BioVaxys Bioproduction Partner WuXi Biologics Completes Synthesis Of Recombinant SARS-CoV-2 s-proteins for BVX-0320 and CoviDTH Programs

VANCOUVER,BC,Sept. 14,2021 --BioVaxys Technology Corp. (CSE: BIOV) (FRA: 5LB) (OTCQB: BVAXF)("BioVaxys"),announced today that global CDMO partner WuXi Biologics,has completed the synthesis of recombinant SARS-CoV-2 s-protein for BVX-0320,the company's COVID-19 vaccine candidate,and CoviDTH,its immunodiagnostic product. Both are headed for clinical trials,with BioVaxys having begun preparing an IND submission to the US Food and Drug Administration ("FDA") for a combined Phase I/II clinical study of CoviDTH as a diagnostic for evaluating T-cell immune response to SARS-CoV-2.

Under the terms of theMarch 11th,2021 agreement,WuXi Biologics synthesized high yields of fully characterized,SARS-CoV-2 s-protein for BioVaxys' Good Laboratory Practice (GLP) preclinical safety study of its CoviDTH which will begin this month. In its official Written Response in July to the Company's request for a Pre-IND Type B review of CoviDTH,the FDA has indicated that BioVaxys' planned animal toxicity study is discretionary and not required for IND submission. However,the Company is continuing with this study of CoviDTH as it does not interfere with the IND submission and may in fact provide useful data.

BioVaxys President & Chief Operating Officer Kenneth Kovan commented that "The production of the recombinant s-protein using WuXi Biologics' proprietary cell expression system is a significant milestone for Biovaxys,as we not only have a high production yield of protein,but also now have the ability and know-how to produce protein in large scale with the level of purity,consistency and protein characterization required by the FDA for our clinical studies and commercial-scale yields."

For greater certainty,BioVaxys is not making any express or implied claims that it has the ability to treat the SAR-CoV-2 virus at this time.
