CAMOVID : Evaluation of Efficacy and Safety of Camostat Mesylate for the Treatment of SARS-CoV-2 Infection - COVID-19 in Ambulatory Adult Patients

A Multicenter Randomized Trial to Evaluate the Efficacy and Safety of Camostat Mesylate for the Treatment of SARS-CoV-2 Infection - COVID-19 in Ambulatory Adult Patients (CAMOVID)

The overall objective of the study is to determine the therapeutic effect and tolerance of Camostat mesylate, compared to placebo in adult patients with ambulatory COVID-19 disease, presenting with risk factors of severe COVID-19. Camostat mesylate is a serine protease TMPRSS2 (Transmembrane Serine Protease 2) inhibitor which has been successfully and safely used to treat pancreatitis-associated pain and post-operative reflux oesophagitis in Japan. More recently, it has been shown to inhibit SARS-CoV-2 viral entry and reduce infection of human primary pneumocytes and lung cell lines.

Camostat mesylate or placebo will be administered to consenting adult patients with virologically confirmed COVID-19, not requiring initial hospitalization. All patients will receive standard of care along with randomized treatments. Outcomes of included patients will be compared between the 2 groups.
