A patient-reported symptom tracking method used for patients with cancer has now been adapted for patients with COVID-19. Investigating the effect of famotidine, a potential treatment for COVID-19, on non-hospitalized patients with COVID-19, clinicians at Northwell Health and cancer researchers at Cold Spring Harbor Laboratory (CSHL) developed the method to use in addition to laboratory tests. This outpatient approach addresses the need to care for the majority of COVID-19 patients who do not require hospitalization. The first clinical case series showed that famotidine may help patients with mild to moderately severe symptoms from COVID-19. Next, the team will test the drug in a randomized clinical trial.
