Cardiovascular Systems, Inc. Announces Commercial Launch in Japan

ST. PAUL, Minn.

Cardiovascular Systems, Inc. (CSI) (NASDAQ: CSII), a medical device company developing and commercializing innovative interventional treatment systems for patients with peripheral and coronary artery disease, announced today that it has commercially treated the first patient in Japan with its Diamondback 360® Coronary OAS Micro Crown (Micro Crown).

Following CSI’s COAST trial, the device was approved by Japan’s Pharmaceuticals and Medical Devices Agency (PMDA) as a frontline treatment for de novo severely calcified lesions and to facilitate access to the arteries for percutaneous coronary interventions (PCI) post procedure.

COAST was a Harmonization-By-Doing clinical study for the Micro Crown conducted in both the United States and Japan under the regulations of both governments. In Japan, COAST was led by the National Principal Investigator, Dr. Shigeru Saito, of Shonan Kamakura General Hospital, Kamakura City, Japan.

Dr. Saito, who treated the first patient, said, “Patients with severely calcified coronary lesions are some of the most difficult to treat, leading to unfavorable clinical and economic outcomes. The commercialization of the Micro Crown in Japan provides physicians with a new technology to treat this unmet medical need.”

Orbital atherectomy has demonstrated clinical advantages compared to historical rotational atherectomy data, including lower rates of target lesion revascularization (TLR) and persistent slow flow/no reflow. CSI’s Micro Crown is the only atherectomy system designed to both pilot tight, calcific coronary lesions and treat larger vessels up to 4mm with a single device. The company’s ORBIT II and COAST clinical studies demonstrated that OAS is safe and effective in treating patients with de novo severely calcified coronary lesions.

Dr. Jan B. Pietzsch, President and CEO of health economics consultancy Wing Tech Inc. and Director, Health Economics and Value, Stanford Byers Center for Biodesign, who studied the Clinical and Economic Challenges of Calcified Lesion Treatment, said, “In a post hoc economic subanalysis, orbital atherectomy was associated with a reduction in one-year reintervention costs when compared to historical rotational atherectomy data. This is due to the reduced need for repeat revascularization, lower cardiac mortality and fewer devices used per procedure.”

CSI received PMDA approval for the Micro Crown in March 2017 and reimbursement approval effective February 2018. Medikit Co., Ltd. is CSI’s exclusive distribution partner in Japan. With a controlled launch now underway, CSI expects to complete an initial Micro Crown stocking order during its third fiscal quarter and open approximately 15 accounts by the end of the fiscal year.

Scott Ward, Chairman, President and Chief Executive Officer of CSI, concluded, “We are excited to bring orbital atherectomy technology to Japan. Ten to twenty percent of the 280,000 Japanese patients who undergo percutaneous coronary procedures each year have severely calcified coronary lesions. The introduction of Micro Crown gives physicians in Japan a cost-effective treatment option for this difficult-to-treat patient population.”

U.S. Diamondback 360® Coronary Orbital Atherectomy Systems

Indications: The Diamondback 360 Coronary Orbital Atherectomy Systems (OAS) are percutaneous orbital atherectomy systems indicated to facilitate stent delivery in patients with coronary artery disease (CAD) who are acceptable candidates for PTCA or stenting due to de novo, severely calcified coronary artery lesions.

Contraindications: The OAS are contraindicated when the ViperWire guide wire cannot pass across the coronary lesion or the target lesion is within a bypass graft or stent. The OAS are contraindicated when the patient is not an appropriate candidate for bypass surgery, angioplasty, or atherectomy therapy, or has angiographic evidence of thrombus, or has only one open vessel, or has angiographic evidence of significant dissection at the treatment site and for women who are pregnant or children.

Warnings/Precautions: Performing treatment in excessively tortuous vessels or bifurcations may result in vessel damage; The OAS was only evaluated in severely calcified lesions; A temporary pacing lead may be necessary when treating lesions in the right coronary and circumflex arteries; On-site surgical back-up should be included as a clinical consideration; Use in patients with an ejection fraction (EF) of less than 25% has not been evaluated. See the instructions for use before performing Diamondback 360® Coronary OAS procedures for detailed information regarding the procedure, indications, contraindications, warnings, precautions, and potential adverse events. For further information call CSI at 1-877-274-0901 and/or consult CSI’s website at www.csi360.com.

Caution: Federal law (USA) restricts this device to sale by or on the order of a physician.
