Solution Overview

Problem

Current methods for administering STING agonists face challenges in achieving effective cytokine production in disease tissues without causing adverse systemic immune responses, leading to inefficient treatment outcomes for diseases like cancer and autoimmune disorders.

Innovation Solution

Systemic administration of a STING agonist that selectively increases cytokine concentrations in tumor microenvironments or disease tissues, maintaining a favorable therapeutic index by avoiding excessive cytokine production in the bloodstream, thereby minimizing adverse effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If STING agonists are administered systemically to stimulate immune response, then cytokine production in disease tissues is enhanced, but excessive cytokine production in bloodstream causes adverse systemic immune responses

Engineering Contradiction:
Improvetreatment effectivenessVSAvoidadverse systemic immune responses
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs targeted delivery systems including antibodies conjugated to STING agonists, ligand-receptor targeting pairs, and nanoparticle carriers that direct the agonists specifically to tumor microenvironments and diseased tissues. This ensures high cytokine production locally at the disease site while maintaining low systemic cytokine levels, thereby achieving effective treatment without adverse systemic immune responses

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent uses targeting molecules such as antibodies, ligands, and nanoparticle carriers as intermediaries to deliver STING agonists to disease tissues. These intermediaries enable selective accumulation of the agonist at the target site through specific binding interactions, allowing differential cytokine production between diseased and healthy tissues

Inventive Principle:
Principle #24Intermediary (Mediator)

2Productivity

If high doses of STING agonists are used to achieve effective cytokine production, then treatment efficacy increases, but systemic toxicity increases

Engineering Contradiction:
Improvecytokine production efficiencyVSAvoidsystemic toxicity
Core Design Contradiction:
ProductivityVSObject-affected harmful factors

Solution Approach 1:

The patent achieves high local cytokine production at disease sites through targeted delivery, allowing effective immune stimulation without requiring high systemic doses. The targeting systems concentrate the agonist at the tumor microenvironment, creating a high local concentration that drives cytokine production while maintaining low systemic exposure and minimizing toxicity

Inventive Principle:
Principle #3Local quality

Solution Approach 2:

The patent employs antibody-agonist conjugates where the antibody component acts as a targeting vehicle that copies the specificity of natural immune recognition. This allows the STING agonist to be delivered precisely to antigen-positive tumor cells, achieving high local efficacy at low overall doses

Inventive Principle:
Principle #26Copying
