Tudorza® Meets Primary Endpoints in ASCENT Study
Circassia Announces Tudorza® Successfully Met Both Primary Endpoints in ASCENT Phase IV Study in Chronic Obstructive Pulmonary Disease
Ø Significantly reduced COPD exacerbations
Ø Demonstrated favourable cardiovascular safety profile similar to placebo
Ø Circassia's partner AstraZeneca plans to file data for inclusion in US label
Oxford, UK - 4 December 2017: Circassia Pharmaceuticals plc ("Circassia" or "the Company"; LSE: CIR), a specialty pharmaceutical company focused on respiratory disease, today announces positive top-line results from the ASCENT phase IV post-marketing study of Tudorza®* in over 3,600 patients with moderate to very severe chronic obstructive pulmonary disease (COPD) and documented cardiovascular risk factors. The study was conducted by the Company's partner AstraZeneca. Tudorza® contains the long-acting muscarinic antagonist (LAMA) aclidinium bromide administered via Pressair®** inhaler.
The ASCENT study met its primary efficacy endpoint, with Tudorza® demonstrating statistically significant reductions in the rate of moderate or severe COPD exacerbations compared with placebo. In addition, Tudorza® met its primary safety endpoint, demonstrating a favourable cardiovascular safety profile, with the time to patients experiencing a first major adverse cardiovascular event similar to placebo. Cardiovascular disease is the most common and significant comorbidity of COPD. A full evaluation of the ASCENT data is ongoing and the results will be submitted for presentation at a forthcoming medical meeting.
Next steps
Under the April 2017 collaboration established between Circassia and AstraZeneca, Circassia has responsibility for marketing Tudorza® in the United States, and AstraZeneca is responsible for conducting the product's clinical studies. Following the successful completion of the ASCENT study, AstraZeneca plans to file a supplemental New Drug Application (sNDA) with the United States Food and Drug Administration (FDA) to request inclusion of the trial data in Tudorza®'s label.
Steve Harris, Circassia's Chief Executive, said: "We are delighted with these positive Tudorza® clinical results, which underline the product's safety and efficacy, particularly in this important group of at-risk patients. We are highly encouraged with the progress we are making in our US commercial collaboration with AstraZeneca, and look forward to our partner filing for an extension to Tudorza®'s label in the coming months."
Steve Lewington, Global Medicine Leader, Respiratory, AstraZeneca said: "The ASCENT data demonstrate that Tudorza®, when added to background therapy, reduces exacerbation rates in patients with cardiovascular disease or risk factors and adds to the established efficacy and safety profile of aclidinium bromide. Based on these results, AstraZeneca plans to submit an sNDA for an expanded label for Tudorza® in the US."
About ASCENT
ASCENT was a double-blind, randomised, placebo-controlled, phase IV study, which enrolled over 3,600 patients with moderate to very severe COPD in the United States and Canada. The 36-month study evaluated the effect of Tudorza® (aclidinium bromide 400µg twice daily via Pressair® inhaler) on long-term cardiovascular safety and COPD exacerbations. The study had two primary outcome measures:
· Time to first Major Adverse Cardiovascular Event (MACE).
· Rate of moderate or severe COPD exacerbations per patient per year during the first year of treatment.
The study also had a number of secondary endpoints, including the rate of hospitalisations due to COPD exacerbations and the time to first MACE or other serious cardiovascular event of interest.
