The purpose of this study was to evaluate the efficacy of ESBA105 over vehicle in reducing the ocular symptoms of dry eye disease, as measured by a mean global Visual Analog Scale (VAS) discomfort score.

Condition Intervention Phase
Eyes Dry Chronic
Biological: ESBA105 ophthalmic solution
Other: ESBA105 vehicle
Phase 2

Study Type: Interventional
Study Design: Allocation: Randomized
Intervention Model: Parallel Assignment
Masking: Double Blind (Subject, Investigator)
Primary Purpose: Treatment
Official Title: Evaluation of ESBA105 in the Persistent Relief of Ocular Discomfort in Patients With Severe Dry Eye

Further study details as provided by Alcon Research:

Primary Outcome Measures:
  • Visual Analog Scale (VAS) Global Ocular Discomfort Score, Area Under the Curve, Day 0 to Day 28 [ Time Frame: Up to 28 days ] [ Designated as safety issue: No ]
    An electronic Visual Analog Scale (eVAS) was used by the subject to assess ocular discomfort, both frequency and severity, at Day 0 (pre-treatment) and daily thereafter for 28 days. Assessments were entered into a LogPad® (handheld electronic device). The VAS frequency score ranged from 0 (rarely) to 100 (all the time), and the VAS severity score ranged from 0 (very mildly uncomfortable) to 100 (very severely uncomfortable). The Global Ocular Discomfort Score is a composite of the frequency and severity VAS scores (0-100).

Arms Assigned Interventions
Experimental: ESBA105
ESBA105 ophthalmic solution, 1 drop in each eye 3 times per day for 4 weeks
Biological: ESBA105 ophthalmic solution
Placebo Comparator: Vehicle
ESBA105 vehicle, 1 drop in each eye 3 times per day for 4 weeks
Other: ESBA105 vehicle
Inactive ingredients used as Run-In and placebo comparator

Detailed Description:

Following Run-In, patients qualifying for treatment were randomized 2:1 to receive ESBA105 (experimental group) or Vehicle (control group) for 4 weeks. Patients not qualifying for treatment (based on global VAS discomfort score), were discontinued from the study.
