Official title

A Randomized Open Label Phase 2b/3 Study of the Safety and Efficacy of NP-120 (Ifenprodil) for the Treatment of Hospitalized Patient With Confirmed COVID-19 Disease

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

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.
