Pluristem Completes Interim Enrollment in Pivotal CLI Study, Targeting Potential Conditional Marketing Approval in Europe


HAIFA, Israel, April 29, 2019 (GLOBE NEWSWIRE) -- Pluristem Therapeutics Inc. (Nasdaq:PSTI) (TASE:PSTI), a leading regenerative medicine company developing novel placenta-based cell therapy products, today announced the Company has achieved a significant milestone in its ongoing development of PLX-PAD for the treatment of critical limb ischemia (CLI). The company has met its enrollment timelines relating to its Phase III pivotal study in CLI sooner than expected, and has successfully enrolled over 50% of the study’s patients, which allows for an interim analysis of efficacy after a one-year follow-up period under the European Medicine Agency’s (EMA) Adaptive Pathways pilot project, which PLX-PAD was selected for. The interim analysis, if positive, could support an application for conditional marketing approval, which could accelerate the approval and commercial availability of PLX-PAD in the Europe.

Pluristem also announced today the official initiation of its U.S. Food and Drug Administration (FDA)-approved Expanded Access Program (EAP), with several site initiations in the U.S. This program makes Pluristem’s PLX-PAD cell therapy product available to CLI patients who are unsuitable for inclusion in the Company’s ongoing multinational Phase III clinical study. The EAP will enroll up to 100 patients with Rutherford Category 5 CLI and provides Pluristem the opportunity to collect data while the global Phase III study is ongoing. Pluristem previously announced that it received approval from the FDA for cost recovery for patient treatments administered under the EAP. 

“Pluristem’s development program for its novel cell therapy, PLX-PAD, for the treatment of CLI continues to progress, and we are rapidly approaching a significant data milestone with a potential interim efficacy analysis that could expedite commercial availability in Europe,” stated Zami Aberman, Chairman and Co-Chief Executive Officer of Pluristem. “We are pleased to see positive collaboration from our clinical sites, where we beat our expected timelines for patient enrollment. We will use the remaining year to prepare the company for its potential application for conditional marketing approval in Europe under the adaptive pathway designation. We look forward to conducting this interim analysis with the goal of making this promising therapy available to patients as quickly as possible.”

“CLI is a devastating disease that can result in diminished quality of life and a high risk of amputation and death. With lack of suitable non-surgical therapeutic options for the growing population of CLI patients, new approaches such as cell therapy are warranted. In multiple completed studies to date, PLX-PAD demonstrated significant improvement in reducing the risk for amputation and death, improved tissue perfusion and reduced ischemic pain, all while demonstrating a very favorable safety profile.” Mr. Aberman concluded, “We are glad to receive the FDA’s support for our EAP and are privileged to be able to provide PLX-PAD to patients in need, with the goal to prevent amputations and save lives.”

The Phase III CLI program has been awarded a €7.6 million grant from the European Union’s Horizon 2020 program, which is its largest EU research and innovation program. The collaborative project includes leading European research institutes and clinical sites, which undertake an extensive scientific program in parallel to the trial, using in-depth immunological, endocrine, and molecular analyses to better understand the mechanism of action of PLX-PAD in CLI.

In addition to the EMA’s Adaptive Pathways program and the FDA’s EAP, PLX-PAD has been granted FDA Fast Track Designation for the treatment of CLI.

About Critical Limb Ischemia (CLI)
Critical Limb Ischemia (CLI) is the most severe form of peripheral artery disease (PAD), a chronic illness in which blood flow to the limbs is obstructed. PAD is the most prevalent cardiovascular disease in the world, affecting more than 200 million people, and one of the most common chronic diseases in the U.S., surpassing even cancer. It is estimated that 5-6 million people in U.S. and Europe suffer from CLI with an estimated cost of 25 billion $ per year in the U.S. alone. With the increasing rate of aging and diabetes, this number is projected to grow in the coming years. Today, up to 40% of CLI patients are unsuitable for revascularization and experience up to 40% amputation rate at 1 year, left with no medical solution other than amputation.
