yes I've heard other JAK's for Alopecia but I don't know where any of the programs stand.
Found this fairly recent article talking about JAKs (ruxolitinib/tofacitinib) in trials for alopecia: http://www.medscape.com/viewarticle/869388 . Early results seem promising. Doesn't appear to me that INCY and PFE are directly involved in these studies so perhaps ACRS is one of the few (only?) companies that is directly involved in pursuing JAKs for alopecia for now.
