Solution Overview

Problem

Current cancer therapies, including surgeries, chemotherapies, and immune therapies, often yield unsatisfactory outcomes, necessitating the development of more effective therapies and prophylactic regimens for treating cancers, particularly those that target B-cell maturation antigen (BCMA) and Transmembrane activator and CAML interactor (TACI).

Innovation Solution

Immunogenic peptides specific to BCMA and TACI, administered alone or in combination with immune modulators, checkpoint inhibitors, and adjuvants, to stimulate cytotoxic T cells (CTLs) and induce targeted immune responses against BCMA- and TACI-expressing cancer cells.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If conventional cancer therapies (surgeries, chemotherapies, immune therapies) are used, then treatment coverage is broad, but therapeutic efficacy is unsatisfactory

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoidtreatment coverage
Core Design Contradiction:
ReliabilityVSAdaptability or versatility

Solution Approach 1:

The patent segments the cancer treatment approach by identifying and targeting specific antigens (BCMA and TACI) that are uniquely expressed on cancer cells. This segmentation allows for targeted peptide-based vaccines that focus immune responses on specific cancer cell populations, thereby improving therapeutic efficacy while maintaining the ability to address different cancer types expressing these antigens.

Inventive Principle:
Principle #1Segmentation

Solution Approach 2:

The invention applies local quality by designing peptides with specific amino acid sequences that bind to MHC molecules and present antigenic determinants unique to BCMA and TACI-expressing cancer cells. This localized targeting ensures that immune responses are directed specifically at cancer cells with the desired antigen expression, improving efficacy without compromising broader treatment applicability.

Inventive Principle:
Principle #3Local quality

2Reliability

If immunogenic peptides specific to BCMA and TACI are used, then immune recognition of cancer cells is enhanced, but treatment complexity increases

Engineering Contradiction:
Improveimmune recognition efficacyVSAvoidtreatment regimen complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent extracts the essential antigenic components by identifying specific peptide sequences from BCMA and TACI proteins that serve as immunogenic determinants. These extracted peptide sequences are then used to create simplified vaccine formulations that focus on the most critical antigenic regions, enhancing immune recognition while avoiding the complexity of using entire protein structures.

Inventive Principle:
Principle #2Taking out (Extraction)

Solution Approach 2:

The invention employs parameter changes by modifying peptide sequences to optimize their binding affinity to MHC molecules and their immunogenicity. By carefully adjusting amino acid compositions and sequences, the patent achieves enhanced immune recognition efficacy while maintaining manageable treatment protocols that do not require excessive complexity.

Inventive Principle:
Principle #35Parameter changes

3Reliability

If peptide sequences are modified to enhance immunogenicity, then immune response is improved, but peptide specificity may be compromised

Engineering Contradiction:
Improveimmune response strengthVSAvoidpeptide sequence specificity
Core Design Contradiction:
ReliabilityVSManufacturing precision

Solution Approach 1:

The patent applies dynamics by creating multiple peptide variants with different amino acid sequences that all target the same BCMA and TACI antigens. This dynamic approach allows the immune system to encounter multiple epitopes from the same antigen, strengthening the overall immune response while maintaining specificity through the common target antigen. The invention provides flexibility in peptide selection based on individual patient needs and immune responses.

Inventive Principle:
Principle #15Dynamics
