Solution Overview

Problem

Current cancer treatments, particularly those involving platinum-based drugs, face challenges such as drug resistance, severe side effects, and the need for new efficacious combination therapies.

Innovation Solution

The development of a pharmaceutical combination comprising anti-LY75 antibodies or antigen-binding portions thereof, in conjunction with platinum-based antineoplastic drugs, demonstrating synergistic results in treating cancers mediated by LY75 expression or activity.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If platinum-based drugs (cisplatin, carboplatin, oxaliplatin) are used for cancer treatment, then therapeutic efficacy is improved, but drug resistance develops and severe side effects occur

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoidside effects and drug resistance
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent combines anti-LY75 antibodies with platinum-based drugs to create a combination therapy that synergistically enhances anticancer efficacy while overcoming drug resistance. The antibody targets LY75-expressing cancer cells specifically, and when combined with platinum drugs, achieves greater therapeutic effect than either agent alone, thereby improving reliability while mitigating the development of resistance

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The anti-LY75 antibody provides localized targeting to cancer cells that express the LY75 antigen, concentrating the therapeutic effect at the tumor site. This localized action enhances efficacy at the target while reducing systemic exposure and thereby decreasing severe side effects such as kidney problems, hearing loss, and gastrointestinal disorders

Inventive Principle:
Principle #3Local quality

2Reliability

If cisplatin is used at high doses to overcome resistance, then therapeutic efficacy is improved, but toxicity increases significantly

Engineering Contradiction:
Improvetherapeutic efficacyVSAvoidtoxicity
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The combination of anti-LY75 antibodies with platinum-based drugs creates a synergistic effect that allows for enhanced therapeutic efficacy at lower doses of the platinum drug. The antibody component contributes to the anticancer activity, enabling dose reduction of the toxic platinum agent while maintaining or improving overall efficacy

Inventive Principle:
Principle #5Merging (Combining)

Solution Approach 2:

The anti-LY75 antibody acts as an intermediary that enhances the anticancer effect of platinum drugs through targeted delivery and synergistic mechanism. The antibody binds to LY75 on cancer cells and facilitates the therapeutic action, allowing the platinum drug to work more efficiently at lower concentrations, thereby reducing toxicity

Inventive Principle:
Principle #24Intermediary (Mediator)

3Reliability

If combination chemotherapy with multiple drugs is used, then resistance development is minimized, but treatment complexity increases

Engineering Contradiction:
Improveresistance preventionVSAvoidtreatment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines two distinct therapeutic agents with different mechanisms of action: anti-LY75 antibodies that target cancer cells expressing the LY75 antigen and platinum-based drugs that damage DNA. This combination minimizes resistance development through mechanism diversity while maintaining relatively simple treatment protocols

Inventive Principle:
Principle #5Merging (Combining)
