IPM 027 (The Ring Study)

Status
Completed
Phase
III
Objective

To assess the safety and efficacy of a silicone elastomer vaginal matrix ring.

*The Ring Study reported results early in February 2016 after an independent safety and monitoring board recommended the study proceed to final analysis. It has moved to open-label in South Africa and Uganda. In July, 2016 new analyses announced by MTN at AIDS 2016 found that, among women who appeared to use the monthly ring consistently, HIV risk was cut by at least 56 percent — a statistically significant finding.*
