HeartWare receives FDA approval to enroll supplemental patient cohort
The FDA has approved an IDE Supplement for HeartWare International, an innovator of less invasive, miniaturized circulatory support technologies for the treatment of advanced heart failure, to commence enrollment in an additional patient cohort for ENDURANCE, the company's Destination Therapy clinical study.
HeartWare will enroll up to 286 patients receiving the HeartWare Ventricular Assist System, and up to an additional 143 control patients using a randomization scheme consistent with the ENDURANCE protocol. Patients will be followed for 12 months after implant. HeartWare intends to incorporate the data from both this new cohort and ENDURANCE into an anticipated Pre-Market Approval (PMA) Application seeking approval of the HeartWare System for the Destination Therapy indication.
The protocol for this cohort is designed to confirm clinical observations that sites adhering to more regular monitoring and management of patient blood pressure witnessed a notably lower incidence of neurological events.
Patient enrollment will commence at the 50 centers participating in the ENDURANCE clinical trial, following Institutional Review Board approvals at each of the centers.
In Nov. 2012, FDA granted approval of the HeartWare System for the Bridge-to-Transplant indication. Concurrent with approval, the company commenced a post-approval study (PAS) to assess device performance in a real-world setting. HeartWare's PAS is a registry consisting of 600 patients who receive an HVAD and an additional 600 control patients derived from a contemporaneous group of continuous flow, intra-corporeal LVAD patients entered into the INTERMACS database. HeartWare expects enrollment for both arms of the PAS will be complete by year's end.
