A Study of PER-001 in Participants With Open-Angle Glaucoma

This clinical study has two phases: Phase 1 and Phase 2a. Phase 1 is an open-label, SAD study to investigate the ocular and systemic safety and tolerability of two dose levels of PER-001, in participants with advanced OAG. Phase 1 will enroll up to approximately 12 participants.

Phase 2a is a randomized, single-masked (participant) study to further investigate the ocular and systemic safety and tolerability of the two dose levels of PER-001 Intravitreal Implants in participants with progressing glaucoma. Participants who meet entry criteria will be randomized to receive either dose of PER-001 or sham control. In Phase 2a, a total of approximately 24 participants (12 in each Cohort, will be randomized).

Inclusion criteria

For Phase 1 and Phase 2a:

• Must be ≥ 18 years of age at the time of signing the informed consent

• IOP 6 to 25 mmHg (inclusive) at Screening in potentially eligible eye(s)

Phase 1:

• Best corrected visual acuity (BCVA) LogMAR score 1.0 or better at Screening in at least one eye and prior to randomization at Day 1 in the study eye
• Diagnosis of advanced or severe primary OAG including normal tension, pseudoexfoliation and pigment dispersion

Phase 2:

• BCVA LogMAR score 0.5 or better at Screening in at least one eye and prior to randomization at Day 1 in the study eye
• Primary OAG that is progressing in the study eye

Exclusion criteria

• Blood pressure >140/90 mmHg or <90/60 mmHg at Screening

• Any active uveitis and/or vitritis or history of idiopathic or autoimmune-associated uveitis
• Active infectious conjunctivitis, keratitis, scleritis, or endophthalmitis (Note: mild blepharitis is permitted if stable)
