Covid-19 roundup: J&J plans 60,000-per­son PhI­II for Sep­tem­ber; Pe­ter Marks draws a red line

J&J is plan­ning the largest Phase III tri­al of a Covid-19 vac­cine to date, with a goal to en­roll 60,000 vol­un­teers to test its ade­n­ovirus-based shot.

The tri­al, whose de­sign was post­ed on clin­i­cal­tri­als.gov and sub­se­quent­ly con­firmed to End­points News, is ex­pect­ed to be­gin in late Sep­tem­ber. Al­though J&J is more than a month be­hind Mod­er­na and Pfiz­er/BioN­Tech, the fact that its tri­al in­volves a sin­gle-dose reg­i­men means it doesn’t have to wait 28 days be­tween two ad­min­is­tra­tions be­fore start­ing to record the ef­fects.
