About this study
This clinical trial evaluates the impact of preexisting and therapy-emergent germline and somatic variants on cytopenia in patients with multiple myeloma or CD19 positive lymphoproliferative disorder (LPD) following chimeric antigen receptor T-cell (CAR-T) therapy. The most common adverse event after CAR-T therapy is lower than normal blood cells (cytopenia) and up to one third of patients experience cytopenia that last longer than 30 days post-infusion. Germline and somatic variants are changes in genes found using cancer genomic tests. Cancer genetic/genomic testing is a series of tests that find specific changes in cancer cells or in blood deoxyribonucleic acid. Identifying gene mutations may help identify the risk of cytopenia in patients with multiple myeloma or CD19 positive LPD following CAR-T therapy.
