Terms in these criteria, in plain language(7)

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.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

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.

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.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Childbearing potential

Able to become pregnant: from the first period until menopause, unless permanently unable to through surgery (removal of the womb, or of both ovaries or both fallopian tubes).

Criteria for people of childbearing potential usually ask for a negative pregnancy test and for contraception during the study and for a time after it.

Postmenopausal

Periods have stopped for good: usually no period for 12 months in a row without another medical reason, sometimes confirmed by a blood test (FSH).

Contraception

Ways of preventing pregnancy. “Highly effective” methods fail less than 1% of the time a year when used correctly — for example an IUD or an implant.

Criteria usually say which methods count and how long to keep using them after the last dose, sometimes for male participants too. Some studies accept a partner’s vasectomy if it was confirmed successful and that person is the participant’s only sexual partner.

What researchers measure

Primary outcomes

  1. Mean change in the tear film break-up time (TFBUT) from Visit 1 (baseline) to Visit 2 (day 14)

    Tear film break-up time (TBUT) will be assessed following the instillation of fluorescein solution into the eye. Fluorescein will be instilled at the outer canthus to avoid ocular surface damage, with the excess saline on the strip shaken off, or a reduced area fluorescein strip used. Viewing will take place between 1 and 3 min after instillation. Two measurements per eye will be performed and the mean value documented and used for evaluation.

    Time frame: baseline and week 2 follow up

Secondary outcomes

  1. Mean change in the tear film break-up time (TFBUT) from Visit 1 (baseline) to Visit 3 (day 28)

    Tear film break-up time (TFBUT) will be assessed following the instillation of fluorescein solution into the eye. Fluorescein will be instilled at the outer canthus to avoid ocular surface damage, with the excess saline on the strip shaken off, or a reduced area fluorescein strip used. Viewing will take place between 1 and 3 min after instillation. Two measurements per eye will be performed and the mean value documented and used for evaluation

    Time frame: baseline and week 4 follow up

  2. percent (%) change in the tear film break-up time (TFBUT) from Visit 1 (baseline) to Visit 2 (day 14) and from Visit 1 (baseline) to Visit 3 (day 28)

    Tear film break-up time (TFBUT) will be assessed following the instillation of fluorescein solution into the eye. Fluorescein will be instilled at the outer canthus to avoid ocular surface damage, with the excess saline on the strip shaken off, or a reduced area fluorescein strip used. Viewing will take place between 1 and 3 min after instillation. Three measurements per eye will be performed and the mean value documented and used for evaluation

    Time frame: baseline and week 2 follow-up; baseline and week 4 follow-up

  3. change in the tear film break-up time (TFBUT) on Visit 1 (day 1)

    Tear film break-up time (TBUT) will be assessed following the instillation of fluorescein solution into the eye. On Day 1 TBUT will be assessed at two time points (baseline and 4 hours post-dose). Fluorescein will be instilled at the outer canthus to avoid ocular surface damage, with the excess saline on the strip shaken off, or a reduced area fluorescein strip used. Viewing will take place between 1 and 3 min after instillation. Two measurements per eye will be performed and the mean value documented and used for evaluation.

    Time frame: baseline and 4 hour after 1st application

  4. Mean change in ocular surface disease index (OSDI) score from Visit 1 (baseline) to Visit 2 (day 14) and Visit 3 (day 28)

    Symptoms of DED will be assessed using the Ocular Surface Disease Index (OSDI) questionnaire at each visit. The 12-item OSDI questionnaire scores range from 0 to 100, it contains 3 ocular symptom questions, 6 vision-related function questions, and 3 environmental trigger questions. Each question score ranges from 0 ("none of the time") to 4 ("all of the time"). The total score is calculated based on the following formula: Total score: OSDI = (\[sum of scores for all questions answered\*100\]/\[total number of questions answered\*4\]).

    Time frame: baseline, week 2 follow-up and week 4 follow-up

  5. Mean changes in ocular surface staining score (OSS) (total corneal and total conjunctival staining score) from Visit 1 (baseline) to Visit 2 (day 14) and Visit 1 to Visit 3 (day 28)

    Ocular surface staining of five corneal regions and six conjunctival regions will be observed at each visit by slit-lamp examination after instillation of fluorescein respectively. Surface staining will be scored as 0 (normal, no staining), 1 (mild, superficial stippling or macropunctate staining), 2 (moderate, macropunctate staining with some coalescent areas), or 3 (severe, numerous coalescent macropunctate areas or patches). Scores will be summed to yield total corneal and total conjunctival staining scores for each eye.

    Time frame: baseline, week 2 follow-up and week 4 follow-up

  6. Change in Dry Eye Symptom Score (DESS) on Visit 1 (day 1)

    Dry Eye Symptom Score will be assessed, using a 10-point Likert scale, where 0 indicates no symptoms and 10 indicates the most severe symptoms, based on the change from baseline in dry eye symptom scores on day 1 (baseline and 0, 4, and 8±1 hours after 1st dose application). Median values will be documented and used for evaluation.

    Time frame: baseline and 0, 4 and 8±1 hour after 1st application

  7. Change in Soothing Sensation Score (SSS) on Visit 1 (day 1)

    Soothing Sensation Score will be assessed, using a 10-point Likert scale, where 0 indicates no symptoms and 10 indicates the most severe symptoms, based on the change from baseline in soothing sensation scores on day 1 (baseline and 0, 4, and 8±1 hours after 1st dose application). Median values will be documented and used for evaluation.

    Time frame: baseline and 0, 4 and 8±1 hour after 1st application

  8. Change in Refreshing Effect Score (RES) on Visit 1 (day 1)

    Refreshing Effect Score will be assessed, using a 10-point Likert scale on day 1 (0, 0.25 and 1 hour after 1st dose application), where 0 indicates no symptoms and 10 indicates the most severe symptoms. Median values will be documented and used for evaluation.

    Time frame: 0, 0.25 and 1 hour after 1st application

Other outcomes

  1. The presence of Adverse Event/ /Serious Adverse Event (AE/ /SAE) throughout the investigation period

    The patients will be asked to report any Pre-Treatment Sign and symptom/Adverse Events (PTSS/AEs) spontaneously.

    Time frame: baseline, week 2 follow-up and week 4 follow-up

  2. Best-corrected visual acuity (BCVA)

    Best corrected visual acuity (BCVA) will be assessed at each visit. BCVA assessment will be at 4 meters using an ETDRS chart (The Early Treatment Diabetic Retinopathy Study Group). Results will be calculated as logMAR scores. The logMAR scale (logarithm of the Minimum Angle of Resolution) ranges approximately from -0.3 to 1.0, where lower scores indicate better visual acuity and higher scores indicate worse visual acuity.

    Time frame: baseline, week 2 follow-up and week 4 follow-up

  3. Frequency of ocular signs

    Ocular signs will be assessed by slit-lamp examination at all study visits. The following signs will be assessed: • active inflammation or significant structural change or discharge (eyelids and conjunctiva); • active inflammation or active structural change, including focal scarring and fine deposition (cornea); • active inflammation (iris and anterior chamber); • level of lens opacity, pseudophakia, or aphakia (lens, with an emphasis on the visual axis)

    Time frame: baseline, week 2 follow-up and week 4 follow-up

  4. Change in tolerability assessment score (TAS) on Visit 1 (day 1)

    Tolerability Assessment Score will be assessed on Day 1 following instillation. The symptoms (burning sensation, stinging sensation, blur, and foreign body sensation) will be evaluated using a a 10-point Likert scale, where 0 indicates no symptom and 10 indicates the most severe symptom. Tolerability Assessment Score will be listed and evaluated descriptively (number of patients (N), arithmetic mean, standard deviation (SD), median, minimum, and maximum). Results for 0-5 and 6-10 scores will be summarized using counts and percentages.

    Time frame: Day 1

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Ran from Mar 2024 to primary completion in Aug 2024, 5 months.

Of 81 industry-sponsored phase 3 interventional studies under Dry Eye Syndromes, half reached primary completion within 9 months of starting (the median), counting those still running; a quarter within 6 and three quarters within 15. This study's 5 months is below that.

Counting every sponsor, half of 96 studies reached it within 10 months; a quarter within 7 and three quarters within 15.

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 Jul 3, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
