Pfizer seeks FDA authorization for its COVID-19 pill
WASHINGTON — Pfizer said Tuesday it is asking U.S. regulators to authorize its experimental pill for COVID-19, setting the stage for a likely launch of the promising therapy in the coming weeks.
The company’s filing comes as new infections are rising once again, propelled mainly by hot spots in states where colder weather is driving more Americans indoors.
It is one of a handful of pills that have recently been shown to significantly cut hospitalizations and deaths among people infected with COVID-19.
If authorized by the Food and Drug Administration, it could be a major step toward managing the pandemic and returning to normal, offering an easy, effective way for patients to treat themselves at home.
“We are moving as quickly as possible in our effort to get this potential treatment into the hands of patients, and we look forward to working with the U.S. FDA on its review of our application,” Albert Bourla, Pfizer’s chief executive, said in a statement.
All current FDA-authorized treatments for COVID-19 require an IV or injection given by a health professional at a hospital or clinic. FDA regulators will scrutinize company data on the safety and effectiveness of the drug, which would be sold as Paxlovid, before making a decision.
The FDA is holding a public meeting this month where outside experts will scrutinize a competing drug from Merck, before voting on whether to recommend approval.
The FDA isn’t required to convene such meetings and it’s not yet known whether Pfizer’s drug will undergo a similar public review.
Some experts predict various COVID-19 therapies eventually will be prescribed in combination to better protect against the worst effects of the virus.
Several smaller drugmakers are also expected to seek authorization for their own antiviral pills in coming months.
Pfizer reported this month that its pill cut hospitalizations and deaths by 89% among high-risk adults who had early symptoms of COVID-19. The company studied its pill in people who were unvaccinated and faced the worst risks from the virus because of age or health problems, such as obesity.
If the pill is authorized, the FDA will have to weigh making it available for vaccinated people dealing with “breakthrough” infections.
For best results, patients need to start taking the pills within three days of symptoms, underscoring the need for speedy testing and diagnosis. That could be a challenge if another COVID-19 surge leads to the testing delays and shortages seen last winter.
Pfizer’s drug is part of a decades-old family of antiviral drugs known as protease inhibitors, which revolutionized the treatment of HIV and hepatitis C. The drugs block a key enzyme that viruses need to multiply in the human body. That’s different than the Merck pill, which causes tiny mutations in the coronavirus until it can no longer reproduce itself.
On Tuesday, Pfizer signed a deal with a United Nations-backed group to allow generic drugmakers to produce low-cost versions of the drug for use in 95 countries.
