Swiss drugs regulator Swissmedic has said it approved Ronapreve, an antibody treatment jointly developed by Roche and Regeneron, to treat Covid-19 patients.

“In this procedure, no data on efficacy against the Omicron variant were submitted,” Swissmedic said in a statement.

The antibody treatment was already authorised for prescription in Switzerland under Covid-19 Ordinance 3 since April 15, Swissmedic said.
