About this study

Official title: A 3-Part, First-in-human, Double-Blind, Randomized, and Placebo-Controlled Study Assessing the Safety, Tolerability, and Efficacy of TO-O-1001 Ophthalmic Solution in Healthy Subjects and in Patients With Open-Angle Glaucoma or Ocular Hypertension

This is a Phase I/II stage to investigate the safety, tolerability, and ocular hypotensive efficacy of TO-O-1001 in healthy volunteers and patients with Open-Angle Glaucoma or Ocular Hypertension.

The proposed trial consists of 3 study parts to be conducted at Nucleus Network Melbourne.

This study will enroll up to 34 evaluable healthy volunteers in part 1(SAD) and part 2(MD) and 16 evaluable patients with Open-Angle Glaucoma or Ocular Hypertension in part 3(MD).

Note- As of 14Mar2023, enrolment has been completed for Part 1 and Part 2 and recruitment is pending now for Part 3.

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • TO-O-1001Drug

    TO-O-1001 ophthalmic solution in two concentration (0.05% and 0.1%) ocular administration only one drop in one eye

  • PlaceboOther

    The placebo is of same visual appearance and identical formulation as TO-O-1001, except the active component TO-168 ocular administration only one drop in one eye

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Safety and tolerability of TO-O-1001 though the incidence of adverse events.

    Number of participants with treatment-emergent adverse events (AEs).

    Measured: Up to 28 days

  2. Evaluate the ocular hypotensive efficacy of TO-O-1001 through Goldmann Applanation Tonometry.

    The primary efficacy outcome is mean IOP.

    Measured: Up to 28 days

Secondary outcomes (8)
  1. Pharmacokinetics of TO-O-1001. Blood samples obtained to evaluate the systemic exposure.

    Parameter: Area Under the Curve (AUC)

    Measured: Up to 8 days

  2. Pharmacokinetics of TO-O-1001. Blood samples obtained to evaluate the systemic exposure.

    Parameter: Maximum Concentration

    Measured: Up to 8 days

  3. Pharmacokinetics of TO-O-1001. Blood samples obtained to evaluate the systemic exposure.

    Parameter: Maximum observed concentration (Cmax in first and last dose)

    Measured: Up to 8 days

  4. Pharmacokinetics of TO-O-1001. Blood samples obtained to evaluate the systemic exposure.

    Parameter: Area under the concentration-time curve (AUC0-t and AUC0-inf in first and last dose)

    Measured: Up to 8 days

  5. Pharmacokinetics of TO-O-1001. Blood samples obtained to evaluate the systemic exposure.

    Parameter: Time of observed Cmax

    Measured: Up to 8 days

  6. Pharmacokinetics of TO-O-1001. Blood samples obtained to evaluate the systemic exposure.

    Parameter: Terminal elimination half-life and elimination constant in first and last dose

    Measured: Up to 8 days

  7. Best Corrected Visual Acuity (BCVA) of TO-O-1001.

    Visual function of the study eye was assessed using the ETDRS protocol. A higher score represents better functioning.

    Measured: Up to 28 days

  8. Safety and tolerability of TO-O-1001 through the incidence, severity and causality of serious adverse events (SAEs).

    Number of participants with treatment-emergent serious adverse events.

    Measured: Up to 28 days

Questions about this trial

What is this clinical trial studying?

A Phase 1/2 study testing TO-O-1001 in people with Open Angle Glaucoma and Ocular Hypertension, run by Theratocular Biotek Co. at 1 site in Australia.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 14 inclusion and 11 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: status not confirmed, as of the sponsor's last update on 19 Oct 2023. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in Australia. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this combined phase mean?

Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Results are not available in the source record.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Safety and tolerability of TO-O-1001 though the incidence of adverse events. (time frame: Up to 28 days). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 19 Oct 2023.
