The research viewed 135 COPD patients along with constant bronchitis obtain either 600 milligrams of tozorakimab or even placebo every 4 weeks for 12 full weeks.The trial overlooked the major endpoint of showing an improvement in pre-bronchodilator forced expiratory volume (FEV), the amount of air that a person can exhale in the course of a forced sigh, according to the theoretical.
