FDA Approves First Twice‑Yearly HIV Prevention Injection: A New Era in PrEP

Recently, the U.S. Food and Drug Administration granted approval for lenacapavir, marketed under Yeztugo, marking a historic milestone as the **first-ever HIV prevention shot administered only twice a year.

Proven Near‑Total Protection

Clinical trials—PURPOSE 1 and PURPOSE 2—demonstrated staggering results: 99.9% of participants remained HIV‑negative. In PURPOSE 1 (predominantly cisgender women), efficacy was effectively 100%, while PURPOSE 2 reflected similar success rates among men who have sex with men and other high‑risk groups .

How It Works

Lenacapavir is a long‑acting capsid inhibitor. A small depot is injected under the skin every six months, steadily releasing the drug to stop HIV from replicating .

Advantages Over Existing PrEP

  • Simplified schedule: Just two injections annually versus daily pills or bi-monthly shots like Apretude.

  • Better adherence: Ideal for those with difficulty maintaining daily regimens or facing stigma.

  • High efficacy: With 99.9% success, this long-acting option could reshape global HIV prevention strategies.

Cost & Access

The U.S. list price is approximately $28,218 per year ($14,109 per dose). Gilead has pledged support via insurance assistance and no-profit supply deals targeting low-income countries, offering generic licenses to help broaden affordability.

Why It Matters

This approval introduces a powerful alternative for HIV prevention. Experts believe that biannual dosing could significantly enhance uptake and retention among vulnerable communities—bringing us closer to controlling the HIV epidemic.

This groundbreaking development—yeztugo’s twice-yearly PrEP injection—offers near-perfect protection with just two shots a year. Yet, equitable distribution remains vital to realize its full global impact.
