Official title
Study for Evaluation of Clinical Ranges of Whole Blood Clotting Times
Overview
Whole blood clotting time measurements are to collect the clotting time ranges for DOAC-anticoagulated patients and assess their correlation with plasma drug levels (via anti-FXa assay).
Detailed description
Primary objectives of the planned whole blood clotting time measurements are to collect the clotting time ranges for DOAC-anticoagulated patients and assess their correlation with plasma drug levels (via anti-FXa assay).
Interventions
- Diagnostic test Whole Blood Clotting Time
Comparator
Primary outcome measures
- Clotting times of whole blood samples, measured on Perosphere Technologies' PoC Coagulometer devices [Time frame: Immediate]
Secondary outcome measures (1)
- Drug concentrations in collected blood samples as measured through anti-factor Xa (anti-Xa) assay [Time frame: Immediate]
Eligibility criteria
Inclusion criteria
- In general, study participants must:
- Be informed of the nature of the study and provide written informed consent before any study-specific procedures are performed.
- Be 18- to 80-years-of-age, inclusive, at time of consent.
- Have suitable venous access for at least a single venipuncture.
- Eligible patients on anticoagulants must have taken their prescribed anticoagulant regularly at least for one month prior to study participation for inclusion
Exclusion criteria
- Eligible patients on anticoagulants must not:
- Other than the condition for which a DOAC was prescribed , have a personal or family history of clotting disorder or hematologic abnormality, such as excessive bleeding, joint hematoma, thrombovascular disease, thrombocytopenia, or any chronic condition requiring treatment with transfusions.
- Have a BMI> 40 or weight > 120kg.
- Suffer from renal or hepatic insufficiency.
- Suffer from any pathology that would contra-indicate in general DOAC medication.
- Have a history of unexplained syncope.
- Have a history within 6 months prior to Screening of peptic ulcer or gastrointestinal bleeding (including hematemesis, melena, or rectal bleeding).
- Consume more than 5 cigarettes per day.
- If female, have a history of excessive or dysfunctional uterine bleeding (unless the subject had a subsequent hysterectomy).
- If female is pregnant, breastfeeding, or planning to become pregnant during study
