Study of AMG0001 to Improve Ulcer Healing and Perfusion in Subjects With Peripheral Ischemic Ulcers

Open to people ages 18 years and up

• Documented diagnosis of PAD and mild/moderate foot ischemia (WIFI ischemia grades 1, 2)
• A single measurable ulcer of ≥ 1 cm2 and ≤ 10 cm2 on a lower extremity without evidence of infection or gangrene and no evidence of bone and/or tendon involvement at randomization
• Subjects will undergo protocol-defined standardized wound care during the screening period and through 12 months from the first dose of investigational product
• Subjects who have a diagnosis of diabetes must be considered stable with no changes in diabetic medication regimen anticipated during the study period. Subjects who have a diagnosis of diabetes must have a HbA1c of ≤12% at Screening

• Subjects who have excessive tissue necrosis that is unlikely to benefit from medication, or those subjects who, in the opinion of the Investigator, are felt likely to require revascularization within 1 month of screening
• Subjects with severe limb ischemia
• Subjects who are considered likely to require a major amputation (at or above the ankle) within 3 months of screening
• Subjects with deep ulcerations with bone or tendon exposure, or uncontrolled infection, or with the largest ulcer that is >10 cm2 in area
• Subjects with hemodynamically significant aorto-iliac occlusive disease
• Subjects who have had a technically successful revascularization by surgery or angioplasty within 2 months. If subjects are more than two months from revascularization and still meet the inclusion criteria, they may be considered for enrollment. Subjects who have had a technically unsuccessful attempt at revascularization may be enrolled at least one week from the procedure
• Subjects currently receiving immunosuppressive medication, systematically administered steroid therapy, chemotherapy or radiation therapy. Inhaled and topical steroid therapies are allowed
