Monthly HIV prevention pill tested in women – study halted early

Prevention Terminated

This study tested a new monthly pill (islatravir) to see if it could prevent HIV infection better than a daily pill in 730 women at high risk. The trial was stopped early, so results are limited. The goal was to offer a more convenient prevention option.
