The potential for JAK inhibitors to treat alopecia areata may be underappreciated by investors because the Street does not appear to be ascribing enough value to the opportunity, Cantor Fitzgerald analyst Louise Chen tells investors in a research note. Of the three companies she covers developing JAKs for hair loss, Aclaris Therapeutics (ACRS), Eli Lilly (LLY) and Pfizer (PFE), the analyst believes Aclaris offers the best risk/reward and greatest upside potential. The company has a market cap below $700M and two potential "shots on goal" for alopecia areata, Chen writes. She estimates combined peak sales of $1B-plus for both opportunities and keeps an Overweight rating on Aclaris. The physicians the analyst spoke to believe the company's JAKs for hair loss will work.
