FDA authorizes Pfizer's Covid treatment pill, the first oral antiviral drug cleared during the pandemic
Health
he Food and Drug Administration granted emergency authorization Wednesday to Pfizer’s Covid treatment pill, a major milestone that promises to revolutionize the fight against the virus.
The medication, which is recommended for people at a high risk of developing severe Covid-19, could be available to patients as early as this weekend. Pfizer CEO Albert Bourla told CNBC earlier this month the company has already shipped some of the pills to the U.S. so they can be prescribed as soon as the FDA authorization comes through. The Centers for Disease Control and Prevention is expected to quickly follow suit with its seal of approval, authorizing its distribution.
The FDA cleared the pill for patients 12 and up with mild to moderate Covid who are most likely to end up hospitalized or not survive. The agency said it should be prescribed as soon as possible after diagnosis and within five days of symptom onset.
“Today’s authorization introduces the first treatment for COVID-19 that is in the form of a pill that is taken orally — a major step forward in the fight against this global pandemic,” Dr. Patrizia Cavazzoni, director of the FDA’s Center for Drug Evaluation and Research, said in a statement. “This authorization provides a new tool to combat COVID-19 at a crucial time in the pandemic as new variants emerge and promises to make antiviral treatment more accessible to patients who are at high risk for progression to severe COVID-19.”
The company reiterated Wednesday that it’s ready to start delivery in the U.S. immediately.
Pfizer’s pill is the first oral antiviral drugs authorized by the FDA that are specifically designed to fight Covid. The authorization comes at a crucial turning point in the pandemic, as hospital systems across the U.S. have been battered by a wave of delta infections, and are now bracing for another wave of patients infected with the highly contagious omicron variant.
The drug provides a new tool in the arsenal to fight Covid. While the vaccines have proven effective in preventing severe illness from the virus, health-care providers need medications to treat the tens of millions of people in the U.S. who still have not gotten vaccinated. The pill, if delivered in time, could help alleviate strain on health-care systems during an expected wave of omicron infections.
The U.S. has purchased 10 million courses of Pfizer’s treatment, Paxlovid, in a $5 billion deal. President Joe Biden said in November that his administration is working to ensure that the treatments are free and accessible. Biden said last month that delivery would start by the New Year and continue through 2022.
Merck has contracted with the U.S. government to supply at least 3 million courses of its pill, molnupiravir, which is still awaiting clearance, for $2.2 billion. The FDA declined to comment on Merck’s drug.
Pfizer’s treatment is administered in two 150 milligram tablets along with a 100 milligram tablet of an HIV drug, ritonavir, twice daily. The HIV drug helps slow the patient’s metabolism, which allows Paxlovid to remain active in the body at a higher concentration for a longer period.
Merck’s 800 milligram pill is taken every 12 hours for five days after symptom onset. The drug was developed with Ridgeback Biotherapeutics.
