United States Patent 9,474,780: A Detailed Analysis of Scope, Claims, and Patent Landscape
Introduction
United States Patent 9,474,780, granted to Eli Lilly and Company, is a significant patent in the biopharmaceutical industry, particularly in the context of diabetes treatment and incretin hormone therapy. This patent focuses on GIP/GLP-1 co-agonist compounds, specifically tirzepatide, and its pharmaceutical compositions.
Background
Incretin hormones, such as Glucose-dependent Insulinotropic Polypeptide (GIP) and Glucagon-like Peptide-1 (GLP-1), play crucial roles in glucose metabolism and insulin secretion. Dual agonists that target both GIP and GLP-1 receptors have shown promising results in managing type 2 diabetes by enhancing insulin secretion, suppressing glucagon release, and promoting weight loss.
Patent Overview
Title and Abstract
The patent titled "GIP and GLP-1 co-agonist compounds" describes and claims compositions containing tirzepatide, a dual incretin peptide mimetic compound. The abstract highlights the use of these compounds in simultaneous, separate, or sequential combination with other agents for treating metabolic disorders, including type 2 diabetes[4].
Claims and Scope
Independent Claims
The patent includes several independent claims that define the scope of the invention. These claims cover:
- The composition of tirzepatide itself.
- Pharmaceutical compositions containing tirzepatide in combination with various excipients.
- Methods of treating metabolic disorders using these compositions.
- Specific formulations for parenteral administration, such as injectable solutions[4].
Dependent Claims
Dependent claims further specify the details of the independent claims, including:
- Concentrations of tirzepatide and other components like NaCl and propylene glycol.
- pH ranges and stability conditions for the pharmaceutical compositions.
- Methods of preparation and administration routes[5].
