• The potential for a black box warning on ATI-2138 remains a concern, as it could impact physician and patient acceptance.

5. Notable Q&A Insights:

• The management team discussed the synergistic effects of ITK and JAK3 inhibition, highlighting preclinical data that suggests enhanced anti-inflammatory activity with ATI-2138 compared to selective JAK3 inhibitors.
• Questions regarding dosing strategies revealed that the chosen 10 mg BID dose for the Phase 2 trial was based on preclinical data and comparisons to ritlecitinib.
• The open-label design of the Phase 2 study was justified as a cost-efficient method to quickly gather data, with plans for a larger study if initial results are promising.
• Aclaris emphasized the unmet needs in atopic dermatitis, noting that current treatments do not achieve optimal results for many patients, which presents an opportunity for ATI-2138.
