Solution Overview

Problem

Current therapeutic methods are inadequate for effectively treating liver conditions such as chronic liver disease and liver cancer, as they fail to address the underlying mechanisms of Notch signaling in adult hepatocyte formation and liver damage.

Innovation Solution

Administration of Notch2-specific antagonists, specifically anti-Notch2 NRR antibodies that bind to the LNR-A and HD-C domains, to inhibit Notch2 signaling, promoting hepatocyte differentiation and reducing biliary damage in liver conditions.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current therapeutic methods are used for liver conditions, then treatment is provided, but they fail to effectively address Notch signaling mechanisms and underlying disease causes

Engineering Contradiction:
Improveeffectiveness of treatmentVSAvoidability to address Notch signaling mechanisms
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent introduces Notch2-specific antagonist antibodies as intermediary molecules that specifically bind to and inhibit Notch2 signaling pathways. These antibodies act as mediators between the therapeutic intervention and the disease mechanism, selectively blocking the aberrant Notch2 signaling that drives liver cancer and fibrosis while leaving other pathways intact.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent changes the therapeutic parameter from general liver treatment to specific Notch2 pathway inhibition. By targeting the molecular parameter of Notch2 signaling activity rather than general liver function, the treatment achieves higher effectiveness against diseases driven by this specific pathway while maintaining selectivity.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If Notch2-specific antagonists are administered to inhibit Notch2 signaling, then hepatocyte differentiation is promoted and biliary damage is reduced, but the complexity of targeted therapy increases

Engineering Contradiction:
Improvehepatocyte function and liver histologyVSAvoidcomplexity of targeted therapy
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts and isolates the specific Notch2 signaling pathway from the complex network of liver cell signaling. By focusing therapy exclusively on blocking Notch2 rather than addressing multiple pathways simultaneously, the treatment simplifies the therapeutic approach while maintaining high effectiveness for diseases driven by this specific pathway.

Inventive Principle:
Principle #2Taking out (Extraction)

3Object-affected harmful factors

If conventional treatments are used, then general liver condition management is provided, but they do not specifically reduce biliary damage or improve hepatocyte differentiation

Engineering Contradiction:
Improvebiliary damageVSAvoidsimplicity of treatment approach
Core Design Contradiction:
Object-affected harmful factorsVSEase of manufacture

Solution Approach 1:

The Notch2 antagonist antibodies serve as specific intermediary agents that directly intervene in the pathological process causing biliary damage. By blocking the aberrant Notch2 signaling that drives biliary epithelial cell proliferation and damage, these antibodies provide targeted protection to biliary structures while maintaining a relatively simple administration approach.

Inventive Principle:
Principle #24Intermediary (Mediator)
