Researchers are evaluating the effectiveness of amivantamab combined with either lazertinib or platinum-based chemotherapy in treating participants who have epidermal growth factor receptor mutated EGFRm non-small cell lung cancer NSCLC. This study focuses on advanced or metastatic NSCLC cases where standard curative treatments are not suitable. It aims to assess the antitumor activity of these treatment combinations in this patient population. Participants receive either amivantamab with oral lazertinib in 28-day cycles or amivantamab with intravenous chemotherapy consisting of carboplatin and pemetrexed in 21-day cycles. Treatment continues until disease progression, participant withdrawal, death, or investigator decision to stop treatment. The study is designed with two separate groups receiving these distinct treatment combinations. Throughout the study, participants will undergo assessments to monitor treatment effects and safety. Researchers will measure progression-free survival as the primary outcome up to 4 years and 6 months, along with secondary outcomes including dose adjustments, adverse events, overall survival, response rates, and duration of response. Participants are followed regularly during treatment to track these outcomes and manage any side effects until the studys completion.

Researchers are evaluating the addition of Tersolisib LY4064809STX-478 to other anti-cancer drugs as a first treatment for adults with advanced hormone receptor-positive HRhuman epidermal growth factor receptor 2-negative HER2- breast cancer that has a PIK3CA mutation. This Phase 3 randomized, double-blind, placebo-controlled trial aims to understand the efficacy and safety of this combination compared to placebo, focusing on improving outcomes for patients with this specific genetic change. Participants receive LY4064809 orally in one of two doses combined with a CDK46 inhibitor such as Ribociclib, Palbociclib, or Abemaciclib and endocrine therapy ET administered orally or via intramuscular injection. The comparison group receives a placebo combined with the same CDK46 inhibitor and ET. The study includes two parts Part 1 explores dose optimization, and Part 2 evaluates the treatment combinations effectiveness and safety as a first-line therapy. During the study, participants will have regular assessments to monitor cancer response, progression, and safety over an estimated period of up to 5 years or more. Researchers will measure outcomes such as overall response rate, progression-free survival, duration of response, overall survival, and quality of life. Treatment continues as long as the cancer benefits without intolerable side effects. Safety monitoring, laboratory tests, and quality of life questionnaires are part of the participant involvement throughout the trial.

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 the safety and effectiveness of glofitamab, alone and combined with a standard chemoimmunotherapy regimen rituximab, ifosfamide, carboplatin, and etoposide, in children and young adults with relapsed or refractory mature B-cell non-Hodgkin lymphoma B-NHL. This Phase III trial focuses on participants who have not responded to prior treatments or whose disease has returned, aiming to better understand treatment responses and side effects. Participants are assigned to one of two groups. One group receives glofitamab combined with R-ICE chemoimmunotherapy for up to three 21-day cycles. The other group receives only glofitamab for up to twelve 21-day cycles. Additional drugs such as obinutuzumab, rituximab, ifosfamide, carboplatin, and etoposide are given intravenously according to specified schedules. Tocilizumab may be used if needed to manage cytokine release syndrome. Treatment cycles and drug administration days vary depending on the group. Throughout the study, participants attend regular visits for up to three or twelve treatment cycles depending on their group. Researchers will assess tumor response, safety, drug levels in the blood, and immune responses. Outcome measures include complete response rates, adverse events, progression-free survival, overall survival, and other clinical outcomes. The study will follow participants for up to approximately 3 to 4 years to monitor long-term effects and outcomes.

Researchers are evaluating the safety and effectiveness of BGB-16673 compared to pirtobrutinib in adults with relapsed or refractory chronic lymphocytic leukemia CLL or small lymphocytic lymphoma SLL who have previously been treated with a covalent Bruton tyrosine kinase inhibitor cBTKi. The study is a phase 3, open-label, randomized trial sponsored by BeOne Medicines, aiming to assess treatment options for these patients. Participants are randomly assigned to receive either BGB-16673 or pirtobrutinib, both taken orally. This parallel assignment design compares these two drugs directly. The treatments continue with monitoring up to approximately three years to observe progression-free survival and other outcomes. The study began in September 2025 and is expected to complete in April 2028. During the trial, participants will undergo regular assessments including imaging scans to measure disease status, quality of life questionnaires, and monitoring for adverse events. Outcomes such as overall survival, response rates, duration of response, and time to next treatment are tracked. Safety and quality of life will be evaluated throughout the study period, which may last up to about three years for each participant.

Researchers are evaluating the effectiveness, safety, and tolerability of a vaccine designed to reduce Clostridioides difficile C. difficile infections in adults aged 65 years and older. This phase 3 study compares the vaccine to a placebo in a group of older adults who have recent or planned contact with healthcare systems or recent antibiotic use. The purpose is to understand how well the vaccine works to prevent infections and to monitor any side effects or reactions. Participants will receive either the C. difficile vaccine or a placebo shot injected into the upper arm muscle. The study is randomized, double-blinded, and placebo-controlled. The vaccination period includes two doses and participants will be monitored for up to about three and a half years. Follow-up includes three planned clinical visits and three phone visits initially, then yearly clinic visits until the study ends. Participants are asked to report and save stool samples if they experience three or more loose stools in 24 hours to check for possible infection. During the study, researchers will track local and systemic reactions to the vaccine within seven days after each shot, adverse events up to one month after each vaccination, and serious adverse events for up to 18 months after the last dose. The main measurement is the occurrence of medically attended primary C. difficile infections from two weeks after the second vaccination through the surveillance period. Safety monitoring and annual visits will continue until the study is completed, which could be sooner or later depending on infection rates.

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 addition of nivolumab to the usual treatment of paclitaxel and ramucirumab compared to paclitaxel and ramucirumab alone in patients with advanced stomach or esophageal adenocarcinoma. This phase IIIII trial aims to see if nivolumab improves progression-free survival and overall survival in these patients. Nivolumab is an immunotherapy monoclonal antibody that may help the immune system attack cancer, while ramucirumab may prevent tumor blood vessel growth, and paclitaxel stops cancer cells from dividing. Participants are randomly assigned to one of two groups. One group receives nivolumab intravenously on day 1 of each 28-day cycle, combined with ramucirumab on days 1 and 15, and paclitaxel on days 1, 8, and 15. The other group receives only ramucirumab and paclitaxel on the same schedule without nivolumab. Treatment cycles continue unless the disease worsens or side effects become unacceptable. During the study, patients undergo CT scans and MRI imaging, and may optionally provide blood samples. Throughout the trial, participants are monitored with regular imaging and optional blood tests. After treatment ends, patients have follow-up visits at 30, 60, and 90 days, then every six months for up to three years. Researchers assess progression-free survival, overall survival, response rates, disease control, safety, and quality of life using questionnaires and patient-reported symptoms. This comprehensive monitoring helps evaluate treatment effects and patient well-being over time.

Researchers are investigating treatments for patients with stage IV or recurring non-small cell lung cancer who have previously received platinum chemotherapy and immunotherapy. This phase IIIII trial compares the effects of adding cemiplimab, an immune system-stimulating monoclonal antibody, to the usual combination of docetaxel and ramucirumab. The goal is to see if adding cemiplimab helps the immune system better attack tumor cells and improves survival outcomes. Participants are randomly assigned to one of two groups. One group receives docetaxel and ramucirumab along with dexamethasone, while the other group receives these same treatments plus cemiplimab. Treatments are given in cycles every 21 days, with infusions lasting from 30 minutes to an hour depending on the drug. Patients undergo regular blood sample collections and imaging scans such as CT or MRI throughout the study. During the trial, participants are monitored for overall survival, disease progression, tumor response, and side effects. After completing treatment, follow-up visits occur every 3 to 6 months for up to 3 years. Blood tests and imaging help assess treatment effects and safety. Researchers also collect and store blood and tissue samples to support future studies.
