Ra Medical Systems Announces Substantial Completion of Audit Committee Investigation

CARLSBAD, Calif. (October 31, 2019)– Ra Medical Systems, Inc. (NYSE: RMED), a medical device company focusing on commercializing excimer laser systems to treat vascular and dermatological diseases, today announced that the Audit Committee of the Board of Directors (the “Audit Committee”) has substantially completed its internal investigation, which was originally announced in August. The Audit Committee, assisted by independent legal counsel, Morrison & Foerster LLP, conducted a thorough investigation of allegations raised by an employee, as well as additional matters discovered during the course of the investigation.

The Audit Committee’s primary investigative findings are: (i) the DABRA catheter frequently failed to calibrate and occasionally overheated, posing a risk of injury to physicians and patients; (ii) the Company’s explanations regarding the Company’s fourth quarter 2018 and first quarter 2019 sales created a risk of confusion because they did not explicitly reference inconsistent DABRA catheter performance and catheter failures; (iii) the Company failed to timely make at least two Medical Device Reports, or MDRs, to the FDA; (iv) the Company, out of a concern for the DABRA catheters’ performance, engaged in systematic efforts to replace product held by customers, which constituted product recalls, but were not documented as such, (v) the Company lacks documentation of sufficient detail and specificity to support certain payments to physicians, ostensibly for training and consulting services, and as to three physicians did not accurately reflect the purpose and nature of approximately $300,000 of payments, which could be perceived as an improper attempt to obtain business or to gain special advantage, (vi) while the indication for use in the 510(k) clearance the Company obtained for the DABRA system is not for atherectomy, the Company’s salespeople were instructed to characterize DABRA as performing atherectomy and to encourage doctors to seek reimbursement using atherectomy codes, (vii) Company determinations to direct potentially valuable benefits and opportunities to doctors were informed in part by sales prospects, and (viii) the Company received complaints regarding regulatory or compliance concerns that, because they implicated executive officers, should have been brought to the attention of the Board or the Audit Committee, but were not.

The Audit Committee, in reviewing the allegations, identified certain behavior inconsistent with the Company’s Code of Ethics and Conduct and related policies involving certain current and former executive officers and employees of the Company. With respect to current Company executives and employees, the Audit Committee referred these matters to the Board or the Company for appropriate action and discipline.

The Audit Committee made a number of recommendations which the Board of Directors has adopted, including: separation of certain employees, implementing additional and enhanced policies and training, strengthening the Company’s quality regulatory systems, and adopting certain enhanced controls related to the matters investigated.

In addition, the Company has continued to take steps in an effort to improve the performance and reliability of the Company’s DABRA laser system, including hiring a VP, Quality, Regulatory and Clinical, conducting extensive internal and external audits of its quality systems, clinical trial data and manufacturing process, as well as initiating the previously announced voluntary recall of DABRA catheters.

Based on the results of the investigation, the Company is in the process of evaluating the impact of the results of the investigation on its previously issued or announced financial statements, and its internal controls over financial reporting and compliance procedures.

As previously disclosed, due to the Audit Committee investigation the Company has not filed its Quarterly Report on Form10-Q for the quarter ended June 30, 2019 (the “Form10- Q”) with the SEC. The Company is working diligently to evaluate the Audit Committee investigation findings, including the assessment of the impact on the Company’s financial statements, if any, and its internal controls over financial reporting. After the conclusion of the Audit Committee investigation and the Company’s evaluation, the Company will file its Form10-Q as soon as practicable thereafter.

The Company notes that its physician customers continue to use the DABRA laser system with success, and the Company believes that the previously announced change in shelf life will significantly reduce the number of catheters that fail to calibrate and thereby improve customer satisfaction with the product. The Company is focusing its efforts on improving the manufacturing process, with the goals of improving product consistency and extending the shelf life.

In addition, in order to more effectively market DABRA, the Company currently is pursuing expanded indications for use of DABRA to include an atherectomy indication for use, which the FDA currently defines to include a prespecified improvement in luminal patency, or a prespecified increase in the openness of the artery at apre-defined time point. To satisfy the FDA’s data requirements to support an atherectomy indication, the Company submitted an investigational device exemption, or IDE, designed to gather the clinical data necessary to determine substantial equivalence in support of the atherectomy indication. This IDE was approved in July 2019. However, as a result of the DABRA catheter recall to change the shelf life, the Company plans to submit updates to the IDE and enroll the first patient in the first quarter of 2020.

As also previously announced, the Company voluntarily contacted the SEC regarding the Audit Committee’s investigation. In October 2019, the Department of Justice provided the Company with a Civil Investigative Demand seeking information with respect to a False Claims Act investigation concerning whether the Company fraudulently obtained 510(k) marketing clearance for its ablation devices marketed under the trade name DABRA (which is not an item that has been investigated by the Audit Committee), whether the Company marketed and promoted DABRA devices for unapproved uses that were not covered by federal healthcare programs, and whether the Company paid improper remuneration to physicians and other healthcare providers in violation of the Anti-Kickback Statute, 42 U.S.C.§1320a-7b. The Company intends to cooperate with the SEC and the Department of Justice’s inquiries or investigations.
