Researchers are studying how certain factors like age, gender, other medical conditions, and the type of immunotherapy affect whether patients with malignant solid tumors develop mild or serious side effects from immune checkpoint inhibitor treatments. This observational study aims to develop and validate a model that predicts severe immune-related side effects during the first year of immunotherapy, while also assessing quality of life and adverse events over 12 months. The study is sponsored by the SWOG Cancer Research Network and includes translational medicine goals such as evaluating cytokine levels as predictors and establishing a tissue and blood sample repository. Participants will provide a tissue sample at the start of their routine cancer treatment and complete questionnaires at multiple time points at treatment start, and weeks 4, 12, 24, and 52. They may also provide optional blood samples during the study. This design allows researchers to monitor immune-related side effects and patient-reported outcomes over time. During the study, participants will complete various questionnaires to report their quality of life, cognitive function, and side effects. Blood and tissue samples will be analyzed to explore predictive markers of toxicity. Researchers will track the occurrence of severe immune-related side effects over 52 weeks and assess changes in patient-reported outcomes. The study includes ongoing monitoring and data collection, with participation lasting approximately one year from treatment start.

This trial investigates whether tuberculosis preventive treatment TPT given during the window period after exposure can reduce new tuberculosis infections in children and adolescents who live with someone newly diagnosed with pulmonary tuberculosis. The study compares the rate of new infections, measured by IGRA Interferon-Gamma Release Assay conversion at 12 weeks, between those who receive immediate preventive treatment and those who receive standard care where treatment is only given if infection is detected. The goal is to better prevent tuberculosis infection and contribute to global elimination efforts. Participants are assigned to one of two groups. In the intervention group, all children and adolescents receive weekly doses of isoniazid and rifapentine for 12 weeks regardless of their initial IGRA test results. In the control group, only those who test positive on the IGRA test at the start receive this 12-week treatment. Those in the control group who convert to IGRA-positive during the study will also receive treatment following standard care guidelines. During the study, all participants will have IGRA testing at enrollment and again after 12 weeks to detect new infections. Researchers will monitor treatment effects and adverse events related to the 3HP regimen, as well as measure changes in immune response levels. The study lasts 12 weeks with close follow-up to assess the incidence of tuberculosis infection and the safety of the preventive treatment in this young population.
