Researchers are studying chronic liver diseases and tumors, including non-alcoholic steatohepatitis NASH, non-alcoholic fatty liver disease NAFLD, cirrhosis, and hepatocellular carcinoma HCC. These conditions can be caused by viral infections like hepatitis B, C, and D or lifestyle factors such as overeating and lack of exercise. The goal is to develop better understanding and new treatments by analyzing liver tissues and tumors at the single-cell level to identify therapeutic targets and improve patient outcomes. The study involves creating patient-derived preclinical models, such as spheroid cultures and mouse xenograft models, to test new treatment strategies. Blood samples and tissue biopsies are collected during surgeries, biopsies, or diagnostic tests. Researchers use advanced molecular techniques like single-cell RNA sequencing to examine tumor heterogeneity and the liver environment, aiming to discover new biomarkers and treatment predictors. Participants will undergo procedures as part of their care, including hepato-bilio-pancreatic surgery, biopsies, or locoregional treatments. Blood samples are taken during these procedures to support research. Researchers will monitor surgery outcomes over an average of eight years. By studying patient samples and clinical data, the team aims to improve personalized medicine approaches and identify new preventive and therapeutic targets for chronic liver diseases and liver cancer.

Researchers aim to improve understanding and treatment of brain metastases from solid tumors, which currently have limited systemic treatment options. This study focuses on patients with newly diagnosed non-CNS metastatic solid tumors who are at high risk of developing central nervous system CNS metastases. By gathering detailed clinical and biological information, including analyses of circulating tumor DNA ctDNA from cerebrospinal fluid CSF samples, the study seeks to identify new therapeutic targets and develop innovative treatment strategies. The study is organized into three time periods before the first CNS event Part A, at the first CNS diagnosis Part B, and after the first CNS event Part C. Participants will undergo scheduled collections of plasma, serum, CSF samples, and non-CNS metastatic tumor tissue as applicable, along with brain MRI scans at specific intervals depending on their part in the study. Sample collections and imaging are scheduled annually, every few months, or as clinically indicated, aligned with the participants cancer type and study period. Participants will have regular assessments including imaging and biological sample collections to monitor disease progression and tumor biology. Researchers will analyze the epidemiology and biology of CNS metastases over approximately eight years. Study procedures include lumbar punctures for CSF collection, brain MRIs, and collection of tumor tissue when possible. Participants safety and life expectancy are considered, and follow-up will continue throughout the study duration to support data collection and understanding of CNS metastases.

Idiopathic hypersomnia IH is a rare, chronic disorder marked by excessive daytime sleepiness, long nighttime sleep, and difficulty waking up. It often begins in young adulthood and causes serious social, professional, and economic challenges, leading to accidents and reduced quality of life. There are currently no approved treatments for IH symptoms. This study aims to test a safe treatment combining evening melatonin and morning bright light therapy, which has been effective in related sleep disorders and may improve alertness and mood in IH patients. Participants will receive either an active therapy of one melatonin tablet each evening plus morning bright light therapy, or a placebo consisting of a placebo tablet and placebo light therapy, both over a period of 6 weeks. This randomized, triple-blind trial compares these two groups to evaluate the effects of this combined chronobiological treatment. The study is conducted by the University Hospital in Strasbourg, France. During the study, participants will be monitored and assessed for changes in their IH symptoms using the Idiopathic Hypersomnia Severity Scale at days 14 and 45. The study includes careful screening, adherence to treatment schedules, and safety checks. Participants will be followed throughout the 10 weeks of the study to evaluate treatment impact and tolerability, with all procedures designed to understand if this therapy improves daytime alertness and quality of life.

Researchers are investigating new treatments for metastatic cervical cancer, which is cancer that has spread beyond the cervix, the lower part of the uterus. This study evaluates the safety and effectiveness of the antibody drug conjugate sacituzumab tirumotecan sac-TMT combined with pembrolizumab and bevacizumab. The goal is to find out if these treatments, given together or with some variations, help patients live longer or delay cancer progression compared to standard care. The study has two parts. In Part 1, participants receive sac-TMT, pembrolizumab, and bevacizumab together to assess safety. In Part 2, all participants first get standard induction treatment with pembrolizumab, paclitaxel, and cisplatin or carboplatin, possibly with bevacizumab. Those whose cancer does not worsen then enter maintenance treatment, where they are randomly assigned to receive either pembrolizumab alone or sac-TMT plus pembrolizumab, with optional bevacizumab. Participants are involved for up to about 20 months during maintenance treatment after up to 4 months of induction. The study monitors safety by tracking side effects and treatment discontinuations. Effectiveness is measured by progression-free survival and overall survival up to several years. Quality of life and physical functioning are also assessed through questionnaires. Treatments and evaluations occur through regular intravenous infusions and periodic monitoring visits.

Researchers are studying pulmonary arterial hypertension PAH, a condition where lung blood vessels become thick and narrow, causing high blood pressure in the lungs and making it hard for the heart to work. PAH can cause difficulty breathing and limit activity. While standard treatments help symptoms, they do not stop the disease from worsening. This research focuses on sotatercept, a targeted therapy aimed at specific proteins involved in PAH, to learn about its long-term safety and tolerability when added to usual PAH treatments. Participants in this long-term follow-up study, who previously took part in certain sotatercept trials, may continue receiving sotatercept by subcutaneous injection every three weeks. Those coming from blinded studies start at 0.3 mgkg with possible increases up to 0.7 mgkg, while those from unblinded studies continue their current dose with possible titration to 0.7 mgkg. The study monitors participants over an extended period to assess continued effects alongside their usual PAH therapy. During the study, participants will have regular assessments including monitoring for adverse events, blood tests for blood components and chemistry, body weight, blood pressure, and ECG readings. Researchers will also evaluate exercise capacity, heart function markers, and risk scores related to PAH. The study aims to follow participants for up to approximately 7 to 8 years to understand long-term safety, treatment tolerability, and health changes while using sotatercept with standard PAH care.

Researchers are evaluating the effectiveness and safety of an investigational drug called BNT323 also known as DB-1303 compared with standard chemotherapy in women with recurrent endometrial cancer. The study includes two groups based on the level of HER2 protein in the tumor Cohort 1 with HER2 levels 1 or 2 who have been previously treated with immune checkpoint inhibitors, and Cohort 2 with HER2 level 3. The study aims to understand how well BNT323 or chemotherapy controls cancer progression and how the drug affects patients immune response and quality of life. Participants in Cohort 1 will be randomly assigned to receive either BNT323 or chemotherapy drugs such as doxorubicin, paclitaxel, or docetaxel. In Cohort 2, participants will receive BNT323 alone. Treatments are given intravenously and continue until the cancer progresses, unacceptable side effects occur, or consent is withdrawn. The study includes screening, treatment, safety follow-up, efficacy follow-up, and a long-term survival follow-up lasting up to about 53 months. During the study, participants will undergo regular assessments including tumor evaluations, safety monitoring, and quality of life questionnaires. Researchers will measure progression-free survival in Cohort 1 and tumor response rate in Cohort 2. Safety is monitored by tracking adverse effects and drug levels in the body. Participants can expect to be followed for up to 53 months after treatment to assess long-term outcomes and survival.

Researchers are evaluating the efficacy, safety, and tolerability of subcutaneous ianalumab in adults with diffuse cutaneous systemic sclerosis, a condition characterized by skin thickening and other systemic symptoms. This Phase 2 study compares ianalumab to a placebo to understand its impact on this disease, aiming to provide new treatment options for affected individuals. The study is sponsored by Novartis Pharmaceuticals and employs a randomized, double-blind design to ensure reliable results. Participants receive either ianalumab or placebo through subcutaneous injections during the initial 52-week treatment period. After this, all participants enter a second 52-week open-label phase where they receive ianalumab. Following treatment, there is a post-treatment follow-up lasting at least 20 weeks and up to 2 years to monitor long-term effects. The study includes a screening period lasting up to 6 weeks before treatment begins. Throughout the study, participants undergo regular assessments including measuring response based on the rCRISS25 scale at Week 52, lung function tests, skin scoring, and disability index evaluations. Blood samples are taken periodically to measure drug levels and antibodies. Safety is closely monitored through adverse event reporting up to Week 208. The total participation time can extend over several years including treatment and follow-up phases.

Researchers are evaluating new treatments for advanced ovarian cancer in women who have completed initial surgery and chemotherapy. The study focuses on non-HRD positive ovarian cancer, comparing a targeted therapy called sacituzumab tirumotecan sac-TMT given alone or with bevacizumab, against standard care options such as bevacizumab maintenance or observation. The goal is to see if sac-TMT with or without bevacizumab can help patients live longer without their cancer worsening. Participants in the experimental group will receive sac-TMT through intravenous infusion on days 1, 15, and 29 of every 6-week cycle until the cancer progresses, side effects become prohibitive, or other reasons for stopping arise. They may optionally receive bevacizumab on days 1 and 22 of each cycle. The comparator group will either receive bevacizumab alone every 3 weeks for up to 22 courses or be monitored without active treatment. Supportive medications like steroid mouthwash and other rescue drugs are recommended before sac-TMT infusions. Throughout the study, participants will be regularly monitored for how long they live without their disease progressing, overall survival, side effects, and quality of life using specialized questionnaires. These assessments will continue for up to approximately 78 months. The study is randomized, with single masking, and led by Merck Sharp & Dohme LLC. Participants can expect regular visits for treatment and monitoring during this period.

Researchers are evaluating the efficacy and safety of trontinemab in people with early symptomatic Alzheimers disease, ranging from mild cognitive impairment to mild dementia due to Alzheimers. This Phase III trial aims to understand how trontinemab affects cognitive decline and disease progression in this population. Participants are randomly assigned to receive either intravenous trontinemab or a placebo in a parallel-group design. Treatment is administered by IV infusion, and the effects are compared over a period of 72 weeks. The study includes comprehensive safety and efficacy assessments throughout this period. During the 72 weeks of the study, participants will undergo various evaluations including cognitive tests such as the Clinical Dementia Rating-Sum of Boxes CDR-SB, Alzheimers Disease Assessment Scales, brain imaging with PET and MRI scans, and biomarker measurements in cerebrospinal fluid and blood. Safety monitoring includes tracking adverse events, infusion reactions, and antibody development. The study requires participants to have a study partner and to complete all study procedures over this time.

Researchers are investigating metastatic colorectal cancer mCRC patients who have a specific genetic change called the BRAFV600E mutation. This rare subtype of mCRC often shows poor response to current treatments and has a generally poor outlook. The study aims to collect detailed clinical data and biological samples to better understand this condition, including how patients respond to treatments and what factors predict their survival. It focuses on real-world treatment outcomes and biological markers that might influence therapy choices and resistance. Participants will provide blood samples at multiple times during their treatment, including before and during the first three treatment cycles, at 3 and 6 months after starting each treatment line, and when disease progression occurs following certain therapies. The study gathers up to 390 mL of blood per participant over time to analyze circulating tumor DNA and immune environment factors. This observational approach will help researchers identify biomarkers related to treatment response and disease progression. During the study, participants clinical progress and survival will be tracked for up to five years. Researchers will review overall survival from diagnosis to death and assess how prognostic markers relate to progression-free survival and response to treatments. The study involves collecting tumor tissue samples and blood tests, along with routine follow-up visits. All data collected will contribute to understanding BRAFV600E mCRC and improving future treatment strategies.
