Dosing regimen for a selective S1P
The present invention relates to a dosing regimen for a selective S1P 1 receptor agonist, whereby the selective S1P 1 receptor agonist is administered to a subject in such a way that during the initial treatment phase the selective S1P 1 receptor agonist is administered at a dose which induces desensitization of the heart wherein said dose is below the target dose, and at a dosing frequency that sustains desensitization of the heart, until no further acute heart rate reduction occurs, followed by dose up-titration to the target dose of the selective S1P 1 receptor agonist.
1. A kit containing different units of medication of a selective S 1 P 1 receptor agonist that is (R)-5-[3-chloro-4-(2,3-dihydroxy-propoxy)-benz[Z]ylidene]-2-([Z]-propylimino)-3-o-tolyl-thiazolidin-4-one (“Compound 1”), or a pharmaceutically acceptable salt thereof, said kit comprising one or more units of a dose strength below the target dose of Compound 1 or a pharmaceutically acceptable salt thereof corresponding to an initial treatment phase, and subsequent units of medication of 5- to 16-fold higher dose strengths compared to the initial dose strength up to the target dose of Compound 1 or a pharmaceutically acceptable salt thereof, and instructions for administering Compound 1 or a pharmaceutically acceptable salt thereof to a human subject in need thereof wherein during the initial treatment phase the one or more units of a dose strength below the target dose are administered to the subject, followed by up-titration of the subsequent units up to the target dose of Compound 1 or a pharmaceutically acceptable salt thereof, wherein the instructions provide for administering the dose strength unit(s) below the target dose at a dosing frequency of once or twice daily and administering the target dose p.o. once daily, wherein the target dose is 20 mg, and wherein the kit does not contain any units of medication of Compound 1 in an amount that exceeds the target dose.
2. The kit according to claim 1 , wherein the dose strength units below the target dose are provided for the initial 2 to 4 days of treatment.
3. A kit containing different units of medication of a selective S 1 P 1 receptor agonist that is (R)-5-[3-chloro-4-(2,3-dihydroxy-propoxy)-benz[Z]ylidene]-2-([Z]-propylimino)-3-o-tolyl-thiazolidin-4-one (“Compound 1”), or a pharmaceutically acceptable salt thereof, said kit comprising one or more units of a dose strength below the target dose of Compound 1 or a pharmaceutically acceptable salt thereof corresponding to an initial treatment phase, and subsequent units of medication of 2- to 5-fold higher dose strengths compared to the initial dose strength up to the target dose of Compound 1 or a pharmaceutically acceptable salt thereof, and instructions for administering Compound 1 or a pharmaceutically acceptable salt thereof to a human subject in need thereof wherein during the initial treatment phase the one or more units of a dose strength below the target dose are administered to the subject, followed by up-titration of the subsequent units up to the target dose of Compound 1 or a pharmaceutically acceptable salt thereof, wherein the instructions provide for administering the dose strength unit(s) below the target dose at a dosing frequency of once or twice daily and administering the target dose p.o. once daily, wherein the target dose is 20 mg, and wherein the kit does not contain any units of medication of Compound 1 in an amount that exceeds the target dose.
4. The kit according to claim 3 , wherein the dose strength units below the target dose are provided for the initial 2 to 4 days of treatment.
