Endologix Announces Completion of Enrollment in the TORUS 2 Study for PAD in SFA

The TORUS 2 study is a prospective, single-arm trial of 188 patients to evaluate safety and effectiveness of the TORUS Stent Graft System. in the treatment of PAD in the SFA and proximal popliteal arteries.

IRVINE, Calif. November 23, 2021—Endologix LLC, a privately held global medical device company dedicated to improving patients’ lives by providing innovative therapies for the interventional treatment of vascular disease, completed enrollment in the TORUS 2 IDE clinical study (NCT04130737) in the United States.  The study was designed to evaluate safety and effectiveness of the TORUS Stent Graft System in the treatment of obstructive atherosclerotic lesions of the native SFA and proximal popliteal arteries.

The study is led by national co-principal investigators Peter Schneider M.D., Professor of Surgery, Division of Vascular and Endovascular Surgery at University of California San Francisco, and Ehrin Armstrong M.D., MSc, FACC, FSCAI, FSVM, Medical Director, Adventist Heart and Vascular Institute at Adventist Health St. Helena.  “The development of a new self-expanding covered stent for treatment of the SFA and proximal popliteal arteries represents an important advancement in optimal endovascular therapy of complex lesions,” said Ehrin Armstrong, MD.

“We especially appreciate the strong efforts of our clinical trial sites to enroll this trial efficiently and with high quality. This is the first time in years that a new and specifically designed stent graft for the femoral-popliteal segment is being evaluated for clinical utility,” said Peter Schneider, MD.

“The completion of enrollment for TORUS 2 is a significant milestone in a clinically-challenging area of vascular disease,” said Matt Thompson, MD, President and CEO of Endologix.  “The TORUS stent-graft is also a pivotal component of the DETOUR procedure, a totally percutaneous femoropopliteal bypass, currently under clinical investigation. Both systems continue our commitment to expanding the Endologix portfolio of innovative devices and supporting clinical evidence.”
