On April 13, 2021 Galectin Therapeutics Inc. (NASDAQ:GALT), the leading developer of therapeutics that target galectin proteins, reported that a paper published in the peer-reviewed Journal for ImmunoTherapy of Cancer (JITC), the highest ranked fully open access immunology journal, provides 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) (Press release, Galectin Therapeutics, APR 13, 2021, View Source [SID1234578044]).

The paper, titled "Enhancing Clinical and Immunological Effects of anti-PD-1 with Belapectin, a Galectin-3 Inhibitor" (doi:10.1136/jitc-2021-002371) describes results from an ongoing Phase 1 clinical study, a collaboration between Galectin Therapeutics and Providence Cancer Institute in Portland, Oregon.

Following the recent publication of positive preclinical results that showed the inhibition of galectin-3 in combination with an agonist anti-OX40 monoclonal antibody reprograms the tumor microenvironment to favor anti-tumor activity, the current study tests the clinical hypothesis that galectin-3 blockade with belapectin in combination with pembrolizumab enhances tumor response for patients with advanced MM or HNSCC.

In the study, as previously disclosed, 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. The authors noted that the combination was associated with fewer immune-mediated adverse events than anticipated with pembrolizumab alone. In addition, the analysis of patients’ tumor tissue revealed reduced monocytic myeloid-derived suppressor cells and increased effector memory T-cell activation in responders compared with non-responders. Also, an increased baseline expression of galectin-3 positive tumor cells correlated with clinical response.

"Immunotherapy is a significant breakthrough in the treatment of many cancers, but tumor-induced immune suppression contributes to treatment resistance. Galectin-3 is an important driver of this tumor-induced immunosuppression, and this clinical study constitutes proof-of-concept that the addition of belapectin, a galectin-3 inhibitor, to a PD-1 inhibitor can benefit cancer patients," said Dr. Brendan Curti, M.D., Earle A. Chiles Research Institute, a division of Providence, and the first author of the paper.

"The analysis of patients’ tumor tissues is consistent with previously published pre-clinical data with belapectin and confirms the ability of belapectin to modulate the tumor microenvironment to favor anti-tumor activity. The possibility to improve the tolerance and safety of immunotherapy is also very exciting," commented Pol F. Boudes, M.D., Chief Medical Officer of Galectin Therapeutics. "These proof-of-concept clinical data provide a strong rationale to initiate a randomized placebo-controlled phase 2 clinical trial to evaluate the efficacy and safety of belapectin in combination with a PD-1 inhibitor compared to a PD-1 inhibitor alone in this cancer patient population. We look forward to continuing our work with Providence Cancer Institute, and we anticipate the upcoming release of additional data from the expansion cohort in this study."

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; 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.

Colorectal cancer (CRC) represents the fourth most frequent cause of brain metastasis, which is the most common brain tumor. The study included an analysis of more than 16,000 human CRC local and metastasis samples, and revealed increased amplification of IRS2 in brain metastases.

In an in vitro system mimicking the brain microenvironment, IRS2-overexpressed CRC cells showed prolonged survival. Importantly, transcriptomic analysis demonstrated significant enrichment of the oxidative phosphorylation (OXPHOS) pathway by IRS2. CRC cells expressing IRS2 showed increased mitochondrial activity and glycolysis-independent viability. Inhibition of IRS2 using NT219 dose-dependently inhibited IRS2-expressing cells viability and OXPHOS genes expression.

The Wnt/β-catenin pathway was among the most significantly enriched pathways in the brain metastasis, as IRS2-expressing cells showed increased transcriptional activity of the β-catenin. In addition, NT219 decreased the transcriptional activity of β-catenin in IRS2-expressing CRC cells to a greater extent than AKT and PI3K inhibitors, and most significantly suggested relevance of IRS2 in activating β-catenin. It was further shown that 5-FU, a chemotherapy approved for treating CRC, elevated β-catenin expression, and that NT219 diminished both 5FU-induced and the basal level of the β-catenin expression. Utilizing an intracranial animal model, it was also demonstrated that while 5-FU alone had no significant effect, the combination of 5-FU and NT219 significantly inhibited the formation of brain metastasis and extended survival rates of the study mice.

"We are excited about these highly encouraging study results," said Bertrand Liang, M.D., Ph.D., Chief Medical Officer of Purple Biotech. "These compelling data provide important insights regarding the role of IRS2 in promoting CRC brain metastasis, and suggest that novel agents such as NT219 have the potential to effectively inhibit the development of brain metastasis. Our ongoing Phase 1/2 clinical trial of NT219 as monotherapy for the treatment of solid tumors, followed by a dose escalation of NT219 in combination with cetuximab, an epithelial growth factor receptor (EGFR) blocking monoclonal antibody, for the treatment of recurrent and/or metastatic solid tumors and squamous cell carcinoma of the head and neck cancer, is proceeding with enrollment as planned and we continue to expect the availability of top-line data from the first part of this study in the second half of this year."
