Обзор

This study is being conducted to determine the safety of repeat metered cryospray (MCS) treatment in patients with COPD with chronic bronchitis previously treated with MCS.

Подробное описание

This study is being conducted to determine the safety of repeat metered cryospray (MCS) treatment in patients with COPD with chronic bronchitis previously treated with MCS.

This is an open-label study. Eligible subjects will have previously completed the SPRAYCB study (NCT03893370). Subjects will receive 2 sessions of bronchial metered cryospray using RejuvenAir® System. Each session will be separated by approximately 30-45 days. Subjects will be followed at 3-month and at 6-months post second procedure.
