Bio-Thera Solutions Announces Details of Poster Presentation of a Highly Thermal Stable Recombinant Bivalent Nanoparticle Vaccine Containing Spikes of SARS-CoV-2 Omicron and Delta at Vaccine Summit 2022

Bio-Thera Solutions, Ltd. (SH: 688177), a commercial-stage biopharmaceutical company, announced today the details of its poster presentation at the Vaccines Summit 2022, being held from October 11-13 in Washington D.C. Bio-Thera will present research and preclinical results of a highly thermal stable recombinant bivalent nanoparticle vaccine containing spikes of SARS-CoV-2 Omicron and Delta, showing high immunogenicity and potentially offering broad cross-protection against ever evolving Covid-19 variants.

Preclinical studies showed that the candidate vaccine was highly immunogenic in both mice and rats, could elicit robust broadly cross-reactive neutralizing antibodies against all major SARS-Cov-2 variants. The candidate vaccine protected all the K18-hACE2 transgenic mice challenged with lethal dose of Omicron variant from body weight loss and death, with undetectable live virus in their lung tissues. This vaccine candidate leverages the self-assembled stable nanoparticles, is formulated with Bio-Thera’s proprietary formulation platform, and is highly stable across a broad range of temperature from freezing to over 40-degree Celsius. This vaccine candidate thus could be a valuable strategy for vaccination against the ever-changing SARS-CoV-2, especially for the remote and low-income regions in the globe.

Details of the presentation are as follows:
