Healthy volunteers: no

Brief summary:
This study investigated the dose response relationship for the efficacy and safety of BAF312 compared to placebo in active DM patients over a treatment period of 6+6 months and to determine the minimum dose required for a maximal clinical effect. The study was composed of 2 periods: a double-blind period 1 with BAF312 administered at different daily doses (0.5, 2, 10 mg and placebo) and a fixed-dose Period 2 in which BAF312 was administered at the dose of 2 mg daily .

Detailed description:
The study was prematurely terminated based on the results of an interim analysis where BAF312 did not demonstrate superior efficacy over placebo and a dose-response relationship was not observed. There were no safety concerns. Approximately 56 participants were planned to be randomized. A total of 17 participants were enrolled and randomized by the time the study was terminated.

Arms:
arm 1: During period 1, participants were uptitrated daily from BAF312 0.25 mg to 0.5 mg over a 10 day period. After, participants continued on 0.5 mg daily for up to 24 weeks. During period 2, participants were uptitrated daily from BAF312 0.25 mg to 2.0 mg over a 10 day period. After, participants continued on 2.0 mg daily for up to 24 weeks. arm 2: During period 1, participants were uptitrated daily from BAF312 0.25 mg to 2.0 mg over a 10 day period. After, participants continued on 2.0 mg daily for up to 24 weeks. During period 2, participants were uptitrated daily from BAF312 0.25 mg to 2.0 mg over a 10 day period. After, participants continued on 2.0 mg daily for up to 24 weeks. arm 3: During period 1, participants were uptitrated daily from BAF312 0.25 mg to 10.0 mg over a 10 day period. After, participants continued on 10.0 mg daily for up to 24 weeks. During period 2, participants were uptitrated daily from BAF312 0.25 mg to 2.0 mg over a 10 day period. After, participants continued on 2.0 mg daily for up to 24 weeks. arm 4: During period 1, participants received matching placebo daily for up to 24 weeks. During period 2, participants were uptitrated daily from BAF312 0.25 mg to 2.0 mg over a 10 day period. After, participants continued on 2.0 mg daily for up to 24 weeks.

Interventions: intervention 1: BAF312 intervention 2: Placebo
Intervention descriptions: intervention 1: BAF312 was provided as film-coated tablets in strengths of 0.25, 0,5, 1 and 2 mg for oral administration. intervention 2: Matching placebo to BAF312 as tablets for oral administration.
