Balixafortide（Cat No.:I003930）is an investigational peptide antagonist that targets the chemokine receptor CXCR4, which plays a key role in immune cell migration and tumor progression. By inhibiting CXCR4, Balixafortide is believed to disrupt the tumor microenvironment, potentially enhancing the effectiveness of anti-cancer therapies. It has shown promise in clinical trials, particularly in combination with other anti-cancer agents, for treating various cancers, including breast cancer and hematologic malignancies. Balixafortide is being explored for its ability to reduce metastasis and improve therapeutic responses in cancer treatment. It is still undergoing evaluation in clinical research.

Mobilization of hematopoietic stem cells with the novel CXCR4 antagonist POL6326 (balixafortide) in healthy volunteers-results of a dose escalation trial.Karpova D,Bräuninger S,Wiercinska E,Krämer A,Stock B,Graff J,Martin H,Wach A,Escot C,Douglas G,Romagnoli B,Chevalier E,Dembowski K,Hooftman L,Bonig H, PMID: 28049490 PMCID: PMC5209880 DOI: 10.1186/s12967-016-1107-2 </br><span>Abstract:</span> BACKGROUND: Certain disadvantages of the standard hematopoietic stem and progenitor cell (HSPC) mobilizing agent G-CSF fuel the quest for alternatives. We herein report results of a Phase I dose escalation trial comparing mobilization with a peptidic CXCR4 antagonist POL6326 (balixafortide) vs. G-CSF.METHODS: Healthy male volunteer donors with a documented average mobilization response to G-CSF received, following ≥6 weeks wash-out, a 1-2 h infusion of 500-2500 µg/kg of balixafortide. Safety, tolerability, pharmacokinetics and pharmacodynamics were assessed.RESULTS: Balixafortide was well tolerated and rated favorably over G-CSF by subjects. At all doses tested balixafortide mobilized HSPC. In the dose range between 1500 and 2500 µg/kg mobilization was similar, reaching 38.2 ± 2.8 CD34 + cells/µL (mean ± SEM). Balixafortide caused mixed leukocytosis in the mid-20 K/µL range. B-lymphocytosis was more pronounced, whereas neutrophilia and monocytosis were markedly less accentuated with balixafortide compared to G-CSF. At the 24 h time point, leukocytes had largely normalized.CONCLUSIONS: Balixafortide is safe, well tolerated, and induces efficient mobilization of HSPCs in healthy male volunteers. Based on experience with current apheresis technology, the observed mobilization at doses ≥1500 µg/kg of balixafortide is predicted to yield in a single apheresis a standard dose of 4× 10E6 CD34+ cells/kg from most individuals donating for an approximately weight-matched recipient. Exploration of alternative dosing regimens may provide even higher mobilization responses.
