Italian Observational Study on CAR-T Therapy for Lymphoma (CART-SIE)

March 24, 2024 updated by: Paolo Corradini

A Multicenter Prospective Observational Study on Chimeric Antigen Receptor (CAR) T-cell Therapy for Lymphoma: Monitoring Feasibility, Efficacy, Toxicity and Biomarkers in a Real Life Setting

The goal of this observational study on chimeric antigen receptor T-cell therapy is to monitor the feasibility, efficacy, toxicity and biomarkers in a real life setting.

Partecipants will be asked to agree to their clinical data collection and to partecipate to the optional biological study that aims to evaluate biomarkers of toxicity and response (clinical characteristics, cytokine profile, cellcomposition and type of the CAR-T cell product, lymphoma genomics). The study will evaluate even the disease response according to lugano criteria by PET and CT in routine clinical activity.

Study Overview

Detailed Description

This observational prosopective multicenter study aims to:

  1. evaluate the feasibility of CAR T-cell treatment in the real-life setting, with particular regard to eligible patients versus those subjected to leukapheresis versus those finally treated.
  2. evaluate the survival outcome of PMBCL, DLBCL, MCL and FL patients treated with CAR T-cells versus those potentially eligible, but excluded from cellular therapy for other causes (either related to the patient or to the manufacturing);
  3. monitor the incidence of early and late AEs up to three year after CAR-T;
  4. evaluate disease response and immune recovery biomarkers at different time-points up after CAR-T (when clinically indicated or using blood sampling leftover);
  5. evaluate biomarkers of toxicity and response (clinical characteristics, cytokine profile, cell composition and type of the CAR T-cell product, lymphoma genomics).
  6. evaluate disease response according to Lugano criteria by PET and CT in routine clinical activity.

Primary Objective:

• Feasibility and efficacy of the treatment in the real life practice

Secondary Objectives:

  • Evaluation of Outcome [Response rate (ORR), Overall survival (OS), Progression free survival (PFS), duration of response (DoR) non-relapse mortality (NRM)] according to Lugano criteria.
  • Evaluation of safety (CRS, neurotoxicity, infections, cytopenias, B cell aplasia, second malignancies) with particular attention to the safety in the new indications
  • Evaluation of bridging therapy (outcome and safety)
  • Evaluation of salvage therapy after CAR-T failure (outcome and safety)
  • Comparison of the different CAR T-cell products (time from patient screening to infusion, disease response and safety)
  • Comparison of the different histotypes (PMBCL, DLBCL, MCL FL) according to CAR-T cell products

The screening will be done according to the axi-cel, tisagen-cel, brexucabtagene autoleucel and lisocabtagene maraleucel label criteria, the eligibility of a given patient to CAR-T will be definedaccording to AIFA criteria.

All patients eligible to CAR-T will be consecutively enrolled Biological samples will be stored at each institution or centralized at the Fondazione IRCCS Istituto Nazionale dei Tumori, Milano. Fondazione Italiana Linfomi (FIL) will be in charge of the GCP management of the study. Web-based CRF are prepared by FIL.

Time Frame: 10 years enrollment, minimum 1 year follow-up
Evaluate the feasibility of CAR T-cell treatment in the real-life setting, with particular regard to eligible patients versus those subjected to leukapheresis versus those finally treated. The percentage of patients infused will be estimated as the number of patients infused divided by the total number of those declared eligible; the corresponding exact confidence intervals at 95% will also be estimated.

Other Outcome Measures

Outcome Measure
Measure Description
Time Frame
Characterization of biomarkers of early response (circulating tumor cell free DNA versus PET and CT scans)
Time Frame: 10 years, minimum f-up 1 year
To study the circulating cell free DNA modulation during time, besides descriptive statistical analyses, we will use non parametric factorial models for longitudinal data [Brunner E, Domhof S, Langer F. Nonparametric analysis of longitudinal data in factorial experiments. John Wiley & Sons 2002, New York]. Such models were chosen because they allow take into account measurement incompleteness and positive asymmetry of biomarker distribution, and because they are robust to outliers. The models also allow to test the difference in the longitudinal profiles according to specific covariates.
