SUNNYVALE, Calif., May 30, 2024 /CNW/ - Willow Biosciences Inc. ("Willow") (TSX: WLLW) (OTCQB: CANSF), a leading biotechnology company focused on revolutionizing industrial manufacturing of pure, consistent, and sustainable ingredients, announces a multi-product development and licensing partnership with Laurus Labs ("Laurus") (Bombay Stock Exchange Code: 540222; LAURUSLABS-IN: National Stock Exchange of India), a leading research-driven pharmaceutical and biotechnology company with a $3.9 billion market cap that serves global pharmaceutical companies and offers CDMO services. Laurus has commercialised 80+ products since its inception. Laurus has nine manufacturing facilities including fermentation capabilities.

Through this partnership, Willow will leverage its AI-driven technology platform and extensive experience in enzyme, strain, and process engineering to deliver biobased processes for high-value Active Pharmaceutical Ingredients (APIs) with existing markets, including Willow's BioOxi^TM-based corticosteroid processes, for large scale manufacturing, sales, and distribution at Laurus. Willow and Laurus expect these first programs to reach commercial manufacture in 2025.

Under the terms of the collaboration, Willow expects to earn significant annual revenues in research & development and royalties, including $4.0 million in guaranteed research & development payments in year one. Upon commercialization of the APIs, Willow will receive an annual royalty based on worldwide sales.

Laurus recognized the need to employ more sustainable methods to manufacture its APIs with reduced cost and less waste and thus, identified Willow's expertise and, specifically, its AI-driven BioOxi platform, for developing transformative bioprocesses to key APIs. This new partnership will start with the continued optimization and scaling of Willow's BioOxi platform, along with development of new processes for targets within Laurus' API and other ingredient portfolios.

Willow's BioOxi biological hydroxylation platform solves for selective C-H hydroxylation at industrial scale – often referred to as one of the "Holy Grails" of chemistry. BioOxi-enabled biomanufacturing of ingredients can remove multiple chemical steps and significantly reduce cost and resources.

"We are excited to be partnering with Laurus Labs, one of the most respected and established pharmaceutical ingredient manufacturers in the world. This strategic partnership is the culmination of Willow's new focus on pharmaceutical ingredients and investment over the past two years," said Dr. Chris Savile, Willow's President & CEO. "We are proud our technology platform is being integrated with Laurus to support their commercialization of more sustainable, cost-effective products."

Commenting on the collaboration partnership, CEO of Laurus Labs Dr. Satyanarayana Chava said, "Willow has demonstrated through its bioengineering technology platform a unique capability to significantly reduce the cost of API production while enabling greater product availability. We look forward to a long and successful partnership, which we believe will further strengthen Laurus' strong reputation for market innovation."

With its largest agreement to-date, this multi-product agreement adds both near-term R&D and long-term commercial upside to Willow's already robust and growing pipeline of commercial opportunities in food, pharmaceuticals, and agriculture.
