Compositions Comprising Sphingosine 1 Phosphate (S1P) Receptor Modulators

Abstract

The present invention relates to stable compositions comprising a sphingosine 1 phosphate (S1P) receptor modulator, suitable for use as a dosage form. The S1P receptor modulators are typically sphingosine analogues, such as 2-substituted 2-amino-propane-1,3-diol or 2-amino-propanol derivatives, e.g. a compound comprising a group of formula Y.
