How effective really is the drug Ruxolitinib in the treatment of Alopecia Areata?

The drug is from Novartis and acts in the auto immune system. It is supposed to be applied for the treatment of myelofibrosis. Do you know anything about this medication?

Ruxolitinib and Tofacitinib for Alopecia areata - How good are they?

These drugs are known as JAK inhibitors because they inhibit a pathway inside cells known as the JAK pathway. Ruxolitinib (also known as Jakaf/Jakavi) inhibits JAK 1 and 2 and Tofacitinib (also known as Xeljanz) inhibits JAK 1 and JAK 3.

Ruxolitinib can be quite effective, but that does not mean it's the first drug any patient should reach for or ask about. In fact, it's not even the second drug. Given how new it is and the number of potential side effects, other treatments should be tried first. These drugs, in my opinion, are only for more advanced stages of alopecia areata. I never use these medications for a patent with one or two patches of alopecia areata, but I will use these medications for someone with extensive hair loss - who has not responded to conventional treatments. 

 Two new studies published recently in the journal JCI Insight support their benefits of these drugs

1) One new study by Mackay-Wiggans and colleagues reported results of an open label trial of 12 patients with moderate to severe alopecia areata using oral ruxolitinib at a dose of 20 mg twice daily for 3-6 months followed by 3 months off the drug. 9 of 12 patients reported "significant" growth with no serious adverse events.

2) In another study, investigators from Yale and Columbia University reported results of a study of 66 patients with advanced alopecia areata (including totalis and universalis). Patients received tofacitinib 5 mg twice daily for three months. Patients with alopecia totalis and universalis were less responsive than patients with alopecia areata but overall about one-third of patients experienced significant improvement. What was also very important to note was patients relapsed very quickly when the medication was stopped – losing hair within 8.5 weeks of stopping.


Certainly, these JAK inhibitors, including ruxolitinb  continue to show evidence of being helpful for patients with advanced alopecia areata. We have been using tofacitinib for some time now and it's evident now that in advanced alopecia areata it offers the potential to help a lot. The study I mentioned second reminds us that these are not cures and that patients lose hair when the treatment is stopped.

Loss of hair is a natural process when it is between the limits that the body can restore them. When the capacity of the body to restore the hair loss is beaten by the excessive hair loss then we can name this situation something that should be treated. Women started to experience balding even more in the last 2 decades. It is getting more and more common also in women population. However it is also good to know that this problem is also treatable when it is present in women.

To obtain alive hair follicles implanted in higher rates, the latest technique being used is not the only manner, it is also affected by compliance of implantation area that we found a better way to improve as a result of our researches, The Organic Hair Transplantation. By this new and unique Organic Hair Transplantation Technique, before the extraction and implantation processes; we regenerate the implantation area with injection of stem cell enriched fat tissue. Regeneration of cells in target area before FUE transplantation with the support of stromal stem cells results in higher rate of alive thicker hair follicles.

Other treatment options are available for alopecia areata

Ruxolitinib is a monoclonal antibody that is FDA approved used for rheumatoid arthritis. It has been shown in limited studies to regrow hair in rats. A very small subset of patients tested have had initial growth of hair, however it is not FDA approved for alopecia areata, and long term results are unknown. Other treatment options are available for alopecia areata.
