Trial summary

This study evaluates immune responses after CAR-T therapy to find out if CAR-T therapy reduces the effectiveness of the vaccines (vaccine immunity) against diseases such as measles, mumps and rubella, among others in patients with multiple myeloma and non-Hodgkin lymphoma.

About this study

Official title: Vaccine Responses in Patient With Multiple Myeloma and Non-Hodgkins Lymphoma Post CAR-T Treatment

This study evaluates immune responses after CAR-T therapy to find out if CAR-T therapy reduces the effectiveness of the vaccines (vaccine immunity) against diseases such as measles, mumps and rubella, among others in patients with multiple myeloma and non-Hodgkin lymphoma.

Read the detailed description

PRIMARY OBJECTIVES:

  1. To assess positive VPD antibody (Ab) titers prior to and at 6 months after CAR-T therapy to evaluate the impact of CAR-T on immune responses in patients undergoing CAR-T therapy.

II. To assess the change in Ab titer to S. pneumoniae and tetanus at 6 months and 1 year post-vaccination and evaluate if titer increases are correlated to post-vaccination CD4+ count and IgG level.

OUTLINE: This is an observational study.

Patients may receive up to 3 doses of pneumococcal and/or tetanus vaccine per institutional policy of revaccination. Patients undergo blood sample collection and have medical records reviewed throughout the study.

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. Preserved immunity

    Will be defined as titers that meet the definition of positive both pre- and post-CAR-T cell infusion. The proportion of subjects who have preserved immunity to each VPD will be estimated with an exact 95% confidence interval.

    Measured: Up to 12 months after CAR-T cell infusion

Secondary outcomes (1)
  1. Change in antibody titers

    Immune reconstitution will be reported based on ELISA assays for S. pneumoniae or tetanus after each dose of respective vaccine for the re-vaccination populations. Will be correlated with the changes of CD4+ and IgG using a Spearman correlation coefficient.

    Measured: At baseline, at 6 months and at 1 year after vaccination

Questions about this trial

What is this clinical trial studying?

An observational study of Chronic Lymphocytic Leukemia and Diffuse Large B-Cell Lymphoma, run by OHSU Knight Cancer Institute at 1 site in United States.

The full registered description is in the About this study section and the official record.

Who may be eligible to take part?

The sponsor lists 6 inclusion and 2 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.

Is this clinical trial currently recruiting?

The record says: looking for participants now, as of the sponsor's last update on 23 Sep 2026. Status can change between updates, so confirm with the study contact before making plans.

Where is the study taking place?

The record lists 1 site in United States. Whether a site is taking part right now should be confirmed with that site. See every site.

What are the possible benefits and risks?

They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.

Are results available for this study?

This study is still under way. Results are not available in the source record yet.

How can a doctor refer a patient or contact the research team?

Each site lists its own contact: choose the nearest one under Trial locations. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Preserved immunity (time frame: Up to 12 months after CAR-T cell infusion). It is what the study was designed to measure, not a finding.

Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?

No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.

How often is this information updated?

AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 23 Sep 2026.
