MANDALA phase III trial of PT027 a new FDC of albuterol and budesonide
MANDALA phase III trial of PT027, a new FDC of albuterol & budesonide, used as an as-needed rescue medicine, significantly reduced risk of severe exacerbation compared to albuterol by 27% in patients with asthma Full results from the positive MANDALA phase III trial showed that PT027 (albuterol/budesonide) at two different strengths of budesonide, an inhaled corticosteroid (ICS), used as an as-needed rescue medicine, demonstrated a statistically significant reduction in the risk of a severe exacerbation versus albuterol rescue in patients with moderate to severe asthma.
PT027 is a potential first-in-class inhaled, fixed-dose combination rescue medication containing albuterol, a short-acting beta2-agonist (SABA), and budesonide in the US. It is being developed by AstraZeneca and Avillion.
Globally, more than 176 million asthma attacks are experienced each year.
Compared with albuterol rescue, PT027 at the 180mcg albuterol/160mcg budesonide dose reduced the risk of a severe exacerbation by 27% (p<0.001) in adults and adolescents. In the trial, patients were randomised to receive PT027 or albuterol rescue, on top of their usually prescribed maintenance ICS, with or without additional controller medicines.
In secondary endpoints, PT027 (180mcg albuterol/160mcg budesonide) demonstrated a 33% reduction in mean annualised total systemic corticosteroid exposure (p=0.002) and a 24% reduction in annualised severe exacerbation rate (p=0.008). A numerically higher odds of patients experiencing an improvement in symptom control and quality of life was also observed after 24 weeks of treatment with PT027 compared to albuterol rescue.
Adverse events (AEs) were similar across the treatment groups in the trial and consistent with the known safety profiles of the individual components, with the most common AEs including nasopharyngitis and headache.1
