A Phase 4 interventional study of Ripasudil hydrochloride hydrate 0.4% ophthalmic solution in Fuchs' Endothelial Dystrophy, sponsored by Marian Macsai, MD. Recruiting at 1 site in United States. Open to participants aged 18 Years to 91 Years. Per ClinicalTrials.gov, last updated 2021-08-11.
Sponsored by Marian Macsai, MD · Phase 4, Interventional, and Treatment
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.
92 studies on the registry are indexed under Fuchs' Endothelial Dystrophy; 27 are open to participants now.
This study's planned enrollment of 30 is below the median of 50 across 62 interventional studies indexed under Fuchs' Endothelial Dystrophy.

Ability to understand read and sign the form.
Exclusion Criteria:
Uncontrolled glaucoma (IOP >25 mmHg)
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.
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.
Able to have children. For women this usually means from the first period until menopause, unless permanently unable to through surgery; for men, unless permanently sterile. Read who the line is about — participants, women, men, or their partners.
Criteria about it usually ask for contraception during the study and for a time after it.
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.
A condition in which the immune system attacks the body’s own tissues, such as rheumatoid arthritis, lupus, psoriasis, type 1 diabetes or inflammatory bowel disease.
Immunotherapy studies often leave out active autoimmune disease, and some name exceptions, such as thyroid disease on replacement hormone. Check the exceptions this study lists.
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.

Drug: Ripasudil hydrochloride hydrate 0.4% ophthalmic solution
Drug: Ripasudil hydrochloride hydrate 0.4% ophthalmic solution
the ophthalmic solution will be administered three or six per times per day in the eye designated as the "Study Eye" upon study enrollment
Also known as: Glanatec
Corneal Clearing
The first primary aim of this study is to examine whether Glanatec® administered three or six times daily significantly increases corneal clearing at 12 months versus baseline in patients with Fuchs endothelial dystrophy (FED) undergoing Descemet stripping
Time frame: 12 months
pachymetry measurement
The second primary aim of this study is to examine whether Glanatec® administered three or six times daily significantly reduces the pachymetry measurement at 12 months versus baseline in patients with Fuchs endothelial dystrophy (FED) undergoing Descemet stripping.
Time frame: 12 months
Visual Acuity
The secondary aim of this study is to examine whether Glanatec® administered three or six times daily affects best corrected visual acuity at 12 months (measured by Snellen lines) as compared to baseline, patients with Fuchs endothelial dystrophy (FED) undergoing Descemet stripping.
Time frame: 12 months
