Researchers are evaluating the long-term safety and effectiveness of the FDA-approved VARIPULSE catheter system in treating people who have symptomatic paroxysmal atrial fibrillation (PAF). This condition involves irregular heart rhythms that start and stop suddenly. The study focuses on how well this treatment manages atrial fibrillation over time using a specialized catheter system. The treatment involves pulsed field ablation using the VARIPULSE catheter combined with the TRUPULSE generator. This device is designed to perform pulmonary vein isolation (PVI) to help control atrial fibrillation symptoms. Participants will undergo this catheter-based procedure as the main intervention during the study. Participants will be monitored closely after the procedure, with researchers tracking early adverse events within 7 days and occurrences of atrial tachyarrhythmia episodes from day 61 up to 1095 days post-procedure. The study includes follow-up testing and assessments to measure safety and effectiveness over an extended period. Participants must comply with all study requirements during this time to help ensure accurate results.

Researchers are conducting a Phase 3 study to compare two front-line treatments for adults with nonsquamous non-small cell lung cancer (NSCLC) that is stage IV or advanced stage IIIB/C. The study focuses on patients whose tumors have a KRAS p.G12C mutation and are negative for PD-L1 expression. The main goal is to evaluate how each treatment affects progression-free survival and overall survival over about 2.5 years. Participants will be randomly assigned to receive either sotorasib combined with platinum doublet chemotherapy or pembrolizumab combined with platinum doublet chemotherapy. Sotorasib is given orally, while pembrolizumab is given intravenously. Both groups will receive the combination therapies as their initial treatment for advanced NSCLC. During the study, participants will be monitored regularly to assess treatment effects and safety. Researchers will track how long patients live without the cancer worsening and overall survival over approximately 2.5 years. The study includes evaluations to determine eligibility and ongoing assessments to monitor health and treatment response throughout the trial period.

Researchers are investigating the addition of an immunotherapy drug called durvalumab to standard chemotherapy treatment in patients with MammaPrint High 2 Risk (MP2) stage II-III hormone receptor positive, HER2 negative breast cancer. This phase III trial aims to compare the effectiveness of usual chemotherapy alone versus chemotherapy combined with durvalumab. Immunotherapy with durvalumab may help the immune system attack cancer cells and prevent tumor growth and spread, while chemotherapy drugs like paclitaxel, doxorubicin, and cyclophosphamide work to stop cancer cells from growing or dividing. Previous studies suggest patients with an MP2 result might respond better to this combined treatment approach. Participants first undergo MammaPrint testing to confirm MP2 status before randomization into two groups. One group receives paclitaxel intravenously on days 1 and 8 every 14 days for 6 cycles, followed by doxorubicin and cyclophosphamide intravenously on day 1 every 14 days for 4 cycles. The other group receives the same chemotherapy schedule plus durvalumab intravenously over 60 minutes on specified cycles during both chemotherapy phases. Mammography is performed during screening, and optional tissue and blood samples are collected for future studies. Throughout the study, participants are monitored through various assessments including imaging, physical exams, laboratory tests, and quality of life questionnaires focusing on fatigue and physical and mental health. Researchers track breast cancer event-free survival and other outcomes such as treatment side effects and response rates. After completing treatment, patients are followed for up to 10 years or until death to evaluate long-term outcomes and safety.

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.

Researchers are evaluating the effect of adding chemotherapy to immunotherapy (pembrolizumab) compared to using immunotherapy alone in treating older adults aged 70 and above with advanced non-small cell lung cancer (stage IIIB-IV). This phase III trial aims to determine if combining chemotherapy with pembrolizumab improves overall survival and other outcomes like progression-free survival, response rates, toxicity, and quality of life in this vulnerable patient group. Participants are randomly assigned to one of two treatment groups. In the immunotherapy-alone group, patients receive pembrolizumab intravenously every 21 days for four cycles, followed by maintenance pembrolizumab every 21 or 42 days for up to two years if there is no disease progression or unacceptable side effects. In the combination group, patients receive pembrolizumab plus a chemotherapy regimen chosen by their doctor, including drugs such as pemetrexed, carboplatin, nab-paclitaxel, or paclitaxel, given intravenously on specific schedules for four cycles, followed by the same pembrolizumab maintenance. Imaging scans like MRI, CT, and PET are performed at baseline and throughout the study. During the study, participants undergo various assessments including imaging scans, laboratory tests, and questionnaires to evaluate treatment effects, side effects, and quality of life. Researchers monitor overall survival for up to five years from randomization, with follow-up visits every three months for the first two years and every six months thereafter until five years. Additional exploratory analyses include safety, tolerability, and correlations with gut microbiome and geriatric assessments to better understand treatment outcomes in this population.

Researchers are collecting blood and tissue samples from people with and without cancer to study and evaluate tests that could help detect cancer early. The goal is to create a blinded reference set of samples to validate blood-based tests for early detection of multiple types of cancer, including leukemia, lymphoma, breast, lung, and others. The study also aims to assess how well these tests perform at the time of initial cancer diagnosis, considering different tumor types and cancer stages. Participants complete a baseline questionnaire and provide blood samples at registration and again 12 months later. Those diagnosed with cancer may also provide tissue samples at these times. The study includes patients aged 40 to 75 years, with cancer diagnoses at various stages or individuals without cancer. Special procedures are in place for patients with high suspicion of certain cancers before confirmation. During the study, researchers collect detailed information through questionnaires, blood draws, and tissue sampling to analyze test accuracy. Participants are monitored for up to one year after registration to follow outcomes. The primary measure is providing this blinded set of blood samples to help validate future cancer detection tests, supporting research that could improve early diagnosis and treatment.

Researchers are evaluating how to best recommend chemotherapy for patients with colon cancer after surgery by using the presence or absence of circulating tumor DNA (ctDNA) in the blood. This approach aims to identify microscopic residual tumor cells and may provide better risk prediction for cancer recurrence compared to traditional methods. The trial focuses on patients with Stage IIB, IIC, or III colon cancer who have undergone complete tumor removal. Participants will have their tumor tissue and blood tested centrally using the Signatera assay to determine ctDNA status. Patients without detectable ctDNA may avoid chemotherapy, while those with detectable ctDNA are considered at higher risk and will be randomly assigned to receive different chemotherapy regimens, including mFOLFOX6, CAPOX, or mFOLFIRINOX, given intravenously or orally over periods ranging from 3 to 6 months. The study includes initial screening, treatment, and possible second randomization for patients whose ctDNA status changes during monitoring. During the study, participants will undergo various assessments including blood tests, imaging scans, and performance evaluations to monitor their health and response to therapy. Researchers will track the time to ctDNA positivity and disease-free survival for up to 3 and 5 years, respectively. Safety and treatment effects will be closely observed throughout the study duration, ensuring thorough follow-up and monitoring for all participants.

Researchers are evaluating two different methods for monitoring pancreatic cysts to determine which approach leads to better outcomes for patients with these cysts. The study compares a lower intensity surveillance schedule with a higher intensity surveillance schedule in patients aged 50 to 75 years. The study also aims to assess differences in surgical complications, pancreatic cancer rates, mortality, costs, healthcare use, patient quality of life, anxiety, financial distress, adherence to surveillance, and the predictive value of biomarkers and radiomic markers for cancer or dysplasia. Participants are randomly assigned to one of two surveillance arms. In the low intensity arm, patients receive MRI or CT scans at the start and one year later, then repeat imaging every two years if no abnormalities are found. If positive features appear, imaging frequency increases. In the high intensity arm, surveillance frequency varies by cyst size, ranging from MRI or CT every six months to combined imaging and endoscopic ultrasound (EUS) every 3-6 months for larger cysts. EUS is used to further evaluate cysts based on size and findings. After imaging procedures, patients are followed for five years from enrollment. During the study, patients undergo procedures including MRI, CT, and EUS, along with quality-of-life and questionnaire assessments. Researchers will monitor clinical outcomes, imaging results, healthcare utilization, costs, patient-reported outcomes, and biomarker performance. Safety and adherence to surveillance schedules will be tracked. The study lasts five years after the initial registration to capture long-term outcomes related to pancreatic cyst monitoring.

Researchers are evaluating if adding adjuvant chemotherapy (ACT) to ovarian function suppression (OFS) plus endocrine therapy (ET) improves invasive breast cancer-free survival (IBCFS) compared to OFS plus ET alone. This Phase III trial focuses on premenopausal women with early-stage breast cancer that is estrogen receptor (ER)-positive, HER2-negative, and has a 21-gene recurrence score between 16-25 for node-negative patients or 0-25 for patients with 1-3 positive nodes. The study addresses the need for better treatment options for younger women diagnosed with this type of breast cancer, as younger age is linked to worse outcomes despite standard therapies. Participants receive one of two treatments: either OFS combined with an aromatase inhibitor (AI) for five years or adjuvant chemotherapy followed by the same OFS plus AI regimen. The specific AI and GnRH agonist used, along with their dosing schedules, are chosen by the investigator, commonly including goserelin, leuprolide, or triptorelin administered monthly or every three months. Bilateral oophorectomy may be used instead of ovarian suppression if preferred. Endocrine therapy beyond five years is at the investigator's discretion. During the trial, participants will be closely monitored for invasive breast cancer-free survival over an 11-year period from randomization. Assessments include clinical evaluations, hormone receptor testing, tumor staging, and genetic recurrence scoring prior to enrollment. Safety and effectiveness data will be collected throughout the study, with particular attention to treatment side effects and long-term outcomes. The trial involves detailed eligibility screening and ongoing follow-up to ensure accurate measurement of the study's primary outcome.
