Study information
Scientific title
Multicenter Uveitis Steroid Treatment Trial
Acronym
MUST
Study hypothesis
Uveitis refers to several ocular disorders characterised by intraocular inflammation, which in the aggregate are a major cause of visual loss and blindness in the United States. Intermediate uveitis, posterior uveitis, and panuveitis are generally the more severe forms of uveitis, with the highest risk of vision loss, often requiring long-term systemic treatment.
1. Patients randomised to implant therapy will have better visual outcomes.
2. Patients randomised to implant therapy will have improved control of uveitis, a decreased rate of posterior segment structural complications of the uveitis (such as cystoid macular edema and epiretinal membranes), and an increased rate of corticosteroid-induced ocular complications, such as cataracts, ocular hypertension, and glaucoma.
3. Patients randomised to systemic therapy will have a higher rate of systemic complications, such as diabetes, hypertension, and osteoporosis.
4. Improved visual outcomes and the absence of systemic corticosteroid complications (and the additional treatments needed to combat them) will result in a better quality of life for patients randomised to implant therapy.

Patient information sheet
Condition
Uveitis
Intervention
Intervention group: fluocinolone acetonide intraocular implant
Control group: oral corticosteroid with immunosuppressive agents as needed
The fluocinolone acetonide intraocular implant is a surgically implanted reservoir of corticosteroid designed to last approximately 2.5 years in order to provide long-term control of uveitis.
Total duration of follow-up: Minimum of 2 years (patients enrolled early in the study will be followed for up to 5 years)
Intervention type
Drug
Phase
Not Applicable
Drug names
Fluocinolone acetonide, corticosteroid, immunosuppressive agents
Primary outcome measure
Change in best-corrected visual acuity as measured by a logarithmic chart (measured at every study visit). Total duration of follow-up: 2 years
Secondary outcome measures
1. Occurrence of ocular complications
2. Occurrence of systemic complications
3. Control of uveitis
4. Quality of life at baseline and 6 months, assessed using the 25-item National Eye Institute Visual Function Questionnaire (NEI VFQ-25) and the 36-item Short Form health survey (SF-36)
5. Mortality. Total duration of follow-up: 2 years.
The following tests will also be carreid out to assess the outcomes 1-3 above:
a. Eye exam/blood draw (laboratory) at every study visit
b. Visual field testing at baseline and yearly thereafter
