1 Platelet Inhibition With GP IIb/IIIa Inhibitor in Critically Ill Patients With Coronavirus Disease 2019 (COVID-19). A Compassionate Use Protocol

This is a compassionate use, proof of concept, phase IIb, prospective, interventional, pilot study in which the investigators will evaluate the effects of compassionate-use treatment with IV tirofiban 25 mcg/kg, associated with acetylsalicylic acid IV, clopidogrel PO and fondaparinux 2.5 mg s/c, in patients affected by severe respiratory failure in Covid-19 associated pneumonia who underwent treatment with continuous positive airway pressure (CPAP).

HPO:Pneumonia Thromboembolism

Primary Outcomes

Description: Change in ratio between partial pressure of oxygen in arterial blood, measured by means of arterial blood gas analysis, and inspired oxygen fraction at baseline and after study treatment

Measure: P/F ratio

Time: At baseline and 24, 48 and 168 hours after treatment initiation

Description: Change in partial pressure of oxygen in arterial blood, measured by means of arterial blood gas analysis, at baseline and after study treatment

Measure: PaO2 difference

Time: At baseline and 24, 48 and 168 hours after treatment initiation

Description: Change in alveolar-arterial gradient of oxygen at baseline and after study treatment. Arterial alveolar gradient will be calculated using the following parameters derived from arterial blood gas analysis: partial pressure of oxygen in arterial blood and partial pressure of carbon dioxide in arterial blood.

Measure: A-a O2 difference

Time: At baseline and 24, 48 and 168 hours after treatment initiation

Secondary Outcomes

Description: Number of days on continuous positive end expiratory pressure (CPAP)

Measure: CPAP duration

Time: From the first day of study drugs administration (T0) until day 7 post study drugs administration

Description: Difference in intensity of the respiratory support (non invasive mechanical ventilation, CPAP, high flow nasal cannula (HFNC), Venturi Mask, nasal cannula, from higher to lower intensity, respectively) employed at baseline and at 72 and 168 hours after study treatment initiation

Measure: In-hospital change in intensity of the respiratory support

Time: At baseline and 72 and 168 hours after treatment initiation

Description: Difference in partial pressure of carbon dioxide in arterial blood, measured by means of arterial blood gas analysis, at baseline and after study treatment

Measure: PaCO2 difference

Time: At baseline and 24, 48 and 168 hours after treatment initiation

Description: Difference in concentration of bicarbonate in arterial blood, measured by means of arterial blood gas analysis, at baseline and after study treatment

Measure: HCO3- difference

Time: At baseline and 24, 48 and 168 hours after treatment initiation

Description: Difference in concentration of lactate in arterial blood, measured by means of arterial blood gas analysis, at baseline and after study treatment

Measure: Lactate difference

Time: At baseline and 24, 48 and 168 hours after treatment initiation

Description: Difference in hemoglobin concentration in blood samples, measured by means of blood chemistry test, at baseline and after study treatment.

Measure: Hb difference

Time: At baseline and 24, 48 and 168 hours after treatment initiation

Description: Difference in platelet concentration in blood samples, measured by means of blood chemistry test, at baseline and after study treatment.

Measure: Plt difference

Time: At baseline and 24, 48 and 168 hours after treatment initiation

Description: Any major or minor adverse effect occuring during and after the administration of the study drug (e.g. bleeding)

Measure: Adverse effects

Time: From the first day of study drugs administration until day 30 post study drugs administration
