What this phase means
Phase 3: this treatment already looked useful in smaller studies. Now it is tested in a large group, often against standard care or a dummy treatment, to see if it should be approved.
Phase labels are FDA/ICH categories applied to the registry Phase field. They are not a finding that this study succeeded.
What the registry says happens
If you join, the listed intervention(s) are Lenacapavir, Lenacapavir Tablet, or Teropavimab. The registry lists allocation as randomized. The goal of this clinical study is to compare how effective a long-acting treatment of injectable combination of lenacapavir (LEN), teropavimab (TAB), and zinlirvimab (ZAB) is versus continuing a daily oral HIV treatment in adults with HIV-1 whose virus is already well controlled, after 1 year (52 weeks) of treatment.
They plan to enroll about 590 people at 2 sites. Taking part typically means taking a study drug (or dummy pill) plus check-ins.

Interventions: Lenacapavir, Lenacapavir Tablet, Teropavimab, Zinlirvimab, SBR
