Akston Biosciences and LakePharma have established a strategic partnership under which the latter will manufacture the former’s adjuvated COVID-19 vaccine candidate (AKS-452), which is scheduled to begin Phase 1/2 clinical testing later this month.
AKS-452 is the most advanced COVID-19-specific Fc fusion protein vaccine in commercial development and is engineered to induce or boost a Th1/Th2 mixed immune response in patients against the Receptor Binding Domain (RBD) of the novel SARS-CoV-2 coronavirus spike protein.
The inherent nature of this construct provides a unique combination of benefits compared to nucleic acid, viral-vectored, and inactivated virus vaccines.
Unlike other vaccines that must be kept refrigerated or even deep-frozen for transport and storage, AKS-452 has been shown to be shelf-stable for weeks at up to 37 degrees Celsius (95°F). This greatly simplifies distribution and is critically important for vaccinating the billions of people not served by sophisticated and costly cold-chain transportation.
Akston has engineered AKS-452 to use conventional antibody manufacturing techniques, such that with multiple batches over one year, a single 2,000-liter production train would be capable of producing over one billion doses.
“Our objective is to provide a practical solution to the problem of vaccinating and, if need be, boosting the immunity of people all over the world against the SARS-CoV-2 virus,” said Todd Zion, President & CEO of Akston Biosciences.
“Our team realised early on that our fusion protein platform could be used to design a vaccine that checked all the boxes – transportable at ambient temperatures, produced at very low cost, and suitable for repeated dosing if immunity wanes.
“Partnering with LakePharma gives us great confidence that we can ramp up quickly to deliver large quantities of AKS-452 on a commercial basis.”
Hua Tu, President and CEO of LakePharma, said: “We bring three critical components to this partnership: our experience in making SARS-CoV-2 proteins, our stable CHO-GSN technology, and most importantly, the use of the cGMP manufacturing suite in our Hopkinton, MA facility.
“We have worked with Akston and its fusion protein therapeutics since 2015, and this experience means we can transition AKS-452 into large-scale production very rapidly.”
