The patent is assigned to Novo Nordisk A/S and covers a novel pharmaceutical composition and its use in treating metabolic disorders, including type 2 diabetes, obesity, and non-alcoholic fatty liver disease (NAFLD). The core innovation lies in a specific peptide analog that enhances glucose regulation and promotes weight loss through a dual mechanism of action.
What is the Core Invention of Patent 12,128,132?
The primary claims of Patent 12,128,132 define a specific chemical structure and its pharmaceutical formulation. This structure is a peptide analog that functions as a glucagon-like peptide-1 (GLP-1) receptor agonist and a glucose-dependent insulinotropic polypeptide (GIP) receptor agonist. This dual agonism is a key differentiator, aiming to provide superior efficacy in glycemic control and weight management compared to single-agonist therapies.
The patent describes the peptide analog with a defined amino acid sequence and specific modifications to enhance its pharmacokinetic profile, such as increased half-life and improved oral bioavailability, although the primary delivery method described is subcutaneous injection.
The claims further encompass:
- Specific Chemical Structures: The patent claims a range of specific peptide sequences that fall within the scope of the invention, providing a broad protection. For example, claims often delineate a core structure with allowable variations at specific amino acid positions.
- Pharmaceutical Compositions: Claims include formulations containing the active peptide analog along with pharmaceutically acceptable excipients. These excipients are detailed to ensure stability, solubility, and effective delivery.
- Methods of Treatment: The patent asserts claims for the use of the composition in treating specific metabolic disorders, including type 2 diabetes, obesity, and NAFLD. These claims specify patient populations and treatment regimens.
