Study Summary

The Perosphere Technologies' PoC Coagulometer measures clotting times of fresh whole blood samples. Clotting is initiated by glass surface activation and terminates on optical detection of fibrin assembly, the final step in the coagulation cascade. Since activation occurs at the top of the intrinsic pathway and detection occurs at the bottom of the final common pathway, the Perosphere Technologies' PoC Coagulometer has shown sensitivity to a broad range of drugs and reagents that affect blood clotting processes, including the Direct Oral Anticoagulants, DOACs (e.g. rivaroxaban, apixaban, and edoxaban), as well as the heparins (e.g. enoxaparin, a low molecular weight heparin, and unfractionated heparin). The purpose of the present study is to characterize the performance of the PoC Coagulometer measuring Clotting Time Controls, as well as fresh whole blood from both healthy volunteers and DOAC patients at three field testing sites.

Eligibility Criteria

Inclusion

Inclusion Criteria:

  • Be informed of the nature of the study and provide written informed consent before anystudy-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.
  • Healthy volunteers must: Not be on medication designed to alter the coagulation stateof a patient (including anticoagulants, anticoagulant reversal agents, plateletinhibitors, NSAIDs and thrombolytics or "clot buster" drugs), except as specified forphase 3 of testing.
  • Eligible patients on anticoagulants must: Have taken their prescribed anticoagulantregularly at least for a month prior to study participation for inclusion in phase 3of testing
  • Eligible patients on anticoagulants must: Have been on their anticoagulant therapy forat least one month.

Exclusion

Exclusion Criteria:

  • Have any of the following findings at Study Enrollment (information will be collectedvia questionnaire): Positive pregnancy test (females); Drug- or alcohol abuse; Use oftobacco or nicotine-containing products within 3 months prior to screening
  • 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 history of unexplained syncope.
  • Have a history within 6 months prior to Screening of major bleeding, trauma, surgicalprocedure of any type, or vaginal delivery.
  • Have a history within 6 months prior to Screening of peptic ulcer or gastrointestinalbleeding (including hematemesis, melena, or rectal bleeding).
  • Have received any blood product or anticoagulant within 3 months prior to Screening.
  • Have donated blood or blood products within 3 months prior to Screening.
  • Have a history of minor bleeding episodes (e.g., epistaxis, bruising or gingivalbleeding) within 1 month prior to screening, or a long-standing history of suchbleeding.
  • If female, have a history of excessive or dysfunctional uterine bleeding (unless thesubject had a subsequent hysterectomy).
  • If female, be pregnant, breastfeeding, or planning to become pregnant during thestudy. Eligible patients on anticoagulants must not:
  • 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, other than thecondition for which a DOAC was prescribed.
  • Have a history of unexplained syncope.
  • Have a history within 6 months prior to Screening of peptic ulcer or gastrointestinalbleeding (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 thesubject had a subsequent hysterectomy).
  • If female, be pregnant, breastfeeding, or planning to become pregnant during thestudy.
