Novel Polymer-Free Drug-Coated Stent Demonstrates Comparable Safety and Efficacy to Conventional Drug-Eluting Stent with Durable Polymer at 12 Months

Washington DC, USA, 25 September 2010 –

BioFreedom represents the latest development in Biosensors stent technology, featuring a micro-structured abluminal surface which permits the controlled release of Biolimus A9™ without the use of a polymer. Two versions of the stent were studied in this trial – one with a drug dosage of 15.6 μg/ per mm of stent length (standard dose) and the other with a drug dosage of 7.8 μg/ per mm of stent length (low dose).

In this second cohort of the FIM trial, 107 patients were equally randomized to each of three treatment groups: BioFreedom standard dose (SD); BioFreedom low dose (LD); or Taxus Liberté. Median in-stent late lumen loss in patients receiving BioFreedom SD was 0.17 mm and in those receiving BioFreedom LD 0.22 mm, compared with a median in-stent late lumen loss of 0.35 mm in the Taxus Liberté group. BioFreedom SD demonstrated equivalent efficacy, measured by late lumen loss, compared with Taxus Liberté (P = 0.001), with a trend towards superiority (P = 0.11).

Both BioFreedom SD and BioFreedom LD demonstrated sustained safety up to 12 months, including absence of stent thrombosis.

"The results from this study are very significant as they demonstrate for the first time that a polymer free drug-coated stent is as safe and effective as a conventional drug-eluting stent with a durable polymer coating over a twelve-month period", commented Professor Grube. "I am excited about the concept of a polymer-free stent, as the rapid drug clearance and absence of a polymer drug carrier could promote more rapid vessel healing and ultimately reduce the need for longer term dual anti-platelet therapy. However, additional clinical data is required to confirm these initial encouraging results."

"These latest results confirm that we continue to lead the industry in stent innovation, first in terms of biodegradable polymer technology and now polymer-free technology", added Jeffrey B. Jump, President & CEO of Biosensors. "We are now in the process of planning larger studies with longer-term follow-up to further investigate this exciting development".

BioFreedom FIM is a prospective, multi-centre study involving 182 patients with symptomatic ischemic heart disease. It consists of a first cohort of 75 patients, with a secondary endpoint of in-stent late lumen loss at 4 months, and a second cohort of 107 patients, with a primary endpoint of in-stent late lumen loss at 12 months. In each cohort patients were randomized into three groups: those treated with BioFreedom SD; those treated with BioFreedom LD; and those treated with Taxus Liberté. Results from the first cohort, showing equivalence between BioFreedom and Taxus Liberté, were presented at TCT in 2009. The clinical status of the patients in the trial is being reported annually for five years from the date of stent implant.Biosensors International Group, Ltd ("Biosensors", "Company", BIG:SP) today announced 12-month results from the First-In-Man ("FIM") trial of BioFreedom™, a novel polymer-free drug-coated stent ("DCS") which showed a similar reduction in in-stent late lumen loss to Boston Scientific’s Taxus® Liberté® drug-eluting stent (DES), with no evidence of stent thrombosis. These results were presented by the Principal Investigator, Professor Eberhard Grube, International Heart Center Essen, Germany, as part of the First Report Investigations III session at the 22nd annual Transcatheter Cardiovascular Therapeutics ("TCT") scientific symposium, sponsored by the Cardiovascular Research Foundation.

• Avoiding long-term late adverse effects that might be attributable to the polymer;
• Improved surface integrity since there is no polymer to be sheared or peeled away from the stent struts; and
• Possible shorter need of dual-antiplatelet therapy.

ShiFu...whahha...finally u appear in this ...
so did u load any of this share..?

Need ur wise words....ohmmmmm.....
...

Thanks bro limkt009,

If BIG good,I good lah!!!

CHEERS.

DJ MARKET TALK:Biosensors +1.0% On MicroPort Debut,Stent Findings (2010/09/24 10:19AM)‏

0219 GMT [Dow Jones] Biosensors (B20.SG) +1.0% at S$1.03, extending 6.3% rise since start of this week, supported by HK listing of MicroPort Scientific (0853.HK), maker of equipment used in keyhole surgery, which started trading today. Recent interest also underpinned by several positive announcements by Biosensors since last week, including findings affirming efficiency of its stent systems. "While the positive data is not a surprise to us given that two-year data has already proven its safety and efficacy, we believe it is re-affirmative and should drive incremental market share gains," says Nomura, which has Buy call with S$1.20 target. Tips stent-maker''s upcoming BioFreedom stent as next catalyst for shares; "a potentially positive data set (on BioFreedom) will underpin Biosensors'' long-term competitiveness and may open doors to the U.S. drug-eluting stent market." Orderbook quotes tip minimal upside beyond new 52-week high of S$1.05 set in early trade. (frankie.ho@dowjones.com)
