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 the effects of lenalidomide and dexamethasone with or without daratumumab in treating patients with high-risk smoldering multiple myeloma. This phase III trial aims to compare overall survival, progression-free survival, response rates, and safety between these treatments. The study also explores patient-reported quality of life, treatment adherence, minimal residual disease status, and imaging associations during therapy. Participants are randomly assigned to one of two treatment groups. The first group receives daratumumab intravenously on a detailed schedule across up to 24 courses, plus oral lenalidomide daily for 21 days and dexamethasone on specific days during the first 12 courses. The second group receives only oral lenalidomide and dexamethasone on a similar schedule for up to 24 courses. Treatment cycles repeat every 28 days unless disease progression or unacceptable side effects occur. During the study, participants complete quality-of-life questionnaires and undergo laboratory tests, including minimal residual disease assessments and PETCT imaging. Safety is closely monitored, especially infusion-related reactions and toxicity. After treatment, patients are followed for up to 15 years with periodic visits every 3 to 12 months to track long-term outcomes and survival.

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 whether simply observing patients after surgery is as effective as continuing pembrolizumab treatment in preventing cancer recurrence in people with early-stage triple-negative breast cancer TNBC who had a complete response after receiving chemotherapy plus pembrolizumab before surgery. This Phase III trial aims to determine if stopping pembrolizumab post-surgery can maintain recurrence-free survival while potentially improving quality of life and reducing treatment burden. Participants are randomly assigned to one of two groups after finishing chemotherapy with pembrolizumab and surgery. One group continues pembrolizumab intravenously every 3 or 6 weeks for 27 weeks. The other group undergoes observation without further pembrolizumab for the same period. Throughout the study, patients have tumor biopsies and blood collected, along with imaging such as mammography, breast ultrasound, or MRI during follow-up. Participants will be monitored for recurrence-free survival and overall survival for up to 10 years. The study also assesses adverse events, quality of life, financial impact, and work productivity at about 27 weeks after starting the assigned treatment or observation. Safety and treatment effects are tracked through biopsies, imaging, blood tests, and patient questionnaires during the study and follow-up.
