METHODS FOR TREATING HAIR LOSS DISORDERS
The invention provides for methods for treating a hair loss disorder in a subject by administering a Janus Kinase/Signal Transducers and Activators of Transcription inhibitor.
1 . A method of treating alopecia areata in a human subject in need thereof, the method comprising orally administering to the human subject an effective amount of a small molecule JAK1 inhibitor, wherein the alopecia areata in the human subject is treated.
2 . The method of claim 1 , wherein the JAK1 inhibitor is administered in a pharmaceutical composition selected from the group consisting of a solution, suspension, capsule, tablet, pill, and troche.
3 . The method of claim 1 , wherein administering to the human subject occurs once daily.
4 . The method of claim 1 , wherein treatment is inducing hair growth.
5 . The method of claim 1 , wherein the human subject is an adult.
6 . The method of claim 1 , wherein the human subject is a child.
7 . A method of treating severe alopecia areata in a human subject in need thereof, the method comprising orally administering to the human subject an effective amount of a small molecule JAK1 inhibitor, wherein the alopecia areata in the human subject is treated.
8 . The method of claim 7 , wherein the severe alopecia areata is selected from alopecia totalis and alopecia universalis.
9 . The method of claim 7 , wherein an effective amount is selected from about 100 μg/kg body weight of the human subject, about 150 μg/kg body weight of the human subject, about 200 μg/kg body weight of the human subject, about 250 μg/kg body weight of the human subject, about 300 μg/kg body weight of the human subject, about 350 μg/kg body weight of the human subject, about 350 μg/kg body weight of the human subject, about 400 μg/kg body weight of the human subject, about 450 μg/kg body weight of the human subject, about 500 μg/kg body weight of the human subject, about 550 μg/kg body weight of the human subject, about 600 μg/kg body weight of the human subject, about 650 μg/kg body weight of the human subject, about 700 μg/kg body weight of the human subject, about 750 μg/kg body weight of the human subject, about 800 μg/kg body weight of the human subject, about 850 μg/kg body weight of the human subject, about 900 μg/kg body weight of the human subject, about 950 μg/kg body weight of the human subject, and about 1000 μg/kg body weight of the human subject.
10 . The method of claim 7 , wherein administering to the human subject occurs once daily.
11 . The method of claim 7 , wherein treatment is inducing hair growth.
12 . The method of claim 7 , wherein the human subject is an adult.
13 . The method of claim 7 , wherein the human subject is a child.
14 . A method of treating severe alopecia areata in a human subject in need thereof, the method comprising orally administering to the human subject an effective amount of a small molecule JAK1/JAK2 inhibitor, wherein the alopecia areata in the human subject is treated.
15 . The method of claim 14 , wherein the small molecule JAK1/JAK2 inhibitor is selected from AG490, CYT387, SB 1518, LY3009104, TG101348, BMS-91 1543, CEP-701, a pharmaceutically acceptable salt thereof, and a combination thereof.
16 . The method of claim 14 , wherein the severe alopecia areata is selected from alopecia totalis and alopecia universalis.
17 . The method of claim 14 , wherein an effective amount is selected from about 100 μg/kg body weight of the human subject, about 150 μg/kg body weight of the human subject, about 200 μg/kg body weight of the human subject, about 250 μg/kg body weight of the human subject, about 300 μg/kg body weight of the human subject, about 350 μg/kg body weight of the human subject, about 350 μg/kg body weight of the human subject, about 400 μg/kg body weight of the human subject, about 450 μg/kg body weight of the human subject, about 500 μg/kg body weight of the human subject, about 550 μg/kg body weight of the human subject, about 600 μg/kg body weight of the human subject, about 650 μg/kg body weight of the human subject, about 700 μg/kg body weight of the human subject, about 750 μg/kg body weight of the human subject, about 800 μg/kg body weight of the human subject, about 850 μg/kg body weight of the human subject, about 900 μg/kg body weight of the human subject, about 950 μg/kg body weight of the human subject, and about 1000 μg/kg body weight of the human subject.
18 . The method of claim 14 , wherein administering to the human subject occurs once daily.
19 . The method of claim 14 , wherein treatment is inducing hair growth.
20 . The method of claim 14 , wherein the human subject is an adult.
21 . The method of claim 14 , wherein the human subject is a child.
