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 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 studying the safety and effectiveness of long-acting antibodies given alone or in combinations to adults with moderately to severely active ulcerative colitis (UC). This Phase 2, multicenter platform trial aims to find treatments that can improve symptoms and induce remission in people diagnosed with UC for at least 3 months. The study includes participants with active disease confirmed by endoscopy and histology and with moderate to severe symptoms based on a scoring system. The trial has two parts. Part A is an open-label phase testing three different monotherapy drugs to assess safety and initial effectiveness. Part B will be a randomized, placebo-controlled phase where participants receive one of six interventions (three monotherapies or three combinations) or placebo to compare outcomes. Treatments involve intravenous (IV) induction followed by subcutaneous (SC) maintenance dosing. Different treatment arms may start and finish at varying times during the study. Participants will undergo endoscopy and histology to confirm disease activity at screening, with regular monitoring throughout the study. Researchers will evaluate changes in disease severity using the Robarts Histopathology Index and measure the percentage of participants achieving clinical remission by Week 12. Safety and efficacy will be closely followed during and after treatment. The total study duration depends on treatment arm timelines and follow-up requirements.

Researchers are evaluating the effectiveness and safety of Afimkibart (RO7790121) as both an induction and maintenance treatment for people with moderately to severely active Crohn's disease in this Phase III, multicenter, double-blind, placebo-controlled study. The goal is to understand how well Afimkibart works compared to placebo in managing symptoms and disease activity over time. Participants will receive either Afimkibart or a matching placebo. Afimkibart is given both as an intravenous infusion and as a subcutaneous injection. This treat-through study means participants continue on the assigned treatment throughout the study period, allowing evaluation of both initial and ongoing therapy effects. During the study, participants will be regularly assessed to measure clinical remission using the Crohn's Disease Activity Index (CDAI) and to check for endoscopic response at week 52. Researchers will monitor safety and treatment effects throughout, with the entire participation lasting up to one year. Assessments include clinical evaluations and endoscopic examinations to track disease changes and treatment impact.

Researchers are evaluating the effectiveness and safety of pegozafermin in adults aged 18 to 75 years who have compensated cirrhosis caused by metabolic dysfunction-associated steatohepatitis (MASH), previously known as nonalcoholic steatohepatitis (NASH). Participants in this phase 3 study must have biopsy-confirmed advanced liver fibrosis (stage F4) due to MASH and meet specific metabolic health criteria. The study aims to understand how well pegozafermin can help improve liver fibrosis and delay disease progression over time. Participants will receive either pegozafermin or a placebo through subcutaneous injections. The study will monitor participants over a long period, up to five years, to observe changes in liver fibrosis and any clinical events related to disease progression. The treatment is given to those with compensated cirrhosis, meaning their liver is damaged but still functioning, and the study carefully evaluates the safety and potential benefits of pegozafermin in this group. Throughout the study, participants will undergo regular assessments to track liver health, including fibrosis regression and timing of disease progression. Researchers will use clinical events and laboratory tests to measure outcomes from the start of the study through 24 months and up to five years. Safety and health will be monitored closely, ensuring any side effects or complications are identified promptly. This comprehensive follow-up helps provide detailed information on the long-term effects of the treatment and participants' liver condition.

Researchers are evaluating the safety and effectiveness of SAR441566 in adults with moderate to severe Crohn's Disease in this phase 2, multinational, randomized, double-blind, placebo-controlled study. The main goal is to compare different doses of SAR441566 against a placebo to see how well they work in treating Crohn's Disease. The study involves participants who have had a confirmed diagnosis of Crohn's Disease for at least three months and have shown moderate to severe symptoms. Participants will take either SAR441566 tablets or matching placebo tablets orally during the study. The study begins with a 4-week screening period, followed by a 52-week main treatment phase that includes 12 weeks of induction treatment and 40 weeks of maintenance treatment under double-blind conditions. After this, a 2-week follow-up is conducted for those not entering the long-term safety study. Eligible participants may join an open-label phase lasting up to 40 weeks, but the combined time in maintenance and open-label phases will not exceed 40 weeks. During the study, participants will undergo assessments including endoscopy to measure response at week 12. Researchers will monitor symptoms, stool frequency, and abdominal pain scores to evaluate treatment effects. Safety will be tracked throughout the study, including a follow-up after treatment ends. The total study duration for participants can be up to 59 weeks, with careful monitoring to ensure accurate evaluation of SAR441566's impact on Crohn's Disease.

Researchers are evaluating whether the medicine tenecteplase helps adults recover from an acute ischemic stroke when given more than 4.5 hours after they were last seen well. This study focuses on people who had a stroke caused by a clot blocking blood flow in the brain and who have imaging showing brain tissue that can still be saved. Participants should not be planning to receive a procedure to remove the clot and must have a pre-stroke disability level of 0 or 1 on the modified Rankin Scale. Participants are randomly placed into two groups. One group receives a single injection of tenecteplase into a vein, while the other group receives standard medical care. The study includes adults aged 18 and over who had an acute stroke or woke up with stroke symptoms more than 4.5 hours ago. Imaging with MRI or CT is used to confirm eligibility. The study lasts about three months, starting with a hospital stay of about one week. During the study, participants have seven clinical examinations or visits to monitor their recovery and health. The last two visits may be done from home to allow remote assessments. Researchers use the modified Rankin Scale to measure disability or dependence in daily activities at 90 days after treatment. They also monitor for any side effects or health changes to compare the effects of tenecteplase against standard care.

This research aims to learn about the safety, how the body processes, and how well the study medicine called nirmatrelvir/ritonavir works for treating COVID-19 in children under 18 years old who are not hospitalized but are at risk for severe illness. The study focuses on pediatric patients confirmed to have COVID-19, with early symptoms and risk factors for worsening disease. Participants will receive the study medicine, which is given by mouth, to evaluate its effects. The trial is open-label, meaning both researchers and participants know the treatment being given. The study is designed as a single-arm Phase 2/3 trial conducted at multiple centers. During the study, researchers will measure medicine levels in the blood at specific times to understand drug absorption and processing. They will monitor for any side effects or adverse events up to 34 days after starting treatment. Vital signs and other health indicators will be regularly checked to assess safety and overall health. The total participation period includes treatment and follow-up to gather comprehensive safety and effectiveness data.

Researchers are evaluating the effects of survodutide in adults aged 18 years and older who have a confirmed liver condition called non-alcoholic steatohepatitis (NASH) or metabolic-associated steatohepatitis (MASH). Eligible participants must have a body mass index (BMI) of 27 kg/m2 or higher, or at least 25 kg/m2 if they are Asian. The study excludes those with other chronic liver diseases or a history of significant alcohol use. The main goal is to see if survodutide can improve liver function and delay progression of liver damage over time. Participants are randomly assigned to receive either survodutide or a placebo, with twice the chance of receiving survodutide. Both treatments are given as weekly injections under the skin using a pre-filled syringe. Alongside treatment, all participants receive regular counseling to encourage healthy diet and exercise habits. The study lasts up to four and a half years, with frequent visits or remote video calls during the first year and five months, then quarterly visits thereafter. During the study, doctors monitor participants' health, including body weight and liver function using imaging tests at certain visits. Participants complete symptom questionnaires to help assess their condition. Researchers track outcomes such as survival, need for liver transplant, worsening liver disease, and liver-related complications. Safety and any side effects are closely watched throughout the study period to understand the treatment's impact.

Researchers are evaluating the effects of survodutide on adults living with obesity who have a liver disease called non-alcoholic steatohepatitis (NASH) or metabolic associated steatohepatitis (MASH), along with moderate or advanced liver fibrosis. The study focuses on whether survodutide can improve liver function and reduce liver damage in these participants. This Phase III trial aims to assess both the effectiveness and safety of survodutide over a long-term period. Participants are randomly assigned to one of two groups: one receiving weekly injections of survodutide and the other receiving placebo injections that look like the medicine but contain no active drug. The doses of survodutide are gradually increased until the target dose is reached. All participants receive counseling to support healthy diet changes and regular exercise throughout the study. The study lasts up to 7 years, with frequent visits to the study site or remote video calls. In the first year, visits occur every 2 weeks, then every 4 to 6 weeks, and later every 3 months alternating between in-person and remote. Throughout the study, researchers monitor participants' health, liver condition through imaging and biopsies, body weight, digestive system effects, and questionnaires about symptoms and quality of life. The main outcomes include liver fibrosis improvement, resolution of MASH without worsening fibrosis, and long-term safety and efficacy measures.
