Novo Nordisk to present Wegovy® and Ozempic® data showing life-saving cardiovascular benefits for people living with obesity and type 2 diabetes at the European Society of Cardiology Congress 2025
GlobeNewswire News Room· 2025-08-20 13:31
Core Insights - Novo Nordisk announced new data on the cardiovascular protective benefits of Wegovy® and Ozempic® to be presented at the ESC Congress 2025, highlighting the role of inflammation in atherosclerotic cardiovascular disease (ASCVD) [1][3] Group 1: Cardiovascular Benefits - Semaglutide has been shown to reduce the risk of cardiovascular events by 20-26%, leading to fewer hospitalizations, heart attacks, strokes, and deaths for individuals with diabetes and obesity [2] - The unique benefits of semaglutide on heart and kidney disease will be substantiated through both clinical trials and real-world evidence at the ESC Congress [4] Group 2: Scientific Presentations - Key presentations will include data on Ozempic® (1.0 mg), Rybelsus® (oral semaglutide), and Wegovy® (2.4 mg), focusing on their impact on conditions like atrial fibrillation and cardiometabolic benefits in type 2 diabetes [5][6] - Specific sessions will address the effects of semaglutide on heart failure outcomes, cardiovascular risk factors, and the relationship between inflammation and cardiovascular events [6][13] Group 3: Research and Evidence - Real-world evidence will be presented to analyze the impact of inflammation on mortality and major cardiovascular events in individuals with ASCVD [3][5] - The role of systemic inflammation in cardiovascular disease and chronic kidney disease will be explored through various studies and analyses during the congress [13][19]
Lexaria's DehydraTECH-Liraglutide Human GLP-1 Clinical Study Supports Pathway to Potential FDA Registration as an Orally-Delivered Capsule
Thenewswire· 2025-06-11 13:05
Core Insights - Lexaria Bioscience Corp. has successfully completed a human study comparing oral DehydraTECH-liraglutide to injected Saxenda®-branded liraglutide, with partial results now available [1][8] - The study demonstrated a 22.7% reduction in adverse events (AEs) for oral DehydraTECH-liraglutide compared to Saxenda®, with significant reductions in nausea (67%) and gastrointestinal AEs (31%) [3][4] - Lexaria is seeking a pharmaceutical partner to develop an FDA-registered oral alternative to current injectable GLP-1 drugs, addressing an unmet market need [2][10] Study Details - The study involved 10 overweight volunteers, comparing daily doses of Saxenda® (0.6 mg) and DehydraTECH-liraglutide (45 mg) over a 7-day period [13] - The primary endpoint was the evaluation of safety and tolerability, with secondary objectives including pharmacokinetics and effects on body weight, blood glucose, and insulin levels [16] - Weight loss was observed in 9 out of 10 participants in both study arms, although it was not the primary goal of the study [5] Technology and Market Context - DehydraTECH is a patented drug delivery technology that enhances bio-absorption and reduces side effects, with 48 patents granted and more pending [17] - The study's results suggest that DehydraTECH-liraglutide could provide a viable oral alternative to Saxenda® and other injectable liraglutide products, which generated significant revenue for Novo Nordisk [12] - Lexaria's approach may allow for an expedited FDA regulatory pathway under the 505(b)(2) application, contingent on demonstrating comparable performance to existing injectable versions [6][10]
