All 20 patients underwent successful CarpX procedures while passing primary effectiveness endpoint, with all follow-up patients to date passing primary safety endpoint
NEW YORK, Aug. 15, 2019 (GLOBE NEWSWIRE) -- PAVmed Inc. (Nasdaq: PAVM, PAVMZ) (the "Company" or "PAVmed"), a highly differentiated, multiproduct medical device company, today announced that all 20 patients of its first-in-human (FIH) 510(k) clinical safety study underwent successful CarpX procedures. The study is being conducted to support PAVmed's planned 510(k) re-submission to the U.S. Food and Drug Administration (FDA) seeking marketing clearance of its CarpX minimally invasive carpal tunnel release device.
"We are excited to have achieved this critical milestone," said Lishan Aklog, M.D., PAVmed's Chairman and Chief Executive Officer. "Our success with this study brings us one step closer to fulfilling our mission to transform how carpal tunnel syndrome is treated for millions of people worldwide, representing a billion-dollar market opportunity in the U.S. alone."
"CarpX performed flawlessly as a precision cutting device in these 20 consecutive patients. Using CarpX, surgeons were able to replicate the outstanding results of our pre-clinical testing and achieve the same anatomic results as traditional open surgery - complete and precise cutting of the transverse carpal ligament - using a minimally invasive approach."
Brian J. deGuzman, M.D., PAVmed's Chief Medical Officer, who trained the surgeons and was present in the operating room during all of the procedures, noted other positive observations from the study, which included:
- The final set of procedures were completed in 15-20 minutes "skin-to-skin", suggesting after only a short learning curve the CarpX procedure can be performed in the same or less time as traditional carpal tunnel release.
- As they gained experience with the CarpX procedure during the study, the surgeons were able to use progressively smaller incisions. The final set of procedures were performed through the smallest keyhole incisions that would pass the introducer sheath, approximately 5-10 mm each, with no incision crossing the base of the palm, the problematic area for healing, recovery and persistent pain after traditional surgery.
- CarpX's balloon appeared to create more space within the carpal tunnel at completion of the procedure compared to traditional surgery. This unique feature of CarpX has the potential to enhance both short and long-term outcomes.
- CarpX required less power and lower balloon pressures to cut the scarred ligament in live human patients than it had previously demonstrated in cadavers, an unexpected positive finding which should further enhance the procedure.
- Most importantly, initial patient feedback has been positive, including one patient who noted his recovery was much faster than a friend who had a "mini-open" carpal tunnel release and insisted the procedure on his other hand be performed with CarpX.
The procedures were performed at St. George's Hospital in Christchurch, New Zealand, with patients completing preoperative testing in accordance with the study protocol developed in collaboration with the FDA. All 20 patients underwent successful minimally invasive carpal tunnel release using the CarpX device and passed the protocol's primary effectiveness endpoint - intraoperative confirmation of complete division of the transverse carpal ligament by endoscopic visualization of its cut edges across its entire width. There were no device-related adverse events.
As per the protocol, patients are undergoing post-operative clinical follow-up at two weeks and 90 days. All of the patients who have completed their follow-up have passed the study's specified primary safety endpoint and, based on clinical observations, it is expected that all of the remaining patients will as well. PAVmed will resubmit the CarpX 510(k) application incorporating the clinical safety and effectiveness data from the study once 90-day follow-up is completed in all 20 patients.
CarpX is a minimally invasive device developed to treat carpal tunnel syndrome while reducing recovery times. 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.
PAVmed Inc. is a highly differentiated, multiproduct medical device company employing a unique business model designed to advance innovative products to commercialization much more rapidly and with significantly less capital than the typical medical device company.
