• Pluristem enters into agreement with WideTrial Inc. to conduct the program
  • WideTrial will purchase PLX-PAD cell products from Pluristem
  • Program makes investigational treatment available to CLI patients who are unsuitable for inclusion in the Company’s ongoing multinational Phase 3 clinical study
  • Allows for collection of real-world data concurrent with the Phase 3 study

HAIFA, Israel and SAN FRANCISCO, Oct. 16, 2018 (GLOBE NEWSWIRE) -- Pluristem Therapeutics Inc. (Nasdaq:PSTI) (TASE:PSTI), a leading regenerative medicine company developing novel placenta-based cell therapy products, and WideTrial Inc., a privately-held third-party sponsor of authorized Expanded Access Programs (EAPs), today announced that the parties have entered into agreement to initiate an FDA-cleared EAP for Pluristem’s cell therapy product, PLX-PAD, for the treatment of critical limb ischemia (CLI). The parties further announced that the FDA has authorized WideTrial to charge payment for the PLX-PAD EAP treatment. Under the terms of the EAP, an initial 100 Rutherford-5 CLI patients who are ineligible for inclusion under Pluristem’s ongoing Phase 3 study protocol, and whose condition is life-threatening, will be enrolled.

“Patients suffering from critical limb ischemia are often unsuitable for revascularization and therefore experience poor clinical outcomes, including amputation. The condition can be fatal if left untreated,” said Yaky Yanay, Co-CEO and President of Pluristem. “We believe the FDA’s decision to approve this Expanded Access Program with cost-recovery for this novel and potentially life-saving cell therapy reflects the Agency’s comfort with the safety profile of PLX-PAD, and recognition of its potential use in treating CLI patients who have few remaining treatment options. As we progress through the EAP, we look forward to generating valuable real world data concurrent with our ongoing 246-patient Phase 3 study that we are currently enrolling in U.S., Europe and Israel. Together, these clinical initiatives are expected to yield a significant body of evidence that we believe will support the safety and efficacy of PLX-PAD and may represent a significant advancement in the treatment of CLI.”    

“We are pleased to make PLX-PAD more widely available to CLI patients in need while allowing Pluristem’s management to stay focused on its ongoing Phase 3 clinical study,” said Jess Rabourn, Chief Executive Officer of WideTrial. “Expanded Access Programs allow pre-market treatment use of new medicines by patients who suffer from severe conditions and who cannot enroll in regular clinical studies. These programs can also generate real world data from a wider range of patients in the target population, insights from which could help inform further development of this particular study drug.”

Pluristem’s PLX-PAD program has been selected for accelerated approval pathways in both the U.S. and Europe, including the FDA’s Fast Track Designation and the European Medicines Agency’s (EMA) Adaptive Pathways program.

CLI is an advanced stage of peripheral artery disease where fatty deposits block arteries in the legs, leading to pain, non-healing ulcers, and gangrene. Patients with CLI, particularly later stages of the disease (Rutherford Categories 5 and 6) have a high risk of amputation and death, and those unsuitable for revascularization are left with no adequate treatment options. Pluristem’s PLX-PAD cell therapy utilizes placental cells to secrete a range of therapeutic proteins that trigger the body’s own repair mechanisms, allowing it to grow blood vessels, bring oxygenated blood to damaged tissue, and heal itself faster.
