Severe asthma often requires biologic therapies such as dupilumab and tezepelumab, yet their long-term comparative efficacy remains uncertain due to limited head-to-head evidence. To address this gap, a study used an unanchored matching-adjusted indirect comparison to evaluate the long-term relative efficacy of dupilumab versus tezepelumab in 1,368 patients with severe asthma . The study found that dupilumab significantly reduced the annualized exacerbation rate compared with tezepelumab (mean difference (MD) β0.269), while rates of severe exacerbations requiring hospitalization or ER visits were similar (MD: 0.006).
Dupilumab also showed greater improvement in lung function, with a significant increase in forced expiratory volume (FEV1) in severe asthma (MD: β0.153) and a numerical improvement overall (MD: β0.064). These findings suggest that long-term dupilumab treatment reducesβ¦
