Addressing Significant Unmet Needs in Obesity
Obesity is an unprecedented epidemic that is driving cardiometabolic diseases – the leading cause of death and disability worldwide. Obesity leads to metabolic dysfunction and a cascade of cardiometabolic diseases, including liver disease (MASH) and heart failure (HFpEF).
Obesity – A Chronic Disease
- Significant Epidemiology: Obesity is estimated to affect 1 billion individuals worldwide.1 The prevalence of obesity worldwide has more than doubled since 1990 and is a global health crisis.2
- Serious Medical Consequences: Obesity is a chronic disease that if left untreated is a primary driver of a spectrum of chronic diseases, including MASH, type 2 diabetes, coronary heart disease, and different types of cancer, significantly reducing both quality of life, and overall life expectancy.
- Limitations with GLP-1s: Currently approved GLP-1 receptor agonists have delivered benefits to individuals living with obesity and associated cardiometabolic diseases, however approximately 75% of patients stop treatment within 2 years.3 Further, around 40% of the total weight loss is lean muscle,4 which is critical for long-term function and cardiometabolic health, in particular for older patients at risk of sarcopenia. After stopping treatment, patients regain weight rapidly,5 mostly in the form of fat, potentially leaving them worse off metabolically.6
Obesity Needs New Treatment Options
Obesity is a chronic disease that needs therapies for chronic use. We are advancing RV-8451, a highly-differentiated oral GLP-1, in IND-enabling studies in obesity.
RV-8451 is the industry’s first oral muscle-preserving GLP-1 non-peptide agonist. RV-8451 decreases energy intake as a GLP-1 and increases energy expenditure by preserving muscle. This differentiated GLP-1 is designed to deliver high-quality, fat-specific, durable weight loss with convenient oral dosing.
