The approval is based on data from three pivotal trials (ATLAS, FLAIR, and ATLAS-2M) involving over 1,200 participants:
- Efficacy: In the ATLAS study, 92.5% of participants on long-acting therapy remained virally suppressed at week 48, meeting non-inferiority criteria compared to oral therapy (95.5%).
- Dosing Frequency: The ATLAS-2M study demonstrated that dosing every eight weeks was non-inferior to dosing every four weeks.
- Safety: Injection site reactions were common (83% of recipients) but decreased over time. Serious adverse event rates were 4% in each arm, with no treatment-related deaths.
