ClinicalTrials.gov ID: NCT07181369

What this study is testing

What is GTX-B001?

GTX-B001 is an investigational medicine, given as an infusion into a vein, being studied as a potential treatment for healthy subjects.

Also referred to as ALY-301.

Plain-language explanation of the investigational treatment - it is being studied and is not an approved or proven therapy. The study team can confirm the details.

What it's testing
This is a first-in-human study aimed at determining the safety of a single dose of GTX-B001 in healthy participants and in people with chronic inducible urticaria.
  • Phase 1: an early, usually small safety study
  • Time commitment: about 4 weeks
  • You might receive a placebo (an inactive treatment) instead of the study drug, decided by chance.
