Long-term Follow-up Study of Patients Receiving CAR-T Cells

November 6, 2025 updated by: Nirav Shah, Medical College of Wisconsin

This protocol is designed as a long-term follow-up study of participants who will receive CAR-T cells as part of a clinical trial at the Medical College of Wisconsin/ Froedtert Hospital. The clinical trials include the following:

Phase 1 Study of CAR-20/19-T Cells in Patients with Relapsed Refractory B Cell Malignancies (NCT03019055); Phase I Trial of BCMA-TGF-BETA CAR-T Cells in Relapsed, Refractory Myeloma (NCT05976555); CAR20.19.22 T-cells in Relapsed, Refractory B-cell Malignancies (NCT05094206); LV20.19 CAR T-Cells in Combination With Pirtobrutinib for Relapsed, Refractory B-cell Malignancies (NCT05990465); CAR-20/19-T Cells in Patients With Relapsed Refractory B Cell Malignancies (NCT04186520)

Cohorts and Interventions

Group / Cohort
Intervention / Treatment
Participants who received CAR-T cells.
Participants who received CAR-T cells at Froedtert Hospital & the Medical College of Wisconsin in clinical trials (e.g., NCT05976555, NCT05094206, NCT05990465, NCT03019055 or NCT04186520).
Other: Long-Term Follow-Up of Participants who Received CAR-T cells
No study drug is administered in this study. Participants who received CAR-T cells in a previous trial will be evaluated in this trial for long-term safety and efficacy.
