IPA's Human Anti-SARS-CoV-2 Therapeutic Antibodies Demonstrate Synergistic Neutralization

VICTORIA, BC, July 31, 2020 /PRNewswire/ - IMMUNOPRECISE ANTIBODIES LTD. (the "Company" or "IPA") (TSXV: IPA) (OTCQB: IPATF) (FSE:TQB2), a provider of best-in-class therapeutic antibody capabilities, is pleased to announce that additional characterization of a subset of fully human, therapeutic antibodies, already shown to have potent neutralizing activity, are exhibiting enhanced neutralization upon combinatorial (dual antibody) testing.

Previously, IPA confirmed the identification of numerous therapeutic antibodies derived from multiple species (human, llama, Ligand's humanized OmniRat, and wild-type rabbits) demonstrating potent, in vitro neutralizing activity. These functional antibodies were discovered using the Company's DeepDisplay(TM) phage technology, B Cell Select(TM) and Single Step Hybridoma platforms. The functional antibodies discovered to date bind to multiple regions of the SARS-CoV-2 spike protein. The purpose of this update is to announce the Company's most recent advancements regarding further characterization of the first subset of antibodies, namely, those discovered using the Company's DeepDisplay(TM) phage technology that demonstrate binding to the SARS-CoV-2 spike Receptor Binding Domain. The Company has confirmed that a subset of six of these antibodies, falling into three different epitope bins, were analyzed in combination, and resulted in clear synergistic effects, meaning their activities are in fact enhanced in combination studies resulting in near complete neutralization of SARS-CoV-2 pseudovirus infection.

"As we characterize IPA's approximately seventy-five functional lead candidates it is clear that our extensive program has generated therapeutics with broadly diverse profiles, providing substantial opportunities for multi-epitope targeted strategies," stated Jennifer Bath, CEO of IPA. "After selecting approximately sixteen hundred antibodies with the most desirable binding profiles to various spike protein formats, we down-selected our leads based on very specific criteria, all of which are key in our ongoing determination of ideal candidates."

As the Company continues to screen its repository of functional antibodies, it advances the identification of synergistic neutralizing antibody pairs, which they believe will set a new precedent in the on-going fight against COVID-19.

The Company continues to further analyze multiple, additional, subsets of antibodies, including neutralizing antibodies demonstrated to bind to the S1 and S2 domains of the SARS-CoV-2 spike protein. Furthermore, the Company has begun steps for the expression of the lead antibodies for pre-clinical and clinical manufacturing.

Jennifer Bath, Ph.D., Chief Executive Officer of ImmunoPrecise, has reviewed and approved the scientific disclosure of this news release.

The Company's lead antibodies against COVID-19 (or SARS-CoV-2) have not yet been studied in human clinical trials and, as a result, IPA is not making any express or implied claims that its products have been proven to have the ability to eliminate, cure or contain COVID-19 (or SARS-CoV-2) at this time.
