Galectin proteins’ ability to dimerize creates the opportunity for galectins to link glycoproteins and form a lattice structure on the cellular surface and to promote cell-cell and cell-matrix interactions Galectin-3 expression is up-regulated in established human fibrotic liver disease, and disruption of Galectin-3 can markedly reduce liver fibrosis (*) * Source: Henderson et al., PNAS, 2006. Central role of Gal-3 in multiple pathological processes Belapectin targets and disrupts the function of galectin-3, which plays a major role in the progression of fibrotic diseases

Slide 15

Portal hypertension is a deleterious consequence of cirrhosis and responsible for the majority of cirrhotic complications Portal pressure of ≥10 mmHg (HVPG) is associated with increased risk of decompensation and mortality The increase in portal pressure and the development of varices are a continuum of the same mechanism of action For patients with portal hypertension who have not yet developed varices, there are no specific therapies available Beta-blockers likely do not prevent development of varices/disease progression in early-stage cirrhosis patients (may improve outcomes in patients with portal hypertension and varices) Practice guidelines do not recommend beta-blockers for the prevention of esophageal varice No specific therapy to address fibrosis at the cirrhotic stage Belapectin was safe and well tolerated in NASH-CX, at doses up to 8 mg/kg LBM The NASH-CX study provided a proof of concept for efficacy and for selecting the prevention of esophageal varices as a primary outcome to move forward Belapectin demonstrated efficacy on a clinically meaningful endpoint where no current therapies exist

NASH cirrhosis Patients with NASH cirrhosis have the greatest immediate medical need This population is not being addressed by most drug developers, who focus on the prevention of NASH cirrhosis using liver biopsies as an efficacy endpoint An innovative seamless, adaptive Phase 2b/3 developed with leading NASH experts Progression to varices is a potential surrogate endpoint Progression to large varices is a component of a composite clinical endpoint Upper GI endoscopies are part of routine clinical practice to follow cirrhotic patients NASH cirrhosis patients with portal hypertension are at risk of developing esophageal varices which may bleed and are then life-threatening It is possible to identify portal hypertension clinically without having to perform invasive hemodynamic studies Dedicated trial website for physicians and patients. www.NAVIGATEnash.com NAVIGATE Overview: Adaptively Designed Phase 2b/3 Study

Belapectin activity demonstrated in tumor-bearing mice models (sarcoma, mammary carcinoma, and prostate adenocarcinoma)1 Belapectin good tolerance, apparent safety, and efficacy demonstrated in a phase 1 study2 and a phase 1 extension study in metastatic melanoma (MM) and head and neck squamous cell carcinoma (HNSCC): Prof Brendan Curti3 (Portland, OR): investigator-sponsored IND in collaboration with Galectin Therapeutics. Belapectin used in combination with anti-PD-1 (Keytruda®, pembrolizumab). Objective response observed in 50% of MM (7/14) and 33% of HNSCC (2/6) patients. Extension in more advanced patients: 56% stable disease in MM (5/9) and 40%in HNSCC (2/5). Combination is associated with fewer immune adverse events than expected. Combination shows good tolerance and appears safe with no dose-limiting toxicity. Combination significantly increases effector memory T-cell activation and reduces M-MDSCs in responders vs. non-responders. Increased baseline expression of Gal3+ tumor cells and PD-1+CD8+ T cells in the periphery and higher serum trough levels of pembrolizumab correlate with clinical response. Conclusion: Clinical efficacy and safety proof of concept in combination with PD-1 inhibitor achieved. Phase 2 study in planning stage. Belapectin Oncology Data Overview 1 Sturgill ER et al.

Extension cohort showed positive results in partial response or stable disease (56% in 5 of 9 melanoma patients and 40% in 2 of 5 head and neck patients). The frequency and severity of toxicities related to pembrolizumab, notably immune-mediated adverse events, was less than anticipated Potential to improve efficacy and safety of cancer immunotherapy Plans for Phase 2 combination trial to be finalized.
