Study design
Purpose of the study
Treatment
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
At each centre, patients will be sequentially allocated a patient number.
All syringes will be prepared by the site clinical trial pharmacist according to the randomisation schedule, each syringe will be numbered according to the pre-determined randomisation code and labeled as ketamine/placebo 100, 300 or 500mg. All syringes will look identical in volume and colour to protect the blinding irrespective of the contents.
All new in-patients under the care or shared care of the palliative care team will be screened by the study nurse for their suitability to enter the study. The study nurse will ask the consultant in charge for permission to approach potentially eligible patients. This referral will be recorded within both the CRF and the patient clinical file.
Screening
If patients are suitable for entry and prepared to consent to the study, they will undergo baseline assessments and assessment of eligibility criteria and commence study the following morning. A screening log will be kept of all potentially eligible patients including the reasons for non entry.
At all times, from eligibility screening to completion of the study, all study staff are unaware of the treatment allocation. Allocation is concealed from the investigator at the time of the participant inclusion in the trial, the allocation is determined by contacting the site pharmacy.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Treatment for each patient will be allocated according to a block randomisation schedule held by the central registry in a 1:1 ratio. Block randomisation will ensure even allocation to each code. The central registry will supply strata tables to each site pharmacy.
Masking / blinding
