SANTA CLARA, Calif., Nov. 07, 2019 (GLOBE NEWSWIRE) -- Shockwave Medical, Inc. (NASDAQ: SWAV), a pioneer in the development of Intravascular Lithotripsy (IVL) to treat complex calcified cardiovascular disease, announced today that the company has initiated the DISRUPT CAD IV study of IVL in heavily calcified coronary arteries that is intended to support regulatory device approval in Japan.
The first CAD IV patient was enrolled earlier this week by the principal investigator of the study, Shigeru Saito, M.D., Director of Cardiology and Catheterization Laboratories and Vice President, Shonan Kamakura General Hospital. DISRUPT CAD IV is a prospective, multicenter, single-arm study to demonstrate the safety and effectiveness of the Shockwave Coronary IVL System with the Shockwave C2 IVL Catheter in the treatment of de novo, calcified, stenotic, coronary arteries prior to stenting. The study is expected to enroll up to 64 patients at 8 sites in Japan.
“We are honored to initiate the clinical investigation of coronary IVL in Japan to evaluate calcium modification,” said Dr. Saito. “From the European results and our initial experience with the technology, IVL therapy has the potential to change the way we treat calcified lesions for the future benefit of patients.”
Similar to the DISRUPT CAD III Study protocol, CAD IV will assess the absence of major adverse cardiac events (MACE) within 30 days of the index procedure as the primary safety endpoint. The primary effectiveness endpoint is procedural success, defined as stent delivery with a residual stenosis <50 percent, and without in-hospital MACE. Study enrollment is expected to be completed by June 2020, from which enrolled patients will be followed for two years.
“Based on the interest, feedback and rapid adoption in other Asia Pacific countries where we have introduced coronary IVL, we are excited for the prospect of providing Japanese physicians with access to this therapy for the first time,” said Doug Godshall, President and Chief Executive Officer of Shockwave Medical. “Japan holds tremendous potential for IVL, and we look forward to completing the study and working with the regulators so that Japanese patients and their providers will be able to access IVL therapy as soon as possible.”
Coronary artery calcium physically impairs stent expansioni and is perhaps the single most important predictor of early stent thrombosis and restenosis after stent procedures.ii, iii, iv Coronary IVL is a therapy designed to treat calcified artery blockages with sonic pressure waves historically used to treat patients with kidney stones. The technology seeks to minimize trauma within the artery by delivering pulsatile sonic pressure waves locally to fracture both intimal and medial calcium in the artery wall but pass through surrounding soft vascular tissue in a safe manner.
Shockwave C2 Coronary IVL catheters are commercially available for the treatment of de novo coronary artery disease in Europe and other select countries; in Japan they are limited to investigational use within the DISRUPT CAD IV Study. In the United States they are limited to investigational use within the DISRUPT CAD III Study.
