The announcement comes just days after the regulator said its CHMP scientific committee had begun to look at the first batch of data from AZ’s rival. These studies suggest BNT162b2 triggers the production of neutralising antibodies and T-cells that target SARS-CoV-2, the coronavirus that causes COVID-19.
InteRNA is focusing on the development of gene-silencing drugs based on microRNA, naturally occurring, non-coding strands of RNA that are thought to regulate gene expression in cells.
AT-527 works by blocking the viral RNA polymerase enzyme needed for viral replication. But the findings of the latest phase 3 study , EMPACTA, could change that after Roche said it plans to share results with the FDA and other regulators to get its label expanded on the basis of the latest results.
But the tragic events of 2020 have meant these companies have become household names as their trailblazing mRNA vaccines became the first to be approved by regulators against the COVID-19 scourge. Their technology is based on synthetic messenger RNA – short for ribose nucleic acid – which is a short transcript of a longer DNA code.
Drugs harnessing the potential of modified RNA, antisense and siRNA oligonucleotides, antibody–drug conjugates and nanomedicines will become as important as today’s ‘small molecule’ drugs, reaching potential market values into the hundreds of billions – if the potential can be realised through innovation support and industry collaboration.
” But the Pfizer and Moderna vaccines are designed to not only target the spike protein, but to promote the creation of antibodies that will attack it in several different ways, Salvatore said. “The height of the antibody response may be somewhat proportional to how sick you are in the beginning.
But the companies said their refined antigen formulation induced a strong immune response in individuals agesd18 to 95, with neutralizing antibodies comparable to those found in patients after recovery from SARS?CoV?2 And if the results are positive, the companies expect to seek approval from regulators in the fourth quarter.
The variant that originated in South Africa carries a mutation in the Spike protein that has been shown to reduce antibody recognition and could therefore affect efficacy of new vaccines. These will be encoded in messenger RNA (mRNA) formulated with the laboratory’s NLP technology before injection.
New oral therapies join the existing monoclonal antibody cocktails and include molnupiravir (Lagevrio, Merck) and a combination of the new antiviral nirmatrelvir with the HIV antiviral ritonavir (Paxlovid, Pfizer). New COVID-19 treatments will also be available in 2022, but they are not a panacea.
Novartis has revealed that the FDA has accepted its resubmission for cholesterol-lowering drug Leqvio – rejected unexpectedly by the US regulator last year – and has set a new action date of 1 January 2022.
