Clinical Trials

Date: 2014-04-10

Type of information: Initiation of the trial

phase: 1-2

Announcement: initiation of a study

Company: BioLineRx (Israel)

Product: BL-8040

Action mechanism:

peptide. BL-8040 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. BL-8040 has been shown to induce the mobilization of healthy hematopoietic stem cells from the bone marrow into the peripheral blood. BL-8040 also mobilizes cancer cells from the bone marrow and other sites and may therefore expose these cells to chemo- and bio-based anti-cancer therapy and induce 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.

Disease:

chronic myeloid leukemia

Therapeutic area: Cancer - Oncology

Country: Israel

Trial details:

The study is designed as a Phase 1/2, randomized, dose-escalation study to assess the combination of BL-8040 with standard-of-care imatinib for improving the response of CML patients in the first chronic phase of the disease who have achieved a less than optimal response with Imatinib alone. Primary endpoints of the study are the safety and tolerability of BL-8040 in combination with Imatinib, and the secondary endpoints include assessing the efficacy of the combination therapy in achieving improved cytogenetic and molecular response in CML patients. The study will be performed at the Sheba Medical Center, and will include up to 40 patients.

Latest news:

* On April 10, 2014, BioLineRx, a clinical-stage biopharmaceutical company dedicated to identifying, in-licensing and developing promising therapeutic candidates, has announced  that Prof. Arnon Nagler, Director of the Hematology Division and Bone Marrow Transplantation Center at Sheba Medical Center, Israel, has received final regulatory approval to evaluate BioLineRx’s BL-8040 as a treatment for chronic myeloid leukemia (CML) in a Phase 1/2 clinical study. BioLineRx is currently developing BL-8040 in a Phase 2 study for treating acute myeloid leukemia (AML), and in a Phase 1 study for stem cell mobilization, as a pre-treatment for stem cell transplantation. The Company has received orphan drug designation for both these indications.

* On February 12, 2014, BioLineRx, a clinical-stage biopharmaceutical company, has announced positive pre-clinical results for BL-8040 in a third indication - as a treatment for chronic myeloid leukemia (CML). Results of the study were recently published in Molecular Cancer Therapeutics (Combination of Imatinib with CXCR4 antagonist BKT140 overcomes the protective effect of stroma and targets CML in vitro and in vivo.

The study, led by Prof. Arnon Nagler, Director of the Hematology Division and Bone Marrow Transplantation Center at Sheba Medical Center, Israel, assessed the effect of BL-8040 alone, and in combination with imatinib, on the proliferation of human CML cells in culture and on human CML tumors that were engrafted in mice. Results of the study show that the BL-8040 treatment directly inhibited cancer cell growth and induced apoptotic cell death of CML cells in vitro. Furthermore, BL-8040 had a synergistic effect with imatinib, enabling use of imatinib at low doses. In mice engrafted with CML tumors, the combination of BL-8040 with low-dose imatinib markedly inhibited tumor growth, achieving a 95% suppression. The novel drug reversed the protective effect of the bone marrow stroma on CML cells, effectively promoting their apoptosis.

BL-8040 is currently undergoing a Phase 2 trial for acute myeloid leukemia and is expected to enter a Phase 1 trial for stem cell mobilization in the second quarter of this year, with top-line results for both of these studies expected in the fourth quarter of 2014.
