STENTYS (FR0010949404 – STNT), a medical technology company commercializing the world's first and only self-apposing stent to treat Acute Myocardial Infarction (AMI), today reports its half-year results for the six months to 30 June 2012, approved at the Board of Directors meeting on 30 August 2012.

As previously announced, STENTYS recorded revenues of €1,149.6 thousand during the first half of 2012. This 91.9% increase compared to the first half of 2011 reflects the growing routine use of STENTYS stents in hospitals in the 8 European countries where premarketing activities are taking place.

This lower increase in operating expenses relative to the increase in revenues is the result of ongoing strict spending controls whilst investments in strategic activities continue (US regulatory activities, new products, presence at medical conferences).

Research & Development costs increased 33.6% over the period, totaling €1,614 thousand, corresponding to the development of new products and to the preparation of the FDA file. Sales & Marketing costs increased by 43.5% to €3,058 thousand. These costs reflect a strengthening of the Company’s sales activity, including an expansion of the sales team and a major presence at cardiology conferences such as EuroPCR in Paris. General & Administrative costs remained stable at €977 thousand, compared to €979 thousand a year earlier. STENTYS currently has a headcount of 31 staff.

At 30 June 2012, STENTYS had a cash position of €16.7 million.

In the first half of 2012, some major strategic milestones were reached. In particular, the Company announced excellent 30-day results for the APPOSITION III clinical trial on 1,000 heart attack patients, in which the rate of Major Adverse Cardiac Events (MACE) and death for the STENTYS Self-Apposing® stent was substantially lower than pooled results from recent trials with conventional stents in this patient population. The APPOSITION IV clinical trial, which will compare the new STENTYS Self-Apposing® Sirolimus-eluting stent to Medtronic’s drug-eluting stent, began at the end of June. Moreover, the Company expanded its commercial product offering with the launch of a thrombectomy device.

Additional announcements are expected during the second half of the fiscal year, including the planned presentation of 12-month interim results for the APPOSITION III clinical trial at the annual TCT congress in the United States (US) in October. Furthermore, the Company anticipates obtaining Food and Drug Administration (FDA) clearance to carry out the APPOSITION V clinical trial in the US.

Gonzague Issenmann, Chief Executive Officer and co-founder of STENTYS, concludes: “.”

Revenues for the 3 quarter of 2012 will be published on 6 November 2012.

Based in Princeton, N.J., and Paris, Stentys has developed a new generation of stents to treat acute myocardial infarction (AMI). Founded by Jacques Séguin, M.D., Ph.D., and Gonzague Issenmann, STENTYS has begun the marketing of its flagship products in a number of European countries. Its self-apposing stents adapt to the anatomic changes of the arteries in the post-infarction phase and thus prevent the malapposition problems associated with conventional stents. STENTYS stents have shown a very low one-month mortality rate amongst 1,000 high-risk AMI patients in the APPOSITION III clinical trial.
