New Data at TCT From the DISRUPT CAD Clinical Program Demonstrate Consistency of Shockwave IVL Outcomes Over Time, Across Calcium Morphologies and Between Genders<\/b><\/p>\n

SANTA CLARA, Calif., Nov. 05, 2021 (GLOBE NEWSWIRE) \u2014 Shockwave Medical, Inc. (NASDAQ: SWAV), a pioneer in the development of Intravascular Lithotripsy (IVL) to treat severely calcified cardiovascular disease, today unveiled new data confirming the safety and effectiveness of coronary IVL out to one year, a new gender analysis that found similar outcomes between men and women, and an OCT analysis that found consistent acute performance in eccentric, concentric and nodular calcified lesions. The data from the DISRUPT CAD clinical program were presented in several sessions at the 32nd<\/sup>\u00a0Transcatheter Cardiovascular Therapeutics\u00a0(TCT) annual scientific symposium of the Cardiovascular Research Foundation, in Orlando, Fla.<\/p>\n

First One-Year Outcomes Find Durability of Excellent Procedural Results<\/strong>
\nThe first one-year outcomes from the prospective, multicenter, single-arm, global investigational device exemption (IDE) DISRUPT CAD III study demonstrated low rates of major adverse cardiovascular events (MACE, 13.8 percent) and target lesion failure (11.9 percent). The MACE results were primarily driven by the rate of non-Q wave myocardial infarction (9.2 percent), demonstrating durable safety and effectiveness following lesion preparation with IVL prior to stent deployment. The MACE rate included low rates of cardiac death (1.1 percent), myocardial infarction (10.5 percent), and target vessel revascularization (6.0 percent) one year after the index procedure. In addition, target lesion revascularization (TLR), occurred in only 4.3 percent of patients and definite or probable stent thrombosis occurred in 1.1 percent of patients at one year, with only one patient having a definite or probable stent thrombosis beyond 30 days, resulting a late stent thrombosis rate of at 0.3 percent.<\/p>\n

\u201cIt is very significant that these data show sustained and persistent relative benefit of IVL for lesion preparation prior to coronary stenting, particularly since this is the first robust one-year report that has been presented on the technology,\u201d said Dean Kereiakes, M.D., FACC, FSCAI, Medical Director of The Christ Hospital Heart and Vascular Center and the Christ Hospital Research Institute; Professor of Clinical Medicine, The Ohio State University; Co-Principal Investigator of DISRUPT CAD III. \u201cThe achievement of an average stent expansion of 102 percent and a minimum stent area (MSA) of 6.5 mm2<\/sup>\u00a0at the index procedure with IVL should have predicted excellent long-term results. We were optimistic that there should be a low rate of late target lesion revascularization and stent thrombosis to one year, and that is exactly what we found following IVL.\u201d<\/p>\n

OCT<\/strong>\u00a0Analysis Finds\u00a0<\/strong>Similar MSA and Stent expansion Across Calcium Morphologies<\/strong>
\nA pooled analysis of 262 patients enrolled in OCT sub-studies from DISRUPT CAD I, II, III and IV, the largest intravascular imaging analysis of any calcium modification tool to date, confirmed that coronary IVL achieved excellent MSA and stent expansion (SE) consistently in lesions with both eccentric and concentric calcium. MSA and SE at the maximum site of calcification were similar across the four calcium arc quartiles analyzed: \u2264180\u00b0 (6.1 mm2<\/sup> & 104%), 181-270\u00b0 (6.0 mm2<\/sup> & 101%), 271-359\u00b0 (6.1 mm2<\/sup> & 98%) and 360\u00b0 (6.2 mm2<\/sup>\u00a0& 105%), respectively.<\/p>\n

In a separate analysis of calcific nodules, coronary IVL was found to have a notable acute effect on calcific nodules, which were identified in 22 percent of cases, either by flattening or fracturing the nodule, resulting in consistent MSA (6.3 mm2<\/sup> vs 6.0 mm2<\/sup>) and SE (101% vs 103%) in lesions with calcified nodules (n=54) or those without (n=194), respectively. The analysis also found that calcific nodules, defined as an accumulation of nodular calcification, or small calcium deposits, with disruption of fibrous cap on the calcified plate, were more commonly associated with concentric calcium and greater overall calcium burden.<\/p>\n

\u201cThe ability to modify calcium regardless of its morphology, whether eccentric, concentric or nodular, and have MSA and stent expansion still remain consistent shows the versatility of IVL to make a meaningful impact on clinical practice,\u201d said Ziad Ali, M.D., DPhil, Director of the DeMatteis Cardiovascular Institute and Investigational Interventional Cardiology at St Francis Hospital & Heart Center, and presenter of the data at TCT. \u201cTo date all OCT analyses of IVL reveal that the greater the calcium burden, the greater the number of fractures. These data now show that evidence of visible fracture by OCT is not necessary to achieve large MSA or adequate stent expansion, particularly in these unique, but clinically relevant sub-groups of calcification. The take home message is that IVL liberates vascular compliance in all sub-groups including eccentric lesions and calcified nodules.\u201d<\/p>\n

Coronary IVL Found Equally Safe and Effective in Men and Women<\/strong>
\nA pooled analysis of the DISRUPT CAD I, II, III and IV studies showed IVL was equally safe and effective in men and women, unlike previous findings with atherectomy.i<\/sup>\u00a0The analysis of 628 patients stratified outcomes by sex. Women in the analysis, who accounted for 23 percent of total patients, were older and more likely to have hyperlipidemia, renal insufficiency and prior myocardial infarction. Despite more frequent comorbidities and smaller vessel size in women, the primary safety endpoint of 30-day MACE for women and men was similar (8.3 percent vs 7.1 percent,\u00a0p<\/em>=0.61). The primary effectiveness endpoint of procedural success for women and men was also similar (91.7 percent vs 92.6 percent,\u00a0p<\/em>=0.72). Notably, there were also consistent post-IVL serious angiographic complications between women and men (1.6 percent vs 2.3 percent,\u00a0p<\/em>=0.75), which differs from previous atherectomy gender analyses.<\/p>\n

\u201cGiven the strong safety profile of IVL and the known higher risks of women undergoing PCI, coronary IVL is an attractive option for optimizing outcomes in female patients,\u201d said Alexandra Lansky, MD, FACC, FAHA, FSCAI, FESC, Professor of Medicine (Cardiology); Director of Yale Cardiovascular Clinical Research Program Yale University School of Medicine, New Haven, CT. \u201cWhile this is the first analysis of its kind for coronary IVL, it is highly suggestive that the technology could potentially serve as first-line therapy for women with calcified lesions, particularly if these findings can be confirmed in a larger patient cohort.\u201d<\/p>\n

Summarizing the totality of the data presented at TCT, Dr. Kereiakes commented, \u201cLooking at these data holistically, it doesn\u2019t matter whether you\u2019re in Europe, Japan or the U.S. It doesn\u2019t matter if you\u2019re in a big center, or little center. It doesn\u2019t matter which type of calcium or which type of patients you\u2019re treating. The beauty of these data are the consistency of safety and effectiveness. We found no differences with IVL. For these reasons I call IVL the great equalizer.\u201d<\/p>\n
