DE – April 28th, 2022 – Cellvera, a US biopharmaceutical company, today reports a summary of recent studies demonstrating the efficacy of Favipriavir against several SARS-CoV-2 variants, including Delta and Omicron, and findings from the world’s largest meta-analysis. Cellvera, a company focused on discovering, developing, and commercializing antiviral therapies across a broad spectrum of infectious diseases, holds directly, or through its affiliates worldwide exclusive worldwide rights to Avigan 200mg (Favirpiravir) and higher strength formulations of the drug branded Qifenda 400MG and 800MG, a broad-spectrum oral antiviral treatment that targets COVID-19 and at least 12 other infectious diseases. Cellvera has developed and introduced the drug in several global markets since the start of the pandemic.
Favipiravir is a selective inhibitor of viral RNA-dependent RNA polymerase (RdRP) with potent antiviral activity against single-stranded RNA viruses, including coronaviruses. It targets the protein needed for the coronavirus to replicate, making it impossible for the virus to copy itself. The broad-spectrum antiviral drug is effective against 12 families of viruses, including Coronaviruses (COVID, MERS, SARS), Filoviruses (EBOLA, MARBURG), Flaviviruses (ZIKA, WEST NILE, DENGUE), RABIES, NOROVIRUS, and many others.
As novel strains of the SARS-CoV-2 virus continue to emerge, preliminary studies on SARS-COV-2 variants—Omicron and Delta—have shown that Favipiravir maintains its antiviral activity, demonstrating the inability of viruses to form resistance to Favipiravir even with prolonged exposure of virus-infected cells to the drug.[2]3 Favipiravir remains an invaluable asset for emergency preparedness strategies against this constantly evolving COVID-19 virus and other potential future pandemics.
On the international stage, the Thailand Disease Control Department (DDC) recently announced its official position on Favipiravir, stating that “the drug was effective in treating mild and moderate symptoms and numerous patients are given Favipiravir recovered and were discharged from hospitals.4 In patients administered Favipiravir, the clinical improvement rate was 79% after 14-days of monitoring, compared to a 32.2% improvement rate in the control group.
Cellvera recently announced their support of the UK government and the University of Oxford in their national priority platform trials of COVID-19 treatments. Platform Randomised Trial of Treatments in the Community for Epidemic and Pandemic Illnesses (PRINCIPLE) is one of the world’s most extensive trials currently in a community setting, seeking treatments for outpatient use. In April 2021, the University of Oxford announced that Favipiravir would be investigated in the UK; a trial was set up with the intention that drugs shown to have a clinical benefit could be rapidly introduced into routine National Health Service (NHS) care. However, except for Favipiravir, the other three drugs selected for this trial were discontinued due to futility within weeks, with a continued expansion of the number of patients being administered Favipiravir.
Since 2014, Favirpiravir has been extensively studied and evaluated in 40 clinical trials before the COVID-19 pandemic. In some prior trials, like PRESECO in the US, Favipiravir did not demonstrate efficacy due to insufficient dosage available to patients or late treatment. At the same time, the mounting evidence from the world’s large meta-analysis points to a proven efficacy of Favipiravir against SARS-COV-2 and its variances. However, Favipiravir continues to demonstrate significant clinical improvements and promotes enhanced viral clearance in mild-to-moderate COVID-19 patients as the data from several clinical trials showed that:
