Abstract Background TEV-48574 is a human antibody that targets tumor necrosis factor (TNF)-like ligand 1A, also known as TNF superfamily member 15 (TNFSF15). It is in clinical development as a potential treatment for ulcerative colitis (UC) and Crohn’s disease (CD). TL1A signalling is believed to amplify immune-mediated inflammation in asthma and inflammatory bowel disease (IBD); thus, targeting TL1A may mitigate over-activation of immune responses. A proof-of-concept phase 2A study evaluated safety, tolerability and efficacy of TEV-48574 as treatment for adults with severe uncontrolled asthma (Clinicaltrials.gov NCT04545385). Although the study terminated (after meeting pre-specified criteria for futility at a preplanned interim analysis) the drug demonstrated favourable safety, tolerability and immunogenicity data, supporting the potential use of anti-TL1A treatment in patients with UC and CD. Methods TEV-48574 was administered as a loading dose followed by 7 maintenance doses given subcutaneously (sc) every 2 weeks for 16 weeks in adult patients (n = 65) with severe T2-low asthma with no/low inflammation at baseline. The primary efficacy endpoint was reduction in patients who experience loss of asthma control (LoAC). Patients were monitored for LoAC at bi-weekly visits and daily by use of a handheld spirometer/e-diary. Safety was assessed throughout the study. Results Of 65 randomized patients, 64 received at least one dose of study drug and were included in the safety ana...
