New antibody trial aims to ease core autism symptoms

NCT ID NCT06500637

First seen Jun 27, 2026 · Last updated Jun 27, 2026

Summary

This Phase 2 study tests whether TB006, an antibody that targets a protein called Galectin-3, can improve core symptoms of autism in adults aged 18 to 35. Forty-five participants will be randomly assigned to receive either TB006 or a placebo for 14 weeks, with an open-label extension for those on placebo. The study measures changes in autism severity using clinician-rated scales and neurodevelopmental assessments.

What this could lead to

If successful, this could point toward a new treatment option for core autism symptoms in adults.

What could go wrong

This is an early Phase 2 trial with only 45 participants, so results may not apply broadly. The drug may not show significant benefit over placebo, and side effects are still being studied.
