Baricitinib Delivers High Rates of Hair Regrowth in Adolescents With Severe Alopecia—Largest Pediatric Study Shows Promising One-Year Data
Majority of Adolescents Achieve Significant Regrowth After One Year
Adolescents living with severe alopecia areata, a condition marked by dramatic scalp hair loss, are seeing real progress. New results from the phase 3 BRAVE-AA-PEDS trial reveal that once-daily baricitinib—discovered by Incyte and licensed to Eli Lilly—delivered successful scalp hair regrowth for the majority of young patients at one year. Specifically, 71% of those with severe disease who received the higher 4 mg dose experienced substantial improvement. This is the largest clinical trial to date focused on children and teens with this condition, a group that has often been left out of research.
Near-Complete Regrowth Rates Impress: A Closer Look at the Data
Before treatment began, study participants faced steep odds, with an average of 89% scalp hair loss and many missing eyebrows and eyelashes as well. But the numbers after one year on baricitinib are hard to ignore. Here’s how adolescent patients responded at 52 weeks:
| Treatment Group | Successful Hair Regrowth (=80% scalp coverage) |
Near-Complete Regrowth (=90% scalp coverage) |
Eyebrow Regrowth | Eyelash Regrowth |
|---|---|---|---|---|
| Baricitinib 4 mg | 54.1% | 41.2% | 64.8% | 63.3% |
| Baricitinib 2 mg | 31.0% | 26.2% | 27.8% | 34.0% |
The data is even stronger for patients who started baricitinib less than two years after their diagnosis: 80% of these early-treated teens on 4 mg reached successful hair regrowth.
Durability and Safety Profile Align With Adult Outcomes
Among adults who maintained their response for one year on baricitinib, the vast majority continued to see regrowth for up to four years—demonstrating long-term effectiveness. The safety profile in adolescents mirrored what has been seen in adults, with no new concerns. Common issues included mild side effects like acne and upper respiratory infections, but serious risks such as major cardiovascular events or opportunistic infections were not observed over one year of monitoring.
Potential Impact: Expanding Access to Effective Treatment for Underrepresented Populations
The study is notable not just for its positive outcomes, but for targeting a population that has had limited options and representation in clinical research. Given these results, Lilly intends to submit the data to global regulators for a potential label update for baricitinib (Olumiant). The trial is also expanding to enroll younger children ages 6 to under 12 years, aiming to fill further treatment gaps.
Key Takeaways for Patients, Physicians, and Investors
- Baricitinib 4 mg enabled over 70% of adolescents with severe disease to achieve substantial regrowth after one year.
- Those who began treatment within two years of diagnosis saw even higher success rates.
- Safety findings are in line with previous baricitinib studies, reinforcing its suitability for younger populations.
- Lilly and Incyte’s commitment to pediatric dermatology research may help redefine the standard of care for alopecia areata in children and adolescents.
While baricitinib is already approved in adults, these new results position it as a potential breakthrough for younger patients. As regulatory submissions progress and the data matures, those interested in innovation for underserved medical populations may want to follow upcoming updates from Incyte and Lilly closely.
