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 consisting of orally administering to the human subject an effective amount of a small molecule JAK3 inhibitor, wherein the alopecia areata in the human subject is treated.
2. The method of claim 1 , wherein the small molecule JAK3 inhibitor is selected from Janex 1 (WHI-P131), PF-956980, WHI-P154, tofacitinib (CP690550), VX-509, JAK3 Inhibitor IV (ZM-39923), NSC114792, R348, a pharmaceutically acceptable salt thereof, and a combination thereof.
3. The method of claim 1 , wherein the alopecia areata is selected from patchy alopecia areata, alopecia totalis, and alopecia universalis.
4. The method of claim 1 , wherein the JAK3 inhibitor is administered in a pharmaceutical composition selected from the group consisting of a solution, suspension, capsule, tablet, pill, and troche.
5. The method of claim 1 , wherein administering to the human subject occurs daily.
6. The method of claim 1 , wherein treatment is inducing hair growth.
7. The method of claim 1 , wherein the human subject is an adult.
8. The method of claim 1 , wherein the human subject is a child.
9. The method of claim 7 , wherein the effective amount is about 1 mg/kg body weight of the human subject.
10. The method of claim 7 , wherein the effective amount is selected from 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 and about 950 μg/kg body weight of the human subject.
11. The method of claim 7 , wherein treatment is inducing hair growth.
12. A method of treating severe alopecia areata in a human subject in need thereof, the method consisting of orally administering once daily to the human subject an effective amount of a small molecule JAK3 inhibitor, wherein the alopecia areata in the human subject is treated.
13. The method of claim 12 , wherein the small molecule JAK3 inhibitor is selected from Janex 1 (WHI-P131), PF-956980, WHI-P154, tofacitinib (CP690550), VX-509, JAK3 Inhibitor IV (ZM-39923), NSC114792, R348, a pharmaceutically acceptable salt thereof, and a combination thereof.
14. The method of claim 12 , wherein the severe alopecia areata is selected from alopecia totalis and alopecia universalis.
15. The method of claim 12 , wherein the human subject is an adult.
16. The method of claim 12 , wherein the human subject is a child.
