About Celladon

Celladon is a clinical-stage biotechnology company applying its leadership position in the field of cardiovascular gene therapy to develop novel therapies for diseases with tremendous unmet medical needs. Our lead programs target SERCA enzymes which are a family of enzymes that play an integral part in the regulation of intra-cellular calcium in all human cells. Calcium dysregulation is implicated in a number of important and complex medical conditions and diseases, such as heart failure, vascular disease, diabetes and neurodegenerative diseases. MYDICAR, the Company's most advanced product candidate, uses gene therapy to target SERCA2a, which is an enzyme that becomes deficient in patients with advanced heart failure. Celladon has completed enrollment of a 250 patient Phase 2b clinical trial evaluating the efficacy of MYDICAR in reducing the frequency of, or delaying heart failure-related hospitalizations. This randomized, double-blind, placebo-controlled, multinational trial is evaluating a single intracoronary infusion of MYDICAR versus placebo added to a maximal, optimized heart failure regimen in patients with New York Heart Association class III or IV symptoms of chronic heart failure due to systolic dysfunction. The Company has received Breakthrough Therapy designation from the FDA for this MYDICAR program and expects to report results from the Phase 2b clinical trial in April 2015. In addition, the Company conducts research and development on its membrane-bound form of the Stem Cell Factor (mSCF) gene therapy program for cardiac diseases. Celladon has also identified a number of potential first-in-class compounds addressing novel targets in diabetes and neurodegenerative diseases with its small molecule platform of SERCA2b modulators.
