Pluristem reports positive topline Phase I results in innovative hematology program, which is first to study PLX-R18 in humans
HAIFA, Israel, April 29, 2021 (GLOBE NEWSWIRE) -- Pluristem Therapeutics Inc. (Nasdaq:PSTI) (TASE: PSTI), a leading regenerative medicine company, today reported positive topline results in its first study to evaluate the safety and exploratory efficacy of PLX-R18 in humans. The company’s Phase I, open-label, dose-escalation study is evaluating the safety and exploratory efficacy of intramuscular injections of PLX-R18 in subjects with incomplete hematopoietic recovery following Hematopoietic Cell Transplantation (HCT).
Pluristem CEO and President, Yaky Yanay, said, "The promising topline results demonstrate insight into how PLX cells may provide a more effective therapeutic benefit than current technologies. We believe that PLX-R18 affects the regeneration activity of the hematopoietic cells. By supporting blood cell lineage’s recovery, this approach could be used to address a variety of hematological deficiencies. We intend to push forward the clinical development of PLX-R18 with the goal of establishing it as the new standard of care in the field."
Poor graft function is a life-threatening complication for patients undergoing HCT. Current standard-of-care treatments do not develop satisfactory blood counts in some or all blood cell lineages. Consequently, patients are vulnerable to bleeding and recurrent infections, and require repeated costly transfusions of blood products, which only provide a short-term effect. Pluristem's PLX-R18 aims to improve the standard of care by stimulating the regenerative potential of the bone marrow. This potentially enhances the production of all three blood cell lineages, differentiating it from other products which target only one of the three blood cell lineages.
The study enrolled 21 patients in the U.S. and Israel, who were at least three months after the HCT procedure (median: 236 days), and had low blood counts in at least one blood cell lineage. They were assigned to one of three treatment arms: 1 million cells/kg, 2 million cells/kg or 4 million cells/kg. Each patient received two treatments of the assigned dose.
The results demonstrate that PLX-R18 has the potential to stimulate the implanted hematopoietic cells to realize their therapeutic potential and generate improved blood counts over the long term in all three blood cell lineages at once – a meaningful advantage over other existing and proposed treatments.
Available data1 at six-month follow-up demonstrates:
PLX-R18 is the first product candidate manufactured using Pluristem’s proprietary serum-free media on its 3D bioreactor system.

For example, Pluristem is using forward-looking statements when it discusses that PLX cells may provide a more effective therapeutic benefit than current technologies, that PLX-R18 may potentially enhance the production of three blood cell lineages, the belief that PLX-R18 affects the regeneration activity of the hematopoietic cells and its intention to push forward with the clinical development of PLX-R18 with the goal of establishing it as the new standard of care in the field. These forward-looking statements and their implications are based on the current expectations of the management of Pluristem only, and are subject to a number of factors and uncertainties that could cause actual results to differ materially from those described in the forward-looking statements. The following factors, among others, could cause actual results to differ materially from those described in the forward-looking statements: changes in technology and market requirements; Pluristem may encounter delays or obstacles in launching and/or successfully completing its clinical trials; Pluristem’s products may not be approved by regulatory agencies, Pluristem’s technology may not be validated as it progresses further and its methods may not be accepted by the scientific community; Pluristem may be unable to retain or attract key employees whose knowledge is essential to the development of its products; unforeseen scientific difficulties may develop with Pluristem’s process; Pluristem’s products may wind up being more expensive than it anticipates; results in the laboratory may not translate to equally good results in real clinical settings; results of preclinical studies may not correlate with the results of human clinical trials; Pluristem’s patents may not be sufficient; Pluristem’s products may harm recipients; changes in legislation may adversely impact Pluristem; inability to timely develop and introduce new technologies, products and applications; loss of market share and pressure on pricing resulting from competition, which could cause the actual results or performance of Pluristem to differ materially from those contemplated in such forward-looking statements.
