Solution Overview

Problem

Current treatments for amyotrophic lateral sclerosis (ALS) do not effectively address the aggregation of TDP-43 protein, which is associated with the onset and progression of the disease.

Innovation Solution

An agent comprising cycloserine or its salts, such as D-cycloserine, is used to inhibit TDP-43 aggregation, formulated into various dosage forms to treat or prevent ALS.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current treatments for ALS are used, then general symptom management is achieved, but TDP-43 aggregation is not effectively inhibited

Engineering Contradiction:
Improveeffectiveness of TDP-43 aggregation inhibitionVSAvoidapplicability to TDP-43 proteinopathy
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent changes the chemical parameter by selecting cycloserine and its salts as the active component, which has specific biochemical properties that inhibit TDP-43 aggregation. This parameter change (molecular structure and chemical composition) enables effective inhibition of TDP-43 aggregation while being applicable to TDP-43 proteinopathy, resolving the contradiction between treatment effectiveness and disease applicability

Inventive Principle:
Principle #35Parameter changes

2Reliability

If TDP-43 aggregation is inhibited, then cell death is reduced and disease progression is prevented, but the mechanism requires specific chemical properties not provided by current treatments

Engineering Contradiction:
Improvecell death reductionVSAvoidchemical formulation requirements
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent specifies cycloserine and its salts with particular chemical parameters (molecular structure, solubility, stability) that enable TDP-43 aggregation inhibition. By carefully selecting and optimizing these chemical parameters, the patent achieves reliable cell death reduction while managing the complexity of the chemical formulation through focused development on specific compounds with known properties

Inventive Principle:
Principle #35Parameter changes
