- Brief Summary
A Phase III, Multinational, Multicenter, Investigator-Masked, Randomized, Active-Controlled Trial, comparing the efficacy and safety of DE-130A with Xalatan® in Patients with Open-Angle Glaucoma or Ocular Hypertension over a 3-Month period, followed by a 12-Month Follow-Up with Open-Label DE-130A Treatment.
- Detailed Description
Phase III, prospective, interventional, multinational, multicentre, investigator-masked, randomized, active-controlled trial
Study duration:
* 5 days to 5-week washout period

Significant visual field loss (absolute defect in the 10° central point or mean deviation worse than -12 dB) or progressive field loss during the year before screening in either.
-
Significant optic nerve abnormality, other than glaucomatous abnormalities in the opinion of the investigator as determined by ophthalmoscopy in either eye.

-
Inability to visualize the patient's optic nerve in either eye.
-
Gonioscopy consistent with potential angle closure glaucoma in either eye.

Patients with severe blepharitis and/or Meibomian Gland Disease (MGD). Patients enrolled with mild to moderate blepharitis and/or MGD should be treated as appropriate during the study in either eye.
-
Use of oral or topical ophthalmic steroid within the past 14 days from screening date, or anticipated need for ocular steroid treatment during the study in either eye.
-
Use of intravitreal or peribulbar injection of depot steroid or placement of an intravitreal steroid implant within the past 3 months from screening date in either eye.

Known allergy or sensitivity to the study medications.
-
Active or expected ocular allergy during period 1.
-
Any active ocular disease (e.g. uveitis, ocular infection, severe dry eye with CFS grade 4 or more on the modified Oxford scale) in either eye. Patients may have mild cataracts, age-related maculopathy or background diabetic retinopathy if, in the opinion of the Investigator, it would not interfere with the conduct of the study.

-
Past history of any filtering surgery for glaucoma in either eye.

Group Intervention Description DE-130A DE-130A Instillation of one drop, once daily in the evening (9 pm ±1 hour) in the conjunctival sac of the affected eye(s). Both eyes will be treated unless the patient suffers from unilateral OAG/OHT Xalatan® Xalatan® Instillation of one drop, once daily in the evening (9 pm ± 1 hour) in the conjunctival sac of the affected eye(s). Both eyes will be treated unless the patient suffers from unilateral OAG/OHT DE-130A/DE-130A DE-130A/DE-130A After 12 weeks, continue to use DE-130A once daily for an additional 12 months. Xalatan®/DE-130A Xalatan®/DE-130A After 12 weeks, use DE-130A instead of Xalatan® once daily for an additional 12 months.
- Primary Outcome Measures
Name Time Method Intraocular Pressure (IOP) Change (mmHg) at Week 12 Week 12 (16:00) trough timepoint Intraocular Pressure (IOP) change from baseline trough (mmHg). IOP was measured using calibrated Goldman applanation tonometer in the afternoon (4:00 pm ± 1 hour). Analysis using Mixed-Effects Model for Repeated Measures (MMRM).
- Secondary Outcome Measures
Name Time Method Corneal Fluorescein Staining (CFS) Change From Baseline (First Key Secondary Endpoint) Week 12 CFS Change from baseline in participants with baseline CFS score ≥ 1 at Week 12
Staining using fluorescein were graded using the Modified Oxford scale (7-point ordinal scale, score 0, 0.5, and 1 to 5 per area for cornea and conjunctiva separately) as shown below:
* Score = 0: No staining dots
* Score = 0.5: One staining dot per area
* Score = 1: More staining dot per area than score 0.5
* Score = 2: More staining dot per area than score 1
* Score = 3: More staining dot per area than score 2
* Score = 4: More staining dot per area than score 3
* Score = 5: More staining dot per area than score 4
A Mixed-Effects Model for Repeated Measures (MMRM) was fitted to the CFS change from baseline at each visit.Ocular Surface Disease (OSD) Symptoms (Average of 3 Symptoms); Second Key Secondary Endpoint Week 12 Change from baseline in OSD symptom score (average of 3 symptoms: dry eye sensation, blurred/poor vision and burning/stinging/itching) in the study eye at Week 12 in patients with baseline symptom average score\>0.
Ocular symptoms were graded on a 5-point scale as shown below:
* Scale = 0: Absent
* Scale = 1: Mild
* Scale = 2: Moderate
* Scale = 3: Severe
* Scale = 4: Very severe
Least Square Means and p-values were obtained by fitting a Mixed-Effects Model for Repeated Measures (MMRM) model to the Ocular Surface Disease (OSD) average change from baseline at each visit.
