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. 11,857,529.

Summary of the Inventive Concept

The present inventive concept relates to improved methods for treating melanoma by administering dapansutrile in combination with nanoparticle delivery systems, anti-PD-1 antibodies, matrix metalloproteinase inhibitors, or anti-IL-1β antibodies to enhance efficacy, reduce side effects, and improve patient outcomes.

Background and Problem Solved

The original patent for treating melanoma with dapansutrile has limitations, such as limited bioavailability, inadequate tumor targeting, and potential side effects. The present inventive concept addresses these limitations by introducing novel formulations and combinations that improve the efficacy and safety of dapansutrile-based treatments.

Detailed Description of the Inventive Concept

The inventive concept comprises a dapansutrile-based composition and a nanoparticle delivery system for targeted delivery to tumor sites, enhancing bioavailability and reducing systemic toxicity. Alternatively, the inventive concept involves co-administering dapansutrile with an anti-PD-1 antibody to enhance immune response, or with a matrix metalloproteinase inhibitor to reduce tumor invasion. Additionally, the inventive concept includes a pharmaceutical composition comprising dapansutrile and an anti-IL-1β antibody to reduce inflammation and improve treatment outcomes. These combinations and formulations improve the efficacy of dapansutrile in treating melanoma, reducing the production of myeloid-derived suppressor cells and enhancing patient outcomes.

Novelty and Inventive Step

The present inventive concept introduces novel combinations and formulations of dapansutrile that are not obvious from the original patent. The use of nanoparticle delivery systems, anti-PD-1 antibodies, matrix metalloproteinase inhibitors, and anti-IL-1β antibodies in combination with dapansutrile provides a new and non-obvious solution to the limitations of the original patent.

Alternative Embodiments and Variations

Alternative embodiments of the inventive concept include using different types of nanoparticle delivery systems, such as liposomes or micelles, or combining dapansutrile with other immunotherapies or targeted therapies. Variations of the inventive concept may also include using different dosing regimens, administration routes, or treatment schedules to optimize patient outcomes.

Potential Commercial Applications and Market

The present inventive concept has significant commercial potential in the treatment of melanoma, a market projected to reach $12.4 billion by 2025. The inventive concept's improved efficacy and safety profile make it an attractive option for patients and healthcare providers, with potential applications in both early-stage and late-stage melanoma treatment.

Field of Art

Oncology, pharmaceutical composition design, and melanoma treatment strategies, with expertise in drug delivery systems, immunotherapeutic approaches, and targeted cancer interventions

Person of Ordinary Skill (PHOSITA) Profile

A skilled practitioner with advanced degrees in pharmacology or oncology, familiar with cancer treatment methodologies, combination therapy strategies, and drug delivery optimization techniques

Obviousness Rationale

A person skilled in the art would recognize that enhancing dapansutrile's melanoma treatment efficacy through targeted delivery systems and combination therapies represents a predictable extension of the source patent's foundational treatment method. The proposed variations leverage known oncological strategies for improving drug performance and patient outcomes. These modifications demonstrate standard approaches in cancer therapeutics for optimizing existing pharmaceutical interventions.
