Biomm S.A. announced that it is planning to submit an authorization request to the Brazilian National Health Surveillance Agency (“ANVISA”) in the next few days to conduct two Phase 3 clinical trials of leronlimab in Brazil for COVID-19. The two Phase 3 trials consist of trials for each severe and critically ill COVID-19 patients. Once approved by ANVISA, the Phase 3 trials will be conducted by Albert Einstein Israelite Hospital, an Academic Research Organization in Brazil. The COVID-19 trials in Brazil are intended to provide ANVISA with the requisite data to consider advancing the availability of leronlimab to thousands of Brazilians infected with COVID-19. These two Phase 3 trials will be conducted in up to 45 clinical sites. The critically ill protocol is for 306 patients while the severe protocol is for 594 patients, and interim analysis for both populations will be conducted when enrollment reaches about 40% of the total number for each trial.
