A Study to Investigate Cabotegravir Ultra Long-Acting (CAB ULA) Plus Rilpivirine Ultra Long-Acting (RPV ULA) in Adults and Adolescents With HIV Who Are Virologically Suppressed

This study compares the efficacy, safety and tolerability of CAB ULA and RPV ULA administered with CAB long acting (LA) and RPV LA administered in adults and adolescents with HIV who are virologically suppressed on anti-retroviral therapy (ART).

Key information

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

Patient Study Participant (PSP) Inclusion criteria:

  • Adults and adolescents with HIV-1 infection aged 12 years or older with a weight >35 kg.
  • Documented HIV-1 RNA measurements <50 copies/mL in the 12 months prior to Screening.
  • HIV-1 RNA <50 copies/mL at screening assessment.
  • Must be on current daily oral antiretroviral regimen for at least 6 months uninterrupted prior to Screening.
  • Any prior switch in therapy must have occurred due to tolerability/safety, access to medications, or convenience/simplification, and must NOT have been done for virologic treatment failure (HIV-1 RNA ≥200 copies/mL).

Exclusion criteria

Patient Study Participant (PSP) Exclusion criteria:

  • Any evidence of primary resistance based on the presence of any major known INSTI (including CAB) or NNRTI (including RPV) resistance-associated mutation.
  • Treatment with an HIV-1 immunotherapeutic vaccine within 90 days of screening.
  • Any history of receiving long-acting therapy for HIV.
  • Previous exposure to CAB and/or RPV for treatment or prevention of HIV-1 infection.
  • Significant uncontrolled or clinically relevant comorbidities (e.g., cardiovascular, hepatic, renal, neurological, psychiatric) that may impact safety or study participation.

Note: Other protocol defined Inclusion/Exclusion criteria may apply.

Primary outcomes

  1. Percentage of participants with plasma HIV-RNA greater than or equal to (>=) 50 copies (c)/mL as per Food and Drug Administration (FDA) Snapshot algorithm

    Time frame: At Month 11

Secondary outcomes

  1. Percentage of participants with plasma HIV-RNA >= 50 c/mL as per FDA Snapshot algorithm

    Time frame: At Month 23

  2. Percentage of participants with plasma HIV-RNA less than (<) 50 c/mL as per FDA Snapshot algorithm

    Time frame: At Month 11 and Month 23

  3. Percentage of participants with confirmed virologic failure (CVF)

    Time frame: Up to Month 23

    CVF is defined as 2 consecutive HIV-1 RNA levels >=200 c/mL.

  4. Number of participants with drug-related adverse events (AEs) as per severity of Grade 2-5

    Time frame: Up to Month 23

    An AE is any untoward medical occurrence in a clinical study participant, temporally associated with the use of a study intervention, whether or not considered related to the study intervention. Severity is graded according to the Division of Acquired Immunodeficiency Syndrome (DAIDS) grading criteria, where Grade 2 = moderate, Grade 3 = severe, Grade 4 = potentially life-threatening, Grade 5 = death.

  5. Number of participants with drug-related serious adverse events (SAEs)

    Time frame: Up to Month 23

    An SAE is defined as any untoward medical occurrence that results in death, is life threatening, requires hospitalization or prolongs existing hospitalization, results in disability/incapacity or other medically significant events.

  6. Number of participants who discontinue treatment due to AEs or injection intolerability

    Time frame: Up to Month 23

  7. Number of participants with treatment emergent genotypic or phenotypic resistance to CAB and RPV

    Time frame: Up to Month 23

  8. Ctrough of CAB and RPV

    Time frame: Up to Month 23

  9. Maximum concentrations post dose (Cmax) of CAB and RPV

    Time frame: Up to Month 23

  10. Area under the curve (AUC) of CAB and RPV

    Time frame: Up to Month 23

  11. Absolute value of CD4+ cell counts in participants

    Time frame: Up to Month 23

  12. Change from Baseline in CD4+ cell counts in participants

    Time frame: At Month 23 compared to baseline (Day 1)
