Hidradenitis Suppurativa

Researchers are studying the safety and effects of a medicine called Ritlecitinib for adults with moderate to severe hidradenitis suppurativa (HS), a condition causing long-lasting painful red skin lumps. The study focuses on participants who have not responded well to antibiotics or could not tolerate them. This is a phase 2, randomized, double-blind, placebo-controlled trial to evaluate how well Ritlecitinib works compared to a placebo. Participants will be randomly assigned to receive either Ritlecitinib or a placebo pill that looks the same but contains no medicine. Those in the treatment group will take an oral loading dose once daily for 8 weeks, followed by a maintenance dose once daily for another 8 weeks. The placebo group will receive matching placebo pills on the same schedule. The total study duration is about 16 weeks. During the study, participants will attend about 10 clinic visits including screening, Day 1, and follow-ups every 1, 2, or 4 weeks until week 16. At each visit, health status will be checked through physical exams, blood and urine tests, vital signs, chest X-rays, ECGs, hearing tests, and questionnaires. Participants will also use an electronic diary on their mobile phones to record daily medication intake and HS symptoms. The main measurement is the proportion of participants achieving a 50% reduction in HS symptoms by week 16. Safety and other symptom improvements will also be monitored.

Researchers are evaluating camoteskimab, a drug being studied in adults with moderate-to-severe atopic dermatitis. This phase 2b study is multicenter, randomized, double-blind, and placebo-controlled, aiming to assess the drug's effects compared to placebo. Participants include those who have not been treated before and those who have had an inadequate response to previous biologic therapies. The study has two parts: Part 1 is a 24-week period where participants are randomly assigned to one of four groups receiving one of three doses of camoteskimab or a placebo, all given by subcutaneous injection. In Part 2, an extension period, all participants will receive camoteskimab. This design allows researchers to compare the drug doses with placebo initially and then provide treatment to all participants. Participants will be involved for at least 24 weeks in the placebo-controlled phase and beyond during the extension. They will undergo assessments including the Eczema Area and Severity Index (EASI), Investigator Global Assessment (IGA), and peak itch ratings. Researchers will measure changes in eczema severity, itch intensity, and skin condition over time. Safety and adherence will be monitored throughout the study period to evaluate the drug's effects and tolerability.

Takayasu arteritis (TAK) is a rare chronic inflammatory disease affecting arteries, and there is no widely accepted effective treatment strategy. Researchers classify TAK patients into three severity levels: mild, moderate, and severe. This study focuses on severe TAK patients and compares two biological agents, tocilizumab and adalimumab, to find which treatment may provide better intervention outcomes in this group. The study randomly assigns severe TAK patients to receive either tocilizumab at a dose of 8mg/kg intravenously every four weeks or adalimumab at 40mg biweekly by injection for 24 weeks. Patients start with prednisone at 40mg daily, tapered gradually over months, and treatment adjustments are made if disease relapse occurs. After 24 weeks, if remission is not achieved, patients switch to the other biological agent for an additional 24 weeks. Participants are monitored throughout treatment and follow-up for disease remission using clinical and laboratory assessments. Researchers track disease relapse, vascular progression through angiographic exams, prednisone dose reduction, and quality of life changes using questionnaires over a total of 48 weeks. The primary outcome is disease remission at 24 weeks. Safety and disease activity are closely observed during the study.

Researchers are evaluating and comparing the effectiveness and safety of two treatments, secukinumab and tofacitinib, in adults with moderate to severe hidradenitis suppurativa (HS). The study aims to find out which treatment works better for this condition and to understand the medical problems participants may experience with each drug. Participants will be adults aged 18 to 75 years with moderate to severe HS, specifically Hurley stage II or III, who have had an inadequate response or intolerance to previous antibiotic treatments. Participants will be randomly assigned to one of two groups. One group will receive secukinumab 300 mg by injection every week for the first month and then every four weeks for up to one year. The other group will take a daily 11 mg tablet of tofacitinib for one year. During the study, participants will visit the clinic every two weeks for the first month and then every four weeks for checkups and tests. Throughout the trial, participants will keep a diary to track their symptoms. Researchers will assess clinical response using the Hidradenitis Suppurativa Clinical Response (HiSCR) at 12 weeks and again at one year. They will also monitor the frequency and severity of any adverse events during the study. Safety and effectiveness will be evaluated over the full one-year treatment period, with regular laboratory tests and follow-up visits to ensure participant well-being.

Researchers are studying the impact and burden of three skin conditions: moderate or severe alopecia areata, non-segmental vitiligo, and moderate to severe hidradenitis suppurativa. The study includes adolescents and adults and aims to understand how these conditions affect quality of life and daily functioning in a large global population. This is an observational study where participants with each condition will have a single visit for data collection following routine clinical practice. No experimental treatments are given; instead, the study gathers information during this one visit to assess disease characteristics and impact. During the visit, participants will complete questionnaires and clinical assessments specific to their condition. These include tools measuring symptom impact, hair loss severity, skin depigmentation, and quality of life related to each disease. This helps researchers better understand the real-world burden of these conditions. Participation involves only this one visit, with no long-term follow-up or additional procedures.

Researchers are evaluating LT-002-158, an oral IRAK4 protein degrader being developed to treat autoimmune diseases and inflammation, including Hidradenitis Suppurativa and Atopic Dermatitis. This first-in-human Phase 1 study aims to assess the safety, tolerability, and how the drug is absorbed and processed in the body (pharmacokinetics and pharmacodynamics) in healthy adult volunteers. The study also examines how food intake affects the drug's absorption. The trial includes three parts: Part 1 involves single ascending doses where groups of healthy volunteers receive either LT-002-158 or placebo, starting at 50 mg, with doses increasing if tolerated. Part 2 is a crossover study with healthy volunteers receiving a single dose of LT-002-158 under different food conditions (fasted, standard meal, and high-fat meal) to evaluate food effects. Part 3 involves multiple ascending doses given daily for 14 days, with dosing levels determined based on earlier safety and pharmacokinetic data. Participants will be closely monitored through physical exams, vital signs, ECGs, laboratory tests, and pregnancy tests for women. Researchers will track safety and how the drug behaves in the body up to 28 days after dosing. Volunteers must comply with scheduled visits and procedures throughout the study, which is expected to run until June 2025.

This research aims to evaluate the accuracy of the Belle.ai software in diagnosing common dermatologic diseases across different skin tones. The software uses deep learning technology to analyze clinical images of skin conditions and provides a differential diagnosis from a database of over 2,000 skin conditions based on more than 500,000 images. The study will determine how well the AI-generated diagnoses match those of dermatology experts. Participants who consent will have three images taken of their skin condition using the Belle.ai software. These images will be de-identified and uploaded into the system, where the software will generate a single list of possible diagnoses. Dermatology experts will then review the cases to compare their diagnoses with the AI results. The study will be conducted at dermatology clinics within the Advocate Health system. During the study, images will be captured and uploaded securely without any personal identifiers. The Dermatologic Review Committee will assess the concordance between the AI's primary diagnosis and expert opinions, aiming for greater than 80% agreement. Participants will not need to complete any additional forms, and their involvement primarily involves image capture during their clinic visit. The main outcome measured is the agreement between AI and physician diagnoses on the day of image capture.

Researchers are evaluating topical roflumilast 0.3% foam as a treatment for patients with Hidradenitis Suppurativa (HS), a skin condition involving inflammatory lesions. This phase 2a, open-label study explores its safety and effectiveness both as a stand-alone treatment for mild HS and as an add-on therapy for moderate to severe cases. The study includes gene expression analysis to understand changes before and after treatment. Participants will apply topical roflumilast foam once daily to affected areas. Those with mild HS (Hurley stage I) will use it as monotherapy, while patients with moderate to severe HS (Hurley stage II or III) will add it to their stable existing treatments. The treatment period lasts 4 months, with gene expression profiling performed to assess molecular changes resulting from therapy. Participants will undergo evaluations including gene expression testing via tape strip collections at baseline and week 16. Other assessments will measure treatment response, quality of life, and pain levels at baseline, 1 month, and 4 months. Safety and tolerability will be monitored throughout the study, which runs from screening through 4 months of treatment to understand how the foam affects HS symptoms and patient well-being.

Researchers are evaluating adalimumab for patients with acute Vogt-Koyanagi-Harada (VKH) disease to test if it provides clinical benefits. This observational study divides participants into two groups: one receiving adalimumab therapy and the other receiving traditional treatment with glucocorticoids alone or combined with immunosuppressants. The study follows ethical guidelines and informed consent was obtained from all patients. In the adalimumab group, patients receive an initial subcutaneous dose of 80 mg, then 40 mg every two weeks. Therapy continues for six months after ocular inflammation subsides, followed by tapered injections until withdrawal after 40 days. The traditional therapy group follows glucocorticoid treatment starting at 1 mg/kg/day, gradually stopped over 90 to 180 days. The study lasts up to one year to track treatment outcomes and side effects. Participants undergo regular assessments including best corrected visual acuity (BCVA), anterior chamber and vitreous inflammation, optical coherence tomography (OCT), and corticosteroid dose changes. Researchers monitor anti-inflammatory and immunosuppressive effects of adalimumab, visual acuity changes, and recurrence rate at 24 weeks. Prednisone exposure is also tracked over 12 months to evaluate treatment impact and safety throughout the study period.

Researchers are evaluating the safety and effectiveness of baricitinib for treating severe or very severe alopecia areata, a condition causing hair loss, in children aged 6 to less than 18 years. This Phase 3 clinical trial aims to determine how well baricitinib works in this young population, with careful monitoring of outcomes related to hair regrowth and patient well-being. Participants will be randomly assigned to one of three groups: a high dose of baricitinib, a low dose of baricitinib, or a placebo. The study includes four periods: a 5-week screening phase to determine eligibility, a 36-week double-blind treatment period where participants receive their assigned treatment, an approximately 2-year long-term extension to observe longer-term effects, and a 4-week follow-up after treatment ends. Some participants may continue to receive treatment after the extension for up to 180 weeks. During the trial, children will undergo regular assessments including the Severity of Alopecia Tool (SALT) score to measure hair loss, patient-reported outcomes on scalp hair, eyebrow, and eyelash hair, as well as evaluations of anxiety, depression, and quality of life. Blood tests will monitor drug levels and immune response. Participants will be closely followed throughout the study periods to track changes and ensure safety, with the total participation lasting over two years depending on extension eligibility.
