NIAID Confirms IPA’s PolyTope TATX-03 Neutralizing Activity Against the Currently Spreading SARS-CoV-2 Variant BA.2.75

VICTORIA, British Columbia, September 14, 2022--(BUSINESS WIRE)--IPA (IMMUNOPRECISE ANTIBODIES LTD.) (the "Company" or "IPA") (NASDAQ: IPA) (TSXV: IPA), announced today that its subsidiary, Talem Therapeutics LLC ("Talem"), has shared positive results of a new study conducted by the National Institute of Allergy and Infectious Disease (NIAID), part of the National Institutes of Health (NIH), that has shown the continued resilience of PolyTope® TATX-03 in broadly neutralizing SARS-Co-V-2 variants, including two Omicron sublineages that had not been previously tested.

This NIAID-conducted pseudovirus-based study has reconfirmed the neutralizing activity of TATX-03 against the European variant (D614G mutant) of the parental virus and several previously tested variants, including Delta (B.1.617.2), and Omicron sublineages (BA.2, BA.4/5). Importantly, TATX-03 has now demonstrated its neutralizing activity against the currently spreading BA.2.75 variant. Maintained neutralizing potency was also confirmed for the Omicron sublineage BA.2.12.1, SARS-Co-V-2 variant that had not yet been screened in virus neutralization studies.

IPA’s Chief Scientific Officer (CSO), Dr. Ilse Roodink, stated: "We appreciate that our interactions with the FDA resulted in this collaboration with the NIAID. This division of the NIH is continuously screening clinical-stage antibody therapeutics for neutralizing potency towards emerging variants. We highly value this independent validation of the resilience of our PolyTope® TATX-03 product, further strengthening our position as we progress into clinical trials in humans."
