GSK plc and CureVac N.V. have restructured their existing collaboration into a new licensing agreement, allowing each company to prioritize investment and focus their respective mRNA development activities.

Since 2020, GSK and CureVac have worked together to develop mRNA vaccines for infectious diseases. Through this collaboration, GSK and CureVac currently have vaccine candidates for seasonal influenza and COVID-19 in Phase 2 and avian influenza in Phase 1 clinical development. All candidates are based on CureVac’s proprietary second-generation mRNA backbone. Data generated to date for these candidate vaccines are promising and demonstrate their potential to be best-in-class new vaccines.

Under the terms of the new agreement, GSK will assume full control of developing and manufacturing these candidate vaccines. GSK will have worldwide rights to commercialize the candidate vaccines. The agreement represents the latest step in GSK’s ongoing investment in vaccine platform technologies, matching the best platform to each pathogen to develop best-in-class vaccines. GSK continues to develop and optimize its mRNA capabilities through investments and partnerships, including in AI/ML-based sequence optimization, nanoparticle design and manufacturing.

CureVac will receive an upfront payment of €400 million and up to an additional €1.05 billion in development, regulatory and sales milestones and tiered royalties in the high single to low teens range. The new agreement replaces all previous financial considerations from the prior collaboration agreement between GSK and CureVac. CureVac further retains exclusive rights to the additional undisclosed and preclinically validated infectious disease targets from the prior collaboration together with the freedom to independently develop and partner mRNA vaccines in any other infectious disease or other indication.

Tony Wood, Chief Scientific Officer, GSK said: “We are excited about our flu/COVID-19 programs and the opportunity to develop best-in-class mRNA vaccines to change the standard of care. With this new agreement, we will apply GSK’s capabilities, partnerships and intellectual property to CureVac’s technology, to deliver these promising vaccines at pace.”

Alexander Zehnder, Chief Executive Officer, CureVac said: “The collaboration with GSK has been instrumental in developing promising, late clinical-stage vaccine candidates, leveraging our proprietary mRNA platform. This new licensing agreement puts us in a strong financial position and enables us to focus on efforts in building a strong R&D pipeline.”

Completion of the new agreement remains subject to certain antitrust and regulatory approvals and customary closing conditions.
