Researchers are evaluating zanidatamab combined with chemotherapy to treat people with early-stage HER2-positive breast cancer. This Phase 2 study focuses on patients with Stage II or III invasive breast carcinoma that is confirmed to be HER2-positive. The purpose is to assess the safety and effectiveness of this combination treatment before surgery. Participants receive zanidatamab and chemotherapy drugs such as paclitaxel, docetaxel, carboplatin, trastuzumab, and pertuzumab, all administered intravenously. After completing neoadjuvant therapy, participants agree to undergo either a mastectomy or breast-conserving surgery. The study is open-label and conducted at multiple centers. During the study, researchers monitor the participants' response by measuring the number who achieve a pathological complete response within 8 months. They also ensure participants have adequate organ function, track heart function with imaging, and evaluate treatment safety. Participants are regularly assessed to support study goals and monitor any side effects.

Researchers are evaluating the safety, tolerability, and immune response duration of a second dose of the RSVpreF vaccine given during later pregnancies. The study also examines how long immunity lasts from a single dose given during a previous pregnancy by analyzing blood samples from nonpregnant participants who had the vaccine before. This is a Phase 3 trial focused on pregnant women and their babies as well as nonpregnant women previously vaccinated. Pregnant participants are grouped into Cohort 1, who previously received RSVpreF in a Pfizer trial and will get a second dose, and Cohort 2, who received RSVpreF previously via commercial or trial means and will be randomly given either RSVpreF or placebo. Both groups will be monitored for safety and immune response. Cohort 3 includes nonpregnant women who had RSVpreF before and will provide blood samples to check how long protection lasts, without receiving further vaccination. Participants will undergo safety monitoring during pregnancy and after birth. Infants will be followed for six months to assess safety and antibody levels. Blood tests will measure immune response, including neutralizing antibodies at birth. The study tracks local and systemic reactions, adverse events, serious adverse events, and new medical conditions in both pregnant participants and their infants over various timeframes throughout the study.

Researchers are evaluating AZD0780, an oral PCSK9 inhibitor, in a phase 3, randomized, placebo-controlled study to see if it can reduce the risk of major adverse cardiovascular events (MACE-PLUS) in adults with established atherosclerotic cardiovascular disease (ASCVD) or those at high risk for a first ASCVD event. The study compares AZD0780 to a placebo and monitors participants from randomization until the primary analysis censoring date, followed by a final study closure visit. Participants will be randomly assigned to receive either oral AZD0780 or an oral placebo once daily. The treatment period lasts until the primary analysis censoring date, after which a study closure visit will occur. The study is event-driven and designed to assess the time to the first major cardiovascular event during treatment. During the study, participants will be closely monitored with various assessments to evaluate cardiovascular outcomes and safety over approximately 54 months. Researchers will track the time to first event of any component of MACE-PLUS and collect data to assess the effect of AZD0780 compared to placebo. The study includes regular visits and evaluations to ensure participant safety and adherence to treatment.

Researchers are evaluating the effectiveness of pembrolizumab combined with sacituzumab govitecan-hziy compared to the standard chemotherapy treatments in patients with locally advanced or metastatic urothelial cancer. This Phase III trial focuses on cancers that have spread to nearby tissues, lymph nodes, or other parts of the body. The study aims to compare overall survival and other outcomes such as progression-free survival, response rates, clinical benefits, duration of response, and treatment toxicity between the two treatment approaches. Quality of life and fatigue are also assessed as secondary measures. Participants are randomly assigned to one of two treatment groups. One group receives standard of care chemotherapy, which may include carboplatin or cisplatin combined with gemcitabine, or alternatively docetaxel or paclitaxel, administered intravenously in cycles every 21 days for up to six cycles, unless the disease progresses or side effects become unacceptable. The other group receives sacituzumab govitecan-hziy intravenously on days 1 and 8, along with pembrolizumab intravenously on day 1 of each 21-day cycle, continuing for up to 35 cycles or two years, unless there is disease progression or unacceptable toxicity. Throughout the study, participants undergo regular blood sample collections and imaging scans using computed tomography or magnetic resonance imaging to monitor their condition. Quality of life questionnaires are also completed to assess symptoms and fatigue over time. After treatment ends, patients are followed up 30 days later and then annually for up to five years to evaluate long-term outcomes and safety. The main outcome measured is overall survival from the time of randomization up to five years.

The primary purpose of the study is to assess how well amivantamab in combination with lazertinib or in combination with chemotherapy works (antitumor activity) in participants with epidermal growth factor receptor mutated (EGFRm) non-small cell lung cancer (NSCLC; that is one of the major types of lung cancer).

Researchers are evaluating two treatment combinations for patients with melanoma that has spread to the brain and has a specific BRAF-V600 mutation. This phase II trial compares encorafenib, binimetinib, and nivolumab against ipilimumab and nivolumab to determine which approach better controls and shrinks brain metastases from melanoma. The study also aims to assess overall survival, response rates, treatment duration, and side effects of each regimen. Participants are randomly assigned to one of two groups. One group receives encorafenib orally once daily, binimetinib orally twice daily, and nivolumab intravenously every 28 days. The other group receives nivolumab intravenously and ipilimumab intravenously during the first four cycles, with cycles every 21 days initially, then every 28 days thereafter. Treatment continues unless the disease worsens or side effects become unacceptable. After treatment ends, participants have follow-up visits every six months for two years, then yearly until three years after starting the study. During the trial, participants undergo brain MRIs to monitor tumor response using standardized criteria. Imaging, tumor tissue, spinal fluid, stool, and blood samples are collected for research. Safety and effectiveness are carefully assessed through scans, physical exams, lab tests, and side effect monitoring. Progression-free survival up to three years after randomization is the main outcome. Participants remain in the study for about three years with periodic evaluations to track their health and disease status.

Researchers are evaluating the effectiveness and safety of BHV-7000 in adults with refractory focal onset epilepsy, a condition where seizures originate in one area of the brain and do not respond well to current treatments. This Phase 2/3 clinical trial aims to determine whether BHV-7000 can reduce seizure frequency in this population. The study is divided into two parts. In Part A, participants are randomly assigned to receive either 25 mg or 50 mg of BHV-7000, or a matching placebo, taken once daily. After completing Part A, participants move to Part B, where they are randomized to receive 75 mg of BHV-7000 or a matching placebo, also taken once daily. Both parts are randomized and double-blinded to ensure unbiased results. Participants will be monitored from Week 8 to Week 20 of each part for changes in average seizure frequency, serious adverse events, discontinuations due to side effects, and laboratory abnormalities. Researchers will track seizure diaries and assess safety and tolerability throughout the study. The total duration includes both study parts with regular evaluations to measure the drug’s impact and participant safety.

Researchers are evaluating how effective, safe, and tolerable a vaccine for Clostridioides difficile (C. difficile) infection is in adults aged 65 years and older. The study focuses on reducing the number of C. difficile infections, which can cause diarrhea, in this older adult population. This is a Phase 3, placebo-controlled, double-blinded, randomized trial involving participants who are at risk because of recent or planned contact with healthcare systems or recent antibiotic use. Participants will receive either the C. difficile vaccine or a saline placebo. Both are given by injection into the upper arm muscle. The study includes 3 planned clinic visits and 3 phone visits initially, followed by yearly clinic visits until the study ends. Participants will remain in the study until enough infection events have occurred—this period may last up to about three and a half years, but could be shorter or longer depending on how quickly events happen or if the study stops early due to clear results. Throughout the study, participants will report any side effects such as local reactions and systemic events for 7 days after each vaccination, and adverse events for up to one month. Serious adverse events are monitored for up to 18 months after the last dose. If participants experience 3 or more loose stools within 24 hours during the study, they must save the next stool and contact the study team for infection testing. This ongoing monitoring helps assess the vaccine's impact on preventing medically attended C. difficile infections over time.

Researchers are studying how a single 90-minute session of light to moderate exercise performed within 30 minutes after receiving the initial dose of a COVID-19 mRNA vaccine might affect the immune response. The study also aims to explore whether psychosocial factors like stress, resilience, or depression influence the vaccine's immune response. Participants will be randomly assigned to either an exercise group or a control group that follows their usual daily routine without exercise after vaccination. Those in the exercise group will start a supervised session of brisk walking, walking/jogging, or light jogging adjusted to their fitness level shortly after vaccination. The exercise intensity will be monitored and adjusted based on heart rate and perceived exertion. The control group will continue their day as usual but avoid exercise on vaccination day. Blood samples will be collected before vaccination and at several points up to 12 months after to measure antibody levels, T cell responses, gene expression, and metabolite profiles. Participants will also complete surveys assessing physical activity, stress, resilience, and depression. Participants will report any side effects for three days after vaccination. Blood samples will be analyzed for immune responses including antibody and T cell activity, gene expression by RNA sequencing, and serum metabolites. Researchers will compare immune responses between the exercise and control groups and explore links between psychosocial factors and immunity. The study involves multiple follow-up visits over one year to track changes in immune response and related biological markers.

Researchers are evaluating the addition of olaparib, a PARP inhibitor, as maintenance therapy following surgery and chemotherapy in patients with pancreatic cancer that has been surgically removed and who have a pathogenic mutation in BRCA1, BRCA2, or PALB2 genes. This phase II randomized, double-blind study aims to determine if olaparib can improve relapse-free survival compared to placebo in these patients, who have completed perioperative chemotherapy and have no evidence of recurrent disease. Participants are randomly assigned to receive either olaparib or a placebo orally twice daily in 28-day cycles for up to 12 cycles, as long as there is no disease progression or unacceptable side effects. Throughout the treatment period, patients undergo imaging tests such as CT scans or MRI and blood sample collections. After completing the treatment cycles, patients are followed up at 30 days, every 4 months for the first year, and then every 6 months for up to 10 years after randomization to monitor their health and disease status. During the study, researchers assess relapse-free survival by documenting any return of cancer or death from 22 to 44 months after randomization. They also collect blood samples and perform imaging tests to monitor the disease and evaluate treatment effects. Safety is carefully monitored, and patients must have recovered from previous treatments before starting the study. The study includes long-term follow-up to observe survival outcomes and any differences based on genetic mutations or prior chemotherapy regimens.
