Capizzi Escalating Methotrexate Versus High Dose Methotrexate in Children With Newly Diagnosed T-cell Lymphoblastic Lymphoma (T-LBL)
A Randomized Trial Using a Modified COG ABFM Regimen Backbone to Investigate Capizzi Escalating Methotrexate Versus High Dose Methotrexate in Children With Newly Diagnosed T-cell Lymphoblastic Lymphoma (T-LBL)
Capizzi Escalating Methotrexate Versus High Dose Methotrexate in Children With Newly Diagnosed T-cell Lymphoblastic Lymphoma (T-LBL) (NCT05681260) is a Phase 3 interventional studying T-cell Lymphoblastic Lymphoma, sponsored by Children's Cancer Group, China. RECRUITING as of the most recent ClinicalTrials.gov update. Talk to your doctor before contacting the trial site.
About This Trial
T-cell lymphoblastic lymphoma (T-LBL) is the second most common subtype of non-Hodgkin lymphoma (NHL) in children and adolescents. With current treatment, event-free survival (EFS) rates vary between 75%\~85%. Two different MTX intensification strategies are used commonly: HD-MTX with leucovorin rescue, and Capizzi-style MTX without leucovorin rescue plus PEG-ASP (C-MTX). Although superior outcome of patients with T-ALL receiving C-MTX compared with HD-MTX on the AALL0434 trial, the 2 approaches had not been compared directly in patients with T-LBL. There remains controversy on PET/CT interpretation in children with NHL. Large prospective studies in pediatric patients with T-LBL regarding PET/CT value for this is scarce. Around 1% pediatric patients with T-LBL will not achieve remission at the end of Induction (induction failure). The optimal treatment for this small subgroup is largely unclear. The BFM HR Blocks usually are applied to these patients even though the efficacy is unknown. Novel targeted therapies are needed for use. Dasatinib is identified as a targeted therapy for T-cell ALL in preclinical drug screening.
What Stage of Research Is This?
Phase 3 trials confirm efficacy and safety in large patient groups (often 300–3,000+) and form the evidence base for an FDA approval submission. For T-cell Lymphoblastic Lymphoma, Phase 3 studies typically randomize participants between the investigational treatment and either a placebo or current standard of care. A successful Phase 3 result is the threshold most treatments need to clear before regulatory approval.
This trial is currently recruiting participants. The sponsor has registered the study with ClinicalTrials.gov as actively enrolling, which means new applicants who meet the eligibility criteria can be considered for screening. Trial status can change between updates — confirm current recruiting status with the study contact before traveling for a screening visit.
Target enrollment of 200 participants puts this in the typical range for a Phase 2-style efficacy study or a moderate Phase 3 trial in a focused T-cell Lymphoblastic Lymphoma subpopulation. At this scale, the study has enough statistical power to detect a clear treatment effect but is not the largest cohort in the field.

How to Talk to Your Doctor About This Trial
Bring the printable summary of this trial — including the NCT ID (NCT05681260), the sponsor (Children's Cancer Group, China), and the key eligibility criteria — to your next appointment. Your doctor can review the inclusion and exclusion criteria against your medical history, lab values, and current treatments to assess whether you are likely to qualify. They can also help you weigh whether trial participation makes sense alongside your existing care plan.
Useful questions to walk through together: What does the trial protocol require beyond standard care? How long is the active treatment phase, and how long is follow-up? Are there study visits at sites I can reach? Who pays for the trial-specific procedures, and who pays for standard-of-care portions?

Who can participate in NCT05681260?
Eligibility for this trial depends on the specific inclusion and exclusion criteria set by the sponsor. The plain-English summary above translates the most important criteria into accessible language; the official clinical text is preserved in the collapsible section underneath. Whether you fit any specific trial is a medical decision your doctor needs to confirm — bring the trial information to your treating physician for a full review against your medical history.
How do I contact the trial site for NCT05681260?
Contact information registered with ClinicalTrials.gov is shown in the sidebar of this page. Before reaching out, confirm with your treating physician that this trial is appropriate for your situation. The trial site will then walk you through the screening process to determine final eligibility.
Is participating in a clinical trial safe?
Clinical trials in the United States are regulated by the FDA and overseen by Institutional Review Boards (IRBs) that review the protocol for safety. Risk varies by trial — Phase 1 studies test new treatments in humans for the first time, while Phase 3 trials use treatments that have already passed earlier safety screening. The informed consent document for any specific trial details the known risks and what to expect. Discuss those risks with your physician before deciding whether to participate.
