Solution Overview

Problem

Current treatments for neurological disorders such as Parkinson's disease, Huntington's disease, and others are limited by low brain-derived neurotrophic factor (BDNF) levels, which are not effectively addressed by existing therapies.

Innovation Solution

Laquinimod, a novel synthetic compound with high oral bioavailability, is administered periodically to increase BDNF serum levels in humans, either alone or in combination with other BDNF-increasing agents, for treating various BDNF-related diseases.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If existing therapies are used for neurological disorders, then treatment is provided, but BDNF levels remain low and are not effectively addressed

Engineering Contradiction:
Improveeffectiveness of treatmentVSAvoidBDNF levels
Core Design Contradiction:
ReliabilityVSQuantity of substance

Solution Approach 1:

The patent changes the chemical parameter by introducing laquinimod, a novel synthetic compound with a specific chemical structure (N-ethyl-N-phenyl-1,2-dihydro-4-hydroxy-5-chloro-1-methyl-2-oxoquinoline-3-carboxamide). This compound specifically targets and increases BDNF levels, resolving the contradiction by changing the chemical composition parameter of the treatment to achieve both therapeutic effectiveness and elevated BDNF levels

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

Laquinimod acts as an intermediary substance that mediates between the administration route and the target BDNF levels. The compound serves as a carrier mechanism to achieve the desired biological effect, bridging the gap between existing therapy limitations and the need for increased BDNF

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If laquinimod is administered to increase BDNF levels, then therapeutic benefits are achieved, but the complexity of treatment regimen increases

Engineering Contradiction:
Improvetherapeutic benefitVSAvoidtreatment regimen complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Laquinimod is designed with multi-functionality, serving both as an immunomodulator (for multiple sclerosis treatment) and as a BDNF-elevating agent (for neurological disorders). This universal compound addresses multiple therapeutic needs simultaneously, reducing overall treatment complexity while maintaining therapeutic benefits

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

Solution Approach 2:

The patent specifies periodic administration of laquinimod (e.g., once daily or once weekly) rather than continuous dosing. This periodic action maintains therapeutic BDNF levels while simplifying the treatment regimen and improving patient compliance, thereby resolving the contradiction between therapeutic effectiveness and regimen complexity

Inventive Principle:
Principle #19Periodic action
