Daclizumab and Sirolimus to Treat Uveitis

We propose to investigate the possible efficacy of combination daclizumab and sirolimus therapy to induce peripheral immune tolerance in participants presenting with non-infectious intermediate and posterior uveitis. This will be performed using a Phase I/II pilot study. Subjects on daclizumab monotherapy will receive a 6 mg loading dose of oral sirolimus at week 0, followed by a 2 mg dose every other day for 2 weeks. If tolerated, the subject will be increased to a 2 mg daily dose. After one year of combination therapy, the subject will be tapered off daclizumab first and then sirolimus. The primary outcome will be the ability of the participant to be successfully tapered off daclizumab and sirolimus while their disease remains quiet (vitreous haze less than or equal to Trace) for 24 weeks on no systemic immunosuppressive medications (approximately week 134).
