Researchers are evaluating the long-term safety and effectiveness of the FDA-approved VARIPULSE catheter system for pulmonary vein isolation PVI in adults with symptomatic paroxysmal atrial fibrillation PAF. This device-based study focuses on participants who have not responded well or cannot tolerate at least one Class I or III antiarrhythmic drug and are candidates for catheter ablation. The goal is to monitor the outcomes of using this specific catheter system in managing PAF. Participants will undergo electrophysiology mapping and pulsed field ablation PFA using the VARIPULSE catheter combined with the TRUPULSE generator to perform pulmonary vein ablation. The study is a single-group design where all participants receive this intervention to treat their symptomatic PAF. The ablation procedure is followed by a long-term observation period to assess safety and effectiveness. During the study, participants will be closely monitored for early adverse events within 7 days after the ablation procedure and for freedom from documented atrial tachyarrhythmia episodes from day 61 up to 1095 days post-procedure. Assessments include follow-up testing and compliance with study requirements over this extended period to evaluate both short-term and long-term outcomes. The total study duration extends through 2030, with ongoing safety and effectiveness evaluations.

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.

Alopecia areata AA is a condition where the immune system attacks hair follicles, causing hair loss mainly on the head and face but possibly on other body parts. This research evaluates the safety, effectiveness, and tolerance of upadacitinib, an approved drug, in adolescents and adults with severe AA. The study is a Phase 3 randomized, placebo-controlled, double-blind trial enrolling about 1500 participants worldwide. Participants are randomly assigned to one of three groups receiving different treatments two doses of upadacitinib or placebo. In initial periods, some may switch from placebo to upadacitinib based on their Severity of Alopecia Tool SALT score. Those completing early parts may enter an extension phase receiving upadacitinib for up to 108 weeks. Treatment involves taking oral tablets once daily for up to 160 weeks, with possible re-randomization at Weeks 24 and 52. Throughout the study, participants attend regular clinic visits for medical assessments, blood tests, side effect monitoring, and questionnaires to track treatment effects. Researchers measure hair loss improvement using SALT scores and record adverse events over approximately 164 weeks. Participants are followed for up to 30 days after their last dose for safety monitoring.

Researchers are evaluating treatments for older adults aged 70 and above with advanced stage IIIB-IV non-small cell lung cancer that expresses PD-L1 in 1-49% of tumor cells. This phase III trial compares the effects of adding chemotherapy to immunotherapy with pembrolizumab against pembrolizumab alone. The study aims to assess improvements in overall survival, progression-free survival, response rates, toxicity, quality of life, and explore geriatric assessment factors and gut microbiome correlations. Participants are randomly assigned to one of two groups. Arm A receives pembrolizumab intravenously every 21 days for four cycles, followed by maintenance pembrolizumab every 21 or 42 days for up to two years. Arm B receives the same pembrolizumab schedule plus one of several chemotherapy regimens, including combinations of pemetrexed, carboplatin, nab-paclitaxel, or paclitaxel administered intravenously on different schedules for four cycles, followed by pembrolizumab maintenance. Imaging with MRI, CT, and PET scans is performed at baseline and throughout the trial. During the study, participants undergo regular assessments including imaging scans to monitor disease status, blood tests, and quality of life questionnaires. After treatment completion, follow-up visits occur every three months for up to two years and then every six months up to five years. Researchers measure overall survival as the primary outcome and also track progression-free survival, response rates, adverse events, and patient-reported quality of life. Safety and tolerability are closely monitored along with exploratory analyses of chemotherapy dose intensity and microbiome factors.

Researchers are collecting blood and tissue samples from people with and without cancer to help evaluate new tests that could detect cancer early. This study aims to create a set of blinded blood samples from both cancer and non-cancer patients to validate these tests, focusing on multiple cancer types and stages. The goal is to improve early cancer detection through laboratory research. Participants complete a questionnaire at the start and provide blood samples at registration and again 12 months later. Those diagnosed with cancer may also have tissue samples collected at these times. The study includes patients with various cancer types and stages, as well as individuals without cancer, with some allowing enrollment before full cancer confirmation under specific conditions. During the study, researchers review the collected samples and questionnaire data to assess test performance by tumor type and clinical stage at diagnosis. Participants are followed for one year after completing the study. Key measurements include the provision of a blinded reference set of cancer versus non-cancer blood samples to support future clinical trials focused on blood-based multi-cancer early detection.

This research aims to establish a national biorepository by collecting research data and samples from patients who experience side effects from immunotherapy treatments used in cancer care. It focuses on patients who have serious immune-related reactions, rare infections, or accelerated tumor growth after receiving immuno-oncology therapies. The goal is to help researchers better predict, prevent, and treat these side effects in the future. Participants will have tissue and blood samples collected within 72 hours after confirmation of a serious immune-related side effect and again one month later. For patients experiencing colitis, stool samples may also be collected. Alongside sample collection, medical records will be reviewed for up to one year. This study is observational and involves no experimental treatments. During the study, participants will provide biospecimens at two time points and allow access to their medical records for a year. Researchers will analyze these samples and clinical data to build a resource for future studies on immune-related adverse events. The main outcome is the establishment of this biorepository, which will be maintained for up to one year after enrollment.

Researchers are evaluating how to best recommend chemotherapy for patients with Stage IIB, IIC, or Stage III colon cancer based on the presence or absence of circulating tumor DNA ctDNA after surgery. This Phase IIIII trial explores whether ctDNA status can help guide decisions about the need for adjuvant chemotherapy and identify the optimal chemotherapy regimen for those at high risk of recurrence. Circulating tumor DNA is a promising biomarker that may detect microscopic residual cancer cells that traditional methods might miss. Participants are assigned to groups based on their ctDNA results after surgery. Those without detectable ctDNA ctDNA- may undergo serial monitoring without treatment or receive different chemotherapy regimens such as mFOLFOX6 or CAPOX for 3 to 6 months. Patients with detectable ctDNA ctDNA who have a higher risk of recurrence are randomized to receive either standard chemotherapy regimens like mFOLFOX6 or CAPOX for 6 months or a more intensive regimen called mFOLFIRINOX for 6 months. Central ctDNA testing is performed using the Signatera test to guide these assignments. During the study, participants have blood samples collected for ctDNA testing and undergo imaging scans to check for cancer recurrence. Researchers assess disease-free survival, overall survival, and chemotherapy compliance over several years. The study includes monitoring for safety and treatment effects, with follow-up planned for up to 5 years after randomization. Participants health status, laboratory tests, and tumor markers are regularly evaluated throughout the treatment and follow-up periods.

This research aims to compare two methods of monitoring pancreatic cysts and to identify biomarkers that may help detect the risk of these cysts turning into pancreatic cancer. The study evaluates whether more frequent monitoring or less frequent monitoring leads to better patient outcomes and explores various blood and imaging biomarkers for improved risk prediction. Participants are observed through two different surveillance approaches that were previously randomized but are now closed to new enrollment. One approach involves lower intensity monitoring with MRI, CT, or endoscopic ultrasound EUS scans spaced out over years, while the other involves higher intensity monitoring with more frequent imaging based on cyst size. Throughout the study, patients may also provide blood samples and undergo biopsies, fine needle aspirations, or surgery as needed. Participants are followed up regularly for five years from registration, with imaging and blood tests at intervals depending on their assigned monitoring method. Researchers collect data on clinical features, anxiety, quality of life, financial distress, healthcare costs, and outcomes such as the development of concerning pancreatic cyst features or pancreatic cancer. The study uses these measures to assess the effectiveness of monitoring strategies and the predictive value of biomarkers.

Researchers are investigating treatments for patients with metastatic kidney cancer, focusing on whether adding surgery to a standard immunotherapy-based drug combination improves overall survival. This phase III trial compares outcomes for patients receiving immunotherapy with or without surgery to remove the kidney, known as nephrectomy. Immunotherapy drugs like nivolumab, ipilimumab, pembrolizumab, and avelumab aim to help the immune system attack the cancer, while axitinib works to block tumor growth. The benefit of adding surgery to these drug treatments is not yet established. Participants first receive one of three standard immunotherapy-based regimens before randomization, including combinations of intravenous nivolumab, ipilimumab, pembrolizumab, avelumab, and oral axitinib. After about 10 to 14 weeks of this initial treatment, patients are randomly assigned to continue systemic therapy alone or to receive surgery to remove the kidney plus the same systemic therapy. Surgery may be radical or partial and performed using laparoscopic, open, or robotic methods within 8 weeks of randomization. Axitinib is paused before surgery and resumed after recovery. Throughout the study, participants undergo scans and clinical assessments to monitor tumor response and side effects. After completing treatment, patients are followed up every 3 months during the first year, then every 6 months for years two and three, and annually thereafter for up to seven years. The trial measures overall survival, tumor response in metastatic sites, changes in tumor size, and complications from surgery or drug toxicities. Specimens are also collected for future research to better understand the disease and treatments.
