- Conditions
- HIV Infections
- Interventions
- Registration Number
- NCT05996471
- Lead Sponsor
- ViiV Healthcare
- Brief Summary
The study aims at evaluating the efficacy of VH3810109, dosed in accordance with the dosing schedule as either intravenous (IV) infusion or subcutaneous (SC) infusion with recombinant hyaluronidase (rHuPH20), in combination with cabotegravir (CAB) intramuscular (IM) dosed in accordance with the dosing schedule in virologically suppressed, Antiretroviral therapy (ART)-experienced adult participants living with HIV. VH3810109 plus rHuPH20 plus Cabotegravir arm of the study has been discontinued based on preliminary results. The study will be conducted in 3 parts followed by a Long-Term Follow-up phase (LTFU).

Prior/Concurrent Clinical Study Experience • Participant enrolled in a prior or concurrent clinical study that includes a drug intervention within the last 30 days.
Diagnostic Assessments • Any acute laboratory abnormality at Screening, which, in the opinion of the investigator, would preclude the participants inclusion in the study of an investigational compound.
• Any evidence of viral resistance based on the presence of any major cabotegravir resistance-associated mutation [IAS-USA, 2022] in any historic resistance test result.

Other Exclusion Criteria
• To assess any potential impact on participant eligibility with regard to safety, the investigator must refer to the IB and supplements, approved product labels, and/or local prescribing information for detailed information regarding warnings, precautions, contraindications, AEs, drug interactions, and other significant data pertaining to the study drugs.
