Primary Outcome Measures:
  • IOP [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    IOP measured in the study eye following 4 weeks of treatment


Secondary Outcome Measures:
  • Ocular Perfusion Pressure [ Time Frame: 4 weeks and 8 weeks ] [ Designated as safety issue: No ]
    Ocular Perfusion Pressure (OPP)(1/3 systolic blood pressure + 2/3 diastolic blood pressure) × 2/3 - IOP.

  • Area Under the Curve [ Time Frame: 4 weeks ] [ Designated as safety issue: No ]
    The Area Under the Curve(AUC) is the weighted average of IOP over the total IOP assessment time. The AUC will be calculated using the trapezoidal rule.

Criteria

Inclusion Criteria:

  • Subjects must have a diagnosis of OAG or OHT in 1 or both eyes.
  • Subjects who are treatment-naïve must meet the following IOP requirements at Visit 1 (Screening), and pretreated subjects must meet the following IOP requirements at Visit 2 (Washout): Intraocular pressure ≥ 22 mmHg in at least 1 eye and ≤ 36 mmHg in both eyes.

Exclusion Criteria:

  • Subjects who have been exposed to BOL-303259-X within 3 months prior to Visit 1 (Screening).
  • Subjects with a history or presence of chronic generalized systemic disease that the Investigator feels might increase the risk to the subject or confound the results of the study.
  • Subjects with an irregular daily sleep schedule.
  • Subjects who are unable to wear sleep monitoring device for 7 days prior to laboratory study.
  • Subjects with an anticipated need to initiate or modify medication (systemic or topical) that is known to affect IOP.
  • Subjects for whom concomitant use of medications may interact with the safety or efficacy of a nitric oxide.
  • Subjects with known hypersensitivity or contraindications to latanoprost or any of the ingredients in the study drugs.
  • Subjects who are expected to require treatment with ocular or systemic corticosteroids.
  • Subjects who are in need of any other topical or systemic treatment of OAG or OHT.
  • Subjects who are unable to discontinue contact lens use during and for 24 hours before the laboratory study.
  • Subjects with a central corneal thickness greater than 600 μm in either eye.
  • Subjects with any condition that prevents reliable applanationtonometry in either eye.
  • Subjects with advanced glaucoma and subjects with a cup/disc ratio greater than 0.8 or a history of split fixation, or a field loss threatening fixation in either eye.
  • Subjects with previous or active corneal disease.
  • Subjects with a history of severe dry eye.
  • Subjects with active optic disc hemorrhage.
  • Subjects with a history of central/branch retinal vein or artery occlusion.
  • Subjects with a history of macular edema.
  • Subjects with very narrow angles and subjects with angle closure, congenital, and secondary glaucoma, and subjects with history of angle closure in either eye.
  • Subjects with a diagnosis of a clinically significant or progressive retinal disease in either eye.
  • Subjects with any intraocular infection or inflammation within 3 months prior to Visit 1 (Screening).
  • Subjects with a history of ocular laser surgery within the 3 months prior to Visit 1 (Screening).
  • Subjects with a history of incisional ocular surgery or severe trauma within 3 months prior to Visit 1 (Screening).
