  48. Slide 48: Question 3

    Question 3 Can you share your thoughts on EQ101’s MOA and the potential use in AA patients? What are you, as a clinician, hoping to observe in this study? 48

  49. Slide 49: How Should We Measure Success?

    HOW SHOULD WE MEASURE SUCCESS? • For a proof of concept study, would like to see early activity and then follow on studies to optimize dosing and administration • Not worried about taking an injectable treatment, but able to grow hair consistently and feel confident • Speed might be less important •

  50. Slide 50: Final Thoughts

    FINAL THOUGHTS • AA has unique properties as a disease—we cannot treat it the same way as psoriasis and atopic dermatitis • Need a safe chronic long term treatment, physicians and patients are looking beyond JAKI • Systemic treatment is in the early innings—please innovate in this space 50 Slides fr
