Vir Biotechnology and Britain’s GSK said on Wednesday they planned to seek emergency use authorisation for their experimental Covid-19 antibody therapy after interim data from a study showed 85 per cent reduction in hospitalisation and deaths among patients.
An independent panel recommended stopping further enrolment for the late-stage trial due to evidence of “profound efficacy” of the therapy, Vir and GSK said in a joint statement.
Antibody treatments are designed to decrease the severity of Covid-19 among patients diagnosed with the infection.
Additionally, the companies said a new laboratory study showed the therapy, VIR-7831, was equally effective against the UK, South African and Brazilian variants of the coronavirus.
Vir and GSK announced a partnership last year to research Covid-19 treatments.
