Study Summary

This is a randomized, double-blind, placebo-controlled study in patients with dilated cardiomyopathy (DCM) due to a mutation of the gene encoding the lamin A/C protein (LMNA). The study will further evaluate a dose level of study drug (ARRY-371797) that has shown preliminary efficacy and safety in this patient population. After the primary analysis has been performed, eligible patients may receive open-label treatment with ARRY-371797.

Primary Outcome

The 6 MWT was an assessment where the distance that a participant could walk on a flat and hard surface in 6 minutes was measured. Participants were asked to perform the test at a pace that was comfortable to them, with as many breaks as they needed, and under supervision of a qualified professional. Study discontinuation \& death were incorporated into endpoint definition through ranking in hypothesis testing of treatment difference. Missing data resulting from study discontinuation were impute
