Solution Overview

Problem

Current treatments for amyotrophic lateral sclerosis (ALS) are limited, with no clear diagnostic test and few effective pharmacologic therapies available, leading to a need for novel and effective therapies to address the progressive degeneration of motor neurons and associated symptoms.

Innovation Solution

The development of novel combinatorial therapies using drug combinations such as baclofen and acamprosate, torasemide and baclofen, cinacalcet and mexiletine, or sulfisoxazole and torasemide, which are administered alone or in combination with riluzole, to provide protective effects against glutamate toxicity and delay motor neuron degeneration.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional single-drug therapies are used for ALS, then treatment simplicity is maintained, but therapeutic efficacy is insufficient to slow disease progression

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoidtreatment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines multiple drugs with different mechanisms of action into a single therapeutic regimen. Specifically, it integrates riluzole (which modulates glutamate activity) with edaravone (a free radical scavenger) and/or vitamin E (an antioxidant), creating a multi-target therapy that addresses different pathogenic mechanisms of ALS simultaneously, thereby improving therapeutic efficacy while presenting a unified treatment approach

Inventive Principle:
Principle #5Merging (Combining)

2Measurement precision

If no diagnostic test is available, then diagnostic simplicity is maintained, but diagnostic precision is insufficient to confirm ALS

Engineering Contradiction:
Improvediagnostic precisionVSAvoiddiagnostic complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The diagnostic approach is segmented into multiple independent assessment components: clinical evaluation of motor neuron symptoms, neurological examination findings, electrodiagnostic testing (EMG/NCS), and exclusion of alternative diagnoses. This segmentation allows for systematic evaluation of different aspects of the disease presentation, improving diagnostic precision through a structured multi-step process rather than relying on a single complex test

Inventive Principle:
Principle #1Segmentation

3Reliability

If current limited therapies are used, then treatment availability is maintained, but disease progression control is insufficient

Engineering Contradiction:
Improvedisease progression controlVSAvoidtreatment options
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent creates a universal therapeutic framework that can be adapted to different ALS patients based on their specific disease characteristics. The core regimen of riluzole combined with edaravone and/or vitamin E serves as a versatile base that addresses multiple pathogenic mechanisms (glutamate excitotoxicity, oxidative stress, free radical damage) simultaneously, allowing the treatment to be effective across different ALS subtypes and progression rates while maintaining a consistent core approach

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