[On a white surface are pills and torn paper with the inscription - ULCERATIVE COLITIS] Despite premarket gains, shares of AnaptysBio (NASDAQ:ANAB [https://seekingalpha.com/symbol/ANAB]) turned lower on Wednesday following disappointing mid-stage trial data for Johnson & Johnson’s (NYSE:JNJ [https://seekingalpha.com/symbol/JNJ]) anti-inflammatory agent JNJ-67484703, designed similar to ANAB’s lead asset rosnilimab. An abstract released ahead of a European medical event on rheumatology indicated on Wednesday that JNJ-67484703, which targets the T cell receptor PD-1, appeared safe and well-tolerated in a Phase 2 trial. While the open-label study involved patients with autoimmune disorders, rheumatoid arthritis, ulcerative colitis, and Sjogren’s disease, the investigators had to discontinue [https://distribution-congress.eular.org/from.storage?image=382xVqPluwnOrBoZFqVPTwuRsEjspEZuD4M0iFMf47K8rMwO0qfRJnlZw-nakUlz0] the trial’s UC arm due to slow recruitment and high withdrawal rate. San Diego, California-based AnaptysBio (NASDAQ:ANAB [https://seekingalpha.com/symbol/ANAB]) announced encouraging long-term data from a Phase 2 trial for its PD-1-targeting anti-inflammatory agent rosnilimab on Tuesday, sending its shares higher in the post-market trading. Concurrently, the company reaffirmed plans to release initial data from a Phase 2 trial for rosnilimab in ulcerative colitis in Q4 2025.
