      Sharing a few threads on whether molnupiravir (new antiviral on the cusp of approval) risks generating new variants because the mutations it induces may, rarely but possibly, not kill the virus but generate viable variants instead. Many on the FDA panel who voted no raised this.https://twitter.com/CT_Bergstrom/status/1467611446053851145 …

      1. The FDA recently approved Merck's new COVID treatment, an antiviral known known as molnupiravir. The drug works by mimicking the cytidine and uridine nucleosides and thereby inducing frequent mutations in replicating virus.

      Another thread on the risk of sublethal mutagenesis (on the virus, not the human!) from molnupiravir:https://twitter.com/michaelzlin/status/1464424333246447620 …

      In conclusion, it would be highly irresponsible to approve molnupiravir unless the possibility of sublethal accelerated viral mutagenesis is thoroughly addressed and satisfactorily rejected, especially within the target population of patients at risk of hospitalization.

      TODAY at #Virological: throughout the #COVID19 pandemic, there has been a tendency to underestimate the potential of #SARSCoV2 to mutate and adapt. As the @US_FDA meets Tuesday to discuss #molnupiravir, @sarperotto and I fear another oversight.🧵 1/15 https://virological.org/t/mutagenic-antivirals-the-evolutionary-risk-of-low-doses/768 …

      This is Dr. Hildreth on the FDA advisory phrased it after the vote. (He wasn't the only one on the panel to raise the issue).https://twitter.com/JamesEKHildreth/status/1465806607909064705 …

      FDA AMDAC has voted 13 yes, 10 no for EUA for Merck's molnupiravir COVID-19 drug. I voted no. Inclusive data on mutagenic potential and concerns over generating troublesome SARS-CoV2 variants were not addressed to my satisfaction. Drug has modest 30% reduction in COVID-19 risk.

      One question I have is what happen with patience non-compliance? The pill is supposed to be taken over five days, every 12 hours at home (I think 40 pills total). There's going to be a lot of incomplete regimens in this scenario. How does this affect this risk?

      (Also, the trial had two phases and the drug had *zero* efficacy in the second phase which is really weird. It suggests regression to the mean so perhaps there is little to no benefit after all. Seems worth a longer study, but that's a separate question).

      Overall, we have multiple scientists raising the alarm that a new drug may end up generating new variants, many on the FDA panel voting no citing that very concern, and real questions on whether there's any benefit—already on the low side as claimed. Seems worth taking seriously.

      Has there been any further information on the pfizer antiviral drug?
