NEW YORK, Feb. 27, 2012 /PRNewswire/ -- JARVIK HEART, Inc., a privately-held company that develops and manufactures cardiac assist devices, announced conditional FDA approval of its Pivotal Trial for evaluation of the Jarvik 2000® heart for destination therapy (DT). Use of the device for DT means that it will provide long-term, permanent support to end-stage congestive heart failure patients who are not candidates for heart transplant. The approval permits fifty medical centers to participate in the study. Each medical center may begin enrolling patients immediately upon approval by their Institutional Review Board.

Prior to full FDA approval of the trial, the company must submit additional information concerning statistical analysis and conduct of the study, as well as some additional engineering data.
The trial will randomize up to 350 study subjects to either the treatment group, in which patients receive the Jarvik 2000 intraventricular heart assist device, or the control group, in which patients receive the HeartMate® II left ventricular assist device (LVAD), the most widely used FDA-approved LVAD for DT. Patients will be followed for two years to assess primary endpoint success, generally defined as survival free of disabling complications. If the data analysis at two years, or at a prior interim analysis, establishes non-inferiority of the Jarvik 2000 compared to the control, the trial will be judged successful. Additionally, the patients will be followed for another year and the rates of serious infection related to the power cable and pump pocket will be analyzed for the three years since implant. Regarding device-related infection, the analysis is designed to determine if the Jarvik 2000 that uses a unique behind-the-ear power cable and has no pump pocket is superior to the HeartMate II, which uses an abdominal cable and has an abdominal pump pocket.
The Jarvik 2000 has been used to treat late-stage heart failure in more than 500 patients in the United States, Europe, and Asia. The Jarvik 2000 model with the behind-the-ear connector has supported more than 200 patients in Europe for DT, including the longest survival of any heart assist device patient in the world, 7 1/2 years.
The bridge-to-transplant model of the Jarvik 2000 has a power cable that exits the abdominal wall—the same position used with the HeartMate II and HeartWare® VADs. The behind-the-ear cable, which will be used in this study, may have significant quality-of-life advantages over abdominal cables. It requires practically no care of the cable exit site and, unlike abdominal cables, does not require frequent redressing with sterile bandages that may require expensive home nursing. Jarvik 2000 patients with the behind-the-ear connector may shower and bathe normally and can even go swimming. In Europe, these patients have had low rates of infection, and there have been no failures of the internal cables and no mechanical failures of the Jarvik 2000 blood pump or its bearings. Long-term bench durability tests project high reliability of the device for ten years or more.
JARVIK HEART has also completed enrollment of the primary cohort of 150 patients in the US Bridge-to-Transplant Pivotal Study and is nearing completion of the follow-up period. Only two patients have yet to reach outcome. The results in the study patients who received the most recent Jarvik 2000 model, using patented cone bearings, are expected to show a substantial improvement in the primary endpoint compared to the pin bearing design used earlier in the BTT study. Only cone bearings will be used in the DT trial.
JARVIK HEART is continuing research on new developments including child size and tiny infant size pumps with the support of the National Institutes of Health under the “PumpKIN” program (Pumps for Kids, Infants, and Neonates).
Additionally, JARVIK HEART is developing other new innovative cardiac assist devices intended to enhance patient quality of life.
