Researchers are evaluating the safety and effectiveness of tenapanor in adults with Chronic Idiopathic Constipation (CIC) in this 26-week phase 3 study. The study is randomized, double-blind, and placebo-controlled, involving multiple centers. It aims to compare three doses of tenapanor (5 mg, 25 mg, and 50 mg taken twice daily) against a placebo, with a focus on improving spontaneous bowel movements. Participants will first undergo a 2-week screening where their eligibility is assessed through medical history, physical exams, lab tests, ECG, and self-reported constipation symptoms using an electronic diary (eDiary). Eligible patients will then be randomly assigned to receive one of the three doses of tenapanor or placebo twice daily for 26 weeks. During this treatment period, patients will continue daily and weekly symptom reporting via the eDiary and attend regular safety visits at weeks 2, 4, 8, 12, 16, 20, and 26. After completing the 26-week treatment, patients enter a 4-week treatment-free safety follow-up period to monitor any adverse events. A final visit occurs at the end of this follow-up to assess safety. The main outcome measured is the durable complete spontaneous bowel movements response over 12 weeks. Overall, the study involves careful monitoring of symptoms, safety, and treatment effects over approximately 32 weeks.

Researchers are evaluating the long-term safety and effectiveness of abrocitinib, given as a liquid oral suspension, in children aged 2 years and older with moderate-to-severe atopic dermatitis. This Phase 3, open-label study includes children who have previously participated in abrocitinib studies as well as those who have not. The goal is to study up to 500 children globally over a period of up to 2 years or until the medicine becomes commercially available. Participants will receive abrocitinib oral suspension, with or without topical medications, throughout the study. The study consists of two groups: an extension group of children aged 2 to under 12 years who completed prior abrocitinib studies, and a de novo group of children aged 6 to under 12 years new to abrocitinib treatment. Both groups will be monitored for up to 24 months. During the study, children will be regularly assessed through evaluations, including monitoring for any adverse events, laboratory tests, and clinical examinations. Researchers will track treatment-emergent adverse events, serious adverse events, and any events leading to study discontinuation. Safety and efficacy will be closely followed throughout the entire study period to understand the long-term effects of abrocitinib in this population.

Researchers are evaluating whether the drugs retatrutide and tirzepatide can prevent major adverse liver outcomes (MALO) in adults with metabolic dysfunction-associated steatotic liver disease (MASLD) who are at high risk. This Phase 3 trial enrolls about 4,500 adults with MASLD identified by non-invasive tests indicating an increased likelihood of developing serious liver problems. The study aims to understand how these treatments might affect liver health over time compared to a placebo. Participants will be randomly assigned to receive either retatrutide, tirzepatide, or a placebo, all given by subcutaneous injection. The study will last approximately 224 weeks, during which participants may attend 25 to 30 clinic visits for monitoring and assessment. After the main study, eligible participants can join an optional 2-year extension where all will receive either retatrutide or tirzepatide regardless of their original group. Throughout the trial, participants’ liver function and disease progression will be closely monitored through various health assessments. Researchers will track the time to the first major adverse liver event as the main outcome. Safety and health status will be evaluated regularly during clinic visits, ensuring thorough observation over the long study period.

This research aims to evaluate the effectiveness, safety, and tolerability of two doses of remibrutinib compared to placebo in people aged 12 years and older with moderate to severe hidradenitis suppurativa, a chronic skin condition. The study is a phase 3 clinical trial involving participants with a diagnosis lasting at least six months and active symptoms in multiple body areas. The purpose is to determine how well remibrutinib works and how safe and tolerable it is for this condition. The trial lasts a total of 76 weeks and includes several parts: a screening period of up to 4 weeks, a first treatment period of 16 weeks where participants receive either remibrutinib Dose A, Dose B, or placebo in a double-blind manner, followed by a second treatment period lasting 52 weeks during which all participants receive remibrutinib doses. After treatment, there is a 4-week safety follow-up without treatment. Participants stopping treatment early are encouraged to continue in the study and complete the safety follow-up. During the study, participants will be regularly monitored for their response to treatment, including the proportion who achieve a clinical response measure called HiSCR50 at Week 16. Assessments will include physical exams and safety checks throughout the treatment periods and follow-up. The study seeks to gather detailed information on how remibrutinib affects the severity of hidradenitis suppurativa and participants' overall health during and after treatment.

Researchers are evaluating efruxifermin (EFX) in adults aged 18 to 80 who have compensated cirrhosis caused by nonalcoholic steatohepatitis (NASH) or metabolic dysfunction-associated steatohepatitis (MASH). This Phase 3, randomized, double-blind, placebo-controlled study aims to assess the safety and effectiveness of EFX in improving liver health and delaying disease progression in this population. The study focuses on subjects with advanced liver fibrosis (stage 4) but without liver decompensation. Participants are randomly assigned to receive either efruxifermin or a placebo, both administered by subcutaneous injection. The study includes two cohorts: Cohort 1 requires biopsy confirmation of liver fibrosis and specific metabolic features, while Cohort 2 allows biopsy or non-invasive diagnosis. Treatment and observation continue over an extended period to evaluate changes in liver fibrosis and clinical events. During the study, researchers will monitor the time until significant clinical events such as disease progression or liver decompensation occur, with a follow-up of up to five years. For Cohort 1, the proportion of participants showing improvement in fibrosis without worsening steatohepatitis will be assessed at 96 weeks. Participants will undergo regular evaluations including clinical assessments and laboratory tests to track liver function and safety throughout the study period.

Researchers are investigating the safety and effectiveness of efruxifermin in people with non-cirrhotic nonalcoholic steatohepatitis (NASH) or metabolic dysfunction-associated steatohepatitis (MASH) who have moderate to advanced liver fibrosis (stage 2 or 3). This Phase 3 study is randomized, double-blind, and placebo-controlled, enrolling a total of 1650 participants in two groups to evaluate treatment outcomes. Participants will receive either efruxifermin or a placebo by subcutaneous injection. The study involves two cohorts, with Cohort 1 including patients who have biopsy-confirmed NASH or MASH and specific liver fibrosis and activity scores. The treatment period and detailed dosing schedules are not provided but the study compares the effects of the active drug against placebo. During the study, participants will be monitored for improvement in liver disease status, including resolution of NASH/MASH and at least a one-stage improvement in liver fibrosis after 52 weeks for Cohort 1. Long-term outcomes such as event-free survival will be observed over 240 weeks. Safety and efficacy assessments will be conducted throughout the study period, including evaluations of liver histology and metabolic health.

This research aims to evaluate the effectiveness and safety of two different dose schedules of pegozafermin compared to a placebo in adults with metabolic dysfunction-associated steatohepatitis (MASH) who have liver fibrosis at stage F2 or F3. This phase 3 study focuses on improving liver fibrosis and steatohepatitis in this patient group, which involves chronic liver disease associated with metabolic dysfunction. Participants will receive either pegozafermin or a placebo through subcutaneous injections. The study compares two doses of pegozafermin to assess their impact on liver fibrosis and steatohepatitis. The treatment period lasts up to 52 weeks, with outcomes measured at this time point. During the study, participants will be monitored for improvements in liver fibrosis and resolution of steatohepatitis without worsening fibrosis by week 52. Researchers will also track the time until any disease progression occurs, up to 5 years. Throughout the trial, safety and efficacy will be carefully assessed through clinical evaluations and laboratory tests to ensure participant well-being.

Researchers are evaluating the safety and effectiveness of KT-621, an oral drug, in adults and adolescents aged 12 to 75 years with moderate-to-severe atopic dermatitis (AD), a common form of eczema. This phase 2b study aims to assess how well KT-621 reduces the severity and extent of AD, its safety and tolerability, how the drug behaves in the body, and the body's response to the drug. The study includes a 16-week double-blind, placebo-controlled period followed by a 52-week open-label phase. Participants will receive either KT-621 or a matching oral placebo during the initial 16-week double-blind period. Following this, all participants have the option to enter a 52-week open-label period where they receive KT-621. During these phases, participants will continue their regular use of moisturizers twice daily and adhere to the treatment plan. The study is conducted across multiple centers and includes dose-ranging to evaluate different doses of KT-621. Throughout the study, participants will have scheduled visits for assessments including clinical evaluations of eczema severity using the Eczema Area and Severity Index (EASI) score, which measures changes from baseline through week 16. Other evaluations include questionnaires, laboratory tests, and adherence monitoring via an electronic diary. Safety and tolerability are closely monitored, and participants are expected to comply with all study procedures over the entire duration of the trial, including both the double-blind and open-label periods.

Researchers are evaluating the medicine called abrocitinib in children aged 6 to less than 12 years old with moderate-to-severe eczema. This phase 3 study aims to find out if abrocitinib improves eczema symptoms and is safe for this age group. Participants will be randomly assigned to receive either abrocitinib or a placebo for 16 weeks, with the total study lasting about 24 weeks. Participants will receive abrocitinib or placebo as a liquid oral suspension. During the study, children will use an electronic diary on a device resembling a cell phone to record questionnaire responses and receive daily reminders to take their medicine. They will also wear a wrist device to monitor scratching due to eczema. The study includes regular clinic visits and calls from study staff to monitor progress and adherence. Throughout the study, laboratory tests, physical exams, and vital signs (height, weight, temperature, blood pressure, and heart rate) will be conducted to monitor health. Questionnaires will assess eczema severity and improvement using standardized scales. The main outcomes measured at week 12 include skin clearance or near clearance and at least 75% improvement in eczema severity. Safety and overall health will be followed for the entire study duration.

Researchers are evaluating the safety and effectiveness of upadacitinib in treating adults and adolescents with moderate to severe hidradenitis suppurativa (HS) who have not responded to or cannot tolerate anti-tumor necrosis factor (TNF) therapy. HS is an inflammatory skin disease causing painful lesions in areas such as the underarms, groin, and anal/genital regions. This phase 3, double-blind study involves approximately 1328 participants worldwide and aims to monitor disease activity and adverse events over time. Participants will receive oral tablets of either upadacitinib or placebo once daily during Period 1 and Period 2, lasting a total of 36 weeks. In Period 1, participants are randomly assigned to one of two treatment groups, with a 50% chance of receiving placebo. Based on results and placement in earlier periods, participants enter Period 2 with six potential treatment groups. Eligible participants from these periods may continue into Period 3, a long-term extension lasting 68 weeks, continuing the same daily oral treatment. Following the treatment periods, participants will be followed for approximately 30 days. During the study, participants will attend regular outpatient visits for medical assessments, monitoring for side effects, and completing questionnaires. Researchers will measure the percentage of participants achieving a clinical response called HiSCR 50 from baseline to week 16 and track adverse events up to approximately week 108. The study may require a higher treatment commitment compared to usual care, but provides close monitoring of disease activity and safety throughout all study phases.
