A Dose Escalation and Safety Study of Plasmin (Human) In Acute Lower Extremity Native Artery or Bypass Graft Occlusion
Lead Sponsor:
Grifols Therapeutics LLC
Conditions:
Arterial Occlusive Diseases
Eligibility:
All Genders
18+ years
Phase:
PHASE1
Brief Summary
The purpose of this study is to evaluate the safety of increasing doses of intra-thrombus Plasmin (Human) in acute peripheral arterial occlusion (aPAO). The ability of these Plasmin doses to dissolve ...
Detailed Description
There is an unmet need for proven thrombolytic agent in acute peripheral arterial occlusion (aPAO). The current assortment of plasminogen activators are slow to dissolve clots in the leg, and may lead...
