 double-blind trials designed to investigate Breztri as a potential treatment for asthma. 1,2 The trials evaluated the efficacy and safety of Breztri versus maintenance treatment with ICS/LABA in adults and adolescents with uncontrolled asthma. 1,2

Asthma is a common, chronic respiratory disease characterised by inflammation and muscle tightening in the airway (bronchoconstriction), which can make it difficult to breathe. 3 As many as 262 million people worldwide are affected by asthma, 3 and it is estimated that nearly half of those treated with dual therapy remain uncontrolled, which can significantly limit lung function and decrease quality of life. 4,5

Alberto Papi, Professor and Chair of Respiratory Medicine at the University of Ferrara, and Director of the Respiratory Unit, CardioRespiratory Department, S. Anna University Hospital, Ferrara, Italy, and primary investigator, said: "Despite advancements in asthma treatments, millions of patients remain uncontrolled, which can cause frequent breathlessness, coughing and wheezing, significantly impacting their ability to perform daily activities. The results from the KALOS and LOGOS trials are exciting and demonstrate the potential of budesonide/glycopyrronium/formoterol to evolve the standard of care to more effectively treat asthma in a single inhaled triple therapy for patients who remain uncontrolled with dual maintenance therapy."

Sharon Barr, Executive Vice President, BioPharmaceuticals R&D, AstraZeneca, said: "We are excited by the positive results from the KALOS and LOGOS trials, which demonstrate that Breztri could help improve the lives of the millions of patients living with asthma. These asthma data build on the well-established profile of Breztri in COPD, and we look forward to sharing with regulatory authorities to bring this important medicine to a wider group of patients."

There were no new safety or tolerability signals identified for Breztri in KALOS or LOGOS.

Full results from the two Phase III trials will be shared with regulatory authorities and presented at an upcoming medical meeting.

Breztri is an inhaled triple-combination therapy approved for the treatment of chronic obstructive pulmonary disease (COPD) in adults in more than 80 countries worldwide including the US, EU, China and Japan.
