Change From Baseline in the Acceptability of Intervention Measure (AIM) Total Score in Staff Study Participants at Month 4
Baseline and Month 4

AIM is a four item survey that assessed the acceptability of an implementation process. The staff study participants were asked to indicate how much they agreed or disagreed with each of the 4 items in the AIM based on their current experiences with implementing the CAB + RPV injection treatment on a five point rating scale (1=completely disagree to 5=completely agree). The AIM total score ranges from 1 to 5 with 1 indicating the least acceptability and 5 the most acceptability. Baseline is defined as the latest pre-treatment assessment with a non-missing value, including those from unscheduled visits. Change from Baseline value is defined as post-dose value minus Baseline value.

Frequently asked questions about CAB LA

What is CAB LA used for?

CAB LA, also known as cabotegravir long-acting, is used for HIV infections. It is being studied as a pre-exposure prophylaxis (PrEP) to prevent HIV acquisition and as a treatment for people with detectable HIV-1 when combined with rilpivirine. The drug is administered intramuscularly and is currently in clinical development.

What does CAB LA target?

CAB LA is a small molecule that targets the HIV integrase enzyme. By inhibiting integrase, it blocks the integration of viral DNA into human host cells, preventing HIV from replicating. This mechanism underlies its use in both HIV prevention and treatment regimens.

Who makes CAB LA?

CAB LA is developed by GSK plc, which trades under the ticker GSK. The company is conducting multiple clinical trials to evaluate the drug's effectiveness in HIV prevention and treatment, including long-acting formulations for extended dosing intervals.

What phase is CAB LA in?

CAB LA is in Phase 3 clinical development for HIV infections. It is an investigational drug and has not been approved by regulatory authorities. The Phase 3 trials are evaluating its use as PrEP and for treatment in people with detectable HIV-1.

What clinical trials is CAB LA in?

CAB LA is being studied in several clinical trials, including NCT06134362, a Phase 3 long-term follow-up for PrEP with 2,996 participants, and NCT06694805, a Phase 3 study in people with detectable HIV-1 with 326 participants. Other trials include NCT06741397 and NCT06786520.

Is CAB LA the same as CAB LA + RPV LA?

CAB LA is the same as CAB LA + RPV LA, which is a combination of cabotegravir long-acting and rilpivirine long-acting. This combination is being studied for HIV treatment, while CAB LA alone is evaluated for HIV prevention as PrEP.
