Detailed Description

Since the appearence of the disease today known as COVID-19 there has been multiple interventions to try to gain knowledge on the subject and obtain a benefitial effect treating this condition.

Tocilizumab, a monoclonal antibody targeting IL-6 receptor has arised as an alternative for the treament of COVID-19 pneumonia.

It is a drug used for the treatment of rhemautoid arthritis and other autoimmune diseases as well as approved in recent years for the treatment of the cytokine release syndrome (CRS) in CAR-T therapy.

It is based in this last premise that the benefitial effect on COVID-19 pneumonia has been sought of. According to investigation into the physiopathology of the virus, it is supposed to trigger the inflamattory cascade that generates damage to lungs and creates the most severe cases of the disease. These findings could imply that tocilizumab may serve to interrupt this cytokine storm and prevent the progression of the disease.

The aim of the study is to evaluate the effectiveness and safety of tocilizumab in the treatment of severe cases of COVID-19. For that purpose, an observational retrospective cohort study has been designed comparing two populations that share the same indication for the treatment with tocilizumab. One having received the drug and the other in a close previous period of time that has not received it because of lack of availability or generalisation of its use. Mortality will be assesed as well as other variables such as need for mechanical ventilation and adverse effects of tocilizumab.

Study Population

Patients admitted to hospital with severe COVID-19 pneumonia that have progressed in the requirement of oxygen or need of non-rebreathing mask that have an active inflammatory state defined as persistent fever, CRP over 50 mg/dL or D dimer over 1000 ng/dL.

Description

Inclusion Criteria:

  • Hospital admitted patients with severe COVID-19 pneumonia (Individuals who have SpO2 <94% on room air at sea level, a ratio of arterial partial pressure of oxygen to fraction of inspired oxygen (PaO2/FiO2) <300 mm Hg, respiratory frequency >30 breaths/min, or lung infiltrates >50%).
  • Confirmed diagnosis of Covid-19 through qualitative polymerase-reverse transcriptase (qRT-PCR -GeneDX Co, Ltd o similar) or antigen rapid test.
  • Patients who received tocilizumab or shared the same indication but did not received it (same period of time or previous close period) that:

    • Progress in the requirement of supplemental oxygen (over 3L/m) and/or use of non-rebreathing mask with 8L/m or more to mantain a Sp02>= 94%.

AND

* Active inflammatory state defined as persistent fever > 38°C (defined as 2 or more measurements in a 24-hour period from hospital admission) despite the use of dexamethasone in the previous 48 hours OR C reactive Protein > 50 mg /dL OR D Dimer > 1000 ng/mL.

Exclusion Criteria:

  • Asymptomatic, mild or moderate COVID-19 disease.
  • Patients with some type of immunosupression (HIV, use of immunomodulatory drugs, organ-trasplant receipt patients)
  • Pregnant or breast-feeding
  • Patients with augmented risk of bowel perforation (history of diverticulitis or bowel surgery in the three months prior to the study entrance date)
  • Known severe allergic reactions to TCZ
  • Suspected active bacterial, fungal, viral, or other infection (besides COVID-19)
  • Alanine aminotransferase (ALT) or aspartate aminotransferase (AST) > 5 x upper limit of normal (ULN) at screening
  • Absolute neutrophil count (ANC) < 1000/mL at screening
  • Platelet count < 50,000/mL at screening
  • Positive Hepatitis B Surface (HbS) antigen
  • Procalcitonine > 0,5 ng/mL
  • Day of symptom onset before day 7 or after day 12
  • Patients with dementia
  • Patients non eligible to progress to mechanical ventilation because of frailty/comorbidites according to medical decision.

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Tocilizumab
Group that received tocilizumab (8mg/kg, maximum dose 800 mg, only once) while being admitted with severe COVID-19 pneumonia.
Tocilizumab received as a single intravenous infusion over the period of 60 minutes. Dose of 8 mg/kg, maximum dose of 800 mg.
Non-tocilizumab
Group that did not receive tocilizumab but share the same indication according to the elegibility criteria for it as the tocilizumab group while admitted with severe COVID-19 pneumonia.
