Pluristem’s Phase III Study of PLX-PAD Cells for the Treatment of Critical Limb Ischemia Cleared by U.S. FDA

HAIFA, Israel, Jan. 10, 2017 (GLOBE NEWSWIRE) -- Pluristem Therapeutics Inc. (PSTI) (PSTI), a leading developer of placenta-based cell therapy products, today announced that the Company’s Phase III study of its PLX-PAD cells in the treatment of critical limb ischemia (CLI) was cleared by the U.S. Food and Drug Administration (FDA). Pluristem’s strategy is to use this single multinational Phase III study to support the submission of a biologics license application (BLA) to the FDA for marketing approval. Pluristem expects to begin enrolling patients in its Phase III study in both the U.S. and Europe during the first half of 2017.

“We are excited to have received FDA clearance to initiate our Phase III study for this very important indication. Our PLX-PAD product candidate provides hope for a new, effective treatment and a better quality of life for millions of CLI patients. Pluristem is committed to advancing its peripheral artery disease programs in CLI and intermittent claudication (IC) worldwide,” stated Pluristem Chairman and CEO Zami Aberman.

“The use of a time-to-event endpoint in our CLI trial, as is employed in many advanced clinical trials, will allow us to gather more data during the trial thereby significantly reducing the number of patients needed. Data from previous clinical studies have shown that, by increasing tissue perfusion, PLX-PAD may improve the healing of wounds in CLI patients, and could allow for significant delays in events of amputation or death in the treated group,” Mr. Aberman concluded.

In CLI, fatty deposits block arteries in the leg, leading to greatly reduced blood flow, pain at rest, non-healing ulcers, and gangrene. Patients with CLI are at an immediate risk for limb amputation and death. With poor treatment options, CLI patients who cannot undergo revascularization procedures have a severe unmet medical need.

Pluristem’s Phase III CLI study will be a double blind, randomized, placebo controlled trial of about 250 patients with CLI Rutherford Category 5 who are unsuitable for revascularization. At an estimated 40 clinical sites in the U.S. and Europe, patients will be treated with 300 million PLX-PAD cells or placebo, injected twice intramuscularly (IM), with the second injection administered two months after the first. The primary endpoint is time to amputation or death. The European Medicines Agency (EMA) previously selected the PLX-PAD program in CLI for its Adaptive Pathways pilot project, which may allow for conditional marketing approval after a single pivotal study.
