Ra Medical Systems Announces Progress with Guidewire-Compatible Catheter Design and Provides Update on Atherectomy Trial Enrollment
CARLSBAD, Calif.--(BUSINESS WIRE)-- Ra Medical Systems, Inc. (NYSE American: RMED), a medical device company focused on commercializing excimer laser systems to treat vascular and dermatological diseases, announces progress with finalizing the next-generation guidewire-compatible DABRA catheter design following a recent two-day, hands-on workshop with interventionalists who evaluated prototypes of the next-generation excimer laser catheter. DABRA is the company’s minimally invasive excimer laser system for the treatment of vascular blockages resulting from lower extremity vascular disease, a form of peripheral artery disease, or PAD.
The company also announces that enrollment in its pivotal atherectomy clinical trial with the DABRA excimer laser system is now at 62 subjects, including 42 subjects enrolled since the beginning of 2021. This trial is expected to enroll up to 100 subjects.
“I’m delighted Ra Medical Systems has made such significant forward progress in bringing a guidewire-compatible platform of their next-generation catheter to the market, while also advancing towards regulatory clearance for the atherectomy indication,” said Tom Davis, MD, an interventional cardiologist practicing at Eastlake Cardiovascular, P.C. “Achievement on both these milestones are critical and positive steps toward their commercialization success and represents a promising technology for expanded patient care options in my practice.”
“We are grateful for the valuable feedback we have received from our physician advisors as they are leaders in their field and represent the customer base for our excimer laser system,” said Will McGuire, Ra Medical Systems CEO. “Also, the current pace of enrollment in our atherectomy trial is encouraging, as we believe regulatory clearance for this indication will better position Ra Medical to address the large and growing market for treating vascular disease.”
About the DABRA Excimer Laser System
The DABRA excimer laser system received U.S. FDA 510(k) clearance in May 2017 for crossing chronic total occlusions, or CTOs, in patients with symptomatic infrainguinal lower extremity vascular disease with an intended use for ablating a channel in occlusive peripheral vascular disease. The FDA defines atherectomy to include a prespecified improvement in luminal patency. Third-party research estimates the value of the combined CTO and atherectomy markets in the U.S. at approximately $900 million for 2021, with atherectomy representing more than $750 million.
The open-label pivotal atherectomy clinical trial can enroll up to 100 subjects with symptoms of peripheral arterial disease (Rutherford Class 2-5) at up to 10 U.S. sites. Outcome measures include safety, acute technical success and clinical success. The trial’s primary efficacy endpoint is the mean reduction in percent diameter stenosis in each patient’s primary lesion as measured by angiography immediately following treatment with DABRA and before any adjunctive treatment. The trial’s safety and clinical success endpoints are major adverse events at 30 days post-procedure and incidence of primary target lesion revascularization at six months post-procedure.
