Definitions
- the present invention relates to pharmaceutical compositions comprising teriflunomide and one or more pharmaceutically acceptable excipient and are used in the treatment of autoimmune diseases such as especially systemic lupus erythematosus or chronic graft- versus-host disease, multiple sclerosis or rheumatoid arthritis. More specifically, this composition is characterized in that it does not contain glidants.
- MS Multiple Sclerosis
- MS is a demyelinating disease characterized by damage to insulating ends of neurons in the brain and spinal cord. This damage impairs the communication between the components of central nervous system and leads to a series of signs and symptoms including physical, mental, and sometimes, psychiatric problems. Specific symptoms include diplopia, blindness in one eye, muscle weakness, sensory impairment or coordination problems. MS presents with new symptoms either in isolated attacks (in relapsing-remitting forms) or over time (progressively). Symptoms may completely resolve in between attacks. In addition, the likelihood of having permanent neurological damage is high especially as the disease progresses.
- Teriflunomide is a pyrimidine synthesis inhibitor. Teriflunomide acts via the mechanism of a dihydroorotate dehydrogenase inhibitor and it is an orally available immunomodulator used in the treatment of relapsing-remitting multiple sclerosis. Chemical name of teriflunomide is (Z)- 2-cyano-3-hydroxy-N-[4-(trifluoromethyl)phenyl]but-2enamide and its chemical structure is shown in Formula I.
- Teriflunomide inhibits rapidly dividing cells including activated T cells that are believed to drive the disease process in MS and it may decrease the risk of infection thanks to its more limited effects on the immune system compared to chemotherapeutic agents.
- EP0527736B1 is the first molecule patent that describes teriflunomide in the prior art. It mentions the use of teriflunomide in the prophylaxis and/or treatment of rheumatic diseases and the possibility to administer the pharmaceuticals of the invention orally, topically, rectally and parenterally, if required.

- Colloidal silicon dioxide is a fumed silica that is prepared with the hydrolysis of a silica compound. Its particle size is around 15nm and it is an amorphous powder that is odorless, tasteless and water-insoluble. Colloidal silicon dioxide can cause stability problems in pharmaceutical compositions depending on its amount therein due to its hygroscopic structure that enables absorbing a high amount of water. Colloidal silicon dioxide acts both as a lubricant and glidant in solid oral pharmaceutical compositions. Although it is frequently used in formulations due to its fluidity, the fact that it increases the rate of becoming unstable by promoting degradation and has highly humectant properties reveals the reasons for not preferring colloidal silicon dioxide especially in compositions that are sensitive to humidity.

SOLID ORAL PHARMACEUTICAL COMPOSITIONS COMPRISING TERIFLUNOMIDE
Field of the Invention
The present invention relates to pharmaceutical compositions comprising teriflunomide and one or more pharmaceutically acceptable excipient and are used in the treatment of autoimmune diseases such as especially systemic lupus erythematosus or chronic graft- versus-host disease, multiple sclerosis or rheumatoid arthritis. More specifically, this composition is characterized in that it does not contain glidants.
Background of the Invention
Multiple Sclerosis (MS) is a demyelinating disease characterized by damage to insulating ends of neurons in the brain and spinal cord. This damage impairs the communication between the components of central nervous system and leads to a series of signs and symptoms including physical, mental, and sometimes, psychiatric problems. Specific symptoms include diplopia, blindness in one eye, muscle weakness, sensory impairment or coordination problems. MS presents with new symptoms either in isolated attacks (in relapsing-remitting forms) or over time (progressively). Symptoms may completely resolve in between attacks. In addition, the likelihood of having permanent neurological damage is high especially as the disease progresses.
Teriflunomide is a pyrimidine synthesis inhibitor. Teriflunomide acts via the mechanism of a dihydroorotate dehydrogenase inhibitor and it is an orally available immunomodulator used in the treatment of relapsing-remitting multiple sclerosis. Chemical name of teriflunomide is (Z)- 2-cyano-3-hydroxy-N-[4-(trifluoromethyl)phenyl]but-2enamide and its chemical structure is shown in Formula I.
Formula I. Teriflunomide
Teriflunomide inhibits rapidly dividing cells including activated T cells that are believed to drive the disease process in MS and it may decrease the risk of infection thanks to its more limited effects on the immune system compared to chemotherapeutic agents.
The document EP0527736B1 is the first molecule patent that describes teriflunomide in the prior art. It mentions the use of teriflunomide in the prophylaxis and/or treatment of rheumatic diseases and the possibility to administer the pharmaceuticals of the invention orally, topically, rectally and parenterally, if required.
The document EP1381356 in another state of the art mentions oral administration of teriflunomide and describes the use thereof in producing a drug for the treatment of multiple sclerosis. Document no. W02013062442 describes a composition comprising teriflunomide and colloidal silicone dioxide in an amount between 0.8-1.2% by weight.
The mentioned compositions show a slightly less degradation of teriflunomide but cannot shed a light on stability and solubility problems. According to the prior art as provided above, there is still a need for stable and highly soluble teriflunomide formulations.
Objectives and Brief Description of the Invention
The main object of the present invention is to obtain teriflunomide containing pharmaceutical compositions that eliminate the above-mentioned problems and provide additional advantages to the relevant prior art.
Another object of the present invention is to obtain solid pharmaceutical compositions of teriflunomide with high stability and solubility profile.
Another object of the present invention is to obtain more stable formulations of humidity- sensitive teriflunomide without using glidants.
Another object of the present invention is to provide a solid oral pharmaceutical composition comprising at least one film coating that protects the composition against humidity in order to maintain stability.

Colloidal silicon dioxide is a fumed silica that is prepared with the hydrolysis of a silica compound. Its particle size is around 15nm and it is an amorphous powder that is odorless, tasteless and water-insoluble. Colloidal silicon dioxide can cause stability problems in pharmaceutical compositions depending on its amount therein due to its hygroscopic structure that enables absorbing a high amount of water. Colloidal silicon dioxide acts both as a lubricant and glidant in solid oral pharmaceutical compositions. Although it is frequently used in formulations due to its fluidity, the fact that it increases the rate of becoming unstable by promoting degradation and has highly humectant properties reveals the reasons for not preferring colloidal silicon dioxide especially in compositions that are sensitive to humidity.
