Description

A COMBINATION COMPRISING FINGOLIMOD AND AMANTADINE Field of the invention
The present invention relates to a pharmaceutical combination comprising fingolimod or a pharmaceutically acceptable salt thereof and amantadine or a pharmaceutically acceptable salt thereof for use in the treatment of multiple sclerosis in human, preferably in the prevention or the treatment of fatigue symptom of multiple sclerosis disease.
Background of the invention
Multiple Sclerosis (MS) is a chronic disease of the central nervous system (CNS) resulting in loss of muscle control, balance, and sensation. Autoimmunity, infectious agents, environmental triggers and hereditary factors influential in disease development.
Myelin provides a covering or insulation for nerves, improves the conduction of impulses along the nerves and also is important for maintaining the health of the nerves. In multiple sclerosis, inflammation causes the myelin to disappear. So, the electrical impulses become slower. In addition, the nerves themselves are damaged. Patient suffers from a range of symptoms which affect their health-related quality of life such as pain, fatigue, muscle spasticity and spasm, bladder problems and sleep disturbance.
Fingolimod is a sphingosine-1 -phosphate receptor modulator, which sequesters lymphocytes in lymph nodes, preventing them from contributing to an autoimmune reaction. Fingolimod is used in the treatment of the relapsing form of multiple sclerosis. May also be used in chronic inflammatory demyelinating polyneuropathy.
Fingolimod is marketed by Novartis under the brand name Gilenya® for the treatment of multiple sclerosis. Gilenya® is presented as immediate-release hard gelatin capsules containing 0.56 mg of fingolimod hydrochloride as the active substance corresponding to 0.5 mg of fingolimod.
The chemical name of fingolimod is 2-amino-2-[2-(4-octylphenyl)ethyl]propane-1 ,3-diol. Fingolimod is shown as Formula I.
Figure imgf000002_0001
Formula I
In the prior art, fingolimod derivatives are firstly disclosed in US5604229. The use of fingolimod derivatives as immune depressant and preventive for autoimmune diseases is disclosed in EP0627406 (B1). The use of fingolimod derivatives in the prevention or in the treatment of chronic rejection in a recipient of organ or tissue alio- or xeno-transplant is disclosed in EP0941082 (B1).
There is no known cure for MS until now. Current treatments typically focus on accelerating patient’s recovery from attacks, slowing the progression of the disease and restraining MS symptoms. Fingolimod alone does not provide adequate treatment. In the present invention, the strategy to improve the current state of MS treatment is combining therapies.
Fatigue is a common symptom of people with MS. This is called "MS fatigue" and this is different from fatigue experienced by persons without MS. This also can arise from associated conditions or accumulation of disease burden. Specific causes to consider include sleep disorders, depression, disability status.
Therefore, there is a need in the prior art to develop a formulation comprising fingolimod and an active agent for reducing undesired multiple sclerosis symptoms which can be fatigue as well as an improved side effect profile and increased patient compliance.
Multiple sclerosis is a heterogeneous disease that develops as an interplay between the immune system and environmental stimuli in genetically susceptible individuals. There is increasing evidence that viruses may play a role in MS pathogenesis acting as these environmental triggers. (CNS & Neurological Disorders - Drug Targets, 2012 Aug, Viruses and Multiple Sclerosis, Jussi Oskari Virtanen, Steve Jacobson). Based on this knowledge, the use of fingolimod with an antiviral agent was considered. Example of antiviral agents is amantadine, rimantadine, zanamivir, oseltamivir, peramivir.
Amantadine is an antiviral that is used in the prophylactic or symptomatic treatment of influenza A. It is also used as an antiparkinsonian agent, to treat extrapyramidal reactions, and for postherpetic neuralgia. The chemical name of amantadine is 1-adamantanamine. Its molecular weight is 151.253 with a molecular formula C H N. It has the following structural formula as Formula II.
Figure imgf000004_0001
Formula II
Thus, there is no combination of fingolimod with amantadine in the prior art. In this invention, combining more than one molecule in one dosage form increases the patient’s compliance. However, while this combination increases the patients’ quality of life, combining more than one molecule in one dosage form also reduces undesired multiple sclerosis symptoms and provide effective treatment.
Detailed description of the Invention
The main object of the present invention is to combine fingolimod with amantadine to eliminate multiple sclerosis symptoms and to provide effective treatment.
Another object of the present invention is to obtain a stable combination formulation with a synergistic effect for use in multiple sclerosis.
This invention also provides a pharmaceutical combination comprising effective amount of fingolimod and an effective amount of amantadine, for use in treating a human afflicted with multiple sclerosis. The combination is administered simultaneously, separately or sequentially.
The term“fingolimod” as used herein refers to fingolimod in the form of the free base or in the form of pharmaceutically acceptable salts, crystalline polymorph, solvates, hydrates, esters or mixture thereof.
The term“amantadine” as used herein refers to amantadine in the form of the free base or in the form of pharmaceutically acceptable salts, crystalline polymorph, solvates, hydrates, esters or mixture thereof.
According to one embodiment of the present invention, the pharmaceutical combination comprises fingolimod and amantadine. The combination is used as adjunctive therapy in fatigue for multiple sclerosis treatment. According to another embodiment of the present invention, the combination is for use in the treatment of multiple sclerosis in human.
According to a further embodiment of the present invention, the combination is for use to prevent or treatment fatigue symptom of MS disease.
An embodiment of this present invention is to combine fingolimod with amantadine in a same and stable dosage form with desired dissolution profiles.
