Glanatec(R) for Descemet Stripping in Fuch's Endothelial Dystrophy
What this study is about
In brief, the objective of this study is to investigate whether the drug Glanatec ® which is approved in Japan for glaucoma and ocular hypertension, can be used in patients with Fuchs endothelial dystrophy who have had a descemet stripping procedure without endothelial keratoplasty.
View original scientific description
In brief, the objective of this study is to investigate whether the drug Glanatec ® which is approved in Japan for glaucoma and ocular hypertension, can be used in patients with Fuchs endothelial dystrophy who have had a descemet stripping procedure without endothelial keratoplasty. While some limited data exists as a proof of concept in in vitro or animal studies, and Glanatec® has been successfully used in a recently published case series for this indication, there is insufficient data to show that this drug can be effectively used for corneal cell clearing while maintaining patient safety. The goal of the study is to provide sufficient proof of concept for the use of this drug in patients with FED whose only treatment alternative is to undergo corneal transplant.
Who can participate
This study lists these criteria on ClinicalTrials.gov. A study coordinator reviews eligibility during screening — this page does not determine whether you qualify.
Inclusion criteria
- • Ability to understand read and sign the informed consent form.
- Age between 30 and \<91 years
- Ability to understand and follow instructions and study procedures
- Willingness to comply with all study procedures and be available for the duration of the study
- Ability to apply eye drop medication and willing to adhere to study medication regimen
- Diagnosed with Fuchs dystrophy (clinically and on confocal microscopy) by the study investigator.
- Pseudophakic FED with posterior capsule supported, suture-fixated, or sulcus-supported posterior chamber intraocular lens.
- Fuchs dystrophy grades 2-4 on the Krachmer grading scale
- Presence of central guttae deemed by the investigator to be the chief cause of visual symptoms, rather than cataract or corneal stromal edema
- Clear peripheral cornea with an endothelial cell count \>1000 cells/mm2 on specular microscopy
- Best corrected visual acuity in the study eye is 20/40 or worse at study enrollment
- The patient is dissatisfied with current vision
- The patient is otherwise to be offered a corneal graft
- For females with reproductive potential, willingness to use highly effective contraception (e.g., hormonal contraception, barrier contraception, intrauterine device, or abstinence).
- Indication for surgery may include cataract extraction and posterior chamber intraocular lens implantation
Exclusion criteria
- • Uncontrolled glaucoma (IOP \>25 mmHg)
- Presence of secondary corneal pathology such as infective or autoimmune keratitis
- Advanced corneal stromal edema defined as the presence of haze, bullae, or DM folds on slit-lamp biomicroscopy
- History of herpes simplex virus or cytomegalovirus keratitis
- Prior endothelial keratoplasty
- Aphakic in study eye.
- Allergy to any component of the Ripasudil hydrochloride hydrate 0.4% that will be used in the course of the study
- For women of child-bearing potential: Pregnant or lactating, or planning to become pregnant within the next 6 months.
- Any other ocular condition that, in the opinion of the investigator, may preclude the subject from study participation.

Frequently asked questions
What is a clinical trial?
A clinical trial is a research study that tests new medical treatments, drugs, devices, or procedures to determine their safety and effectiveness. Trials are carefully designed and monitored to protect participants while advancing medical knowledge.
Is it safe to participate?
Clinical trials follow strict safety guidelines and ethical standards. Trials must be reviewed and approved, and participants are closely monitored by medical professionals throughout the study. You can withdraw at any time if you choose.
Will I be compensated?
Many clinical trials offer compensation for your time, travel expenses, and inconvenience. The specific compensation varies by study and will be discussed during the screening process. All study-related medical care is typically provided at no cost to participants.
Will I receive a placebo instead of treatment?
When effective treatment exists, participants typically receive either the standard treatment plus the study intervention, or the standard treatment plus placebo. You would not be denied effective care. Placebos are primarily used when no proven treatment is available, or in addition to standard care. Your trial consent form will clearly explain what treatments you may receive.
Can I leave a trial if I change my mind?
Absolutely. Participation in clinical trials is completely voluntary. You have the right to withdraw from the study at any time, for any reason, without penalty or loss of benefits to which you are otherwise entitled.
How long does a clinical trial last?
Trial duration varies widely depending on the study design and purpose. Some trials last just a few weeks, while others may continue for months or years. The study coordinator will provide specific timeline information during your screening call.
