JERUSALEM, Dec. 10, 2013 /PRNewswire/ -- BioLineRx (NASDAQ: BLRX; TASE: BLRX), a biopharmaceutical development company, announced today that positive preclinical results of BL-8040 (formerly known as BKT-140), for the treatment of Acute Myeloid Leukemia (AML) and other hematological indications, have been presented as a poster at the 55th Annual Meeting of the American Society of Hematology (ASH). The data show that BL-8040 is efficient in inducing the death of AML cancer cells both in vitro and in a humanized mouse model.

BL-8040 is a novel, potent and selective inhibitor of the CXCR4 chemokine receptor, which is normally activated by the chemokine ligand CXCL12. Both CXCL12 and its receptor, CXCR4, are key players in enabling AML cancer cells to hide and thrive in the bone marrow, and CXCR4 expression in AML patients is associated with poor prognosis. FLT3 mutations are detected in approximately 30% of AML cases and are associated with poor prognosis and a high incidence of relapse in AML patients. In addition, expression of the CXCR4 receptor in FLT3 mutated AML is also correlated with poor outcomes. Accordingly, it is believed that inhibition of CXCR4 may sensitize AML cells toward chemotherapy and FLT-3 targeted therapies.
The data presented in the conference show that BL-8040 directly inhibits AML cell growth and induces cell death, both in cell cultures and in mice engrafted with human AML cells. In addition, the ability of BL-8040 to induce mobilization of AML cells from the bone marrow into the blood circulation enhanced the chemotherapeutic effect of ARA-C (one of the standard-of-care chemotherapies for AML). The effects were even more robust in cells harboring the FLT3 mutation and a synergistic effect was observed when BL-8040 was combined with the FLT3 inhibitor AC220 (Quizartinib).
Dr. Kinneret Savitsky, Chief Executive Officer of BioLineRx, stated, “BL-8040, one of our key clinical-stage assets, is part of the personalized medicine revolution that aims to deliver precise, efficient therapy specifically tailored to each individual cancer patient. Indeed, the results presented in the ASH conference show that BL-8040 is highly effective in directly inducing AML cell death and in augmenting the effects of other drugs, resulting in an exceptionally high percentage of cell growth inhibition and death. These promising results further support the data we have accumulated to date, all indicating that BL-8040 has the potential to significantly improve personalized treatment for AML patients. We are looking forward to the partial results of the Phase 2 clinical trial in humans expected this month, with final results expected in the second half of 2014. Furthermore, based on the new pre-clinical data, we intend to perform a specific review of efficacy in the current Phase 2 study regarding those patients with the FLT3 mutation.”
About BL-8040
BL-8040 is a clinical-stage drug candidate for the treatment of acute myeloid leukemia, as well as other hematological indications. It is a short peptide that functions as a high-affinity antagonist for CXCR4, a chemokine receptor that is directly involved in tumor progression, angiogenesis (growth of new blood vessels in the tumor), metastasis (spread of the disease to other organs or organ parts) and cell survival. CXCR4 is over-expressed in more than 70% of human cancers and its expression often correlates with disease severity. In a Phase 1/2, open-label, dose escalation, safety and efficacy clinical trial in 18 multiple myeloma patients, BL-8040 demonstrated an excellent safety profile at all doses tested and was highly effective in the mobilization of hematopoietic stem cells and white blood cells from the bone marrow to the peripheral blood.
BL-8040 also mobilizes cancer cells from the bone marrow and may therefore sensitize these cells to chemo- and bio-based anti-cancer therapy. Importantly, BL-8040 has also demonstrated a direct anti-cancer effect by inducing apoptosis (cell death). Pre-clinical studies show that BL-8040 is efficient, both alone and in combination with the anti-cancer drug Rituximab, in reducing bone marrow metastasis of lymphoma cells and stimulating lymphoma cell death. BL-8040 was licensed by BioLineRx from Biokine Therapeutics and was previously developed under the name BKT-140.
