Official title

Rabies Vaccination to Assess Vaccine Responsiveness After B Cell Targeted CAR-T Cell Therapies

Brief summary

Reproduced verbatim from the official ClinicalTrials.gov record. Not medical advice.

This phase I trial will use the inactivated rabies virus vaccine to assess immune function in patients who previously underwent B cell targeted chimeric antigen receptor-modified T cell immunotherapy (CARTx). A cohort of healthy volunteers will also be enrolled as a comparator group. CARTx is a new treatment for patients with B-cell malignancies (cancer of the B-cells), and the long-term effects of CARTx on immune function are not yet well understood. Learning more about vaccine responsiveness in patients who previously underwent CARTx may help doctors better understand immune function. The findings will guide evidence-based strategies for infection prevention to improve outcomes in this rapidly growing population of high-risk individuals.
