TOGETHER - Toronto: Trial to Evaluate the Effect of Peginterferon Lambda for the Treatment of COVID-19

Covid19 Clinical Trial

Official title: TOGETHER-Toronto: A Phase III Randomized, Double-blind, Placebo-controlled, Multicenter, Trial to Evaluate the Effect of Peginterferon Lambda for the Treatment of COVID-19

Status Active, not recruiting

Clinical Trial Summary

Interferon (IFN) lambda is one of the fundamental responses of the innate immune system. Peginterferon lambda is a long-acting form that has been studied extensively in human trials in viral hepatitis, confirming it safety and tolerability. It is particularly attractive for consideration in the use of acute respiratory illness due to the high expression of the lambda receptor in lung epithelia. We propose to evaluate peginterferon-lambda in ambulatory patients with mild to moderate COVID-19.

Clinical Trial Description

In this study, individuals who attend an Assessment Centre/Emergency Department to be swabbed for COVID-19 and deemed well enough for home isolation will be informed about the study. There will be two major routes of recruitment. Where feasible, a rapid point-of-care (POC) laminar flow based COVID-19 test (the Abbott PanBio) will be performed and those who do not have a POC test at the assessment centre will be tested by PCR. Interested participants who contact study staff will be confirmed to have a positive COVID-19 test. Once confirmed will be further screened for eligibility criteria by research study staff. After review, a consent form will be emailed to the participant and informed consent will be obtained through witnessed telephone consent from the participant or a substitute decision maker (SDM). Participants who consent will be randomized to receive a single subcutaneous injection of Peginterferon lambda 180µg or saline placebo. Patients will be followed remotely with visits. In addition, participants will also attend outpatient clinic for swabs and blood work for routine laboratory and inflammatory markers on Days 7 and 14 with the primary endpoint being the time to SARS-CoV-2 RNA negativity and the proportion with COVID-19 related emergency room assessment >6 hours, hospitalization or death by Day 28. Numerous secondary endpoints will be evaluated as well. Safety data will be reviewed by the Data Safety and Monitoring Committee after the first 50% of randomized participants complete 14 days of follow-up after treatment. ;
