Currently in Phase 3 clinical testing in the United Kingdom for the prevention of COVID-19, NVX-CoV2373 is a recombinant protein vaccine adjuvanted with Novavax’ proprietary Matrix-M to enhance the immuneresponse. The company will work with Medsafe, New Zealand’s regulatory agency, to obtain product approvals as needed.
Researchers from the Laboratory of Bacteriology at The Rockefeller University have now found that bacteria sense phages by a defensive response named CBASS (cyclic oligonucleotide-based antiphage signalling system) which detects viral RNA. In bacteria , cGAS-like cyclases are central parts of the CBASS immuneresponse.
Strong Th1 cell-mediated immuneresponses were also observed for the vaccine candidates with either adjuvant. We are encouraged by the high level of neutralizing antibodies in combination with the strong Th1 response which we believe could play an important role in controlling infection. S-Trimer is intended to be adjuvanted.
The data, published today in Nature Medicine , demonstrated that the Company’s investigational adenovirus serotype 26 (Ad26) vector-based vaccine elicited an immuneresponse as demonstrated by “neutralizing antibodies” and prevented severe clinical disease – including weight loss, pneumonia and mortality – in Syrian golden hamsters upon challenge.
Another promising avenue is the use of technologies like RNA interference and gene editing, which allow scientists to turn off the production of certain proteins altogether. These methods could bypass the need to directly target these proteins with traditional drugs.
Its primary challenges include: Production Delays : The time-intensive process of expanding TILs to therapeutic quantities poses logistical hurdles. Response Rates : To date, approximately 30% of patients are achieving objective responses, indicating considerable room for improvement.
Draft guidance on potency assays for CGT products garners extensive stakeholder input Late last year, the FDA published a draft update to its 2011 guidance on potency assays for cell and gene therapy products, unveiling a major shift in approach to the issue.
