Stem cell mobilizer: Burixafor


Burixafor is a potent and selective CXCR4 chemokine receptor antagonist discovered and developed by TaiGen. Burixafor rapidly mobilizes stem cells and progenitor cells from the bone marrow into peripheral circulation. Potential indications include:

Stem cell transplantation – increasing the yield of stem cells harvested for transplantation and reducing side effects

Hematological cancer chemosensitization – for mobilizing malignant cells hidden in the bone marrow and render them to killing by chemotherapeutic agents

Treatment in myocardial infarction – for mobilizing endothelial progenitor cells to restore heart function and reducing necrotic heart muscle tissue

A Phase I trial in healthy volunteers and a Phase II POC trial in autologous hematopoietic stem cell transplantation were completed under IND with the US FDA. Responses from the multiple myeloma patients indicate that burixafor alone is sufficient to mobilize sufficient stem cells for transplantation without the need to use granulocyte-colony stimulating factor (G-CSF), the current standard-of-care. Mobilization with G-CSF is a lengthy and costly procedure and may cause significant side-effects such as bone pain. These encouraging results were presented at the 2013 American Society of Hematology Annual Meeting in New Orleans, USA.

Burixafor also mobilizes hematological cancer cells residing in the bone marrow that are inaccessible to chemotherapeutic agents, which is a major cause for disease recurrence. Treatment with Burixafor prior to chemotherapy could mobilize these malignant cells in the bone marrow and render them to killing by chemotherapeutic agents eliminating residual diseases and extending survival time. TaiGen have initiated chemosensitization studies in AML (acute myeloidc leukemia) patients in China.

In addition to oncology indications, TaiGen and its collaborator have shown Burixafor’s utility in ischemic diseases in pre-clinical studies. In a mouse ischemic limb model, TaiGen have demonstrated that Burixafor’s could effectively enhance blood flow, increase blood vessel formation and improve limb functions. Furthermore, in two different animal models of myocardial infarction, Burixafor greatly reduced the infarct size, and also increased the ventricular ejection volume. Based on these results, burixafor could offer a novel and effective treatment for ischemic diseases.
