Study summary

Autoimmune uveitis is one kind of non-infectious, sight-threatening, relapsing and severe ocular disease. Approximately 20%-25% autoimmune uveitis patients suffer from the dilemma of blindness for the chronic and persistent inflammatory state in the eyes, which results in continuous destroy in the structure of the eyes and gradually leads to irreversible damage on visual function. However, it shows limiting efficacy of current treatment including glucocorticoids, immunosuppressant and biologics for chronic autoimmune uveitis. Minocycline has been regarded to have anti-apoptosis and immunemodulatory function for decades and it has been illustrated to be beneficial in several neuro-degenerative and neuro-inflammatory diseases. This trial aims to investigate the efficacy and safety of minocycline for chronic autoimmune uveitis with retinal degenerative changes.

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

  • Participant diagnosed of diseases with visual function damage (decrease of BCVA, loss of retinal structure)
  • Participant aged from 18-60 years old.
  • Participant that signed the document and is able to complete the following visits.

Exclusion criteria

Exclusion Criteria:

  • Participant is allergy to minocycline or tetracyclines.
  • Participant has no of minocycline or tetracyclines.
  • Participant has an abnormal function of liver, heart, kidney and thyroid.
  • Participant is using , or biologics.
  • Female that is pregnant, breast-feeding or planning to become pregnant.
  • Participant that is currently using other medications for other diseases.
Terms in these criteria, in plain language(5)

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.

Autoimmune disease

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.

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.

Contraindication

A reason a treatment, test or procedure should not be given to a particular person, such as an allergy, another illness or a medicine they take.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

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.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

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 Apr 18, 2023, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
