Multiple Research Results from Innovent's General Biomedicine Pipeline to be Showcased at the ADA 85th Scientific Sessions

Rhea-AI Summary

Innovent Biologics (IVBIY) presented multiple research findings at the ADA 85th Scientific Sessions, showcasing two key drug candidates. IBI3030, a novel antibody-peptide conjugate, demonstrated significant improvements in cardiovascular risk markers through its multi-target approach combining PCSK9 inhibition with GLP-1R/GCGR/GIPR activation. Preclinical studies showed notable reductions in LDL-c, Lp(a), and body weight, with improved glucose tolerance. Additionally, three investigator-initiated studies of mazdutide, their dual GCG/GLP-1 receptor agonist, revealed superior efficacy compared to semaglutide in reducing liver fat accumulation, alleviating MASH and hepatic fibrosis, and lowering serum uric acid levels through enhanced fatty acid oxidation and metabolic regulation.

IBI3030 is a novel anti-PCSK9 antibody conjugated with peptides targeting GLP-1R, GCGR, and GIPR. Through multi-target synergistic effects, it significantly improves cardiovascular metabolic risk indicators. Mechanistically, the anti-PCSK9 antibody component inhibits LDL receptor degradation, thereby lowering reduce plasma LDL-c levels. Simultaneously, the triple-target agonist peptide activates GLP-1R/GCGR/GIPR receptors, enhancing hepatic fatty acid oxidation capacity, with demonstrates superior efficacy compared to the control. Preclinical studies demonstrate that in multiple models (mice, rats, and non-human primates), IBI3030 significantly reduces LDL-c (p<0.01 vs. baseline) and Lp(a), improves oral glucose tolerance (OGTT) (effective even in GLP-1R knockout mice), reduces body weight, and preserves insulin sensitivity. Additionally, it exhibits excellent safety in non-human primates, with a maximum tolerated dose reaching 50 mg/kg.

Furthermore, mazdutide, the fastest-developing dual glucagon (GCG)/glucagon-like peptide-1 (GLP-1) receptor agonist globally, has ignited significant research interest in the scientific community due to its comprehensive metabolic benefits. This year's ADA Annual Meeting featured multiple MoA studies on mazdutide's effects in reducing liver fat, improving fibrosis, and lowering serum uric acid. The following are investigator-initiated studies:

Topic: The Dual Glucagon and Glucagon-Like Peptide 1 Receptor Agonist Mazdutide Outbalanced Glucagon-Like Peptide 1 Receptor Agonist Semaglutide Monotherapy in Improving Mice Liver Fat Accumulation

Liver RNA-sequencing and KEGG enrichment analysis showed that compared with Semaglutide treatment, Mazdutide treatment predominantly activated oxidative phosphorylation and fatty acid degradation pathways. Meanwhile, lipid metabolism-related genes were upregulated in Mazdutide group compared to Semaglutide group. We further screened differentially expressed transcription factors (TF) through the TRRUST database and found that activating transcription factor 3 (Atf3) upregulated in the Mazdutide treatment group might be the functional TF regulating lipid degradation in the liver. The dual GCGR/GLP-1R agonist mazdutide exhibited a better efficacy in weight loss and liver fat accumulation alleviation compared with the GLP-1R agonist semaglutide monotherapy potentially due to its promotion of fatty acid oxidation via transcription factor ATF3.

Topic: Mazdutide，a GCG/GLP-1R dual-agonist, alleviates MASH and hepatic fibrosis
Abstract Number: 1616-P

With the mice presented NASH and fibrosis phenotypes, Mazdutide decreased body weight, liver weight and hepatic triglyceride levels. Notably, Mazdutide also mitigated hepatic fat accumulation, inflammation, and hepatic fibrosis, compared with a single GLP1R or GCGR agonist. Therefore, Mazdutide alleviates hepatic fibrosis in MASH mice and regulates lipid metabolism as well as the gut microbiota, which may contribute to providing a novel therapeutic method and therapeutic target for MASH

Topic: Mazdutide, a Dual GLP-1R/GCGR Agonist, Alleviates Hyperuricemia by Modulating Hepatic Energy and Lipid Metabolism and Inhibiting Purine Pathways
Abstract Number: 775-P

Mazdutide significantly lowers serum uric acid levels in hyperuricemic rats, primarily by enhancing fatty acid oxidation and regulating cellular energy metabolism within hepatocytes. This process suppresses the expression of genes associated with glucose and purine metabolism in the liver, leading to a reduction in the generation and utilization of purine precursors. SnRNA-Seq analysis indicates that mazdutide increases the expression of GCGR in hepatocytes, whereas semaglutide slightly inhibits it. In hyperuricemic rats, the expression of key genes involved in fatty acid oxidation, such as Cpt1a, Fabp1, Apoa1, Acox1, and Acaa1a is significantly reduced. However following Mazdutide treatment, the expression of these genes markedly increases, promoting fatty acid oxidation and improving overall energy metabolism. In contrast, genes associated with fatty acid synthesis, such as Acaca and Fasn, show a significant reduction in expression. Furthermore, after Mazdutide intervention, the expression of genes related to glucose metabolism and purine metabolism, including Pklr, G6pc1, Glul, Gckr, Gk, Nt5e, and Ppat, also experience significant decreases. This shift may reflect a change in cellular metabolism towards more efficient fatty acid oxidation, resulting in reduced the generation and utilization of purine precursors. Compared to Semaglutide, Mazdutide offers more substantial benefits in lowering uric acid levels.

Dr. Lei Qian from Innovent Biologics, stated, "We are delighted to see mazdutide's mechanism exploration studies featured extensively at the ADA conference. The growing body of scientific evidence will further validate mazdutide's differentiated profile as a next-generation GCG/GLP-1 dual receptor agonist, particularly in liver fat and serum urine reduction. Moreover, in the field of cardiovascular and metabolic diseases, Innovent is dedicated to developing next-generation innovative therapies. This includes IBI3030 (PCSK9-GGG), a novel modality with a unique MoA that embodies an innovative 'one-drug, multiple-effects' therapeutic strategy. IBI3030 has the potential to deliver comprehensive therapeutic benefits and meaningfully improve outcomes for more patients worldwide."

About Mazdutide (IBI362)

Innovent entered into an exclusive license agreement with Eli Lilly and Company (Lilly) for the development and potential commercialization of mazdutide, a GLP-1R and GCGR dual agonist, in China. As a mammalian oxyntomodulin (OXM) analogue, mazdutide may offer additional benefits beyond those of GLP-1 receptor agonists—such as promoting insulin secretion, lowering blood glucose and reducing body weight—by also activating the glucagon receptor to increase energy expenditure and improve hepatic fat metabolism. Mazdutide has demonstrated excellent weight loss and glucose-lowering effects in clinical studies. It has also shown benefits in reducing waist circumference, blood lipids, blood pressure, blood uric acid, liver enzymes, and liver fat content, as well as improving insulin sensitivity.

Currently, Mazdutide has two NDAs accepted for review by NMPA, including for:

• Long-term weight management in adults with obesity or overweight.
• Glycemic control in adults with type 2 diabetes (T2D).

Mazdutide is currently being evaluated in seven Phase 3 clinical studies, including:

• GLORY-1: A Phase 3 trial in Chinese participants with overweight or obesity.
• GLORY-2: A Phase 3 trial in Chinese participants with moderate-to-severe obesity.
• GLORY-3: A Phase 3 trial comparing mazdutide and semaglutide in Chinese participants with overweight/obesity and metabolic dysfunction-associated fatty liver disease (MAFLD).
• GLORY-OSA: A Phase 3 trial in Chinese participants with obstructive sleep apnea (OSA) and obesity.
• DREAMS-1: A Phase 3 trial in treatment-naïve Chinese participants with T2D.
• DREAMS-2: A Phase 3 trial comparing mazdutide and dulaglutide in Chinese T2D participants with inadequate glycemic control on oral antidiabetic drugs.
• DREAMS-3: A Phase 3 trial comparing mazdutide and semaglutide in Chinese participants with T2D and obesity.

Among these, GLORY-1, DREAMS-1, and DREAMS-2 have already met their primary endpoints and the other four studies are currently ongoing.

In addition, several new clinical studies of mazdutide are initiated or planned, including:

• A Phase 3 trial in adolescents with obesity.
• New studies in metabolic dysfunction-associated steatohepatitis (MASH) and heart failure with preserved ejection fraction (HFpEF).
