Who holds the patent for Teriflunomide?
Introduction to Teriflunomide
Overview of Teriflunomide
Teriflunomide is an immunomodulatory agent primarily used in the treatment of relapsing forms of multiple sclerosis (MS). It functions mainly by inhibiting dihydroorotate dehydrogenase (DHODH), which in turn decreases de novo pyrimidine synthesis. This leads to a reduction in the proliferation of activated lymphocytes—a mechanism that underpins its therapeutic benefits in autoimmune conditions such as MS. In addition to its established application in modifying MS disease activity, teriflunomide has been explored in various other therapeutic contexts, including certain autoimmune conditions and, as some recent patents suggest, even in novel indications such as primary ciliary immobility syndrome. Overall, the drug has a multifaceted profile with an established efficacy record in multiple clinical trials and real-life settings.
Uses and Applications
Teriflunomide is used primarily as a disease-modifying therapy in MS. It is available as film-coated tablets in 7 mg and 14 mg dosages and is taken orally once daily. The mechanism of action—via DHODH inhibition—not only impacts lymphocyte proliferation but also influences various immune pathways and inflammatory cascades, thereby contributing to its overall clinical effect. Moreover, novel formulations such as topical compositions have also been investigated to address other aspects like pain relief and arthritis symptoms in autoimmune conditions. Its broad range of applications speaks to the importance of teriflunomide in both traditional and innovative treatment modalities, which in turn has spurred extensive patenting activity across various jurisdictions.
Patent Information
Patent Holder Identification
The patent landscape for teriflunomide is multifaceted and reflects the complexity inherent in pharmaceutical intellectual property rights. Traditionally, the original molecule and its primary uses have been associated with Sanofi, which developed and marketed teriflunomide under the brand name Aubagio. Evidence from Chinese legal proceedings indicates that Sanofi held formulation patents covering teriflunomide tablets in China, as demonstrated by the Supreme People's Court's rulings on related patents. These patents were designed to protect the specific pharmaceutical formulations of teriflunomide that were intended to offer stability, efficacy, and improved therapeutic performance in the market.
However, it is important to note that the patent portfolio of teriflunomide is not solely confined to Sanofi’s holdings. There are several other patents concerning specific formulation aspects, manufacturing processes, and dosage forms. For example, two patent documents accessed via the Synapse database provide insight into alternative formulations:
- Patent with the number EP4382097A1 describes a film-coated tablet comprising teriflunomide that includes calcium stearate as a lubricant and specifies particle size distributions of teriflunomide. This patent is currently assigned to SANOVEL ILAC SANAYI VE TICARET A.S.
- Patent with the number WO2024112298A1 similarly describes a tablet formulation with teriflunomide and is assigned to SANOVEL ILAC SANAYI VE TICARET ANONIM SIRKETI.
These patents, held by the respective divisions of SANOVEL ILAC, reflect the layered approach often found in pharmaceutical IP portfolios. Such layers typically include the original molecule patent, followed by subsequent patents that cover improved formulations, manufacturing processes, or combination therapies. While Sanofi has held patents for the active pharmaceutical ingredient (API) and its primary uses in MS (as indicated in the invalidity rulings in China), other companies such as SANOVEL ILAC have built upon this base by developing novel formulations that aim to optimize drug performance and stability.
Additionally, there are patents that explore alternative routes of administration or therapeutic uses. For instance, patent regarding teriflunomide topical pharmaceutical compositions adds another dimension to the patent landscape even though the assignee is not explicitly noted in the extracted reference. These diverse entries contribute to a complex and interconnected IP environment where multiple entities may hold patents related to teriflunomide, depending on the specific aspect of the drug that is in question (e.g., active ingredient, formulation, use, or method of manufacture).
Patent Details and Legal Rights
The legal rights linked to teriflunomide are distributed across several patent documents and jurisdictions. Historically, Sanofi’s patents for the teriflunomide tablets were granted in several regions, including China where the formulation patents (e.g., patents ZL201510052300.9 and ZL201510052299.X) were central to their market exclusivity for Aubagio. However, these patents faced legal challenges, and Chinese court decisions invalidated them on the grounds that they did not surpass the obviousness threshold in light of prior art. Consequently, while Sanofi was originally the primary patent holder, legal and regulatory decisions can profoundly impact the strength and enforceability of these rights.
On the other hand, the formulation patents held by SANOVEL ILAC, as seen in patents, are designed to protect novel aspects of tablet formulation. These patents focus on specific ranges of particle size distribution (d (0.5) values between 1 µm and 18 µm) and formulations that utilize calcium stearate—critical parameters that ensure drug stability and bioavailability. Holding these patents means that SANOVEL ILAC has the legal right to prevent competitors from adopting the same formulation approach in jurisdictions where the patents are valid. The legal rights conferred by these patents come with defined expiration dates and are subject to challenges on grounds such as obviousness or lack of inventive step.
Thus, while the primary molecule patents for teriflunomide may be credited to Sanofi, the more specialized patent rights regarding its formulation are held by other entities such as SANOVEL ILAC. This duality exemplifies a common trend in the pharmaceutical industry, where a prominent innovator (Sanofi, in this case) may pave the way with the original discovery, and subsequent formulation and manufacturing improvements might be pursued and patented by different companies.
