TNO155–Ribociclib Combination for Extended Tumor Control

Solution Overview

Problem

Current treatments for cancers such as esophageal, head and neck squamous cell carcinoma, colorectal, ovarian, pancreatic, non-small cell lung cancer, and renal cell carcinoma are limited in efficacy, with existing therapies often leading to disease progression within a year.

Innovation Solution

The combination of TNO155, an allosteric inhibitor of SHP2, and ribociclib, a CDK4/6 inhibitor, is administered to target the SHP2 and CDK4/6 pathways, thereby inhibiting cancer cell proliferation and halting cell cycle progression.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If single-agent therapy is used, then treatment simplicity is maintained, but efficacy is limited and disease progression occurs within a year

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent combines TNO155 (SHP2 inhibitor) and ribociclib (CDK4/6 inhibitor) into a fixed-ratio combination therapy, merging two distinct molecular mechanisms to achieve synergistic anti-tumor effects. This combination targets both upstream (SHP2) and downstream (CDK4/6) components of the RTK-RAS-MAPK and cell cycle pathways, thereby improving treatment efficacy while managing complexity through fixed-dose formulation.

Inventive Principle:
Principle #5Merging (Combining)

2Reliability

If combination therapy is used, then efficacy is improved, but treatment complexity increases

Engineering Contradiction:
Core Design Contradiction:
ReliabilityVSEase of operation

Solution Approach 1:

The patent develops a fixed-ratio combination product that integrates TNO155 and ribociclib in predetermined proportions, allowing simultaneous administration of both agents in a single therapeutic regimen. This approach simplifies the operational aspects of combination therapy by eliminating the need for separate dosing schedules and administration procedures.

Inventive Principle:
Principle #5Merging (Combining)

3Duration of action of moving object

If existing therapies are used, then treatment accessibility is maintained, but time to disease progression is short

Engineering Contradiction:
Core Design Contradiction:
Duration of action of moving objectVSReliability

Solution Approach 1:

The patent employs preliminary action by inhibiting SHP2 upstream in the signaling pathway before it can activate downstream effectors including CDK4/6. This preemptive inhibition of the phosphatase activity prevents full activation of proliferative signaling, thereby extending the time to tumor progression and improving treatment effectiveness.

Inventive Principle:
Principle #10Preliminary action

Solution Approach 2:

The patent segments the anti-cancer therapy into two distinct but complementary mechanisms: SHP2 inhibition (upstream signaling blockade) and CDK4/6 inhibition (downstream cell cycle blockade). This segmentation allows each component to address specific nodes in the cancer signaling pathway, achieving more durable disease control than single-agent therapy.

Inventive Principle:
Principle #1Segmentation
