randomized Phase II trial. All study subjects will be asked to fill out a simple 5-question sexual functioning survey. If any concern about sexual functioning is noted, the subject will also be asked to fill out a more extensive Sexual functioning tool, to help determine which domain of sexual functioning is the most bothersome.
Subjects who complete the initial screening will be randomly assigned to the Intrarosa® or Replens™ arm by a 1:1 ratio. Subjects randomized to the Intrarosa® arm will use 6.5 mg daily for 12 weeks (±1 week). Subjects randomized to the Replens™ arm will use a vaginal applicator two times per week for 12 weeks.
At baseline and at 12 weeks, subjects will undergo a physical exam including clinical breast and gynecological exam. During gynecologic exams, the vaginal Potential of Hydrogen (pH) will be determined and a swab of vaginal epithelium sent for determination of the Vaginal Maturation Index (VMI) and Maturation Value (MV). These will be used as objective physiologic markers to determine the improvement in vaginal atrophy. The cytologist's reading specimens will be blinded.
Additionally, all study subjects will be asked to fill out questionnaires at baseline and again in 12 weeks.
Eligibility Criteria
Inclusion Criteria:
Postmenopausal patients with a history of breast cancer who have completed primary treatment with curative intent, who have been on an aromatase inhibitors (AI) for at least 6 months
Stage I-III, hormone receptor positive breast cancer regardless of human epidermal growth factor receptor 2 (HER2) status
Postmenopause defined as 12 months of spontaneous amenorrhea, or 6 months of spontaneous amenorrhea with serum follicle-stimulating hormone (FSH) levels > 40 mIU/mL (milli-international units per milliliter), or 6 weeks postsurgical bilateral oophorectomy with or without hysterectomy. FSH level will be documented on all subjects.
Patients reporting any symptoms of vaginal dryness or dyspareunia as assessed by the Brief Sexual Symptom Checklist for Women (BSSC-W) or the Female Sexual Function Index (FSFI)
No evidence of active malignant breast or gynecologic disease
Absence of undiagnosed, persistent or recurring genital bleeding that has not been evaluated to determine the cause [6]
No planned changes in AI during the study period
Mammogram (if appropriate, as determined by the treating physician and will be documented) within 12 months of study entry
Patients with documented normal Pap within 12 months of study entry
Exclusion Criteria:
Use of any estrogen or progesterone depot-preparation drug or progestin implant in the last 6 months before study entry
Use of any androgen or anabolic steroids in the last 6 months before study entry
Use of any oral or transdermal hormonal products (estrogen, progestin, or DHEA) within the last 8 weeks prior to study entry; however, a subject can elect to wait for an 8-week washout period before study entry.
Use of any vaginal or intrauterine hormonal products in the last 8 weeks; however, a subject can elect to wait for an 8-week washout before study entry.
Use of any natural over the counter estrogenic products in the last 6 months; however, a subject can elect to wait for a 6-month washout before study entry.
Concomitant vulvar and vaginal surgical or laser treatments
Vaginal infection or confounding vulvar or active vaginal disease process
Prior radiation to the pelvis or history of gynecologic cancer
Inability to tolerate a vaginal/speculum exam
Undiagnosed, persistent or recurring genital bleeding or other indication of active pelvic disease process that has not been evaluated [6]
Clinically significant uncontrolled depression or severe psychiatric symptoms
If subject has an established routine of inert vaginal lubricant use for routine or occasional relief of vulvar or vaginal symptoms prior to the study period, it may be continued during the study period along with the study drug.
