[{"type":"text","content":"PDS0202 (Infectimune® + COBRA influenza antigens) vaccination also prevented illness/weight loss Vaccine protected against replication of the virus in the lungs of ferrets after challenge with the H1N1 virusData from Cleveland Clinic’s Ted Ross Lab presented at the 9th ESWI Influenza Conference PRINCETON, N.J., Sept. 20, 2023 (GLOBE NEWSWIRE) -- PDS Biotechnology Corporation (Nasdaq: PDSB) (PDS Biotech or the Company), a clinical-stage immunotherapy company developing a growing pipeline of targeted cancer immunotherapies and infectious disease vaccines based on the Company’s proprietary T cell activating platforms, today announced its investigational universal influenza vaccine PDS0202 demonstrated active neutralization across multiple influenza viruses. The vaccine also provided protection against infection after challenged with high doses of the H1N1 virus in ferrets not previously exposed to flu. The data were presented in an oral lecture at the 9th European Scientific Working Group on Influenza (ESWI) Conference in Valencia, Spain by James Allen, PhD, from the Cleveland Clinic laboratory of renowned influenza expert, Ted Ross, PhD. “We are encouraged that PDS0202 has demonstrated activity in generating protective hemagglutination inhibition assay (HAI) antibody responses in pre-immune ferret studies, which are the gold standard in influenza vaccine testing. In addition to active neutralization of various influenza strains, the data demonstrated that PDS0202 prevented illness, weight loss and importantly protected the lungs of vaccinated animals from H1N1,” said Dr. Ross. “In humans, we expect PDS0202 to elicit a similar or more broadly reactive antibody profile due to humans having broader exposure to influenza and thus the recall of a more diverse population of memory B cells than the animals evaluated in our preclinical studies.” H3N2 HAI ResponseVaccination with PDS0202 Provides broadly effective HAI antibody responses (minimum 1:40 ratio) across multiple strains of the H3N2 virus including Swtiz/13 and Kan/17 demonstrating the broad reactivity of the novel COBRA proteins. Similar results were demonstrated against multiple strains of the H1N1 virus.
