Researchers are evaluating the use of carboplatin chemotherapy given before surgery in patients with high-risk prostate cancer who have inherited mutations in the BRCA1 or BRCA2 genes. This phase II trial aims to determine how well carboplatin works in shrinking tumors prior to surgery and to assess its impact on disease progression and survival. The study also monitors treatment side effects and collects tissue samples for future research. Participants receive carboplatin intravenously before undergoing prostate surgery. Those who show signs of disease progression after surgery will have imaging tests such as CT, MRI, chest X-ray, or PSMA PET scans. Blood samples are collected throughout the trial to monitor health and support additional studies. The study includes detailed follow-up to evaluate treatment outcomes and safety. During the trial, participants will have regular assessments including physical exams, PSA tests, and imaging scans if needed. Researchers will review the rate of complete tumor response after carboplatin treatment at surgery and track progression-free survival and overall survival over time. Safety and side effects of the treatment are closely monitored. Participation may last up to five years with ongoing collection of health data and specimens.

Researchers are evaluating different combinations of drugs to treat newly diagnosed multiple myeloma in patients who are not eligible for stem cell transplant and are considered frail or intermediate-fit based on age, other health conditions, and functional status. This phase III trial compares three induction regimens followed by either single or double maintenance therapy to see which combination works best to control the cancer and improve survival. The study also examines patient quality of life, safety, and other treatment effects over time. Patients are randomly assigned to one of three treatment groups. The first group receives bortezomib, lenalidomide, and dexamethasone for up to nine 28-day cycles, followed by lenalidomide maintenance. The second group receives daratumumab and hyaluronidase-fihj, lenalidomide, and dexamethasone for induction, followed by lenalidomide maintenance. The third group has the same induction as the second group but receives both daratumumab and lenalidomide during maintenance. Treatments are given by injection or orally on specific days within each cycle, and continue as long as the disease does not progress or side effects are unacceptable. Participants undergo assessments including tumor measurements, blood tests, patient-reported questionnaires, and blood sample banking for future research. After completing treatment, patients are followed up every three months for one year, then every six months for two years, and annually for up to ten years to monitor progression, survival, and quality of life. The main outcomes measured are progression-free survival and overall survival, with additional evaluations of response rates, safety, and symptom reports up to ten years after starting the study.

Researchers are gathering ongoing information on the safety and performance of Medtronic products that are already available on the market. This registry study aims to support patients, hospitals, clinicians, regulators, payers, and the medical industry by simplifying the process of monitoring these products and providing up-to-date performance data. The study involves collecting data on patients who have received or are planned to receive Medtronic medical devices or therapies. Enrollment includes both prospective and retrospective participants within a specific time frame related to their therapy start. There are no specific interventions assigned, as this is an observational registry. Participants provide written consent and are followed periodically, typically every 6 to 12 months depending on the therapy, to assess the safety and effectiveness of their Medtronic product. Researchers collect information from medical records and follow-up visits to monitor outcomes over time. Participants may be followed for many years, with the study currently planned through January 2040.

Researchers are evaluating patients with metastatic HER-2-positive breast cancer who are receiving trastuzumab-based therapy and are at risk of heart problems. The study includes two groups: one large observational group taking beta blockers, ACE inhibitors, or ARBs alongside trastuzumab, and a smaller randomized group comparing the effects of carvedilol versus no treatment. The aim is to understand the occurrence of heart issues and whether carvedilol might help prevent cardiac side effects from chemotherapy. Participants are assigned to one of three arms based on their current medications. Patients not on beta blockers, ARBs, or ACE inhibitors are randomized to either receive carvedilol orally twice daily or no study intervention. Those already taking these heart medications enter an observational arm without additional treatment. Treatment and observation continue for up to 108 weeks unless disease progression or unacceptable side effects occur. Throughout the study, participants undergo heart function monitoring with echocardiograms every 12 weeks and provide blood samples for biomarker analysis. Researchers track the time to the first sign of heart dysfunction and any cardiac events, as well as adherence to medication and side effects. The study also collects data to develop models predicting heart risk and banks samples for future research. Participant involvement may last over two years with regular assessments to monitor safety and heart health.

Researchers are evaluating how well serum tumor marker directed disease monitoring (STMDDM) works compared to usual care in patients with hormone receptor positive, HER2-negative metastatic breast cancer. This trial aims to see if monitoring with serum tumor markers can provide similar overall survival outcomes to the standard approach, which involves regular imaging scans. The study also looks at healthcare costs, patient anxiety, and quality of life related to these monitoring methods. Participants are randomly assigned to one of two groups. In the usual care group, patients receive imaging studies at least every 12 weeks and may have serum tumor marker tests as determined by their doctor. In the STMDDM group, patients have blood tests for specific tumor markers every 4 to 8 weeks, and imaging scans are only done if these markers indicate a possible progression of disease. Both groups continue their monitoring for up to 312 weeks unless the disease progresses. During the study, participants undergo regular assessments including blood tests for tumor markers, imaging scans as needed, and questionnaires about anxiety and quality of life. Researchers track overall survival for up to 312 weeks and compare healthcare costs and patient-reported outcomes for up to 48 to 102 weeks. The study also collects data on how often and by what methods disease monitoring is performed, along with patient and physician preferences related to monitoring.
