Solution Overview

Problem

Current methods for predicting the effectiveness of immunotherapy in cancer patients lack reliable biological markers, making it difficult to determine the prognosis and outcome of treatment, particularly for renal cell carcinoma (RCC) and colorectal carcinoma (CRC).

Innovation Solution

A method using a panel of biomarkers such as ApoA1, CCL17/TARC, CXCL13/BCA-1, neutrophils, eosinophils, monocytes, CD95/Fas, ASAT/SGOT, and others to predict the beneficial effect of immunotherapy, including peptide-based vaccines, and monitor treatment response in cancer patients.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current prediction methods are used, then treatment can proceed, but reliability of prediction is insufficient

Engineering Contradiction:
Improveprediction reliabilityVSAvoidlack of biological markers
Core Design Contradiction:
ReliabilityVSLoss of information

Solution Approach 1:

The patent segments the prediction system into multiple independent biomarker components (ApoA1, CCL17/TARC, CXCL13/BCA-1, and cellular parameters) that can be measured separately and combined to form a comprehensive prediction model, thereby improving reliability through multi-factor analysis

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent develops a universal prediction method that can be applied across different cancer types (renal cell carcinoma, colorectal carcinoma, and other solid tumors) using the same panel of biomarkers, making the solution broadly applicable and reliable for diverse clinical scenarios

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

2Measurement precision

If a panel of biomarkers is used, then prediction accuracy improves, but device complexity increases

Engineering Contradiction:
Improveprediction accuracyVSAvoidbiomarker panel complexity
Core Design Contradiction:
Measurement precisionVSDevice complexity

Solution Approach 1:

The complex prediction task is segmented into measurements of distinct, well-defined biomarkers (ApoA1, CCL17/TARC, CXCL13/BCA-1, neutrophils, eosinophils, monocytes, CD95/Fas, ASAT/SGOT) that can be processed independently and then integrated, making the complexity manageable through modular measurement approaches

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The patent introduces a standardized biomarker panel as an intermediary layer between the patient sample and the clinical decision-making process, translating complex biological information into interpretable prediction results through defined measurement protocols and reference ranges

Inventive Principle:
Principle #24Intermediary (Mediator)

3Productivity

If immunotherapy is administered without reliable prediction, then treatment access is improved, but loss of time due to ineffective treatment increases

Engineering Contradiction:
Improvetreatment accessVSAvoidtime lost to ineffective treatment
Core Design Contradiction:
ProductivityVSLoss of time

Solution Approach 1:

The patent performs preliminary prediction using the biomarker panel before initiating immunotherapy, identifying patients likely to respond favorably in advance, thereby preventing time loss from ineffective treatments while maintaining access for those who will benefit

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent establishes a feedback mechanism where biomarker measurements inform treatment decisions, creating a closed-loop system that directs immunotherapy to responsive patients and alternative treatments to non-responders, optimizing time utilization across the patient population

Inventive Principle:
Principle #23Feedback
