Zura Bio...outlined its near-term clinical milestones and strategy at Guggenheim Securities’ Emerging Outlook Biotech Summit 2026, emphasizing upcoming Phase 2 readouts for its lead bispecific antibody, tibulizumab, in autoimmune and inflammatory diseases. (MarketBeat) - "New CEO Sandeep Kulkarni says Zura is shifting 'from being an execution company to being a data company,' with two pivotal Phase 2 readouts expected — Q4 this year (hidradenitis suppurativa) and the first half of 2027 (systemic sclerosis)....The HS Phase 2 was expanded to 225 patients with abscess and nodule (AN) count as the primary endpoint and is powered for HiSCR75 assuming a 20–25% placebo-adjusted delta; the trial focuses on biologic‑naïve patients (allows up to 30% TNF inhibitor failures and excludes prior IL‑17 failures) to improve signal detection."

PHASE 1 CLINICAL TRIAL EVALUATING THE PHARMACOKINETICS AND PHARMACODYNAMICS OF A NOVEL IL-17A AND BAFF DUAL ANTAGONIST IN SJOGREN'S SYNDROME (EULAR 2024) - "Overall, this clinical trial demonstrated that tibulizumab was well-tolerated and that the combined neutralization of IL-17A and BAFF disrupts two key pathways involved in disease pathogenesis. These results suggest that tibulizumab may provide significant benefit to those with IL-17A and B cell-mediated autoimmune diseases, including SS, and warrants further exploration in larger clinical trials."

Zura Bio Presents Data for the Tibulizumab (ZB-106) Program at EULAR 2024 (Businesswire) - "The preclinical study was designed to evaluate the respective and combined benefits of inhibiting IL-17A and BAFF in a mouse model of RA. Mice received IL-17A antibodies and/or BAFF antibodies, or a control antibody. Cumulative clinical disease scores were significantly reduced in mice treated with the combination of anti-IL-17A and anti-BAFF compared to the isotype control (p<0.001); combined IL-17A and BAFF inhibition also resulted in less signs of disease compared to individually targeted treatment. Combined IL-17A and BAFF inhibition reduced inflammation significantly compared to the control (p<0.05). Combined IL-17A and BAFF inhibition was associated with a significant reduction of anti-collagen antibodies compared to the control (p<0.01)."
