Solution Overview

Problem

There are limited treatment options for Alport syndrome, a rare hereditary disease causing glomerular filtration rate decline and leading to end-stage renal disease, with existing treatments like bardoxolone methyl showing adverse effects in certain patient populations.

Innovation Solution

Administer bardoxolone methyl or its analogues in specific patient populations, excluding those with endothelial dysfunction risk factors, to treat or prevent Alport syndrome by improving kidney function and reducing inflammation and fibrosis.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If bardoxolone methyl is administered to treat Alport syndrome, then kidney function is improved and inflammation is reduced, but the complexity of treatment formulation and administration increases

Engineering Contradiction:
Improvekidney functionVSAvoidtreatment formulation
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent utilizes different polymorphic forms (Form A crystalline, Form B amorphous/glassy) of bardoxolone methyl with distinct physical parameters (X-ray diffraction patterns, glass transition temperatures) to optimize drug delivery and efficacy while managing formulation complexity

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent employs composite formulation approaches by combining bardoxolone methyl with various excipients and delivery systems (liposomes, emulsions, solid dispersions) to enhance therapeutic effect while systematically managing the complexity of treatment administration

Inventive Principle:
Principle #40Composite materials

2Duration of action of stationary object

If bardoxolone methyl treatment is implemented, then progression of kidney damage is slowed, but the availability of effective treatment options remains limited

Engineering Contradiction:
Improvedisease progressionVSAvoidtreatment options
Core Design Contradiction:
Duration of action of stationary objectVSAdaptability or versatility

Solution Approach 1:

The patent positions bardoxolone methyl as a multi-functional therapeutic agent that addresses multiple aspects of Alport syndrome pathophysiology simultaneously: reducing oxidative stress, inhibiting pro-inflammatory signaling pathways, and preventing fibrosis, thereby providing a versatile treatment option for this condition

Inventive Principle:
Principle #6Universality (Multi-functionality)

3Object-affected harmful factors

If bardoxolone methyl is used to inhibit pro-fibrotic signaling pathways, then fibrosis is reduced, but the mechanism of action becomes more complex

Engineering Contradiction:
ImprovefibrosisVSAvoidmechanism of action
Core Design Contradiction:
Object-affected harmful factorsVSDevice complexity

Solution Approach 1:

The patent focuses on extracting and targeting specific pro-fibrotic signaling pathways (TGF-β, CTGF, endothelin-1) among the multiple pathways affected by bardoxolone methyl, thereby simplifying the understanding and monitoring of the drug's anti-fibrotic mechanism while maintaining comprehensive therapeutic effect

Inventive Principle:
Principle #2Taking out (Extraction)
