Partnership will support the companies’ ongoing R&D collaboration

Sunflower Therapeutics, a public benefit corporation transforming global access to protein manufacturing capacity for diverse applications, today announced that SK bioscience, a global innovative vaccine and biotech company committed to promoting human health from prevention to cure, has participated in Sunflower’s simple agreement for future equity (SAFE), a flexible agreement providing future equity rights without immediate valuation, with a $2M subscription to solidify their support for the companies’ ongoing research and development R&D collaborations.

The subscription builds on Sunflower and SK bioscience’s existing collaboration to develop an efficient manufacturing process for an accessible human papillomavirus (HPV) vaccine using the alternative protein expression host Pichia pastoris. Through their partnership, SK bioscience is leveraging Sunflower’s expertise in the development of integrated biomanufacturing processes using alternative hosts in the development and manufacturing of accessible, clinically relevant vaccines for combatting public health crises such as HPV and cervical cancer.

“In this time where various infectious diseases threaten humanity, vaccine sovereignty is the key to protecting the safety of our people and enhancing national competition,” said Jaeyong Ahn, CEO of SK bioscience. “We are excited to deepen our relationship with Sunflower Therapeutics and make an impact on global health as we continue to develop efficacious, safe and cost-effective vaccines.”

Sunflower’s cutting-edge approach uses continuous fermentation, an entirely new way to make virus-like particles (VLPs) and has been proven to be five to ten times more effective in space-time yields for VLPs than fed-batch fermentation. Through the companies’ collaboration, Sunflower is evaluating the potential for cost-effective manufacturing in P. pastoris using Sunflower’s Daisy Petal^TM perfusion bioreactor system, a laboratory-scale, automated manufacturing system for the integrated production of purified protein bulk using microbes.

“Our accessible, cutting-edge protein manufacturing solutions are moving the needle by reimagining the biologic development process,” said Dr. Kerry R. Love, Founder, CEO and President of Sunflower Therapeutics. “We’re thrilled by SK bioscience’s expanded support and look forward to democratizing and supporting product development for vaccine producers across the globe with our next-generation manufacturing technologies, coupled with our thoughtful, resourceful services.”
