ALS drug trial halted early: what we learned about brain inflammation

NCT ID NCT04066244

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

Summary

This study tested an experimental drug called BLZ945 in 28 people with ALS to see if it could reduce brain inflammation. Researchers used special PET scans to measure inflammation. The study was terminated early, so the full results are not available, but it aimed to gather safety and biological data.

What this could mean

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

Active substance

BLZ945

What this could lead to

If successful, this could point toward a way to reduce brain inflammation in ALS, potentially slowing disease progression.

What could go wrong

This was a small, early-stage study that was terminated, so results are limited. It is unclear if BLZ945 is safe or effective for ALS.
