What this trial studies

This study investigates the transplantation of umbilical cord-derived mesenchymal stem cells (UC-MSC) and conditioned medium (CM) to inhibit vision loss in patients with Retinitis Pigmentosa. Participants will be divided into two groups receiving different dosages of UC-MSC, either 1.5 million or 5 million cells, administered via a peribulbar injection. The study will monitor patients for six months, assessing visual function and potential complications through various eye examinations. The aim is to evaluate the safety and efficacy of this innovative treatment approach.

Who should consider this trial

Good fit: Ideal candidates are individuals with Retinitis Pigmentosa who have a visual acuity better than 20/100 and meet specific electrophysiological criteria.

Not a fit: Patients with other eye diseases, a history of eye tumors, or those undergoing immunosuppressive treatment may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could significantly slow or prevent vision loss in patients with Retinitis Pigmentosa.

How similar studies have performed: While the use of stem cells in ophthalmology is an emerging field, this specific approach has not been widely tested, making it a novel investigation.
