The 11 pediatric patients, ages 8-18 years, all with a diagnosis of AA, were treated with tofacitinib. Eight patients, or nearly 73%, experienced hair regrowth, while the other three (27.3%) did not, as the investigators reported in the retrospective chart review.
“A success rate of 73% is very good,” said lead author Cory A. Dunnick, MD, professor of dermatology and director of clinical trials at the University of Colorado at Denver, Aurora. No serious adverse events occurred, and adverse events of any kind were limited, the researchers found.
“It is important to get information into the literature about potential treatments for severe alopecia areata because there is no [Food and Drug Administration]–approved therapy at the present time,” Dr. Dunnick told this news organization. Patients’ insurance plans often deny non–FDA-approved therapies unless there are data to support their use.
The researchers found no correlation between the dose, duration of treatment, or the presence of comorbidities and clinical response.
Oral tofacitinib has been shown to be effective and well tolerated for AA in adults, the researchers said. They referred to recent studies that have used JAK inhibitors, including tofacitinib, “in an effort to inhibit T-cell activation and halt disease progression in adult and pediatric patients” with AA.
Study details
Of the 11 patients evaluated, 6 had alopecia universalis, 1 had alopecia totalis, and 4 had patchy AA. Concomitant medical conditions known to be associated with AA affected four patients. These included atopic dermatitis, autoimmune hypothyroidism, and asthma. One patient reported having two brothers with AA.
The median disease duration was 6 years. “In my experience, JAK inhibitors are less effective for patients with longstanding – more than 10 years – alopecia totalis or alopecia universalis,” Dr. Dunnick said.
Previously, patients had been given methotrexate, oral prednisone, intralesional triamcinolone, topical corticosteroids, and topical diphenylcyclopropenone. During treatment with tofacitinib, 5 of the 11 patients also received topical steroid treatment.
The study was a retrospective chart review, so dosing was not standardized, the researchers said. Most took 5-10 mg twice daily. Median treatment time was 32 months, with a range of 5-39 months.
Patients with a complete or near complete clinical response were categorized as responders; subjectively, these were the patients who had persistent hair regrowth over more than 50% of affected areas. Five patients had complete regrowth of hair on the scalp, eyebrows, and body during treatment. Others had incomplete responses. For instance, one patient had improved growth of eyelashes and eyebrows but not on the scalp. Once the medication was increased to 15 mg daily, the patient had complete regrowth of body hair, eyelashes, and eyebrows but slow regrowth on the scalp after 1 year of treatment.
“Patients are very happy with regrowth of their hair,” Dr. Dunnick said, noting that severe AA affects self-esteem and quality of life.
Other research
In a retrospective study that looked at the effects of oral tofacitinib given to 14 preadolescent patients with AA, 9 experienced “clinically significant improvement” in their Severity of Alopecia Tool score. Three had complete remission, and seven (63.6%) had more than a 50% improvement in the score.
