Safety and Efficacy of BAF312 in Dermatomyositis

9 december 2020 uppdaterad av: Novartis Pharmaceuticals

A Double Blind, Randomized, Placebo-controlled Study to Evaluate, Safety, Tolerability, Efficacy and Preliminary Dose-response of BAF312 in Patients With Active Dermatomyositis (DM)

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 .

Status

Avslutad

Detaljerad beskrivning

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.
