HIV gene therapy passes first safety check in tiny study

NCT ID NCT02390297

First seen Jun 25, 2026 · Last updated Jun 27, 2026 · Updated 1 time

Summary

This study follows 11 people who previously received a gene therapy called Cal-1 for HIV. The goal is to watch for any delayed side effects over many years. Researchers will also check whether the modified cells are still present and active in the blood. It is a safety-only study, not designed to measure how well the therapy controls HIV.

What this could mean

Our plain-language read of the trial. This is informational only — not medical advice or a prediction.

Active substance

Cal-1 (gene-modified CD4+ T cells and/or CD34+ stem cells)

What this could lead to

If successful, this could confirm that Cal-1 gene therapy is safe over many years, supporting its use as a long-term HIV control strategy.

What could go wrong

This is a very small follow-up study (11 people) focused only on safety, not on whether the treatment works. It cannot prove effectiveness, and rare side effects may still emerge later.
