Collaborative H1N1 Adjuvant Treatment Pilot Trial (CHAT)
Collaborative H1N1 Adjuvant Treatment (CHAT) Pilot Trial
調査の概要
詳細な説明
Primary Objective: The primary objective of the CHAT Pilot Trial is to assess our ability to recruit the desired patient population (i.e., the proportion of eligible patients enrolled in the trial), and to conduct a scientifically rigorous international RCT under pandemic circumstances.
Secondary Objectives: To evaluate (i) adherence to the medication administration regimen. (ii) the ability for research staff to collect the required primary and secondary endpoints for the planned full CHAT trial, (iii) the number of study withdrawals due to administration of open-label statins and withdrawals of consent and (iv) the impact of the approved consent model on recruitment rates.
Study Methods (Overview): Using a web-based randomization system patients, research coordinators will assign critically ill adults treated with antiviral medication for < or equal to 72 hours and requiring mechanical ventilation to one of two treatment strategies (rosuvastatin or placebo) for 14 days. Given the need to recruit patients into the CHAT Trial under pandemic conditions, when family members may not be present to provide written informed consent, we will request either a waiver of consent or deferred consent from Research Ethics Boards (REBs) at participating centres. The Keenan Research Centre/Li Ka Shing Knowledge Institute (St Michael's Hospital, Toronto, Ontario) will be the study Methods Centre.

実験的：Drug (Rosuvastatin) Crestor
The first dose of encapsulated study drug or placebo (day 1) will be administered within 4 hours of randomization as a loading dose of 40 mg.
The placebo will be identical in appearance to Rosuvastatin.
Thereafter, doses of 20 mg will be administered daily starting on the next calendar day at 10 pm daily (+/- 4 hours) as a maintenance dose from days 2 to 14.
If the patient is of Asian descent, is <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.
