Covid-19 roundup: FDA com­mis­sion­ers call for more ‘con­cert­ed ef­fort’ on con­va­les­cent plas­ma R&D; Re­gen­eron boosts case for an­ti­body cock­tail with new an­i­mal da­ta

Four for­mer FDA com­mis­sion­ers have co­a­lesced around a cen­tu­ry-old treat­ment they be­lieve can give the best weapon against Covid-19: Con­va­les­cent plas­ma.

Writ­ing in The Wash­ing­ton Postfor­mer FDA com­mis­sion­ers Mark Mc­Clel­lan, Mar­garet Ham­burg, Robert Califf and Scott Got­tlieb said that while more work needs to be done to prove it’s safe and ef­fec­tive, con­va­les­cent plas­ma was a “promis­ing treat­ment” that “could help mil­lions of pa­tients with the nov­el coro­n­avirus both here and abroad.” They warned, though, that for it to be­come an ef­fec­tive tool in the US’ Covid-19 re­sponse, a more “con­cert­ed ef­fort” is need­ed to re­cruit donors and run tri­als.
