LONDON - The world’s first COVID-19 human challenge trial is due to start in London next year, after the government announced £33.6 million (US$42.5 million) funding for the project. In the initial phase, the aim is to establish the dose of SARS-CoV-2 needed to cause infection and to characterize the immune response to virus. That will lead on to tests of individual COVID-19 vaccines, in which volunteers will be challenged with the effective dose of SARS-CoV-2 one month after inoculation.
CAJICA, Colombia – The Russian vaccine candidate Sputnik V, developed by Moscow’s Gamaleya National Research Institute of Epidemiology and Microbiology to prevent the SARS-CoV-2 virus that causes COVID-19, is undergoing phase III trials in Venezuela under complete secrecy.
DUBLIN – The Lancet Infectious Diseases has published the first clinical data on BBIBP-CorV, an inactivated whole virus vaccine directed against SARS-CoV-2. The early stage phase I/II study tested the Chinese-developed vaccine in 540 healthy volunteers, including 96 older participants. All vaccine recipients seroconverted and the adverse event profile was mild.
Johnson & Johnson said it has temporarily paused further dosing of its adenoviral vector-based COVID-19 vaccine candidate, JNJ-78436735, due to an unexplained illness in a study participant. Trial enrollment is also on hold while the company awaits a recommendation on how to proceed from the study's data safety monitoring board.
Astrazeneca plc said it has received about $486 million from the U.S. government to support the development and supply of a long-acting antibody combination under evaluation for the prevention and treatment of COVID-19. Phase III trials of the candidate, AZD-7442, are slated to begin later this month, the company told BioWorld. One trial will enroll more than 6,000 adults for the prevention of COVID-19 with additional trials set to enroll about 4,000 adults for the treatment of the infection, the Cambridge, U.K.-based company said.
LONDON – The first confirmed case of COVID-19 reinfection in the U.S. has been reported, with a patient testing positive for two distinct SARS-CoV-2 strains within 48 days, while testing negative in between contracting the two infections.
With COVID-19 cases once again surging across the globe and several countries considering targeted lockdowns, vaccines remain the best hope of restoring a sense of normalcy amidst the pandemic. For vaccines to work though, people must have enough confidence in the efficacy and safety that they’re willing to get vaccinated when the vaccines become available. That’s why the emergency use authorization (EUA) guidance the FDA released Oct. 6 for COVID-19 vaccines is so important.
With phase III vaccine trials nearly enrolled and data expected soon, a half-year of expedited development efforts, plus massive government funding may soon provide the ammunition needed to effectively stop the SARS-CoV-2 scourge of 2020.
Amid speculation that the White House had killed it, the FDA issued a promised guidance Oct. 6 on what it will take to get an emergency use authorization (EUA) for a COVID-19 vaccine.
HONG KONG – Cambridge, U.K.-based Astrazeneca plc has resumed phase I/II trials in Japan for AZD-1222, the experimental, adenovirus vector-based candidate coronavirus vaccine that it is co-developing with the University of Oxford.
