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.

哈里·马格纳尼(Harry Magnani)通过ResearchGate发布(第八条链接):
"没有理由不撤稿。我很惊讶,在如今所有试验都应完成注册的时代,竟然还能为美国食品药品监督管理局(FDA)选择性公布试验结果!药企的行为属于欺诈且不道德,甚至应该被列入FDA的黑名单,因为他们隐瞒关键信息危及了患者生命。
我曾在欧加农制药公司(Organon BV)负责多款抗血栓药物(Orgaran和 Arixtra)的临床开发,我可以坦诚地说,所有与疗效和安全性相关的数据,包括特殊人群如肾功能不全患者的用药影响,都已完成研究并在给药建议中进行了合理阐释。此外,由于该药物的临床适应症主要见于老年患者(无论男女),我们在临床开发阶段特意纳入了尽可能多的老年受试者。
但我也曾因为拒绝撤回对Arixtra的评价而遭到赛诺菲(Sanofi)的不满:在主要深静脉血栓形成(DVT)预防试验完成后,我认为该药物可能引发血小板减少症,进而可能导致肝素诱导的血小板减少症(HIT)——尽管该情况发生率极低(不足1%),但最终我的观点得到了证实。药企应当谨记,药物研发的首要目的是服务患者,盈利应位居其次。
请注意:我退休后曾为阿斯彭制药(Aspen Pharmacare)提供独立咨询服务,我并非、也从未是该公司的雇员。"

["你本可以拥有一款更安全的药物",《英国医学杂志(BMJ)》调查编辑德博拉·科恩博士说道,她上月发表了两篇批评泰毕全(Pradaxa)记录的文章。通过密切监测患者的药物血药浓度,"与控制良好的华法林相比,你可以将严重出血风险降低30%至40%",她补充道。]

**备注:**
我同意德博拉·科恩的观点。补充两点:
1. 大部分测量了出血临床结局的I期临床试验仍未发表。
2. 这些试验的部分数据并未在勃林格殷格翰的官方网页公开。此外,多数报告仅为摘要,未提供达比加群各期(I至III期)临床试验的详细信息。上述问题已在本数据集的推特消息中讨论并附相关内容。
