Who could benefit from this research
✓Could help
People living with HIV who could benefit from long-acting antibody-based control approaches.
✕Less likely to help
Patients unlikely to respond to antibody-based delivery or with conditions that preclude AAV-based therapies.
What this research studies
Researchers will test delivering protective antibodies via AAV vectors directly into muscle to sustain HIV-1 suppression. The approach builds on prior evidence that bnAbs can block infection and clear infected cells through Fc functions like ADCC and ADCP. The study will address key challenges such as anti-drug antibody responses, antibody escape, and reservoir depletion, with complementary work to understand what antibody features and delivery conditions work best. Findings could inform new, long-lasting HIV-1 control strategies beyond daily antiretroviral therapy.
Why it matters
Potential benefit: If successful, this could lead to durable HIV-1 control without daily medication.
How similar studies have gone: Previous primate studies showed prolonged viral control after AAV-delivered antibodies, supporting potential applicability in humans.
