Akston Biosciences Ends Vaccine Partnership with Stelis, Continues to Advance COVID Universal Booster EUA
- Akston has reclaimed all commercial rights to AKS-452, its room temperature stable COVID-19 vaccine
- Akston is continuing its progress to secure Emergency Use Authorization (EUA) in India and has begun working with a new CDMO to produce AKS-452
BEVERLY, Mass. and BANGALORE, India–(BUSINESS WIRE)–#VIE–Akston Biosciences Corporation, a developer of new classes of biologic therapeutics, announced today it has ended its AKS-452 licensing, manufacturing, and commercialization agreement with Stelis Biopharma Limited, an arm of Strides Pharma Science Ltd.
Akston has reclaimed all rights to AKS-452, a room temperature stable, low-cost, protein subunit COVID-19 vaccine. AKS-452 has completed a Phase II/III clinical trial in India, with data showing robust safety profile and a 91% seroconversion rate at Day 56. Volunteers in the study had antibody titers that persisted at statistically-significant high levels through six months, with serum showing protection against variants of concern, including Delta and Omicron.
Akston is now working with a new CDMO in India to produce the promising AKS-452 COVID “universal” booster vaccine.
The results of a Phase I/II randomized, open-labelled study in The Netherlands and published in Vaccine showed that seroconversion rates reached 100% with enhanced potencies of SP/RBD-ACE2 binding inhibition and live virus neutralization.
In a Phase II study in the Netherlands of AKS-452 as a “universal” booster vaccine, 93% of subjects previously vaccinated with Pfizer, Moderna, Johnson & Johnson (Janssen), and AstraZeneca vaccines showed an increase in neutralizing antibody titers after receiving a single dose. The average neutralization titers across all subjects increased 4-fold against the Wuhan strain and 5-fold against the Omicron variants at Day 28. There were no safety issues reported.
Todd Zion, Ph.D., President & CEO of Akston Biosciences, said, “I am confident that AKS-452 can attain Emergency Use Authorization (EUA) in India, especially as a ‘universal’ booster vaccine capable of increasing and broadening people’s immune response as their previous immunity wanes and new variants arise. We concluded that Akston and a different CDMO were better placed to move ahead the AKS-452 development plan at a rapid pace, so we reclaimed the rights.”
