AstraZeneca PT027 recommended by FDA advisory committee as new rescue treatment for asthma

Bradley E. Chipps, Past President of the American College of Allergy, Asthma & Immunology and Medical Director of the Capital Allergy & Respiratory Disease Center in Sacramento, US, said: "Millions of people with asthma rely on their albuterol rescue inhaler to alleviate acute symptoms, but this does not treat the underlying inflammation, leaving patients at risk of severe asthma exacerbations, regardless of their disease severity or level of control. If approved, PT027 could transform the current rescue treatment approach."

Mene Pangalos, Executive Vice President, BioPharmaceuticals R&D, AstraZeneca, said: "We are pleased that the Pulmonary-Allergy Drugs Advisory Committee has recognised the potential for PT027 to deliver important benefits for people with asthma, as a first-in-class treatment option in the US. We look forward to working with our partner Avillion and the FDA to progress the application and discuss the next steps, including for adolescents and children."

Asthma is a chronic, inflammatory, variable respiratory disease that affects as many as 339 million people worldwide, including over 25 million in the US. Globally, more than 176 million asthma attacks are experienced each year.

The NDA submission was based on results from the MANDALA, DENALI, and TYREE Phase III trials. In MANDALA, PT027 significantly reduced the risk of severe exacerbations compared to albuterol in patients with moderate to severe asthma when used as an as-needed rescue medication in response to symptoms. In DENALI, PT027 significantly improved lung function compared to the individual components, albuterol, and budesonide, in patients with mild to moderate asthma.6

The safety and tolerability of PT027 in these trials were consistent with the known profiles of the components.

Results from the MANDALA trial were published in the New England Journal of Medicine in May 2022.

PADAC reviews and evaluates available data concerning the safety and effectiveness of marketed and investigational human drug products for use in the treatment of pulmonary disease and diseases with allergic and/or immunologic mechanisms and makes appropriate recommendations to the Commissioner of Food and Drugs.
