The ERASE II study is a prospective follow-up study designed to assess the long-term impact of successful eradication of Pseudomonas aeruginosa (PA) in patients with bronchiectasis. Building on the findings of the initial ERASE study, which evaluated the efficacy and safety of Tobramycin Inhalation Solution, ERASE II aims to determine whether successful PA eradication influences patient prognosis over an extended period. The study will involve a total observation period of 36 months, consisting of the initial 9 months of the ERASE study followed by an additional 27 months of comprehensive follow-up. Key outcomes to be assessed include patients' quality of life, lung function, frequency of pulmonary exacerbations, frequency of hospitalization, and overall treatment costs. Additionally, the study will examine the timing and incidence of any potential reinfections with Pseudomonas aeruginosa.
