Efficacy of Topical Mesenchymal Stromal Cell Secretome for Ocular Surface Disease
What this study is about
In this phase II randomly assigned double-masked clinical trials, subjects with non-resolving corneal epithelial disease/defect (i.e., refractory to standard treatments for at least two weeks) will receive 8 weeks treatment of topical mesenchymal stem cell secretome or vehicle, with continued follow-up for up to Day 70.

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
- Age · Patients 18 years of age or older
- Ocular Health
- Chronic corneal epithelial disease with fluorescein staining score 6 by NEI grading scale or persistent corneal epithelial defect present for longer than 14 days despite standard treatment
- No objective clinical evidence of significant (\> 50%) improvement/worsening of the epithelial disease in the last 14 days
- Epithelial disease refractory to conventional non-surgical treatments (e.g., preservative-free artificial tears, gels or ointments; discontinuation of preserved topical drops; anti-inflammatory therapy)
- If both eyes of subject meet the inclusion criteria, the eye with the higher fluorescein staining score will be enrolled to the study.
- Study Procedures
- Only patients who satisfy all Informed Consent requirements may be included in the study. The patient and/or his/her legal representative must read, sign and date the Informed Consent document before any study-related procedures are performed. The Informed Consent form signed by patients and/or legal representative must have been approved by the UIC IRB for the current study. Patients must have the ability and willingness to comply with study procedures.
Exclusion criteria
- Ocular Health
- Any active or suspected ocular infection (bacterial, viral, fungal or protozoal).
- History of any ocular surgery (including laser or refractive surgical procedures) in the study eye within the 3 months prior to study enrollment.
- Treatment with Oxervate in the study eye within 12 months of enrollment.
- Study Procedures
- Known hypersensitivity to one of the components of the study or procedural medications (e.g., fluorescein).
- Use of any investigational agent within 4 weeks of screening visit.
- Participation in another clinical study at the same time as the present study.
- Participants who are pregnant at the time of study enrollment.

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.
