Summary

This study evaluates the real-world effectiveness and safety of a long-acting injectable HIV treatment consisting of cabotegravir and rilpivirine in people living with HIV-1. The focus is on individuals with HIV-1 subtype A6, which is common in Eastern Europe and among people who acquired HIV in that region, and on comparison with individuals with subtype B and those with an unknown subtype.

Although long-acting cabotegravir and rilpivirine are widely used and effective, limited real-world data are available on how well this treatment works in people with HIV-1 subtype A6. This is important because subtype A6 has been suggested as a potential risk factor for treatment failure, but current evidence is inconclusive.

The study uses existing medical records from treatment centers in Poland, Germany, and the Czech Republic. It includes adults with HIV who have received at least one injection of long-acting cabotegravir and rilpivirine and follows their clinical outcomes for up to 24 months. Researchers will assess viral suppression, treatment persistence, adherence to injection schedules, and reasons for treatment discontinuation.

The results of this study will help clinicians better understand whether HIV-1 subtype A6 affects treatment outcomes and whether knowing a patient's HIV subtype is important when deciding to switch to long-acting injectable therapy. The findings may support safer and more effective use of this treatment in diverse patient populations.

Conditions

  • Human Immunodeficiency Virus (HIV)-1 Infection
  • HIV-1 Subtype A6 Infection
  • HIV-1 Subtype B Infection
  • Virologically Suppressed HIV-1 Infection Receiving Long-Acting Antiretroviral Therapy

Interventions

DRUG

Cabotegravir Plus Rilpivirine Long-Acting Injectable

Cabotegravir plus rilpivirine long-acting (CAB/RPV LA) is a complete antiretroviral regimen administered as intramuscular injections and approved for the maintenance treatment of HIV-1 infection in adults. In this observational, retrospective study, CAB/RPV LA is used as part of routine clinical care and is not assigned by the study protocol. Participants received CAB/RPV LA according to local prescribing information, including dosing intervals and injection windows. The study evaluates real-world clinical outcomes of CAB/RPV LA across different HIV-1 subtype groups (subtype A6, subtype B, and unknown subtype). Outcomes of interest include virologic effectiveness, treatment persistence, adherence to injection schedules, and treatment discontinuation. No study-specific modifications to dosing, administration, or clinical management are performed.
