Safety and Efficacy of NP-120 (Ifenprodil) for the Treatment of Hospitalized Patient With Confirmed COVID-19 Disease

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.
