An observational study in Diffuse Large B-cell Lymphoma, Acute Lymphoblastic Leukemia and Follicular Lymphoma, sponsored by Novartis Pharmaceuticals. Recruiting at 7 sites in Brazil. Open to participants aged 0 Years to 100 Years. Per ClinicalTrials.gov, last updated 2026-11-10.
Sponsored by Novartis Pharmaceuticals (part of Novartis) · Observational
This will be a multicenter, national, non-interventional, prospective cohort study
Eligible participants will be pediatric (\<18 years) and adult patients (aged 18 years or older) with B-cell malignancies who have received tisagenlecleucel through the commercial setting or out-of-specification (OOS) use in Brazil. We will collect data prospectively and complement missing information with retrospective data collection, when necessary. It is anticipated that approximately 200 patients will be enrolled in the cohort over 5 years divided among the study indications.
Since this is a non-interventional study, no administration of study drug or application of questionnaires will be mandated by this protocol. The study will consist of a "Pre-infusion" and a "Post infusion follow-up period" for up to 15 years post tisagenlecleucel infusion. All patients will be followed until death or last scheduled visit, whichever comes first.
For the study, "pre-infusion" and "follow-up post infusion" phases are defined as:
1,868 studies on the registry are indexed under Lymphoma, Large B-Cell, Diffuse; 355 are open to participants now.
This study's planned enrollment of 200 is above the median of 150 across 185 observational studies indexed under Lymphoma, Large B-Cell, Diffuse.

The study population will include pediatric/ adult patients with relapsed/refractory B-cell acute lymphoblastic leukemia aged 0-25 years and adult patients aged ≥ 18 years with relapsed/refractory Diffuse Large B-cell Lymphoma and relapsed/refractory follicular lymphoma, who received tisagenlecleucel infusion in the commercial setting or out-of-specification.

Exclusion Criteria:
Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.

Overall response rate (ORR)
The overall response rate will be defined as the total proportion of participants exhibiting either the best overall response (BOR) of complete or partial responses and the proportion of patient with BOR of CR/PR or CR/CRi for ALL patients will be reported along with its 95% CI. For ALL participants, the BOR will be defined as a CR or a CRi in accordance with National Comprehensive Cancer Network (NCCN) guidelines and previous guidelines (Appelbaum et al 2007)(Cheson et al 2003). For lymphomas, the BOR will be defined as a CR or PR in accordance with the Cheson response criteria (Cheson et al 2007) and the Lugano classification (Cheson et al 2016).
Time frame: Up to 15 years
MRD negative overall response rate
The percentage of B-cell ALL patients who achieve a Best Overall Response (BOR) of CR or CRi with a Minimal residual disease (MRD) negative bone marrow will be provided with 95% CI.
Time frame: Up to 15 years
Duration of overall response (DOR)
Duration of overall response (DOR) applies only to patients whose best overall disease response was either: * CR or PR for patients with lymphomas, or * CR or a CRi for patients with ALL. DOR will be defined as the time from the date of first documented disease response (Complete Response (CR) or PR for patients with lymphomas, and Complete Remission (CR) or CRi for patients with ALL), whichever occurs first, to the date of first documented progression or first documented relapse according to indication, or to the date of death due to the underlying disease. In case a patient does not have progression/relapse or death due to underlying disease (defined as the event for this outcome) prior to data cut-off, DOR will be censored at the date of the last assessment on or prior to the earliest censoring event.
Time frame: Up to 15 years
Relapse-free survival (RFS)
RFS is measured by the time from date of first documented disease response as CR or CRi to relapse or death due to any cause in ALL patients. In case a patient does not have relapse or death due to any cause prior to data cutoff, RFS will be censored at the date of the last adequate assessment on or prior to the earliest censoring event.
Time frame: Up to 15 years
Event-free survival (EFS) for ALL patients
EFS is the time from date of first tisagenlecleucel infusion to treatment failure, relapse or death from any cause, whichever occurred first, for B-cell ALL patients.
Time frame: Up to 15 years
Progression free survival (PFS) for DLBCL patients
PFS is defined as the time from the date of first infusion to the date of event defined as the first documented progression of lymphoma or death due to any cause. If a patient has not had an event, progression-free survival is censored at the date of the last adequate assessment. In case a patient does not have progression or death prior to data cutoff, PFS will be censored at the date of the last adequate assessment on or prior to the earliest censoring event.
Time frame: Up to 15 years
Overall survival (OS)
Overall survival is the time from date of first tisagenlecleucel infusion to the date of death due to any reason, In case a patient is alive at the date of last contact on or before data cutoff, OS is censored at the date of last contact.
Time frame: Up to 15 years
Number of ALL patients with hematologic recovery
Dates of hematological recovery (i.e., dates of Absolute Neutrophil Count (ANC) and platelet recovery) will be collected. ANC recovery is defined as an ANC of ≥ 0.5 × 109/L (500/mm\^3) for 3 consecutive laboratory values obtained on different days. Date of ANC recovery is the date of the first of 3 consecutive laboratory values where the ANC is ≥ 0.5 × 109/L (CIBMTR). The first date of the 3 consecutive laboratory values obtained on different days where the platelet count was ≥ 20 × 109/L should be recorded. It should be ensured that no platelet transfusions were administered for 7 days immediately preceding this date (CIBMTR).
Time frame: Up to 15 years

The type and frequency of SAEs and AE of special interest (including secondary malignancies) will be collected

Which establishes the Immune effector Cell-associated Encephalopathy (ICE Score) for adults/ adolescents and Cornell Assessment of Pediatric Delirium (CAPD) for pediatric patients under 12 years
