The LIMBO trials are two prospective, multi-center, randomized pilot studies to document the effects of adventitial delivery of dexamethasone sodium phosphate injection (4 mg/mL) after balloon angioplasty or atherectomy of lesions below the knee in symptomatic patients with critical limb ischemia (CLI). Up to 120 patients (60 treatment and 60 control), including up to 20 Rutherford 6 patients (10 treatment and 10 control) in Europe (LIMBO-PTA, NCT02479555) and up to 120 patients (60 treatment and 60 control), including up to 20 Rutherford 6 patients (10 treatment and 10 control) in the United States (LIMBO-ATX, NCT02479620) will be enrolled in the trials. This study will assess the safety and effectiveness of Bullfrog Micro-Infusion Device adventitial deposition of dexamethasone in reducing inflammation and restenosis in patients with clinical evidence of chronic critical limb ischemia with an angiographically significant lesion in the infrapopliteal crural vessels.
