Long-Term Safety and Effectiveness of Sonelokimab for Hidradenitis Suppurativa
This study offers long-term treatment with an investigational biologic, sonelokimab, for people with moderate to severe hidradenitis suppurativa who finished an earlier sonelokimab study. The goal is to see if sonelokimab remains safe and effective over time.
Northridge, CaliforniaAges 12 years+ - NCT07228390RecruitingPhase 2
Testing ritlecitinib for hidradenitis suppurativa in adults
This study tests an oral medicine called ritlecitinib for moderate to severe hidradenitis suppurativa (HS) in adults who haven't responded well to antibiotics. The goal is to see if it can reduce painful red lumps and improve quality of life.
Fountain Valley, CaliforniaAges 18–75 - NCT04115566Recruiting
HS patient registry and sample storage study
This study enrolls people with hidradenitis suppurativa (HS) to better understand the condition over time and store optional health information and samples. Being in the registry may help researchers learn about patterns in HS and support future research.
San Francisco, CaliforniaAges 10 years+ - NCT05889182RecruitingPhase 3
Testing an oral medicine for moderate to severe hidradenitis
This Phase 3 study tests upadacitinib taken by mouth to reduce hidradenitis suppurativa (HS) symptoms and disease activity, and to track side effects. It is for people who have already tried anti-TNF treatments and still had inadequate response or couldn’t tolerate them.
Encino, CaliforniaAges 12 years+ - NCT06524635RecruitingPhase 2
Study of lutikizumab for hidradenitis suppurativa or eczema
This study tests an investigational medicine called lutikizumab, given as shots under the skin, for people with moderate-to-severe hidradenitis suppurativa (HS) or atopic dermatitis (eczema). It looks at how the medicine affects skin changes and may help if other treatments haven’t worked.
Sacramento, CaliforniaAges 18–75 - NCT06855498RecruitingPhase 3
Rollover study for patients who took povorcitinib before
This study is for people who have already taken the study drug povorcitinib in a previous trial and found it helpful. It lets you continue receiving the treatment and allows doctors to keep tracking its long-term safety and effects.
Fountain Valley, CaliforniaAges 18 years+ - NCT06888193RecruitingPhase 1
Bimekizumab in breast milk of mothers being treated

Santa Monica, CaliforniaAges 18 years+ - NCT05243966Recruiting
Registry for soft tissue repair using a special matrix
This study is a registry that collects information from people who had soft tissue repair using a specific matrix and/or morcell material. It may help researchers understand how this approach performs in real-world care and patient outcomes over time.
Los Angeles, CaliforniaAges 18 years+ - NCT07123038Recruiting
Long-term safety study for gene-modified Treg therapy recipients
This study follows people who previously received a gene-modified Treg (regulatory T cell) therapy from Sonoma Biotherapeutics. It checks for long-term safety and does not involve any new treatment.

What taking part in a hidradenitis suppurativa study involves
A screening visit first
Before anything else, the study team checks whether you fit — usually a visit with some tests. You can stop at any point, and screening is typically free.
Care at a nearby site
Study visits happen at a clinic or hospital taking part. Many studies cover the cost of the study treatment and related visits, and some reimburse travel.
You stay in control
Taking part is voluntary and you can leave a study at any time, for any reason, without affecting your regular care.
The team decides eligibility
Our fit check is a helpful first read, not a decision. The study team makes the final call after reviewing your health history.
