Vaccine Response After CAR-T Therapy for B-Cell Lymphoma
Trial Summary
What is the purpose of this trial?
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.
Will I have to stop taking my current medications?
The trial does not specify if you need to stop taking your current medications. However, if you are taking corticosteroids at a dose higher than 0.5 mg/kg/day, you may not be eligible to participate.
What data supports the effectiveness of the treatment Wistar Rabies Virus Strain PM-1503-3M Vaccine for B-Cell Lymphoma?
Research on therapeutic vaccines for lymphomas shows that vaccines can induce immune responses capable of targeting and potentially eradicating lymphoma cells. Although some clinical trials have not shown prolonged survival, there are observations suggesting clinical efficacy, and ongoing efforts aim to improve vaccine strategies.12345
Is the rabies vaccine safe for humans?
The rabies vaccine has been tested in various studies and is generally considered safe for humans. Most side effects are mild, such as pain at the injection site, headache, and muscle aches. Serious reactions are rare, and no vaccine-related serious adverse reactions were reported in the studies.678910
How does the treatment for B-cell lymphoma differ from other treatments?
This treatment uses CAR-T cell therapy, which involves modifying a patient's own T cells to target specific proteins on cancer cells, making it a personalized and targeted approach. Unlike traditional treatments, it can be tailored to target multiple antigens, such as CD19 and CD20, potentially reducing the risk of cancer relapse due to antigen loss.1112131415

Eligibility Criteria
This trial is for adults who've had B-cell targeted CAR-T cell therapy and been relapse-free for at least 6 months. It's also open to healthy adults as a comparison group. Participants must understand the study and consent in writing. Exclusions include pregnancy, breastfeeding, prior rabies vaccines, severe vaccine reactions, certain medication use, active infections, known allergies to vaccine components or medical attention-requiring reactions to any vaccine.Inclusion Criteria
