Health condition(s) or problem(s) studied:
Inflammatory response to surgery.

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Patients are randomised to receive oral Celecoxib through the perioperative period, or no anti-inflammatory prescription.
Specifically, patients in the Celecoxib group receive a loading dose of 400mg of oral Celecoxib capsules within 30 minutes prior to the induction of anaesthesia for surgery. Subsequently they receive 200mg of oral Celecoxib capsules at 12hourly intervals for a total of six dosing episodes (3 days).

A ‘half-dose’ regimen will be adopted (200mg loading dose followed by 100mg every 12 hours for a total of six dosing events) in the following scenarios at registration:
* Multiple cardiovascular risk factors: (any two of the following)
1. History of atherosclerotic disease;
2. Hypertension (treated with Angiotensin Converting Enzyme inhibitors, Angiotensin II receptor antagonists);
3. Cardiac failure (NYHA I).
* Age older than 65 years as well as body weight less than 50kg.
* Pre-operative Serum Creatinine of 100–149umol/L.

Monitoring:
Patients are seen daily on the wards by both treating clinicians and the study researchers following their surgery. Specifically, adverse events are enquired about, pain scores documented and standard post-operative blood tests acquired to monitor renal function. Pill compliance is documented. Patients are deemed compliant if they take at least 5/6 requested drug episodes.

Additional to the standard post-operative bloods are post-operative blood tests that are taken at baseline (induction), and then 6hrs, 24hrs and 48hrs hours following surgery. These tests are for research purposes to measure the effectiveness of Celecoxib in limiting the prostaglandin rise (inflammatory response to surgery). A baseline urine sample and 48 hour urine same is also collected.

Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Recruitment of patients for the study will usually occur at the Peter MacCallum Cancer Centre’s Pre-Anaesthesia Clinic (PAC). Typically, patients are seen in the PAC for an hour by an anaesthetist and anaesthetic nurse up to four weeks prior to surgery; four weeks will be an allowable time window prior to surgery. Patients have an electrocardiograph (ECG) performed and are asked to provide blood samples for routine preoperative testing. Following consultation, patients will be approached regarding participation in the study by an investigator who is independent of the patient’s treatment. This occasion will be used for the research nurse to discuss with the potential participant the aspects of participation in the study. The patient will be given the opportunity to ask questions and will be provided with a Participant Information and Consent Form. Informed consent will be achieved prior to signed and witnessed written consent. Patients who have consented for participation will be registered and given a de-identified study number.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
Allocation to the Celecoxib or control arms will occur on the day of surgery using the closed envelope method, where patients are randomised using serially numbered envelopes. The random allocation sequence will be computer generated using random block sizes by the study biostatistician who will then independently prepare the envelopes prior to the commencement of accrual. Envelopes will be securely stored by the study coordinator who would be contacted by the treating clinician to request access to a new patient’s treatment arm (on the day of surgery). The secrecy of the contents of the closed envelopes will be maintained using double envelopes.

Type of endpoint/s
Efficacy
Statistical methods / analysis
Analyses for the study will be per protocol based on compliance with 5/6 dosing events and meeting all of the inclusion and exclusion criteria. Baseline patient characteristics will be summarised for the whole sample and by treatment arm using descriptive statistics and will be reported for continuous variables as number of patients, mean, median, standard deviation, minimum and maximum; and for categorical variables as counts and percentages.

It is intended to report endpoints for all patients together, regardless of surgery type. It is hoped that there will be similar numbers of patients with each surgery type randomised to each arm, thus the randomised comparisons between arms of the endpoints will not be compromised by the addition of another type of surgery to the population of study.

For each of the primary endpoints the mean difference between the treatment arms will be calculated. Hypothesis testing will be performed for each endpoint at each time point separately using the appropriate statistical test based on the distribution of data. An independent two-sample t-test will be used if data are normally distributed or if an appropriate transformation can be found, otherwise a non-parametric Mann-Whitney U test will be performed. Given the exploratory nature of this pilot study, no adjustments for multiple comparisons will be made.

Pain scores at rest and movement will be summarised descriptively by treatment arm and mean differences between the treatment arms will be estimated.

To assess the safety of the Celecoxib dosing regimen, the incidence of post-operative adverse events, in particular, raised post-operative creatinine will be calculated separately for each treatment arm.
