METHODS FOR TREATING MULTIPLE SCLEROSIS
The disclosure relates to methods of preserving myelination of axons in a human subject having a demyelinating disease by administration of an effective amount of a monoselective S1P receptor modulator, such as ponesimod.
1 . A method of preserving myelination of axons in a human subject having a demyelinating disease, comprising administering to the subject in need thereof an effective amount of a monoselective S1P receptor modulator.
2 . The method of claim 1 , wherein the monoselective S1P receptor modulator is an S1P1 monoselective receptor modulator.
3 . The method of claim 1 , wherein the S1P1 monoselective receptor modulator is ponesimod.
4 . The method of claim 1 , wherein the demyelinating disease is multiple sclerosis, idiopathic inflammatory demyelinating disease, transverse myelitis, Devic's disease, progressive multifocal leukoencephalopathy, optic neuritis, leukodystrophy, Guillain-Barre syndrome, chronic inflammatory demyelinating polyneuropathy, autoimmune peripheral neuropathy, Charcot-Marie-Tooth disease, acute disseminated encephalomyelitis, adrenoleukodystrophy, adrenomyeloneuropathy, Leber's hereditary optic neuropathy, or HTLV-associated myelopathy.
5 . The method of claim 4 , wherein the demyelinating disease is multiple sclerosis.
6 . The method of claim 5 , wherein the multiple sclerosis is relapsing multiple sclerosis.
7 . The method of claim 6 , wherein the relapsing multiple sclerosis comprises relapsing-remitting disease, clinically isolated syndrome, or active secondary progressive disease.
8 . The method of claim 7 , wherein the relapsing multiple sclerosis comprises active secondary progressive disease.
9 . The method of claim 1 , wherein the human subject is treatment naïve.
10 . The method of claim 1 , wherein the human subject is at an early stage of disease progression and/or has experienced limited demyelination of axons.
11 . The method of claim 1 , wherein about 20 mg of ponesimod is administered orally once daily.
12 . The method of claim 1 , wherein the method comprises an up-titration step at initiation of the method or upon re-initiation of the method after a discontinuation, comprising administering orally once daily 2 mg of ponesimod on days 1 and 2; 3 mg of ponesimod on days 3 and 4; 4 mg of ponesimod on days 5 and 6; 5 mg of ponesimod on day 7; 6 mg of ponesimod on day 8; 7 mg of ponesimod on day 9; 8 mg of ponesimod on day 10; and 9 mg of ponesimod on day 11; 10 mg of ponesimod on days 12, 13, and 14, followed by the administering of the 20 mg of ponesimod once daily thereafter.
13 . The method of claim 1 , wherein the monoselective S1P receptor modulator is administered in the absence of a non-selective S1P receptor modulator or another monoselective S1P receptor modulator.
14 . The method of claim 13 , wherein the monoselective S1P receptor modulator is administered in the absence of a non-selective S1P receptor modulator.
15 . The method of claim 13 , wherein the monoselective S1P receptor modulator is administered in the absence of another monoselective S1P receptor modulator.
16 . The method of claim 1 , wherein the monoselective S1P receptor modulator is administered as a monotherapy.
17 . A pharmaceutical product comprising ponesimod, wherein the pharmaceutical product is packaged and the package includes instructions for administering ponesimod to a human subject having a demyelinating disease in a regimen that is effective in preserving myelination of axons.
