Galectin Therapeutics Reports Q2 2019 Financial Results and Provides Business Update

NORCROSS, Ga. (August 9, 2019) 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 three months ended June 30, 2019. 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.

Harold H. Shlevin, Ph.D., President

and Chief Executive Officer of Galectin Therapeutics, said, Over the past several months we have made significant progress advancing our proprietary compound, belapectin

(GR-MD-02) for a Phase 3 trial. After having raised approximately $44.9 million in our Rights Offering and selecting a leading global CRO with deep experience in

our therapeutic area and operations in over 60 countries as our clinical research organization (CRO), we recently submitted our Phase 3 clinical trial protocols to the FDA for comment along with a draft Phase 4 synopsis and statistical analysis

plan. In addition, we announced that Dr. Naga Chalasani and Dr. Stephen Harrison, key NASH opinion leaders, who dedicated considerable effort in the design of the study, have been designated as

co-primary investigators in the Phase 3 NASH-RX clinical trial. Consequently, we believe all of the elements to commence this important study are solidly in place.

Belapectin is the first drug to show positive results in a clinical trial in patients with compensated NASH cirrhosis without esophageal varices, and it is with great optimism that we anticipate a fourth quarter launch of this very important

The NASH-RX trial is designed as an international, multicenter, randomized, placebo-controlled,

double-blind, parallel-group, Phase 3 study with approximately 500 patients at up to 128 sites in 11 countries in North America, Europe, Asia, and Australia. The study is designed to evaluate the safety and efficacy of two doses of belapectin for

the treatment of compensated non-alcoholic steatohepatitis (NASH) cirrhosis with clinical evidence of clinically significant portal hypertension without esophageal varices. Enrollment is expected to commence

in the fourth quarter of 2019 with an estimated 12-14 months to achieve full enrollment. The treatment period for Phase 3 is two years, and topline data readout is expected around the end of 2022.

With the continued support of the medical, patient, and investment communities we are excited to be advancing this new drug toward treating the millions

of people globally with NASH cirrhosis.

Richard E. Uihlein, Chairman of the Board, added, The success of the Rights Offering, the support of

Drs. Chalasani and Harrison, execution of a start-up agreement with our CRO to accelerate time to patient enrollment, and the commitment and dedication of our employees provide Galectin with a world-class

team that can ensure the upcoming clinical trials are rigorously administered. We are all looking forward to the launch of this trial in the fourth quarter and the data it will provide about the important role belapectin may play in helping those

suffering from NASH cirrhosis.

Summary of Key Development Programs and Updates

Scientific Presentations and Conferences

For the three months ended June

30, 2019, the Company reported a net loss applicable to common stockholders of $3.1 million, or $0.06 per share, compared to a net loss applicable to common stockholders of $4.1 million, or $0.11 per share, for the three months ended

June 30, 2018. The decrease was primarily due to lower preclinical, clinical and non-cash stock-based compensation expenses in the current period compared to the prior year period.

Research and development expense for the three months ended June 30, 2019, was $1.5 million

compared with $1.5 million for the three months ended June 30, 2018. There was an increase of about $0.6 million in clinical development expenses which was offset by a similar amount of decrease in

non-cash stock-based compensation expense. General and administrative expense for the three months ended June 30, 2019, were $1.5 million, compared to $2.3 million for the three months ended

June 30, 2018, primarily due to a decrease in non-cash stock-based compensation expenses.

30, 2019, the Company had $52.0 million of cash and cash equivalents. The Company also has a $10 million unsecured line of credit, under which no borrowings have been made to date, and potential additional capital under its At the

Market common stock issuance agreement. The Company believes there is sufficient cash, including availability of the line of credit, to fund currently planned operations at least through December 31, 2020. The Company expects that it will

require more cash to fund operations after December 31, 2020 and believes it will be able to obtain additional financing as needed. The currently planned operations include estimated costs related to a planned Phase 3 clinical trial through

December 31, 2020. While the costs of the trial and general overhead during the Phase 3 trial are expected to be approximately $100 million, the costs and timing of such trial is not yet completely finalized.

About Galectin Therapeutics

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 severe atopic dermatitis, moderate-to-severe plaque psoriasis, and in 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. Additional information is available at
