The objective of this study is to determine the safety and efficacy effects of two doses of asoprisnil (10 mg and 25 mg) compared with placebo when administered daily for 6 months to premenopausal subjects with symptomatic uterine leiomyomata.

Condition Intervention Phase
Fibroid Uterus Leiomyoma Menorrhagia Metrorrhagia Uterine Fibroids Drug: Asoprisnil Drug: Placebo Phase 3

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Triple (Participant, Investigator, Outcomes Assessor)
Primary Purpose: Treatment
Official Title: A Phase 3,6-Month, Randomized, Double-Blind Study to Evaluate the Safety and Efficacy of Two Doses of Asoprisnil Versus Placebo in Subjects With Uterine Leiomyomata

Further study details as provided by Abbott:

Primary Outcome Measures:
  • Cumulative percent of subjects achieving amenorrhea. [ Time Frame: Month 3 ]

Secondary Outcome Measures:
  • Change from baseline in total symptom severity score and the Uterine Fibroid Symptom-Quality of Life total score. [ Time Frame: Final Visit ]
  • Change from baseline in menorrhagia, metrorrhagia, bloating, pelvic pressure, dysmenorrhea, pelvic pain and urinary symptoms. [ Time Frame: Final Visit ]
  • Change from baseline in the Work Limitation Questionnaire Index. [ Time Frame: Final Visit ]
  • Change from baseline in the two dimensions of the SF-36 (Physical Component Summary and Mental Component Summary). [ Time Frame: Final Visit ]
  • Change from baseline in the monthly bleeding score. [ Time Frame: Final Visit ]
  • Change from baseline in the hemoglobin concentration. [ Time Frame: Final Visit ]
  • Change from baseline in volume of the largest fibroid. [ Time Frame: Final Visit ]
  • Percentage of subjects who discontinue with the intent to have surgery for fibroids during treatment. [ Time Frame: During treatment period ]
  • Percentage of subjects who respond positively to the global efficacy question. [ Time Frame: Final Visit ]

Arms Assigned Interventions
Experimental: 1 Drug: Asoprisnil
Asoprisnil 10 mg Tablet, oral Daily for 6 months
Other Name: J867
Experimental: 2 Drug: Asoprisnil
Asoprisnil 25mg Tablet, oral Daily for 6 months
Other Name: J867
Placebo Comparator: 3 Drug: Placebo
Placebo Tablet, oral Daily for 6 months

Detailed Description:
No medical therapy is currently available for the long-term treatment of abnormal uterine bleeding associated with uterine fibroids. Asoprisnil (10 mg and 25mg) is being evaluated in a Phase 3 program to establish long term safety and effectiveness and therefore provide women with a medical alternative to surgery.
