Neal Walker announced that Aclaris is moving ATI-2138 forward in a proof-of-concept study for moderate to severe atopic dermatitis. Joe Monahan discussed ATI-2138 as a covalent inhibitor targeting ITK and JAK3, highlighting its unique pharmacology, preclinical activity in various disease models, and positive Phase 1 study results supporting advancement to Phase 2. Aclaris is expanding efforts in the ITK pathway with discovery of next-generation ITK inhibitors. Kevin Balthaser mentioned the company has a strong balance sheet with $161 million in cash, cash equivalents, and marketable securities at the end of Q1 2024, and cost containment initiatives are on track.

The first indication for ATI-2138 is a proof-of-concept Phase 2 study in moderate to severe atopic dermatitis, an open-label 12-week, 15-patient study to assess safety, PK, and early efficacy. Neal Walker mentioned the Phase 2a study for atopic dermatitis is underway, with top-line data expected within a year of the call.

Forward-looking statements involve risks, changes in circumstances, assumptions, and uncertainties, as described in the company's Form 10-K and other SEC filings.
