Akston Biosciences Doses First Subjects in Phase II Clinical Trial of Second Generation Protein Subunit COVID-19 Vaccine

  • First phase II subjects receiving AKS-452, COVID-19 vaccine candidate in a Dutch trial
  • New data shows vaccine is stable for at least six months at 25 degrees Celsius (77 ° Fahrenheit)
  • Readings expected in the third quarter of 2021

BEVERLY, MA, USA I August 5, 2021 I Akston Biosciences Corporation, a developer of new classes of biological therapeutics, today announced that the first participants have been assayed in an open-label Phase II trial of AKS-452, its COVID-protein subunit vaccine candidate. 19.

Fifty-two volunteers will receive one- or two-dose regimens as part of the phase II trial at the University Medical Center Groningen (UMCG), one of the largest hospitals in the Netherlands. The trial is managed by TRACER Europe BV, a contract research organization (CRO) specializing in accelerated clinical trials.

The Phase I trial showed AKS-452 to be safe and well tolerated. Most importantly, AKS-452 produced a 100% seroconversion rate in the single-dose 90 microgram regimen, as well as the two-dose 45 microgram regimen.

“As early as Phase I, we know that AKS-452 has shown limited side effects, comparable to currently registered COVID-19 vaccines,” said Schelto Kruijff, MD Ph.D., principal investigator of the trial. at the UMCG. “New data that this vaccine candidate is stable at room temperature for at least six months makes it ideal for countries like Malawi and Kenya, where I volunteer, as it can be transported and stored for months without refrigeration. . “

AKS-452 has been shown to be stable for at least six months at 25° Celsius (77° Fahrenheit) and maintains its potency for a month at 37° Celsius (99° Fahrenheit).

“Prolonged shelf-life stability, clinical data showing that a single injection of the 90 microgram dose provides 100% seroconversion at significantly higher titers than COVID-19 positive convalescent serum samples, and the ease of manufacture compared to currently approved vaccines, indicate that our 2sd The generational vaccine has the potential to more easily protect the health of populations around the world from COVID, ”said Todd Zion, Ph.D., president and CEO of Akston Biosciences.

Prospective volunteers can still register to participate in the study and receive AKS-452, a subunit protein vaccine, a type of vaccine that has been used safely for decades, and does not include the technology of the MRNA, viral vectors or a weakened SARS-CoV. -2 viruses. All will receive the vaccine and none will receive a placebo. To find out more, click here: https://www.umcg.nl/-/medisch-wetenschappelijk-onderzoek/act-studie.

Gerard Metselaar said he felt lucky to be able to participate in Phase I: “I am living proof that this vaccine is effective,” he said. Because of the study, “I was vaccinated long before anyone in my age group. Although it was a great feeling, I got the greatest satisfaction knowing that it will help so many other people get closer to their vaccination. “

About the Phase II clinical trial

The Phase I / II clinical trial, an open-label study, evaluates a total of 112 healthy volunteers aged 18 to 85 years to determine safety, tolerability and immune response; Phase II participants will receive either a dose of 90 micrograms or two doses of 45 micrograms 28 days apart.

About AKS-452

Based on Akston’s proprietary Fc fusion protein platform, AKS-452 is a CoV-2 protein subunit vaccine candidate designed to induce a mixed Th1 / Th2 immune response in patients against the binding domain at the receptor (RBD) of the novel spike protein of the coronavirus. Being the primary locus of infection, RBD is highly conserved among mutated forms of the virus, and preclinical studies have demonstrated robust neutralization of antibodies to the Alpha and Beta variants. The vaccine was designed to use standard, inexpensive antibody manufacturing techniques, so that a single production line could be able to produce over a billion doses per year in existing factories around the world.
