Brief Summary:
The Prevent-COVID study is a prospective, multicenter, randomized, two-armed, placebo-controlled, double-blind, interventional study in which the efficacy and safety of ivermectin in COVID-19 post-exposure prophylaxis (PEP) is examined in adult, close family contacts living in the household of a subject suffering from COVID-19.

Condition or disease Intervention/treatment Phase
Covid19 Drug: Ivermectin Drug: Placebo Phase 3

Detailed Description:

Study population and study sites:

The study is carried out in about 30 private practices or clinics in Germany that regularly carry out SARS-CoV-2 PCR tests and treat COVID-19 patients.

Adult close contact persons of newly diagnosed COVID-19 patients living in the same household are considered for participation.

Study duration and assessment:

The study will last 14 days, in which the following study-specific measures will be undertaken:

  • Documentation of demographics (age, gender, ethnicity, height and weight, degree of relationship to the COVID-19 patient)
  • Documentation of current comorbidities
  • Documentation of current medical accompanying measures
  • Documentation of the general condition
  • Vital signs
  • COVID-19 symptoms
  • SARS-CoV-2 PCR test: Only for medical confirmation of the presence of COVID-19 symptoms during an unplanned COVID-19 visit or final visit.
  • Subject diary (daily measurement of body temperature, contact intensity with the index person)
  • Pregnancy test in women of childbearing potential


Primary Objective: To demonstrate the efficacy of ivermectin in the COVID-19 post-exposure prophylaxis of adult contact persons living in the household of a person suffering from COVID-19 (index person)

Secondary objectives:

  • To demonstrate the safety of ivermectin in the COVID-19 post-exposure prophylaxis of adult contact persons living in the household of a person suffering from COVID-19 (index person)
  • To determine the severity of the symptoms of subjects suffering from COVID-19 during the study period and the comparison between the ivermectin and the placebo group.

IMP: Driponin® is an approved drug with the active ingredient Ivermectin, used to treat parasitic infections. One tablet Driponin® contains 3 mg Ivermectin. As part of the clinical trial, the medicinal product will be examined with regard to indication, dosage and application schedule deviating from the intended purpose and the package insert.

Drug Information available for: Ivermectin

Arm Intervention/treatment
Experimental: Ivermectin
2 doses of ivermectin at day 0 and day 2
Drug: Ivermectin

2 doses of Ivermectin will be administered with 48 hours time interval.

The dosage is based on body weight calculated as follows:

  • 15 mg for 40-60 kg = 5 tablets à 3 mg
  • 18 mg for 60-80 kg = 6 tablets à 3 mg
  • 24 mg for > 80 kg = 8 tablets à 3 mg each

This corresponds to an ivermectin dose of about 300 µg / kg.

Other Names:
  • Driponin
  • ATC-code P02CF01
  • Substance code SUB12089MIG

Placebo Comparator: Placebo
2 doses of placebo at day 0 and day 2
Drug: Placebo

An analogous number of tablets is administered for placebo:

  • 5 tablets for 40-60 kg
  • 6 tablets for 60-80 kg
  • 8 tablets for > 80 kg

The size, appearance, smell and taste of the tablets of placebo are identical to Ivermectin.

Primary Outcome Measures :
  1. COVID-19 disease [ Time Frame: Day 14 ]
    Occurrence of a COVID-19 disease up to the final visit (day 14), defined as the presence of the clinical condition according to the RKI case definition (acute respiratory symptoms of any severity OR new loss of smell and taste occurred OR illness-related death) AND a positive SARS-CoV-2 PCR test on the day the symptoms were determined (+/- 4 days)

Secondary Outcome Measures :
  1. Adverse events and side effects [ Time Frame: 14 days ]
    Number and severity of adverse events and side effects.

  2. Type, number and severity of symptoms [ Time Frame: 14 days ]
    Type, number and severity of symptoms within the 14-day of study on subjects suffering from COVID-19 (incl. hospitalization, oxygen saturation and demand, intensive care treatment)

  3. Severity of the COVID-19 disease [ Time Frame: 14 days ]
    Severity of the COVID-19 disease according to the investigator's assessment
