What this trial studies

This observational study assesses the immune responses to vaccines in patients with multiple myeloma and non-Hodgkin lymphoma who have undergone CAR-T therapy. It aims to determine whether CAR-T treatment affects the effectiveness of vaccines against various diseases, including measles, mumps, and rubella. The study will measure antibody titers before and after CAR-T therapy and evaluate changes in antibody levels in relation to vaccination and immune cell counts. Blood samples will be collected, and medical records will be reviewed throughout the study.

Who should consider this trial

Good fit: Ideal candidates include adults aged 18 and older with a confirmed diagnosis of multiple myeloma or specific types of non-Hodgkin lymphoma who are preparing for CAR-T therapy.

Not a fit: Patients currently using immunosuppressive agents or those with uncontrolled infections may not benefit from this study.

Why it matters

Potential benefit: If successful, this study could help optimize vaccination strategies for patients undergoing CAR-T therapy, improving their overall immune protection.

How similar studies have performed: While this approach is relatively novel, similar studies assessing vaccine responses in immunocompromised populations have shown varying degrees of success.
