Study summary

This study is a multicenter, prospective, observational cohort study designed to enroll a total of 340 patients undergoing allogeneic hematopoietic stem cell transplantation. Through comprehensive evaluations by hematology departments, ophthalmology departments, and patient-reported outcomes, the study aims to assess patient-reported outcomes, overall incidence, risk factors, and other clinical outcomes in patients with chronic ocular graft-versus-host disease following allogeneic hematopoietic stem cell transplantation.

Study population

Patients after all-HSCT

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

  • Age ≥14 years, both genders eligible;
  • First hematopoietic stem cell transplantation;

    • 100 days post-transplantation, with donor hematopoietic stem cell engraftment confirmed;
  • The subject or their legally authorized representative has provided full , signed the informed consent form, and is willing to complete subsequent follow-up visits

Exclusion criteria

Exclusion Criteria:

  • Preexisting moderate-to-severe ocular surface disease prior to transplantation;
  • Active ocular infection;
  • Presence of other ocular conditions that, in the opinion of the ophthalmologist, may significantly affect the diagnosis of chronic ocular , the evaluation of ocular surface parameters, or the completion of long-term follow-up;
  • Patients with active hematologic .
Terms in these criteria, in plain language(4)

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.

Allogeneic and autologous transplant

Stem cell (bone marrow) transplants. Allogeneic uses cells from a donor; autologous uses your own cells, collected earlier and given back.

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.

GVHD (graft-versus-host disease)

After a transplant from a donor, the donor’s immune cells attack the recipient’s body, often the skin, gut or liver.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

What researchers measure

Primary outcomes

  1. NEI-VFQ-25 scale

    The NEI-VFQ-25 (National Eye Institute Visual Function Questionnaire-25) is a 25-item, vision-specific patient-reported outcome measure. It assesses the impact of visual impairment on health-related quality of life

    Time frame: Two years after HSCT

Secondary outcomes

  1. EQ-5D-5L

    The EQ-5D-5L is a standardized, generic health status measure developed by the EuroQol Group. It is designed for self-completion and is widely used in clinical and economic evaluations.

    Time frame: Two years after HSCT

  2. Lee GVHD scale

    The Lee Chronic GVHD Symptom Scale is a patient-reported outcome (PRO) measure developed to assess the symptom burden of chronic graft-versus-host disease (cGVHD)

    Time frame: Two years after HSCT

  3. FACT-BMT

    The FACT-BMT (Functional Assessment of Cancer Therapy - Bone Marrow Transplantation) is a patient-reported outcome (PRO) measure designed to assess health-related quality of life (HRQoL) in patients undergoing bone marrow or hematopoietic stem cell transplantation

    Time frame: Two years after HSCT

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jun 2026 (actual). Primary completion is estimated for Jun 2030, 48 months after the start.

Of 49 non-industry observational studies under Bronchiolitis Obliterans Syndrome, half reached primary completion within 42 months of starting (the median), counting those still running; a quarter within 15 and three quarters within 75. This study's planned 48 months is above that.

Counting every sponsor, half of 57 studies reached it within 40 months; a quarter within 20 and three quarters within 62.

How these figures are worked out, and which studies are left out of them.

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 Aug 31, 2026, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
