Summary
- Background
Autoimmune polyendocrinopathy candidiasis ectodermal dystrophy (APECED) is a problem of the immune system. In people with APECED, the immune system makes a mistake and attacks the body. Some people with APECED have a type of hair loss called alopecia areata (AA). No drugs are approved to treat AA.
- Objective
To see if a study drug (ruxolitinib) can help hair regrowth in people with APECED-associated AA and if it can improve other symptoms caused by the immune system s attack to the body.
- Eligibility
People aged 12 to 65 years with APECED and severe AA.
- Design
Participants will be in this study for up to 10 months. They will have 5 in-person visits and 6 televisits, each about 4 weeks apart. One in-person visit may be up to a 10-day stay in the hospital.
The first in-person visit will include screening. Participants will have a physical exam. They will have blood tests. Photographs may be taken of their skin. They will answer questions about their quality of life.
Participants will begin taking the study drug during their hospital stay. They will take the pills by mouth twice a day for 8 months. Researchers may take tissue samples from participants scalp, gums, and lower lip. Participants may provide samples of urine, stool, nail clippings, and saliva. They may have an eye exam and an ultrasound exam of their abdomen.
Some tests may be repeated in subsequent in-person visits.
In telehealth visits, participants will answer questions about how they are feeling. They will describe and send photos of hair regrowth. They will be asked to have blood drawn and the results sent to the researchers.
Description
Study Description:
This is a phase 2 open-label study to evaluate the efficacy and safety of the Janus-associated kinase (JAK) inhibitor, ruxolitinib, in severe APECED-associated alopecia areata (AA). Following an 8-wee observation period to assess baseline disease state, qualifying participants may be admitted for up to 10 days for an inpatient visit to start receiving twice daily dosing of oral ruxolitinib. The dose will be increased at weeks 8 and 16, but may be maintained or reduced if the participant experiences certain adverse events (AEs). The total duration of the ruxolitinib regimen is 8 months. At in-person study visits, participants will be monitored for AEs/reactions and will complete patient-reported outcome (PRO) metrics to track their symptoms and general wellbeing. Participants will also have televisits during the months when there is no in-person visit, for AE assessment and local blood draws for safety labs.
Family members or household contacts of participants will also be enrolled to complete a quality-of-life survey, for comparison with a corresponding patient survey.
Primary Objective:
To evaluate the efficacy of ruxolitinib on hair regrowth in participants with APECED-associated AA.
Secondary Objectives:
- To evaluate the safety of ruxolitinib in patients with APECED-associated AA.
- To assess additional measures of efficacy related to hair regrowth in response to ruxolitinib treatment.
- To investigate the effect of ruxolitinib on PROs related to hair regrowth.
- To evaluate the effect of ruxolitinib on histologic and immunologic features of the skin.
Exploratory Objectives:
- To investigate the effect of ruxolitinib on improving clinical symptoms and associated laboratory, histologic, and immunologic abnormalities in affected organs and tissues beyond the skin.
- To investigate the effect of ruxolitinib on PROs of affected organs and tissues beyond the skin.
- To investigate the effect of ruxolitinib on prevention of development of new APECED associated complications during the 32-week treatment period.
- To examine the effects of ruxolitinib on ameliorating immunologic readouts of excessive interferon (IFN)- >=/JAK/STAT signaling in peripheral blood and affected organs and tissues beyond the skin.
- To determine whether ruxolitinib treatment affects the composition of microbial communities at the mucocutaneous barriers.
