QUARTZ: Comparative Effectiveness of Switching From Albuterol to Albuterol/Budesonide Versus Adding Low-Dose Inhaled Corticosteroids or Leukotriene Receptor Antagonists to Albuterol Among Adults With Asthma in the United States
Brief summary
Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.
The QUARTZ study is a retrospective observational cohort study using a prevalent new-user design and U.S. healthcare claims data to evaluate treatment effectiveness among patients with asthma. The study compares the real-world effectiveness of switching from albuterol-only rescue therapy to albuterol/budesonide versus adding low-dose inhaled corticosteroids (ICS) or leukotriene receptor antagonists (LTRA) while continuing albuterol. The primary objective is to assess the comparative effectiveness of these treatment strategies in reducing severe asthma exacerbations in routine clinical practice in the United States.
