The investigators are conducting a pilot trial where they will study safety, efficacy and compliance in a cohort of ambulatory patients in the Ghent region with confirmed COVID-19 infection, in both an early stage of disease, defined as less than 5 days of symptoms and who at presentation do not meet any criteria for hospitalisation as well as asymptomatic individuals with a PCR CT value below 30.

The primary endpoint is to assess the efficacy of the drug in terms of change from day 0 to day 5 in respiratory (oropharyngeal swab RT-PCR) log10 viral load.

The aim of the study is to assess whether Camostat, a serine protease inhibitor available in an oral formulation has the potential to be studied as an antiviral drug in a large scale ambulatory setting to prevent transmission by decreasing viral load, to prevent symptoms after exposure (PEP) in asymptomatic individuals or to prevent disease progression in the occurrence of early symptomatology.


Core study After eligibility assessment participants will be randomized and will receive the study drugs. We will define D1 as the first dose of the medication which can be the morning, midday or evening dose. They will be treated for 5 consecutive days.

In patients with a positive PCR at D5 (CT value with threshold below 30) and/or presence of clinical symptoms after exclusion of hospitalization criteria (flowchart emergency department appendix 4), the treatment will be extended up to D10 at the same dosage in both treatment arms for 5 consecutive days: D6 and D10).

Follow-up will be as follows:

  • D1->D14 (D28): The study participants will be asked to fill in daily questionnaires assessing symptoms (cfr daily self-score). They will receive a kit enabling to monitor heart rate (HR), respiratory rate (RR), temperature and oxygen saturation 3 times per day (every 4-8 hours, preferentially at the timing of medication intake at D1 to D5 or D10).
  • Compliance and tolerance will be assessed during the treatment period, D0->D5 (or D0->D10 if the treatment is prolonged).
  • During the study D1-D28: If indicated in the opinion of the investigator, a physical exam and biochemistry will be performed through a consultation at the clinic. This can be requested at any time during the study based on clinical symptoms or signs.
  • Consultation at D0, D5, (D10) and D28 at our COVID consultation facility. This will be done by a study nurse and/or a study physician.
