상세 설명
The American Heart Association (AHA) 2006 update on heart disease reported that 5 million Americans are believed to have symptomatic heart failure (HF), and 550,000 patients are newly diagnosed each year. The estimated direct and indirect cost of HF in the United States (U.S.) for 2006 will be ~$29.6 billion. Heart failure is a disabling chronic disease and the most frequent discharge diagnosis for hospitalization among older adults. Despite the significant resources expended on the treatment of this disease, outcomes remain poor. The five-year survival for individuals diagnosed with heart failure is less than 50%, and in end-stage heart failure, the one-year survival may be as low as 25% regardless of medical therapy.
Recent studies suggest that the failing heart is not refractory to treatment, as was previously believed. For example, the observation that a small percentage of subjects with left ventricular assist devices (LVADs) can be permanently weaned from their device strongly suggests that damaged hearts are capable of recovering lost function.
Clinical studies of MYDICAR® have not yet been conducted in humans. Celladon Corporation (Celladon) proposes to investigate gene transfer as a method to restore SERCA2a function in heart failure (HF) patients using a recombinant adeno-associated viral vector (AAV), which consists of an AAV serotype 1 capsid and contains the human SERCA2a complementary DNA (cDNA) flanked by Inverted Terminal Repeats (ITR) derived from AAV serotype 2 (AAV1/SERCA2a). MYDICAR® refers to AAV1/SERCA2a drug product intended for administration by percutaneous delivery.

Phase 2: Change in Symptomatic Efficacy Domains From Baseline to Month 6: New York Heart Association (NYHA) Class and Minnesota Living With Heart Failure Questionnaire (MLWHFQ) Score
기간: Baseline to 6 months
|
NYHA classification is a symptomatic assessment in which the investigator evaluates subjects on a scale ranging from Class I (subjects with no limitation of activities, no symptoms from ordinary activities) to Class IV (subjects who should be at complete rest, confined to bed or chair; any physical activity brings on discomfort and symptoms occur at rest). The MLWHFQ is a patient-reported quality of life (QoL) measure in which patients assess the impact of their heart condition on activities in the past month using a Likert scale ranging from 0 (no effect) to 5 (very much effect). Higher scores thus indicate a lower QoL. The maximum (worst) score is 105 and the minimum (best) score is 0. For both measures, changes from baseline with positive values indicate a worsening in symptoms and changes from baseline with negative values indicate an improvement in symptoms. |

|
Phase 2: Change in 6-minute Walk Test (6MWT) From Baseline to Month 6
기간: Baseline to 6 months
|
The 6MWT measures the distance walked in meters during a 6-minute test.
Higher values indicate a better functional status.
Changes from baseline with negative values indicate a worsening in function and changes from baseline with positive values indicate an improvement in function.

|
|
Phase 2: Change in Peak Maximum Oxygen Consumption (VO2) From Baseline to Month 6
기간: Baseline to 6 months
|
Peak VO2 is a measure of maximal oxygen consumption during cardiopulmonary exercise testing; this study used the modified Naughton treadmill protocol.
Higher values indicate a better functional status.
Changes from baseline with negative values indicate a worsening in function and changes from baseline with positive values indicate an improvement in function.

|
|
Phase 2: Change in Absolute Levels of N-terminal Prohormone Brain Natriuretic Peptide (NT-proBNP) From Baseline to Month 6
기간: Baseline to 6 months
|
NT-proBNP is a biomarker for heart failure.
Increased levels of this biomarker are associated with increased mortality and cardiovascular hospitalization in patients with heart failure.
|

|
|
Phase 2: Change in Percentage of Blood Ejected From the Left Ventricle (LV) (i.e., Left Ventricular Ejection Fraction [LVEF]) From Baseline to Month 6

Contrast echocardiography was used to determine LVEF.
Increases in LVEF are associated with reduced mortality.
Changes from baseline with positive values indicate an improvement in heart function and changes from baseline with negative values indicate a worsening of heart function.

Phase 1 and Phase 2: All Subject Deaths Through 36 Months
기간: 36 months
|
All subject deaths that occurred during the 12-month study or the 24-month follow-up in subjects enrolled in either the Phase 1 or Phase 2 trial.
Events occurring after early termination from the trial are listed as occurring during long-term follow-up, but may have been within 12 months.
Specifically, two cardiovascular (CV) deaths in placebo subjects occurred following early study termination, but within 12 months of study initiation.
These deaths are therefore included under "Deaths within 12 months" but also listed as "Cardiovascular deaths in long-term follow-up."
Accordingly, the number of "Cardiovascular deaths in long-term follow-up" for the placebo group is greater than the number of "Deaths after 12 months," as 2 of the deaths occurred within 12 months but after early termination.
