Pfizer, maker of the most widely-used COVID-19 vaccine in the U.S., is testing a potential pill-based treatment for the infection using the very same class of medication usually utilized to treat HIV.
Pfizer announced the start of a stage 1 clinical trial utilizing a protease inhibitor pill as a treatment for the infection on Tuesday. News of the trial comes months after Pfizer‘s COVID-19 vaccine, made in collaboration with the German firm BioNTech, was approved for usage and began to be administered in the U.S. and numerous other nations. The tablet, currently dubbed PF-07321332, could offer an additional weapon versus the infection as fast-moving mutations threaten to weaken the effectiveness of vaccines.
” Tackling the COVID-19 pandemic requires both prevention through vaccine and targeted treatment for those who contract the virus,” Pfizer’s Chief Scientific Officer Mikael Dolsten stated in a declaration acquired by Newsweek “Provided the manner in which SARS-CoV-2 is mutating and the continued worldwide effect of COVID-19, it appears likely that it will be critical to have access to therapeutic choices both now and beyond the pandemic.”
” We have actually developed PF-07321332 as a possible oral therapy that could be recommended at the very first indication of infection, without needing that patients are hospitalized or in important care,” included Dolsten.
The drug has actually revealed activity versus the infection that causes COVID-19 in test tube experiments, as well as activity versus other kinds of coronaviruses, with the business saying that the outcomes raise the possibility of “potential usage to deal with future coronavirus risks.”

Dolsten touted both the oral medication and the business’s previously-developed experimental protease inhibitor treatment designed to be administered to hospitalized COVID-19 clients intravenously, which is currently going through stage 1b trials. Dolsten stated that 2 different techniques use “the capacity to produce an end to end treatment paradigm that complements vaccination in cases where disease still happens.”
While none of the vaccines provide overall defense against contracting the infection, they have actually been revealed to substantially decrease infections and to be incredibly efficient in avoiding hospitalizations and death. Treatment choices might help reduce issues postured by the reality that a few of the anomalies presently making their way around the world have shown a restricted quantity of resistance to the vaccines, although both Pfizer and Moderna are establishing booster shots or new versions of vaccines to fight emerging variations.
As of Tuesday, over 64.6 million individuals in the U.S. had actually gotten at least one dosage of the Pfizer-BioNTech vaccine, according to the Centers for Disease Control and Avoidance.
Protease inhibitors, which block virus recreation by binding to proteins called protease, were a class of drugs that reinvented HIV treatment in the mid-1990 s. The drugs are likewise used against Hepatitis C infections, while researchers have actually examined their use as treatments for particular types of cancer and parasitic infections.
