NCT07325240

Brief Summary

The purpose of this study is to evaluate the effect on 24-hour IOP reduction of netarsudil-latanoprost fixed combination in one eye compared to latanoprost alone in the contralateral eye, dosed daily, 1 drop at night (QD, PM) in adult subjects, at least 18 years of age, with open angle glaucoma (OAG) or ocular hypertension (OHT).

Outcome Measures

Primary Outcomes (3)

  • Change in mean Intraocular Pressure (IOP)

    Change in mean IOP from baseline at each time point for Latanoprost

    Change in mean IOP after 2 weeks of treatment with Latanoprost compared to baseline

  • Change in mean IOP

    Change in mean IOP from baseline at each time point for Rocklatan

    Change in mean IOP after 2 weeks of treatment with Rocklatan compared to baseline

  • Change in mean IOP

    Change in mean IOP from Latanoprost at each time point for Rocklatan

    Change in mean IOP from baseline after 2 weeks of treatment with latanoprost minus change in mean IOP from baseline after 2 weeks of treatment with Rocklatan

Secondary Outcomes (4)

  • Change in mean nocturnal IOP

    Mean nocturnal IOP will be calculated based on the time points during the sleeping hours (11 PM - 7 AM) after 2 weeks of treatment with Latanoprost compared to baseline

  • Change in mean nocturnal IOP

    Mean nocturnal IOP will be calculated based on the time points during the sleeping hours (11 PM - 7 AM) after 2 weeks of treatment with Rocklatan compared to baseline

  • Change in mean diurnal IOP

    Mean diurnal IOP will be calculated based on the time points during the sleeping hours (7 AM - 11 PM) after 2 weeks of treatment with Latanoprost compared to baseline

  • Change in mean diurnal IOP

    Mean diurnal IOP will be calculated based on the time points during the sleeping hours (7 AM - 11 PM) after 2 weeks of treatment with Rocklatan compared to baseline

Other Outcomes (3)

  • 24-hour IOP variability

    During the time period of analysis, approximately 18 months

  • Diurnal IOP variability

    During the time period of analysis, approximately 18 months

  • Nocturnal IOP variability

    During the time period of analysis, approximately 18 months

Study Arms (2)

Eligibility Criteria

Age18 Years+
Sexall
Healthy VolunteersNo
Age GroupsAdult (18-64), Older Adult (65+)

You may qualify if:

  • Diagnosis of OHT or mild-to-moderate OAG in both eyes (OAG in one eye and OHT in the fellow eye is acceptable) based on VF, OCT and dilated fundus examination within one year of the screening visit.
  • Both eyes must qualify for the study with an IOP of ≥18 mmHg but ≤34 mmHg on history or at the screening visit
  • Be able and willing to provide signed informed consent and follow study instructions
  • Ability to cooperate with the examinations required for the study and be able to attend all study visits
  • If a contact lens wearer, willing to remove contact lenses at least 24 hours prior to each of the study visits.
  • Best-corrected visual acuity (BCVA) using ETDRS chart of +0.4 logMAR units (Snellen equivalent \~ 20/50) or better in each eye

You may not qualify if:

  • Ocular:
  • Subjects with narrow angles (3 quadrants with Grade 2 or less according to Shaffer Scale), angle closure or a history of angle closure, or peripheral iridotomy in either eye
  • Severe glaucomatous damage
  • Difference in IOP between eyes \> 4 mmHg (unmedicated) at any baseline time point
  • Use of more than two ocular hypotensive medications within 30 days of screening
  • Chronic or recurrent inflammatory eye diseases in either eye
  • Ocular infection or ocular inflammation in the past 3 months in either eye
  • Ocular trauma other than corneal abrasion within the past 6 months in either eye
  • Clinically significant retinal disease (e.g., severe diabetic retinopathy, exudative or severe non-exudative macular degeneration, macular edema, retinal vein or artery occlusion) in either eye
  • Cornea pathologic changes preventing reliable measurement (e.g., scarring, opacity, edema, keratoconus) in either eye
  • Myopia greater than -6.00D, or hyperopia greater than +2.00D in either eye
  • Central corneal thickness less than 480 μm or greater than 620 μm in either eye
  • Previous intraocular surgery other than routine uncomplicated cataract surgery in either eye
  • Previous glaucoma intraocular surgery or glaucoma laser procedures (except SLT performed more than 6 months ago) in either eye
  • Unilateral intraocular surgery or glaucoma laser procedures
  • +11 more criteria
