Clinical Trial Design
This is a multicenter, open-label, randomized, controlled, Phase III study of repeated use of Amphora™ gel compared to Conceptrol® Vaginal Gel as the method of contraception over seven cycles of use. In addition, there is an opportunity for Amphora™ gel subjects to continue with study treatment for up to 13 cycles of treatment upon completion of the first seven cycles of treatment.
A subset of subjects (Amphora™ gel and Conceptrol® Vaginal Gel) will undergo colposcopy at the Admission Visit and at the visits after Cycles 1, 3, and 7 (Treatment Exit). Subjects participating for 13 cycles will also undergo colposcopy after Cycles 10 and 13. Colposcopic photographs will be taken at all visits independent of presence of any suspicious areas. Any suspicious areas and clinical findings will be recorded on the colposcopy case report form. The colposcopy evaluator for the subset will be blinded regarding the treatment group of the subject. If at any time during the study the investigator deems colposcopy necessary, colposcopy will be performed on any subject and will not be limited to subjects in the colposcopy subset.
A subset of subjects (Amphora™ gel and Conceptrol® Vaginal Gel) will also have semi-quantitative cultures for E. coli and clinical yeast performed at the Admission Visit and after Cycles 1, 3, and 7 (Treatment Exit) Visits. Subjects participating for 13 cycles will also undergo the assessments after Cycles 10 and 13. Another subgroup will have quantitative vaginal cultures performed after Cycles 1 and 7 (Treatment Exit) Visits, and also after Cycle 13 for subjects participating in the extension.
Selected research centers will also recruit subjects into the subset of women 36-45 years of age at enrollment.
