Clinical Trial Summary

The primary purpose of this study is to determine the efficacy and safety of KPI-121 0.25% ophthalmic suspension compared to vehicle (placebo) in subjects who have a documented clinical diagnosis of dry eye disease. The product will be studied over 28 days, with 1-2 drops instilled in each eye four times daily (QID).


Description:

This is a Phase II, multi-center, double-masked, randomized, vehicle-controlled, parallel-group study designed to evaluate the safety and efficacy of KPI-121 0.25% ophthalmic suspension versus vehicle in subjects with dry eye disease. Approximately 400 subjects will be screened and up to 150 subjects will be randomized at up to 12 centers located in the United States. Subjects will be randomized to 1 of 2 study arms in an approximate 1:1 ratio. The study arms are: 1) KPI-121 0.25% ophthalmic suspension administered 1-2 drops in each eye QID for up to 28 days or 2) vehicle administered as 1-2 drops in each eye QID for up to 28 days. This study will include up to 6 clinic visits over 6 weeks. At Visit 1 Screening (14 ± 1 days prior to Day 1), subjects who meet screening inclusion/exclusion criteria will begin a 2-week run-in period during which they will be treated with 1-2 drops of single-masked vehicle in each eye QID for 14 ± 1 days. At Visit 2, Randomization (Day 1), subjects who continue to meet inclusion/exclusion criteria will be eligible for randomization to 1 of the 2 arms of the study (i.e., KPI-121 0.25% ophthalmic suspension or vehicle). Following randomization, subjects will be instructed to return to the clinic to have a complete study evaluation at Study Visits 4 and 6 (Days 15 ± 1 day and 29 ± 1 day, respectively). Subjects will further be instructed to return to the clinic for diary collection and in-clinic symptom assessment only at Visits 3 and 5 (Days 8 ± 1 day and 22 ± 1 day, respectively). The last dose of investigational product and the final study visit will occur upon completion of 28 ± 1 days of exposure to investigational product. Subjects will be released from the study at the end of Visit 6 (Day 29 ± 1 day).

Study Design


Intervention

Drug:
KPI-121
KPI-121 drug product will be supplied as 0.25% as a suspension in identically packaged opaque dropper bottles. KPI-121 drug product is a sterile, aqueous, submicron suspension of loteprednol etabonate.
Placebo
Subjects randomized to placebo control arms will receive the same bottles containing all components at the concentrations used in the KPI-121 drug product with the exception of the active component, loteprednol etabonate.

Outcome

Type Measure Description Time frame Safety issue
Primary Bulbar Conjunctival Hyperemia Comparison of mean bulbar conjunctival hyperemia in the study eye between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-4 grading scale. The grading scale was based on the Cornea and Contact Lens Research Unit Grading Scale where 0 = none, 1 = very slight, 2 = slight, 3 = moderate and 4 = severe. Visit 6 (Day 29)
Primary Ocular Discomfort Comparison of mean ocular discomfort severity between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-100 visual analog grading scale where 0 was better and 100 was worse. Visit 6 (Day 29)
Secondary Corneal Fluorescein Staining Scores Comparison of mean corneal fluorescein staining scores in the study eye between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using methods developed by the National Eye Institute (NEI) Dry Eye Workshop in evaluating 5 regions of the cornea (superior, inferior, nasal, temporal and central) using a 0-3 grading scale, where 0 = no visible staining, 1 = Mild, 2 = moderate and 3 = severe. The total score is obtained by summing each of the 5 sections of the cornea. The NEI score will be from 0-15. Visit 4 (Day 15) and Visit 6 (Day 29)
Secondary Bulbar Conjunctival Hyperemia Scores Comparison of mean bulbar conjunctival hyperemia scores in the study eye between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-4 grading scale. The grading scale was based on the Cornea and Contact Lens Research Unit Grading Scale where 0 = none, 1 = very slight, 2 = slight, 3 = moderate and 4 = severe. Visit 4 (Day 15)
Secondary Ocular Discomfort Comparison of mean ocular discomfort severity between the KPI-121 0.25% ophthalmic suspension group and the vehicle group using a 0-100 visual analog grading scale where 0 was better and 100 was worse. Visit 4 (Day 15)
