May 19, 2020 updated by: Perosphere Pharmaceuticals Inc, a wholly owned subsidiary of AMAG Pharmaceuticals, Inc.

Phase II Randomized, Sequential Group, Evaluation of Ascending Reversal Doses of PER977 Administered to Subjects With Steady State Edoxaban Dosing and Re-anticoagulation With Edoxaban Following PER977 Reversal

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.

Conditions

Conditions

The disease, disorder, syndrome, illness, or injury that is being studied. On ClinicalTrials.gov, conditions may also include other health-related issues, such as lifespan, quality of life, and health risks.

Intervention / Treatment

Intervention / Treatment

A process or action that is the focus of a clinical study. Interventions include drugs, medical devices, procedures, vaccines, and other products that are either investigational or already available. Interventions can also include noninvasive approaches, such as education or modifying diet and exercise.

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.

Other Outcome Measures

Other Outcome Measures

For clinical trials, a planned measurement described in the protocol that is used to determine the effect of an intervention/treatment on participants.
