BioLineRx Reports Successful Top-Line Safety and Efficacy Results for Novel Stem Cell Mobilization Treatment
- BL-8040 Phase 1 study met all safety and efficacy endpoints -
- High stem-cell yield supports novel single-day collection procedure -
Robust stem cell mobilization was evident in all treated participants, across the different doses tested, supporting a novel approach to stem cell collection. After a single administration, BL-8040 enabled collection of a yield of stem cells that exceeds the number required to support a transplant in all treated participants, following only one collection procedure. The Company intends to present the full set of study results at the
“We are very enthusiastic about the study results showing the outstanding activity of BL-8040 in promoting stem cell mobilization. The results exceeded our expectations, and validate BL-8040 as a highly differentiated stand-alone treatment for stem-cell collection. We plan to meet with the
The Phase 1 safety and efficacy study consisted of two parts. The first part was a randomized, double-blind, placebo-controlled, dose escalation study exploring the safety and tolerability of escalating repeated doses of BL-8040 in three cohorts of eight healthy volunteers. Based on data from the first part, an optimal safe and efficacious dose of BL-8040 was selected, which was used as a stand-alone therapy in a single cohort of eight healthy volunteers in the second open-label part of the study. This part of the study was designed to assess BL-8040’s stem cell mobilization capacity, as well as the yield of cells collected by apheresis. Secondary efficacy endpoints of the study included the pharmacodynamic and pharmacokinetic profile of the drug, as well as an evaluation of the viability and biological activity of cells mobilized by BL-8040 and collected by apheresis.
About Stem Cell Mobilization
High-dose chemotherapy followed by stem cell transplantation has become an established treatment modality for a variety of hematologic malignancies, including multiple myeloma, as well as various forms of lymphoma and leukemia. Modern peripheral stem-cell harvesting often replaces the use of traditional surgical bone marrow stem-cell harvesting. In the modern method, stem cells are mobilized from the bone marrow using granulocyte colony-stimulating factor (G-CSF), often with the addition of a mobilizing agent such as Plerixafor (Mozobil), harvested from the donor’s peripheral blood by apheresis, and infused to the patient after chemotherapy ablation treatment. This treatment is highly effective, the peripheral stem cells are easier to collect, and the treatment allows for a quicker recovery time and fewer complications.
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, when combined with G-CSF, 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. Pre-clinical studies show that BL-8040 inhibits the growth of various tumor types including multiple myeloma, non-Hodgkin's lymphoma, leukemia, non-small cell lung carcinoma, neuroblastoma and melanoma. BL-8040 significantly and preferentially stimulated apoptotic cell death of malignant cells (multiple myeloma, non-Hodgkin's lymphoma and leukemia). Significant synergistic and/or additive tumor cell killing activity has been observed in-vitro and in-vivo when tumor cells were treated with BL-8040 together with Rituximab, Bortezomib, Imatinib, Cytarabine and the FLT-3 inhibitor AC-220 (in
