Study summary

The study will perform to follow-up UC-MSCs and CM transplantation. 18 patients will be called back to be examined after 5 years of UC-MSC and/or CM transplantation.

Read the detailed description

The study will be performed on 18 patients who received UC-MSC and CM transplantation in 2018. The study is included as retrospective cohort since the transplantation happened 5 years ago. Patients will do a visual field test, visual acuity test, electroretinography, funduscopy, and Optical Coherence Tomography examination. The observation results will be written in the observation table and analyzed by a statistic.The study will be performed at Rumah Sakit Jakarta Eye Center and Rumah Sakit Umum Pusat Dr. Sardjito Yogyakarta.

Study population

Retinitis Pigmentosa patients who have been transplanted UC-MSC and/or CM 5 years ago under clinical trials NCT04315025

Go through the criteria one by one — yes, no or not sure — and take the list to your doctor or the study team. Kept in this browser only.

Inclusion criteria

  • Visual field defects at the initial examination with Humphrey perimetry are between 25% to 50%
  • Willing to sign as research subjects
  • Willing to do the peribulbar injection with mesenchymal stem cells isolated from umbilical cord tissue
  • Willing to do visual field checks with Humphrey's perimetry, vision tests with Snellen boards, Optical Coherent Tomography (OCT) examinations, electroretinogram examinations and fill out a quality of life questionnaire

Exclusion criteria

Exclusion Criteria:

  • Pregnant or nursing women
  • Positive result of test
  • Have a history of eye tumours
  • In the treatment or other drugs that can affect the growth of transplanted stem cells
  • Have another eye disease such as diabetic retinopathy, uveitis, cataract, and glaucoma
  • Do not come to control according to the schedule determined by the researcher (loss to follow up)
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.

Informed consent

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.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Interventions

06

What researchers measure

Primary outcomes

  1. Visual Acuity Test

    a test to see the sharpness of vision using Snellen Chart which is read at a distance of 6 meters. Normal eye test results are stated in 6/6.

    Time frame: 5 years after injection

  2. Visual Field Test

    a test to assess the breadth of views of the lateral, medial, superior and inferior aspects using Humprey's perimetry.

    Time frame: 5 years after injection

  3. Funduscopy

    an examination to see and assess the abnormalities and conditions in the ocular fundus using an ophthalmoscope. This examination is carried out by an ophthalmologist.

    Time frame: 5 yeas after injection

  4. Electrorectinography

    an examination to provide a picture of objectivity, a quantitative measure of retinal function to monitor the function of stem cells and ganglion cells in the eye. This examination is carried out by a trained ophthalmologist.

    Time frame: 5 years after injection

  5. Optical Coherence Tomography (OCT)

    is a diagnostic test that give the information about posterior segment structure, which is retina and optic nerve papillae so that it can be used to assess macular abnormalities

    Time frame: 5 years after injection

  6. Angiography

    a process of taking photos of the retina by injecting fluorescent to get a bleeding location on the retina.

    Time frame: 5 years after injection

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