Moderna said on Monday it has applied for U.S. emergency authorization for its COVID-19 vaccine after full results from a late-stage study showed it was 94.1% effective with no serious safety concerns, Reuters reported.
The U.S. Food and Drug Administration said an advisory committee would meet to discuss the request on Dec. 17, making Moderna’s candidate the second highly effective vaccine likely to receive U.S. regulatory backing and a potential roll out this year.
A shot developed by Pfizer Inc and BioNTech SE that was 95% effective in its pivotal trial is set to be reviewed by a panel of outside experts a week earlier. The FDA will decide on the emergency use authorizations (EUA) after the advisers make their recommendations.
Moderna, which also plans to seek European approval, reported that its vaccine’s efficacy was consistent across age, race, ethnicity and gender demographics as well as having 100% success in preventing severe cases of the disease that has killed nearly 1.5 million people worldwide.
“We believe that we have a vaccine that is very highly efficacious. We now have the data to prove it,” Moderna Chief Medical Officer Tal Zaks said. “We expect to be playing a major part in turning around this pandemic.”
Of the 196 people who contracted COVID-19 out of over 30,000 trial volunteers, 185 had received a placebo and 11 the vaccine. Moderna reported 30 severe cases, all in the placebo group.
Moderna shares rose 3% in extended trading after closing up 20%. They have gained about 700% this year.
“As the numbers of cases reported grows, confidence grows that this amazing protection will be maintained in a product that can be rolled out to protect the public,” said Alexander Edwards, associate professor in biomedical technology at Britain’s University of Reading.
In addition to filing its U.S. application, Moderna said it would seek conditional approval from the European Medicines Agency and continue to talk with other regulators doing similar rolling reviews.
“Although we await the full details of these results in published form, we can now assume that this vaccine will be approved for use in December,” said Gillies O’Bryan-Tear, chair of policy and communications at Britain’s Faculty of Pharmaceutical Medicine.
He expected Britain’s Medicines and Healthcare products Regulatory Agency to approve the vaccine within two weeks.
Moderna said it was on track to have about 20 million doses of its vaccine ready to ship in the United States by the end of 2020, enough to inoculate 10 million people.
Switzerland’s Lonza Group , which has a contract with Moderna to supply ingredients for the vaccine, rose 4.4%.
The vaccines developed by Moderna and Pfizer/BioNTech use a new technology called synthetic messenger RNA (mRNA) whereas others, such as AstraZeneca’s, employ more traditional methods.
AstraZeneca has announced an average efficacy rate of 70% for its vaccine, and as much as 90% for a subgroup of trial participants who got a half dose, followed by a full dose. Some scientists have expressed doubts about the robustness of the 90% efficacy figure for the smaller group.
