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. 11,857,567.

Summary of the Inventive Concept

The present inventive concept integrates the patented hypertonic pharmaceutical compositions containing an anti-platinum chemoprotectant agent with distinct technologies, such as AI, IoT, blockchain, and new materials, to create a more powerful system for preventing platinum-induced ototoxicity.

Background and Problem Solved

The original patent addresses the issue of platinum-based antineoplastic agents inducing hearing loss in patients undergoing chemotherapy. However, it only provides pharmaceutical compositions containing an anti-platinum chemoprotectant agent. The new inventive concept addresses the limitation of the original patent by combining these compositions with other technologies to provide a more comprehensive solution for preventing platinum-induced ototoxicity.

Detailed Description of the Inventive Concept

The new inventive concept involves the integration of the patented hypertonic pharmaceutical compositions with AI-powered monitoring devices, blockchain technology, IoT-enabled devices, and nanoparticle-based delivery systems incorporating new materials. For example, a system for preventing platinum-induced ototoxicity in a subject may comprise a hypertonic pharmaceutical composition containing an anti-platinum chemoprotectant agent, and an AI-powered monitoring device for tracking sound pressure level threshold elevation in the subject. Alternatively, a method for mitigating hearing loss in a subject receiving a platinum-based antineoplastic agent may comprise administering a hypertonic pharmaceutical composition containing an anti-platinum chemoprotectant agent, and using blockchain technology to securely store and track the subject's treatment regimen.

Novelty and Inventive Step

The new inventive concept is novel and non-obvious because it combines the patented hypertonic pharmaceutical compositions with distinct technologies, such as AI, IoT, blockchain, and new materials, to create a more powerful system for preventing platinum-induced ototoxicity. The integration of these technologies provides a synergistic effect that is not obvious from the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept may include the use of different AI algorithms for monitoring sound pressure level threshold elevation, the incorporation of additional sensors in the IoT-enabled device, or the use of different nanoparticle-based delivery systems. Variations of the inventive concept may include the use of different chemoprotectant agents or the integration of additional technologies, such as machine learning algorithms for optimizing dosing regimens.

Potential Commercial Applications and Market

The inventive concept has significant commercial potential in the pharmaceutical industry, particularly in the development of treatments for platinum-induced ototoxicity. The integration of distinct technologies provides a unique selling point and may attract investors and partners. The target market includes pharmaceutical companies, hospitals, and clinics that provide chemotherapy treatment to patients.
