Dupixent®'s Potential Breakthrough in Bullous Pemphigoid Treatment
Dupixent® (dupilumab) Achieves Priority Review for Bullous Pemphigoid Treatment
If approved, Dupixent would be the first and only targeted medicine to treat BP in the U.S.
Priority Review granted based on positive pivotal results demonstrating significant improvements in sustained disease remission with Dupixent compared to placebo.
Bullous pemphigoid (BP) is a chronic, debilitating, and relapsing skin disease characterized by intense itch, blisters, skin reddening, and painful lesions.
FDA's Acceptance of Dupixent's Application
In a recent announcement, Regeneron Pharmaceuticals, Inc. (NASDAQ: REGN) and Sanofi shared that the U.S. Food and Drug Administration (FDA) has accepted the supplemental Biologics License Application (sBLA) for Dupixent (dupilumab) to treat adults with BP. This is a significant step towards offering a targeted treatment option for this challenging condition.
The sBLA is underpinned by data from a pivotal clinical trial including 106 adults diagnosed with moderate-to-severe BP. In this study, Dupixent demonstrated its effectiveness by achieving sustained disease remission in five times more patients than those receiving a placebo. The criteria for sustained remission involved achieving complete clinical remission while tapering off oral corticosteroids by week 16, continuation on Dupixent for at least 20 weeks, and maintaining no relapse or need for rescue therapy during the treatment period.
Clinical Trial Results
The clinical trial not only met its primary goal but also revealed that Dupixent significantly alleviated disease severity, reduced itchiness, and minimized the necessity for additional corticosteroid treatment.
However, like many medications, Dupixent is associated with certain adverse events. Those reported more frequently than with placebo include peripheral edema, arthralgia, back pain, blurred vision, hypertension, and upper respiratory infections among others. Understanding these potential side effects is crucial for patients and healthcare providers alike.
The Burden of Bullous Pemphigoid
BP predominantly affects older adults and presents a significant burden due to its debilitating symptoms. Approximately 27,000 individuals in the U.S. contend with uncontrolled BP, often not responding adequately to systemic corticosteroids. The disease is marked by intense itching and blister formation, which can lead to complications like skin infections and hinder daily activities.
Recognizing the need for new treatment options, the FDA's Priority Review designation emphasizes Dupixent's potential to significantly improve BP management. This designation is granted for therapies likely to provide substantial enhancements in diagnosis or treatment for severe conditions. Furthermore, Dupixent has previously received Orphan Drug Designation, indicating its intended use for rare diseases affecting fewer than 200,000 individuals in the U.S.
Current Status and Future Prospects
With the FDA's review in progress, the safety and efficacy of Dupixent in treating BP remain under thorough evaluation, and further clinical studies are important to confirm its role in the therapeutic landscape for BP.
