Three long-acting HIV antibodies with planned ART breaks for children treated early in Botswana

A Clinical Trial of Three Broadly Neutralizing Antibodies and Analytic Treatment Interruption in Early-Treated Children in Botswana

NIH-funded research Harvard University D/b/a Harvard School of Public Health · NIH-11126770

This project gives three long-lasting HIV antibodies to children who started treatment early and pauses their regular HIV pills to test whether the antibodies can keep the virus under control.

What this research studies

If your child joins, they would receive infusions of three broadly neutralizing antibodies (bNAbs) on a scheduled rotation. While on the antibodies, doctors will pause the child’s daily antiretroviral therapy (an analytic treatment interruption) and closely monitor viral levels, safety, and immune signs. The study builds on an earlier Tatelo trial where two bNAbs kept virus suppressed without ART for many children, and it aims to improve on that by using three antibodies and a stepwise design. Visits and testing will take place at study clinics in Botswana with frequent monitoring to restart ART if needed.

Who could benefit from this research

Good fit: Children who started ART very early after infection, are currently receiving care and viral suppression, and are able to attend frequent clinic visits in Botswana would be the ideal candidates.

Not a fit: People who were not treated early, who are not currently virologically suppressed, who cannot safely stop ART, or who live outside the study region are unlikely to benefit from joining this trial.

Why it matters

Potential benefit: If successful, this approach could reduce time on daily ART, lower drug-related side effects during growth, and increase the chance of long-term virus control without continuous pills.

How similar studies have performed: A prior proof-of-concept Tatelo trial showed monthly dual bNAbs kept virus suppressed without ART for 24 weeks in 44% of early-treated children, while the three-antibody rotation here is a newer strategy.
