Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Simvastatin will be delivered in a new LipoCeramic formulation which contains soybean lecithin, Capmul MCM and silica nanoparticles. Two variations of silica nanoparticles will be trialled including Aerosil 300 and Syloid 224. These formulations will be referred to as LipoCeramic Formulation A and LipoCeramic Formulation B, respectively.

Volunteers will also be randomly assigned into Treatment Group 1 or Treatment Group 2 where they will be orally administered a simvastatin dose of 10 mg and 20 mg in LipoCeramic Formulation A or LipoCeramic Formulation B, respectively. Each dose will be administered with 240 mL of room temperature water following overnight fasting (at least 10 hours). Between each dose, there will be a 7 day wash-out period.

Prior to each dosing day, a reminder of the need to fast will be sent to the participant. During check-in on each dosing day, the participants will undergo a brief questionnaire to ensure they still adhere to the inclusion criteria and have not violated any exclusion criteria, including food intake.

All doses will be administered by a nurse and the oral cavity will be checked to ensure the capsule has been swallowed.
Intervention code [1] 312971 0
Treatment: Drugs
Comparator / control treatment
As a control, all subjects will receive one oral dose of a 20 mg commercial Simvastatin tablet (Sandoz Simvastatin). Simvastatin Sandoz, is manufactured by Sandoz Pty Ltd.

The dose will be administered by a nurse and the oral cavity will be checked to ensure the capsule has been swallowed.

Change in simvastatin plasma concentration
Timepoint [1] 308190 0
0.5, 0.75, 1, 1.5, 2, 3, 4, 6 and 8 hours post-dose administration
Primary outcome [2] 308191 0
Presence or absence of adverse events. The participants will be asked a non-leading question, such as, “how do you feel?"

Simvastatin is generally well-tolerated, however some patients may experience unwanted side effects with chronic use. The most common side effects of simvastatin which are mild and short-lived include: constipation, diarrhoea, wind, stomach upset or pain, nausea, headache and dizziness. If one of these were to occur, suitable medication will be administered to minimise discomfort for the patient. On rare occasions, patients have experienced the following side effects: aching muscles, muscle tenderness or weakness (not caused by exercise), brown/black coloured urine, tingling in the hand or feet, signs of anaemia (tiredness, shortness of breath, looking pale), fever, skin rash (hives), itchiness, painful or swollen joints, bruising more easily than normal and larger breasts than normal in men.

This will also be determined after a physical examination, including an electrocardiogram (ECG), revealing no abnormal findings, which in the opinion of the Principal Investigator, or medical nominee, would risk the safety of the subject of impact the validity of the study results.

4. Venous Access: Subjects require adequate venous access on their left or right arm to allow for collection of numerous blood samples.

5. Language: Fluent in English.

6. Informed Consent: Subject must voluntarily give written informed consent to participate in this study.

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)
Once a volunteer gives consent to participate in the screening process, they will be identified by a randomisation number between R001 and R014 inclusive. On acceptance to the study, recruited subjects will then be assigned and identified by a study specific identification number.

The randomisation number does not dictate which treatment the subject will recieve and thus can be given by the person conducting the screening process. However, the study specific identification number will dictate the treatment group and will be allocated by someone who is 'off-site'.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
To determine which treatment group the volunteers will be enrolled, a simple randomisation schedule will be generated using computer software.

Statistical methods / analysis
A total of 12 subjects will be included in the study. As this is a proof of concept study, no formal sample size justification has been performed.

The concentration of simvastatin in the plasma samples of all subjects will be determined via liquid chromatography–mass spectrometry using a validated analytical method. The plasma concentrations of simvastatin at all time points will be tabulated and summarised per treatment. Pharmacokinetic variables will be calculated for all subjects who consumed at least one dose of the investigational product. Summaries of pharmacokinetic parameters will also be produced for each treatment group.

Data sharing statement
Will individual participant data (IPD) for this trial be available (including data dictionaries)?
No
No/undecided IPD sharing reason/comment
A study report containing IPD will be produced, however this will not be publicly available.

A journal article may be published containing the results of the work performed in relation to the study. The plasma concentrations of simvastatin at all time points will be tabulated and summarised per treatment. The concentration-time profiles for each subject and the mean concentration-time profiles per each treatment will be plotted with linear and logarithmic axes for concentration. However, it is undecided how the results will be graphed for publication for public viewing.
