Pharmacokinetics and Point of Care Testing of Direct Oral Anticoagulants Subjects

Registration Number
NCT05491460
Lead Sponsor
Doasense GmbH
Brief Summary

DOACs are increasingly used since 8 years. Standard coagulation tests (Prothrombin time \[PT\] and activated partial thromboplastin time \[aPTT\]) from plasma samples show a high variation. Special coagulation tests like hemoclot for dabigatran and chromogenic substrate assays for Rivaroxaban, Apixaban, and Edoxaban are time-consuming and can be performed only in specialized laboratories. In specific medical situations like in patients such as emergency procedures, stroke (before starting thrombolytic therapy), trauma, general surgery or other invasive procedures, it may be necessary for medical decision making to know the presence or absence of a DOAC in patient's body fluid. Until now there is no rapid, specific and sensitive coagulation test available in the market.

Detailed Description

This prospective, open-label, controlled, not randomized trial in healthy volunteers to investigate comparatively the pharmacokinetics of the direct oral anticoagulants in plasma and in urine with LC-MS/MS and in urine by DOAC Dipstick.

ApixabanApixaban 5 MG TabVolunteers receive one oral dose of 5mg Apxiaban followed by sequential blood and urine sampling over 72 hours During the study liquid-chromatography mass-spectrometry analysis is performed in plasma and urine and DOAC Dipstick in urine. Biological and clinical safety parameters are measured.
DabigatranDabigatran 150 MG TabVolunteers receive one oral dose of 150mg Dabigatran followed by sequential blood and urine sampling over 72 hours During the study liquid-chromatography mass-spectrometry analysis is performed in plasma and urine and DOAC Dipstick in urine. Biological and clinical safety parameters are measured.
RivaroxabanRivaroxaban 20 MG TabVolunteers receive one oral dose of 20mg Rivaroxaban followed by sequential blood and urine sampling over 72 hours During the study liquid-chromatography mass-spectrometry analysis is performed in plasma and urine and DOAC Dipstick in urine. Biological and clinical safety parameters are measured.
EdoxabanEdoxaban 60Mg TabVolunteers receive one oral dose of 60mg Edoxaban followed by sequential blood and urine sampling over 72 hours During the study liquid-chromatography mass-spectrometry analysis is performed in plasma and urine and DOAC Dipstick in urine. Biological and clinical safety parameters are measured.
