简要总结
UMPALA is a research study to look at the effect of four different, approved contraceptives on the cervical and vaginal tissues as well as on factors in the blood. Participants will have a baseline examination then receive one of four approved, marketed contraceptive products. Cervico-vaginal assessments will take place 4 weeks after contraceptive initiation and 3 months after to assess changes in mucosal safety after use of various contraceptive products in young, healthy, HIV uninfected women.
详细描述
This clinical study will complete approximately 12 healthy, non-pregnant, HIV-uninfected women aged 18-50 years per contraceptive arm, who are at low risk for sexually transmitted infections (STIs) at two clinical sites, for a total of approximately 96 completed participants. The study will examine changes from baseline, pre-contraceptive dosing to post contraceptive dosing of cervico-vaginal mucosal safety and adverse events.
Participants at each site will be randomized (1:1:1:1) to one of four, marketed, approved contraceptive dosing forms: Levonorgestrel (LNG) 52 mg. Intrauterine System (IUS), Copper Intrauterine Device (IUD), etonogestrel (ETG, Nexplanon, Implanon) contraceptive implant, or DMPA SC contraceptive injection.
Enrollment is expected to take approximately 8 months and each participant is expected to complete the study within 4 months.
