Brief Summary

The purpose of this research study is to compare the effect of Netarsudil and Timolol on eye pressure and blood vessels of the back of the eye.

Conditions

OAG - Open-Angle Glaucoma; OHT - Ocular Hypertension

Outcome Measures

Primary Outcomes (1)

• Change in retinal blood vessel density

  The primary efficacy endpoint for this study is the change in retinal blood vessel density (peripapillary and macular) between treatment groups after 4 weeks of treatment (Visit 4 \[Week 5\] and Visit 6 \[Week 13\]).

  Through study completion, an average of 12 weeks

Secondary Outcomes (1)

• Change in best-corrected visual acuity

  Through study completion, an average of 12 weeks

Other Outcomes (1)

• Incidence of ocular and systemic adverse events

  Through study completion, an average of 12 weeks

Study Arms (2)

Netarsudil 0.02% QD

OTHER

4 weeks of Netarsudil 0.02% QD, then a 4 Week washout, followed by 4 weeks of Timolol maleate 0.5% BID

Other: Netarsudil 0.02% QD

Timolol maleate 0.5% BID

OTHER

4 weeks of Timolol maleate 0.5% BID, then a 4 Week washout, followed by 4 weeks of Netarsudil 0.02% QD

Other: Timolol maleate 0.5% BID

Interventions

Netarsudil 0.02% QD OTHER

This is a randomized, single-center, investigator-masked, 2-period, 8-week treatment study with washout and crossover between treatment periods. There will be 2 treatments in this study: netarsudil 0.02% QD and timolol maleate 0.5% BID.

Eligibility Criteria

• Age: 40 Years - 90 Years
• Sex: all
• Healthy Volunteers: Yes
• Age Groups: Adult (18-64), Older Adult (65+)

You may qualify if:

• Subjects must be between 40 to 90 years of age, inclusive, on the date the Informed Consent Form (ICF) is signed and with the capacity to provide voluntary informed consent
• Subjects must be able to read, understand, and provide written informed consent on the Institutional Review Board (IRB) approved ICF
• Subjects who are able and willing to comply with all treatment and follow-up/study procedures
• Female subjects who are not of childbearing potential or female subjects who have a negative urine pregnancy test result at Visit 1 (Screening) and Visit 3 (Randomization, Week 1)
• Females of childbearing potential, defined as a female who is fertile following menarche, must have a negative serum pregnancy test at screening and agree to use an acceptable method of contraception throughout their participation in the study. Note: Female subjects who have been surgically sterilized (e.g., hysterectomy or bilateral tubal ligation) or who are postmenopausal (defined as total cessation of menses for \> 1 year) will not be considered "female subjects of childbearing potential".

You may not qualify if:

• Subjects must have a diagnosis of OAG (including pigmentary or pseudoexfoliative) or OHT in 1 or both eyes. Subjects must not have ocular diseases to be included in the normal group.
• Subjects must have a diagnosis of OAG (including pigmentary or pseudoexfoliative) or OHT in 1 or both eyes. Subjects must not have ocular diseases to be included in the normal group.
• Subjects who are treatment-naïve must meet the following Intraocular Pressure (IOP) requirements at Visit 1 (Screening), and pretreated subjects must meet the following IOP requirements at Visit 2 (End of Washout):Intraocular pressure ≥ 20 mmHg in at least 1 eye and ≤ 30 mmHg in both eyes.
• Subjects participating in any drug or device clinical investigation within 30 days prior to Visit 1 (Screening) for subjects requiring a washout period, or 30 days prior to Visit 3 (Randomization, Week 1) for treatment naïve subjects.
• Subjects who anticipate participating in any other drug or device clinical investigation within the duration of this study.
• 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.
• Female subjects who are pregnant or breastfeeding.
• Subjects currently taking systemic B-adrenergic antagonists.
• Subjects with an anticipated need to initiate or modify medication (systemic or topical) that is known to affect IOP (eg, α-adrenergic agonists, calcium channel blockers, Angiotensin Converting Enzyme \[ACE\] inhibitors, and angiotensin II receptor blockers).
• Subjects with known hypersensitivity or contraindications to netarsudil or any of the ingredients in the study drugs.
• Subjects with known hypersensitivity or contraindications to timolol maleate or other adrenergic receptor antagonists 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 15 minutes following instillation of study drug and for 24 hours before check-in to and during each study visit.
• Subjects with a central corneal thickness greater than 600 um in either eye.
