  1. The study's listed conditions name Keratoconjunctivitis Sicca, a narrower term within Dry Eye Syndromes.
Confidence
High: the new condition is named in the study's own listed conditions. Of 351 hand-checked studies reclassified this way, 68% were exactly right and 84% in the right disease family; the registry's first term was right for 5% (measured 2026-10-21). How we classify →

Study 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).

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).

Inclusion criteria

  • Have a documented clinical diagnosis of dry eye disease in both eyes

Exclusion criteria

Exclusion Criteria:

  • Known / to study product(s) or components.
  • History of glaucoma, IOP >21 mmHg at the screening or randomization visits, or being treated for glaucoma in either eye.
  • Diagnosis of: ongoing ocular infection; severe/serious ocular condition that in judgment of Investigator could confound study assessments or limit compliance; severe/serious systemic disease or uncontrolled medical condition that in judgment of Investigator could confound study assessments or limit compliance; or have been exposed to an drug within the 30 days prior to screening.
  • In the opinion of Investigator or study coordinator, be unwilling or unable to comply with study protocol or unable to successfully instill eye drops.
Terms in these criteria, in plain language(3)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

Hypersensitivity

An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Investigational drug or device

A drug or device being studied in a clinical trial.

It may be new, or already approved and being studied for another use, dose or form. Criteria often leave out people who took part in another study of one within a recent period, commonly 30 days or five half-lives.

What researchers measure

Primary outcomes

  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.

    Time frame: 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.

    Time frame: Visit 6 (Day 29)

Secondary outcomes

  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.

    Time frame: 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.

    Time frame: 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.

The record gives a start of Jun 2014, a primary completion of Jan 2015 and a completion of Mar 2015. It does not say whether these dates are actual or estimated.

Results were first posted in Jan 2021, 6 years after primary completion. A results delay was requested in Jul 2016.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Jan 6, 2021, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
