HSCs are cells found in the bone marrow, peripheral blood, or umbilical cord blood, that are responsible for generation and replenishment of all blood cell progenitors and eventually mature cells. HSC engraftment is therefore beneficial for a variety of therapeutic purposes, such as transplantation for people with blood or bone marrow cancer, or for the therapy of blood or immune system disorders. The success of long-term HSC engraftment depends largely on the amount and quality of a specific type of HSC (CD34+CD38−CD45RA−CD90+ CD49f+), but these specific cells are rare, making it difficult to collect large numbers of these HSCs.
"HSCs are important for the treatment of various blood cancers, as well as blood and bone marrow pathologies. In addition, the specific subpopulation of HSCs investigated in this study may improve the longevity of stem-cell engraftment. Unfortunately, stem-cell harvesting with current standard of care (G-CSF) generally contains low numbers of these rare cells," said
The talk at ASH entitled "The CXCR4 antagonist BL-8040 Induces a Robust Mobilization of CD34+CD38−CD45RA−CD90+ CD49f+ HSCs with Long-Term and Secondary Myeloid and Lymphoid Repopulating Activity" will be delivered by Professor Amnon Peled from the Hadassah Medical Center and Biokine Therapeutics.
BL-8040 is a short peptide for the treatment of acute myeloid leukemia, solid tumors, and stem cell mobilization. It functions as a high-affinity antagonist for CXCR4, a chemokine receptor that is directly involved in tumor progression, angiogenesis, metastasis and cell survival. CXCR4 is over-expressed in more than 70% of human cancers and its expression often correlates with disease severity. In a number of clinical and pre-clinical studies, BL-8040 has shown robust mobilization of cancer cells from the bone marrow, thereby sensitizing these cells to chemo- and bio-based anti-cancer therapy, as well as a direct anti-cancer effect by inducing cell death (apoptosis). In addition, BL-8040 has also demonstrated robust stem-cell mobilization, including the mobilization of colony-forming cells, T, B and NK cells. BL-8040 was licensed by BioLineRx from Biokine Therapeutics and was previously developed under the name BKT-140.
BioLineRx is a clinical-stage biopharmaceutical company focused on oncology and immunology. The Company in-licenses novel compounds, develops them through pre-clinical and/or clinical stages, and then partners with pharmaceutical companies for advanced clinical development and/or commercialization.
BioLineRx's leading therapeutic candidates are: BL-8040, a cancer therapy platform, which has successfully completed a Phase 2a study for relapsed/refractory AML, is in the midst of a Phase 2b study as an AML consolidation treatment and is expected to initiate a Phase 3 study in stem cell mobilization for autologous transplantation; and AGI-134, an immunotherapy treatment in development for multiple solid tumors, which is expected to initiate a first-in-man study in the first half of 2018. In addition, BioLineRx has a strategic collaboration with
