Solution Overview

Problem

Current immunotherapies for cancer lack predictive biomarkers to identify which patients will respond effectively, leading to variable treatment outcomes and inefficiencies in personalized medicine.

Innovation Solution

The use of elevated expression levels of specific genes (ABCA1, TMEM245, ATP13A3, and OLR1) as molecular signatures to predict patient response to immunotherapies, particularly immune checkpoint immunotherapies, allowing for the identification of subjects likely to benefit from these treatments.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If immunotherapies are administered to cancer patients, then treatment coverage is improved, but treatment effectiveness varies significantly because predictive biomarkers are lacking

Engineering Contradiction:
Improvetreatment coverageVSAvoidtreatment effectiveness
Core Design Contradiction:
Adaptability or versatilityVSReliability

Solution Approach 1:

The patent applies preliminary action by determining gene expression levels (ABCA1, TMEM245, ATP13A3, OLR1) before administering immunotherapy to identify patients likely to respond. This pre-screening approach allows clinicians to predict treatment outcomes in advance, ensuring that immunotherapy is directed toward patients with elevated expression of these genes, thereby improving both treatment coverage and effectiveness.

Inventive Principle:
Principle #10Preliminary action

2Ease of operation

If molecular signatures are used to predict immunotherapy response, then personalized treatment is improved, but measurement complexity increases

Engineering Contradiction:
Improvepersonalized treatmentVSAvoidmeasurement complexity
Core Design Contradiction:
Ease of operationVSDifficulty of detecting and measuring

Solution Approach 1:

The patent applies segmentation by dividing the complex task of predicting immunotherapy response into measurement of specific, discrete gene expression levels (ABCA1, TMEM245, ATP13A3, OLR1). Rather than analyzing the entire genome, the invention focuses on this specific subset of genes, making the measurement process more manageable and clinically feasible while still providing accurate personalized treatment predictions.

Inventive Principle:
Principle #1Segmentation
