Researchers are evaluating the long-term safety and effectiveness of APG777 in adults with moderate-to-severe atopic dermatitis who have completed treatment in a previous APG777 study. This phase 2 extension study involves participants who, according to their doctors, would benefit from continued treatment with APG777. The study is designed as a multicenter, double-blind trial to assess ongoing treatment outcomes and safety over several years. Participants in this study will continue receiving APG777 through three main periods a screening visit coinciding with the last visit of the prior studys maintenance period, an extended treatment period, and a post-treatment follow-up period. Participants who met certain skin improvement criteria and did not use topical rescue medication during the prior study will maintain their previous dose and injection frequency. Those who did not meet these criteria or used rescue medication will receive APG777 according to a specific dosing plan in an open-label escape arm. During the study, participants will be closely monitored for treatment-emergent adverse events up to 3 years. The research team will also measure skin improvements using tools such as the Eczema Area and Severity Index EASI and the Investigator Global Assessment for Atopic Dermatitis vIGA-AD, as well as tracking itch severity, use of rescue therapy, and serum drug concentrations. The overall participation time includes up to 3 years of follow-up to evaluate long-term safety and efficacy outcomes.

This trial evaluates the effectiveness of dotinurad compared with allopurinol in lowering serum uric acid levels in adults with gout-related hyperuricemia. The study focuses on reducing uric acid to below 6.0 mgdL after 24 weeks of treatment, addressing a common complication in gout patients. It is a phase 3, randomized, double-blind study involving adult participants aged 18 to 75 years with a history of gout. Participants are randomly assigned to one of three groups one group continues allopurinol at their existing dose once daily through week 64 the second group receives dotinurad starting at 1 mg once daily for the first 4 weeks, then 2 mg once daily through week 64 the third group begins with 1 mg daily for 4 weeks, increases to 2 mg daily for 8 weeks, then continues 4 mg daily through week 64. All treatments are administered orally as over-encapsulated tablets. Throughout the study, participants undergo regular monitoring of serum uric acid levels and gout flares from baseline up to week 68. Assessments include measuring the percentage of participants achieving target uric acid levels at various points, gout flare rates, and treatment-emergent adverse events. The study also evaluates safety and tolerability over the course of the treatment period, which lasts up to approximately 68 weeks including follow-up.

Researchers are evaluating the efficacy of dotinurad compared with allopurinol in lowering serum uric acid sUA levels in adults with tophaceous gout. This Phase 3 trial focuses on adult participants aged 18 to 75 years who have measurable tophi and a diagnosis of gout for at least one year. The study aims to assess how well dotinurad reduces sUA levels at Week 24 compared to allopurinol, an established treatment for this condition. Participants are randomly assigned to one of two treatment groups. One group will stop their current allopurinol and continue with study-supplied allopurinol once daily through Week 76. The other group will discontinue allopurinol and start dotinurad at 1 mg daily for the first 4 weeks, then increase to 2 mg daily for the next 8 weeks, and finally 4 mg daily thereafter until Week 76. Both treatments are given as oral tablets, and participants are closely monitored throughout the study. During the study, participants will undergo various assessments including blood tests to measure serum uric acid levels at multiple time points, evaluation of tophi response, and tracking of gout flare frequency and severity. Safety monitoring will include recording any adverse events and serious side effects up to Week 80. The main outcome measures focus on the percentage of participants achieving target sUA levels at Week 24 and clinical responses in tophi at Week 76, with ongoing evaluations up to Week 80 to assess longer-term effects and safety.

Hidradenitis suppurativa HS is a painful inflammatory skin condition affecting areas like the underarms, groin, and genital regions. This trial evaluates the safety and effectiveness of upadacitinib, an oral drug approved for other inflammatory diseases, in adults and adolescents with moderate to severe HS who have not responded well or cannot tolerate anti-TNF therapies. The study is double-blinded and involves multiple treatment periods to assess disease activity and side effects. Participants will take oral tablets of either upadacitinib or a placebo once daily during the first two periods, each lasting 36 weeks. In Period 1, participants are randomly assigned to receive either upadacitinib or placebo. Period 2 assigns participants to one of six groups based on their response in Period 1, with treatment continuing for 20 weeks. In Period 3, eligible participants continue their assigned treatment for an additional 68 weeks, followed by a 30-day follow-up. Throughout the study, participants will attend regular outpatient visits where medical assessments will monitor treatment effects and side effects. Questionnaires and clinical evaluations will be completed to measure changes in disease activity and quality of life. The trial aims to track the percentage of participants achieving clinical response and the occurrence of adverse events over the entire study duration, which may be longer than standard care treatments.

Alopecia areata AA is a condition where the immune system attacks hair follicles, causing hair loss mainly on the head and face but possibly on other body parts. This research evaluates the safety, effectiveness, and tolerance of upadacitinib, an approved drug, in adolescents and adults with severe AA. The study is a Phase 3 randomized, placebo-controlled, double-blind trial enrolling about 1500 participants worldwide. Participants are randomly assigned to one of three groups receiving different treatments two doses of upadacitinib or placebo. In initial periods, some may switch from placebo to upadacitinib based on their Severity of Alopecia Tool SALT score. Those completing early parts may enter an extension phase receiving upadacitinib for up to 108 weeks. Treatment involves taking oral tablets once daily for up to 160 weeks, with possible re-randomization at Weeks 24 and 52. Throughout the study, participants attend regular clinic visits for medical assessments, blood tests, side effect monitoring, and questionnaires to track treatment effects. Researchers measure hair loss improvement using SALT scores and record adverse events over approximately 164 weeks. Participants are followed for up to 30 days after their last dose for safety monitoring.

Researchers are evaluating the efficacy and safety of DFL24498, a topical ophthalmic solution, compared with a vehicle solution in adults with dry eye disease.

The study duration is up to 16 weeks and consists of three distinct periods. Participants are assigned to receive either DFL24498 or the vehicle solution, both administered as one drop in each eye four times daily for 12 weeks. The study includes a vehicle-controlled parallel group design. After the 12-week treatment period, there is a 2-week follow-up phase to monitor safety and outcomes. Throughout the study, participants will undergo assessments including corneal fluorescein staining, ocular dryness symptom evaluation using the SANDE questionnaire, tear production measurement with the Schirmer I test, and conjunctival fluorescein staining. Researchers will also track treatment-emergent adverse events. The primary outcome focuses on the change in corneal staining from baseline to week 12, with safety monitored during and after treatment.

The BEATRIX study focuses on healthy pregnant women aged 49 or younger between 24 and 36 weeks of pregnancy to evaluate the safety and immune response of a group B streptococcus GBS vaccine. Researchers aim to understand how this vaccine works in pregnant women and their babies, assessing various safety measures and immune responses related to GBS. This study is a Phase 3, randomized, placebo-controlled, double-blinded trial sponsored by Pfizer. Participants will receive a single injection of either the GBS vaccine or a placebo saline. After birth, a subset of infants will receive routine vaccines according to each countrys immunization schedule, including vaccines for diphtheria, pneumococcal disease, and others. Some infants will have blood samples taken after completing their primary and toddler vaccine doses to evaluate immune responses. Pregnant participants will visit the study site at least three to four times, with some visits possibly conducted by phone, and may stay involved for up to 14 months, including six months after delivery. Their babies will be followed for about 12 months, with a subset participating for up to 19 months. Researchers will monitor local and systemic reactions, adverse events, and antibody levels in both mothers and infants to assess safety and immunogenicity of the vaccine throughout the study period.

Researchers are evaluating the efficacy and safety of ORKA-001 in adults with moderate-to-severe plaque psoriasis. This multicenter, randomized, double-blinded, placebo-controlled phase 2 study aims to identify the best induction dosing regimen of ORKA-001 by comparing three different dose levels with a placebo. The study includes approximately 160 adult participants who have had plaque psoriasis for more than six months and meet specific severity criteria. Participants will be assigned to receive one of three doses of ORKA-001 or a placebo during the induction period, which lasts up to 28 weeks. Following this, they may enter a maintenance period lasting up to about 72 weeks, where three maintenance regimens are evaluated based on participant response. ORKA-001 and placebo are given by subcutaneous injection. After treatment, participants can opt to join an open-label extension study or enter a follow-up period of 48 weeks if they withdraw or do not join the extension. During the study, participants will undergo multiple assessments including skin evaluations using PASI and IGA scores to measure psoriasis severity and improvement. Safety will be monitored throughout the study and during follow-up by tracking adverse events. The primary outcome focuses on the proportion of participants achieving complete clearance of psoriasis at week 16. Total participation may last up to nearly two years, including screening, treatment, maintenance, and follow-up phases.

Researchers are evaluating how binge eating episodes are recorded using two different types of diaries a paper diary and an electronic diary. The study aims to determine if both formats collect information in the same way and to understand which diary type is easier for participants to use. This research addresses the need for reliable and user-friendly tools to track binge eating behavior in adults with Binge Eating Disorder. Participants will complete one diary format for two weeks and then switch to the other format for another two weeks. This crossover design allows comparison between the paper diary completed daily in the evening and the electronic diary accessed via a smartphone app. The study focuses on how these diaries capture binge eating episodes and their usability. During the study, participants will record binge eating episodes daily using each diary format for two-week periods. Researchers will compare the number of binge episodes recorded over 14 days between the two diary types. Participants must own a compatible smartphone to use the electronic diary and will complete self-report measures. The trial includes assessments to confirm binge eating episodes and monitors completion and usability of both diary formats throughout the 30-day participation period.
