Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
The trial involves the sublingual administration of 5mg Rosuvastatin and placebo on a daily nocturnal basis in the subjects home. The trial drug is administered for 6 weeks with 2 week washout and another 6 weeks of matching placebo (or visa versa depending on randomisation schedule. Demonstration using sublingual placebo administration will occur at randomisation visit and subject compliance will be assessed at each visit by way of counting the number of tablets returned : number of days since randomisation. Fasting blood tests will also be taken prior to each visit to monitor safety + progress of cholesterol levels
Intervention code [1] 296142 0
Treatment: Drugs
Comparator / control treatment
The study is a cross over study - the subject will act as their own control
Subjects will be asked to take sublingual "5mg" placebo or sublingual 5mg crestor on a nightly basis at home for 6 weeks either in arm 1 or arm 2 and the repeat the process for another 6 weeks. Neither subject or investigator know which arm the patient is on active drug.
Control group
Placebo

Outcomes
Primary outcome [1] 299885 0
Change in Myalgia/muscle aches symptoms
Timepoint [1] 299885 0
Myalgia will be evaluated by subjects reporting adverse events at day 7 post drug administration. A myalgia score using analogue tool will occur at day 21 & 42 in 1st arm post administration and day 84 & 105 post administration in 2nd arm.
Elevated muscle enzymes (CK) will be measured at days 7, 21 &42 post drug administration in 1st arm and day 84 & 105 post drug administration in 2nd arm.
As we are blinded, 1st arm may be rosuvastatin or placebo + 2nd arm may be rosuvastatin or placebo.
Primary outcome [2] 300096 0
change in total blood cholesterol
Timepoint [2] 300096 0
assessed by fasting blood test at 7, 21 and, 42 days post sublingual drug administration in 1st arm and days 84 & 105 post sublingual drug administration in 2nd arm.
As we are blinded, 1st arm may be rosuvastatin or placebo + 2nd arm may be rosuvastatin or placebo.
Secondary outcome [1] 328397 0
stable memory
Timepoint [1] 328397 0
assessed using Montreal cognitive assessment tool at day 42 post sublingual drug administration in 1st arm and day 105 post sublingual drug administration in 2nd arm
As we are blinded, 1st arm may be rosuvastatin or placebo + 2nd arm may be rosuvastatin or placebo.

Study design
Purpose of the study
Prevention
Allocation to intervention
Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Allocation was concealed as to when subject would be on the active or placebo drug - either the 1st arm or 2nd arm.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
A letter A or B was drawn from a container to allocate which container they would start on and it would change to the other letter for the 2nd 6 weeks. A is either active drug or placebo or B is active drug or placebo.
Masking / blinding
Blinded (masking used)
Who is / are masked / blinded?
The people receiving the treatment/s
The people administering the treatment/s
The people assessing the outcomes
The people analysing the results/data

Statistical methods / analysis
In order to detect an effect size of 1.4mmol / L between treated and non-treated subjects for total cholesterol with a standard deviation of 1.41 at an alpha level of 0.025 and beta =0.95, we need 16 subjects. Assuming a dropout/noncompliance rate of 20% we inflate the sample size to 20. We used Stata v.14 to compute the required sample size for a simple crossover trial that is AB/BA. This method is similar to a one-sample t-test for the difference between treatment regimes, except that this calculation uses the non-central t-distribution. Data will be analysed as two-sample t-test comparing changes within and between rosuvastatin treatment and no treatment allocations after ensuring there was no carry over, sequence or period effect. Paired two-sample t-test will be used for within
allocation comparisons whereas unpaired two-sample t-test will be used for between treatment allocation comparisons. Continuous variables will be expressed as mean ± SD, categorical variables as frequency and percentage. A p-value of = 0.05 will be considered statistically significant. All analyses will be performed in Stata 14.
