Researchers are evaluating the effectiveness and safety of a combination inhaler containing fluticasone propionate and albuterol sulfate, delivered via a multidose dry powder inhaler with an electronic module, in participants aged 12 years and older with asthma. This Phase 3 trial aims to compare this combination treatment to fluticasone propionate alone, albuterol sulfate alone, or a placebo inhaler. The study also assesses different dosing schedules, safety, tolerability, and pharmacokinetics of these inhalers. Participants will be randomly assigned to one of four groups receiving either the combination inhaler, fluticasone propionate inhaler, albuterol sulfate inhaler, or placebo, all with integrated electronic modules. Treatments are administered over a 4-week period with dosing four times daily. Pharmacokinetic assessments will be conducted after a single dose administration. The study is double-blind and placebo-controlled, with a parallel group design. Throughout the approximately 10-week study period, including screening and treatment, participants will undergo evaluations including lung function tests measuring forced expiratory volume in one second FEV1, asthma control questionnaires, and safety assessments. Researchers will monitor treatment-emergent adverse events and measure blood concentrations of the inhaled drugs. The study includes electronic monitoring of inhaler use and collects data at baseline, during treatment, and at week 4, with follow-up to assess efficacy and safety.

Researchers are evaluating KT-621, an oral drug, for its safety and effectiveness in treating adults with uncontrolled moderate to severe eosinophilic asthma. This Phase 2b randomized, double-blind, placebo-controlled trial aims to understand how KT-621 affects lung function and asthma control compared to a placebo. The study is sponsored by Kymera Therapeutics, Inc. and seeks to provide detailed information on KT-621s behavior in the body and its tolerability. Participants will be randomly assigned to one of four groups receiving different doses of KT-621 or a matching placebo. The treatment period lasts 12 weeks, during which participants take the study drug orally. The trial includes regular assessments to monitor lung function, asthma symptoms, and quality of life, with additional follow-up extending to 16 weeks to evaluate safety and drug levels in the blood. Throughout the study, participants will attend scheduled visits for lung function tests, questionnaires about asthma control and quality of life, and blood sampling to measure drug concentration and monitor safety. Researchers will track changes in lung function from the start through Week 12 and observe any adverse events up to Week 16. Participants are expected to comply with all study visits, treatments, and procedures, including keeping an electronic diary to record relevant health information.

Researchers are evaluating treatments for patients with BRAF-V600 mutant melanoma that has spread to the brain. This phase II trial compares two combinations encorafenib, binimetinib, and nivolumab versus ipilimumab and nivolumab. The study aims to determine which approach is more effective at shrinking and controlling brain metastases, and it also examines survival, response rates, and treatment safety. Patients are randomly assigned to one of two treatment groups. One group takes encorafenib daily by mouth, binimetinib twice daily by mouth, and receives nivolumab through an intravenous IV infusion every 28 days. The other group receives nivolumab IV every cycle and ipilimumab IV over 30 minutes during the first four cycles, with cycles repeating every 21 days initially, then every 28 days. Treatment continues unless disease worsens or side effects become unacceptable. Participants undergo brain MRI scans before enrollment and throughout the study to assess tumor response using specific criteria. After completing treatment, patients are followed every six months for two years, then yearly up to three years. The study collects tissue, blood, spinal fluid, and stool samples for future research. Researchers monitor progression-free survival as the main outcome, along with overall survival, response rates, and treatment side effects.

Researchers are studying two surgical procedures to reduce the risk of ovarian cancer in women with BRCA1 genetic mutations. This trial compares bilateral salpingectomy, which removes only the fallopian tubes, with bilateral salpingo-oophorectomy, which removes both fallopian tubes and ovaries. The goal is to find out if removing just the fallopian tubes with delayed ovary removal is nearly as effective as removing both from the start. Participants choose between two groups one undergoes bilateral salpingectomy with the option of later ovary removal, and the other undergoes bilateral salpingo-oophorectomy. Both groups have imaging tests like pelvic ultrasounds or pelvic MRIs during screening and provide blood samples throughout the study. Follow-up visits occur at multiple time points, including 10 to 60 days, 6 months, 12 months, 24 months, and then yearly for up to 20 years. During the study, researchers track if ovarian or related cancers develop and assess symptoms related to estrogen loss, quality of life, cancer-related distress, sexual function, menopausal symptoms, medical decision making, and any adverse events. Various questionnaires and imaging tests support these evaluations. Long-term safety and cancer risk reduction are monitored for up to two decades after surgery.

Researchers are evaluating how well the 20-valent pneumococcal conjugate vaccine 20vPnC works against pneumonia caused by seven new types of the Streptococcus pneumoniae bacteria. This study focuses on adults aged 65 years and older who are hospitalized with pneumonia confirmed by chest imaging. The study aims to compare the presence of pneumonia caused by these specific bacteria types in people vaccinated with 20vPnC versus those with pneumonia caused by other bacteria or strains. This observational study involves adults 65 years and older hospitalized with radiologically-confirmed community-acquired pneumonia RADCAP. Participants will provide a urine sample for testing pneumococcal bacteria using BinaxNOW and specific urinary antigen detection assays UAD-1 and UAD-2. Cases are identified by detection of the seven additional bacteria types in 20vPnC beyond the previous 13-valent vaccine, while controls include other pneumonia cases without these serotypes. No treatment is given as part of the study. Participants will be involved for about 1 to 2 days for urine sample collection and providing medical history. Researchers will collect detailed information on illness and hospital stay up to 30 days through medical record review. The main outcome measured is the effectiveness of 20vPnC against pneumonia caused by the seven additional bacterial types over approximately 55 months. Other clinical features and pneumonia types will also be reviewed during this period.

This trial investigates monitoring and treatment options for patients with low risk and standard risk metastatic germ cell tumors, which are cancers that start in the cells that produce sperm or eggs. The study aims to find out if active surveillance after surgical removal of low risk tumors can maintain high survival rates, and whether carboplatin or cisplatin chemotherapy works better for treating standard risk tumors in children, adolescents, and young adults. Patients with low risk tumors undergo observation after surgery and may transfer to a standard risk treatment arm if the tumor recurs. Those with standard risk tumors are randomly assigned to receive one of two chemotherapy regimens one containing carboplatin, bleomycin, and etoposide, or the other containing cisplatin, bleomycin, and etoposide. Treatments are given intravenously in cycles every 21 days for up to 3 or 4 cycles depending on the group. Throughout the study, patients have imaging scans, blood tests, tumor biopsies, and pulmonary function tests to monitor response and side effects. Participants are followed closely during treatment and afterward with regular check-ups including CT, MRI, and chest X-rays, as well as blood sample collections. Follow-up visits occur every 2 months for the first year, then every 3-6 months up to 2 years, every 6 months for years 3 to 5, and annually up to 10 years. Researchers measure overall survival, event-free survival, hearing loss, body composition, tumor markers, and patient-reported outcomes related to hearing and neuropathy. This long-term monitoring helps assess the effects and safety of chemotherapy and surveillance strategies.

Researchers are evaluating the safety and effectiveness of the Edwards SAPIEN X4 and X4S Transcatheter Heart Valves THV in people with symptomatic, severe, calcific aortic stenosis. This is a prospective, single group, multicenter study that also includes a separate registry for participants with bicuspid aortic valve morphology. Participants will undergo transcatheter aortic valve replacement TAVR using the SAPIEN X4 or X4S valves. Those with bicuspid aortic valves will be enrolled in a distinct registry but will also undergo TAVR. The study focuses on implantation of these balloon-expandable heart valves as the main intervention. During the study, participants will be monitored for safety and outcomes like death and stroke over one year. Researchers will assess heart function through the Kansas City Cardiomyopathy Questionnaire and check for complications such as paravalvular leak and the need for a permanent pacemaker within 30 days. The total participation time includes follow-up assessments up to one year after valve implantation.

Researchers are studying the effects of adding olaparib, a PARP inhibitor, after surgery and chemotherapy in patients with pancreatic cancer that has been surgically removed and who have mutations in BRCA1, BRCA2, or PALB2 genes. This phase II trial aims to see if olaparib can improve relapse-free survival compared to placebo. The study also evaluates overall survival and differences in outcomes based on mutation type and prior chemotherapy treatment. Participants are randomly assigned to receive either olaparib or a placebo orally twice daily in 28-day cycles for up to 12 cycles, unless the disease progresses or side effects occur. During the treatment, patients will have CT or MRI scans and blood samples taken regularly. After treatment, participants will be followed up at 30 days, every 4 months for the first year, then every 6 months for up to 10 years. Throughout the study, patients will undergo imaging and blood tests to monitor their health and detect any recurrence of cancer. The main outcome measured is the time from randomization to disease recurrence or death. Researchers will also track overall survival for up to 10 years. Safety will be monitored, and participants will be observed regularly after treatment to assess long-term effects and disease status.

Researchers are evaluating the effect of muvalaplin in lowering cardiovascular risks among adults with elevated lipoproteina who either have atherosclerotic cardiovascular disease or are at risk of a first heart attack or stroke. This phase 3, randomized, double-blind study aims to investigate whether muvalaplin can reduce major adverse cardiovascular events compared to placebo in this high-risk population. Participants are randomly assigned to receive either muvalaplin or a placebo, both given orally. The study is designed with parallel groups and will last about 5.25 years, during which the occurrence of cardiovascular events and changes in lipoproteina levels will be closely monitored. Throughout the study, participants will undergo regular assessments including measurement of lipoproteina levels, monitoring of cardiovascular events such as heart attacks or strokes, and evaluation of healthcare resource use. The primary outcome is the time to first major adverse cardiac event, tracked from baseline until the study ends. Safety and pharmacokinetics of muvalaplin will also be evaluated during the trial period.

This research aims to evaluate the combination of two drugs, cabozantinib and nivolumab, in treating advanced melanoma or squamous cell head and neck cancer that may have spread locally or to distant parts of the body. The study focuses on how these drugs affect tumor growth and the immune systems ability to fight cancer. It also investigates how quickly patients can be grouped based on tumor biomarkers, specifically tumor mutational burden and tumor inflammation signature, to understand differences in treatment responses. Participants receive nivolumab through intravenous infusion on the first day of each 28-day cycle and take cabozantinib orally every day. Treatment cycles continue for up to two years unless the disease progresses or side effects become unacceptable. During the study, patients undergo CT or MRI scans and blood sample collections. Tumor biopsies are taken during screening and may be repeated during follow-up. After treatment ends, participants are monitored every 12 weeks for one year and then every six months for up to three years. Throughout the trial, participants are assessed with imaging scans and blood tests to monitor cancer status and treatment effects. Researchers measure the time to receive biomarker results and evaluate tumor response rates. They also track safety, disease control, progression-free survival, and overall survival over the two years of treatment. Specimens are banked for future research. Participants remain under observation for several years after treatment to gather long-term data on outcomes and safety.
