Galactic-1: A Randomized, Double-Blind, Multicentre, Parallel, Placebo-Controlled Phase 2b Study in Subjects with Idiopathic Pulmonary Fibrosis (IPF) Investigating the Efficacy and Safety of TD139, an Inhaled Galectin-3 Inhibitor Administered via a Dry Powder Inhaler Over 52 Weeks (PENNSYLVANIA CONVENTION CENTER, Hall D-E (200 Level), Area J) - Mar 15, 2020 - Abstract #ATS2020ATS_6339; This study represents the first Phase 2b study with an inhaled therapy. With the favourable toxicity profile and biomarker changes observed in the initial FIH studies and the unique pharmacological profile with proven target engagement in the lung, TD139 promises to be an exciting novel therapy for IPF.

Discovery of GB1211, the first orally available galectin/galectin-3 inhibitor to be taken into clinic studies as a potential treatment for organ fibrosis (Grand Ballroom B, Pennsylvania Convention Center) - Feb 13, 2020 - Abstract #ACSSp2020ACS_Sp_15928; This compound recently entered Phase IIb trials after a successful phase I/IIa trial, where TD139 demonstrated a significant effect on biomarkers associated with IPF progression. We herein present a new series of high affinity and orally available galectin-3 inhibitors.[5] This lecture will discuss the pharmacology of galectin- 3 and the discovery process leading up to selection of GB1211, the first orally available galectin inhibitor taken to clinical studies, GB1211, and the progress of this molecule in the clinic to date.

Galectin-3 Promotes CXCR2 Expression in Medulloblastoma (Ballroom Lawn) - Oct 29, 2019 - Abstract #SNO2019SNO_1219; Among the Gal family, Gal-3 in particular was highly expressed in MB tumor slices. To further investigate Gal-3's role in the pathophysiology of MB, we used either small interfering RNA (siRNA) to knock down Gal-3 expression or Gal-3 inhibitor, TD139 to suppress Gal-3 expression in ex vivo slice culture model...These results indicate that highly expressed Gal-3 may up-regulate CXCR2 to augment MB invasiveness and progression. Gal-3 may be a prognostic and innovative target for the treatment of MB.

Galectin-3 as a Potential Therapeutic Target in Recurrent Atypical and Malignant Meningioma (Ballroom Lawn) - Oct 29, 2019 - Abstract #SNO2019SNO_1065; Furthermore, we demonstrated that TD139 inhibits MM growth in an in vivo xenograft MM model. Taken together, our results suggest that Gal-3 modulates uPAR expression and that Gal-3 may be a potential therapeutic target for the treatment of atypical and malignant meningiomas.
