Descriptive Information
Brief Title  ICMJE Safety and Preliminary Efficacy of the Combination of Niclosamide and Camostat
Official Title  ICMJE A Randomized, Single Blind, Placebo-controlled, Multiple Dose, Parallel-arm Study to Investigate the Safety and Preliminary Efficacy of the Combination of Niclosamide and Camostat to Treat COVID-19 ("NICCAM")
Brief Summary Niclosamide (2000 mg QD) and Camostate (600 mg QID) are expected to be safe and well-tolerated as a combination therapy and to show clinically beneficial for COVID-19 patients.
Detailed Description

Niclosamide is an approved drug for the treatment of intestinal worm infections that can potentially induce the process of autophagy and thus significantly limit viral replication in cells.

Camostat is approved in Japan for the treatment of chronic pancreatitis and reflux esophagitis. It has been shown to effectively block viral replication in a SARS-CoV-2 animal model.

Since the mechanisms of actions are different, it was hypothesized that a combination of both substances might have an additive or even synergistic effect in the treatment of patients with COVID-19.

This study is designed to investigate the safety, tolerability and preliminary efficacy of the treatment combination niclosamide and camostat in mild and moderately affected COVID-19 patients.
