Baseline severity and treatment response
“Does treatment response vary with baseline disease status?” Dr. Chovatiya asked. “Yes. People with very severe hair loss [defined as a SALT score of 95 or higher] tended to do worse, while the rest of the study population did even better – an almost twofold difference. This means that you want to treat as early as you possibly can. It’s interesting to note that you don’t see this difference as much in the case of eyebrows and eyelashes. This makes sense, though. Eyebrows and eyelashes probably behave differently in terms of growth than the scalp does.”
Certain baseline characteristics of patients in BRAVE-AA1 and BRAVE-AA2 portended better outcomes. Women tended to fare better than men, but individuals who had longer histories of AA did not respond well. “People who had a shorter duration of their current episode of AA also did better than people who had a longer current episode, so we want to think about treating as soon as we possibly can,” Dr. Chovatiya said.
Dr. Chovatiya disclosed that he is a consultant to, a speaker for, investigator, and/or a member of the advisory board for several pharmaceutical companies, including Eli Lilly.
