Brief summary
PER977 administration following a single dose of enoxaparin
Detailed description
Single escalating doses of PER977 from 100 to 300 mg, of 25 mg PER977 x 4 doses will be administered following administration of enoxaparin. Serial pharmacokinetic and pharmacodynamic assessments ( whole blood clotting time) will be performed. Adverse events will be monitored.
