CHARLOTTE, NC, Feb. 22, 2022 /PRNewswire/ — Honeywell (Nasdaq: HON) today announced a commercial partnership with AstraZeneca (LON: AZN) to develop and bring to market next-generation respiratory inhalers that use near-zero global warming potential (GWP) propellants to treat asthma and chronic obstructive pulmonary disease (COPD).

As many as 384 million people suffer from COPD, a progressive respiratory disease, and 339 million children and adults suffer from asthma.1,2 Many of these patients are currently treated with metered-dose inhalers pressurized (pMDI) that can contribute to the footprint of respiratory care.

AstraZeneca, a global leader in the treatment of respiratory diseases, is working to integrate Honeywell’s Solstice® Air (HFO-1234ze cGMP) as a medical propellant, reducing pMDI greenhouse gas emissions by up to 99.9% compared to current inhaler propellants. Solstice Air is the only near-zero GWP non-flammable propellant available and in clinical development today for pMDIs.

A recently completed Phase I clinical trial of propellant HFO-1234ze in a pMDI containing budesonide, glycopyrronium and formoterol fumarate in healthy adults was positive, demonstrating a similar safety and tolerability profile and exposure systemic active ingredients compared to Breztri Aerosphere (budesonide/ glycopyrronium/ formoterol fumarate). AstraZeneca expects Breztri Aerosphere to be the first drug to transition to the next-generation pMDI platform, subject to regulatory approval.

Following these positive Phase I trial results, AstraZeneca will advance a commercial partnership with Honeywell to develop their triple combination therapy, Breztri Aerosphereusing Honeywell’s near-zero GWP thruster technology.

Pascal Soriot, Chairman and CEO of AstraZeneca, said: “We are making great strides in our ambition to be carbon zero in our global operations by the end of 2025 and carbon negative across our entire chain. value by 2030. Our collaboration with Honeywell demonstrates AstraZeneca’s commitment. to advance sustainable innovation in healthcare, with the goal of improving patient outcomes while reducing our environmental footprint.

“The work we are doing with AstraZeneca to develop a respiratory inhaler, with a new propellant with near-zero global warming potential, is extremely important both for the environment and for patients with respiratory problems,” said Darius. Adamczyk, chairman and CEO of Honeywell. “Our goal is to reduce carbon emissions from respiratory healthcare without restricting patient choice or risking improved health outcomes. This is just one example of how Honeywell is innovating to help our customers, like AstraZeneca, meet their environmental goals and stay focused on quality for their customers.”

Solstice Air is a breakthrough for pressurized metered dose inhalers (pMDIs). A non-flammable, low Global Warming Potential (GWP) alternative to hydrofluorocarbons, it does not deplete the ozone layer, is VOC-free (US EPA and CARB), with an ultra-low GWP close to 1. is the only new generation HFO. fuel-based propellant not currently subject to quota-based allocation under the recent 2020 American Innovation and Manufacturing (AIM).

Honeywell has invested a billion dollars in research, development and new capabilities for its Solstice technology, having anticipated the need for low-GWP solutions to combat climate change more than a decade ago. The product range, which helps customers reduce their greenhouse gas emissions and improve energy efficiency without sacrificing end-product performance, includes refrigerants for supermarkets, air conditioning for cars and trucks, blowing agents for insulation, propellants for personal and household care and solvents for cleaning. solutions.

Customers using Solstice technology have avoided the potential release of the equivalent of over 250 million metric tons of carbon dioxide into the atmosphere, equivalent to eliminating potential emissions from over 52 million cars for one year .

Honeywell is committed to achieving carbon neutrality in its operations and facilities by 2035. This commitment builds on the company’s track record of drastically reducing the greenhouse gas intensity of its operations. and facilities, as well as its decades of innovation to help its customers meet their expectations. environmental and social objectives. About half of Honeywell’s investment in new product introduction research and development is directed toward products that improve environmental and social outcomes for customers.
