• Late-breaking oral and poster presentations include clinical and preclinical data related to GULLIVER-2 clinical trial

BOSTON, Oct. 31, 2022 (GLOBE NEWSWIRE) -- Galecto, Inc. (NASDAQ: GLTO), a clinical-stage biotechnology company and a world leader in galectin biology focused on the development of novel treatments for fibrosis and cancer, today announced it will present data from its recently completed Phase 1b/2a GULLIVER-2 trial at the American Association for the Study of Liver Diseases’ (AASLD) The Liver Meeting 2022 being held in Washington, D.C. on November 4-8, 2022. GULLIVER-2 is a clinical trial designed to assess GB1211, an orally available and high-affinity small molecule carbohydrate-based galectin-3 inhibitor, for the treatment of severe liver diseases. Galectin-3 is a pro-fibrotic β-galactoside binding protein highly expressed in fibrotic livers and implicated in severe liver diseases.

In a late-breaking oral presentation, which was selected as Best of the Liver Meeting in the NASH/NAFLD category, Galecto will present topline data from Part 2 of its GULLIVER-2 trial (NCT05009680), an innovative, hybrid-design 3-part study investigating the safety, pharmacokinetics (PK), and exploratory efficacy of GB1211 in patients with decompensated cirrhosis. In this study, GB1211 was well-tolerated, had a predictable PK profile and showed encouraging signs of clinical efficacy (liver laboratory tests and FibroScan®). The observed reductions of liver enzyme values and measurements of liver fat indicate a decrease of liver inflammation and underlying steatosis, respectively. Overall, the data suggests a positive therapeutic effect in severe cirrhosis. This trial offers strong support for further development of GB1211 in severe liver diseases.

Additional information and further analysis of these data relating to the GULLIVER-2 Part 2 trial findings will also be discussed in a webinar hosted by Galecto on Monday, November 8^th at 8 a.m. ET.

In a separate poster presentation, Galecto will highlight findings from Parts 1 and 3 of the GULLIVER-2 trial, where preliminary data indicates that liver impairment had moderate effects on the GB1211 PK profile compared to healthy participants. In patients with decompensated cirrhosis, GB1211 was observed to be well-tolerated with no treatment-related adverse events, supporting that it can be orally administered to patients with moderate and severe liver impairment in future trials.

In support of the clinical data to be presented at The Liver Meeting 2022, Galecto will also present a late-breaking preclinical poster demonstrating GB1211’s ability to inhibit galectin-3 in severe liver diseases. In this study, the efficacy of GB1211 was investigated in a high fat diet rabbit model of non-alcoholic steatohepatitis (NASH)/fibrosis. GB1211 significantly reduced all measures of inflammation, fibrosis and fat compared to the control group. There were also trends for reduction in fibrotic and galectin-3 mechanistic genes (COL1A1, COL3A1, SNAI2, LGALS3, PAI-1), indicating positive effects of galectin-3 inhibition.

“With no approved disease-modifying treatments for decompensated cirrhosis, overall survival rates are poor with a median survival of approximately two years,” said Bertil Lindmark, M.D., Ph.D., Galecto’s Chief Medical Officer. “There is a critical need for new treatment options for severe liver diseases and related complications, including liver cancer. Our presentations at The Liver Meeting demonstrate GB1211’s potential to provide hope to patients living with severe liver diseases.”

About Liver Disease
Liver diseases, including liver fibrosis or cirrhosis, are a global health burden. Cirrhosis – primarily caused by non-alcoholic steatohepatitis, alcoholic liver disease and hepatitis – is the end stage of progressive liver fibrosis and the leading cause of liver-related death globally.

About the GULLIVER-2 Trial
The GULLIVER-2 trial (NCT05009680) is a Phase 1b/2a trial designed to assess the safety, tolerability, pharmacokinetics and potential activity of GB1211 in up to 54 participants. This study includes patients with decompensated cirrhosis (Child-Pugh Classes B and C). The study consists of three separate parts.

Parts 1 and 3 of the GULLIVER-2 trial are open-label, single dose study parts designed to evaluate the safety and pharmacokinetics of GB1211 in patients with moderate to severe hepatic impairment (Child-Pugh B and C, respectively) and compare with matched healthy subjects.

Part 2 of the GULLIVER-2 trial is a Phase 2, randomized, double-blind, placebo-controlled trial in 30 patients that is designed to assess the effect of 12-week repeated dosing of oral GB1211 in patients with decompensated cirrhosis (Child-Pugh B). Patients are randomized 1:1 to receive oral GB1211 100mg or placebo twice daily for 12 weeks.

About GB1211
Galecto is developing GB1211, an orally available and potent small molecule galectin-3 inhibitor. Galecto’s initial target indications for GB1211 are liver cirrhosis, a severe, progressive disease that ultimately leads to liver failure, and non-small cell lung cancer, a cancer indication with a high unmet medical need.

GB1211 demonstrated antifibrotic activity and anti-cancer effects in multiple preclinical models and has successfully completed a Phase 1 trial in 78 healthy volunteers. In the Phase 1 trial, GB1211 had a favorable tolerability profile and exhibited dose-dependent pharmacokinetics.

About Galecto
Galecto is a clinical stage company incorporated in the U.S. that is developing small molecule-based inhibitors of galectin-3 and LOXL2. Galecto has four ongoing Phase 2 clinical programs in fibrosis and cancer, including (i) an inhaled galectin-3 modulator (GB0139) in a Phase 2b trial for the treatment of idiopathic pulmonary fibrosis (IPF); (ii) an orally active LOXL2 inhibitor (GB2064) in a Phase 2 trial for the treatment of myelofibrosis; (iii) an orally active galectin-3 inhibitor (GB1211) in a Phase 1b/2a trial in liver cirrhosis; and (iv) an orally active galectin-3 inhibitor (GB1211) in a separate Phase 2 trial for the treatment of non-small cell lung cancer (NSCLC) in combination with atezolizumab (Tecentriq®).
