GSK announces major step towards sustainability ambitions with advancement of low carbon Ventolin programme to Phase III trials.

Published:22nd Nov 2023

GSK plc announced it will start Phase III trials of a low carbon version of its metered dose inhaler (MDI), Ventolin (salbutamol), using a next generation propellant, in 2024

If successful, it has the potential to reduce greenhouse gas emissions from use of the inhaler by approximately 90%, significantly contributing to GSK’s ambitious net-zero climate targets.

Thirty-five million patients with respiratory conditions around the world rely on this inhaler as their rescue medication. However, it accounts for close to half (49%) of GSK’s carbon footprint, as well as contributing to the carbon footprint of global health systems. Significantly reducing the carbon footprint of the propellant in the inhaler is a key milestone in the company’s pathway to net zero.

GSK is investing in a R&D programme to redevelop the inhaler by transitioning to a lower carbon propellant. The next-generation propellant, which has been under technical development for several years, has been tested extensively to ensure suitability for MDIs and patient use. Recent data from early clinical trials has supported the decision to progress to phase III and dosing of first patients is planned in the first half of 2024. If successful, regulatory submissions will begin in 2025.

GSK Chief Executive Officer, Emma Walmsley, said: “As countries work to decarbonise their health systems, companies have an important role to play – and addressing the carbon emissions from inhalers is a key part of this. Harnessing our deep respiratory expertise, we have developed an innovative low carbon inhaler and I am delighted that we are now progressing this programme into Phase III trials. If successful this could lead to regulatory submissions in 2025, supporting the health of asthma and COPD patients and making a significant positive impact on our transition to a more environmentally sustainable future.”
