About this study

Official title: 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.

Read the 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.

On Day 3 and 4, they will receive a single dose of 60 mg edoxaban, followed 3 hours later by a single dose of 600 mg PER977 or placebo (n=10). A protocol amendment expanded the cohort to include an additional 2 placebo and up to an additional 4 active subject.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Whole blood clotting time as a measure of edoxaban anticoagulation reversal by PER977

    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.

    Measured: 5 days

Secondary outcomes (4)
  1. Pharmacokinetic profile of PER977

    To assess the maximal concentration, half-life and plasma and urinary clearance of PER977 and its metabolite following intravenous administration

    Measured: 5 days

  2. Pharmacokinetic profile of edoxaban

    To evaluate the maximal concentration, half-life, and clearance of edoxaban and its metabolite when administered with PER977

    Measured: 5 days

  3. Safety coagulation measures

    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

    Measured: 5 days

  4. Safety and tolerability

    To determine if adverse events occurred in healthy volunteers who received PER977 after edoxaban

    Measured: 5 days

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing PER977 and Edoxaban in people with Anticoagulation Reversal, run by Perosphere Pharmaceuticals Inc, a wholly owned subsidiary of AMAG Pharmaceuticals, Inc. at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 7 inclusion and 17 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: finished, as of the sponsor's last update on 21 May 2020. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

What does this phase mean?

Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.

Not every study follows the same path, and some studies (observational studies, device studies) have no phase.

Are results available for this study?

The study is completed, but results are not available in the source record. That does not mean the treatment did or did not work.

How can a doctor refer a patient or contact the research team?

The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Whole blood clotting time as a measure of edoxaban anticoagulation reversal by PER977 (time frame: 5 days). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT02207257, which also lists 1 linked publication.

Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 21 May 2020.
