Business Wire

Key Highlights

  • Regulatory submissions for next-generation propellant pMDIs (pressurized metered-dose inhalers) across Chiesi's Single Inhaler Triple Therapy (SITT; or ICS/LABA/LAMA) and fixed double ICS/LABA combination (inhaled corticosteroid with a long-acting bronchodilator) range have been validated by Regulatory Agencies in Europe.

  • Transition to HFA‑152a, a next‑generation propellant classified as non‑PFAS* and with low global warming potential (GWP), aims to reduce the carbon footprint of Chiesi's pMDIs by up to 90% compared to current ones.1-3

  • Designed for a seamless transition for patients and HCPs, maintaining established efficacy, safety and usability and supporting continuity of care.4-8

  • The validation supports Chiesi's ambition to reach Net Zero† across its full value chain by 20359, following MHRA approval of Chiesi's beclometasone pMDIs formulated with HFA-152a.

PARMA, Italy, September 03, 2026--Chiesi Group, an international research-focused biopharmaceutical company and certified B Corp, today announces a further step in its Carbon Minimal Inhaler (CMI) journey with the validation of regulatory submissions in Europe for its SITT and ICS/LABA pMDIs.

The start of regulatory assessment in Europe marks a significant step towards Chiesi's transition to carbon minimal pMDIs across its respiratory portfolio, combining innovation with responsibility. This supports the Company's broader ambition to reduce the environmental impact of respiratory care, while enabling a seamless transition for patients and healthcare professionals. In July 2026, the UK Medicines and Healthcare products Regulatory Agency (MHRA) approved Chiesi's beclometasone pMDIs formulated with HFA-152a, marking the first UK approval of this next-generation propellant in a pressurised metered-dose inhaler.

Chiesi's pMDIs are transitioning to HFA-152a, a next-generation propellant classified as non-PFAS* and with low-GWP, designed to reduce the products' carbon footprint by up to 90% compared with current ones1-3, while maintaining established efficacy, safety, and usability.4-8

"Innovation in patient care and environmental responsibility are not a trade-off. Our next-generation carbon minimal pMDIs provide the same level of care, while reducing emissions of up to 90% compared to the ones in use today and at the same level of dry powder inhalers (DPI)," said Andrea Bizzi, Executive Vice President, Region Europe TOP 5 & Interim AIR Franchise. "These submissions are another step on our progression towards a full extrafine CMI portfolio across pMDIs and DPIs."
