Who holds the patent for Darolutamide?

Introduction to Darolutamide

Overview of Darolutamide
Darolutamide is a novel nonsteroidal androgen receptor inhibitor (ARi) that has been clinically developed to treat prostate cancer. With its distinct chemical structure, darolutamide binds with high affinity to androgen receptors, blocking the receptor signal transduction and preventing the growth of malignant prostate cells. Its development represents a significant milestone in the treatment landscape of both non-metastatic castration-resistant prostate cancer (nmCRPC) and metastatic hormone-sensitive prostate cancer (mHSPC). Darolutamide’s attributes include a low propensity for central nervous system (CNS) penetration, which is associated with a reduced incidence of CNS-related adverse events compared to other AR inhibitors. This characteristic is supported by both preclinical models and clinical trials, making darolutamide an attractive option for patients who might otherwise experience side effects from competing therapies.

Clinical Uses and Benefits
Clinically, darolutamide has established its efficacy in extending metastasis-free survival and overall survival. In pivotal clinical trials such as ARAMIS and ARASENS, darolutamide demonstrated significant antitumor activity in men with nmCRPC and mHSPC, respectively. The ARAMIS trial, in particular, provided robust evidence for its role in delaying metastasis while maintaining a favorable safety profile. Additionally, its use in combination strategies—such as with androgen deprivation therapy (ADT) and chemotherapy with docetaxel—has expanded its application in various stages of prostate cancer treatment. The favorable pharmacokinetic and pharmacodynamic properties of darolutamide ensure that it not only improves patient outcomes but also minimizes risks typically associated with CNS effects, thereby improving overall quality of life.

Patent Information

Definition and Importance of Drug Patents
Drug patents are legal protections granted by governments worldwide that confer the exclusive right to develop, manufacture, and market a novel pharmaceutical compound for a fixed period. These patents are critical for the pharmaceutical industry as they serve several essential functions:
- Innovation Incentives: They encourage research and development by providing the patent holder with a temporary monopoly, allowing the recovery of the often astronomical costs associated with drug discovery and development.
- Knowledge Dissemination: Patents require the detailed disclosure of the invention, thereby enriching the scientific community’s publicly available knowledge base and fostering subsequent innovation.
- Market Exclusivity: They create a period during which generics or alternative competing products are legally excluded from the market, thus ensuring a competitive advantage that can translate into significant economic returns for the innovator.

Patent Lifecycle and Legal Aspects
The lifecycle of a drug patent typically begins at the time of application, followed by prosecution and eventual grant. Once granted, a patent remains in force for up to 20 years, during which the patent owner has the exclusive right to market and profit from the invention. However, various legal aspects can affect this period, including regulatory review times, litigation challenges, or potential licensing agreements. Patents can also be extended or modified through supplementary filings that cover specific formulations, methods of use, manufacturing processes, or even polymorphic forms of the compound. These legal strategies help extend market exclusivity and protect the innovative features of the drug beyond its original patent filing, making patent management a complex yet vital part of pharmaceutical commercialization.

Darolutamide Patent Details

Current Patent Holder
From the perspective of the structured synapse references, it is clear that darolutamide is associated with multiple patent filings held by various entities. However, a dominant recurring name in key patents related to darolutamide is Orion Corporation. This company appears as the current assignee in several pivotal patents that pertain to the pharmaceutical composition, solid-state forms, crystalline forms, and even the drug product involving darolutamide.
- For instance, patents such as those described in references consistently attribute the current assignee status to Orion Corporation. The patent descriptions indicate that darolutamide or its pharmaceutically acceptable salts are primarily formulated for oral administration, presenting secure binding properties and efficacy in AR modulation. This demonstrates that Orion Corporation not only holds the intellectual property rights related to the core compound but also has a significant stake in its formulation and therapeutic application.
- It is important, however, to recognize that while Orion Corporation is the predominant patent holder for the primary composition of darolutamide, other companies have also filed patents surrounding its formulation, specific delivery mechanisms, and methods of manufacturing. For example, a patent lists ALEMBIC PHARMACEUTICALS LIMITED as a current assignee for a patent on a solid oral pharmaceutical composition comprising darolutamide. Additional patents, such as those related to the preparation process from DR. REDDY’S LABORATORIES LIMITED, specialized crystalline forms from SANDOZ AG, and innovative drug implant devices involving ALESSA THERAPEUTICS, INC. and THE REGENTS OF THE UNIVERSITY OF CALIFORNIA, indicate that multiple players are active in securing intellectual property rights around various aspects of the drug’s lifecycle.
- Despite these multiple filings, when the question is focused on the patent for darolutamide itself – that is, the primary intellectual property rights covering the active compound and its main pharmaceutical composition – Orion Corporation emerges as the key patent holder based on the repeated evidence in the synapse data structure. This emphasizes Orion Corporation’s central role in the development and subsequent commercialization of darolutamide.

Patent Registration and Approval Dates
Understanding the timeline of patent registration and approval is critical for appreciating the strength and duration of market exclusivity granted to darolutamide.
- Patents from Orion Corporation share common application dates (for instance, around July 2020 in some cases) and subsequent publication dates in early 2021. This timeline not only aligns with the clinical development phases of darolutamide but also reinforces the fact that the intellectual property was secured in anticipation of a comprehensive global clinical strategy.
- Other patents, such as those by ALEMBIC PHARMACEUTICALS LIMITED and DR. REDDY’S LABORATORIES LIMITED, reflect more recent application dates (for example, as late as 2023–2024), suggesting that these patents may cover innovations in formulation techniques or novel production processes that build upon the initial patent framework established by Orion Corporation.
- The diversity in registration dates across various patents emphasizes that while Orion Corporation’s patents represent the foundational intellectual property for darolutamide, subsequent filings by other companies ensure that any improvements or alternative formulations are also legally secured. This tiered approach to patenting helps maximize the protection covering both the original compound and its derivatives or alternative delivery systems.
