Continued Favorable Developments in both NAVIGATE and Cancer Combination Immunotherapy Trials

NORCROSS, Ga., May 17, 2021 (GLOBE NEWSWIRE) -- Galectin Therapeutics Inc. (NASDAQ: GALT), the leading developer of therapeutics that target galectin proteins, today reported financial results and provided a business update for the quarter ended March 31, 2021. These results are included in the Company's Quarterly Report on Form 10-Q, which has been filed with the U.S. Securities and Exchange Commission and is available at www.sec.gov.

Joel Lewis, Chief Executive Officer and President of Galectin Therapeutics, said, “The start to the new year has been an exciting and productive time for Galectin Therapeutics in both our NAVIGATE Phase 2b/3 clinical trial in NASH cirrhosis as well as the cancer, combination immunotherapy trial being conducted in collaboration with the Providence Cancer Institute in Portland, Oregon. In addition, since the beginning of the year, we have raised fresh capital and brought on Dr. Ben Carson, Sr., a world-renowned physician and former Secretary of Housing and Urban Development, as a special consultant. We very much look forward to working with Dr. Carson.

“In support of our innovative NAVIGATE study,” continued Lewis, “we launched NAVIGATEnash.com, a new information resource about NASH cirrhosis for both patients and physicians. NASH cirrhosis is still largely overlooked and remains a major unmet medical need. I’ve been deeply moved by the determination of this community of NASH cirrhosis patients and the physicians who treat them.

“In our cancer, combination immunotherapy trial, results of the Phase 1 trial were published in the highest ranked fully open access peer-reviewed immunology journal. The study suggests combination therapy with belapectin results in a better objective response rate with fewer adverse events than pembrolizumab (KEYTRUDA^®) alone. Brendan Curti, M.D., the first author of the paper, noted galectin-3 is an important driver of tumor-induced immunosuppression. This clinical study constitutes proof-of-concept that the addition of our galectin-3 inhibitor, belapectin, to a PD-1 inhibitor can benefit cancer patients.

“Of course,” concluded Lewis, “I would be remiss if I did not thank our Chairman, Mr. Richard Uihlein, who continues to demonstrate his strong support and provided additional funding to help advance our NAVIGATE trial, and for which we are deeply grateful.”

Richard E. Uihlein, Chairman of the Board, added, “This quarter has been an important one for Galectin Therapeutics, and having Dr. Ben Carson on our team is an investment in the future. The progress being made in both our NASH cirrhosis study and our collaboration on cancer immunotherapy demonstrates the important science behind what we are doing. Galectin-3 is involved in a wide range of human diseases, and my recent investment in the company underscores my commitment to develop belapectin to its full potential.”

Dr. Ben Carson, Sr., Engaged as Special Consultant

• Engaged Ben Carson, Sr., M.D., a world-renowned neurosurgeon and the 17th Secretary of the U.S. Department of Housing and Urban Development, as a special consultant to assist with development of the Company’s galectin-3 inhibitor, belapectin, as a treatment for NASH cirrhosis and in combination with immunotherapy for the treatment of cancers. In particular, Dr. Carson will help increase awareness of Galectin Therapeutics including our ongoing Phase 2b/3 NAVIGATE clinical trial in NASH cirrhosis, our continuing research in combination with cancer immunotherapy, and its potential in addressing other fibrotic diseases. Dr. Carson will also assist in the formation of a scientific advisory committee for the Company, recruit potential members of the committee, and identify potential strategic commercial and/or academic partners for the Company.
  

Recent Financings

• Raised $10 million in a convertible debt financing with Richard E. Uihlein, the Company’s Chairman and largest individual stockholder. The debt is unsecured and bears interest at a rate of 2% compounded annually. Additional interest of 2.5% per quarter will accrue but will only be paid if the debt and interest are converted into shares of the Company’s common stock, at Mr. Uihlein’s option, on or prior to maturity, which is four years from the date of the loan. The conversion price of the debt and interest is fixed at $5.00 per share of common stock.
  

NAVIGATE Trial Update

• Launched NAVIGATEnash.com, a trial website dedicated to educating patients and physicians about liver cirrhosis resulting from non-alcoholic steatohepatitis (NASH) as well as support NAVIGATE, the Company’s innovative, seamless adaptive Phase 2b/3 study in NASH cirrhosis.
  
  
• Galectin Therapeutics continues to actively recruit patients into NAVIGATE, its seamless, adaptive Phase 2b/3 study of belapectin for the prevention of esophageal varices in NASH cirrhosis.
  

Peer-reviewed publications, Scientific Presentations and Conferences

• Published in the Journal for ImmunoTherapy of Cancer (JITC), the highest ranked fully open access immunology journal, a peer-reviewed paper entitled, “Enhancing Clinical and Immunological Effects of anti-PD-1 with Belapectin, a Galectin-3 Inhibitor” (doi:10.1136/jitc-2021-002371), provided further clinical evidence that using belapectin, a potent galectin-3 inhibitor, in combination with pembrolizumab (KEYTRUDA^®), a PD-1 inhibitor, significantly enhances tumor response to immunotherapy in patients with advanced metastatic melanoma (MM) and head and neck squamous cell carcinoma (HNSCC). The paper describes results from an ongoing Phase 1 clinical study, a collaboration between Galectin Therapeutics and Providence Cancer Institute in Portland, Oregon. An objective response was observed in 50% of MM (7/14) and 33% of HNSCC (2/6) patients. This compares favorably to published response rates on pembrolizumab alone.
  
  
• At the 4th Global NASH Congress, which took place virtually on April 29, 2021,  Pol F. Boudes, M.D., Chief Medical Officer, reviewed Galectin Therapeutics’ scientific and clinical activities in NASH cirrhosis in a presentation entitled, “An innovative clinical development program: belapectin for NASH cirrhosis.”
  

Financial Results

For the three months ended March 31, 2021, the Company reported a net loss applicable to common stockholders of $6.3 million, or ($0.11) per share, compared to a net loss applicable to common stockholders of $3.6 million, or ($0.06) per share for the three months ended March 31, 2020. The increase is largely due an increase in 2021 research and development expenses related to the Company’s NAVIGATE trial.

Research and development expense for the three months ended March 31, 2021, was $4.9 million compared with $2.1 million for the three months ended March 31, 2020. The increase was primarily due to costs related to our NAVIGATE clinical trial and other supportive activities. General and administrative expenses for the three months ended March 31, 2021, were $1.4 million, compared to $1.4 million for the three months ended March 31, 2020.

As of March 31, 2021, the Company had $20.8 million of cash and cash equivalents. On April 16, 2021, the Company received $10,000,000 in proceeds from an unsecured convertible promissory note from its Board Chairman, Richard E. Uihlein. The Company also has a $10 million unsecured line of credit, under which no borrowings have been made to date. The Company believes it has sufficient cash, including availability under the line of credit, to fund currently planned operations and research and development activities through at least September 30, 2022.

The Company expects that it will require more cash to fund operations after September 30, 2022 and believes it will be able to obtain additional financing as needed. Currently, we expect to require an additional approximately $35-$40 million to cover costs of the trial to reach the planned interim analysis estimated to occur in the second half of 2023 along with drug manufacturing and other scientific support activities and general and administrative costs. However, there can be no assurance that we will be successful in obtaining such new financing or, if available, that such financing will be on terms favorable to us.

About Belapectin (GR-MD-02)

Belapectin (GR-MD-02) is a complex carbohydrate drug that targets galectin-3, a critical protein in the pathogenesis of NASH and fibrosis. Galectin-3 plays a major role in diseases that involve scarring of organs including fibrotic disorders of the liver, lung, kidney, heart and vascular system. Belapectin binds to galectin-3 and disrupts its function. Preclinical data in animals have shown that belapectin has robust treatment effects in reversing liver fibrosis and cirrhosis. A Phase 2 study showed belapectin may prevent the development of esophageal varices in NASH cirrhosis, and these results provide the basis for the conduct of the NAVIGATE trial. The NAVIGATE trial (NAVIGATEnash.com), entitled “A Seamless Adaptive Phase 2b/3, Double-Blind, Randomized, Placebo-controlled Multicenter, International Study Evaluating the Efficacy and Safety of Belapectin (GR-MD-02) for the Prevention of Esophageal Varices in NASH Cirrhosis” began enrolling patients in June, 2020, and is posted on www.clinicaltrials.gov (NCT04365868). Galectin-3 also has a significant role in cancer, and the Company is supporting a Phase 1 study in combined immunotherapy of belapectin and KEYTRUDA^® in treatment of advanced melanoma and in head and neck cancer.

About Fatty Liver Disease with Advanced Fibrosis and Cirrhosis

Non-alcoholic steatohepatitis (NASH) has become a common disease of the liver with the rise in obesity and other metabolic diseases. NASH is estimated to affect up to 28 million people in the U.S. It is characterized by the presence of excess fat in the liver along with inflammation and hepatocyte damage (ballooning) in people who consume little or no alcohol. Over time, patients with NASH can develop excessive fibrosis, or scarring of the liver, and ultimately liver cirrhosis. It is estimated that as many as 1 to 2 million individuals in the U.S. will develop cirrhosis as a result of NASH, for which liver transplantation is the only curative treatment available. Approximately 8,890 liver transplants are performed annually in the U.S. There are no drug therapies approved for the treatment of liver fibrosis or cirrhosis.

About Galectin Therapeutics

Galectin Therapeutics is dedicated to developing novel therapies to improve the lives of patients with chronic liver disease and cancer. Galectin’s lead drug belapectin (formerly known as GR-MD-02) is a carbohydrate-based drug that inhibits the galectin-3 protein which is directly involved in multiple inflammatory, fibrotic, and malignant diseases, for which it has Fast Track designation by the U.S. Food and Drug Administration. The lead development program is in non-alcoholic steatohepatitis (NASH) with cirrhosis, the most advanced form of NASH-related fibrosis. This is the most common liver disease and one of the largest drug development opportunities available today. Additional development programs are in treatment of combination immunotherapy for advanced melanoma and other malignancies. Advancement of these additional clinical programs is largely dependent on finding a suitable partner. Galectin seeks to leverage extensive scientific and development expertise as well as established relationships with external sources to achieve cost-effective and efficient development.
