Positive Findings From Phase 1b Trial of GlycoMimetics’ GMI-1359 To Be Presented at AACR 2021 Meeting
- Preclinical research included in poster supports clinical findings and demonstrates enhanced immune response in metastatic breast carcinoma model
The initial data from the study confirmed the dual CXCR4 and E-selectin antagonist’s on-target effects. In the two patients who completed treatment, evaluations of peripheral blood showed a consistent mobilization of CD34+ hematopoietic stem and progenitor cells at doses beginning at 5 mg/kg and a reduction of plasma levels of soluble E-selectin. Furthermore, in one individual, following the administration of 7.0 mg/kg of GMI-1359, an immunophenotyping assessment of peripheral blood showed a redistribution of myeloid derived suppressor cells (MDSCs) as evidenced by increased percentages of both the monocytic and granulocytic MDSCs. In this same individual following administration of 7.0 mg/kg GMI-1359, the incidence of M1 proinflammatory macrophages increased while the M2 anti-inflammatory macrophages, often associated with tumor progression, decreased. The clinical poster concludes that GMI-1359 demonstrated an acceptable safety and tolerability profile in the patients treated to date. No dose limiting toxicities were observed following multiple dose administration up to 7 mg/kg.

Title: Development of GMI-1359, a novel agent targeting tumor-microenvironment cross-talk in bone metastatic cancer
Date and Time:
GMI-1359 is designed to simultaneously inhibit both E-selectin and CXCR4, which are adhesion molecules involved in tumor trafficking and metastatic spread. Preclinical studies indicate that targeting both E-selectin and CXCR4 with a single compound could improve efficacy in the treatment of cancers that involve the bone marrow, such as AML and multiple myeloma, or in solid tumors that metastasize to the bone, such as prostate cancer and breast cancer, as well as in osteosarcoma, a rare pediatric tumor affecting about 900 adolescents a year in
