Respiratory Showdown: Dupixent Declares Decisive Victory Over Xolair in Landmark Trial!
- Unprecedented Victory: In a groundbreaking head-to-head trial, Dupixent has emerged as the clear champion over Xolair for patients battling both chronic rhinosinusitis with nasal polyps (CRSwNP) and asthma [1, 2].
- Total Domination: Dupixent didn't just win; it swept all primary and secondary CRSwNP and asthma-related endpoints, offering new hope for profound relief3.
- Treatment Revolution: This first-ever direct comparison of biologic respiratory treatments signals a potential paradigm shift, reshaping how doctors approach these debilitating coexisting conditions [1, 7].
For too long, individuals grappling with the relentless siege of severe chronic rhinosinusitis with nasal polyps (CRSwNP) and the suffocating grip of coexisting asthma have yearned for a definitive champion in their corner. The EVEREST trial, a historic first-ever head-to-head clash between biologic titans, has delivered a resounding answer. Regeneron and Sanofi today unveiled stunning results: Dupixent® (dupilumab) not only met but decisively outperformed Xolair® (omalizumab) on every single measure2.
Imagine living with constantly blocked nasal passages, the loss of smell, and the persistent threat of asthma attacks. The EVEREST trial data, presented at the 2025 European Academy of Allergy and Clinical Immunology (EAACI) Annual Congress, shows Dupixent significantly reduced nasal polyp size, improved sense of smell, and enhanced lung function more effectively than Xolair, with differences observed as early as four weeks [1, 3]. With a generally similar safety profile but fewer serious adverse events for Dupixent, these outcomes provide powerful new insights for patients and physicians navigating complex treatment decisions [2, 5]. This landmark study doesn't just add data; it could rewrite treatment algorithms, heralding a new era where Dupixent, which targets key drivers of type 2 inflammation (IL-4 and IL-13)8, leads the charge in managing these intertwined respiratory diseases, potentially transforming the lives of millions worldwide7.
