Definitions

  • the invention relates to pharmaceutical compositions comprising the compound fingolimod as the active pharmaceutical ingredient.

  • SIP sphingosine- 1 -phosphate
  • fingolimod became the first oral disease-modifying drug approved for treating multiple sclerosis.
  • Fingolimod itself is a prodrug and gets phosphorylated to the active metabolite (S)- fingolimod phosphate ester by sphingosine kinases in liver cells.
  • Fingolimod may form stable acid addition salts, of which fingolimod hydrochloride is the most common one.
  • the approved product sold e.g., under the trade name Gilenya ®
  • Gilenya ® is a hard-shell capsule filled by a powder comprising 0.56 mg of fingolimod hydrochloride (corresponding to 0.5 mg of fingolimod free base) per capsule.
  • the powder further comprises mannitol as a filler and a small amount of magnesium stearate as a lubricant.
  • WO 2004/089341 discloses a solid pharmaceutical composition suitable for oral administration comprising various SIP receptor agonists and a sugar alcohol.
  • the sugar alcohol may act as a diluent, carrier, filler or bulking agent and may suitably be mannitol, maltitol, inositol, xylitol and/or lactitol. It is taught that these compositions do not suffer from the disadvantages of liquid formulations for injection or oral use and have good

  • the composition may be in the form of a powder, granule, pellet or tablet.
  • fingolimod hydrochloride is mixed with mannitol and a lubricant and, optionally with a binder such as HPC or HPMC, milled and/or granulated.
  • composition of the marketed product Gilenya ® falls within the scope of the compositions that are disclosed and claimed in WO 2004/089341.
  • WO 2008/037421 provides formulations comprising a SIP receptor modulator and adapted for oral administration in solid form, which can be easily swallowed, e.g. by children or elderly patients.
  • the invention provides dosage forms, which disintegrate rapidly in the mouth and do not depend on the presence of a taste masking agent or on the presence of water for washing down the dosage form. It also provides compositions comprising an SIP receptor modulator, wherein the composition is coated by a coating comprising one or more polymer resins and one or more metal oxides. In further, it provides a composition comprising an SIP receptor modulator and microcrystalline cellulose in the absence of a sugar alcohol.
  • WO 2009/048993 teaches that various SIP receptor modulators comprising an aminopropane-l,3-diol group (such as, e.g., fingolimod) are not easy to formulate in a solid oral formulation; only a limited number of excipients are potentially feasible with such amino diols. In particular, reducing sugars are not considered suitable due to the danger of a Maillard reaction with the amino-group.
  • aminopropane-l,3-diol group such as, e.g., fingolimod
  • the only suitable fillers providing stable blends with the aminopropane-l-3-diol based SIP receptor modulator are lactose, lactose monohydrate, maize starch, mannitol, xylitol, sorbitol, sucrose, microcrystalline cellulose, dibasic calcium phosphate, maltodextrin and gelatin. This selection was supported by stability testing of various blends comprising fingolimod and the excipient for 1 month at 50°C. In addition, several binders, disintegrants, lubricants, flow regulators, matrix formers, plasticizers, flavouring agents, and sweeteners were marked as suitable for making solid oral formulations.
  • SIP receptor modulators comprising an aminopropane-l,3-diol group are not easily formulated into a stable solid oral formulation. Hence, this is because of the reactivity of the aminopropane-l,3-diol group. Only a limited number of suitable pharmaceutical excipients, particularly fillers, have been accordingly found. Thus, it will be beneficial to provide an alternative and/or improved composition for oral administration of fingolimod, which is stable and has good handling properties in making pharmaceutical dosage forms for oral administration.
