Summary

This trial is testing the effectiveness and safety of a drug called amlitelimab for treating severe alopecia areata in adults. Participants will receive injections of the drug and may have the option to

Who is the study for?
Adults with severe alopecia areata (AA) for less than 8 years, no recent hair regrowth, and willing to maintain a consistent hairstyle. They must have lost more than half of their scalp hair. Those with AA for over 8 years can join if they've had some regrowth.
What is being tested?
The trial is testing Amlitelimab injections against a placebo in adults with severe AA. It's double-blind, meaning neither the participants nor the researchers know who gets the real treatment or placebo until after the study.
What are the potential side effects?
Specific side effects aren't listed here, but generally, subcutaneous injections like Amlitelimab could cause reactions at the injection site, potential allergic responses, and other immune-related effects.
