Experimental drug aims to restore platelets in Heparin-Triggered disorder

NCT ID NCT05785819

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

Summary

This study tested an experimental drug called VLX-1005 in people with a rare condition where the blood thinner heparin causes a dangerous drop in platelets (cells that help blood clot). Participants received either VLX-1005 or a placebo alongside standard care. The goal was to see if the drug could help platelet levels recover faster and prevent complications like blood clots or stroke. The study was stopped early, so results are limited.
