Applied DNA, EvviVax, and GVS Receive Regulatory Approval to Conduct Veterinary Clinical Trial for Linear COVID-19 Vaccine Candidate
Applied DNA Sciences (NASDAQ: APDN) has received approvals from New York and U.S. agricultural departments for a veterinary trial of its LinearDNA COVID-19 vaccine candidate, aimed at domestic felines. This redesigned trial allows faster data collection and aims for a USDA APHIS conditional license for commercial sales after demonstrating safety and immunogenicity. The trial, beginning within 90 days, will recruit a smaller group of healthy felines to assess the vaccine’s effectiveness, responding to serious COVID-19 risks in animal reservoirs and potential spillover effects on human populations.
- Received New York and U.S. Department of Agriculture approvals for veterinary trial.
- Accelerated trial design aims for a conditional USDA license for commercial sales.
- Previous studies yielded strong antibody and T-cell responses in similar vaccine candidates.
- Dependence on achieving trial endpoints to apply for conditional license.
- No guarantee of safety and efficacy established for the vaccine candidates.
STONY BROOK, N.Y.--(BUSINESS WIRE)--Applied DNA Sciences, Inc. (NASDAQ: APDN) (“Applied DNA” or the "Company"), a leader in Polymerase Chain Reaction (PCR)-based DNA manufacturing, EvviVax, S.R.L. (“EvviVax”), a spin-off of Takis Biotech with expertise in engineered veterinary cancer immunotherapy and targeted vaccines, and Veterinary Oncology Services at Guardian Veterinary Specialists (GVS), a multi-specialty veterinary hospital, announced the receipt of approvals from the New York State Department of Agriculture and Markets and the U.S. Department of Agriculture on an advanced clinical strategy to conduct a previously reported, New York State-based, veterinary trial of a lead LinearDNA™ COVID-19 vaccine candidate. The vaccine candidate is jointly developed by Applied DNA and EvviVax.
Applied DNA, EvviVax, and GVS also announced a redesign of the veterinary trial to allow for an acceleration of the lead candidate’s development path with the end goal of applying for a U.S. Department of Agriculture Animal and Plant Health Inspection Service (USDA APHIS) conditional license to enable commercial veterinary sales for domestic felines.
The goal of the trial remains to evaluate the vaccine candidate as a strategy for the prevention of SARS-CoV-2, the virus that causes COVID-19, in feline companions of humans that would mitigate the animals as a potential reservoir for infections in humans. Domestic felines are a known COVID-19 reservoir and can transmit the virus to other felines. No transmission back to humans has been documented, though the scientific possibility remains given the virus’s zoonotic origin. The trial will take place at GVS in Brewster, N.Y., and is expected to begin within the next 90 days.
The trial will now recruit a smaller number of healthy domestic feline companion animals that will receive two doses of the vaccine candidate and follow the enrolled cohort for up to six months. The trial’s primary endpoint is to demonstrate the safety and immunogenicity (detection of neutralizing antibodies and T-cell response) of the vaccine candidate in domestic felines. The vaccine candidate previously yielded strong antibody and T-cell responses even at very low doses in mice.
Trial Supervising Investigator and Diplomate of the American College of Veterinary Internal Medicine, Dr. Joseph Impellizeri, of GVS, stated, “By studying the immune response after immunizing an important host that resides with human counterparts, we hope to understand better the potential clinical response against the virus using a specially designed vaccine and delivery system that may translate to both human and animal protection.”
Accelerated Development of Clinical Path
The redesigned trial allows for immunologic data to be gathered faster across a smaller cohort that would also support the near-concurrent pursuit of a parallel trial (the “proposed trial”) currently being finalized to advance further data by challenging an additional cohort in a controlled environment with the lead vaccine candidate. Upon seroconversion, the vaccinated felines would then be placed among an infected COVID-19 feline cohort. The rates of transfer of the infection among the vaccinated cohort will be studied with a planned endpoint of revealing the vaccine candidate’s overall efficacy against active disease. The data from the redesigned and proposed trials may also provide additional support for requisite toxicology and bio-distribution studies to potentially initiate human SARS-CoV-2 vaccine candidate trials.
On the assumption that both trials’ primary endpoints are met, the Company and EvviVax expect to apply for a USDA APHIS conditional license (9 CFR 102.6) for a LinearDNA COVID-19 vaccine candidate for domestic felines. Conditional licensure is afforded to products that meet emergency needs, such as the COVID-19 outbreak, and potentially accelerates the vaccine candidate’s time-to-market.
“In accelerating our vaccine development program for veterinary application, we seek to elevate our work with EvviVax in the emerging field of SARS-CoV-2 susceptibility in animals,” said Dr. James A. Hayward, president and CEO, Applied DNA. “With the initiation of the redesigned veterinary trial, we progress towards potentially commercializing our lead LinearDNA vaccine candidate for use on domestic felines while also generating valuable complementary data for potential human COVID-19 vaccine candidate trials and charting a possible development path to other animals, such as mink. The virus’s impact on farmed mink populations globally has been especially devastating and has resulted in the collapse of Denmark’s
