Validating DW-MRI and Fat Fraction in Multiple Myeloma Post-ASCT: The RAC-FAT Study"
2026年9月7日 更新者:Fondazione EMN Italy Onlus
Multicenter Observational Study for the Validation of the Predictive Role of Diffusion-Weighted Whole-body MRI (DW-MRI) Imaging Response According to MY-RADS Criteria (RAC Score) and Fat Fraction (rFF%) After Autologous Stem Cell Transplantation in Multiple Myeloma Patients Treated With First-Line Anti-CD38-Based Therapy (RAC-FAT Study)
This is a multicenter, observational, retrospective-prospective study designed to validate the predictive role of advanced imaging in patients with newly diagnosed multiple myeloma (NDMM).
The main purpose of this study is to estimate the prevalence of radiological response categories (Response Assessment Category, RAC score) and evaluate the predictive value of relative Fat Fraction (rFF%) using Diffusion-Weighted Whole-Body Magnetic Resonance Imaging (DW-MRI) in patients who have undergone autologous stem cell transplantation (ASCT) after receiving first-line anti-CD38-based quadruplet induction therapy.

详细说明
The role of functional imaging in Multiple Myeloma (MM) has become essential for assessing treatment response.
This study focuses on the Myeloma Response Assessment and Diagnosis System (MY-RADS) guidelines and the quantitative parameter of rFF% to identify "functional high-risk" patients who may experience early relapse despite achieving conventional deep responses.The study will involve two cohorts:Retrospective Cohort: Includes patients treated since January 1st, 2020, with available post-ASCT DW-MRI data performed during routine clinical practice.Prospective Cohort: Includes newly diagnosed patients enrolled after their standard-of-care ASCT and post-transplant DW-MRI assessment.Participants will not receive any investigational or trial-specific treatment.
All diagnostic and therapeutic procedures follow the current standard of care.
Data regarding clinical characteristics, treatment details (induction, ASCT, maintenance), DW-MRI parameters (RAC score, apparent diffusion coefficient [ADC], and rFF% values), and minimal residual disease (MRD) will be collected and recorded in an anonymized electronic Case Report Form (eCRF).The study aims to enroll a minimum of 92 participants to evaluate:Primary Endpoint: Prevalence of RAC1 and RAC≥2 categories post-ASCT.Secondary Endpoints: Progression-free survival (PFS) and Overall Survival (OS) stratified by RAC score and rFF%, and the concordance between imaging results and bone marrow MRD.

Observational: MM Patient Cohort
This cohort includes transplant-eligible patients with newly diagnosed multiple myeloma (NDMM) who have completed first-line anti-CD38-based quadruplet induction therapy and autologous stem cell transplantation (ASCT).
|
Collection and analysis of Diffusion-Weighted Whole-body MRI data performed post-ASCT.
The radiological response is evaluated using the Response Assessment Category (RAC) score (1 to 5) according to MY-RADS criteria.
Quantitative assessment of the relative Fat Fraction (percentage of fat within skeletal regions) measured on residual focal lesions after transplantation to identify functional high-risk (FHR) patients.
Retrospective and prospective collection of clinical outcomes, including Progression-Free Survival (PFS), Overall Survival (OS), and Minimal Residual Disease (MRD) status from medical records.
