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.
