Solution Overview

Problem

Current treatments for modulating T cell populations, such as regulatory T cells and cytotoxic T cells, are inadequate for effectively addressing diseases like cancer, as they do not provide sufficient immune modulation or targeting of infected and cancerous cells.

Innovation Solution

Development of interleukin 10 (IL-10) conjugates with modified amino acid sequences and conjugating moieties, including unnatural amino acids, to enhance plasma half-life and maintain functional activity, allowing for targeted immune modulation and treatment of proliferative diseases like cancer.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current treatments for modulating T cell populations are used, then immune system modulation is provided, but the treatments are inadequate for effectively addressing diseases like cancer due to insufficient immune modulation or targeting

Engineering Contradiction:
Improveeffectiveness of immune modulationVSAvoidtargeting capability of infected and cancerous cells
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent combines IL-10 polypeptide with targeting moieties to create conjugates that merge immune modulation functionality with specific cancer cell targeting capability, thereby simultaneously improving both reliability of immune modulation and adaptability for targeting cancerous cells

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The invention creates composite molecular structures by conjugating IL-10 polypeptides with targeting moieties, forming a composite therapeutic agent that integrates the immunomodulatory properties of IL-10 with the targeting specificity of the conjugated moiety, enabling effective cancer treatment

Inventive Principle:
Principle #40Composite materials

2Duration of action of stationary object

If IL-10 conjugates with unnatural amino acids are developed, then plasma half-life is enhanced, but the complexity of the polypeptide structure increases

Engineering Contradiction:
Improveplasma half-life of IL-10VSAvoidpolypeptide structure complexity
Core Design Contradiction:
Duration of action of stationary objectVSDevice complexity

Solution Approach 1:

The patent introduces unnatural amino acids with specific chemical parameters (such as PEGylation-capable residues) into the IL-10 polypeptide structure, changing the physical-chemical parameters of the molecule to enhance plasma half-life while maintaining a relatively simple and systematic structural modification approach

Inventive Principle:
Principle #35Parameter changes
