Rivus Pharmaceuticals develops Controlled Metabolic Accelerators (CMAs), oral small molecules that utilize mitochondrial uncoupling to enhance fat oxidation and improve cellular metabolism. Their lead candidate, HU6, targets obesity and related cardiometabolic diseases by promoting fat-specific weight loss while preserving muscle mass and improving key metabolic parameters.

Problem
Obesity and related cardiometabolic diseases, such as heart failure with preserved ejection fraction (HFpEF), metabolic dysfunction-associated steatotic liver disease (MASLD), and type 2 diabetes, are driven by excess fat accumulation. Current weight loss therapies may also reduce lean muscle mass, potentially leading to weight regain and increased cardiovascular risk.
Solution
Rivus Pharmaceuticals develops Controlled Metabolic Accelerators (CMAs), oral small molecules designed to reduce excess fat and treat a range of cardiometabolic diseases. CMAs safely leverage mitochondrial uncoupling, a natural metabolic process, to promote fat-specific weight loss while preserving muscle mass. By increasing the breakdown of fats and sugars and increasing resting energy expenditure, CMAs improve cellular metabolism and address the underlying cause of cardiometabolic diseases. Rivus' lead CMA candidate, HU6, is currently in clinical development for obesity and associated cardiometabolic diseases.
Target Audience
The primary target audience includes patients with obesity and related cardiometabolic diseases such as heart failure with preserved ejection fraction (HFpEF), metabolic dysfunction-associated steatotic liver disease (MASLD) / metabolic dysfunction-associated steatohepatitis (MASH) and Type 2 diabetes, as well as physicians and healthcare providers treating these conditions.
