Today marks the start of the phase 3 trial of Moderna's COVID-19 vaccine candidate. The COVE trial (Coronavirus Efficacy) will enroll 30,000 people at 89 sites across the country, with half the recipients receiving two shots of the vaccine 28 days apart, and the other half receiving placebos. The study is blinded.
According to Moderna, the primary endpoint will be the prevention of symptomatic COVID-19 disease, and secondary endpoints will include prevention of severe COVID-19 disease (as defined by the need for hospitalization) and prevention of infection by SARS-CoV-2, the virus that causes COVID-19, regardless of symptoms. The trial is being conducted in collaboration with the National Institute of Allergy and Infectious Diseases.
If Moderna's candidate is successful, it will mark the fastest vaccine development timeline in history. The Phase 1 study of mRNA-1273 was dosed on Mar 16, 63 days from the virus sequence selection.
Modern's mRNA vaccine is the first US vaccine to enter phase 3 trials, but at least three more are soon to follow: a vaccine made by Novavax, a candidate that's the product of a collaboration between the University of Oxford and AstraZeneca, and one by Johnson & Johnson. Each trial will require 30,000 healthy participants, and all are part of the U.S. government's Operation Warp Speed, which has set the goal of producing, manufacturing, and distributing an effective vaccine against the novel coronavirus by 2021.
Globally, there are currently 27 COVID-19 vaccines in human trials.
Yesterday, Moderna announced it would receive an additional $472 million from the Biomedical Advanced Research and Development Authority (BARDA) to fund the late-stage trial of its messenger RNA vaccine. Initially, Moderna received $483 million from BARDA to support the scale up of vaccine production and clinical development.
"We thank BARDA for this continued commitment to mRNA-1273, our vaccine candidate against COVID-19," said Stephane Bancel, Moderna's Chief Executive Officer, in a press release. "Encouraged by the Phase 1 data, we believe that our mRNA vaccine may aid in addressing the COVID-19 pandemic and preventing future outbreaks."

In Kentucky, Governor Andy Beshear is expected to announce today new restrictions to curb the outbreak in his state.
