Abstract

The present application relates to a dosage regimen of an S1P receptor modulator or agonist in the course of the treatment of patients suffering from an inflammatory or autoimmune disease or disorder, for example multiple sclerosis (MS).

1 . A method for treating relapsing remitting multiple sclerosis in a patient in need thereof, the method comprising:
 (a) identifying a patient suffering from relapsing remitting multiple sclerosis at risk of contracting infection caused by varicella zoster virus by testing said patient for a history of infection caused by varicella zoster virus,   (b) vaccinating the patient at risk of contracting infection caused by varicella zoster virus, and   (c) administering orally Siponimod or a pharmaceutically acceptable salt thereof to said patient at a daily dosage of 2 mg,   thereby limiting the risk of infection caused by varicella zoster virus,   wherein the relapsing remitting multiple sclerosis is treated by the administration of Siponimod.   
     
     
         2 . The method according to  claim 1 , wherein treating comprises reducing the frequency of clinical exacerbations. 
     
     
         3 . The method according to  claim 1 , wherein Siponimod is administered as a hydrochloride salt. 
     
     
         4 . The method according to  claim 1 , wherein the infection is chickenpox. 
     
     
         5 . A method for treating multiple sclerosis in a patient in need thereof, the method comprising:
 (a) identifying a patient suffering from multiple sclerosis at risk of contracting infection caused by varicella zoster virus by testing said patient for a history of infection caused by varicella zoster virus,   (b) vaccinating the patient at risk of contracting infection caused by varicella zoster virus, and   (c) administering orally a therapeutically effective amount of Siponimod or a pharmaceutically acceptable salt thereof to said patient,   thereby limiting the risk of infection caused by varicella zoster virus,   wherein the multiple sclerosis is treated by the administration of Siponimod.   
     
     
         6 . The method of  claim 5 , wherein the multiple sclerosis is primary progressive multiple sclerosis. 
     
     
         7 . The method of  claim 5 , wherein the Siponimod is administered in a dosage of 0.25 mg twice per day. 
     
     
         8 . The method of  claim 5 , wherein the Siponimod is administered in a dosage of 2 mg per day.
