Solution Overview

Problem

Existing combinations of ICG001 and MEK inhibitors do not provide sufficient suppression of tumor growth, and there is a lack of known therapies involving the compound represented by formula (I) and MEK inhibitors.

Innovation Solution

The combined administration of (6S,9aS)-N-benzyl-8-({6-[3-(4-ethylpiperazin-1-yl)azetidin-1-yl]pyridin-2-yl}methyl)-6-(2-fluoro-4-hydroxybenzyl)-4,7-dioxo-2-(prop-2-en-1-yl)hexahydro-2H-pyrazino[2,1-c][1,2,4]triazine-1(6H)-carboxamide or its pharmaceutically acceptable salts with MEK inhibitors, such as Trametinib, enhances antitumor effects.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If ICG001 and MEK inhibitor are used in combination, then antitumor effect is enhanced compared to single administration, but the suppression effect is still not sufficient

Engineering Contradiction:
Improveantitumor effectVSAvoidtumor growth
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the chemical parameter by replacing ICG001 with a structurally modified compound (formula I) that has enhanced Wnt pathway inhibition capability. This parameter change in the inhibitor's molecular structure leads to improved antitumor efficacy when combined with MEK inhibitors, resolving the insufficiency of the ICG001+MEK inhibitor combination.

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent creates a composite therapeutic approach by combining a Wnt pathway inhibitor (formula I) with a MEK inhibitor. This composite therapy targets two different signaling pathways (Wnt and RAS-RAF-MEK-ERK) simultaneously, achieving synergistic antitumor effects that overcome the limitations of single-pathway or previous combination therapies.

Inventive Principle:
Principle #40Composite materials

2Adaptability or versatility

If there is no known combination therapy using compound (I) and MEK inhibitor, then treatment options are limited, but developing new combinations increases complexity

Engineering Contradiction:
Improvetreatment optionsVSAvoidcombination therapy complexity
Core Design Contradiction:
Adaptability or versatilityVSDevice complexity

Solution Approach 1:

The patent segments the cancer therapy approach by separately targeting the Wnt pathway (with compound I) and the RAS-RAF-MEK-ERK pathway (with MEK inhibitor). This segmentation allows each component to be optimized independently while maintaining manageable complexity in the overall combination therapy regimen.

Inventive Principle:
Principle #1Segmentation
