Solution Overview

Problem

Current therapies for Huntington's Disease (HD) only manage symptoms and do not slow the progression of the disease, with no approved therapeutics available to modify the disease course.

Innovation Solution

A tablet formulation containing 2-[3-(2,2,6,6-tetramethylpiperidin-4-yl)-3H-[1,2,3]triazolo[4,5-c]pyridazin-6-yl]-5-(2H-1,2,3-triazol-2-yl)phenol (Compound 1) as an active ingredient, combined with specific excipients, is developed to potentially slow the progression of HD by reducing HTT production and altering mRNA splicing.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If current symptomatic therapies are used for Huntington's Disease, then symptom management is achieved, but disease progression cannot be slowed

Engineering Contradiction:
Improvedisease progression controlVSAvoidtherapeutic availability
Core Design Contradiction:
ReliabilityVSEase of manufacture

Solution Approach 1:

The patent applies parameter changes by modifying the splicing pattern of HTT mRNA through small molecule compound intervention. The compound alters the molecular parameters of mRNA processing to produce an in-frame stop codon, thereby changing the biological outcome from progressive disease to disease modification without requiring complex manufacturing processes

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent uses small molecule compounds as intermediaries to mediate between the HTT gene and the resulting protein production. These compounds act as splicing modulators that intervene in the mRNA processing pathway, serving as a bridge to achieve disease modification through a manageable therapeutic mechanism

Inventive Principle:
Principle #24Intermediary (Mediator)

2Reliability

If small molecule disease-modifying therapies are developed, then disease progression can be slowed, but manufacturing and formulation complexity increases

Engineering Contradiction:
Improvedisease modification capabilityVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

The patent utilizes parameter changes in the molecular structure of small molecule compounds to achieve disease modification. By designing compounds with specific structural parameters that target splicing machinery, the patent achieves therapeutic effect through relatively simple molecular entities that can be formulated as standard tablets

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent applies local quality by designing small molecule compounds with specific functional groups and structural features localized to interact with splicing components. This targeted local molecular design achieves disease modification without requiring complex overall formulation structures

Inventive Principle:
Principle #3Local quality
