Health condition and Intervention

Section to complete information about the primary medical condition(s) or problem(s) studied and, a characteristics of the intervention(s).

Health condition(s) or Problem(s) studied:

COVID-19

Health condition(s) code:

Coronavirus Infections

SARS Virus

Coronaviridae Infections

Nidovirales Infections

Betacoronavirus

Severe Acute Respiratory Syndrome

Health condition keyword:

COVID-19

SARS-CoV-2

Intervention(s):

Itolizumab monoclonal antibody by intravenous route (IV). Administration must be very slow. The infusion should last at least 6 hours (approximately 25 drops / minute or less), following sterility and aseptic standards. It will use pre-infusion medication approximately 30 minutes (± 10 minutes) before the start of itolizumab administration. Each vial of itolizumab, produced in India, contains 100 mg of the monoclonal antibody in lyophilized form. The product must be reconstituted in 1.1mL of water for injection, leaving a concentration of 100 mg / mL of the monoclonal antibody. The calculated dose of itolizumab is diluted in 500 ml of saline, 0.9%. Pre-infusion medication: Hydrocortisone 100 mg IV or methylprednisolone 8 mg IV (or equivalent short-acting glucocorticoid) and diphenhydramine (or equivalent of an alternative antihistamine) 25 mg by intramuscular or intravenous route. Subjects already receiving systemic corticosteroid therapy (such as dexamethasone, methylprednisolone, or prednisone at a dose of ≥25 mg / day or equivalent) do not require glucocorticoid medication prior to infusion. If occurs an adverse event during the infusion, it is recommended decrease or close the drip until the event disappears. Then, the treatment will restart. Itolizumab does not contain preserve in the formulation, so it should be used immediately after preparing the infusion, discarding any unused remnants. Itolizumab diluted in 0.9% saline infusion is physically and chemically stable for 12 hours at temperatures below 25 degrees Celsius. If these limits are exceeded, the infusion must be discarded. If patient no improves the symptoms and signs of the systemic inflammatory disease, the patient may receive additional doses of itolizumab up to a maximum of 4 doses, with intervals of 3 to 7 days after the preceding dose.

Outcomes and Timepoint

Section to complete information about primary and secondary outcomes including. It includes the metric or method of measurement used and, the time point for every outcome.

Primary outcome(s):

Security outcomes: 1- Serious adverse events: From the total number of patients who will receive treatment, the percentage that developed serious adverse events will be calculated, according to the CTCAE v5.0 classification. Measurement time: Upon discharge of the patient. 2- Clinical and laboratory adverse events: The frequency distribution of AD appearance, type of event and body system will be determined. Duration, intensity, result, attitude and causal relationship of the AE will be identified. Measurement time: Upon discharge of the patient. Effect outcomes: 3- Rate of deceased patients in 14 days following the use of the drug. Measurement time: Upon discharge of the patient. 4- Rate of patients with disease progression (worsening in clinical status classification). Measurement time: Upon discharge of the patient.

Key secondary outcomes:

1- Proportion of Patients at Risk of Progression According to the CALL Index. Measurement time: Upon discharge of the patient. 2- Proportion of patients with high risk according to the MINSAP classification. Measurement time: Upon discharge of the patient. 3- Length of stay in intensive care. Measurement time: Upon discharge of the patient. 4- Hospital stay time. Measurement time: Upon discharge of the patient.

Selection criterias

Important: These cases will be treated in a different room with the supervision of the intensivists. Each case will be evaluated individually. (If the disease has been evolving for 8 days or more, treatment with Heberferon should be discontinued, and prophylactic anticoagulant treatment should be indicated in cases that meet the criteria for such therapy).
