Boston Scientific Corporation has announced a definitive agreement to acquire Apama Medical, a privately-held company that is developing the Apama Radiofrequency (RF) Balloon Catheter System for the treatment of atrial fibrillation (AF). The transaction consists of US$175 million in cash up-front and a maximum of US$125 million in contingent payments over the period of 2018–2020 based on achievements of clinical and regulatory milestones.
The standard of care in AF ablations is pulmonary vein isolation (PVI)—the application of energy to create lines of scar tissue around the pulmonary veins in the left atrium to block unwanted electrical signals that trigger AF. PVI is currently performed using two different technologies: point-by-point RF-based ablation and single-shot balloon-based ablation.
The Apama RF balloon—a single-shot, multi-electrode technology—is designed to combine the primary benefits of both RF point-by-point and balloon-based ablation approaches, notably the ability to deliver differentiated levels of energy and shortened procedure times. The technology incorporates built-in digital cameras with LED lights and sensing electrodes on the balloon which allow for real-time visualisation and assessment of catheter electrode contact. This is intended to provide physicians with higher confidence of effective energy delivery and the ability to customise the amount of energy delivered around the circumference of the balloon, while further reducing procedure times when compared to existing balloon technologies.
“The acquisition of Apama further advances our continued investment in the electrophysiology category, and, upon commercialisation, would broaden our portfolio of differentiated arrhythmia solutions,” says Joe Fitzgerald, president of Rhythm Management, Boston Scientific. “We are also excited about the ability to integrate the Apama RF balloon system with our RHYTHMIA HDx Mapping System to provide physicians with an unprecedented visualization of the heart during ablation procedures.”
Initial results of AF-FICIENT, a first-in human study presented at the AF Symposium Annual Meeting (12–14 January, Orlando, USA), demonstrated the Apama RF balloon met the safety and efficacy study endpoints, achieving successful PVI in patients with paroxysmal AF.
“Study results reinforce the Apama RF balloon is an advancement in single-shot technology for PVI and can provide physicians with greater control and efficiency when performing AF ablations,” said Kenneth Stein, senior vice president and chief medical officer, Rhythm Management and Global Health Policy, Boston Scientific. “We look forward to continuing the development and commercialisation of this novel ablation solution to treat both paroxysmal and persistent AF.”
The Apama RF balloon is currently being studied in clinical trials in Europe to serve as the basis for CE mark approval, which is expected in late 2018.
Apama is based in Campbell, California, with approximately 40 employees.
The acquisition is projected to close during the fourth quarter of 2017, subject to customary closing conditions.
On an adjusted basis, the transaction is expected to be immaterial to Boston Scientific adjusted earnings per share for 2017 and 2018. The transition is expected to be more dilutive on a GAAP basis, due to amortisation expense, transaction, and integration related costs.
The Apama RF Balloon Catheter System is a concept device and not available for sale.
