Solution Overview

Problem

Current treatments for CFTR-mediated diseases, such as cystic fibrosis, are inadequate, particularly for patients with residual CFTR activity, as they fail to effectively modulate CFTR activity to improve ion and fluid transport across epithelial tissues, leading to persistent respiratory and gastrointestinal issues.

Innovation Solution

Pharmaceutical compositions containing N-[2,4-bis(1,1-dimethylethyl)-5-hydroxyphenyl]-1,4-dihydro-4-oxoquinoline-3-carboxamide (Compound 1) are developed, combined with suitable liquid PEG and optionally a viscosity enhancing agent, to modulate CFTR activity in the cell membrane, thereby treating or lessening the severity of CFTR-mediated diseases.

2Reliability

If Compound 1 is combined with liquid PEG and viscosity enhancing agent, then CFTR activity is effectively modulated, but the formulation complexity increases

Engineering Contradiction:
ImproveCFTR activity modulationVSAvoidformulation complexity
Core Design Contradiction:
ReliabilityVSDevice complexity

Solution Approach 1:

Liquid PEG serves as an intermediary carrier that facilitates the delivery and absorption of Compound 1. The PEG acts as a mediating substance that enhances the bioavailability and effectiveness of the active compound while managing the formulation's physical properties. The optional viscosity enhancing agent further mediates the formulation's rheological characteristics to optimize delivery.

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The formulation utilizes parameter changes in the physical and chemical properties of the excipients to optimize drug delivery. By adjusting the molecular weight and viscosity of PEG, and selecting appropriate viscosity enhancing agents, the formulation achieves optimal balance between stability, bioavailability, and ease of administration, thereby enhancing CFTR modulation effectiveness without excessive complexity.

Inventive Principle:
