Early High-Titre Convalescent Plasma in Clinically Vulnerable Individuals With Mild COVID-19

ABO compatible convalescent plasma infused intravenously on study day 1 (as soon as possible after randomisation) and the second on day 1 or day 2. Plasma obtained by apheresis from donors who have recovered from COVID-19 infection (at least 14 days after recovery) and have been vaccinated (at least 3 weeks after first dose of vaccine). A combination of both a SARS-CoV-infection and a SARS-CoV-2 vaccination of the donor is required - irrespective of the sequence of infection and vaccination. As far as the availability of CCP units allows, the two plasma units should have been donated by two different convalescents.

"Standard of care therapy may include anti-SARS-CoV-2 specific medication such as, but not limited to:~* Casirivimab~* Casirivimab / Imdevimab (REGN-COV2 or Ronapreve)~* Imdevimab~* Sotrovimab (Xevudy)~* Tixagevimab / Cilgavimab (Evusheld)~* Molnupiravir (MK-4482)~* Nirmatrevlir / Ritonavir (Paxlovid)~* Remdesivir~Centres should ensure that medications used as standard of care are used similarly for patients in both treatment arms."
