Solution Overview

Problem

There is a need for particularly effective combinations of drugs for the treatment of specific types of cancer, particularly in addressing cancer cells resistant to therapy.

Innovation Solution

A combination therapy involving a compound of Formula I, which includes a phosphoinositide 3-kinase inhibitor with a zinc binding moiety, and a PD-1 signaling inhibitor, such as pembrolizumab or nivolumab, is administered to treat cancers, with the compounds being administered separately or simultaneously via various routes to achieve synergistic therapeutic effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If combination therapy with multiple agents is used to treat cancer, then therapeutic effectiveness is improved, but treatment complexity increases

Engineering Contradiction:
Improvetherapeutic effectivenessVSAvoidtreatment complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines a phosphoinositide 3-kinase inhibitor (Compound 1) with a PD-1 signaling inhibitor in a unified treatment protocol. This merging of two distinct therapeutic agents into a coordinated combination therapy enhances anti-tumor effectiveness by targeting multiple pathways simultaneously while managing the complexity through structured administration guidelines

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If combination therapy is used to address resistant cancer cells, then treatment efficacy is improved, but safety risks increase

Engineering Contradiction:
Improvetreatment efficacyVSAvoidsafety risks
Core Design Contradiction:
ReliabilityVSObject-affected harmful factors

Solution Approach 1:

The patent employs parameter changes by adjusting the dosing levels and administration timing of both Compound 1 and the PD-1 inhibitor. This allows optimization of the therapeutic window, maintaining high efficacy against resistant cancer cells while managing safety risks through controlled exposure levels

Inventive Principle:
Principle #35Parameter changes

3Productivity

If multiple drugs are administered simultaneously, then therapeutic impact is enhanced, but administration complexity increases

Engineering Contradiction:
Improvetherapeutic impactVSAvoidadministration ease
Core Design Contradiction:
ProductivityVSEase of operation

Solution Approach 1:

The patent segments the administration protocol into distinct components with specific timing and routing instructions for Compound 1 and the PD-1 inhibitor. This segmentation allows each drug to be optimized for its own delivery while maintaining coordinated therapeutic impact, reducing administration complexity through structured protocols

Inventive Principle:
Principle #1Segmentation
