After one year of treatment:
- 54.1% of adolescents receiving baricitinib 4 mg and 31% on the 2 mg dose achieved 80% or greater scalp hair coverage (SALT ≤20).¹ Additionally, 41.2% of those taking 4 mg and 26.2% taking 2 mg achieved near-complete scalp regrowth (SALT ≤10).
- Improvements extended beyond scalp hair. Eyebrow regrowth was observed in 64.8% of patients receiving 4 mg compared to 27.8% with 2 mg, while 63.3% and 34% of the same groups achieved eyelash regrowth, respectively.
- A post-hoc analysis revealed even greater responses among adolescents who had been diagnosed less than two years prior to treatment initiation—80% on the higher dose achieved successful regrowth at one year.
- The safety profile was consistent with prior adult and adolescent data, with no new safety signals identified.
The most common adverse events were acne, upper respiratory tract infection, and influenza.
Baricitinib was the first systemic therapy approved in the United States for adults with severe AA in 2022. Lilly plans to submit the new adolescent data to global regulators for a potential label expansion and will soon begin enrolling younger children (ages 6 to under 12) into the next BRAVE-AA-PEDS cohort.
“These promising results for adolescents reinforce what we see in clinical practice with adults, which is that starting treatment with baricitinib early can lead to higher rates of scalp hair regrowth, including near-complete regrowth for many patients,” said Brittany Craiglow, MD, of Yale School of Medicine. "Systemic treatments for adolescents shouldn't be the last resort, but part of the treatment conversation among doctors, caregivers, and patients from the beginning."
Previous 36-week data for baricitinib
At the 36-week mark, 42% of adolescents receiving the 4 mg dose of baricitinib achieved a SALT score of 20 or less, compared to just 2% in the placebo group. The 2 mg dose also showed effectiveness, with 21% of patients reaching the primary endpoint. Additionally, the higher dose led to 60% of patients achieving at least a 50% improvement in SALT scores, while the lower dose reached 37%. In contrast, only 5% of those on placebo showed similar improvement.2
Eyebrow and eyelash regrowth were also notably higher in the baricitinib groups. By week 36, 43% of patients on the 4 mg dose experienced significant eyebrow regrowth, compared to 14% in the placebo group. Eyelash regrowth followed a similar pattern, with 50% of patients on the higher dose showing improvement versus none in the placebo group.
