CryoLife Receives Conditional IDE Approval to Begin Clinical Trials for PerClot® in the U.S.
ATLANTA, June 19, 2013 /PRNewswire/ -- CryoLife, Inc. (NYSE: CRY), a leading tissue processing and medical device Company focused on cardiac and vascular surgery, announced today that it has received conditional approval of its Investigational Device Exemption (IDE) for PerClot from the United States Food and Drug Administration (FDA).
PerClot is a unique hemostat composed of absorbable polysaccharide granules and is intended for use in surgical procedures as an adjunctive hemostatic device when control of capillary, venular, and arteriolar bleeding by pressure, ligature, and other conventional means is ineffective or impractical. PerClot has CE Mark designation and CryoLife began distributing PerClot in several international markets in the fourth quarter of 2010. PerClot international sales were up 34 percent in the first quarter of 2013 compared to the first quarter of 2012.
"We're pleased to reach this initial milestone toward the commercialization of PerClot in the U.S.," stated Steven G. Anderson, CryoLife president and chief executive officer. "Subject to satisfaction of the FDA's conditions, we plan to begin enrollment in the pivotal trial in the third quarter of 2013, and hope to have pre-market approval in 2015."
The U.S. hemostatic market is estimated to be $889 million in 2012 growing to approximately $1.1 billion in 2014, while the European market is estimated to be $361 million in 2012 growing to approximately $430 million in 2014.
The PerClot IDE is a prospective, multicenter, multidisciplinary, controlled clinical investigation. The primary objective of this investigation will be to collect clinical data concerning the safety and efficacy of PerClot versus a similar marketed hemostatic device in multiple surgical disciplines when used as an adjunct to conventional means of achieving hemostasis such as pressure or ligature. The primary efficacy endpoint of this investigation will be achievement of hemostasis at the site of application at 5 minutes following application of the prescribed hemostatic agent. The secondary efficacy endpoint for this investigation will be hemostasis at the site of application evaluated at 2 minutes. Safety endpoints will include, but are not limited to, the incidence of reoperation due to bleeding, total hospitalization and procedure time, and the incidence of procedure complications and/or adverse events through final patient follow-up.
As part of the conditional approval for the PerClot IDE, CryoLife must make certain revisions to the investigational study protocol, clinical product labeling and Patient Informed Consent forms. The Company anticipates refiling the IDE submission in July. The Company expects to begin enrollment in the general and urological surgical cohorts during the third quarter. The Company will have further discussions with the FDA to clarify the requirements prior to enrollment in the cardiac and orthopedic indications.
PerClot is a medical device composed of absorbable polysaccharide granules and delivery applicators. The granules are biocompatible, non-pyrogenic, and derived from purified plant starch. The granules do not contain any human or animal components. PerClot granules have a molecular structure that rapidly absorbs water, forming a gelled adhesive matrix that provides a mechanical barrier to further bleeding and results in the accumulation of platelets, red blood cells, and coagulation proteins (thrombin, fibrinogen, etc.) at the site of application. One gram of PerClot absorbs at least 19 mL of water. The gelled adhesive matrix thus promotes the normal physiological clotting cascade. PerClot granulaes are enzymatically degraded by alpha-amylase and glucoamylase and by macrophages. Based on preclinical studies, absorption normally requires several days and is dependent on the amount of material applied on the wound and the site of use.
PerClot is intended for use in surgical procedures as an adjunctive hemostatic device when control of capillary, venular, and arteriolar bleeding by pressure, ligature, and other conventional procedures is ineffective or impractical.
PerClot is ready to use, requiring no mixing and/or other components and does not need special handling or storage conditions. Preclinical evaluations, clinical studies and surgical use have shown the efficacy of PerClot to be comparable to the current popular choice of surgical hemostatic materials while its unique formulation allows for superior rapid absorption.

Statements made in this press release that look forward in time or that express management's beliefs, expectations or hopes are forward-looking statements within the meaning of the Private Securities Litigation Reform Act of 1995. Such forward-looking statements reflect the views of management at the time such statements are made and are subject to a number of risks, uncertainties, estimates, and assumptions that may cause actual results to differ materially from current expectations. These statements include those regarding the timing, plans and expectations related to the clinical testing of PerClot, pre-market approval, the re-filing of the IDE submission, the completion of revisions to the investigational study protocol, clinical product labeling and Patient Informed Consent forms, and the estimated growth of the U.S. and European hemostatic markets by 2014. Risks potentially impacting these statements include the following: We may be unable, in the FDA's judgment, to satisfy the conditions imposed by the FDA as part of the conditional approval for the PerClot IDE, and the FDA may impose additional conditions that could negatively impact the timing and final FDA approval of the clinical trials. There is no guarantee that the FDA will approve PerClot for distribution in the U.S. in accordance with our expected timeframe, if at all. Clinical trials are subject to a number of risks, including unanticipated reactions or results, and we may ultimately be unsuccessful in our clinical trials and/or may be unable to obtain FDA approval to market PerClot in the U.S. Our approval efforts, including clinical testing and regulatory submissions, for PerClot in the U.S. are subject to delays and cost overages, and management plans with respect to clinical testing, regulatory submissions and regulatory approvals are subject to change at any time based on the overall needs of the Company. Even if we receive approval, we may be unsuccessful in our attempts to sell PerClot in the U.S. as other competing products may have penetrated the market by that time. In addition, if we are ultimately able to obtain approval from the FDA to sell PerClot, we will likely end up in a patent infringement lawsuit with Medafor, Inc., which will be expensive. If we lose, we may be prohibited from selling PerClot or may have to pay substantial royalties or damages when we sell PerClot in the U.S. Our ability to fully realize our investment in Starch Medical, Inc. is dependent on our ability to sell PerClot in the U.S. Growth of U.S. and European hemostatic markets is subject to a number of factors, including economic conditions, government regulations, patient and physician acceptance, technology advances and competition from other products. Our estimates regarding the growth of the hemostatic markets may be incorrect and the markets may shrink, or fail to grow as expected, due to factors beyond our control, including general economic conditions. To the degree that our estimates regarding the growth of the hemostatic markets are correct, there is no guarantee that we will successfully grow sales within these markets. CryoLife's business is also subject to a number of risks and uncertainties, including the risk factors detailed in our Securities and Exchange Commission filings, including our Form 10-K filing for the year ended December 31, 2012, our Form 10-Q for the quarter ended March 31, 2013, and the Company's other SEC filings. The Company does not undertake to update its forward-looking statements.
