Solution Overview

Problem

Current CAR-T cell therapies for cancer, such as those targeting CD19, face challenges in specificity and efficacy due to varying structures and production methods, and there is a need for effective treatments for cancers expressing ROR-1 antigen.

Innovation Solution

Development of chimeric antigen receptors (CARs) specifically targeting ROR-1, comprising an antigen binding region, spacer domain, transmembrane domain, and intracellular signaling domains, optimized for improved function and expressed in T lymphocytes for therapeutic use.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Adaptability or versatility

If multiple different CAR structures and production methods are used to treat various cancers, then the versatility and coverage of cancer treatment is improved, but the complexity of pharmacology and manufacturing increases

Engineering Contradiction:
Improvecancer treatment coverageVSAvoidpharmacology complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent develops CAR structures with universal design elements that can target multiple cancer-associated antigens including ROR-1, CD19, and other markers. The standardized modular CAR architecture allows a single platform to be adapted for treating diverse cancers through antigen-specific variable regions, thereby improving treatment versatility while maintaining consistent manufacturing and pharmacological principles across different cancer types.

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

2Reliability

If CAR-T cells are optimized with specific spacer lengths and signaling domains to improve function, then the therapeutic efficacy is improved, but the manufacturing precision requirements increase

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoidCAR structure precision
Core Design Contradiction:
