Both Intramuscular and Intravenous Administrations Show Statistically Significant ImprovementClinical Path Being Investigated With Leading Medical Institutions
HAIFA, Israel I October 1, 2013 I Pluristem Therapeutics Inc. (PSTI) (TASE:PLTR), a leading developer of placenta-based cell therapies, announced today that the company’s PLacental eXpanded (PLX) cells demonstrated efficacy in a preliminary animal experiment for the treatment of Graft versus Host Disease (GvHD) following bone marrow transplantation (BMT). The results showed that PLX cells, regardless of their administration route, intravenous (IV) or intramuscular (IM), demonstrated a statistically significant improvement (p
GvHD may occur after BMT when patients receive bone marrow tissue or cells from a donor and these newly transplanted cells regard the recipient’s body as foreign, attacking the recipient’s body. The global incidence of acute GvHD ranges from 26% to 34% in recipients of fully matched sibling donor grafts, to 42% to 52% in recipients of matched unrelated donor grafts.
The animal study was conducted in the laboratories of the Department of Bone Marrow Transplantation, Hadassah Medical Center, the Hebrew University, Jerusalem.
In the study, mice underwent total body irradiation and after twenty-four hours received a semi-allogeneic BMT. PLX cells, or the same volumes of the control vehicle, were then injected IV or IM into the mice concurrently with the BMT (day 0, ~20h after irradiation) and 5 days post-irradiation. PLX markedly reduced the GvHD score, comprised of weight loss, diarrhea, skin and fur integrity and survival. This significant (p
“Based on the results of this pre clinical study suggesting our PLX cells may be effective in GvHD, we are pleased with the interest of leading medical institutions to use our PLX cells and will consider a cooperation to advance into a clinical program for this indication,” said Zami Aberman, Chairman and CEO of Pluristem. “This indication would be complementary to the other indications we plan to pursue in the hematology field. Additionally, this study also gives Pluristem another data point demonstrating PLX cells do not have to be given intravenously to obtain a systemic effect.”
IM Administration with Systemic Effect
This preclinical study marks the second time that the IM administration of PLX cells has demonstrated a systemic effect with efficacy in a hematological disease and the fourth time when preclinical animal models for other indications are included. Pluristem previously reported that the IM injection of PLX cells demonstrated a systemic effect in preclinical studies of Peripheral Artery Disease (PAD), Preeclampsia and Acute Radiation Sickness (ARS). Additionally, systemic, beneficial effects were also noted in three patients given PLX cells IM compassionately for Bone Marrow Failure.
About Pluristem Therapeutics
Pluristem Therapeutics Inc. is a leading developer of placenta-based cell therapies. The Company’s patented PLX (PLacental eXpanded) cells are a drug delivery platform that releases a cocktail of therapeutic proteins in response to a host of local and systemic inflammatory and ischemic diseases. PLX cells are grown using the company’s proprietary 3D micro-environmental technology and are an “off-the-shelf” product that requires no tissue matching prior to administration.
Pluristem has a strong intellectual property position, company-owned GMP certified manufacturing and research facilities, strategic relationships with major research institutions and a seasoned management team.
