Study of PER977 Administered to Subjects With Steady State Edoxaban Dosing and Re-anticoagulation With Edoxaban
- Conditions
- Anticoagulation Reversal
- Interventions
- Registration Number
- NCT02207257
- Lead Sponsor
- Perosphere Pharmaceuticals Inc, a wholly owned subsidiary of AMAG Pharmaceuticals, Inc.
- Brief Summary
This study will evaluate the establishment of anticoagulation ("re-anticoagulation") of subjects with edoxaban following reversal by PER977 and will identify a dose regimen of PER977 that reverses the effects of edoxaban for up to 21 hours.
- Detailed Description
This is a randomized, single-blind, sequential group, ascending PER977 reversal dose study in healthy volunteers. Subjects will be randomized in a 4:1 ratio to receive either PER977 or placebo. All subjects will receive a single dose of edoxaban 60 mg on Days 1-4. On Days 3 and 4, study drug will be administered 3 hours following edoxaban. Beginning with Cohort 2, study drug will be administered only to those subjects with a minimum increase in whole blood clotting time \>25% above baseline.
Pharmacokinetic assessment of PER977 and tis metabolite, and edoxaban and its metabolite will be performed. Pharmacodynamic assessment of WBCT and Point of Care prothrombin time will be performed. Safety will be assessed throughout the study.

- Primary Outcome Measures
Name Time Method Whole blood clotting time as a measure of edoxaban anticoagulation reversal by PER977 5 days To evaluate the safety, tolerability and effect on whole blood clotting time of escalating intravenous doses of PER977 (25, 50, 100, 300 mg, and 600 mg) administered after 60 mg edoxaban as a "rescue" medication in healthy volunteers and repeated for a second day to investigate any effects of PER977 on the re-anticoagulation with edoxaban and second reversal with PER977.
- Secondary Outcome Measures
Name Time Method Pharmacokinetic profile of edoxaban 5 days To evaluate the maximal concentration, half-life, and clearance of edoxaban and its metabolite when administered with PER977
Safety coagulation measures 5 days To evaluate changes in point of care prothrombin time, d-dimer, prothrombin factors 1 and 2, tissue factor pathway inhibitor, and possibly other biomarkers following escalating intravenous doses of PER977 administered after edoxaban in healthy volunteers
Safety and tolerability 5 days To determine if adverse events occurred in healthy volunteers who received PER977 after edoxaban
Pharmacokinetic profile of PER977 5 days To assess the maximal concentration, half-life and plasma and urinary clearance of PER977 and its metabolite following intravenous administration
