Merck's Covid Pill Hailed after Cutting Hospitalizations by 50%

US pharmaceutical company Merck said Friday it will seek authorization of its oral drug molnupiravir for Covid-19 after it was shown to reduce the chance newly infected patients were hospitalized by 50 percent.

A simple pill to treat the coronavirus has been sought since the start of the pandemic and Friday's announcement was hailed as a major step towards that goal.

"With these compelling results, we are optimistic that molnupiravir can become an important medicine as part of the global effort to fight the pandemic," said Robert Davis, the company's CEO and president, in a statement.

Anthony Fauci, chief medical advisor to President Joe Biden, told reporters "the data are impressive," and highlighted that the trial results showed there were no deaths among patients who received the drug compared to eight deaths in the placebo group.

The US has procured 1.7 million courses of molnupiravir should it be greenlighted, with the option to buy more, according to Jeff Zients, White House Covid coordinator.

Until now, Covid therapeutics such as monoclonal antibodies and Gilead's remdesivir have been administered intravenously, which holds back their widespread global use.

But experts also cautioned they would like to see the complete underlying data, and stressed that if eventually approved the drug should complement highly effective vaccines, rather than replace them.

Compelling results
In a late stage clinical trial, Merck and its partner Ridgeback Therapeutics evaluated data from around 770 patients -- roughly half of whom received either a five-day course of the pill, while the other received a placebo.

All the patients had lab-confirmed Covid-19 with symptoms that developed within five days of them being assigned to their respective groups.

Of the patients who received molnupiravir, 7.3 percent were hospitalized by day 29, compared to 14.1 percent of those on a placebo -- a relative risk reduction of around 50 percent.

Efficacy was said to hold up against variants of concern, including Delta, in the 40 percent of participants for whom sequencing data was available.

The drug had a good safety profile, with the frequency of adverse events approximately equal between the drug and placebo groups.

The results were compelling enough that an independent data monitoring committee in consultation with the FDA decided to halt the trial early, which could indicate they felt it would be unethical to continue with a placebo arm.

Merck said it plans to submit an application for an Emergency Use Authorization (EUA) to the FDA as soon as possible based on these findings and plans to submit marketing applications to other regulatory bodies worldwide.

Response from the medical community was favorable, with some notes of caution.

Eric Topol, director of the Scripps Research Translational Institute, wrote on Twitter the fact the results were so positive the trial was stopped "would be considered a Eureka moment in the fight against Covid."

But "this is no substitute for vaccination. It's not a miracle cure but a companion tool," tweeted Peter Hotez, dean of Texas Children's Hospital.

Experts also said it would be crucial to administer the drug early for it to be effective. Since it isn't always clear who is at risk for developing severe disease, it would have the greatest impact if it is cheap enough and safe enough to distribute widely.

Broad application
Molnupiravir belongs to a class of antiviral drugs called "polymerase inhibitors," which work by targeting an enzyme that viruses need to copy their genetic material, and introducing mutations that leave them unable to replicate.

"Viruses are basically little machines and they need certain components to replicate themselves," Daria Hazuda, Merck's chief scientific officer of the company's exploratory science center, told AFP in a recent interview. Antivirals disrupt the machinery.

Such drugs are expected to be more variant-proof than monoclonal antibody treatments, which target a surface protein of the virus that is continually evolving.

Molnupiravir was initially developed as an inhibitor of influenza and respiratory syncytial virus, two other important acute respiratory infections, by a team at Emory University.

"If it is proven to be very safe and proven to be effective, then it can be used broadly, irrespective of the diagnosis, to treat and prevent multiple respiratory infections," added Hazuda.

A Florida man was arrested and charged with two counts of attempted murder after shooting at a vehicle with two men who he thought were Palestinians but turned out to be Israeli visitors, local authorities and media reports said.

The website of Miami-Dade County Corrections says the suspect, 27-year-old Mordechai Brafman, was charged with two counts of attempted murder and booked on Sunday for the shooting on Saturday.

A police official confirmed earlier reports from local media that Brafman said in an interview with police that while he was driving his truck in Miami Beach, he saw two people he thought were Palestinian. He stopped, shot at and killed them.

However, the victims survived. One was shot in the shoulder and the other had a wounded forearm. They turned out to be Israeli visitors and not Palestinians, police said.

A representative or lawyer for Brafman could not be immediately identified by Reuters.

Human rights advocates say there has been a rise in anti-Muslim, anti-Palestinian and antisemitic hate in the United States since the start of US ally Israel's war in Gaza following an Oct. 7, 2023, attack by Palestinian group Hamas.
