[{"type":"text","content":" HENDERSON, Nev.--(BUSINESS WIRE)--\nZura Bio Limited (Nasdaq: ZURA) (“Zura”), a clinical-stage biotechnology company developing novel and differentiated medicines to meaningfully improve the lives of patients with serious and debilitating autoimmune and inflammatory diseases, today announced that the design of its ongoing Phase 2 TibuSURE clinical trial evaluating tibulizumab (ZB-106) in systemic sclerosis (SSc) has been accepted for poster presentation at the Systemic Sclerosis World Congress, taking place March 5–7, 2026 in Athens, Greece.\n\n\nThe poster, titled “TibuSURE: A Phase 2, Multi-Center, Randomized, Double-Blind, Placebo-Controlled Study with Open-Label Extension to Evaluate the Efficacy, Safety, and Tolerability of Tibulizumab in Adults with Systemic Sclerosis” (Abstract ID 184; Poster P.267), outlines the rationale and design of the global Phase 2 study. No clinical efficacy or safety data will be presented.\n\n\nDiffuse cutaneous systemic sclerosis (“dcSSc”) is a rare, progressive autoimmune disease characterized by immune activation, vasculopathy and fibrosis affecting the skin and internal organs, including the lungs. Treatment options remain limited, highlighting the need for therapeutic approaches that address multiple drivers of disease biology.\n\n\nTibuSURE is the first clinical trial designed to evaluate the dual inhibition of interleukin-17A (“IL-17A”) and B-cell activating factor (“BAFF”) in dcSSc. Tibulizumab is an investigational bispecific antibody engineered to simultaneously neutralize IL-17A and BAFF, two cytokines implicated in inflammation, autoimmunity and fibrotic progression in SSc. By targeting complementary immune pathways, tibulizumab represents a differentiated investigational strategy intended to modulate both inflammatory and fibrotic disease processes.\n\n\nThe ongoing global Phase 2 study is expected to enroll approximately 80 adults who will be randomized 1:1 to receive tibulizumab or placebo every four weeks for 24 weeks, followed by a 28-week open-label extension. The primary endpoint is change from baseline in modified Rodnan Skin Score at Week 24. Topline results are currently anticipated in the first half of 2027.\n\n\nPoster Presentation Details\n\n\n\nPoster Number: P.267\n\n\n\nPresenting Author: Christopher Denton, M.D., Ph.D., FRCP, Professor of Experimental Rheumatology a...
