Impact on Asthma Exacerbations
Exdensur has demonstrated notable efficacy in reducing asthma exacerbations. In clinical trials, patients experienced a significant decrease in annualized asthma attacks, with a reduction rate of:
| Study | Reduction in Exacerbations |
|---|---|
| SWIFT-1 | 58% |
| SWIFT-2 | 48% |
Moreover, a pooled analysis revealed a 72% decrease in clinically significant exacerbations requiring hospitalization or emergency department visits compared to placebo.
Broader Context of Severe Asthma Treatment
Severe asthma affects approximately 2 million Americans, with half experiencing frequent exacerbations, often leading to hospital care. While biologics have shown promise, only 20% of eligible patients currently receive them. The introduction of Exdensur could mitigate these challenges by providing a more manageable treatment option.
