Rewiring PD-1/PD-L1 combination therapy via glyco-immune targeting of galectins: Toward clinical translation.
(PubMed, Biochim Biophys Acta Rev Cancer)
- "Several galectin inhibitors (e.g., GR-MD-02, GB1211, LYT-200) are under clinical evaluation. Early trials showing encouraging efficacy-toxicity profiles and some combinations received FDA Fast Track designations. This review summarizes mechanistic and clinical advances and highlights their translational implications for galectin-targeted combination therapies."

Binding free energy analysis of galectin-3 natural ligands and synthetic inhibitors.
(PubMed, Protein Sci)
- "Synthetic drug molecules GB0139, GB1107, and GB1211 were estimated to have binding free energies of -4.3, -6.7, and -9.5 kcal/mol respectively. We find that while the hydroxyl groups of the natural ligands interact reasonably well with residues in galectin-3's binding pocket, structural dynamics weaken the binding pose and favor interactions with water, sometimes yielding to dissociation. In contrast, the more favorable binding energy of GB1211, leading inhibitor in clinical studies, is associated with strong and constant electric fields across the bonds investigated, suggesting a stiffer binding pose with a stabilizing σ-hole interaction."

Development and Characterization of a High-Affinity Selective Galectin-3 Mouse Tool Compound in Mouse Models of Cancer.
(PubMed, J Med Chem)
- "The first orally available galectin-3 inhibitor, GB1211 (h-galectin-3 Kd = 0.025 μM), is currently in phase 2 clinical trials...To better support translation into clinical studies, a new improved mouse galectin-3 tool compound, GB2095, was developed. Dosing this new compound in in vivo syngeneic mouse models of cancer resulted in reduction of the growth of breast and melanoma cancers."

Galecto Completes Strategic Review to Focus on Oncology and Liver Disease and Acquires Acute Myeloid Leukemia Preclinical Asset from Bridge Medicines
(GlobeNewswire)
- "Galecto, Inc...announced that, following an intensive strategic review process, Galecto has determined to focus on cancer and liver disease, leveraging its existing clinical stage asset GB1211, which has shown positive results in non-small cell lung cancer (NSCLC) and decompensated cirrhosis clinical studies. Galecto further announced that it has bolstered its pipeline with the acquisition of the global rights to BRM-1420, a novel, first-in-class asset developed by Bridge Medicines, a company co-founded by Takeda...As consideration for the acquisition of the global rights of BRM-1420, Galecto issued 62,594 shares of common stock to Bridge Medicines...As part of the strategic alternative review process, Galecto has determined not to further advance GB2064, its LOXL-2 inhibitor candidate, at this time....Galecto plans to file an IND for BRM-1420 in the US in late 2025 or early 2026 and initiate clinical studies in patients with AML thereafter."
