• 35-subject SWING Trial evaluates the safety, performance of Surmodics’ Sundance™ Sirolimus Drug-Coated Balloon
• Differentiated capabilities of Surmodics’ crystalline drug release platform to be discussed in connection with SWING trial 12-month data

Surmodics, Inc. (NASDAQ:SRDX), a leading provider of medical device and in vitro diagnostic technologies to the health care industry, announced today that Professor Ramon Varcoe will present 12-month data from the SWING Trial, a first-in-human study of the safety and performance of the Sundance™ Sirolimus Drug-Coated Balloon (DCB). The session will be held on Wednesday, January 18, at the 35^th annual International Symposium on Endovascular Therapy (ISET) conference in Miami, Florida. Professor Varcoe will also discuss the differentiated capabilities of the Surmodics crystalline drug release platform for sirolimus-coated balloons (SCBs) in connection with 12-month data from the SWING trial.

Professor Varcoe, MBBS, MS, FRACS, PHD, MMed (ClinEpi), co-lead investigator of the SWING Trial, is a vascular surgeon at Sydney’s Prince of Wales and Prince of Wales Hospital where he is Director of Operating Theatres, and Director of Surgery and Anesthetics for the South East Sydney Health District. He will review safety and performance data collected through 12 months of follow-up for 35 subjects with occlusive disease of the infra-popliteal arteries who were treated at study sites in Australia, New Zealand, and locations in Europe. Study subjects will be followed for 36 months after the index procedure. Professor Andrew Holden, MBChB, FRANZCR, EBIR, ONZM, Director of Northern Region Interventional Radiology Service at Auckland City Hospital in Auckland, New Zealand, is also a co-lead investigator for the SWING Trial.

Professor Varcoe recently presented SWING Trial 12-month data on Nov. 16 at the 49th Annual Symposium on Vascular and Endovascular Issues (VEITHsymposium).

The Sundance Sirolimus Drug-Coated Balloon utilizes a next-generation coating technology consisting of microcrystalline sirolimus and a proprietary excipient designed to maximize drug transfer, enhancing sirolimus delivery and sustaining therapeutic levels in the artery. Sirolimus, a potent anti-inflammatory and anti-proliferative compound, has been used successfully in coronary drug-eluting stents. The delivery of sirolimus to the vessel wall during mechanical balloon dilatation provides an ancillary action of inhibiting the proliferation of cells, with the intended purpose of reducing restenosis. The Sundance Sirolimus Drug-Coated Balloon is not available for sale anywhere in the world, and currently is for investigational use only.
