Apixaban Validation Study - Additional Study on Fresh Samples

The objective is to demonstrate the performances of STA® - Apixaban Calibrator & STA® - Apixaban Control used in combination with STA® - Liquid Anti-Xa to measure apixaban concentration in plasma. Anti-Xa results will be compared to LCMS (liquid chromatography - mass spectrometry) for validation of the assay. For this study, the anti-Xa assay will be performed on fresh samples only.

The results will be used to complete results obtained previously on frozen samples.

About this study

About 60 samples from patients on apixaban meeting inclusion/exclusion criteria will be included in this study. Two sites will be in charge of sample recruitment and anti-Xa testing. A third site will be in charge of LCMS testing.

Who can participate

Healthy volunteers accepted: No

Only the study team can determine whether someone qualifies for participation.

Inclusion criteria

  • Age ≥ 75 years,
  • Weight ≤ 60 kg,
  • Haematocrit below normal values as determined by local laboratory or < 40% for male and < 37% for female
  • Renal impairment documented (creatinine clearance ≤ 80 mL/min as per Cockcroft -Gault equation) or serum creatinine ≥ 1.5 mg/dL
  • Co-medication with aspirin or any other NSAIDs (nonsteroidal anti-inflammatory drugs)
  • Co-medication with anti-platelet agents

Exclusion criteria

  • Patients less than 18 years old
  • Patients under other anti-coagulant treatment
  • Samples that are not collected, stored, or handled in accordance with sample collection procedures defined above.

Treatment and study plan

STA-Apixaban Calibrator & Control

Device

Measurement of apixaban level will be done using anti-Xa assay (IVD).

Primary outcomes

  1. Method comparison between Anti-Xa method and LCMS to measure apixaban in plasma

    Time frame: The anti-Xa assay will be tested within 6h after sample collection and LCMS will be performed on frozen samples, at maximum 2 months after collection.

    Compare results from anti-Xa assay and LCMS to measure apixaban in plasma samples. Regression and difference charts will be used to compare the methods.
