In a striking demonstration of how the success of mRNA vaccines against COVID-19 has opened up the potential of the technology in cancer, mice that cleared a tumor after a single administration of an mRNA vaccine, also cleared a second tumor without receiving further immunization. This display of potent immunogenicity formed part of a head-to-head study of three different mRNA technology platforms in human papillomavirus (HPV)-16 associated tumors.
Global Health Drug Discovery Institute (GHDDI) has presented 3C-like proteinase (3CLpro) (SARS-CoV-2) inhibitors reported to be useful for the treatment of Middle East respiratory syndrome coronavirus (MERS-CoV), severe acute respiratory syndrome coronavirus (SARS-CoV) and SARS-CoV-2 infections (COVID-19).
Researchers from PDS Biotechnology Corp. and affiliated organizations have detailed the development and preclinical evaluation of recombinant protein vaccines formulated with enantio-specific cationic lipid R-DOTAP.
Insilico Medicine Inc. has received IND clearance from China's National Medical Products Administration (NMPA) for ISM-3312, an orally available 3CLpro inhibitor for the treatment of COVID-19. ISM-3312 has a novel molecular structure and was optimized from compounds designed by Chemistry42, Insilico’s generative chemistry AI platform.
An international team of researchers has created two bat stem cell lines that reveal an unusual number of viral sequences in bat cells compared with those of other mammals. Writing in an article posted online Feb. 21, 2023, in Cell, the scientists suggested that the unusual amount of viral genetic material found in the bat stem cells could explain why these mammals are largely unaffected by most viral infections, despite being able to transmit them.
The emergence of new variants of concern (VOCs) of SARS-CoV-2 may limit the efficacy of monoclonal antibodies and vaccines currently used in the clinic.
Thylacine Biotherapeutics Inc. has entered into a license agreement with Columbia University for worldwide exclusive rights to develop and commercialize a novel antiviral peptide platform invented and refined at Columbia.
Tonix Pharmaceuticals Holding Corp. has exercised an option to obtain an exclusive license from Columbia University for the development of a portfolio of fully human (TNX-3600) and murine (TNX-4100) monoclonal antibodies for the treatment or prophylaxis of SARS-CoV-2 infection.
