The innovation has been in development for five years by Northwestern University biomedical engineer and professor Patrick Kiser, with lead author Justin Clark. The newly developed, 5.5-cm intravaginal ring (IVR), contains levonorgestrel, a synthetic progestin hormone and tenofovir, an anti-retroviral drug. It is important to find a better way to fight HIV before it’s contracted.
Kiser says: “It was essentially two different Ph.D. theses. One is making the antiretroviral part of the device, and the other is the contraceptive device…. If the trials go well, the IVR could give women around the world, but especially in the developing world, more control.”
