Celladon Reports Fourth Quarter and Year-End 2013 Financial

SAN DIEGO, March 31, 2014 (GLOBE NEWSWIRE) -- Celladon Corporation (Nasdaq: CLDN ), a clinical-stage biotechnology company focused on developing novel therapies by applying its leadership position in the field of SERCA enzymes, today announced financial results for the quarter and year ended December 31, 2013.

"Celladon executed on key operational and financial objectives in 2013. With the recent completion of enrollment of our CUPID 2 trial of MYDICAR in advanced heart failure and the closing of our IPO, we are setting the stage for another productive year ahead," said Krisztina Zsebo Ph.D., President and Chief Executive Officer.

2013 and Recent Corporate Highlights

MYDICAR

-- In February 2014 we completed enrollment in the Phase 2b study with lead product candidate MYDICAR. This trial, "Calcium Up-Regulation by Percutaneous Administration of Gene Therapy In Cardiac Disease" (the "CUPID 2 Trial") is a multinational, multicenter, double-blind, placebo-controlled, randomized study comparing a single intracoronary administration of MYDICAR versus placebo added to an optimal heart failure regimen. The primary objective is to determine the efficacy of MYDICAR in patients with ischemic or dilated cardiomyopathy and NYHA class III/IV symptoms of heart failure by reducing the frequency and/or delaying heart failure-related hospitalizations compared to placebo-treated patients. Secondary objectives include assessment of the safety of MYDICAR by determining the incidence and severity of adverse events and changes in laboratory parameters. A total of 250 patients were enrolled and data from this trial is expected in April 2015.

-- In November 2013, the European Medicines Agency (EMA) indicated that if MYDICAR demonstrates a substantial and highly significant treatment effect in the advanced heart failure population, and no untoward effects attributable to MYDICAR are observed, a safety database of approximately 205-230 MYDICAR -treated subjects may be sufficient for a safety assessment to allow for acceptance of a Marketing Authorization Application, or MAA, for MYDICAR for the treatment of systolic heart failure. We therefore believe that, if the above conditions are met, a Phase 3 trial may not be required for marketing approval in Europe.

-- In November 2013, the long term follow-up results from the MYDICAR CUPID 1 Trial in advanced heart failure were presented by Dr. Barry Greenberg at the American Heart Association (AHA) annual meeting. The presentation included the following highlights:

• In the additional two year follow up period of the CUPID 1 trial, the durability of reduced cardiovascular and terminal events previously observed in the MYDICAR high dose cohort at 12 months was maintained. The risk of pre-specified recurrent cardiovascular events through the full three years of follow up was reduced by 82% in the high dose group compared to the placebo group (p=0.048).
• In addition, the survival probability over time was higher for patients in all MYDICAR dose groups compared to the placebo group, especially in the high dose group.
• Finally, persistence of the vector DNA as assessed by qPCR testing was demonstrated in three high dose MYDICAR patients in whom a biopsy was feasible, but not from patients in the placebo or lower dose groups.  Therefore, biomarker results correlated with the other beneficial effects observed in the high dose MYDICAR group.
• No safety concerns were noted during the three year follow-up period for patients who received MYDICAR.

-- In November 2013 at the American Society of Nephrology meeting, data on the role of SERCA2a deficiency in the blood vessels of dialysis patients experiencing AV fistula insertion were presented. SERCA2a was significantly decreased in the blood vessels of subjects undergoing dialysis versus subjects with normal renal function. In combination with other preclinical studies, these data support our plan to evaluate MYDICAR for improvement of AV fistula maturation failure in dialysis patients.

Small Molecule Program  

-- In February 2014, we entered into an option agreement with Les Laboratories Servier (Servier).  Under the terms of the agreement, we granted Servier an exclusive option to license the rights outside of the United States to our novel SERCA2b small molecule program in the field of diabetes and other metabolic disorders for a certain period. Servier's decision to exercise its option will be based upon the outcome of a series of pre-defined in vitro and in vivo studies to be performed by the parties.

-- In January 2013, the United States Patent and Trademark Office (USPTO) issued a notice of allowance for U.S. Patent Application No.: 13/145,787 with claims that cover methods for identifying compounds that modulate Sarco/Endoplamic Reticulum Calcium ATPase (SERCA) and methods for identifying compounds that modulate the SERCA/phospholamban complex using Celladon's proprietary fluorescence resonance energy transfer (FRET) assay. The patent term is expected to expire in 2030.

Recent Business Highlights

-- In February 2014, we successfully completed our initial public offering (IPO) of common stock, raising net proceeds of $44.3 million, inclusive of the over-allotment option exercised in full by the underwriters and after deducting offering expenses.

-- In March 2014, we appointed Peter K. Honig, M.D., M.P.H. and Dr. Patrick Y. Yang, Ph.D. to our Board of Directors. Dr. Honig currently serves as the Head of Global Regulatory Affairs at AstraZeneca, Inc. and Dr. Yang recently retired from F. Hoffman-La Roche AG, where he served as Global Head of Pharmaceutical Technical Operations.

Fourth Quarter and Year-End 2013 Financial Results

-- Cash Position: Cash, cash equivalents and investments as of December 31, 2013 were $18.4 million.

After giving effect to the net proceeds from the IPO, pro forma cash, cash equivalents and investments as of December 31, 2013 would have been $64.3 million.

About Celladon

Celladon is a clinical-stage biotechnology company applying its leadership position in the field of calcium dysregulation by targeting SERCA enzymes to develop novel therapies for diseases with tremendous unmet medical needs. Sarco/endoplasmic reticulum Ca2+-ATPase, or SERCA, enzymes 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, which is a clinical syndrome characterized by poor heart function, resulting in inadequate blood flow to meet the body's metabolic needs, as well as diabetes and neurodegenerative diseases. Celladon's therapeutic portfolio for diseases characterized by SERCA enzyme deficiency includes both gene therapies and small molecule compounds. MYDICAR, the Company's most advanced product candidate, uses gene therapy to target SERCA2a, which is an enzyme that becomes deficient in patients with heart failure.  In addition, Celladon has 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.
