Study information

Study designOpen-label parallel-assignment randomised controlled trial
Primary study designInterventional
Secondary study designRandomised parallel trial
Study setting(s)Not specified
Study typeTreatment
Scientific titleMulticenter Uveitis Steroid Treatment Trial
Study acronymMUST
Study objectivesUveitis 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.

1. Protocol version 1.1, approved on the 18/05/2005
2. Protocol version 3.3, approved on the 03/09/2008
3. Protocol version 3.4, approved on the 13/08/2009
Health condition(s) or problem(s) studiedUveitis
InterventionIntervention 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 typeDrug
Pharmaceutical study type(s)
PhaseNot Applicable
Drug / device / biological / vaccine name(s)Fluocinolone acetonide, corticosteroid, immunosuppressive agents
Primary outcome measureChange 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 measures1. 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
Overall study start date01/12/2005
Completion date31/12/2011
