Clinical Performance Evaluation of Pefakit® PiCT® UC In Vitro Diagnostic Medical Device

May 4, 2015 updated by: DSM Nutritional Products, Inc.
To demonstrate the substantial equivalence (SE) of Pefakit® PiCT® UC (test device, T) to aPTT-SP (Hemosil) (predicate device, P) in determining heparin levels in subjects undergoing heparin therapy in support of a United States Food and Drug Administration (FDA) 510(k) submission.

Detailed Description

Standard of Care Study. Objective is to monitor the patients' heparin levels under treatment with continuous unfractionated heparin infusions. Blood samples collections (4 ml) are required routinely. A proportion of this standard sample (leftover plasma) will be used for study purposes. About three samples will be analyzed which are collected within 2 - 4 days. Time points for blood sample collections will be defined by the treating physician according the local standard of care and will be associated exclusively to clinical considerations. Results of the Pefakit® PiCT® UC assay will NOT be used to take therapeutic decisions for study subjects.

Study Population

Subjects undergoing UFH anticoagulation therapy will are needed for this study. Typically, such patients are undergoing cardiovascular surgery, are being treated for thromboembolic events, or are receiving heparin intravenously for thrombosis prophylaxis due to its more advantageous pharmacokinetic profile in some situations.

Description

Inclusion Criteria:

  • Subjects receiving a continuous infusion with UFH
  • Subjects who have given written informed consent (unless written informed consent is waived by local regulations or local EC/IRB)

Exclusion Criteria:

  • Subjects treated with any other anticoagulants other than UFH
  • Subjects who have been undergoing fibrinolytic therapy within the previous 4 weeks
  • Subjects who are known to have a congenital bleeding disorder
  • Subjects known to present unexplained prolongations of clotting time
  • Subjects known to have coagulation factor deficiencies
  • Patient participating or who has participated within one month from enrolment in another investigational study

Primary Outcome Measures

Outcome Measure
Measure Description
Time Frame
Overall Sensitivity and Specificity of Pefakit and Hemosil.
Time Frame: within 2 - 4 days
Sensitivity is the proportion of positive cases identified as positive. Specificity is the proportion of negative cases identified as negative. The Sensitivity and Specificity of Pefakit and Hemosil were calculated for the overall study population and separately for each of the three medical centers. Sensitivity and Specificity of Pefakit and Hemosil were each assessed relative to the reference method (Biophen)
within 2 - 4 days
