Overview

This trial is active, not recruiting.

Condition healthy
Treatments per977, placebo
Phase phase 1/phase 2
Sponsor Perosphere, Inc.
Start date June 2014
End date December 2015
Trial size 60 participants
Trial identifier NCT02206087, PER977-01-002

Summary

Normal subjects will receive unfractionated heparin followed by a single dose of PER977 with dose escalation by cohort. Ten subjects enrolled in Cohort 4 will receive a single dose of PER977 followed by a one-week washout and then will receive unfractionated heparin followed by a single dose of PER977. The study will provide some insight into the doses that may be required to reverse anticoagulation induced by heparin. PER977 administration following heparin sodium injection will have an acceptable safety and tolerability profile with no impact on pro-coagulant biomarkers.
