Clinical Trial Summary

This master protocol serves as a common reference for the inpatient and outpatient clinical studies that share common elements.


Description:

There are currently two addenda to this master protocol: Addendum 1, Study LDOS-21-001-01, is a Phase 2, randomized, single-blind, placebo-controlled study to evaluate the safety and efficacy of the combination of famotidine and celecoxib as a treatment in moderate-to-severe patients hospitalized for COVID-19. Addendum 2, Study LDOS-21-001-02, is a Phase 2 randomized, placebo-controlled, double-blind study to evaluate the safety and efficacy of the combination of famotidine and celecoxib as a post-exposure prophylaxis (PEP) for newly infected COVID-19 patients.
