I am surprised that in this day and age when all trials should be registered that results could be cherry-picked for the FDA! What the manufacturer did was fraudulent and unethical and it actually deserves being put on the FDA's black-list because lives were put at risk by concealing vital information.</em> <em>I was responsible within Organon BV for the clinical development of several antithrombotic drugs (Orgaran and Arixtra) and I can honestly state that all data pertinent to both efficacy and safety, including the effect of special situations e.g. renal dysfunction, were investigated and rationalised in the dosing recommendations. Furthermore, because the clinical indications for the drug occur mainly in elderly patients (both male and female) special care was taken to include as many of these as possible in the clinical development of the drug.</em> <em>However I have also been on the receiving end of a company's displeasure (Sanofi) when I refused to retract my opinion on Arixtra after the main DVT prophylaxis trials were completed: that it could cause thrombocytopenia and therefore potentially could cause HIT - which has been vindicated albeit in a very, very small percentage of cases (less than 1%). Companies should be reminded that drugs are developed first and foremost for patients and profit should be a secondary aim.</em> <em>Please note that I perform independent consultacy work for Aspen Pharmacare in my retirement, I am not and never have been an employee of that company."</em> ----<strong>Harry Magnani</strong> ____________________________________________ <strong>August 20, 2014. 4:20AM (Bogotá time zone)</strong> <strong><em><br></em></strong><em>[“You could have had a much safer drug,” said Dr. Deborah Cohen, the investigations editor at The BMJ, who wrote two articles last month critical of Pradaxa’s record. By carefully monitoring drug levels in patients, “you could reduce major bleeds by 30 to 40 percent, compared to well-controlled warfarin,” she said.]</em> <strong>Weighing Pradaxa’s Risks<br></strong><strong>By RONI CARYN RABIN<br></strong><strong>---- 9th URL ----<br></strong><br><em><strong>Note: </strong><br></em><br>I agree with D. Cohen. Two more points:<br><br>1) The majority of phase 1 trials in which bleeding clinical outcomes were measured remain unpublished.<br><br>2) Not all data from these trials is available in the web page Boehringer. Furthermore, most reports are summaries: no detailed information about dabigatran clinical trials (phase 1 to 3). These aspects have been already discussed & attached in the Twitter messages of this fileset. ____________________________________________ <strong>August 20, 2014. 4:35AM (Bogotá time zone)</strong> Last question for Boehringer attached as a ResearchGate screencapture in this Fileset <strong>Twitter message:</strong> @deb_cohen @ChristosArgyrop @stephensenn @DavidJuurlink @Boehringer Thank you @pash22 for sharing this document.
