Solution Overview

Problem

Not all patients respond to proteasome inhibitors for cancer treatment, and the underlying mechanism for this variability is not well understood, particularly regarding the NF-κB2 gene and its role in responsiveness to these inhibitors.

Innovation Solution

Detecting the presence, truncation, or translocation of the NF-κB2 gene in cancer patients to determine their responsiveness to proteasome inhibitors, and administering effective amounts of proteasome inhibitors or alternative agents like immunomodulators or DNA damaging agents based on these genetic markers.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Productivity

If proteasome inhibitors are administered to all cancer patients, then treatment coverage is maximized, but treatment effectiveness decreases due to lack of responsiveness in some patients

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidpatient responsiveness
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent performs preliminary genetic testing to detect the NF-κB2 gene 3' end sequence before administering proteasome inhibitors. This preliminary action identifies patients who are likely to respond to treatment, allowing for selective administration to only those patients, thereby improving treatment effectiveness and reducing waste in non-responders.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent uses the presence or absence of the NF-κB2 gene 3' end sequence as a biomarker parameter to stratify patients into different treatment groups. By changing the approach from uniform treatment to stratified treatment based on this genetic parameter, the patent improves treatment responsiveness and effectiveness.

Inventive Principle:
Principle #35Parameter changes

2Reliability

If genetic testing for NF-κB2 is performed to identify responsive patients, then treatment responsiveness is improved, but testing complexity and cost increase

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

Solution Approach 1:

The patent extracts and focuses on a specific, critical region of the NF-κB2 gene (the 3' end sequence) for testing, rather than performing comprehensive genomic analysis. This extraction approach simplifies the testing process while maintaining sufficient accuracy to predict treatment responsiveness, thereby reducing testing complexity and cost.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The patent uses the NF-κB2 gene 3' end sequence as an intermediary biomarker that indirectly predicts treatment responsiveness. This intermediary approach provides a simple, direct test result that can be used for treatment decision-making without requiring complex multi-parameter analysis or multiple tests.

Inventive Principle:
Principle #24Intermediary (Mediator)

3Ease of operation

If proteasome inhibitors are administered without genetic screening, then treatment administration is simplified, but resource waste increases due to ineffective treatment in non-responders

Engineering Contradiction:
Improvetreatment administrationVSAvoidresource waste
Core Design Contradiction:
Ease of operationVSLoss of substance

Solution Approach 1:

The patent performs a simple preliminary genetic test before treatment administration to identify suitable candidates. This preliminary action filters out non-responders before treatment begins, preventing resource waste on ineffective treatments while maintaining ease of operation through a straightforward testing and treatment protocol.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent changes the approach from blind treatment administration to parameter-guided administration based on the NF-κB2 gene 3' end sequence status. This parameter-based stratification ensures resources are allocated to patients who will benefit, reducing waste while keeping the process simple and operationally easy.

Inventive Principle:
Principle #35Parameter changes
