We are experiencing 4 week turn-around time in review of submissions and resubmissions. We recommend commencing this process concurrently with your ethics submission and allowing at least 8 weeks for registration to be completed from date of first submission. We currently do not have the capacity to expedite reviews.

Note also there are delays to review of updates. We appreciate your patience.

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been endorsed by the ANZCTR. Before participating in a study, talk to your health care provider and refer to this information for consumers

Study type
Description of intervention(s) / exposure
Manuka Honey CycloPower is a near-white fine powder produced by combining (complexing) medical grade (MGO400+) Manuka Honey with alpha cyclodextrin, a naturally occurring sugar molecule. The complexing process uses liquid honey and produces a fine powder which is easily handled and suitable for inclusion into a number of final products and presentations. The product is presented in a hard shell capsule for oral administration.

There are two arms in four cohorts. In the first week one arm of each cohort will recieve a total of 400mg of the product, while all other arms will recieve the higher dosing stated above.
Eligible subjects will receive a total daily dose (either as a single dose or three (3) times a day) of Honey Cyclopower capsules at 400, 800, 1200, 2400, 3600, 4800mg total daily dose, or the matching placebo, taken with food. In each cohort 12 subjects will receive Honey Cyclopower while 4 will receive matching placebo in a completely blinded fashion.

The study will consist of a screening visit (Day -7 to -3), study period (Week 1-4) followed by a post treatment safety follow-up approximately 2 days after final dose. Once randomised, subjects will be given sufficient supplies for 7 days of treatment. At the end of each of the four weeks subjects will then return to the clinic where they will be assessed for safety and dosing compliance.
Intervention code [1] 286360 0
Comparator / control treatment
Placebo made up of maltodextrin, will be given at same dose as active treatment in the equivalent study arm
Control group

Primary outcome [1] 288678 0
To assess the presence of any gastro-irritant or other tolerability issues associated with consumption of Honey Cyclopower. Assessment is made by way of participants reporting any symptoms/effects they are experiencing and physical examination including blood pressure is completed prior to, at the midway point and following testing. It is therefore subjective reported data that will be used for assessment.

Secondary outcome [1] 300749 0
To assess for any biochemical changes to inflammatory markers, fasting blood glucose and oral flora

Procedure for enrolling a subject and allocating the treatment (allocation concealment procedures)
Subjects will be enrolled following signed informed consent. They will then be randomised using computer software and allocated a participant number. This number and the participant initials are the only identifying details on case record forms and will recorded by a party not involved with the research participants.

Brief summary
Honey Cyclopower is a near white free flowing powder produced by combining medical grade Manuka honey with alpha-cyclodextrin, a naturally occurring cyclical sugar molecule. Manuka honey is well known for its anti-bacterial and anti-inflammatory properties, and evidence exists to suggest it may have a role in lowering blood glucose levels. Alpha-cyclodextrin is a plant based sugar molecule that is sold in the USA as a weight loss support product due to its ability to bind to fat molecules and there is some research to suggest it lowers cholesterol, increases adiponectin and increases insulin sensitivity. While both products have GRAS status there is no researched or agreed limit on consumption of Manuka Cyclopower as it is an entirely new product. Two previous studies investigated the gastro-intestinal effect of Honey Cyclopower, the first using very high single doses and the second using much lower doses in a single day. There appears to be a gastro-irritant element to alpha-cyclodextrin when higher doses are consumed, but tolerable limits are not yet known. This research seeks to investigate two main parameters. The first is the potential effect of titration of the product on gastro-intestinal tolerability of the product and the second to provide an initial assessment of specified biochemical effects linked with the above health related claims.
