This is an expanded access program (EAP) for eligible participants. This program is designed to provide access to upadacitinib prior to approval by the local regulatory agency. Availability will depend on territory eligibility. A medical doctor must decide whether the potential benefit outweighs the risk of receiving an investigational therapy based on the individual patient's medical history and program eligibility criteria.

This is an observational study designed to evaluate the safety and clinical outcomes of Myriad™ in soft tissue reconstruction procedures. The study will enroll participants who are undergoing a surgical procedure, where the attending physician will use Myriad™ as part of the surgical intervention.

The purpose of this study is to learn about the safety and effects of the study medicine (called Ritlecitinib) for the possible treatment of hidradenitis suppurativa (HS). HS is a disease causing long lasting painful red skin lumps. This study is seeking participants who: * have moderate or severe HS * have previously received antibiotics for HS that did not help, or could not tolerate antibiotics Participants will be randomly (like a flip of coin) assigned to receive either the study medicine or a placebo (a pill that looks like the study medicine but does not contain any medicine). The study medicine or placebo will be taken by mouth once daily at home. For the first part of the study, participants will receive a loading (starting) dose. For the next part of the study, participants will receive a maintenance (ongoing) dose. Participants will take part in the study for about 24 weeks (about 6 months). There will be about 10 study clinic visits: a screening visit, Day 1, and then every 1, 2, or 4 weeks until week 16. At each visit, participants will report on their health and have tests such as physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. Participants will record when they take the study medicine and their HS symptoms every day in an eDiary on a mobile phone. The experiences of participants receiving the study medicine will be compared to those receiving placebo to help see if the study medicine is safe and effective.

The aim of this study is to evaluate the effectiveness of early treatment with secukinumab in patients with moderate-to-severe hidradenitis suppurativa (HS) and assess its impact on disease progression using data from multiple European data sources. All data will be sourced from existing non-interventional study primary data collection, registries, and hospital cohorts that captured information collected in routine clinical practice, prior to and independent of this study.

This is a multinational, randomized, double-blind, placebo-controlled, Phase 2, dose finding study to evaluate the efficacy and safety of different doses of SAR445399 in adult participants with moderate to severe hidradenitis suppurativa. The purpose of this study is to assess the efficacy and safety of two doses of SAR445399 compared with placebo in adult participants with moderate to severe hidradenitis suppurativa. The study duration (per participant) will be up to 46 weeks with a total of 16 visits. The treatment duration will be 32 weeks which includes 16-week double-blinded initial treatment period and a 16-week treatment-blinded extension period.

The HS-RISE study aims to assess real-world HS treatment outcomes and patterns, safety of secukinumab, and to describe the baseline characteristics of patients diagnosed with moderate-to- severe HS who are prescribed secukinumab in Canadian routine clinical practice.

Chronic inflammatory skin diseases constitute a heterogeneous group of pathologies. They affect the skin but also other organs (joints, lungs, muscles, etc.). Their prognosis and response to treatments is extremely variable. The discovery of prognosis factors will help to precisely guide the treatment regimen and its intensification based on individual markers. The identification of new therapeutic targets is essential to develop new innovative treatments for inflammatory skin diseases. The main objective is to identify new cellular or molecular prognostic factors associated with treatment response at 1 year in inflammatory skin diseases. The secondary objectives are a better understanding of the pathophysiology of chronic inflammatory skin diseases, the identification of new cellular, molecular and microbiological prognostic factors associated with the clinical state after 10 years of evolution and the identification of prognostic markers of drug toxicity.

This study is to investigate the efficacy of siplizumab in the treatment of Hidradenitis Suppurativa.

The main purpose of this study is to assess the efficacy of multiple dosing regimens of LAD191 compared to placebo in participants with moderate-to-severe Hidradenitis Suppurativa (HS) and to access the safety, tolerability, pharmacokinetic and immunogenicity in participants with moderate-to-severe HS.

Hidradenitis suppurativa (HS) is a common and debilitating skin disease that is poorly understood and understudied. As a result, little is known about disease prognosis and few effective treatments exist for this condition. This prospective observational cohort study aims to comprehensively characterize the clinical and biological features of HS. The results of this research will provide a basis for the development of an HS clinical classification system and identification of potential treatments for HS.

The purpose of the study is to collect different samples for molecular characterization of inflammatory skin diseases.

Hidradenitis Suppurativa (HS) is a skin condition that causes deep, painful bumps on the skin. These bumps usually appear in an area where the skin rubs together. They start as small bumps but may become swollen and red over time. If they fill with pus, these lumps are called abscesses; these can also burst. Over time, the area can get scars and tunnels on or under the skin. Recent studies suggest that the condition may start when hair follicles become damaged and blocked. This impacts the skin and may activate the body's germ-fighting (immune) system. This allows bacteria to grow on the skin which worsens the condition and can cause abscesses. The main aims of this study are to learn how safe zasocitinib is, how well it works and how well adults with HS tolerate it compared with a placebo. The participants will receive the study treatment (either zasocitinib or placebo) for up to 4 months (16 weeks). The placebo looks like the zasocitinib capsule but does not have any medicine in it. After the first 4 months, all participants (also those who initially received placebo) will then receive zasocitinib for up to 8 months (36 weeks). During the study, participants will visit their study clinic 12 times.

Regulatory Post-Marketing Surveillance in hidradenitis suppurativa, pediatric plaque psoriasis and JIA treated with Cosentyx®(secukinumab) in Korea

This study will create and extend a source of clinical specimens for the future study of inflammatory skin disorders.

HS is relatively common in the United States with a prevalence of 0.1-1.0%. 1 HS has a dramatic impact on quality of life, significantly more so than other chronic skin diseases, such as psoriasis or atopic dermatitis (AD). HS also has a large economic impact, due to frequent emergency department and inpatient care utilization, and re-hospitalization rates similar to congestive heart failure. Unfortunately, few treatment options are effective. There are currently three FDA-approved treatments for HS, including adalimumab, secukinumab, and bimekizumab, each with only 40- 60% respond to treatment and over 50% lose response within one year . The overarching goal of this pilot study is to investigate the central hypothesis that oral microbiota transplant therapy(MTT) alters the gut microbiome in patients with Hidradenitis Suppurativa (HS), influencing cutaneous microbiota via systemically absorbed gut-derived metabolites.
