- Brief Summary
The COVID-19 pandemic has led to an increase in the number of patients admitted to intensive care units (ICU) with acute respiratory distress syndrome (ARDS). ARDS is a severe, life-threatening medical condition characterised by inflammation and fluid in the lungs. There is no proven therapy to reduce fluid leak, also known as pulmonary oedema, in ARDS. However, recent studies have discovered that imatinib prevents fluid leak in the lungs in inflammatory conditions, while leaving the immune response intact.
Adding imatinib into the standard care package may, therefore, decrease mortality and reduce the duration of mechanical ventilation compared with standard care alone, in critically-ill patients with COVID-19.
To help determine the impact of imatinib in these patients we present a randomised, double-blind, multi-centre, 2-arm, parallel-group, placebo-controlled clinical study of intravenous imatinib in 84 mechanically-ventilated, adult subjects with COVID-19-related ARDS.
Study participants (patients who have consented into the study) will receive the study drug (imatinib or placebo) twice daily for a period of 10 days. The effect of the intervention will be tested by measuring the change from baseline in the Oxygen Saturation Index (OSI) at day 10. OSI is a non-invasive means of measuring oxygenation and is an independent predictor of mortality in patients with ARDS, serving thus as a relevant endpoint from which to assess the efficacy of imatinib.
Other measurements will include regular blood tests as part of safety assessments.
Time on ventilation and morbidity and mortality will be recorded as secondary outcome measures.
Blood tests will also allow the investigation of the pharmacokinetic properties of imatinib, as well as biomarkers of inflammation.

-
Provision of signed written informed consent from the patient or patient's legally acceptable representative
-
SARS-CoV-2 infection confirmed by RT-PCR laboratory test (which may include results from a test that was performed prior to hospital admission if, in the opinion of the Investigator, it is relevant to ongoing COVID-19)
-
Meet Berlin definition for moderate - severe ARDS
- Bilateral opacities - not fully explained by effusions, lobar/lung collapse, or nodules
- Respiratory failure not fully explained by cardiac failure or fluid overload.
- PaO2/FIO2 ≤200 mmHg with PEEP ≥5 cmH2O
-
Patient requires intubation or is currently intubated and has been for ≤48 hours
- Persistent septic shock (>24 hours) with a Mean Arterial Pressure (MAP) ≤65 mm Hg and serum lactate level >4 mmol/L (36 mg/dL) despite adequate volume resuscitation and vasopressor use (norepinephrine >0.2 μg/kg/min) for >6 hours
- Major trauma in the past 5 days
- Presence of any active malignancy (other than non-melanoma skin cancer) that required treatment within the last year
- Pre-existing severe cardiopulmonary disease including, but not limited to, interstitial lung disease; severe COPD (GOLD Stage IV or FEV1<30% predicted); heart failure (estimated left ventricular ejection fraction < 40%); or a chronic lung condition requiring home oxygen treatment
- An underlying clinical condition that, in the opinion of the Investigator, would make it very unlikely for the patient to be successfully weaned from ventilation due to severe underlying diseases (e.g., severe malnutrition, severe neurological disease)
- Patients considered inappropriate for critical care (e.g., being considered for palliative care)
- Currently receiving extracorporeal membrane oxygenation (ECMO)
- Severe chronic liver disease with Child-Pugh score >12 (Appendix 1)
- White blood count <2.5 x 109/L; Hemoglobin <4.0 mmol/L (6.5g/dL); Platelets <50 x 109/L
- ALT or AST >10x upper limit of normal (ULN) or bilirubin >3x ULN
- Women who are pregnant or breast-feeding
- Use of drugs with strong CYP3A4 induction potential, such as carbamazepine, efavirenz, enzalutamide, phenobarbital, phenytoin, hypericum, mitotane, nevirapine, primidone, rifabutin and rifampicin
- Inability of the ICU staff to initiate administration of study treatment within 48 hours of intubation
- Enrolled in a concomitant clinical trial of an investigational medicinal product
- In the opinion of the investigator, progression to death is highly probable, irrespective of the provision of treatments

- Primary Outcome Measures
Name Time Method Change from baseline in Oxygen Saturation Index (OSI) at Day 10 From Baseline to Day 10 Oxygen saturation is a calculation derived from \[mean airway pressure × FiO2 × 100\] / SpO2.
- Secondary Outcome Measures
Name Time Method Duration of mechanical ventilation (Days) to Day 29 and Day 60 To Day 29 and to Day 60 Number of days requiring to be on mechanical ventilation

Duration of stay in ICU (Days) to Day 29 and Day 60 To Day 29 and to Day 60 Number of days within the ICU
Change from baseline in WHO 9-point ordinal scale for clinical improvement to Day 10 and Day 29 The WHO ordinal scale will be recorded Days 1-10 and Day 29 The WHO Ordinal Scale for Clinical Improvement (0 to 8, where a higher value indicates worse outcome).
