Solution Overview

Problem

Current diagnostic and treatment methods for breast, prostate, colorectal, lung, and other cancers are limited in effectively targeting cancer stem cells, leading to inadequate prognosis and treatment outcomes due to phenotypic diversity and heterogeneity in tumors.

Innovation Solution

Development of antibodies that specifically bind to the non-ligand binding region of the extracellular domain of human NOTCH receptors, inhibiting tumor cell growth and targeting cancer stem cells in these cancers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current diagnostic and treatment methods are used, then treatment can be provided to cancer patients, but the methods are limited in effectively targeting cancer stem cells leading to inadequate prognosis and treatment outcomes

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidability to target cancer stem cells
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The invention segments the therapeutic approach by developing separate antibodies targeting different NOTCH receptors (NOTCH1, NOTCH2, NOTCH3, NOTCH4) and their ligands, allowing selective inhibition of specific NOTCH signaling pathways in cancer stem cells while preserving other cellular functions

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention uses antibodies as intermediary molecules that bind to NOTCH receptors or ligands, blocking the interaction between ligands and receptors, thereby preventing NOTCH signaling activation in cancer stem cells without directly contacting or damaging the cells

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If antibodies binding to non-ligand binding region of NOTCH receptors are used, then tumor cell growth is inhibited and cancer stem cells are targeted, but the complexity of the treatment increases

Engineering Contradiction:
Improvetreatment outcomeVSAvoidtreatment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The invention creates a universal therapeutic platform using antibodies that can target multiple NOTCH receptors (NOTCH1-4) and their ligands (DLL1-4, JAG1-2), providing multi-functional cancer treatment capability through a single approach that can be applied across different cancer types

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