Use of sGC stimulators, sGC activators, alone and combinations with PDE5 inhibitors for the treatment of systemic sclerosis (SSc)
View Patent ↗The use of sGC stimulators, sGC activators alone, or in combination with PDE5 inhibitors for the prevention and treatment of fibrotic diseases, such as systemic sclerosis, scleroderma, and the concomitant fibrosis of internal organs.
1. A method for reducing collagen production in dermal fibroblasts, reducing myofibroblast differentiation and/or for triggering redifferentiation of myofibroblast in a patient suffering from a fibrotic disease selected from the group consisting of systemic sclerosis (SSc), diffuse systemic sclerosis (dSSc), limited systemic sclerosis (lSSc), overlap type of systemic sclerosis, undifferentiated type of systemic sclerosis, systemic sclerosis sine scleroderma, skin fibrosis, nephrogenic fibrosing dermopathy (NFD), nephrogenic systemic fibrosis (NSF), systemic sclerosis (SSc) concomitant fibrosis of internal organs, and keloid formation, comprising administering an effective amount of a compound according to one of formulae (3), (6) or (27)
to the patient in need thereof; wherein reduction of collagen production in dermal fibroblasts, reduction of myofibroblast differentiation and/or triggering redifferentiation of myofibroblast occurs without vasodilation.
2. The method of claim 1 , comprising administering the compound of one of formulae (3), (6) or (27) in combination with at least one PDE5 inhibitor selected from the group consisting of: tadalafil ((6R,12aR)-2,3,6,7,12,12a-hexahydro-2-methyl-6-(3,4-methylene-dioxyphenyl) pyrazino(1′,2′:1,6) pyrido(3,4-b)indole-1,4-dione), vardenafil (2-(2-ethoxy-5-(4-ethylpiperazin-1-yl-1-sulfonyl)phenyl)-5-methyl-7-propyl-3H-imidazo (5,1-f) (1,2,4)triazin-4-one), sildenafil (3-[2-ethoxy-5-(4-methylpiperazin-1-yl)sulfonyl-phenyl]-7-methyl-9-propyl-2,4,7,8-tetrazabicyclo [4.3.0]nona-3,8,10-trien-5-one), udenafil (5-[2-propyloxy-5-(1-methyl-2-pyrrolidinylethylamidosulfonyl)phenyl]-methyl-3-propyl-1,6-dihydro-7H-pyrazolo(4,3-d)pyrimidine-7-one), dasantafil (7-(3-bromo-4-methoxybenzyl)-1-ethyl-8-[[(1,2)-2-hydroxycyclopentyl]amino]-3-(2-hydroxyethyl)-3,7-dihydro-1-purine-2,6-dione), avanafil (4-{[(3-chloro-4-methoxyphenyl)methyl]amino}-2-[(2S)-2-(hydroxymethyl)pyrrolidin-1-yl]-N-(pyrimidin-2-ylmethyl)pyrimidine-5-carboxamide), mirodenafil, lodenafil, LAS 34179 (triazolo[1,2-]xanthine,6-methyl-4-propyl-2-[2-propoxy-5-(4-methylpiperazino)sulfonyl]phenyl) or a salt, hydrate or hydrate of a salt thereof.
3. The method of claim 2 , wherein the PDE5 inhibitor is sildenafil or vardenafil.
4. The method of claim 1 , wherein the fibrotic disease is systemic sclerosis (SSc) concomitant fibrosis of internal organs.
5. The method of claim 1 , wherein the fibrotic disease is diffuse systemic sclerosis (dSSc).
6. A method for reducing collagen production in dermal fibroblasts, reducing myofibroblast differentiation and for triggering redifferentiation of myofibroblast in a patient suffering from a fibrotic disease selected from the group consisting of systemic sclerosis (SSc), diffuse systemic sclerosis (dSSc), limited systemic sclerosis (lSSc), overlap type of systemic sclerosis, undifferentiated type of systemic sclerosis, systemic sclerosis sine scleroderma, skin fibrosis, nephrogenic fibrosing dermopathy (NFD), nephrogenic systemic fibrosis (NSF), keloid formation, and systemic sclerosis (SSc) concomitant fibrosis of internal organs, comprising administering an effective amount of a compound having the formula (3)
to the patient in need thereof; wherein reduction of collagen production in dermal fibroblasts, reduction of myofibroblast differentiation and/or triggering redifferentiation of myofibroblast occurs without vasodilation.
7. The method of claim 6 , wherein the fibrotic disease is systemic sclerosis (SSc) concomitant fibrosis of internal organs.
