Researchers are evaluating new treatments for advanced renal cell carcinoma RCC, a type of kidney cancer. This study compares the effects of combining two targeted therapies, belzutifan and zanzalintinib, against belzutifan with a placebo. The goal is to see if the combination can help people live longer and prevent the cancer from getting worse after other treatments have failed. Participants will take 120 mg of belzutifan orally and either 60 mg of zanzalintinib or a matching placebo once daily for about 24 months. The study is randomized and double-blind, meaning neither participants nor researchers know who receives the active combination or placebo. Two groups are compared belzutifan plus zanzalintinib and belzutifan plus placebo. During the study, participants will be monitored for progression-free survival and overall survival, with assessments up to around 30 to 50 months. Researchers will also evaluate tumor response, duration of response, quality of life, and side effects. Safety and tolerability will be tracked throughout treatment and follow-up periods. The study is sponsored by Merck Sharp & Dohme LLC and aims to provide important information on treating advanced RCC.

Researchers are studying metastatic castration-resistant prostate cancer mCRPC to find new treatment options. This trial evaluates if the study medicine ifinatamab deruxtecan I-DXd or MK-2400 helps people live longer overall and experience slower cancer growth or spread compared to chemotherapy. The study is a Phase 3 trial comparing I-DXd with standard chemotherapy for mCRPC patients. Participants are randomly assigned to receive either I-DXd at 12 mgkg every 3 weeks through intravenous infusion or docetaxel chemotherapy at 75 mgm2 every 3 weeks combined with daily prednisone pills. Treatment continues until the disease progresses, unacceptable side effects occur, or treatment is stopped for other reasons. Premedication is given before each dose of I-DXd to help prevent nausea and vomiting. During the study, participants will have regular visits for treatment and monitoring. Researchers will assess overall survival and radiographic progression-free survival for up to about 36 months. Additional measures include response rates, time to pain progression, PSA progression, and adverse events. The study tracks safety, treatment effects, and quality of life over a long follow-up period to better understand the potential benefits and risks of I-DXd compared to chemotherapy.

This research investigates treatments for metastatic castration-resistant prostate cancer mCRPC focusing on a drug called ifinatamab deruxtecan I-DXd. The study aims to assess the safety, how well participants tolerate the treatments, and appropriate dosing levels of I-DXd alone or combined with other therapies. Researchers will also monitor participants prostate specific antigen PSA levels during treatment to understand its effects. Participants are assigned to one of several treatment groups. One group receives docetaxel every three weeks for up to 10 cycles. Other groups receive I-DXd alone or combined with either opevesostat or androgen receptor pathway inhibitors such as abiraterone acetate or enzalutamide. I-DXd is given every three weeks until unacceptable side effects, disease progression, death, or withdrawal, while the other drugs continue until specific discontinuation criteria are met. Premedication is required before each I-DXd dose to prevent nausea and vomiting. Throughout the study, participants undergo various assessments including monitoring of dose-limiting toxicities, adverse events, and PSA response rates. Researchers also track objective response rates, progression-free survival, overall survival, and other clinical outcomes over up to approximately 54 months. The study involves regular evaluations to assess safety and treatment effects until study completion.

Researchers are studying new treatment options for people with high-risk non-muscle invasive bladder cancer HR NMIBC, including cases with carcinoma in situ CIS. HR NMIBC affects the lining of the bladder but has not spread to muscle or beyond. The study aims to learn if adding intismeran autogene V940 to the standard Bacillus Calmette-Guerin BCG immunotherapy can improve outcomes by helping the immune system attack the cancer more effectively. Participants are divided into groups receiving different treatments. One group Cohort A receives both intismeran autogene via intramuscular injection every 3 weeks for 9 doses and BCG instillations weekly in specific weeks over about 75 weeks. Another group receives only BCG following the same weekly schedule. A third group Cohort B receives intismeran autogene alone every 3 weeks for 9 doses. The study evaluates these treatments over several years. During the study, participants will have regular treatments and follow-up visits where researchers will monitor cancer progression, recurrence, and survival for up to approximately 5 years. Assessments include event-free survival, recurrence-free survival, overall survival, response rates, time to cystectomy, and safety outcomes such as adverse events and treatment discontinuation. The study is randomized and open-label, with detailed long-term monitoring planned.

Researchers are evaluating MK-2214, a study treatment designed to slow brain changes in people with early Alzheimers disease AD. AD is a form of dementia that causes memory loss, communication difficulties, and challenges in decision-making, affecting daily tasks. This phase 2 trial aims to determine if MK-2214 slows the spread of tau protein in the brain compared to a placebo, as well as to assess the safety and tolerability of MK-2214. Participants will be randomly assigned to receive either MK-2214 or a placebo through intravenous IV infusion every 4 weeks during the study. The study uses a parallel design with quadruple masking to compare the effects of the study drug versus placebo over a period of up to approximately 23 months. Both groups receive infusions on the same schedule to maintain the studys integrity. During the study, participants will undergo brain scans including positron emission tomography PET to measure tau protein levels and other assessments such as cognitive and daily living function tests. Researchers will monitor adverse events and treatment discontinuations throughout the study, which lasts up to about 26 months. These assessments help determine the impact of MK-2214 on disease progression and safety in individuals with early AD.

Researchers are investigating new treatments for locally advanced or metastatic urothelial cancer UC, a type of bladder cancer that has spread or cannot be removed by surgery or radiation. This trial evaluates whether sacituzumab tirumotecan sac-TMT, an experimental medicine, can help people with UC who have already been treated with specific therapies live longer compared to those who receive certain non-platinum chemotherapy options. The study is a Phase 3 randomized trial comparing sac-TMT with chemotherapy drugs selected by the investigator. Participants are assigned to one of two groups one receives sacituzumab tirumotecan at a dose of 4 mgkg every two weeks by intravenous infusion until the disease worsens or side effects become unacceptable. The other group receives one of three chemotherapy drugspaclitaxel, docetaxel, or vinflunineby intravenous infusion every three weeks, also until disease progression or unacceptable toxicity. Rescue medications may be given as needed to manage side effects according to approved guidelines. During the study, participants undergo assessments of overall survival up to about 40 months, along with other measures such as progression-free survival, response rates, duration of response, and quality of life evaluations using questionnaires. Safety is monitored by recording adverse events and treatment discontinuations. The total study participation may last several years, with regular evaluations to understand the effects and tolerability of the treatments.

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 studying the potential neuroprotective effects of a dual orexin receptor antagonist DORA called Lemborexant in adults with insomnia. The main goal is to see if this treatment reduces blood biomarkers linked to neurodegeneration, including phosphorylated TAU181, TAU217, amyloid beta 4042 ratio, Neurofilament Light Chain NFL, and Glial Fibrillary Acidic Protein GFAP compared to a placebo. This is a randomized, placebo-controlled crossover study focusing on adults aged 40 to 65 with insomnia disorder. Participants will take 10mg of Lemborexant orally each night for two weeks and a matching placebo nightly for another two weeks, with a 2 to 4 week washout period between treatments. After each treatment phase, participants will visit the research facility for an overnight stay lasting about 18 hours. During this visit, they will undergo various assessments including high-density EEG, functional near-infrared spectroscopy, questionnaires, pupillometry, and blood sample collections. Throughout the study, participants will attend three visits an initial screening and two overnight visits after each treatment period. Blood samples will be collected hourly for four hours following awakening during these visits to measure key biomarkers. Researchers will monitor sleep and brain activity, collect questionnaire data, and evaluate safety. The total involvement includes treatment periods, washout, and overnight assessments, ensuring thorough evaluation of treatment impact on neurodegeneration markers.

Researchers are studying people with idiopathic pulmonary fibrosis IPF or progressive pulmonary fibrosis PPF who have previously taken nerandomilast in another study. The aim is to assess how well patients tolerate long-term treatment with nerandomilast and to evaluate whether it improves lung function and delays worsening symptoms, hospital visits, or death. This open-label extension trial is sponsored by Boehringer Ingelheim and focuses on treatment over an extended period. Participants take nerandomilast tablets for up to 1 year and 10 months while continuing their usual pulmonary fibrosis treatments. The study involves a single treatment group receiving the drug, and no placebo or comparison groups. Regular visits with doctors help monitor health and collect data during this extended treatment phase. Throughout the study, participants undergo regular lung function tests and health assessments to track any adverse events and changes in lung capacity. The main outcome measured is the occurrence of any adverse events for up to about 99 weeks. Secondary outcomes include changes in forced vital capacity and time to worsening of disease symptoms or hospitalization. The study includes ongoing safety monitoring with a total participation time of up to nearly two years.

Researchers are evaluating how changes in diet affect sleepiness, quality of life, and metabolic health in adults living with narcolepsy and idiopathic hypersomnia. This trial focuses on two dietary approaches a whole-food ketogenic diet and a standard whole-food diet, aiming to provide additional lifestyle options beyond medication for managing symptoms. This area of research is new for hypersomnolence conditions but builds on evidence of safety and benefits in other chronic and neurological conditions. The study is a 12-week randomized controlled trial with two groups. All participants start with a three-week period consuming a standard whole-food diet. After this run-in, they are randomly assigned to either continue the standard whole-food diet or switch to a whole-food ketogenic diet that limits carbohydrates to 30-50 grams per day to achieve nutritional ketosis. Both diets focus on unprocessed or minimally processed foods, with the ketogenic diet targeting specific ketone levels monitored through blood and urine tests. Participants will be involved in dietary changes and monitored for feasibility, tolerability, and compliance throughout the 12 weeks. Assessments include measures of sleep quality and sleepiness, metabolic health markers, mood, quality of life surveys, and dietary adherence using ketone levels and sleep diaries. Data collection involves interviews and questionnaires to understand patient experiences and preferences. The study aims to assess whether these diet changes can be sustained and improve health outcomes alongside usual care.
