This technical disclosure describes improvements that would be readily apparent to a Person Having Ordinary Skill In The Art (PHOSITA) when considered in combination with the foundational architecture disclosed in U.S. Patent No. 11,857,549.

Summary of the Inventive Concept

The inventive concept expands the therapeutic potential of RhoA inhibitors and mTOR inhibitors beyond Lowe Syndrome to address unmet needs in chronic skin conditions, muscle atrophy, neurodegenerative diseases, wound healing, and respiratory diseases.

Background and Problem Solved

The original patent disclosed the use of RhoA inhibitors, statins, and mTOR inhibitors for the treatment of Lowe Syndrome. However, the full therapeutic potential of these compounds remains untapped. The inventive concept addresses the limitations of the original patent by exploring new applications and use cases for these compounds, providing novel solutions for underserved diseases and conditions.

Detailed Description of the Inventive Concept

The inventive concept comprises four primary embodiments: (1) a system for treating chronic skin conditions using topical compositions of RhoA inhibitors and mTOR inhibitors, (2) a method for reducing muscle atrophy in astronauts during space travel via pharmaceutical compositions of RhoA inhibitors and statins, (3) a composition for treating neurodegenerative diseases by combining RhoA inhibitors, mTOR inhibitors, and neuroprotective agents, and (4) a system for enhancing wound healing using biodegradable matrices containing RhoA inhibitors and mTOR inhibitors. These embodiments leverage the synergistic effects of RhoA inhibitors and mTOR inhibitors to address specific disease mechanisms and pathways.

Novelty and Inventive Step

The inventive concept introduces new and non-obvious applications of RhoA inhibitors and mTOR inhibitors, departing from the original patent's focus on Lowe Syndrome. The combination of these compounds with other therapeutic agents and their application to diverse disease areas constitutes a novel and inventive step.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept could include the use of different RhoA inhibitors or mTOR inhibitors, varying the dosage and administration routes, or combining these compounds with other therapeutic agents to address specific disease mechanisms. Additionally, the inventive concept could be adapted for use in veterinary medicine or in conjunction with other treatment modalities, such as gene therapy or stem cell therapy.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the pharmaceutical and biotechnology industries, with potential applications in dermatology, neurology, respiratory medicine, and space medicine. The target market includes patients suffering from chronic skin conditions, muscle atrophy, neurodegenerative diseases, and respiratory diseases, as well as astronauts and individuals at risk of developing these conditions.

Field of Art

Pharmaceutical biotechnology with a focus on targeted therapeutic interventions for genetic and degenerative disorders, involving pharmacological modulation of cellular signaling pathways

Person of Ordinary Skill (PHOSITA) Profile

A researcher or pharmaceutical scientist with advanced degrees in molecular biology or pharmacology, experienced in drug development, signal transduction mechanisms, and therapeutic compound design, familiar with RhoA, mTOR, and statin biochemical interactions

Obviousness Rationale

A PHOSITA would recognize the inherent potential for expanding the therapeutic applications of RhoA and mTOR inhibitors beyond Lowe Syndrome, given the known pleiotropic effects of these molecular targets. The source patent establishes the fundamental pharmacological mechanism of combining RhoA inhibitors and mTOR modulators, which naturally suggests broader therapeutic potential across multiple disease states. The PTD's variations represent logical extensions of the original patent's core scientific insights, applying well-understood molecular targeting strategies to address diverse pathological conditions.
