Safety and Efficacy of BAF312 in Dermatomyositis

December 9, 2020 updated by: 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 .

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.

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Change From Baseline in Manual Muscle Testing - 24 Muscles (MMT-24) Score
Time Frame: Baseline, 6 months
Each muscles tested was evaluated on a 0 - 10 scale where 0 indicated the weakest muscle score and 10 indicated the strongest muscle score. The total MMT24 score ranged from 0 - 240, where an increasing trend in the values indicates improvement. A positive change from baseline indicates improvement.
