Please be advised that due to the high volume of submissions, the ANZCTR is currently experiencing delays in processing submissions from those outside of Australia and New Zealand. As the ANZCTR is funded by Australia and New Zealand, we must prioritise submissions from these countries first. International submissions should allow additional time for registration. Apologies for any inconvenience caused.

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

Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Part 1 - Single Ascending Dose (SAD)
There will be 7 cohorts of healthy volunteers dosed with single doses of oral EHP-101 liquid (7 planned dose levels from 0.91 to 200 mg), or placebo, and 1 potential additional cohort (also dosed with repeated or intermediate single dose of EHP-101, or placebo)
Participants will be confined to the Study Unit from Day -1 and discharged following collection of the 48 hour post dose assessments (Day 3). Total duration of participant involvement in Part 1 is 31 days from Day -1 admission to Day 30 End of Study assessments, with 4 days of clinic confinement.

Part 2 - Multiple Ascending Dose (MAD)
There will be 3 cohorts of healthy volunteers dosed with multiple doses (once or twice daily for a period of 7 days) of oral EHP-101 liquid (3 planned dose levels selected from doses investigated in Part 1), or placebo, and 1 potential additional cohort (also dosed with multiple doses of EHP-101, or placebo). Participants will be confined to the Study Unit from Day -1 and discharged on Day 9. Total duration of participant involvement in Part 2 is 31 days from Day -1 admission to Day 30 End of Study assessments, with 10 days of clinic confinement.
Each dose level investigated in the MAD part will not exceed the tested dose levels in the SAD part for which safety, tolerability, and PK data have been available and reviewed by the safety review committee.

Note for both Part 1 (SAD) and Part 2 (MAD):
Volunteers will be administered treatment under supervision by qualified staff in clinical confinement. Drug administration compliance and accountability will be checked by monitors during monitoring visits.

Outcomes
Primary outcome [1] 306797 0
To determine the safety and tolerability of oral EHP-101 when administered as a single ascending dose (SAD) to healthy subjects. This will be assessed by looking at the incidence, severity, causality and seriousness of adverse events; monitoring of vital signs; physical examination; ophthalmologic examination; cardiac telemetry; ECG; echocardiography; troponin levels; and any other clinical laboratory parameter abnormalities after a single oral dosing of EHP-101 liquid.
Timepoint [1] 306797 0
Adverse event information will be recorded from the time of informed consent until 30 days after last dose of study drug.
Primary outcome [2] 307015 0
To determine the safety and tolerability of oral EHP-101 when administered as a multiple ascending dose (MAD) to healthy subjects once or twice daily over 7 days. This will be assessed by looking at the incidence, severity, causality and seriousness of adverse events; monitoring of vital signs; physical examination; ophthalmologic examination; cardiac telemetry; ECG; echocardiography; troponin levels; and any other clinical laboratory parameter abnormalities after once or twice daily oral dosing of EHP-101 liquid over 7 days.
Timepoint [2] 307015 0
Adverse event information will be recorded from the time of informed consent until 30 days after last dose of study drug.
Secondary outcome [1] 349675 0
To determine the pharmacokinetic (PK) profile of EHP-101 liquid in healthy subjects following single and multiple oral doses. PK parameters determined are to include C(max), T(max). AUC, K(el), T(1/2), CL/F and Vz/F.
Timepoint [1] 349675 0
PK samples will be collected for plasma analysis during the treatment period at:
Pre-dose (less than or equal to 2 hours), 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, 24, 48, 72, 96, 120, 144, 168, 192 hours and 30 Days post-dose (Part 1, 21 time points) for single ascending dose.
Pre-dose (less than or equal to 2 hours), 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 14*, 15*, 16 (Days 1 and 7), 24, 48, 72, 96, 120 hours and 30 days post-dose (Part 2, 31 time points) for multiple ascending doses.
*in the event that doses are administered twice a day, samples at 14 and 15 hours post dose will also be collected.
Secondary outcome [2] 350362 0
To assess the PK effect(s) of a high-fat, high-calorie meal on the single-dose bioavailability of EHP-101 liquid in healthy subjects. PK parameters determined are to include C(max), T(max). AUC, K(el), t(1/2), CL/F and Vz/F.
Timepoint [2] 350362 0
PK samples will be collected for plasma analysis during the treatment period at:
Pre-dose (less than or equal to 2 hours), 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, 24, 48, and 72 hours (Period 1, 15 time points) for fasting condition.
Pre-dose (less than or equal to 2 hours), 0.5, 1, 1.5, 2, 2.5, 3, 4, 6, 9, 12, 16, 24, 48, 72, 96, 120, 144, 168, 192 hours and 30 days post-dose (Period 2, 21 time points) for fed condition.
Secondary outcome [3] 350705 0
To determine the pharmacodynamic (PD) profile of EHP-101 liquid in healthy subjects following single and multiple oral doses. Changes in the relative levels of proteins will be determined in selected cohorts. This screening will allow for selection of biomarkers for additional ELISA determination which may include erythropoietin, acidic fibroblast growth factor, leptin, platelet-derived growth factor-AA, coagulation factor III, pentraxin 3, vascular endothelial growth factor (VEGF), platelet-derived endothelial cell growth factor, vascular cell adhesion molecule-1, chemerin, chitinase 3-like, resistin, and endostatin in plasma before and after single and multiple dosing.
Timepoint [3] 350705 0
PD samples will be collected for serum analysis during the treatment period at:
Pre-dose (less than or equal to 2 hours), 6, 24, 48, and 72 hours post-dose (Part 1, 5 time points) for single ascending dose.
Pre-dose (less than or equal to 2 hours), 6, 24, 48 hours and 7 days post-dose (Part 2, 5 time points) for multiple ascending doses.
PD collection timepoints for Food Effect evaluation for both fasting and fed conditions are the same as those for Part 1, single ascending dose.
