Brief Summary:
This study will assess the safety and efficacy of intramuscular injection of AMG0001 (hepatocyte growth factor [HGF] plasmid) to improve ulcer healing and perfusion in patients with peripheral artery disease.
| Condition or disease | Intervention/treatment | Phase |
|---|---|---|
| Peripheral Artery Disease Ischaemic Ulcer of Lower Leg Due to Atherosclerotic Disease Chronic Limb Threatening Ischemia Ischemic Ulcer of Foot | Biological: AMG0001 Biological: Placebo | Phase 2 |
This is a Phase 2, double-blind, randomized, placebo-controlled, parallel group study. Approximately 60 male or female subjects aged 18 years or older with one shallow foot ulcer and mild/moderate ischemia due to peripheral artery disease (PAD) will be randomized in a 1:1:1 ratio to one of 3 treatment groups:
- 4.0 mg AMG0001 intramuscular (IM) (n = 20)
- 8.0 mg AMG0001 IM (n = 20)
- Placebo IM (n = 20)
| Study Type : | Interventional (Clinical Trial) |
| Estimated Enrollment : | 60 participants |
| Allocation: | Randomized |
| Intervention Model: | Parallel Assignment |
| Masking: | Quadruple (Participant, Care Provider, Investigator, Outcomes Assessor) |
| Primary Purpose: | Treatment |
| Official Title: | A Phase II Double-Blind, Randomized, Placebo-Controlled Study to Assess the Efficacy and Safety of AMG0001 to Improve Ulcer Healing and Perfusion in Subjects Who Have Peripheral Ischemic Ulcers of the Lower Extremity |

Primary Outcome Measures :
- Complete ulcer healing at 6 months [ Time Frame: Month 6 ]Complete ulcer healing defined as skin re-epithelialization without drainage or dressing requirements confirmed at 2 consecutive study visits 2 weeks apart.
- Time to complete ulcer healing [ Time Frame: Month 12 ]Complete ulcer healing defined as skin re-epithelialization without drainage or dressing requirements confirmed at 2 consecutive study visits 2 weeks apart.
Secondary Outcome Measures :
- The percentage reduction of ulcer size from baseline [ Time Frame: Months 4, 6, 8, 10, 12 ]
- Hemodynamic measurements of toe pressure (TP) [ Time Frame: Months 4, 6, 8, 10, 12 ]Measure of baseline and change from baseline for hemodynamic parameters
- Hemodynamic measurements of ankle systolic pressure (ASP) [ Time Frame: Months 4, 6, 8, 10, 12 ]Measure of baseline and change from baseline for hemodynamic parameters
- Hemodynamic measurements of ankle brachial index (ABI) [ Time Frame: Months 4, 6, 8, 10, 12 ]Measure of baseline and change from baseline for hemodynamic parameters
- Hemodynamic measurements of toe brachial index (TBI) [ Time Frame: Months 4, 6, 8, 10, 12 ]Measure of baseline and change from baseline for hemodynamic parameters
- Hemodynamic measurements of TcPO2 [ Time Frame: Months 4, 6, 8, 10, 12 ]Measure of baseline and change from baseline for hemodynamic parameters
- Visual Analogue Scale (VAS) [ Time Frame: Months 4, 6, 8, 10, 12 ]Measure of baseline and change from baseline for VAS. VAS is a 10-cm line (with score ranges 0 to 10), oriented horizontally; the left end of the line (0 mark) indicates "no pain"; the right end indicates "pain as bad as it can be."
- Occurrence of New Ulcer of the Index leg [ Time Frame: Months 4, 6, 8, 10, 12 ]Number of subjects and proportions with new ulcer
- Major / Minor Amputations (digit, forefoot) / Revascularization of the Index Leg [ Time Frame: Months 4, 6, 8, 10, 12 ]Number of subjects and proportions with major/minor amputation or revascularization

Criteria
Inclusion Criteria:
- 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
Exclusion Criteria:
- 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
