Researchers' Work from Cardiovascular Research Center Focuses on Gene Therapy

June 26, 2014



By a News Reporter-Staff News Editor at Gene Therapy Weekly -- Current study results on Biotechnology have been published. According to news originating from New York City, New York, by NewsRx correspondents, research stated, "The Calcium Up-Regulation by Percutaneous Administration of Gene Therapy In Cardiac Disease (CUPID 1) study was a phase 1/phase 2 first-in-human clinical gene therapy trial using an adeno-associated virus serotype 1 (AAV1) vector carrying the sarcoplasmic reticulum calcium ATPase gene (AAV1/SERCA2a) in patients with advanced heart failure. The study explored potential benefits of the therapy at 12 months, and results were previously reported."

Our news journalists obtained a quote from the research from Cardiovascular Research Center, "To report long-term (3-year) clinical effects and transgene expression in the patients in CUPID 1. A total of 39 patients with advanced heart failure who were on stable, optimal heart failure therapy were randomized to receive intracoronary infusion of AAV1/SERCA2a in 1 of 3 doses (low-dose, 6x10(11) DNase-resistant particles; mid-dose, 3x10(12) DNase-resistant particles; and high-dose, 1x10(13) DNase-resistant particles) versus placebo. The following recurrent cardiovascular and terminal events were tracked for 3 years in all groups: myocardial infarction, worsening heart failure, heart failure-related hospitalization, ventricular assist device placement, cardiac transplantation, and death. The number of cardiovascular events, including death, was highest in the placebo group, high but delayed in the low- and mid-dose groups, and lowest in the high-dose group. Evidence of long-term transgene presence was also observed in high-dose patients. The risk of prespecified recurrent cardiovascular events was reduced by 82% in the high-dose versus placebo group (P=0.048). No safety concerns were noted during the 3-year follow-up."

According to the news editors, the research concluded: "After a single intracoronary infusion of AAV1/SERCA2a in patients with advanced heart failure, positive signals of cardiovascular events persist for years."
