A randomized clinical trial comparing methotrexate and mycophenolate mofetil for noninfectious uveitis. Ophthalmology. 2014 Oct;121(10):1863-70. doi: 10.1016/j.ophtha.2014.04.023

OBJECTIVE: To compare the relative effectiveness of methotrexate and mycophenolate mofetil for noninfectious intermediate uveitis, posterior uveitis, or panuveitis.

DESIGN: Multicenter, block-randomized, observer-masked clinical trial.

PARTICIPANTS: Eighty patients with noninfectious intermediate, posterior, or panuveitis requiring corticosteroid-sparing therapy at Aravind Eye Hospitals in Madurai and Coimbatore, India.

INTERVENTION: Patients were randomized to receive 25 mg weekly oral methotrexate or 1 g twice daily oral mycophenolate mofetil and were monitored monthly for 6 months. Oral prednisone and topical corticosteroids were tapered.

MAIN OUTCOME MEASURES: Masked examiners assessed the primary outcome of treatment success, defined by achieving the following at 5 and 6 months: (1) ≤0.5+ anterior chamber cells, ≤0.5+ vitreous cells, ≤0.5+ vitreous haze and no active retinal/choroidal lesions in both eyes, (2) ≤10 mg of prednisone and ≤2 drops of prednisolone acetate 1% a day, and (3) no declaration of treatment failure because of intolerability or safety. Additional outcomes included time to sustained corticosteroid-sparing control of inflammation, change in best spectacle-corrected visual acuity, resolution of macular edema, adverse events, subgroup analysis by anatomic location, and medication adherence.

Forty-one patients were randomized to methotrexate and 39 to mycophenolate mofetil. A total of 67 patients (35 methotrexate, 32 mycophenolate mofetil) contributed to the primary outcome. Sixty-nine percent of patients achieved treatment success with methotrexate and 47% with mycophenolate mofetil (P = 0.09). Treatment failure from adverse events or tolerability was not different by treatment arm (P = 0.99). There were no differences between treatment groups in time to corticosteroid-sparing control of inflammation (P = 0.44), change in best spectacle-corrected visual acuity (P = 0.68), or resolution of macular edema (P = 0.31).

CONCLUSIONS: There was no statistically significant difference in corticosteroid-sparing control of inflammation between patients receiving methotrexate or mycophenolate mofetil. However, there was a 22% difference in treatment success favoring methotrexate.
