A Phase 3 interventional study of CTL019 in B-cell Acute Lymphoblastic Leukemia and Diffuse Large B-cell Lymphoma, sponsored by Novartis Pharmaceuticals. Recruiting at 55 sites in 2 countries. Open to participants aged 0 Years to 100 Years. Per ClinicalTrials.gov, last updated 2026-09-15.
Sponsored by Novartis Pharmaceuticals (part of Novartis) · Phase 3, Interventional, and Treatment
This study will evaluate the safety of tisagenlecleucel that is out of specification( OOS) for release as commercial product. Specifically, this study will evaluate the safety of CTL019 in the patients treated within the approved label by Japan Health Authority in Part 2. Only for Part 1, in addition to safety, key efficacy of CTL019 will also be evaluated.
This is a single-arm, open-label, multicenter, interventional Phase IIIb study in pediatric/young adult patients with relapsed/refractory (r/r) B-cell acute lymphoblastic leukemia (pALL) and adult patients with r/r large B-cell lymphoma (LBCL) including diffuse large B-cell lymphoma (DLBCL) not otherwise specified, high-grade B cell lymphoma, and DLBCL arising from follicular lymphoma for Part 1 and and r/r ALL and r/r non-Hodgkin's lymphomas (NHL) for Part 2
Patients whose final manufactured tisagenlecleucel patient-specific batch does not meet the approved local commercial release specifications are eligible for inclusion. Each case will be individually assessed and approved by the Novartis manufacturing facility and the Novartis global medical team (including Patient Safety). Following a single infusion of CTL019, the patient will be followed for 3 months for Part 1, and 1 day for Part 2.

Key exclusion criteria:
For part 1, patients meeting any of the following criteria are not eligible for inclusion in this study:
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.
The human immunodeficiency virus, which weakens the immune system.
Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.
Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.
Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.
Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.
After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.
An allergy, or another reaction of the immune system, to a substance. “Hypersensitivity to the study drug” means a known allergic reaction to it — not every side effect a medicine can have.

Pediatric/young adult patients with r/r pALL who meet the indication in the Health Authority-approved CTL019 package insert in the respective country/region whose final manufactured product is OOS for commercial release, but it is considered that the benefit-risk profile may remain favorable and the usual expected benefits of infusing such a product outweigh the potential risks for the patient.

Started Nov 2019 (actual). Primary completion is estimated for Mar 2027, 88 months after the start.
Of 19 phase 3 interventional studies under Burkitt Lymphoma, half reached primary completion within 106 months of starting (the median), counting those still running; a quarter within 78 and three quarters within 119. This study's planned 88 months is below that.
