Summary
Brief summary
The purpose of this adaptive trial is to determine the clinical efficacy of Ifenprodil in the
treatment of patients infected with COVID-19. This Protocol is largely based on the
recommendations of the World Health Organization (WHO) R&D Blueprint Clinical Trials Expert
Group COVID-19 Therapeutic Trial Synopsis, and associated Master Protocol.

The choice of the primary outcome measure will be determined by a pilot study of the first
150 subjects. Subject clinical status (on a 7-point ordinal scale) at day 15 in treatment
versus the control group is the default primary endpoint.
