Solution Overview

Problem

Current methods for diagnosing and treating immune-mediated inflammatory diseases, such as Takayasu arteritis and giant cell arteritis, rely on IL-6 inhibitors, which can lead to long-term complications like large blood vessel stenosis and dilation, and there is a need for alternative biomarkers and treatments.

Innovation Solution

The use of MMP12 as a biomarker for diagnosing immune-mediated inflammatory diseases, through measuring MMP12 protein levels in biological samples, and developing diagnostic drugs and therapeutic agents that interact specifically with MMP12 to detect, predict, and treat these diseases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If IL-6 inhibitors are used for treating immune-mediated inflammatory diseases, then treatment effectiveness is improved, but long-term complications such as large blood vessel stenosis and dilation progress

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidblood vessel stenosis and dilation
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent changes the therapeutic target from IL-6 to MMP12, representing a fundamental parameter change in the treatment approach. By targeting MMP12 instead of IL-6, the invention maintains treatment effectiveness while avoiding the harmful vascular complications associated with IL-6 inhibition

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent extracts MMP12 as a specific therapeutic target from the broader inflammatory pathway. By identifying and targeting MMP12 specifically, the invention isolates a more precise therapeutic intervention point that avoids the off-target effects of IL-6 inhibition

Inventive Principle:
Principle #2Taking out (Extraction)

2Measurement precision

If MMP12 is used as a biomarker for diagnosing immune-mediated inflammatory diseases, then diagnostic accuracy is improved, but reliance on IL-6 as an indicator is reduced

Engineering Contradiction:
Improvediagnostic accuracyVSAvoidIL-6 indicator dependency
Core Design Contradiction:
Measurement precisionVSLoss of information

Solution Approach 1:

The patent replaces the established but problematic IL-6 indicator with MMP12 as a new diagnostic biomarker. This substitution provides a fresh measurement approach that maintains diagnostic capability while eliminating dependency on the flawed IL-6 pathway

Inventive Principle:
Principle #27Cheap short-living objects (Disposable)

Solution Approach 2:

The patent changes the diagnostic parameter from IL-6 levels to MMP12 levels. This parameter change enables accurate disease detection and monitoring while providing information independent of the IL-6 pathway, thereby reducing diagnostic dependency on that pathway

Inventive Principle:
Principle #35Parameter changes
