A Study to Assess the Safety and Efficacy of ECF843 vs Vehicle in Subjects With Dry Eye Disease

The study was planned to be conducted in 2 parts: Part 1 to determine the efficacy and safety of ECF843 vs vehicle, followed by Part 2 with additional exploratory assessments of ECF843 vs Vehicle. Both parts of the study included a double-masked study design, with randomization stratified for subjects with Sjogren's Syndrome.

About this study

Part 1 of the study was a double-masked, randomized, parallel design in which participants were assigned to one of the following five treatment arms/groups in a ratio of 1:1:1:1:1.

  • ECF843 0.45 mg/mL three times daily (TID) or vehicle
  • ECF843 0.15 mg/mL TID or vehicle
  • ECF843 vehicle TID
  • ECF843 0.15 mg/mL twice daily (BID) or vehicle
  • ECF843 vehicle BID The planned duration of double-masked treatment during Part 1 was 56 days. For subjects randomized to ECF843, the maximum drug exposure was up to 28 days. At some point during Part 1, all participants received vehicle.

The study was terminated after completion of Part 1 and Part 2 of the study was not therefore initiated.

Primary outcomes

  1. Part 1: Change From Baseline in Symptom Assessment in Dry Eye (SANDE) Score

    Time frame: Up to 28 days (Baseline (BL) to end of randomized treatment)

    The SANDE uses a 100 mm visual analog scale (VAS) and asks the subject to score frequency and severity of their ocular discomfort over the past 24 hours by putting a vertical mark on two separate horizontal scoring lines. The frequency scoring line utilizes the anchors of 'Rarely' to 'All the Time', while the severity scoring line utilizes the anchors of 'Very Mildly' to 'Very Severely uncomfortable'. The SANDE questionnaire was completed through an electronic diary by the subject at the Screening Visit(s) of Part 1, and thereafter every evening before bedtime during the study. The overall SANDE score was calculated by taking the square root of the product of the frequency of symptoms score and the severity of symptoms score. The SANDE scale ranged from 0 to 100 with 100 being the maximal amount of dry eye symptoms and 0 being the minimal amount of dry eye symptoms. Negative change from baseline indicates improvement.

  2. Part 1: Change From Baseline in Composite Corneal Fluorescein Staining Score

    Time frame: Up to 28 days (Baseline (BL) to end of randomized treatment)

    The degree of staining was based on the Corneal Fluorescein Modified NEI Scale. Each of the five regions (central (C), superior (S), inferior (I), temporal (T), and nasal (N)) were graded based on a scale of 0 to 4, with higher scores suggestive of higher degrees of corneal staining. After entry of the scores per region, the total or composite (sum) score for each eye was automatically calculated (maximum score = 20/eye). A (+1) was added to the sum score for any eye with the presence of filaments.

Secondary outcomes

  1. Part 1: Change From Baseline in Central Corneal Fluorescein Staining

    Time frame: Up to 28 days (Baseline (BL) to end of randomized treatment)

    The degree of staining was based on the Corneal Fluorescein Modified NEI Scale. Central region was graded based on a scale of 0 to 4, with higher scores suggestive of higher degrees of corneal staining.

  2. Part 1: Change From Baseline in Inferior Corneal Fluorescein Staining

    Time frame: Up to 28 days (Baseline (BL) to end of randomized treatment)

    The degree of staining was based on the Corneal Fluorescein Modified NEI Scale. Inferior region was graded based on a scale of 0 to 4, with higher scores suggestive of higher degrees of corneal staining.

  3. Part 1: Percentage of Participants With Ocular and Non-ocular Treatment Emergent Adverse Events (AEs)

    Time frame: Up to 28 days (Baseline (BL) to end of randomized treatment)

    The number of treatment emergent ocular and non-ocular adverse events was reported categorically: Mild, Moderate, Severe.

    Treatment emergent adverse events (TEAEs) are adverse events started after the first administration of randomized study treatment or events present prior to start of the randomized treatment but increased in severity based on preferred term.
