NCT00420667
Because the impairment of platelet function may cause excess peri-operative bleeding, pre-operative aspirin discontinuation and heparin bridging are common at cardiac surgery. We aimed to evaluate the impact of a low-molecular-weight-heparin (LMWH), enoxaparin, and unfractionated heparin (UFH) on coagulation parameters and peri-operative bleeding in patients undergoing elective coronary artery bypass grafting (CABG) surgery after aspirin discontinuation. The specific hypothesis of this study was that a 12 h interval is sufficient not to cause excess peri-operative bleeding, and is therefore an optimal compromise between antithrombotic efficacy and haemorrhagic safety.
NCT00508820
This protocol will provide open label romiplostim to adult thrombocytopenic subjects. Romiplostim will be administered by subcutaneous injection once per week. Dose adjustment will be based on platelet counts, and will be allowed throughout the duration of the study. Rescue therapies are allowed at any time during the study. Reductions in concurrent ITP therapies may occur at any time when platelet counts are \> 50,000.
NCT04491552
This is a prospective, multi-center, observational study. Subjects will have OmniGraf™ (TruGraf® and TRAC™) testing at study enrollment and thereafter every 3 months. In addition subjects will have OmniGraf™ (TruGraf® and TRAC™) testing at any time there is a clinical suspicion of acute rejection. Data collection for the primary objective extends over a 2-year period.
