A Study of Voice as a Way to Monitor for Side Effects in People Receiving CAR T-Cell Therapy

The purpose of this study is to collect voice recordings and nervous system (neurologic) assessments from people with non-Hodgkin lymphoma (NHL) or multiple myeloma (MM) who are receiving standard treatment with CAR T-cell therapy. Researchers will study whether these voice recordings and assessments are a practical (feasible) way to monitor for immune effector cell-associated neurotoxicity syndrome (ICANS). Feasibility will be measured by tracking how many participants join the study and complete the assessments.
