This trial focuses on both women and men diagnosed with Stage I HER2-positive invasive breast cancer. It aims to compare two different combinations of HER2-targeted therapies given after surgery, studying how well each treatment controls the cancer and their side effects. The study is a randomized phase II trial supported by Genentech and led by the Dana-Farber Cancer Institute, evaluating long-term benefits and disease-free survival over several years. Participants are randomly assigned to one of two groups. One group receives six cycles of intravenous trastuzumab-emtansine T-DM1 every three weeks, followed by eleven cycles of subcutaneous trastuzumab every three weeks. The other group receives weekly intravenous paclitaxel for twelve weeks along with subcutaneous trastuzumab every three weeks, continuing trastuzumab alone for additional cycles. The entire treatment period lasts about one year. During the study, participants undergo screening and regular laboratory evaluations along with follow-up visits. Researchers monitor side effects, quality of life, symptoms related to therapy, and cardiac function. The main outcomes measured include the incidence of toxicities during the first 18 weeks and disease-free survival over up to 72 months. Participants are followed for five years after treatment to assess long-term outcomes and safety.

This registry study focuses on patients undergoing extremity amputation procedures to observe how a device is used to freeze nerves during surgery. The purpose is to collect real-world information on the safety and performance of the AtriCure device when applied for nerve cryoablation, a technique that uses extreme cold to temporarily block nerve signals to manage pain, including phantom limb pain. Participants include those who have had or will have an amputation procedure. The study observes the use of cryoablation devices during surgery, which involves applying very cold temperatures to nerves to induce a temporary conduction block. This reversible nerve injury typically lasts weeks to months until nerve sensation is restored. During the study, participants experiences and outcomes are recorded for 30 days post-procedure as the primary outcome measure. Researchers monitor safety and performance data related to the device and nerve freezing treatment. The study runs from April 2025 to April 2035, during which participants provide consent and are followed to assess post-operative and phantom limb pain outcomes.

Researchers are comparing the rates of surgical and minimally invasive interventions, as well as any harms, in Medicare beneficiaries treated with the MILD procedure versus those treated with interspinous process decompression IPD for lumbar spinal stenosis with neurogenic claudication. This observational study uses Medicare claims data to follow patients for 24 months after their initial procedure starting from January 1, 2017. The purpose is to evaluate outcomes between these two types of procedures without requiring prior patient enrollment or consent. The study includes two groups patients who received MILD, which is a percutaneous image-guided lumbar decompression performed under fluoroscopic guidance through a dorsal approach to the spine, and patients who received IPD, a different device-based decompression procedure. Data on reoperations and complications will be collected for both groups over a 24-month follow-up period using Medicare claims. Enrollment continues until the sponsor decides to stop. Participants involvement is passive as the study uses existing Medicare claims data. Researchers will monitor rates of harms related to the initial procedure and subsequent surgical or minimally invasive interventions over two years. No direct patient visits or interventions are conducted, and the study is exempt from institutional review board oversight. The total study duration extends to December 2026, covering cases treated since early 2017.

Researchers are evaluating the addition of pembrolizumab immunotherapy to standard chemotherapy for patients with stage IIA, IIB, IIIA, or IIIB non-small cell lung cancer NSCLC that has been completely removed by surgery. This phase III trial aims to compare disease-free survival and overall survival among different treatment approaches, including chemotherapy alone, chemotherapy followed by pembrolizumab, and chemotherapy combined with pembrolizumab. The study also assesses quality of life and adverse event rates in these patient groups. Participants are randomly assigned to one of three groups. One group receives only chemotherapy with observation afterward. The other two groups receive chemotherapy followed by pembrolizumab or chemotherapy combined with pembrolizumab. Chemotherapy involves one of four platinum doublet regimens administered every 21 days for four cycles, depending on the physicians choice. Pembrolizumab is given intravenously over 25-40 minutes, either after chemotherapy or alongside it, repeated every 21 days or every 6 weeks for multiple cycles. Patients also undergo heart ultrasound, MRI, CT scans, and blood sample collections as part of the study. During the trial, participants have regular medical assessments including imaging and blood tests to monitor their health. Follow-up visits occur 6 weeks after treatment, then every 3 months for 2 years, every 6 months for years 2-4, and annually up to 10 years from randomization. Researchers measure disease-free survival as the main outcome, tracking the time until cancer recurrence or death. They also evaluate overall survival, side effects, drug tolerability, and patient-reported quality of life over time.
