About this study

Official title: A Phase II, Double-Masked, Randomized, Controlled Study of KPI-121 0.25% Ophthalmic Suspension Compared to Vehicle in Subjects With Dry Eye Disease

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).

Read the detailed 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).

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • KPI-121Drug

    Also called KPI-121 0.25% Ophthalmic Suspension, Loteprednol etabonate

    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.

  • PlaceboDrug

    Also called Vehicle of KPI-121 0.25% Ophthalmic Suspension

    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.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. 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.

    Measured: Visit 6 (Day 29)

  2. 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.

    Measured: Visit 6 (Day 29)

Secondary outcomes (3)
  1. 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.

    Measured: Visit 4 (Day 15) and Visit 6 (Day 29)

  2. 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.

    Measured: Visit 4 (Day 15)

  3. 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.

    Measured: Visit 4 (Day 15)

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 1 inclusion and 4 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 6 Jan 2021. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 11 sites in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. Some participants in this study may receive a placebo. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

Yes. Results are posted in the registry (first posted 6 Jan 2021). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Bulbar Conjunctival Hyperemia (time frame: Visit 6 (Day 29)). The study lists 2 primary outcomes in all. It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02188160, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jan 2021.
