Solution Overview

Problem

Current treatments lack effective solutions for lysosomal storage disorders and disorders characterized by lysosomal dysfunction, with no cures or approved treatments available for conditions like Batten disease, and existing drug development challenges due to insufficient understanding of the in vivo pathways regulating TFEB and the CLEAR network.

Innovation Solution

Administration of a therapeutically effective amount of a composition comprising a protein kinase B inhibitor, such as trehalose or MK-2206, to inhibit AKT, thereby activating the CLEAR gene network and enhancing lysosomal clearance, which includes using trehalose alone or in combination with a trehalase inhibitor like miglustat.

Engineering Contradictions & Design Principles

VSEngineering Contradiction Analysis

1Reliability

If no treatment is administered for lysosomal storage disorders, then the natural progression of the disease continues with accumulation of undegraded materials, but current available treatments also fail to effectively clear these materials and provide cure

Engineering Contradiction:
Improveeffectiveness of treatmentVSAvoidaccumulation of undegraded materials
Core Design Contradiction:
ReliabilityVSObject-generated harmful factors

Solution Approach 1:

The patent changes the biochemical parameter of AKT activity through inhibition, which triggers a cascade effect leading to increased lysosomal clearance. By modifying the activity state of AKT (from active to inhibited), the system transitions to a state where lysosomal degradation is enhanced, thereby clearing undegraded materials that accumulate in lysosomal storage disorders

Inventive Principle:
Principle #35Parameter changes

Solution Approach 2:

The patent introduces AKT as an intermediary regulator between cellular metabolism and lysosomal function. By targeting AKT with inhibitors, the treatment indirectly activates the CLEAR network and enhances lysosomal clearance without directly modifying the defective lysosomal enzymes, thus providing a novel therapeutic approach

Inventive Principle:
Principle #24Intermediary (Mediator)

2Ease of manufacture

If drug development targets TFEB and CLEAR network directly, then potential treatment efficacy may be achieved, but the insufficient understanding of in vivo pathways regulating TFEB makes drug development challenging

Engineering Contradiction:
Improvedrug development feasibilityVSAvoidunderstanding of regulatory pathways
Core Design Contradiction:
Ease of manufactureVSLoss of information

Solution Approach 1:

The patent uses AKT as an upstream intermediary that connects to the TFEB-CLEAR network. By targeting AKT instead of directly targeting TFEB or the CLEAR network, the invention provides a more accessible drug development target with better understood pharmacology, while still achieving the desired effect of enhancing lysosomal clearance through the AKT-TFEB pathway

Inventive Principle:
Principle #24Intermediary (Mediator)

Solution Approach 2:

The patent performs preliminary action by inhibiting AKT upstream in the signaling pathway, which subsequently leads to activation of TFEB and the CLEAR network. This upstream intervention simplifies drug development by targeting a well-characterized kinase with existing inhibitor tools, rather than attempting to directly modulate the less understood TFEB regulation mechanisms

Inventive Principle:
Principle #10Preliminary action
