PAVmed Announces FDA 510(k) Re-submission for its CarpX™ Minimally Invasive Carpal Tunnel Device


Incorporates data from successful clinical safety study in which all patients met pre-specified safety and effectiveness endpoints

NEW YORK, March 09, 2020 (GLOBE NEWSWIRE) -- PAVmed Inc. (Nasdaq: PAVM, PAVMZ) (the “Company” or “PAVmed”), a highly differentiated, multiproduct medical device company, today announced the U.S. Food and Drug Administration (FDA) has acknowledged receipt of a 510(k) premarket notification submission for the Company’s CarpX™ minimally invasive carpal tunnel device. This re-submission incorporates data from the Company’s successful first-in-human CarpX clinical safety study, in which all patients met the study’s pre-specified safety and effectiveness endpoints.

“We look forward to completing the U.S. regulatory process for CarpX so we can begin offering this groundbreaking technology for alleviating carpal tunnel syndrome to physicians and their patients,” said Lishan Aklog, M.D., PAVmed’s Chairman and Chief Executive Officer. “We believe the data in this 510(k) re-submission demonstrate the safety and effectiveness of CarpX as well as its substantial equivalence to the predicate device. As expected, our clinical safety study found CarpX to be a precision cutting device, consistent with its design and the results of extensive pre-clinical testing, meeting both pre-specified safety and effectiveness endpoints, with no device-related adverse events. Based on these results, we believe CarpX has the potential to transform carpal tunnel syndrome treatment by dramatically reducing recovery times compared to traditional open surgery, an estimated billion-dollar U.S. market opportunity.”

PAVmed is seeking FDA 510(k) clearance to market CarpX for minimally invasive carpal tunnel release. Extensive pre-clinical testing, performed under close FDA consultation, demonstrated that CarpX was safe, effective and substantially equivalent to the selected predicate. This testing specifically documented a very precise thermal profile, with negligible thermal energy spread beyond the target tissue cut line, as recommended by the FDA.

The FDA subsequently recommended a clinical safety study to support 510(k) re-submission. The Company consulted closely with the FDA during development of the study protocol, which it then utilized in its recently completed CarpX first-in-human clinical safety study. Twenty carpal tunnel syndrome patients in New Zealand underwent successful CarpX minimally invasive carpal tunnel release. All patients met the study’s pre-specified effectiveness endpoint – clinical device technical success defined as the ability of CarpX to perform complete division of the transverse carpal ligament (TCL) as assessed by post-procedural endoscopic inspection of the TCL after treatment. Two-week and 90-day post-operative follow-up rates were 100% and 95%, respectively, exceeding the target 80% rate recommended by the FDA. The only loss to follow-up was a patient who was documented to be “back to normal” with resolution of symptoms at six weeks, but opted not to return to the study site because he was traveling a significant distance away and was overall very satisfied with the procedure’s outcome.

All patients who completed follow-up met the study’s pre-specified primary safety endpoint – device safety defined as no serious adverse event probably or definitely related to the device resulting in significant morbidity through 90-day follow-up. Patients underwent additional pre-specified outcome assessments at baseline and during post-operative follow-up, using well-established, standardized and validated measures to assess patient satisfaction, as well as changes in symptoms, motor and sensory function and neurophysiological parameters following carpal tunnel release. These outcome assessments included the Global Satisfaction Questionnaire, QuickDASH and Boston Carpal Tunnel Syndrome (BCTQ) Questionnaires, Ten Test and Semmes-Weinstein Monofilament sensory tests, Grip and Pinch Strength motor function tests, as well as nerve conduction and electromyographic studies. The excellent results of these pre-specified outcome assessments following CarpX minimally invasive carpal tunnel release were similar to, or better than, expected results following traditional open surgery.

Additional observations from the study strongly support CarpX’s clinical and commercial potential. Surgeons were able to achieve the same anatomic result as traditional open surgery using a minimally invasive approach. Endoscopic visualization showed that CarpX cut the ligament cleanly and precisely, without evidence of thermal spread beyond the target tissue cut line. Procedure times fell after a short learning curve, indicating that CarpX minimally invasive carpal tunnel release can be performed in the same or less time as traditional open surgery. The final set of procedures were performed through 5-10 mm keyhole incisions, with no incision crossing the base of the palm, an area known to be problematic for healing, resulting in delayed recovery and persistent pain after traditional open surgery. The surgeons also observed that the CarpX balloon appeared to create more space within the carpal tunnel than traditional carpal tunnel release, which could favorably impact long-term outcomes.

About CarpX

CarpX is a patented single-use disposable minimally invasive device designed to treat carpal tunnel syndrome while reducing recovery times. PAVmed believes CarpX will dramatically reduce recovery times compared to traditional open surgery while targeting an estimated $1 billion immediately addressable domestic market opportunity. CarpX is designed to closely mimic the anatomic results of invasive carpal tunnel surgery, but much less invasively, using catheters, balloons, radiofrequency energy and other established tools that have contributed to percutaneous and minimally invasive revolutions in the treatment of other conditions. The balloon catheter device is designed to be inserted under the scarred ligament in a minimally invasive fashion, while pushing the nerve and tendons away. When activated, bipolar radiofrequency electrodes precisely cut the ligament from the inside out in a matter of seconds. The device design provides physicians with ongoing feedback to optimize the safety and completeness of the procedure.
