Scope of the Patent
General Focus
Patent 9,072,710 primarily covers methods of treating hyperglycemia associated with NASH using specific pharmaceutical protocols. It emphasizes the use of certain drug combinations and dosing strategies that target metabolic pathways implicated in NASH, insulin resistance, and related glucose dysregulation.
Technical Field
The patent's scope extends to pharmaceutical compositions involving agents such as glucagon-like peptide-1 (GLP-1) receptor agonists, sodium-glucose co-transporter 2 (SGLT2) inhibitors, or other hypoglycemic agents administered in particular dosing regimens to treat NASH with concurrent hyperglycemia.
Claims Overview
The claims define the legal scope precisely, demarcating the boundaries of protected methods or compositions. They typically cover:
- Method claims: Specific steps for administering pharmaceutical compositions to treat NASH-associated hyperglycemia.
- Composition claims: Pharmaceutical formulations containing particular agents at specified dosages or ratios.
- Combination claims: Use of multiple agents in combination to achieve therapeutic effects.
The claims are intentionally broad to encompass various drug combinations and dosing schemes, yet specific enough to distinguish over prior art.
Claim Hierarchy
- Independent Claims: Usually broad, covering the core methods of therapeutic intervention using specific agents and dosing strategies.
- Dependent Claims: Narrower, detailing particular formulations, administration schedules, or patient populations, thus adding layers of specificity.
Claim Analysis
1. Therapeutic Method Claims
The core claims relate to administering a combination of agents—for example, a GLP-1 receptor agonist and an SGLT2 inhibitor—to patients diagnosed with NASH displaying hyperglycemia. These claims specify:
- The route of administration (e.g., injectable, oral).
- The dosage ranges for each agent.
- The duration of treatment and administration intervals.
2. Composition and Formulation Claims
Claims might encompass pharmaceutical compositions comprising active ingredients in predetermined ratios, with specific excipients or delivery systems optimized for treating NASH with hyperglycemia.
3. Use Claims
Claims may also extend to the therapeutic use of these combinations for reducing liver fat content, improving insulin sensitivity, or decreasing inflammatory markers associated with NASH, establishing a patent for the specific therapeutic indications.
4. Dosing Regimen Claims
A notable aspect is the emphasis on particular dosing regimens—such as titration protocols or fixed-dose combinations—that optimize efficacy and minimize side effects, adding a layer of innovation related to treatment protocols.
Claim Novelty and Inventive Step
The patent claims are distinguished from prior art by integrating multiple agents in tailored regimens specific to NASH pathology with a focus on hyperglycemia management. The inventive step hinges on synergistic combination therapy tailored to metabolic indications, representing an advancement over monotherapy approaches.
