Simultaneous Publication of Three Studies in the Journal of the American College of Cardiology: Cardiovascular Interventions
SANTA CLARA, Calif., June 28, 2021 (GLOBE NEWSWIRE) — Shockwave Medical, Inc. (NASDAQ: SWAV), a pioneer in the development of Intravascular Lithotripsy (IVL) to treat severely calcified cardiovascular disease, announced today that the safety, efficacy and mechanism of benefit of IVL for the treatment of coronary and peripheral artery disease has been further elucidated with the publication of three separate manuscripts in the June 28, 2021 issue of the Journal of the American College of Cardiology: Cardiovascular Interventions (JACC CI), comprising a pooled analysis of four studies involving coronary IVL, a randomized clinical trial involving peripheral IVL and a Mechanism of Action paper. A summary of each published article is outlined below.
The patient-level pooled analysis of the four prospective Disrupt CAD studies (Disrupt CAD I, II, III, and IV) analyzed the clinical outcomes of coronary IVL in severely calcified, stenotic de novo coronary arteries prior to stenting. The analysis reports the largest cohort of patients (628) treated with coronary IVL to date. The key findings include:
As noted in the accompanying editorial, the key limitation is that the studies do not include a head-to-head control group. The Disrupt CAD studies were designed to obtain regulatory approval for Shockwave C2 Coronary IVL device in the European Union, United States and Japan.
Disrupt PAD III is the largest-ever randomized controlled trial (RCT) assessing the treatment of calcified lower extremity arterial lesions. It compares vessel preparation with peripheral IVL to percutaneous transluminal angioplasty (PTA) in patients receiving drug-coated balloon (DCB) treatment for peripheral arterial disease (PAD). Below are the key findings:
The study authors conclude that IVL treatment required significantly less bail-out stenting to achieve a successful outcome, thereby facilitating a “leave-nothing-behind” approach in patients with severely calcified lower extremity arterial lesions. As was noted in the accompanying editorial, the objective of the study was to determine if IVL was able to prepare the vessel with a low residual stenosis and without severe dissections or the need for stents versus more narrowly focusing on only the residual stenosis at the end of the procedure.
The IVL Mechanism of Action state-of-the-art review presents principles of lithotripsy therapy including the IVL system, procedure, energy distribution, and specific mechanisms for calcium modification. Key findings include:
“It is a tremendous accomplishment to have three separate publications in such a well-respected journal like JACC CI,” said Dean Kereiakes, M.D., FACC, FSCAI, President of The Christ Hospital Heart and Vascular Institute, Professor of Clinical Medicine, The Ohio State University and Principal Investigator for Disrupt CAD III. “These publications represent the most definitive evidence to date for safety and effectiveness of IVL as adjunctive therapy in vascular intervention. In addition, specific mechanisms of benefit from IVL are clearly defined. IVL represents a quantum step forward in our ability to safely treat patients with severely calcified arteries.”
As coronary artery disease progresses, plaque in the arterial wall develops calcium deposits, which narrow the artery and restrict blood flow. When lesions are not calcified, a balloon (angioplasty) can aid in the placement of a stent. However, when the plaque hardens, the artery is more difficult to open and more aggressive approaches are needed. IVL uses sonic pressure waves, also known as shockwaves, that harmlessly pass through soft arterial tissue and preferentially disrupt calcified plaque by creating a series of micro-fractures. After the calcium has been cracked, the artery can be expanded by low pressure balloon inflation and a stent can be safely implanted to improve blood flow, with minimal trauma to normal arterial tissue. IVL received FDA approval for use in coronary arteries in February 2021 and has been cleared for the treatment of peripheral arterial disease in the United States since 2016.
