About this study

Official title: Prediction of Response Related to IMmune Age T Cell Fitness in Elderly Patients With Relapsed and Refractory Multiple Myeloma

Relapsed/refractory multiple myeloma (RRMM) predominantly affects older adults, who exhibit marked heterogeneity in treatment outcomes despite receiving the same therapies. Clinical frailty scores, such as the International Myeloma Working Group (IMWG) Frailty Index, predict survival and treatment tolerance but provide limited information on immune competence, a key determinant of response to T-cell-based immunotherapies.

The PRIME study is a prospective, multicenter, non-interventional exploratory study designed to evaluate the relationship between immune fitness and clinical outcomes in patients aged 65 years or older with RRMM treated with standard-of-care chimeric antigen receptor T-cell (CAR-T) therapy or bispecific antibodies. Peripheral blood samples collected before treatment initiation will be analyzed to characterize T-cell differentiation, activation, senescence, exhaustion, and T-helper cell subsets using multiparametric immunophenotyping. Serum biomarkers, including soluble B-cell maturation antigen (sBCMA) and senescence-associated soluble markers, will also be assessed.

  • The primary objective is to determine whether baseline immune profiles are associated with quality of response at 3 months after treatment initiation.
  • Secondary objectives include evaluating the association between immune profiles and treatment-related toxicities, including cytokine release syndrome (CRS), immune effector cell-associated neurotoxicity syndrome (ICANS), other neurological toxicities, and infectious complications. Exploratory analyses will integrate immune, geriatric, sarcopenia, and clinical variables using statistical approaches to identify novel predictors of efficacy, survival, and toxicity.

By combining immune phenotyping with frailty assessment, the PRIME study aims to improve biological risk stratification and support the development of more personalized treatment strategies for older patients with multiple myeloma.

Read the detailed description

The PRIME study is a prospective, multicenter, non-interventional exploratory study investigating immune fitness in patients aged 65 years or older with relapsed or refractory multiple myeloma treated with standard-of-care CAR-T cell therapy or bispecific antibodies.

The study is based on the hypothesis that chronological age and clinical frailty do not fully explain the variability in efficacy and toxicity observed with T-cell-directed immunotherapies. Baseline peripheral blood samples will be collected before treatment initiation for comprehensive immune profiling using multiparametric flow cytometry. The analysis will characterize T-cell differentiation, activation, senescence, exhaustion, regulatory T cells, and T-helper cell subsets through the evaluation of markers including CD3, CD4, CD8, CD25, CD27, CD28, CD38, CD45, CD45RO, CD57, CD127, KLRG1, PD-1, TIM-3, LAG-3, TIGIT, CCR4, CCR6, and CXCR3. Serum samples will also be collected to measure soluble B-cell maturation antigen (sBCMA) and senescence-associated soluble biomarkers.

Participants will be followed according to routine clinical practice. Clinical data collected during follow-up will include disease characteristics, geriatric assessment, sarcopenia assessment, treatment response, and treatment-related toxicities. The primary objective is to evaluate the association between baseline immune fitness and treatment response at 3 months. Secondary analyses will investigate the relationship between immune profiles and adverse events, geriatric status, and sarcopenia. The results are expected to improve understanding of the biological determinants of response and toxicity to T-cell-directed immunotherapies and to support improved risk stratification in older patients with relapsed or refractory multiple myeloma.

The record lists 3 sites in Belgium. 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?

Contact Marie Vercruyssen, MD (+32497840746, marie.vercruyssen@hubruxelles.be), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Rate of ≥VGPR or better according to IMWG criteria at 3 months. (time frame: 3 months after the treatment). It is what the study was designed to measure, not a finding.

Where can I read the original study information?

On the ClinicalTrials.gov record for NCT07674498, which also lists 14 linked publications.

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 29 Jun 2026.
