Scientific title | A double-blind placebo-controlled randomised pilot trial of the utility of statins as an adjuvant anti-inflammatory treatment in critically ill adults with suspected, probable or confirmed H1N1 |
Study acronym | CHAT |
Study objectives | Data from both observational studies in humans and interventional studies in animals suggest that the course of influenza can be favourably influenced by agents that are not classically considered to be treatments for influenza. As many of these treatments are inexpensive and readily available, and because they may provide independent benefit in viral infection, they are attractive adjuvant treatments for patients around the world, and ideally suited to use during a global pandemic. Our focus will be on the potential utility of 3-hydroxy-3-methylglutaryl coenzyme A (HMG CoA) reductase inhibitors (statins) as an adjuvant anti-inflammatory treatment in critically ill adults with suspected, probable or confirmed H1N1 based on theoretical potential for benefit and promising experimental studies. |
Ethics approval(s) | 1. St Michael's Hospital Research Ethics Office approved on the 23rd December 2009 (ref: 09-314) 2. Comite d'ethique de la recherche de l'institut universitaire de cardiologie et de pneumologie de Quebec approved on the 2nd February 2010 (ref: HL-4610) 3. King Abdulaziz University Hospital Biomedical and Research Committee approved 30th January 2010 (ref: 340-10) All other centres will seek ethics approval before recruiting participants. |
Health condition(s) or problem(s) studied | Critically ill influenza A/H1N1 infection |
Intervention | Please note that as of 29/11/10 the anticpated end date of this study has been extended from 30/08/10 to 30/08/11. This trial is in the recruitment phase. Experimental drug: Rosuvastatin (Crestor®) - The first dose of encapsulated study drug (day 1) will be administered within 4 hours of randomisation as a loading dose of 40 mg. Thereafter, doses of 20 mg will be administered daily starting on the next calendar day at 10 pm (+/- 4 hours) as a maintenance dose from days 2 to 14. If the patient is of Asian descent, is aged less than 18 years, or serum creatinine is greater than or equal to 248 µmol/L (2.8 mg/dL) dose adjustments will be made according to a dose adjustment algorithm. Placebo Comparator - An identical appearing placebo will be administered to patients in the second study arm and administered once daily through an enteral feeding tube or administered orally if the patient is able to safely take oral medications. Total duration of treatment: 14 days (both arms) Total duration of follow-up: 90 days (both arms) |

Pharmaceutical study type(s) | |
Phase | Phase II |
Drug / device / biological / vaccine name(s) | Rosuvastatin (Crestor®) |
Primary outcome measure | Proportion of eligible patients enrolled in the CHAT Pilot Trial. Feasibility for the pilot study will be assessed by metrics that reflect our capacity to ultimately recruit a representative sample of 1050 patients in the planned full CHAT trial. We will consider the study to be feasible if we recruit at least 30% (commonly used threshold in ICU studies) of all eligible patients in participating ICUs through careful review of site screening logs. |
Secondary outcome measures | 1. Adherence to the medication administration regimen as outlined in the study protocol 2. Proportion of completed primary and secondary endpoints for the planned full CHAT trial that are collected 3. The number of patients who receive open-label statins 4. The number of consent withdrawals 5. Recruitment rates by approved consent model All outcomes will be measured upon termination of this pilot study. However, adherence to medication administration will be recorded daily on study days 1 through 14 for each study subject. |
