Treatment with CAR T cells for high-risk neuroblastoma in children

A Phase 1/2 Study of hALK.CAR T Cells for Patients With Relapsed/Refractory High-risk Neuroblastoma

Phase1; Phase2 Interventional Boston Children's Hospital · NCT06803875

This study is testing a new CAR T cell treatment for children with hard-to-treat neuroblastoma to see if it is safe and how well it works.

What this trial studies

This Phase 1/2 trial evaluates the safety and feasibility of using autologous chimeric antigen receptor (CAR) T cells that target the human Anaplastic Lymphoma Kinase (ALK) receptor in pediatric patients with relapsed or refractory high-risk neuroblastoma. The study is divided into two phases: Phase 1 focuses on determining the maximum tolerated dose (MTD) of the CAR T cells, while Phase 2 aims to assess the response rates to this treatment. Participants must have histologically verified neuroblastoma and meet specific eligibility criteria related to age, disease status, and organ function.

Who should consider this trial

Good fit: Ideal candidates are pediatric patients aged 12 months to 30 years with relapsed or refractory high-risk neuroblastoma.

Not a fit: Patients who are pregnant or have not achieved adequate organ function may not benefit from this study.

Why it matters

Potential benefit: If successful, this treatment could provide a new therapeutic option for children with high-risk neuroblastoma who have exhausted standard treatment options.

How similar studies have performed: Other studies utilizing CAR T cell therapy have shown promising results in various cancers, suggesting potential success for this novel approach in neuroblastoma.

   2. Patients must have high-risk neuroblastoma according to Children's Oncology Group (COG) risk classification at time of study enrollment
   3. Patients must have persistent/refractory or relapsed disease for which standard curative measures are no longer effective, as defined in the protocol
   4. Patients must have evaluable or measurable disease per the revised International Neuroblastoma Response Criteria (INRC)
3. Adequate washout from prior treatment regimens
4. Adequate organ function

6. Uncontrolled CNS metastasis
7. CNS disorder such as cerebrovascular ischemia/hemorrhage, dementia, cerebellar disease, or autoimmune disease with CNS involvement which may impair the ability to evaluate neurotoxicity
