ClinicalTrials.gov Identifier: NCT01312935
Recruitment Status :
(PolyMedix decided to stop enrollment in both clinical trials due to observations of reductions in blood pressure.)
PMX-60056 is being developed as a rapid and effective reversal agent for use in those situations where anticoagulation by heparin, or LMWH must be quickly stopped. Potential uses include reversal of anticoagulation induced to prevent clotting during surgical procedures, and rescue from cases of inadvertent or unexpected overdose.
The primary outcome measure of this study is the ability to reverse the anticoagulant effects of heparin (as measured by ACT) to the same extent as is known for protamine. intravenous infusion of PMX-60056. [ Time Frame: Immediately post completion of PCI procedure, until 2 hours after last dose. ]
