CLI Clinical Trials
Advancing stem cell therapy to treat critical limb ischemia
Critical limb ischemia (CLI) is the most severe form of peripheral arterial disease (PAD) caused by chronic inflammatory processes associated with atherosclerosis that result in markedly reduced blood flow to the legs, feet and hands. There are an estimated 10-12 million people with PAD in the United States and over 1 million people with CLI. To read more about critical limb ischemia, visit our critical limb ischemia information page in the Cardiovascular Disease Patients section of our website. Below is information about the status of Vericel’s CLI clinical trials.
Status: Study Ended
Study design: Phase 3, randomized, double-blind, placebo-controlled, parallel group, multicenter
Patients: Patients with CLI who have no revascularization options as confirmed by an independent, centralized Eligibility Review Committee (ERC). Patients must have tissue loss on their index leg at screening.
Purpose: To assess the efficacy and safety of ixmyelocel-T treatment compared with placebo (vehicle control) in patients with CLI. The primary objective is to assess the effect of treatment with ixmyelocel-T on amputation-free survival (AFS) at 12 months post-injection.
Locations: Approximately 80 sites in the United States

Study design: Phase 2, randomized, placebo controlled, double-blind, parallel-group, multicenter
Patients: Patients with lower extremity CLI with persistent, recurring rest pain for ~2 weeks and/or ulceration or gangrene of the foot or toe; patients were to have infrainguinal occlusive disease with no options for revascularization.
Purpose: To assess the safety and efficacy of ixmyelocel-T treatment compared with placebo (vehicle control) in patients with CLI.
Locations: Multiple sites in the United States
