Brief Summary:
The study aims to study the effect of simvastatin on the size of uterine fibroids.

Condition or disease Intervention/treatment Phase
Fibroid Uterus Fibroid Tumor Leiomyoma Fibromyoma Leiomyoma, Uterine Drug: Simvastatin 40mg Drug: Placebo 40 mg Phase 2

Detailed Description:
The study is a phase II double blinded clinical trial to determine feasibility, safety and preliminary clinical efficacy of simvastatin to reduce leiomyoma size. Women with symptomatic fibroids planned to undergo surgical management for fibroids such as hysterectomy or myomectomy will be screened for participation. The eligible women will undergo pre-study evaluation to ascertain study eligibility.The study will enroll 60 participants in total, half will receive simvastatin and the other half will receive a placebo. The study drug and placebo will be an add on to the participants ongoing medical management of fibroids until surgery. The participants will be monitored at intervals for the effect of the drug on fibroid size and symptoms using ultrasound and quality of life questionnaires.

Drug Information available for: Simvastatin

Arm Intervention/treatment
Experimental: Treatment Group
The 30 participants randomized in this group will intake Simvastatin 40mg / day of orally at the same time in the evening, every day for the study duration of 12 weeks prior to undergoing hysterectomy/ myomectomy. The fibroid samples will be collected after the surgery to evaluate the effects of the study medication on the fibroid tissue.
Drug: Simvastatin 40mg
The Treatment Group subjects will orally intake encapsulated Simvastatin 40 mg tablets daily for the 12 weeks duration with water in the evening.
Other Name: Simvastatin

Placebo Comparator: Placebo Group
The 30 participants randomized in this group will intake Placebo 40mg / day orally at the same time in the evening every day for the study duration of 12 weeks prior to undergoing hysterectomy/ myomectomy. The fibroid samples will be collected after the surgery to evaluate the effects of the study medication on the fibroid tissue.
Drug: Placebo 40 mg
The Placebo group will orally intake encapsulated Starch 1500, 40 mg Placebo for 12 weeks duration with water in the evening.
Other Name: Starch 1500 encapsulated




Primary Outcome Measures :
  1. Change in Tumor size volume pre and post study intervention [ Time Frame: Change from baseline to 12 weeks post intervention ]
    Tumor size measured by ultrasound imaging comparing tumor volume using ultrasound imaging. The volume will be reported in Centimeter cubes. The largest radius of the tumor will be used to calculate the volume, this will be measured in centimeters.


Secondary Outcome Measures :
  1. Clinical symptom improvement as determined by the Uterine Fibroid Symptom and Health Related Quality of Life Questionnaire. [ Time Frame: At visit 1 (Screening), At visit 2 (start of the study drug intake), visit 3 (6 weeks after start of the study drug), visit 4( 12 weeks after start of the study drug), and follow up visit at 2 and 6 weeks post hysterectomy ]
    The questionnaire used is the Uterine Fibroid Symptom and Health Related Quality of Life Questionnaire. This questionnaire is an effective and validated tool for detecting differences in symptom severity and health-related quality of life among patients with uterine fibroids. The scale for this questionnaire denotes symptom severity with lowest and highest possible scores of 8 and 40 respectively. Higher scores indicate greater severity of symptoms.

  2. Adherence to the recommended treatment dosing [ Time Frame: At Visit 3 (6 weeks after start of study drug), and Visit 4 (12 weeks after start of the study drug) ]
    Based on review of patient diaries and counting of left over medications bought back by the subject. This will be reported as an overall percentage.

  3. Subject retention [ Time Frame: At visit 2 (start of the study drug intake), visit 3 (6 weeks after start of the study drug), visit 4 (12 weeks after start of the study drug), and follow up visit at 2 and 6 weeks post hysterectomy. ]
    Based on presence at follow up visits to the study site. This will be determined as a simple percentage of subjects that stay in the study until the last visit.


Other Outcome Measures:
  1. Adverse events reporting by organ systems [ Time Frame: At visit 2 (start of the study drug intake), visit 3 (6 weeks after start of the study drug), visit 4 (12 weeks after start of the study drug), and follow up visit at 2 and 6 weeks post hysterectomy. ]
    Based on patient reporting and study team evaluation utilizing CTCAE v.4
