Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
In a randomised, cross-over design study to evaluate the bio-availability of Ursolic Acid.
Ursolic acid will be ingested orally on 3 separate occasions with a minimum 7day wash-out period in between doses. The study personnel will directly observe the participant ingesting the dose.
3 single doses of ursolic acid will be ingested;
1. 500mg,
2. 1000mg
3. 1500mg

Outcomes
Primary outcome [1] 307584 0
Determine the bio-availability of Ursolic Acid in the blood following oral ingestion.
This will be achieved by analysing the blood (plasma/serum) and urine UA concentration over the complete time-course after dosing. Typical non-compartmental pharmacokinetic analysis will be explored for the 3 different doses of UA from both blood and urine for concentrations of Ursolic Acid such as:
1. Maximum plasma concentration (C-max) [ Time Frame: 6 hours]
2. Time at C-max (T-max)
3. Elimination half life (T-1/2)
4. Elimination rate constant
5. Area Under the Concentration Time-Curve – The integral of the concentration-time curve, from time zero to infinity (AUC 0–8) and from time zero to the last measurable time point (AUC0–t)
6. Volume of distribution
7. Clearance rate
8. Metabolomic analysis will be conducted from urine samples to explore potential insights into UA induced changes in the metabolome
Timepoint [1] 307584 0
Blood will be sampled at 10, 20, 30, 45, 60, 75, 90, 120, 180, 240, 300 and 360mins post consumption for the determination of ursolic acid.
Secondary outcome [1] 352370 0
To determine the safety and tolerability of Ursolic Acid following oral ingestion. This will be achieved through:
1. The incidence of Treatment-Emergent Adverse Events (Time frame: 24hrs) collected through continuous observations of AEs during a dosing visit, monitoring vital signs and spontaneous reporting of AEs. AE’s will be summarized by frequency and severity.
2. The number of Serious Adverse Events
3. The number of Grade 3-4 biochemical abnormalities (criteria defined by the U.S. Department of Health and Human Services, National Institutes of Health, National Cancer Institute, Common Terminology Criteria for Adverse Events (CTCAE) Version 4.
Timepoint [1] 352370 0
AEs will be monitored continuously whilst under observation for 6hrs post ingestion and recorded for 24hrs post consumption.
Blood will be sampled 360mins + 24hrs post consumption for the determination of biochemical abnormalities.

Statistical methods / analysis
Ursolic Acid availability in humans has yet to be fully determined, thus a relevant power calculation is difficult to perform. Power calculations based on data from dose-response studies using different nutritional compounds are not applicable, as the bio-availability of each nutrient is inherently different to each other. However, we anticipate that with 8 participants (providing a total of 24 datasets), this will be adequate to achieve statistical significance in our results. It should be stressed that the primary aim of this study is to measure the appearance of Ursolic Acid in the blood following oral ingestion. As such, any increases in blood Ursolic Acid concentrations are likely to be significant, even with very low participant numbers. As we anticipate a 20% drop-out rate we will aim to recruit 10 healthy men. However, once 8 participants have completed all trials no further volunteers will be recruited. Data will be analysed via ANOVA.
