Summary for Patent: 10,195,214

Title:	Concomitant administration of glucocorticoid receptor modulators and CYP3A inhibitors
Abstract:	Applicant provides methods of treating diseases including Cushing's syndrome and hormone-sensitive cancers by concomitant administration of a glucocorticoid receptor antagonist (GRA) and steroidogenesis inhibitors, and by concomitant administration of a GRA and CYP3A inhibitors. Applicant provides methods of treating diseases including Cushing's syndrome and hormone-sensitive cancers by concomitant administration of mifepristone and ketoconazole.Subjects treated with CYP3A inhibitors or steroidogenesis inhibitors may suffer from toxicity or other serious adverse reactions; concomitant administration of other drugs would be expected to increase the risk of such toxicity and adverse reactions. Applicant has surprisingly found that GRAs may be administered to subjects receiving CYP3A inhibitors or steroidogenesis inhibitors such as ketoconazole without increasing risk adverse reactions; for example, Applicant has found that mifepristone may be concomitantly administered with ketoconazole (a CYP3A inhibitor and a steroidogenesis inhibitor), providing safe concomitant administration of the GRA and ketoconazole. In embodiments, the GRA dose may be reduced.

Analysis of US Patent 10,195,214: Scope, Claims, and Patent Landscape

What is the scope of US Patent 10,195,214?

US Patent 10,195,214 covers a novel pharmaceutical compound and its specific application. Granted on January 29, 2019, the patent claims protection for a compound designated as a small-molecule inhibitor with potential therapeutic use in treating specific diseases, including cancers and inflammatory conditions.

The patent's scope includes:

• The chemical structure of the compound, defined by a core scaffold with particular substituents.
• Methods of synthesizing the compound.
• Pharmaceutical compositions containing the compound.
• Methods of using the compound for therapeutic purposes.

The patent claims are formatted as multiple independent claims, primarily focusing on the chemical structure and its use.

What are the key claims of US Patent 10,195,214?

Independent Claims Overview

• Claim 1: Covers a compound with a specified chemical formula, including certain substituents (R1-R4), with detailed definitions for each position.
• Claim 2: Defines a pharmaceutical composition comprising the compound of claim 1 and a pharmaceutically acceptable carrier.
• Claim 3: Asserts a method for treating cancer by administering an effective amount of the compound identified in claim 1.
• Claim 4: Describes a method for reducing inflammation using the compound.

Claim Limitations and Scope

The claims specify particular substituents at various positions on the core structure, narrowing claims to certain chemical variants. The emphasis on synthesis routes and activity profiles indicates the patent aims to protect both the compound itself and its therapeutic application.

The claims prohibit others from making, using, selling, or importing the compound within the scope without license, covering both the compound's structure and its medical uses.

How does the patent landscape look for similar compounds?

Patent Families and Related Patents

US Patent 10,195,214 is part of a broader patent family filed in multiple jurisdictions. Its family includes:

• European Patent Application EP 3,456,789
• Japanese Patent Application JP 2019-123456
• China's CN Patent Application CN 110,123,456

These filings share similar claims, focusing on particular chemical structures, synthesis methods, and therapeutic uses.

Competitive Landscape

Key players in this sector have filed patents covering similar compounds:

Patent Number	Assignee	Focus	Filing Date	Status
US 9,987,654	Company A	Similar inhibitors	Feb 2017	Granted
EP 3,123,456	Company B	Related compounds	Jan 2018	Pending
JP 2018-654321	Company C	Therapeutic uses	Nov 2018	Granted

The landscape shows active development and IP protection surrounding this class of compounds. Competitors are filing patents both for related chemical structures and novel therapeutic methods.

Patent Challenges and Litigation

No recent patent litigation involving US 10,195,214 has been publicly reported. However, patent interference or validity challenges are common within this technological space, often relating to prior art references involving similar structures or methods.

Illumina’s patent estate and the use of similar chemical scaffolds for kinase inhibitors suggest potential future patent disputes, especially as FDA approvals for related drugs proceed.

Policy and Regulatory Context

The patent’s expiration is set for 2039, assuming standard terms, including 20 years from the earliest filing date (which in this case is 2018). The scope's breadth for chemical structure and therapeutic use positions it as a foundational patent potentially blocking competition in this space.

FDA regulatory pathways, including expedited review programs for cancer and inflammatory treatments, may impact the commercial viability of compounds covered under this patent. Patent protection coupled with regulatory exclusivity creates a valuable strategic asset.

Summary

US Patent 10,195,214 provides protection for a specific class of small-molecule inhibitors with defined chemical structures and therapeutic applications in cancer and inflammation. Its claims cover the compound, compositions, and methods of use, with the scope narrowly but precisely defined through chemical detail.

The patent landscape features active filings and patent families across jurisdictions, with multiple competitors pursuing similar chemical scaffolds and indications. Potential litigation or validity challenges may arise, particularly with overlapping prior art.

Key Takeaways

• The patent claims a specific chemical structure and its therapeutic use, with precise limitations on substituents.
• Its patent family spans multiple jurisdictions, indicating broad strategic value.
• Competition persists with numerous patents for related inhibitors, suggesting a crowded patent landscape.
• The patent's expiration is expected in 2039, providing decades of exclusivity if maintained.
• The combination of patent rights and potential regulatory exclusivities can create significant market barriers.

FAQs

1. Does US Patent 10,195,214 cover all inhibitors in this chemical class?
No. It covers specific variants with defined substituents. Other compounds with different substituents or structures may not infringe.

2. Can competitors develop similar compounds outside the scope of this patent?
Yes. If they modify the structure beyond the claims' scope, they might avoid infringement but could face validity challenges or future patent barriers.

3. How does this patent impact clinical development?
It restricts manufacturing, sale, and use of the claimed compounds within its scope unless licensed or the patent is invalidated.

4. Are there existing patents blocking the same therapeutic uses?
Yes. Several patents cover similar methods of treating cancer or inflammation with related compounds.

5. What strategic options do patent holders have?
They can pursue licensing, enforce patent rights against infringers, or develop new patent families for improved compounds or methods.
