The purpose of this research study is to determine if an already FDA approved drug called atorvastatin can help adults, age 75 or older, live well for longer by preventing dementia, disability, or heart disease. Participants will be assigned by chance to receive either atorvastatin (study drug) or a matching placebo (a tablet that looks like atorvastatin but does not contain any medicine). Study engagement may last up to five years and involves in clinic and/or remote visits, survey questions, potential blood draws, in addition to memory and physical tests. After the first 1-2 visits performed in clinic or remote, the study team will follow-up via phone on a yearly basis to see how participants are doing. Participants will be compensated for their time and participation in this research study.

This proposal is to contribute to data registry and sample bank called Pediatrics Biorepository for Gastroenterology Clinical Research. Samples collected in this study may be used for future research which plan to advance the state of science in the hopes to develop novel diagnostic approaches and identify therapeutic targets.

This is a study for patients with relapsed/refractory large B-cell lymphoma or follicular lymphoma. Patients who have either stable disease or a partial response to CD19 CAR T-Cell therapy may be eligible. The purpose of the study is to compare groups of patients who either receive therapy after CAR T-cells and patients that do not receive further therapy after CAR T-cells.
