This study will test an experimental Regeneron drug called olatorepatide ("study drug") to see if it can help treat Hidradenitis Suppurativa (HS). In this study, olatorepatide is being tested in people with HS and living with overweight or obesity to see if it helps improve their HS symptoms and quality of life and helps support weight loss. The study is looking at: * What side effects olatorepatide might cause * How well olatorepatide works * How much olatorepatide is in the blood at different times * If the body makes antibodies to olatorepatide, which may cause olatorepatide to not work as well

EPHICACI is a multicenter, prospective study that continues and expands the monocentric PHAGEFORCE registry initiated at UZ Leuven. In Belgium, phage therapy can be applied as standard-of-care only in patients with difficult-to-treat infections where no curative antibiotic and/or surgical alternatives are available ('last-resort cases'). A multidisciplinary phage task force, the Coordination group for Bacteriophage therapy Leuven (CBL), evaluates eligible patients, tests pathogen susceptibility, and sets up standardized treatment protocols. With EPHICACI, this approach is extended to multiple Belgian expert centers to increase patient enrollment while upholding stringent eligibility criteria. The study aims to gain insight into the safety, efficacy, biodistribution and mechanisms of action of phage therapy, and to optimize its use across five medical disciplines (with distinct routes of administration). In addition, EPHICACI integrates machine learning-based phage-bacteria interaction analyses to guide personalized phage selection, and includes health economic evaluations to support evidence-based implementation and reimbursement strategies.

This study will build on data from mice and humans implicating TRPV1 nociceptors in the pathogenesis of the type-17 chronic inflammatory skin disease Hidradenitis Suppurativa (HS). In this study, the investigators will test the hypothesis that inhibiting neuropeptide activity with botulinum toxin reduces pathogenic inflammation.

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.

The goal of this clinical trial is to learn whether a 16-week Mediterranean-style dietary counseling program, called the Med-South Lifestyle Program (MSLP), is practical and acceptable for adults with hidradenitis suppurativa (HS). The study will also look at whether participants' Mediterranean diet adherence changes during the program. The main questions it aims to answer are: * Do participants find the program feasible and practical to follow? * Does adherence to a Mediterranean-style diet change from the beginning to the end of the 16-week program? * Do participants find the program acceptable? All participants will receive the same program; there is no comparison group. Participants will: * Take part in individual nutrition counseling and shorter support calls, mostly by video or telephone * Complete a cooking education session and receive written nutrition materials * Receive Mediterranean-style food support, including pantry staples and prepared meals * Attend two in-person study visits, at the beginning and end of the 16-week program * Complete questionnaires and study assessments and provide biological samples Because this is a pilot study, the information collected will primarily be used to improve the program and help plan a larger future clinical trial.

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

Although it is well known that the clinical expression and course of chronic inflammatory skin diseases are highly variable, there are insufficient epidemiological data on this, and the factors that determine the manifestation, clinical features and course are also largely unknown. There are currently no reliable markers that could predict or delineate patient subgroups to support patient management. The aim of this project is to identify clinical and molecular factors that correlate with disease, disease subtypes and progression through in-depth long-term clinical characterization of patients with chronic inflammatory skin diseases and examination of individual biomaterials.

This is a Phase 2b, global, multicenter, sequential, randomized, double-blind, placebo-controlled, parallel group, dose-ranging study in participants with moderate to severe hidradenitis suppurativa. The purpose of the main study is to assess the efficacy and safety of brivekimig in a dose-ranging study of participants with moderate to severe HS. Study details include: The study duration (per participant) will be up to approximately 164 weeks for participants transitioning into the long-term extension (LTE) period and will be up to approximately 60 weeks for participants not transitioning into the LTE period. The randomized treatment duration will be up to approximately 152 weeks

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.

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.

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.
