Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Men or non-pregnant women, between 18 and 70 years on the day of inclusion.
  • Presence of one or more mild or moderate COVID-19 symptoms: Fever, cough, sore throat, malaise, fatigue, headache, muscle pain, gastrointestinal symptoms, or shortness of breath with exertion.
  • Positive test for SARS-CoV-2 in upper respiratory swab on the day of dosing (rapid antigen test).

Exclusion criteria

  • Requiring hospitalization at time of screening, or at time of study drug administration.
  • Oxygen saturation (SpO2) ≤ 93 percent (%) on room air at sea level, respiratory rate ≥ 30 per minute, or heart rate ≥125 per minute.
  • Any serious concomitant systemic disease, condition, or disorder that, in the opinion of the investigator, should preclude participation in this study.
  • Any co-morbidity requiring hospitalization or surgery within <7 days, or that is considered life-threatening within 29 days.
  • A patient reported history (prior to the current episode) of a positive SARS-CoV-2 serology test or a history of PCR confirmed SARS-CoV-2 infection.
  • Prior or concurrent use of SARS-CoV-2 antiviral medication, including convalescent serum or anti-viral antibodies.
  • Concurrent enrollment in any other type of medical research for improving COVID-19 outcomes or that is judged by the investigator not to be scientifically or medically compatible with this study.
  • Women that are currently breast feeding, pregnant, or plan to get pregnant during the duration of the trial.
  • Severe immunocompromised status (primary immunodeficiency, supraphysiological dose of systemic corticosteroids, transplant patients, known untreated HIV and CD4 T-cells <200/microliter) or use of any immunosuppressants that, in the opinion of the investigator, should preclude participation in this study.
  • Subjects at high risk for of COVID-19 related complications or mortality

Treatment and study plan

ensovibep

Drug

The study will start with a low-dose cohort and after a safety review escalate to the higher dose cohort. One administration at day 1 by infusion.

Other names: MP0420

Primary outcomes

  1. SARS-CoV-2 viral load

    Time frame: up to day 29

    Changes from baseline to each time point of measurement in SARS-CoV-2 viral load in nasopharyngeal swabs

  2. SARS-CoV-2 viral cultures

    Time frame: up to day 29

    Changes from baseline to each time point of measurement in SARS-CoV-2 viral cultures cultivated from nasopharyngeal swabs

  3. SARS-CoV-2 PCR days to negativity

    Time frame: up to day 29

    Duration in days to SARS-CoV-2 PCR negativity

  4. Observed maximum concentration (Cmax)

    Time frame: up to day 91

    The maximum observed concentration (Cmax) is estimated based on the serum concentrations.

  5. Terminal Elimination Half-Life (T½)

    Time frame: up to day 91

  6. Time to Cmax (Tmax)

    Time frame: up to day 91

  7. The area under the concentration-time curve from time zero extrapolated to infinity time (AUCinf)

    Time frame: up to day 91

  8. The area under the concentration-time curve from time zero to the time of the last quantifiable concentration (AUClast)

    Time frame: up to day 91

  9. Apparent total body clearance of the drug from plasma (CL)

    Time frame: up to day 91

  10. Apparent volume of distribution at steady state (Vss)

    Time frame: up to day 91

Secondary outcomes

  1. 14 Common Covid-19 Related Symptoms score

    Time frame: up to day 29

    Changes in the assessment of 14 Common Covid-19 Related Symptoms score

  2. Treatment-emergent (serious) adverse events ((S)AEs) and AEs of Special Interest (AESIs) including Infusion-related reactions (IRRs)

    Time frame: up to day 91

    Treatment-emergent (S)AEs and AESIs, including infusion-related reactions (IRRs) will be assessed throughout the study

  3. Concomitant medication

    Time frame: up to day 91

    Intake of concomitant medication will be assessed throughout the study

  4. Vital Signs: Heart Rate (bpm)

    Time frame: up to day 91

  5. Vital Signs: Blood Pressure Systolic and Diastolic (mmHg)

    Time frame: up to day 91

  6. Vital Signs: Respiratory Rate (breaths per minute)

    Time frame: up to day 91

  7. Vital Signs: Body Temperature (°C)

    Time frame: up to day 91

  8. Vital Signs: Oxygen Saturation (SpO2)

    Time frame: up to day 91

  9. Clinical laboratory tests (hematology and blood chemistry)

    Time frame: up to day 91

  10. Physical examinations (symptom directed)

    Time frame: up to day 91

  11. Local tolerability at injection site

    Time frame: up to 90 min post dose

    Local tolerability at injection site will be assessed via Visual Infusion Phlebitis score
