Description of intervention(s) / exposure
Virofonol (the name for the pharmaceutical form of Polynol) capsules containing 250mg of the polyphenol rich sugar cane extract will be used for the study. The extract is Virofonol (the name for the pharmaceutical form of Polynol) capsules containing 250mg of the polyphenol rich sugar cane extract will be used for the study. The extract is a brown powder produced by spray drying the aqueous extract. There are no excipients in the capsule.
Virofonol contains a number of polyphenols and melanoidins. There is considerable literature on the antiviral and antibacterial properties of polyphenols.

Part A of this study will be performed in Australia. Part A of this study will investigate the pharmacokinetics of the main polyphenol constituents of Virofonol in healthy volunteers and assist in choosing the dose and frequency of administration of Virofonol.

Doses of 500mg, 750mg and 1000mg as a single dose will be administered orally in Part A of the study. Healthy volunteers aged between 18 and 55 years will be screened. Volunteers will be screened up to 28 days before enrolment.

Eligible patients will be identified by the investigator based on the physical examination, vital signs, laboratory parameters and Inclusion Criteria. On the day of admission (Day -1), volunteers will be admitted and have baseline tests performed to re-affirm their eligibility. The next day, on the morning of Day 1, the study dose will be administered and blood drawn at the required times (+/- 3 minutes). Volunteers will remain in the clinic overnight and then be discharged from the clinic on Day 2, after a blood draw collection 24 hours after the dose administration. A follow up phone call will be made 7 days (± 2days) after dosing to enquire about wellbeing and adverse events.

Each dose group will enrol a separate cohort of participants. Following completion of each cohort, all available safety data will be reviewed by the Safety Review Committee prior to commencing the next dose.

The 500mg dose group will be dosed first, then the 750mg group and then the 1000mg dose group sequentially following safety review by the Safety Review Committee (SRC).

Outcomes
Primary outcome [1] 330267 0
Establish the pharmacokinetic profile of Virofonol administered orally to healthy volunteers. The following PK parameters will be examined: Peak plasma concentration (Cmax) and Time to peak plasma concentration (Tmax) obtained from the plasma concentration data; Elimination half life (t1/2); Area under the concentration time curve from time 0 to the last point evaluated (AUC0-t); Area under the concentration time curve from time 0 and extrapolated to infinity; Volume of Distribution; Clearance.
Timepoint [1] 330267 0
Blood samples collected at pre-dose, 0.25, 0.5, 1, 2, 3, 4, 6, 9, 12 and 24 hours post-dose.
Primary outcome [2] 330269 0
Establish the safety of the selected doses following assessment of safety laboratory data, vital signs (including temperature, blood pressure, respiratory rate and heart rate), 12-Lead ECG, physical examinations and any treatment-emergent adverse events.

Temperature will be assessed using a tympanic thermometer.
Blood pressure will be assessed using a sphygmomanometer.
Respiratory rate (RR) will be assessed manually by observing subject at rest. RR will be determined by observing the rise of the subject chest, where one rise and one fall is equal to one respiration. The RR are taken for a 30 second period of time and the value doubled to calculate the subject breath per minutes.
Heart rate is measured using an automated vital signs machine
Timepoint [2] 330269 0
Treatment-emergent adverse events (TEAEs) will be collected from first day of dosing (Day 1) to Day 7 post-dose.
Vital signs, 12-lead ECGs, safety laboratory haematology and biochemistry will be collected at Screening (Day -28 to Day -2), Day 1 pre dose (and on Day 1 at 1hr, 2hr and 4hr post-dose for vital signs) and Day 2.

Eligibility
Key inclusion criteria
1. Age 18 to 55 years (inclusive at screening), BMI 18.0 to 32.0 kg/m2 who have given written informed consent.

2. Non-smoker or “light smokers” (less than or equal to 10 cigarettes or equivalent [e-cigarettes and marijuana] a week). Volunteers must agree to abstain from smoking whilst confine in the clinic

3. No clinically significant abnormalities (in the opinion of the Investigator) at the screening visit and prior to dosing.

4. Female volunteers of childbearing potential must have a negative serum pregnancy test at screening and negative urine pregnancy test at baseline.

5. Female volunteers must:
a. Be of nonchildbearing potential i.e., surgically sterilised (hysterectomy, bilateral salpingectomy, bilateral oophorectomy at least 6 weeks before screening) or postmenopausal (where postmenopausal is defined as no menses for 12 months without an alternative medical cause, and a follicle stimulating hormone level > 40 IU/L at the screening visit), or
b. If women of childbearing potential (WOCBP), they must agree to be on hormonal contraception for at least 1 month prior to screening, not to donate ova, not to attempt to become pregnant and, if not exclusively in same-sex relationships, if engaging in sexual intercourse with a non-sterile male partner, must agree to use a highly effective method of contraception and the male partner wear a condom, from signing the consent form until at least 30 days after the dose of the study drug.

6. Male volunteers must:
a. Agree to use a condom when engaging in sexual intercourse with a WOCBP, a woman of nonchildbearing potential (WNOCBP), or a male partner. In addition, the participant’s female partner if a WOCBP, she must use one of the listed forms of highly effective methods of contraception from signing the consent form until at least 90 days after the dose of study drug.
