(Nasdaq: ALT), a clinical-stage biopharmaceutical company, today presented data on the effect of pemvidutide, its GLP-1/glucagon dual receptor agonist candidate in development for obesity and metabolic dysfunction-associated steatohepatitis (MASH), on cardioinflammatory lipids at the American Diabetes Association’s (ADA) 84th Scientific Sessions. “Dyslipidemia is one of the most significant co-morbidities of obesity, impacting up to 70% of patients with obesity,” said Vipin K. Garg, Ph.D., President and Chief Executive Officer of Altimmune. “These data add to the differentiated profile of pemvidutide and reinforce its potential to reduce inflammatory lipids associated with cardiovascular plaque formation and cardiovascular risk in patients with obesity.” Dysregulated lipid profiles in obesity can cause systemic inflammation and elevate cardiovascular disease (CVD) risk. To better understand the potential impact of pemvidutide on lipoprotein and glycoprotein biomarkers of CVD inflammation, samples were analyzed from the 12-week, randomized placebo-controlled Phase 1 study of pemvidutide in subjects with overweight or obesity but not type 2 diabetes. In the study, 34 subjects were randomly assigned 1:1:1:1 to pemvidutide (1.2mg, 1.8mg and 2.4mg) or placebo administered once-weekly subcutaneously for 12 weeks. Lipidomic, lipoparticle and glycoprotein profiling was conducted using ultra-high performance liquid chromatography-mass spectrometry and proton nuclear magnetic resonance on plasma samples at baseline and after 12 weeks of treatment. Serum lipids including total cholesterol, low density lipoprotein cholesterol (LDL-C), and triglycerides were reduced by 28%, 26% and 38% respectively. The reductions in each class of these lipids were not correlated with weight loss, suggesting that lipid effects were due to the direct impact of pemvidutide on lipid metabolism. A detailed analysis showed pemvidutide significantly reduced small dense LDL-C, short-chain diglycerides with higher degree of saturation, lysophosphatidylinositols, lysophosphatidylcholines and sphingolipids, all lipids with a strong association with...
