Trial Outcomes & Findings for Clinical Performance Evaluation of Pefakit® PiCT® UC In Vitro Diagnostic Medical Device (NCT NCT02052544)

NCT ID: NCT02052544

Last Updated: 2015-05-06

Results Overview

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)

Plasma Samples From Subjects Receiving Unfractionated Heparin
n=123 Participants
A total of 123 valid patients were recruited over three clinical centers (two in Europe, one in the US). The patients were selected from subjects receiving UFH therapy and who have given written informed consent. Excluded from the study were subjects treated with any other anticoagulants other than UFH, subjects who have been undergoing fibrinolytic therapy within the previous 4 weeks, subjects known to have a congenital bleeding disorder, subjects known to show coagulation factor deficiencies and subjects known to have a coagulation inhibitor or an unexplained APTT prolongation.

PRIMARY outcome

Timeframe: within 2 - 4 days

Population: AVS (all valid subjects) population: All valid subjects with no major deviation affecting outcome.413 samples total analyzed

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)
