Solution Overview

Problem

Current asthma treatments, particularly corticosteroids, come with significant side effects and limited long-term benefits, and there is a need for effective and safe therapeutic approaches as well as reliable biomarkers to assess asthma severity and treatment efficacy.

Innovation Solution

Administration of Semaphorin 3A or its derivatives to patients with asthma, which modulates T regulatory cells by increasing Foxp3 expression, thereby reducing inflammation, and using Semaphorin 3A levels in biological samples to assess asthma severity and treatment efficacy.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If inhaled corticosteroids are administered to treat asthma, then asthma symptoms are greatly reduced, but systemic side effects occur including adrenal suppression, decreased bone metabolism, decreased growth in children, and increased susceptibility to infections

Engineering Contradiction:
Improveasthma symptom controlVSAvoidsystemic side effects
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent introduces Semaphorin 3A as a mediator substance that acts locally in the airways to reduce inflammation and symptoms. Instead of using corticosteroids that systemically affect the body, Semaphorin 3A serves as an intermediary agent that targets asthma pathology specifically in the respiratory tract through its anti-inflammatory and immunomodulatory properties, thereby achieving symptom control without the harmful systemic side effects of traditional corticosteroid therapy

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If continuous daily treatment with corticosteroids is administered, then incidence of asthma symptoms is reduced, but long-term therapeutic benefit in terms of lung function is not achieved and progressive lung changes are not prevented

Engineering Contradiction:
Improvesymptom incidence reductionVSAvoidlong-term lung function benefit
Core Design Contradiction:
ReliabilityVSDuration of action of stationary object

Solution Approach 1:

The patent utilizes the parameter of Semaphorin 3A concentration and its biological activity to achieve sustained therapeutic effects. By administering Semaphorin 3A at appropriate doses and frequencies, the treatment modifies the inflammatory and immune parameters in the airways, leading to both short-term symptom reduction and long-term preservation of lung function through mechanisms that differ from corticosteroid pathways

Inventive Principle:
Principle #35Parameter changes

3Adaptability or versatility

If alternative therapeutic approaches including leukotriene inhibitors and anti-IgE are used, then treatment options are expanded, but only marginal benefits are shown

Engineering Contradiction:
Improvetreatment option diversityVSAvoidtreatment efficacy
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent positions Semaphorin 3A as a multi-functional therapeutic agent that can be applied across different asthma phenotypes and severity levels. Unlike alternative therapies that target specific pathways with limited efficacy, Semaphorin 3A exhibits universal anti-inflammatory, immunomodulatory, and tissue-protective effects that provide robust clinical benefits across diverse patient populations, making it a versatile and reliable treatment option

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