Intervention Model: Parallel Assignment
Masking: Double (Participant, Investigator)
Primary Purpose: Treatment
Official Title: A Double Blind, Randomized, Controlled, Multicenter, Efficacy and Safety Study of Oral BGS649 vs. Placebo (Each Co-administered With a Combined Oral Contraceptive) Assessing Pain Response in Patients With Refractory Endometriosis

Further study details as provided by Novartis:

Primary Outcome Measures:
  • To demonstrate that from baseline of mean pelvic pain score during month 3 is significantly greater on BGS649 treatment(plus COC)combined oral contraceptive as compared to placebo(plus COC)in patients with refractory endometriosis. [ Time Frame: 12 weeks ]

Secondary Outcome Measures:
  • The change from baseline in mean pelvic pain score [ Time Frame: During 1st & 2nd 4 week periods of trt ]
  • The proportion of patients achieving a response in the pelvic pain score (greater than or equal to 1-point improvement from baseline on the modified B&B scale) [ Time Frame: During the 1st, 2nd & 3rd 4 week periods of trt ]
  • The change from baseline in the pain associated with sexual intercourse (NRS) and the number of days the patient had sexual intercourse [ Time Frame: During the first, second, and third 4-week periods of treatment. ]
  • The percent change from baseline in mean pelvic pain (NRS) score defined as >=2-point improvement in the NRS & >=30% improvement in the NRS [ Time Frame: month 1, 2 & 3 ]

Estimated Enrollment: 68
