Solution Overview

Problem

Current treatments for respiratory disorders associated with excessive mucus production, such as asthma, COPD, IPF, and CF, are inadequate in effectively modulating the Notch signaling pathway to reduce mucus production and improve lung function.

Innovation Solution

The use of modified oligonucleotides complementary to Notch signaling pathway transcripts, specifically targeting Notch1, Notch2, Notch3, Notch4, JAG1, JAG2, DLL1, DLL3, DLL4, or Hes-1, to inhibit the expression or activity of these pathways, thereby reducing mucus production and enhancing trans-differentiation from club cells to ciliated cells, leading to improved lung function.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional treatments are used for respiratory disorders, then general symptom management is achieved, but effective modulation of the Notch signaling pathway to reduce mucus production is not achieved

Engineering Contradiction:
Improveeffectiveness of treatmentVSAvoidmucus production
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent extracts and targets the specific Notch signaling pathway as the source of excessive mucus production. By using modified oligonucleotides that specifically bind to Notch pathway transcripts (Notch1, Notch2, Notch3, Notch4, JAG1, JAG2, DLL1, DLL3, DLL4, or Hes-1), the invention isolates and inhibits this particular signaling pathway while leaving other physiological functions intact, thereby reducing mucus production without broad suppressive effects

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent changes the molecular parameters of the treatment by using chemically modified oligonucleotides with enhanced stability and specificity. These modified oligonucleotides alter the pharmacokinetic and pharmacodynamic parameters of Notch pathway inhibition, achieving more reliable and sustained reduction of mucus production compared to conventional treatments

Inventive Principle:
Principle #35Parameter changes

2Reliability

If modified oligonucleotides are used to inhibit Notch signaling pathway, then mucus production is reduced and lung function is improved, but treatment complexity increases

Engineering Contradiction:
Improvelung function improvementVSAvoidtreatment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent introduces modified oligonucleotides as intermediary molecules that mediate between the administered treatment and the Notch signaling pathway. These oligonucleotides serve as specific mediators that bind to target transcripts and inhibit translation, providing a controlled and specific mechanism to improve lung function while managing treatment complexity through targeted action

Inventive Principle:
Principle #24Intermediary (Mediator)

3Object-generated harmful factors

If Notch signaling pathway is inhibited to decrease mucus production, then respiratory disorder symptoms are ameliorated, but trans-differentiation from club cells to ciliated cells must be enhanced

Engineering Contradiction:
Improvemucus productionVSAvoidcell trans-differentiation
Core Design Contradiction:
Object-generated harmful factorsVSAdaptability or versatility

Solution Approach 1:

The patent applies local quality control by selectively inhibiting Notch signaling in specific cell types (club cells and goblet cells) where it drives excessive mucus production, while allowing or promoting trans-differentiation in other contexts. The modified oligonucleotides target specific transcripts locally, creating different outcomes in different cell populations - reducing mucus in goblet cells while promoting ciliated cell differentiation from club cells

Inventive Principle:
Principle #3Local quality
