Galectin-3 Is A Critical Target For Therapy of Liver Fibrosis 1. Galectin-3 is produced in large amounts by human fibrotic liver 2. Galectin-3 is essential in mice for the development of liver fibrosis 3. Galectin inhibitors block production of fibrogenic markers in the key human cell responsible for liver fibrosis 4.

Summary Of Development Program Rationale In Liver Fibrosis • Liver fibrosis represents a very large unmet medical need • Galectin-3 protein is proven target • Drugs reverse liver fibrosis in animals and show efficacy in human cell culture models of fibrosis • Non toxic drugs with little likelihood of drug interactions • Rapid clinical development pathways • Initial indication provides opportunity for orphan disease status, fast track, priority review, and potentially accelerated approval © Galectin Therapeutics OTC : GALT 16 |
Development Program & Markets • Initial Indication: Post transplant recurrent Hepatitis C with fibrosis • Focus of first phase II clinical trial • Orphan disease designation possible • Additional peri-transplant indications: • Established cirrhosis of various etiologies but not eligible for transplantation • Established cirrhosis of various etiologies, on transplant list • Expansion of indications • Non-alcoholic fatty liver disease (NASH) • Viral hepatitis C and B with fibrosis • Alcoholic fibrosis © 2011 Galectin Therapeutics OTC:GALT 17 |

Roles Of Secreted Galectins In Cancer The vast majority of cancers secrete large amounts of galectins • Galectins impact cancer growth at many points • Interfering with galectin function has been shown to have beneficial effects • Galectin Therapeutics has proprietary compounds that leverage this benefit 21 © 2011 Galectin Therapeutics OTC:GALT |
Phase 2 Clinical Trial Performed in Metastatic Colorectal Cancer (DAVFU-003) Cancer Trial (DAVFU-003) Day 0 Day 28 GM-CT-01 Chemo (5-FU) Phase 2 trial of 5-FU plus GM-CT-01 in line 3/4 therapy of metastatic colorectal cancer Twenty (20) patients enrolled who all had 3 to 4 previous courses of chemotherapy, including 5-FU and biologicals Overall median survival was 6.7 months. In similar patients, Erbitux ® had a 6.1 month survival compared to 4.6 months with no therapy Suggests efficacy of regimen |
GM-CT-01 Reduces 5-FU Chemotherapy Related Side Effects Simultaneous improved efficacy with reduction in side effects of standard chemotherapy would be desirable in cancer therapeutics Data on 5-FU+GM-CT-01 compiled from patients receiving full dose therapy in studies DAVFU-001, 003, 006, and 007 © 2011 Galectin Therapeutics OTC:GALT 23 |
Development Approach In Colorectal Cancer • Studies demonstrate potential utility of galectin inhibitors in combination with chemotherapy in cancer • FDA has confirmed that preclinical and clinical data are adequate to proceed with large clinical trials • Our colorectal cancer program remains active, but we are deferring new clinical trials pending data from the tumor immunology clinical trial that may improve the design of future studies • More rapid international registration is an approach that may provide revenue to support development programs and gain additional clinical experience with GM-CT-01 © 2011 Galectin Therapeutics OTC:GALT 24 |
Registration And Marketing GM-CT-01 In Colombia And Latin America • The government of Colombia, and oncology key opinion leaders in that country, expressed an interest in making GM-CT-01 available for use in Colombia for patients with metastatic colorectal cancer • Equally interested in the increased tumor efficacy and reduction in 5- FU related side effects • Our partner Pro-Caps has submitted a marketing application to INVIMA (FDA equivalent) and has indicated our clinical data should be sufficient for approval • With approval, Pro-Caps expects sales to begin in 2012 • Upon success in Colombia, we have the opportunity to seek approval in other Latin American countries (reciprocity with 12 other countries) © 2011 Galectin Therapeutics OTC:GALT 25 |
