Trial of Famotidine & N-Acetyl Cysteine for Outpatients With COVID-19

Phase 1
Terminated
Conditions
Covid19
Interventions
Registration Number
NCT04545008
Lead Sponsor
Prisma Health-Upstate
Brief Summary

The purpose of this trial is to assess the safety and toxicity profile of the combination of famotidine and oral n-acetyl cysteine in adult outpatients with newly diagnosed SARS-CoV-2 infection.

Detailed Description

This is a phase I trial enrolling subjects with newly diagnosed SARS-CoV-2 infection who do not require hospitalization. Exclusion criteria have been written to exclude patients who would be expected to have increased risk from either medication alone. Subjects will be assigned a dose combination of famotidine and n-acetyl cysteine. In addition to assessing the safety and toxicities profiles of the combination of drugs we will be measuring certain endpoints to assess possible efficacy. These endpoint include the following: rates of hospitalization; time to complete remission of symptoms, e.g, fever, respiratory symptoms, etc.; severity of symptoms with validated survey instruments; cytokine values in serum and urine; and markers of inflammation and oxidative stress.
