Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Sentinel Participant 1 - PA5108 (16ug) - administered via intracameral injection, single injection to one eye
Sentinel Participant 2 - PA5108 (32ug) - administered via intracameral injection, single injection to one eye
Participants 3 to 7 - PA5108 (60ug) - administered via intracameral injection, single injection to one eye
Sentinel participant 2 will not be treated until after the 4 week safety assessment of Sentinel participant 1. Participants 3 to 7 will not be recruited until after the 4 week safety assessment of Sentinel participant 2.

All administrations of the ocular implant will be undertaken by a qualified and trained ophthalmologist.

All participants will continue to apply standard eye drop therapy to the non-treated eye to maintain intraocular pressure,

Outcomes
Primary outcome [1] 305528 0
To assess the safety and tolerability of PA5108 ocular implant in adults with Open Angle Glaucoma. Assessments are undertaken by a qualified ophthalmologist and include standard ophthalmic assessments for visual acuity, intraocular pressure, slit-lamp biomicroscopy and gonioscopy.
Timepoint [1] 305528 0
Patients are assessed until the ocular implant has completely biodegraded. It is anticipated that the implant will completely degrade no sooner than 20 weeks and no later than 12 months after the date of administration.
Secondary outcome [1] 345807 0
Assess by examination with slit-lamp biomicroscopy and gonioscopy for the presence of the Pa5108 ocular implant to determine the period required for complete biodegradation.
Timepoint [1] 345807 0
Assessed at 4 weeks, 3, 4.5, 6, 9 and 12 months until the implant has completely degraded

Summary
Brief summary
A single centre, open label, sequential dose study to assess the safety and tolerability of two strengths of PA5108 ocular implant in adult who have Open Angle Glaucoma. Participants who are currently administering combination drop therapy for Open Angle Glaucoma will be recruited. Drop therapy will cease in the treatment eye and continue in the contralateral eye. The treated eye will receive via injection, a single PA5108 ocular implant. Participants will be monitored for safety and tolerability of the ocular implant until it completely biodegrades.
