Understanding blood cell issues after CAR-T therapy for multiple myeloma or lymphoproliferative disorders

MC230818 Understanding the Mechanisms of Clonal and Non-Clonal Cytopenia Following CAR-T Therapy

NA · Mayo Clinic · NCT06630104

This study is testing how certain genetic differences in people with multiple myeloma or lymphoproliferative disorders affect their chances of developing low blood cell counts after CAR-T therapy.

What this trial studies

This clinical trial investigates how genetic variations in patients with multiple myeloma or CD19 positive lymphoproliferative disorder affect the risk of developing cytopenia after receiving CAR-T therapy. The study involves collecting bone marrow, hair, buccal, and saliva samples to analyze preexisting and therapy-emergent genetic variants. Patients will be monitored for cytopenia and undergo follow-up assessments for up to two years to evaluate the impact of these genetic factors. The goal is to identify gene mutations that may help predict the risk of prolonged cytopenia following treatment.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with confirmed multiple myeloma or CD19 positive lymphoproliferative disorder who are eligible for CAR-T therapy.

Not a fit: Patients who are ineligible for CAR-T therapy or have a prior diagnosis of myeloid neoplasm may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could lead to better risk assessment and management strategies for patients undergoing CAR-T therapy.

How similar studies have performed: While this approach is novel in its focus on genetic variants related to cytopenia post-CAR-T therapy, similar studies have shown promise in understanding genetic influences on treatment outcomes.
