Safety/Feasibility Study of HBOC-201 in Amputation at/Below Knee From Critical Lower Limb Ischemia
Phase II, Multi-Center,Single-Blind,Placebo-Controlled Study,Evaluating Safety & Feasibility of HBOC-201 (Wound Healing Patients With Peripheral Vascular Disease & Undergoing Lower Limb Amputation Due to Critical Lower Limb Ischemia
The purpose of this study is to assess the safety and feasibility of HBOC-201 in increasing adequate wound healing in patients with severe peripheral vascular disease who are undergoing lower limb amputation.
The hypothesis is that HBOC-201 will pass through the partially occluded lesions in the peripheral arteries in the lower extremity and promote the wound healing process by delivering oxygen to the oxygen deprived tissues. This will reduce the incidence of lower limb wound complications at 60 days post-surgery and may reduce the incidence of a second amputation.
