Trial Review

Did you know?

The ANZCTR now automatically displays published trial results and simplifies the addition of trial documents such as unpublished protocols and statistical analysis plans.

These enhancements will offer a more comprehensive view of trials, regardless of whether their results are positive, negative, or inconclusive.

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

Can healthy volunteers participate?
Yes
Key exclusion criteria
For Healthy Subjects (Parts 1 & 2)

1. Subjects has chronic or acute ophthalmic disease including glaucoma, macular degeneration, and clinically significant cataract (primary or secondary).
2. Subjects has previous glaucoma intraocular surgery or glaucoma laser procedures within 3 years.
3. Subjects has refractive surgery (e.g., radial keratotomy, PRK, LASIK, etc.) within 5 years.
4. Subjects has ocular trauma within the past 6 months, or ocular surgery or laser treatment within the past three months (e.g., laser treatment for glaucoma or retina).

For Patients (Part 3)

1. Closed or very narrow angles (Grade 0-1) or those the investigator judges as occludable and/or with evidence of peripheral anterior synechiae (PAS) = 180 degrees by gonioscopy within 6 months prior to Screening Visit in either eye. (Patent laser iridotomy with Grade 1-2 angles is acceptable in either eye, providing the PAS criteria are still met).
2. Previous glaucoma intraocular surgery in either eye. Prior laser trabeculoplasty (ALT or SLT) in either eye is allowed if performed more than 6 months prior to Screening Visit.
3. Any non-glaucoma intraocular surgery within 3 months prior to Screening Visit in either eye.
4. Participation in a clinical study with use of any investigational drug or treatment within 28 days prior to Baseline (Day 1).
5. Clinically significant abnormalities in: laboratory tests, physical examination, vital signs and/or ECG at Screening Visit. If in the investigator's judgment a subjects with clinically significant abnormalities is appropriate for enrollment in the study, a discussion between the investigator and the Medical Monitor must occur and be documented prior to enrollment of this subjects in the study.

Summary
Brief summary
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.
