Conclusions • Oral KORSUVA TM did not meet Primary Endpoint of I - NRS change from baseline at week 12 in ITT population • However, statistically significant improvement was observed in mild - to - moderate subjects throughout Week 12 • Oral KORSUVA TM resulted in statistically significant improvement in the registration endpoint 4 - point responder analysis in subjects with mild to moderate AD at Week 12 • Oral KORSUVA TM was generally well tolerated across all doses Efficacy and safety data support further development of KORSUVA in mild - to - moderate AD patients – EOP2 FDA meeting target for 2H, 2021 The FDA has conditionally accepted KORSUVA Œ as the trade name for difelikefalin injection. Difelikefalin injection is an investigational drug product and its safety and efficacy have not been fully evaluated by any regulatory authority.
