• Tel Aviv Sourasky Medical Center will act as the sponsor of the study
  • PLX-PAD cells have demonstrated efficacy in preclinical models of GvHD             

HAIFA, Israel, Nov. 06, 2017 (GLOBE NEWSWIRE) -- Pluristem Therapeutics Inc. (NASDAQ:PSTI) (TASE:PSTI), a leading developer of placenta-based cell therapy products, today announced that it has signed an agreement with Tel Aviv Sourasky Medical Center (Ichilov Hospital) to conduct a Phase I/II trial in PLX-PAD cell therapy for the treatment of Steroid-Refractory Chronic Graft-versus-Host-Disease (GvHD).  

The trial will be an investigator initiated study.  As such, Tel Aviv Sourasky Medical Center will support the study and will be responsible for its design and implementation. Dr. Ron Ram, Director of the Hematology Blood and Marrow Stem Cell Transplantation Unit for the Tel Aviv Sourasky Medical Center will act as principal investigator.

GvHD is a potentially lethal complication of hematopoietic cell transplantation (HCT) from a donor. When a patient receives a donor’s stem cells, the transplanted cells identify the patient’s body as foreign and attack it. The chronic form of GvHD occurs at least 100 days following the transplantation. The GvHD market is predicted to exceed $500 million by 2023.

Preclinical studies showed that Pluristem’s PLX-PAD cell product potentially mitigates symptoms of GvHD, and in addition the secretion profile and mechanism of action properties suggest that it may be a novel and effective treatment for the condition. Pluristem hopes to address this severe unmet medical need and help patients lead full lives after undergoing a transplant.

“We’re excited to work with Pluristem towards developing an effective treatment for chronic GvHD,” noted Dr. Ron Ram at the Tel Aviv Sourasky Center. “Our Clinical Research Center is a hub for groundbreaking treatments and is the perfect testing ground for Pluristem’s cell therapy.”

“Studies have shown that our PLX cells have beneficial effects in a number of hematologic indications. We are very pleased to enter into this collaboration with Tel Aviv Sourasky Medical Center while continuing to focus on advancing our lead indications into pivotal and Phase III studies,” said Zami Aberman, Chairman and Co-CEO of Pluristem. “Our unique, proprietary technology platform and the versatility of our cells allow us to develop our cell products to treat a number of conditions with inadequate treatment options. We look forward to offering new hope to patients worldwide.”

About Chronic GvHD

Chronic GvHD occurs in approximately 40% of patients who have received a transplant of hematopoietic stem cells sourced from the bone marrow or peripheral blood of a donor. These hematopoietic stem cell transplants are used to treat some blood or bone marrow cancers as well as other hematologic conditions, such as aplastic anemia, which are not related to cancer. The donated cells identify the recipient’s body as foreign and attack it as a result. While acute GvHD usually appears in the first 100 days after a transplant, and in specific body systems, chronic GvHD can occur at any time (even several years) after a transplant, and may manifest in many parts of the body such as: skin, mouth, eyes, liver, intestines, lungs and joints. Long term immunosuppression is given to try to prevent or treat chronic GvHD. Since this treatment suppresses the immune system for a very long time, patients are at high risk of infections, and are prescribed multiple medications to try to address this major risk.
