Devilish cunning is now employed to find new ways to interrupt the clotting cascade in such a way as to prevent unwanted thrombosis without increasing the risk of bleeding. A new target is factor XI, and you will be interested to learn that factor XI levels can be lowered with FXI-ASO (ISIS 416858), a 2\u2032-O-(2-methoxyethyl) (2\u2032-O-MOE) second generation antisense oligonucleotide that specifically reduces human factor XI messenger RNA expression in the liver. Well, Isis Pharmaceuticals would like you to be interested anyway, and have persuaded the <em>NEJM<\/em> to accept what <a href=\"http:\/\/www.nejm.org\/doi\/full\/10.1056\/NEJMoa1405760\">appears to be a phase 2 open label trial of the drug<\/a> in 300 patients about to undergo unilateral knee replacement, with enoxaparin as the comparator. Their drug had an equal protective effect with less bleeding. But when you are thinking of giving a preventive treatment to millions of healthy people, you need quite a lot more evidence than this.<\/p>\n<p><strong><em>Lancet<\/em> 13 December 2014 Vol 384<\/strong><\/p>\n<p><strong>Ultrathin Strut Biodegradable Polymer Sirolimus-Eluting Stent vs. Durable Polymer Everolimus-Eluting Stent for Percutaneous Coronary Revascularization (pg. 2111):<\/strong> Does the world need new stents?
