ClinConnect Summary
The SIGNAL-AA trial is studying a new treatment called bempikibart (ADX-914) for people with severe alopecia areata, a condition that causes significant hair loss. This trial is split into two parts. In Part A, participants were randomly assigned to receive either the treatment or a placebo (which looks like the treatment but has no active ingredients) to see how effective it is. Part B will continue to evaluate bempikibart to determine how well it works, how safe it is, and how well patients tolerate it.
To join the trial, participants need to be adults aged 18 to 75 who have been diagnosed with severe alopecia areata, meaning they have lost at least 50% of their hair on their scalp. However, people with other forms of hair loss, those who have had hair transplants, or those currently taking other hair loss treatments are not eligible. Participants in the trial can expect to be closely monitored and may experience some side effects, but the goal is to find a safe and effective treatment for this challenging condition.
