Stockholm, April 3, 2024 - Chiesi, the international, research-focused biopharmaceuticals and healthcare group (Chiesi Group), has started a long-term phase III clinical safety trial for the new carbon minimal inhalers platform, replacing the current hydrofluorocarbon propellant (HFC 134a) with a new, low global warming potential propellant (HFC 152a).
Chiesi has already completed two short term clinical trials assessing safety of the new propellant[1], plus clinical pharmacology studies on the new carbon minimal fixed combination of an inhaled corticosteroid (ICS), and a long-acting bronchodilator (LABA). These studies collectively provided reassuring evidence of the similar performance and tolerability of the new formulation when compared to the current one for patients with asthma and COPD.
This milestone follows successful completion of similar studies in July 2022 with a fixed triple combination.
In 2019 Chronic obstructive pulmonary disease (COPD) is the third leading cause of death worldwide, causing 3.23 million deaths[2]. In the same year, Asthma affected an estimated 262 million people causing 455 000 deaths[3]. Many COPD and asthma patients depend on pMDIs for treatment. However, there's debate about how much pMDIs contribute to global warming. Efforts are underway to reduce their environmental impact[4].
The development of the carbon minimal inhalers platform aims at enabling Chiesi to reduce emissions related to current products by up to 90%, with significant reductions expected both in terms of direct emissions (production processes) and indirect ones (use of pMDIs) for the Company. This is a key step to achieve Net Zero greenhouse gas emissions by 2035 while preserving asthma and COPD patients’ needs.
“At Chiesi, we strongly believe that patients should not have to bear the responsibility of environmental impact when considering treatment options that affect their health. The conclusion of these additional studies and the start of the phase III trial marks a significant milestone for us in the development of a platform of new carbon minimal inhalers”, stated Giuseppe Accogli, CEO of Chiesi Group. "We are confident that we can deliver carbon minimal solutions to patients without compromising safety, usability or efficacy”.
International guidelines for the treatment of both asthma and COPD support the concept of choosing the right medication for the patient to reduce their risk of severe exacerbations[5].
"We are dedicated to developing inhalers that meet patient needs while minimising environmental impact. By addressing climate change, one of the root causes of respiratory illness, we can benefit patients and the planet simultaneously,” Accogli continues. “There should be no compromise between the two."
