Solution Overview

Problem

Existing treatments for LAG-3 positive tumors are inadequate in effectively inhibiting tumor growth and inducing anti-tumor activity.

Innovation Solution

Administering a combination of a LAG-3 antagonist, a PD-1 pathway inhibitor, and one or more chemotherapeutic agents to patients with LAG-3 positive tumors to enhance immune response and inhibit tumor growth.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If a LAG-3 antagonist is administered alone, then immune activation is enhanced, but anti-tumor activity is insufficient

Engineering Contradiction:
Improveimmune activationVSAvoidanti-tumor activity
Core Design Contradiction:
ReliabilityVSProductivity

Solution Approach 1:

The patent combines a LAG-3 antagonist with a PD-1 pathway inhibitor and chemotherapeutic agents into a multi-component therapy regimen. This merging of different therapeutic mechanisms synergistically enhances both immune activation and anti-tumor activity, resolving the contradiction where single-agent LAG-3 inhibition provides immune activation but insufficient anti-tumor effect.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The therapy functions as a composite treatment system integrating multiple agents with different modes of action: LAG-3 antagonist for immune activation, PD-1 pathway inhibitor for immune checkpoint blockade, and chemotherapeutic agents for direct tumor cell killing. This composite approach achieves superior anti-tumor activity compared to any single component.

Inventive Principle:
Principle #40Composite materials

2Productivity

If a PD-1 pathway inhibitor is administered alone, then immune resistance is overcome, but treatment efficacy is limited

Engineering Contradiction:
Improveanti-tumor activityVSAvoidtreatment efficacy
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The combination therapy merges PD-1 pathway inhibition with LAG-3 antagonism and chemotherapeutic agents. This synergistic combination overcomes immune resistance more effectively than PD-1 inhibition alone while improving overall treatment efficacy through multiple concurrent mechanisms of action.

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The therapy segments the immune response modulation into multiple components: LAG-3 blockade for T cell activation, PD-1 inhibition for checkpoint removal, and chemotherapy for tumor cell destruction. This segmentation allows each component to address specific aspects of tumor immunity, collectively enhancing treatment efficacy.

Inventive Principle:
Principle #1Segmentation

3Productivity

If chemotherapeutic agents are used alone, then tumor growth is inhibited, but immune activation is insufficient

Engineering Contradiction:
Improvetumor growth inhibitionVSAvoidimmune activation
Core Design Contradiction:
ProductivityVSReliability

Solution Approach 1:

The patent merges chemotherapeutic agents with immunotherapy components (LAG-3 antagonist and PD-1 pathway inhibitor). This combination maintains tumor growth inhibition through chemotherapy while simultaneously activating the immune system through immunotherapy, resolving the contradiction where chemotherapy alone provides tumor killing but insufficient immune activation.

Inventive Principle:
Principle #5Merging (Combining)

4Reliability

If combination therapy is administered, then treatment outcomes are improved, but treatment complexity increases

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

Solution Approach 1:

While combining multiple agents does increase treatment complexity, the patent manages this through a structured regimen where the LAG-3 antagonist, PD-1 pathway inhibitor, and chemotherapeutic agents are administered in a coordinated manner. The combination achieves superior treatment outcomes by targeting multiple pathways simultaneously, with the complexity managed through established protocols and monitoring frameworks.

Inventive Principle:
Principle #5Merging (Combining)
