Study summary

The objective of this pivotal trial is to assess the efficacy, safety and tolerability of CyclASol in comparison to the vehicle for the treatment of signs and symptoms of Dry Eye Disease (DED).

Read the detailed description

This Phase 3 study will assess the efficacy, safety and tolerability of CyclASol 0.1% Ophthalmic Solution administered bilaterally twice daily versus vehicle.

No

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Signed ICF ( Form)
  • Patient-reported history of DED in both eyes
  • Current use of OTC (over-the-counter) and/or artificial tears for dry eye symptoms
  • Ability and willingness to follow instructions, including participation in all study assessments and visits

Exclusion criteria

Exclusion Criteria:

  • Women who are pregnant, nursing or planning a pregnancy
  • Unwillingness to submit a urine pregnancy test at screening and the last visit (or early termination visit) if of , or unwillingness to use acceptable means of
  • slit-lamp findings or abnormal lid anatomy at screening
  • Ocular/periocular
  • History of herpetic keratitis
  • Active ocular allergies or ocular allergies that may become active during the study period
  • Ongoing ocular or systemic infection at screening or baseline
  • Wear of contact lenses within 3 months prior to screening or anticipated use of contact lenses during the study
  • Use of topical Cyclosporine A or Liftigrast within 2 months prior to screening

  • Presence of uncontrolled systemic diseases
  • Presence of known allergy and/or sensitivity to the study drug or its components
  • Randomized in a previous CyclASol trial
Terms in these criteria, in plain language(5)

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.

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.

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.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

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.

What researchers measure

Primary outcomes

  1. Change From Baseline in Total Corneal Fluorescein Staining

    Total Corneal Fluorescein Staining (tCFS) is graded based on the National Eye Institute (NEI) scale. The NEI scale divides the cornea in 5 subregions: central, inferior, superior, nasal, temporal. The score for each region ranges from 0-3; 0 corresponds to no staining (best), 3 corresponds to maximum staining (worst). The total score is the sum of the 5 subregions ranging from 0 (best) - 15 (worst).

    Time frame: baseline and 1 month [day 29]

  2. Change From Baseline in Eye Dryness Score

    Eye dryness score is rated on a visual analogue scale (VAS) ranging from 0-100; 0 corresponds to no discomfort and 100 to maximum discomfort.

    Time frame: baseline and 1 month [day 29]

Secondary outcomes

  1. Change From Baseline in Total Conjunctival Lissamine Green Staining

    Conjunctival staining was assessed by the investigator in the nasal and temporal sections. The Oxford Scheme was used for each section, with a possible score of 0-5 for each section, where 0=absent and 5=severe. The nasal and temporal scores were summed, for a possible score of 0-10 for each eye.

    Time frame: baseline and 1 month [day 29]

  2. Proportion of Responders in Central Corneal Fluorescein Staining Score

    ≥ 1 score improvement for cCFS on National Eye Institute (NEI) scale: Central Corneal Fluorescein Staining (cCFS) is graded based on the NEI scale. The NEI scale divides the cornea in 5 subregions: central, inferior, superior, nasal, temporal. The score for each region ranges from 0-3; 0 corresponds to no staining (best), 3 corresponds to maximum staining (worst).

    Time frame: baseline and 1 month [day 29]

  3. Proportion of Responders in Total Corneal Fluorescein Staining Score

    ≥ 3 scores improvement for tCFS on National Eye Insititute (NEI) scale: Total Corneal Fluorescein Staining (tCFS) is graded based on the NEI scale. The NEI scale divides the cornea in 5 subregions: central, inferior, superior, nasal, temporal. The score for each region ranges from 0-3; 0 corresponds to no staining (best), 3 corresponds to maximum staining (worst). The total score is the sum of the 5 subregions ranging from 0 (best) -15 (worst).

    Time frame: baseline and 1 month [day 29]

  4. Change From Baseline in Central Corneal Fluorescein Staining

    Central Corneal Fluorescein Staining (cCFS) is graded based on the National Eye Institute (NEI) scale. The NEI scale divides the cornea in 5 subregions: central, inferior, superior, nasal, temporal.

  5. Change From Baseline in Total Corneal Fluorescein Staining

    Total Corneal Fluorescein Staining (tCFS) is graded based on the National Eye Institute (NEI) scale. The NEI scale divides the cornea in 5 subregions: central, inferior, superior, nasal, temporal. The score for each region ranges from 0-3; 0 corresponds to no staining (best), 3 corresponds to maximum staining (worst). The total score is the sum of the 5 subregions ranging from 0 (best) - 15 (worst).

    Time frame: baseline and 2 weeks [day 15]

  6. Change From Baseline in Visual Analogue Scale (VAS) for Blurred Vision

    Blurred vision score is rated on a visual analogue scale (VAS) ranging from 0-100; 0 corresponds to no discomfort and 100 to maximum discomfort.

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 Dec 2020 to primary completion in Sep 2021, 8 months.

Results were first posted in Mar 2023, 1 year 6 months after primary completion.

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 8 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.

How these figures are worked out, and which studies are left out of them.

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 Mar 10, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
