This research aims to evaluate the safety and effectiveness of two dose levels of anvumetostat, a film-coated tablet, in participants with advanced non-small cell lung cancer (NSCLC) that has a specific genetic deletion called MTAP. The study is a Phase 2 trial focusing on participants who have previously been treated for their advanced NSCLC. It also assesses the treatment's effect through independent blinded review to better understand its impact on the cancer. Participants receive anvumetostat as a monotherapy, with dosing schedules tracked closely. The study includes detailed monitoring of drug levels in the blood at various times during treatment cycles to understand how the medicine is absorbed and processed. Treatment continues through several cycles, with specific days designated for blood sampling to measure drug concentration and timing. During the study, participants will be regularly assessed for tumor response using CT or MRI scans according to established criteria (RECIST 1.1). Researchers will also monitor the occurrence of any side effects or adverse events related to the treatment. The study period for measuring outcomes extends up to 35 months, allowing for long-term observation of safety, treatment response, and drug behavior in the body.

Researchers are evaluating the safety and effectiveness of vonoprazan 20 mg taken once daily compared to a placebo in adults with eosinophilic esophagitis (EoE). The main goal is to see how many participants achieve a peak eosinophil count of less than 15 eosinophils per high-power field in the esophagus after 12 weeks of treatment. This is a Phase 2, randomized, double-blind study involving adult participants with EoE. Participants will receive either vonoprazan 20 mg tablets or matching placebo tablets taken orally once daily. The study includes a primary treatment period of 12 weeks, with an additional evaluation of vonoprazan safety and efficacy up to 24 weeks. Treatment is closely monitored to assess the effects on esophageal inflammation. During the study, participants will be monitored through endoscopic biopsies to measure eosinophil counts in the esophagus. They will also complete electronic diaries to document symptoms like dysphagia. Safety assessments and other clinical evaluations will be conducted throughout the study. The primary outcome is the number of participants achieving the target eosinophil count at week 12, with ongoing monitoring to ensure safety and compliance.

Researchers are investigating the safety and tolerability of ASP1002 in adults with metastatic or locally advanced solid tumors that have high levels of the protein claudin 4. This Phase 1 study aims to find a suitable dose of ASP1002 by first testing different dose levels in small groups, then expanding to doses that were safe and effective. Participants have previously been treated with standard therapies or have chosen not to receive them. The study has two parts: Part 1 involves dose escalation with small groups receiving increasing doses of ASP1002 through intravenous infusion every week, every two weeks, or every three weeks in 21- or 28-day treatment cycles. Part 2 uses doses identified in Part 1 to treat new groups. Treatment continues for up to 2 years unless medical issues, cancer progression, new treatments, withdrawal, or missed visits occur. Participants will have regular clinic visits for health and safety checks, including scans (CT or MRI) to monitor cancer status and optional tumor sample collections during and after treatment. After stopping treatment, participants will have follow-up visits within 7 days, then at 1 and 3 months, with health monitoring for up to 1 year after the last dose. Researchers will track side effects, physical exams, lab results, vital signs, ECGs, and performance status over up to 27 months to assess safety and tolerability.

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 the efficacy and safety of SAR441566, an oral tablet medication, in adults with moderate-to-severe ulcerative colitis (UC). This Phase 2, multinational, multicenter, randomized, double-blind, placebo-controlled, dose-ranging study aims to determine how well different doses of SAR441566 help patients achieve clinical remission, measured by the modified Mayo Score, after 12 weeks of treatment. The study includes a screening period lasting up to 28 days plus an additional 7 days if needed. The main treatment period lasts 52 weeks and consists of a 12-week double-blind induction phase followed by a 40-week maintenance phase, ending with a 2-week follow-up after treatment. Participants receive either SAR441566 or a matching placebo orally as tablets. After the main study, eligible participants not joining a long-term study may enter an open-label treatment period for up to 40 weeks. The main study involves 12 visits, and the open-label phase includes 8 visits. During the study, participants will be monitored through clinical assessments and scoring of disease activity. Researchers will track remission rates at week 12 and evaluate long-term safety and efficacy during the maintenance and open-label periods. The total time involved for participants can be up to 59 weeks, including screening, treatment, follow-up, and optional open-label extension.

Researchers are evaluating tulisokibart (also known as MK-7240), a medicine designed to treat active, moderate to severe Crohn's disease and ulcerative colitis, in an extension study. This study includes people who previously took tulisokibart in certain other Phase 2 or Phase 3 studies for these conditions. The main goals are to learn about the long-term safety of tulisokibart and how well people tolerate it over time. Participants in this study will continue receiving tulisokibart, which is a humanized monoclonal antibody given by subcutaneous injection. A matching placebo is also used for comparison. The study focuses on ongoing treatment and monitoring of participants who showed clinical benefit in their earlier parent studies. Female participants who can become pregnant must follow specific pregnancy testing and contraceptive requirements during the study. During the study, researchers will monitor participants for adverse events and any treatment discontinuations due to side effects, tracking these for up to approximately 378 weeks. Safety and efficacy assessments happen regularly, and participants are followed closely to understand the long-term effects of tulisokibart. The total length of participation aligns with continued treatment and safety observation over several years.

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.

Researchers are evaluating the best method to sample patients with known or suspected Barrett's esophagus (BE), a condition that increases the risk of esophageal adenocarcinoma. This trial compares the standard Seattle biopsy protocol with wide area transepithelial sampling (WATS3D) to determine which approach better detects precancerous changes called dysplasia and intestinal metaplasia. Barrett's esophagus can develop into cancer if abnormal cells progress, so early detection is crucial to improve survival rates. Participants will undergo an endoscopic procedure during which they will be randomly assigned to receive either the Seattle biopsy protocol or WATS3D first, followed by the other sampling method. The Seattle protocol involves taking biopsies every 2 cm in four quadrants along the Barrett's segment, while WATS3D uses brushings every 5 cm. If results differ between the two methods, a repeat endoscopy with additional biopsies will be performed. All tissue samples will be reviewed by expert pathologists blinded to patient details. During the study, patients will have an upper endoscopy with high-definition imaging and electronic chromoendoscopy. Researchers will record findings of visible lesions and abnormal patterns. The main outcomes measured are the detection rates of dysplasia and intestinal metaplasia up to one year. The study plans to enroll about 2700 participants across multiple hospitals, with a total duration of about three years including follow-up and analyses to compare the diagnostic accuracy of the two sampling methods.

Researchers are evaluating VE303, a live biotherapeutic product made of eight nonpathogenic bacterial strains, to prevent recurrent Clostridioides difficile infection (CDI). This randomized, double-blind, placebo-controlled Phase 3 trial aims to assess the safety and CDI recurrence rate at 8 weeks in participants receiving a 14-day course of VE303 or a matching placebo. The study includes two stages: one focusing on participants with recurrent CDI and the other on those with primary CDI at high risk of recurrence. Participants will receive either VE303 or placebo capsules that look identical and contain no active drug. The treatment lasts for 14 days, starting on the last planned day of standard antibiotic therapy for the qualifying CDI episode or within 2 days after completing antibiotics. Participants must have completed and responded to standard antibiotic treatment before receiving study medication. The study evaluates the effect of VE303 versus placebo on preventing CDI recurrence after antibiotic therapy. During the study, participants will be monitored through clinical evaluations to track CDI recurrence by Week 8, including stool samples tested for CDI. Safety and clinical response will be assessed throughout the study period. Participants are followed to ensure stability after the qualifying CDI episode and to monitor any complications or adverse events. The total participation duration includes treatment and follow-up through Week 8 to measure CDI recurrence rates and safety.
