Eligibility criteria

Key Inclusion Criteria:

  1. Age ≥ 18 years.
  2. Subject has uncomplicated history of cataract that has progressed to a level requiring standard cataract extraction with intraocular lens implant surgery.
  3. Decreased endothelial cell count

Exclusion Criteria:

All ocular criteria apply to study eye unless otherwise noted.

  1. Other corneal disease
  2. Macular disease that in the investigator and/or sponsor's opinion would limit the ability of the subject to demonstrate improvement in BCVA.
  3. Descemet membrane detachment.
  4. History of uveitis or other ocular inflammatory disease.
  5. History of incisional glaucoma surgery
  6. Prior incisional eye surgery within 3 months prior to study treatment or penetrating or endothelial keratoplasty.
  7. History of ocular neoplasm.
  8. ETDRS BCVA in the fellow eye is worse than 35 letters (Snellen equivalent of 20/200).
  9. Female who is pregnant, nursing, or planning to become pregnant, or who is of and not using a reliable means of during the study.
  10. Subject is currently participating in or has participated within the last 3 months in any other clinical trial of an drug by ocular or systemic administration.
  11. Any concomitant medical or psychological condition that could interfere with study participation or is otherwise not suitable for entry into the study in the opinion of the investigator.
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.

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.

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 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 Dec 8, 2025, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
