Trial Review

Please note the ANZCTR will be unattended from Friday 20 December 2024 for the holidays. The Registry will re-open on Tuesday 7 January 2025. Submissions and updates will not be processed during that time.

Registering a new trial?

To achieve prospective registration, we recommend submitting your trial for registration at the same time as ethics submission.

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
Oral capsules of OCX063, to be taken in the morning on an empty stomach with water
- The first 6 participants will take 50 mg once daily for 28 days.
- The second 6 participants will take 100 mg once daily for 28 days
Depending on results from these 12 participants, an additional dose of either 25 mg or 75 mg may be studied. In that case 6 additional participants would take the selected dose once daily for 28 days.
Compliance will be monitored by review of a dosing diary and capsule count at each visit

Outcomes
Primary outcome [1] 335052 0
Pharmacokinetic (PK) profile of OCX063 including
• Peak plasma concentration (Cmax) of OCX063 obtained directly from the plasma concentration data without interpolation.
• Time to peak plasma concentration (tmax) of OCX063 obtained directly from the plasma concentration data without interpolation.
• Area under the concentration-time curve of OCX063 from time 0 to infinity (extrapolated) (AUC0-inf)
• Area Under the Plasma Concentration versus -Time Curve over a dosing interval (tau). Dosing interval is considered as actual time 24 hours (AUCtau)
• Accumulation ratio based on Cmax (RCmax)
• Accumulation ratio based on AUC (RAUC)
Timepoint [1] 335052 0
PK samples will be collected predose and at 1, 2, 3, 4, 6, 8, 12 and 24 hours post doses on Day 1 (first dose), Day 14, and Day 28
Secondary outcome [1] 422868 0
Safety of OCX063 as assessed by occurrence and incidence of treatment emergent adverse events (TEAEs)
Timepoint [1] 422868 0
From first dose of study drug on Day 1 to End of Study (EoS) on Day 35

There are no expected TEAEs at this stage of development. TEAEs will be recorded and assessed by asking participants if they have experienced any and by direct observation during study visits
Secondary outcome [2] 422869 0
Safety of OCX063 as assessed by physical examination including vital signs (blood pressure measured by machine or manual sphygmomanometer, heart rate and respiratory rate by manual count, and temperature by thermometer)
Timepoint [2] 422869 0
On Days 14, 28 and 35 of study compared to baseline (Day 1)
Secondary outcome [3] 422871 0
Safety of OCX063 as assessed by changes in blood tests including haematology, biochemistry, and coagulation
Timepoint [3] 422871 0
On Days 14, 28, and 35 of study compared to baseline (Day 1)

Eligibility
Key inclusion criteria

- Urinary albumin creatinine ratio greater than or equal to 30 mg/mmol, and/or urinary protein creatinine ratio greater than or equal to 50 milligrams per millimol
- If requiring treatment with an angiotensin-converting enzyme inhibitor (ACEi), angiotensin receptor blocker (ARB), or sodium-glucose cotransporter-2 (SGLT2) inhibitor, must be on a stable dose for at least the 4 weeks prior to Day 1, with the intent to remain on that dose during the study period.
