A Study to Evaluate the Safety and Effectiveness of Upadacitinib in Pediatric Participants With Alopecia Areata

2026. szeptember 15. frissítette: AbbVie

A Phase 3 Randomized, Placebo-controlled, Double-blind Study to Evaluate Efficacy and Safety of Upadacitinib in Pediatric Subjects With Severe Alopecia Areata

Alopecia areata (AA) is a disease that happens when the immune system attacks hair follicles and causes hair loss. AA usually affects the scalp and face, but hair loss can happen on any hair-bearing part of the body. Some treatment options are available for adults and adolescents with AA, however there is still high unmet need for systemic treatments (treatment that moves throughout the bloodstream) approved for young patients with AA. Treatments may not work for all patients or may stop working over time. Because of this, researchers are developing new AA treatments, like upadacitinib. Upadacitinib is a type of medicine called a Janus- Kinase (JAK) inhibitor and works with the body to fight the inflammation that can cause AA. In this study, different doses (amounts) of upadacitinib are being compared to treatment with placebo (looks like the study treatment but contains no medicine).

Upadacitinib is an investigational JAK inhibitor being developed for the treatment of severe alopecia areata in pediatric patients. This is a randomized, double-blind, placebo-controlled study. Participants are placed in 3 groups, called treatment arms. Each group receives a different treatment. There is a 1 in 5 chance that participants will be assigned to placebo. Pediatric participants with a diagnosis of severe alopecia areata with SALT score ≥ 50 scalp hair loss will be enrolled. Participants will be at least 6 years old at Screening and less than 18 years old at Baseline. Approximately 300 participants will be enrolled in the study at approximately 120 sites worldwide.

Participants will receive oral doses of upadacitinib or matching placebo daily, or twice daily, for approximately 160 weeks. The study comprises a 35-day Screening Period, a 24-week placebo-controlled double-blinded treatment period (Period A), a 28-week blinded extension treatment period (Period B), a 108-week blinded long-term extension period (Period C), and a 30-day follow-up period.

There may be higher treatment burden for participants in this trial compared to their standard of care. Participants will attend regular visits during the study at a hospital or clinic. The effect of the treatment will be checked by medical assessments, blood tests, checking for side effects and completing questionnaires.

Időkeret
Percentage of Participants with the Achievement of Severity of Alopecia Tool (SALT) Score <= 20, defined as less than or equal to 20% scalp hair loss.
Időkeret: At Week 24
The SALT is a global AA severity score based on the combination of extent and density of scalp hair loss. The score is determined by visually defining the amount of terminal hair loss in each of the 4 views of the scalp (left and right side each accounting for 18% of scalp area, the top for 40%, and the back for 24%) and adding these together with a maximum score of 100%.

Number of Participants with Adverse Events (AEs)
Időkeret: Up to Week 160
An AE is defined as any untoward medical occurrence in a patient or clinical investigation in which a participant is administered a pharmaceutical product which does not necessarily have a causal relationship with this treatment.

The HADS is a self-administered scale which measures anxiety and depression. It contains 14 items and is comprised of anxiety (7 items) and depression (7 items) subscales, which are scored separately and summed to give a total score.

The CDLQI is a 10-item, validated questionnaire used in clinical practice and clinical trials to assess the impact of dermatological disease symptoms and treatment on quality of life. The CDLQI has been validated for use in Participants 4 to 16 years of age. It consists of 10 questions assessing impact of skin diseases on different aspects of quality of life over the prior week. The CDLQI items include symptoms and feelings, daily activities, leisure, school, relationships, sleep, and treatment. Each item is scored on a 4-point scale: 0 = not at all; 1 = only a little; 2 = quite a lot; and 3 = very much. Item scores (0 to 3) are added to provide a total score range of 0 to 30; higher scores indicate greater impairment of quality of life.

It consists of 6 items that measure core aspects of mood, thoughts, and behaviors related to depression, as observed by the caregiver over the past 7 days. Caregivers are asked to rate each item using a 5-point Likert scale ranging from 'Never' to 'Almost Always'. Higher scores reflect greater severity of depressive symptoms.
