Study summary

An Open-label, prospective, randomized, comparative, multiple doses applied in addition to the standard of care treatment of patients with moderate to severe COVID-19 infection

Read the detailed description

The justification for the use of immunomodulatory therapy is based on the evidence that drugs that are inhibitors of interleukin IL6 may prevent the more severe lung tissue damage caused by cytokine release in patients with more severe COVID19. Several studies have suggested a "cytokine storm" caused by the release of IL-6, IL-1, IL-12 and IL-18 with tumor necrosis factor TNF alpha and other inflammatory mediators. Increased inflammatory response of lung tissue may result in increased gas exchange at the alveolar-capillary level making oxygenation difficult in patients with more severe forms of the disease and the need for mechanical ventilation. In this regard, it is hypothesized that the use of immunomodulatory therapy should have an effect in reducing the lethal outcome, the need for oxygen therapy, and mechanical ventilation.

Inclusion criteria

  • Patients with laboratory-confirmed (PCR) COVID-19 infection
  • Patients with moderate to severe COVID-19 infection
  • Hospitalized patients on clinical centers and cantonal hospitals
  • Patients with radiology-confirmed pneumonia within the clinical condition of COVID-19 infection including pulmonary opacity
  • Patients with a clinical indication for pneumonia: increased body temperature (defined as a value above ≥ 36.6⁰C axillary route, ≥ 37.2°C oral route or ≥ 37.8 °C rectal route), and/or dyspnea, and/or cough, and/or SpO2 \<96%
  • Patients aged above 18, both genders
  • Patients able and willing to understand the study, adhere to all study procedures and sign a written Form (ICF) prior to entering the study or with the assistance of the witness

Exclusion criteria

Exclusion Criteria:

  • Patients not COVID-19 positive
  • Patients with mild COVID-19 infection
  • Patients who are study subjects in another clinical study for another agent for COVID-19
  • Patients with malignant hypertension
  • Patients with malignant disease and who are treated for malignant diseases in the last 5 years
  • Patients with severe liver and kidney insufficiency
  • Patients who are receiving therapy with an immunomodulatory or agent
  • Patients aged below 18, female patients who are pregnant or breastfeeding
  • Known allergy to study drug or any component thereof
  • Use of haloperidol, dopamine antagonists, or nonsteroidal anti-inflammatory drugs, except paracetamol.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

What researchers measure

Primary outcomes

  1. Time to onset of change in the patient's clinical condition

    The time of onset of improvement in the patient's clinical condition will be measured following the clinical objective and subjective signs and radiological indicators.

    Time frame: 21 day

  2. Safety and tolerability evaluation - treatment-related adverse events will be assessed by CTCAE

    At every examination/evaluation, all AEs, whether noticed by investigators and their associates in the trial, or spontaneously reported by the subjects, or given as answer to direct question, must be evaluated by the investigator and reported on case report forms for AE. AE will be recorded in the e-CRF. Three-degree scale will be used for assessment of AE's severity: mild, moderate, severe.

    Time frame: 21 day

Secondary outcomes

  1. Length of in-hospital stay

    To monitor the period of patient's hospitalization

    Time frame: 21 day

  2. Survival rate

    To monitor the survival rate during the hospitalization

    Time frame: 21 day

  3. Intubation rate

    To monitor the intubation frequency during the hospitalization

    Time frame: 21 day

  4. Proinflammatory markers levels

    To monitor the levels of proinflammatory markers during the hospitalization (IL-6)

    Time frame: 21 day
