E.1.1 | Medical condition(s) being investigated |
|
E.1.1.1 | Medical condition in easily understood language |
Lung failure in critically ill patients |
|
E.1.1.2 | Therapeutic area | Diseases [C] - Respiratory Tract Diseases [C08] |
MedDRA Classification |
E.1.3 | Condition being studied is a rare disease | No |
E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The aim is to test the hypothesis that treatment with enteral simvastatin 80mg once daily for a maximum of 28 days will be of therapeutic value in patients with acute lung injury (ALI). The study has two distinct objectives:
Objective 1: To conduct a prospective randomised, double-blind, placebo controlled
phase II multi-centre trial of simvastatin for the treatment of ALI. |
|
E.2.2 | Secondary objectives of the trial |
To study the biological effect of simvastatin treatment on: (2a)
systemic markers of inflammation; (2b) systemic cell-specific indices of
activation and injury to the alveolar epithelium and endothelium; (2c) lung extracellular matrix degradation; (2d) assess whether response to simvastatin is determined by genetic polymorphisms as well as link genotypic information to the phenotypic information recorded as part of this study. |
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
1. Patient must be receiving invasive mechanical ventilation
2. Patient must have ALI as defined by acute onset of:
a) hypoxic respiratory failure (PaO2/FiO2 ≤ 40 kPa from 2 arterial blood gases >1 hour apart).
b) bilateral infiltrates on chest X-ray consistent with pulmonary oedema.
c) No clinical evidence of left atrial hypertension or if measured, a pulmonary arterial occlusion pressure (PAOP) less than or equal to 18 mmHg. If a patient has a PAOP > 18 mmHg, then the other criteria must persist for more than 12 hours after the PAOP has declined to < 18 mmHg, and still be within the 48-hour enrolment window
Acute onset is defined as follows: the duration of the hypoxia criterion (a) and the chest X-ray criterion (b) must be <28 days at the time of randomisation.
Infiltrates considered “consistent with pulmonary oedema” include any patchy or diffuse infiltrates not fully explained by mass, atelectasis, or effusion or opacities known to be chronic (>28 days). The findings of vascular redistribution, indistinct vessels, and indistinct cardiac borders are not considered “consistent with pulmonary oedema”.
All ALI criteria (a-c above) must occur within the same 24 hour period. The time of onset of ALI is when the last ALI criterion is met. Patients must be enrolled within 48 hours of ALI onset
|
|
E.4 | Principal exclusion criteria |
1. Age < 16 years
2. More than 48 hours from the onset of ALI
3. Patient is pregnant
4. CK >10 times the upper limit of the normal range*
5. Transaminases >8 times the upper limit of the normal range*
6. Patients currently receiving ongoing and sustained treatment with any of the following; itraconazole, ketoconazole, erythromycin, clarithromycin, HIV protease inhibitors, nefazodone, cyclosporine, amiodarone, verapamil or diltiazem. Patients receiving low dose erythromycin as a prokinetic will not be excluded
7. Patients with severe renal impairment (estimated creatinine clearance less than 30ml/minute) not receiving renal replacement therapy
8. Severe liver disease (Child's Pugh score >12; Appendix 1)
9. Current or recent treatment (within 2 weeks) with statins
10. Physician decision that a statin is required for proven indication
11. Contraindication to enteral drug administration, e.g. patients with mechanical bowel obstruction. Patients with high gastric aspirates due to an ileus are not excluded.
12. Domiciliary mechanical ventilation except for CPAP/BIPAP used for sleep-disordered breathing.
13. Known participation in other investigational medicinal product (IMP) trials within 30 days
14. Consent declined
15. Treatment withdrawal imminent within 24 hours
16. Non−english speaking patients or those who do not adequately
understand verbal or written information unless an interpreter is available.
*If CK, ALT and AST values are not available as part of routine care, a blood sample will be obtained after informed consent but before randomisation. CK, ALT, AST values may be obtained up to 72 hours prior to randomisation.
