The objective of this parallel group study is to evaluate the safety, tolerability and efficacy of AMA0076 in reduction of intraocular pressure in subjects with primary open-angle glaucoma or ocular hypertension.

Inclusion Criteria:

• Adults 30-85 years of age.
• Diagnosis of either POAG or OHT in both eyes.
• Not receiving medication for IOP, or able to stop such medication for a washout period and the duration of the study without significant risk of adverse consequences related to glaucomatous disease.
• Elevated IOP (≥ 24 and ≤ 33 mm Hg at 8 AM and ≥ 21 and ≤ 33 mm Hg at 10 AM on Screening Two visit and Baseline visit in one or both eyes off treatment [after a washout phase in those subjects who were receiving ocular hypotensive therapy]).

Exclusion Criteria:

Ophthalmic exclusion criteria:

• Uncontrolled intraocular hypertension defined as > 33 mm Hg in either eye at either of the screening/baseline visits (after a washout phase in those subjects who were currently receiving ocular hypotensive therapy).
• Receiving more than one medication for IOP in either eye at time of screening.
• Abnormal central corneal thickness.
• BCVA worse than 20/200 (logMAR 1.0) in either eye
• Significant visual field loss.
• Acute angle-closure glaucoma or appositional or very narrow anterior chamber angle in either eye.
