6 . The method of claim 1 , wherein said JAK inhibitor is (1r,3r)-3-(cyanomethyl)-3-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrazin-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile, or a pharmaceutically acceptable salt thereof.
7 . The method of claim 1 , wherein said JAK inhibitor is (1s,3s)-3-(cyanomethyl)-3-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrazin-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile, or a pharmaceutically acceptable salt thereof.
8 . The method of claim 1 , wherein the treatment reduces inflammatory nodules, abscess and draining fistulas as measured by the subject's hidradenitis suppurativa clinical response (HiSCR) score.
9 . The method of claim 1 , wherein the treatment reduces the median size of the subject's hidradenitis suppurativa lesions.
10 . The method of claim 1 , wherein the treatment reduces the subject's pain associated with the subject's hidradenitis suppurativa lesions.
11 . The method of claim 1 , wherein the treatment increases the subject's time to develop new hidradenitis suppurativa lesions.
12 . The method of claim 1 , comprising the step of administering to the subject in need thereof [(1S)-2,2-difluorocyclo-propyl][(1R,5S)-3-{2-[(1-methyl-1H-pyrazol-4-yl)amino]pyrimidin-4-yl}-3,8-diazabicyclo[3.2.1]oct-8-yl]methanone, or, a pharmaceutically acceptable salt thereof in an amount effective to treat a symptom of hidradenitis suppurativa in the subject.
13 . The method of claim 12 , wherein said effective amount is about 0.01 to about 100 mg/kg of body weight/day, in a single dose or as divided doses administered two, three or four times per day.
14 . A method for treating hidradenitis suppurativa in a human subject having lesions associated with hidradenitis suppurativa, the method comprising the step of administering to the subject in need thereof N-{cis-3-[methyl(7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino]cyclobutyl}-propane-1-sulfonamide, or a pharmaceutically acceptable salt thereof, in an amount effective to treat a symptom of hidradenitis suppurativa in the subject.
15 . The method of claim 14 , wherein said effective amount is about 0.01 to about 100 mg/kg of body weight/day, in a single dose or as divided doses administered two, three or four times per day.
16 . A method for treating hidradenitis suppurativa in a subject having lesions associated with hidradenitis suppurativa, the method comprising the step of administering to the subject in need thereof a JAK inhibitor selected from the group consisting of JAK1, Tyk2/JAK1, and Tyk2, wherein the treatment effectuates at least one of (i) a reduction of inflammatory nodules, abscess and draining fistulas as measured by the subject's hidradenitis suppurativa clinical response (HiSCR) score, (ii) a reduction of the median size of the subject's hidradenitis suppurativa lesions, (iii) a reduction of the subject's pain associated with the subject's hidradenitis suppurativa lesions, (iv) and/or an increase of the subject's time to develop new hidradenitis suppurativa lesions.
17 . The method of claim 16 , wherein the JAK inhibitor is selected from the group consisting of [(1S)-2,2-difluorocyclo-propyl][(1R,5S)-3-{2-[(1-methyl-1H-pyrazol-4-yl)amino]pyrimidin-4-yl}-3,8-diazabicyclo[3.2.1]oct-8-yl]methanone, [(1R)-2,2-difluorocyclo-propyl][(1R,5S)-3-{2-[(1-methyl-1H-pyrazol-4-yl)amino]pyrimidin-4-yl}-3,8-diazabicyclo[3.2.1]oct-8-yl]methanone, N-{cis-3-[methyl(7H-pyrrolo[2,3-d]pyrimidin-4-yl)amino]cyclobutyl}-propane-1-sulfonamide, (1r,3r)-3-(cyanomethyl)-3-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrazin-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile, (1s,3s)-3-(cyanomethyl)-3-(4-(6-(1-methyl-1H-pyrazol-4-yl)pyrazolo[1,5-a]pyrazin-4-yl)-1H-pyrazol-1-yl)cyclobutane-1-carbonitrile, or, a pharmaceutically acceptable salt thereof.
