HIV prevention breakthrough: shot beats daily pill in large trial

NCT ID NCT02720094

First seen Nov 01, 2025 · Last updated May 16, 2026 · Updated 23 times

Summary

This large study tested whether a long-acting injectable drug (cabotegravir) could prevent HIV infection better than daily oral pills in men and transgender women who have sex with men and are at high risk. Over 4,500 participants received either the injection every 8 weeks or a daily pill. The main goal was to see how many new HIV infections occurred and to check for side effects. Results showed the injection was highly effective and safe for preventing HIV.
