New data analyses announced at the AIDS 2016 conference today provide additional evidence suggesting that the monthly dapivirine vaginal ring developed by the nonprofit International Partnership for Microbicides (IPM) provides significant protection against HIV infection in women when used consistently. The new data were released as two open-label studies of the ring begin and as IPM pursues regulatory approvals for the product for its use in developing countries.

What’s on the horizon of HIV prevention? Here are five clinical trials to pay attention to, if you’re interested in what the next big breakthrough in the HIV prevention field may be.

Rectal microbicide gels, applied either daily or before and after sex, are currently being investigated as an option for HIV pre-exposure prophylaxis (PrEP). Given that many people who have anal lready use lube, one hope is for an HIV-prevention product that people could essentially use in place of a lube. But can gels provide enough coverage across rectal tissue if people don’t use an applicator?

The National Institute of Allergy and Infectious Diseases (NIAID), part of the National Institutes of Health (NIH), announced today that it would move forward with an open-label extension study of an HIV prevention tool for women: a silicone ring that continuously releases the experimental antiretroviral drug dapivirine in the vagina. The new study builds on recently announced findings from the ASPIRE trial which found that the dapivirine ring safely provided a modest level of protection against HIV infection in sub-Saharan African women.

This is the first time two phase-three clinical trials have confirmed statistically significant efficacy for a microbicide to prevent HIV. The dapivirine ring was designed to offer potentially long-acting protection against HIV through slow, continuous delivery of dapivirine into the vaginal tissues over the course of four weeks. But there are still several more steps that need to be followed before the ring becomes available to women.

The vaginal ring is one more addition to an already exciting array of antiretroviral-based biomedical options in the prevention toolbox that has ushered in a new era in HIV prevention.

Results from two large-scale studies of a vaginal ring that releases the antiretroviral medicine dapivirine to prevent HIV among women have shown protection of around 30% against HIV. The results are encouraging and show the urgent need to expand investment in research and development for female-controlled methods of HIV prevention. Although less effective than hoped for, the results are the first to show that a sustained release mechanism for antiretroviral medicine is feasible, safe and partially effective in preventing HIV infection among women. Follow-up studies are needed to build on these results and there is a need to better understand how to optimize the HIV prevention effect and support adherence.

Kenneth Mayer: Despite our great progress, we require better tools to fight AIDS. That is why there is so much excitement around this year’s annual Conference on Retroviruses and Opportunistic Infections, which will convene in Boston Feb. 22-25. We are going to learn more about two emerging tools to control the HIV/AIDS epidemic: prevention medicines that are easy to use and protect those who are HIV negative from infection, and advances in vaccine research.
