Veranex Announces Investment From Summit Partners to Form Comprehensive Concept-to-Commercialization Medtech Services Company

As the first phase in building this global entity, Veranex has acquired three complementary solution providers: Ximedica, Quartesian, and Boston Healthcare Associates. By bringing these companies together, Veranex combines the industry’s key pillars of design and engineering, regulatory, clinical, and market access into a single-source solution.

Abiomed (NASDAQ:ABMD), a leading provider of breakthrough heart support technologies and the maker of the Impella RP heart pump, announces that survival data from the 18 month post-approval study of 42 Impella RP patients was presented at the American College of Cardiology’s (ACC) 68th Annual Scientific Session in New Orleans.

The Impella RP is the only percutaneous technology with FDA PMA approval for right heart support designated safe and effective. The table below summarizes the new post-approval study data and compares it to the FDA study results submitted for Impella RP’s PMA approval.

The post-approval study data was reviewed and submitted to the FDA by Abiomed on Wednesday, March 13, 2019. The FDA has confirmed the classification of patients into two categories: Recover Right protocol and salvage support. The Recover Right protocol includes patients who met the inclusion and exclusion criteria of the Recover Right FDA PMA clinical trial for Impella RP. The FDA also recognizes salvage patients as those outside the Recover Right protocol (>48 hours in cardiogenic shock from right side failure.)

The baseline characteristics of the two populations were different with higher mortality in the salvage group. Salvage patients are some of the sickest patients in the hospital and many have suffered out-of-hospital cardiac arrest or may have been transferred to multiple hospitals before receiving Impella RP. The FDA and Abiomed believe that physicians should have the ability to attempt lifesaving recovery measures on these patients based on their best judgement. Tim Deits, a 16-year-old Impella RP patient from Huntington Beach, Calif., is an example of an extremely sick patient who experienced an unwitnessed out-of-hospital cardiac arrest event, received CPR, and survived with recovery of his native heart.

The Impella RP post-approval study data compares to a survival rate of 73% in the Impella RP PMA Study, 42% for surgically implanted CentriMag RVAS HDE study protocol, and 29% – 42% self-reported survival to transfer or discharge for adult cardiac ECMO patients1. To note, the Recover Right protocol matches the CentriMag surgical protocol defined by the FDA as right-side failure. The Impella RP is the only device submitting post-approval study data on real-world patient outcomes, including salvage utilization. This patient population will continue to be studied in the ongoing cVAD Study.

“When a patient is in right heart failure, Impella RP allows the heart to rest and recovers the heart’s ability to pump blood,” said David Wohns, MD, Chief of Cardiology at Spectrum Health. “The Impella RP is an effective treatment for patients who receive a timely implant and meet the Recover Right inclusion and exclusion criteria.”

“The post-approval study data is analogous to our own independent data from multiple hospitals in the Cardiogenic Shock Working Group, which found an approximate 80% survival rate when the Impella RP was used in cardiogenic shock patients who met inclusion criteria from the Recover Right Study,” said Navin Kapur, MD, Executive Director of the CardioVascular Center for Research and Innovation at Tufts Medical Center. “Data like these highlight how the use of algorithms to recognize right sided failure and protocols for early hemodynamic support can help improve outcomes for cardiogenic shock patients.”

Abiomed encourages clinicians to review proper inclusion and exclusion criteria for Impella RP and to follow guidelines, which recommend implantation of Impella RP within 48 hours of cardiogenic shock onset caused by right side failure. Abiomed also encourages the use of best practices such as the National Cardiogenic Shock Initiative and the Shock Care Pathway Algorithms. Abiomed is committed to improving outcomes by leading in data collection within our commercial IQ Database and cVAD post-approval studies in order to identify and validate best practices.
