Description of intervention(s) / exposure
This is a Single Dose (Fed and Fasted State) and Multiple Dose Phase trial. Subjects will be randomised to either orally receive with Cyclo-Z or placebo at doses and intervals presented below.

Active treatment will be an oral tablet of Cyclo-Z, a combination of Cyclo (His-pro) (CHP) at doses between 6mg and 60mg and zinc.

In the Singe Ascending Dose (SAD) Phase, there will be up to 5 cohorts with 8 subjects (6 active and 2 placebo). A total of 40 subjects are planned if all 5 dose levels are completed in the fasted state. The same 8 subjects (6 active, 2 placebo) from one dose cohort will be assessed for food effect after an approximately 7-day wash-out or 5 half-lives, whichever comes later.

Cohort 1 will receive 6mg CHP plus 23mg zinc, administered by oral tablet.
Cohort 2 will receive 15mg CHP plus 23 mg zinc, administered by oral tablet.
Cohort 3 will receive 30mg CHP plus 46 mg zinc, administered by oral tablets.
Cohort 4 will receive 45mg CHP plus 69 mg zinc, administered by oral tablets.
Cohort 5 will receive 60mg CHP plus 92 mg zinc, administered by oral tablets.

Dosing will take place in the morning on Day 1 under the supervision of the study staff. Subjects will each receive their first dose of study drug following a 12 hour fast. Water is allowed during the fast. Study drug compliance will be documented in the eCRF by recording: The date and time of the administration and the amount of tablets taken.

Participants will not be allowed to participate in both the SAD and MAD cohorts, however one cohort from the SAD Fasted cohorts will be selected to complete the SAD Fed cohort.

In the Multiple Ascending Dose (MAD) Phase, there will be up to 4 cohorts with 8 subjects (6 active and 2 placebo). A total of 32 subjects are planned if all 4 dose levels are completed.

Cohort 1 will receive 6mg CHP plus 23mg zinc by oral tablet once daily for 10 days.
Cohort 2 will receive 15mg CHP plus 23 mg zinc by oral tablet once daily for 10 days.
Cohort 3 will receive 30mg CHP plus 46 mg zinc by oral tablets once daily for 10 days.
Cohort 4 will receive 45mg CHP plus 69 mg zinc by oral tablets once daily for 10 days.

Dosing will take place in the morning on dosing days under the supervision of the study staff. Subjects will each receive their first dose of study drug following a 12 hour fast. Water is allowed during the fast. Study drug compliance will be documented in the eCRF by recording: The date and time of the administration and the amount of tablets taken.

Following the review of the SAD and MAD cohorts and dependent on the sponsor's review of trial data, the sponsor has allowed for the possibility to run an optional cohort(s). Should the sponsor and site proceed with the optional cohort(s), it will be assessing a Cyclo (his-pro) [CHP] only and/or a zonc only cohort with 8 subjects (6 active and 2 placebo). The dose for this optional cohort(s) will based on the emerging tolerability data from the MAD cohorts. New subjects will be recruited for this cohort.

The optional cohort(s) will follow the same schedule as the MAD cohorts, receiving daily oral tablet(s) dosing for 10 days. Dosing will take place in the morning on dosing days under the supervision of the study staff. Subjects will each receive their first dose of study drug following a 12 hour fast. Water is allowed during the fast. Study drug compliance will be documented in the eCRF by recording: The date and time of the administration and the amount of tablets taken.

An additional biocomparability cohort will be conducted as an open-label, two-way crossover evaluation to examine the PK and safety of two Cyclo-Z immediate release tablet formulations each containing 15mg CHP and 23mg zinc.

This cohort will consist of a 4-week screening period and two periods (Period 1 and 2) that are separated by an outpatient washout time of 7 (plus or minus 3) days. Subjects will be consented and screened for enrollment up to 4 weeks prior to Day -1 (check-in) and those subjects who meet all of the inclusion criteria and none of the exclusion criteria at Screening and Day -1 will be eligible to participate. During each of the two periods, subjects will remain at the clinical site for a 72 hour inpatient period.

Approximately 8 healthy subjects will be randomized on Day -1/1, in a 1:1 ratio, to receive 1 of 2 Cyclo-Z tablet formulations during Periods 1 and 2 (Tablet A/Tablet B or Tablet B/Tablet A).

Randomised controlled trial
Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Copies of the randomization sequence and treatment codes will be kept in the pharmacy at the Clinical Research Unit. Unblinded pharmacy (or other qualified site) personnel will be utilized to prepare the study drug for this trial.

Subjects will receive a 3-digit screening number at the Screening Visit, following informed consent and if deemed eligible, a randomization number will be allocated (based on the randomization schedule at any time from Day -1 to prior to Dosing on Day 1. The assignment of number and code for subject identification is based on the obligation for anonymity.
Methods used to generate the sequence in which subjects will be randomised (sequence generation)
This is a single center Phase 1 study; the study site's pharmacists (or qualified designee) will obtain the study drug assignment from a computer based randomization code list, by cohort, using a validated random generator software. The randomization scheme and codes will be generated by an unblinded statistician and provided to the site prior to study commencement.

Determination of Sample Size: The number of subjects for this study is not based on any formal sample size calculation. A total of 40 subjects for SAD and 32 subjects for MAD have been determined adequate to meet the study objectives, which are to establish the PK and safety profiles of escalating doses of Cyclo-Z doses administered as a single dose or multiple doses for 10 days.

Statistical Methods: The disposition, demographics, baseline characteristics, medical history, safety and PK variables will be summarized using descriptive statistics by treatment group and visit, as appropriate. For continuous variables, the descriptive statistics include: the number of observations (n), means, standard deviation (SD), median, minimum and maximum. For categorical variables, the summaries will contain the number and percentage of subjects falling into each category.

All demographic and baseline characteristics will be summarized by descriptive statistics utilizing the Safety, PK, and FAS analysis sets.

All pharmacokinetic variables will be summarized by descriptive statistics utilizing PAS.

All estimates for statistical modelling will be reported with SD and 95% confidence interval.

All analyses, summaries, and listings will be performed and will be generated using SAS software version 9.4 or higher.

Summary
Brief summary
Cyclo-Z treatment significantly improved insulin sensitivity in animal models of type 2 diabetes, further clinical trials of Cyclo-Z in diabetic subjects are warranted to determine if Cyclo-Z treatment results in clinical improvements.

Since the completion of the pilot Phase 1 clinical trial and the Phase 2 obese Type 2 diabetes trial, the formulation of Cyclo-Z was changed from a capsule to a tablet form. The current study is intended to obtain the additional safety data and pharmacokinetics of escalating doses of the revised formulation of Cyclo-Z when dosed once and when dosed daily for 10 days in healthy volunteers.
