Johnson & Johnson reported that 58% of patients receiving icotrokinra 200 mg achieved ACR20 at Week 16 in ICONIC-PsA 1, versus 41% with placebo. The oral IL-23 receptor peptide also showed skin responses. The company reported no new safety signals through Week 24; active psoriatic arthritis remains an investigational indication.
