Participants will receive either icotrokinra or a matching placebo orally every day. The study includes both induction and maintenance phases where researchers assess clinical and endoscopic responses at specific time points, such as Week 12 and Week 40, to determine treatment effects over time. Throughout the study, participants will undergo various assessments including clinical evaluations, endoscopic exams, and safety monitoring. Researchers will measure outcomes like clinical response, clinical remission, and endoscopic healing at Weeks 12 and 40. The study involves regular monitoring to track the participants' health and treatment adherence over the duration of the trial.

Researchers are conducting a Phase 3 multicenter, randomized, double-blind, placebo-controlled trial to assess the safety and effectiveness of navenibart in preventing attacks in adults and adolescents with type 1 or type 2 hereditary angioedema (HAE). This study compares navenibart to a placebo to determine its ability to reduce the frequency of HAE attacks. Participants will receive either navenibart or a placebo as subcutaneous injections. The study treatment period lasts for 6 months, during which the number of investigator-confirmed HAE attacks will be tracked and analyzed to evaluate the treatment's impact. During the trial, participants will be closely monitored for HAE attack frequency and safety. Researchers will collect data on the number of attacks from Day 1 through Day 181 to measure treatment efficacy. Safety assessments will also be conducted throughout the study to ensure participant well-being.

Researchers are studying the effects of DMX-200 (repagermanium), a drug that blocks a receptor involved in inflammation, in people with focal segmental glomerulosclerosis (FSGS) who are also taking an angiotensin II receptor blocker (ARB). This Phase 3 trial aims to assess the safety and effectiveness of DMX-200 compared to placebo over 104 weeks in adults and adolescents aged 12 to 17 years. Following the initial study, an open-label extension will evaluate long-term safety and benefits for up to two more years. Participants will be randomly assigned to receive either DMX-200 at 120 mg twice daily or a placebo, while continuing their ARB treatment. The study includes a screening and qualification period lasting 6 to 14 weeks, a 104-week double-blind treatment phase, and a 4-week follow-up after treatment. Those completing this phase may enter the open-label extension for an additional minimum of 104 weeks, with another 4-week follow-up period, making the total study duration about 230 weeks. During the trial, participants will undergo regular assessments including urine protein and creatinine testing, kidney function monitoring by estimated glomerular filtration rate (eGFR), and safety evaluations. The main outcomes measured are changes in proteinuria, kidney function slope up to week 104, and long-term safety through week 216. Safety will be closely monitored throughout both the double-blind and extension periods to understand the drug's effects over time.

Researchers are evaluating the ability of dapirolizumab pegol (DZP) added to standard care medications to improve moderate to severe systemic lupus erythematosus (SLE) symptoms over the long term. This Phase 3 trial focuses on participants aged 16 and older who have active SLE with specific disease activity and serological markers. The goal is to assess clinical improvement using the British Isles Lupus Assessment Group Disease Activity Index 2004 (BILAG 2004)-based Composite Lupus Assessment (BICLA) at Week 48. Participants will be randomly assigned to receive either dapirolizumab pegol (DZP) or placebo at scheduled times alongside their stable standard of care treatments. Standard medications include antimalarials combined with glucocorticoids and/or immunosuppressants or glucocorticoids and/or immunosuppressants alone if antimalarials are not suitable. The study is double-blind and placebo-controlled, ensuring unbiased comparison between the two groups. Throughout the study, participants will undergo regular assessments to monitor disease activity and treatment safety up to Week 48. Researchers will track responses based on disease activity indices and monitor for any adverse effects. The study includes careful screening and follow-up evaluations to understand the long-term effects of adding DZP to usual care in people with moderately to severely active SLE.

Researchers are evaluating the safety and effectiveness of tulisokibart, a humanized monoclonal antibody, in people with moderately to severely active Crohn's disease. The research includes two studies: Study 1, which has induction and maintenance treatment phases, and Study 2, which only includes induction treatment. The main goals are to see if tulisokibart can help participants achieve clinical remission and endoscopic response compared to placebo, measured at 12 and 52 weeks depending on the study and region (US/FDA or EU/EMA).

Researchers are evaluating the effectiveness of riliprubart compared to a placebo in adults with Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) whose disease has not responded to standard treatments. This is a Phase 3, double-blind, placebo-controlled study focusing on participants with refractory CIDP, including typical and variant forms such as motor CIDP and multifocal CIDP. The study aims to assess response rates over time to better understand the potential benefits and safety of riliprubart for this condition. Participants will receive either riliprubart or placebo administered as a solution via intravenous infusion or subcutaneous injection. The treatment period includes multiple phases with dosing and monitoring planned through 48 weeks. The study includes a screening phase, treatment phases, and follow-up extending up to a total of 111 weeks. Both groups will be monitored for lasting treatment responses, with specific attention to changes from baseline to weeks 24 and 48. During the study, participants will undergo regular assessments to track their disease activity and response to treatment. Evaluations include clinical scoring using the INCAT and CIDP disease activity scores, documentation of vaccinations, and monitoring for adverse effects. Researchers will measure the percentage of participants showing a treatment response and those maintaining that response over time, while also ensuring participant safety through ongoing follow-up and clinical evaluations throughout the study duration.

Researchers are evaluating the effectiveness of riliprubart compared to the usual treatment of intravenous immunoglobulin (IVIg) in adults with Chronic Inflammatory Demyelinating Polyneuropathy (CIDP) who are already receiving maintenance IVIg treatment. This Phase 3 study aims to assess how well riliprubart works and its safety in this population. Participants must meet specific CIDP diagnostic criteria and have a history of responding to IVIg treatment. The study involves administering riliprubart or placebo through intravenous (IV) or subcutaneous (SC) solutions, alongside the usual IVIg treatment. The treatment phase includes a randomized, double-blind comparison of riliprubart versus IVIg, followed by an open-label extension period for continued evaluation. The entire study lasts up to 109 weeks, encompassing screening, treatment, and follow-up phases. Participants will have regular assessments to monitor their response to treatment, including measurements of disability and disease activity scores. Researchers will track the percentage of participants showing a response from baseline to week 24 and those maintaining response through week 48 during the extension. Safety and long-term effects will also be observed throughout the study duration, ensuring comprehensive monitoring of participant health and treatment outcomes.

Crohn's disease is a chronic inflammatory condition affecting the digestive tract that currently has no cure. This research aims to evaluate the safety and effectiveness of upadacitinib in treating moderate to severe active Crohn's disease in a real-world setting in Japan. The study will monitor any adverse events and changes in disease activity among participants. All participants will receive upadacitinib as prescribed by their doctors following local approved guidelines. Around 240 participants will be enrolled, and treatment will be according to each participant's usual clinical care. The study is observational and non-interventional, meaning no additional treatments or procedures beyond standard care will be required. Participants will be followed for up to 64 weeks, with study visits conducted either in person or virtually according to standard care practices. Researchers will assess safety by tracking serious infections related to the drug and monitor disease activity throughout the study period. There is expected to be no extra burden on participants beyond their routine care and assessments.

Researchers are evaluating treatments for newly diagnosed ANCA-associated vasculitis, a serious disease involving inflammation of small to medium blood vessels. This phase 4 trial compares whether avacopan combined with short-term reduced-dose glucocorticoids and rituximab works as well as a longer 20-week reduced-dose glucocorticoid and rituximab treatment for achieving remission. The study also examines if avacopan lowers relapse rates compared to rituximab maintenance therapy and assesses the long-term safety of avacopan. Participants will be randomly assigned to one of two treatment groups. One group receives avacopan with short-term (up to 4 weeks) reduced-dose prednisolone and rituximab given at the start. The other group receives reduced-dose prednisolone for up to 20 weeks combined with rituximab administered at weeks 0, 26, 52, and 78. The study is open-label and will follow patients for up to 104 weeks to compare remission, relapse, and safety outcomes. Patients will be evaluated at multiple time points from baseline through week 104. Assessments include disease status (remission or relapse), disease activity scores, damage indexes, and adverse events. The main outcome is the proportion of patients achieving remission at 26 weeks. Researchers will monitor long-term safety and relapse rates over two years to better understand the benefits and risks of these treatment approaches.

Researchers are evaluating the early use of a once-daily oral drug called empagliflozin 10 mg in patients hospitalized with acute heart failure (AHF) who are at high risk for serious complications. This multicenter, randomized, double-blind, placebo-controlled Phase 3 trial aims to assess the efficacy and safety of empagliflozin compared to a matching placebo in this patient group. The trial focuses on patients requiring intravenous diuretic therapy and exhibiting specific clinical signs and biomarker levels related to heart failure severity. Participants are randomly assigned to receive either empagliflozin 10 mg once daily or a placebo shortly after hospital admission. Treatment begins within 12 hours of hospital presentation and continues during the hospitalization period. The study excludes patients with very low kidney function, recent use of similar drugs, certain heart conditions, and other specific medical issues to ensure safety and clear evaluation of the drug's effects. During the study, patients will be closely monitored for outcomes including death, rehospitalization for heart failure, worsening heart failure during the hospital stay, and urine output within 48 hours of treatment start. Researchers will use a combined measure called the win ratio to assess these outcomes over 90 days. Participants will undergo clinical evaluations, laboratory tests, and safety assessments throughout the study period to track the drug's impact and monitor for any adverse events.
