General information about the trial
|
|||
Main objective of the trial |
Will GM-CSF (a drug used to stimulate white blood cells) be able to restore the ingestion of germs by neutrophils (the most important white blood cells in fighting bacterial and fungal infection) to fight off infection in critically ill patients on intensive care?
|
||
Protection of trial subjects |
Participants were treated in routine critical care setting. All patients enrolled in the study received daily monitoring.
|
||
Background therapy |
Patients received background care in keeping with their critical illness. | ||
Evidence for comparator |
In controlled trials, the incidences of renal and hepatic dysfunction were comparable between Leukine and placebo treated patients. Patients who took part in the RCT component of the received either, an injection of the drug (GM-CSF) or an injection of a solution, with no effect (placebo or dummy drug). We then compared whether those patients who received the GM-CSF injection had an improvement in the function of their neutrophils compared to those who did not. | ||

Recruitment
|
||||||||||||||||||||||
Recruitment details |
The incapacitating nature of the condition precluded obtaining prospective informed consent from nearly all participants. Informed consent was sought from patients or a Personal or Professional Legal Representative. Due to the time dependent factors, a time limit of up to 24 hours to make a decision was given, but within 6 hrs if possible. | |||||||||||||||||||||
Pre-assignment
|
||||||||||||||||||||||
Screening details |
Daily screening of patients was performed on ICU (within 72hrs of admission). After consent, a blood sample was taken for assessment of neutrophil phagocytosis. If a patient’s phagocytosis index was >50% the patient was not recruited, ie not all patients consented were included in the dose-finding study or RCT. | |||||||||||||||||||||

Notes [1] - The number of subjects reported to have started the pre-assignment period are not the same as the worldwide number enrolled in the trial. It is expected that these numbers will be the same. Justification: The total number of patients screened in ICUs was 3634. Of these only 38 were randomised into the trial and therefore 3596 patients were ineligible at various points during the screening process. Consent was obtained for 64 patients, however 26 of these were were not eligible on the basis of phagocytosis screening following consent. |

Blinding implementation details |
Randomisation was a 1:1 ratio, with stratification by site, using a web-based randomisation service in NCTU. The randomised allocation schedule was generated by a statistician with no other involvement in the study to ensure independence and concealment of allocation. Permuted blocks of variable length were used to reduce the risk of breach of concealment of allocation. A treatment number was generated for each participant that links to the corresponding allocated study drug/placebo.

Dosage and administration details |
Each patient randomised to the GMCSF arm received up to 4 days of treatment with GM-CSF (sargramostim, Leukine®) as a subcutaneous injection. GM-CSF (Sargramostim, Leukine®, 250 microgram/vial) dosed on actual body weight (3mcg/kg) up to a maximum dose of 450mcg/volume 1.8ml. The dose/volume administered was prescribed according to the weight ranges given to give the dose to the nearest 5kg.

Notes [2] - The number of subjects at this milestone seems inconsistent with the number of subjects in the arm. It is expected that the number of subjects will be greater than, or equal to the number that completed, minus those who left. Justification: milestones relate to the number randomised, and those for whom primary endpoint data was collected at Day 2, and then further data collected at Day 9 and Day 30. Some data was not collected at Days 9, however data was collected at Day 30 for all participants. Primary endpoint data would be missing if, for example, a patient died before day 2.

Area under curve is calculated by summing the areas between each time point. This procedure is known as the linear trapezoidal rule.
In cases where there is missing data with no more data either before or after that point we do not calculate the area and treat that patient’s area under curve as missing.

Area under curve is calculated by summing the areas between each time point. This procedure is known as the linear trapezoidal rule.

The area under the curve up to day 4/5 is calculated for each patient. The summary statistics split by arm are then calculated.
