No investigator recorded in the registry for this trial

These describe the registry record only, and today we hold ClinicalTrials.gov data. Absent fields lower a score, and absence often reflects registration practice rather than study quality. A high-stature trial is not necessarily safer or a better choice for you — enrolling in a large definitive trial can mean a higher chance of receiving placebo, while a small early-phase study may be the only route to a new therapy.

Résumé

This phase III trial tests how well the addition of dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy works for treating children with newly diagnosed high-risk neuroblastoma. Dinutuximab is a monoclonal antibody that binds to a molecule called GD2, which is found on the surface of neuroblastoma cells, but is not present on many healthy or normal cells in the body. When dinutuximab binds to the neuroblastoma cells, it helps signal the immune system to kill the tumor cells. This helps the cells of the immune system kill the cancer cells, this is a type of immunotherapy. When chemotherapy and immunotherapy are given together, during the same treatment cycle, it is called chemoimmunotherapy. This clinical trial randomly assigns patients to receive either standard chemotherapy and surgery or chemoimmunotherapy (chemotherapy plus dinutuximab) and surgery during Induction therapy. Chemotherapy drugs administered during Induction include, cyclophosphamide, topotecan, cisplatin, etoposide, vincristine, and doxorubicin. These drugs work in different ways to stop the growth of cancer cells, either by killing the cells, by stopping them from dividing or by stopping them from spreading. Upon completion of 5 cycles of Induction therapy, a disease evaluation is completed to determine how well the treatment worked. If the tumor responds to therapy, patients receive a tandem transplantation with stem cell rescue. If the tumor has little improvement or worsens, patients receive chemoimmunotherapy on Extended Induction. During Extended Induction, dinutuximab is given with irinotecan, temozolomide. Patients with a good response to therapy move on to Consolidation therapy, when very high doses of chemotherapy are given at two separate points to kill any remaining cancer cells. Following, transplant, radiation therapy is given to the site where the cancer originated (primary site) and to any other areas that are still active at the end of Induction. The final stage of therapy is Post-Consolidation. During Post-Consolidation, dinutuximab is given with isotretinoin, with the goal of maintaining the response achieved with the previous therapy. Adding dinutuximab to Induction chemotherapy along with standard of care surgical resection of the primary tumor, radiation, stem cell transplantation, and immunotherapy may be better at treating children with newly diagnosed high-risk neuroblastoma.

PRIMARY OBJECTIVE: I. To determine if the event-free survival (EFS) of patients with newly diagnosed high-risk neuroblastoma assigned to early chemoimmunotherapy during Induction differs from that of patients who are not assigned to treatment that includes early chemoimmunotherapy. SECONDARY OBJECTIVES: I. To determine if early chemoimmunotherapy during Induction therapy improves end of Induction (EOI) response rates and overall survival (OS) for patients with newly diagnosed high-risk neuroblastoma. II. To determine response rates, EFS, and OS following an Extended Induction regimen with chemoimmunotherapy in patients with progressive disease or a poor response to Induction therapy. III. To compare the toxicities experienced by patients treated with chemoimmunotherapy during Induction versus those experienced by patients treated with standard Induction and to describe toxicities experienced during Extended Induction. IV. To determine GD2 expression on tumor tissue and tumor cells in bone marrow and assess for associations with response and outcome. EXPLORATORY OBJECTIVES: I. To describe the association between tumor and host factors and outcomes in patients receiving protocol therapy. II. To evaluate circulating biomarkers and markers of minimal residual disease at baseline and during therapy, and assess for associations with response and outcome. III. To compare patterns of failure between patients treated with and without dinutuximab during induction. IV. To determine the effect of telomere maintenance mechanisms on end of Induction response rates, EFS, and OS. V. To explore the impact of high-risk neuroblastoma (HRNBL) and its therapy, including the addition of dinutuximab to Induction chemotherapy, on functional and quality of life outcomes in patients with HRNBL, as measured by caregiver (parent/legal guardian) and patient questionnaires. VI. To describe the adequacy of diagnostic biopsy specimens, including those obtained by percutaneous core needle biopsy. VII. To explore the associations between family-reported adverse social determinants of health and both clinical outcomes and biology. VIII. To develop and validate deep learning predictors of Induction response based on diagnostic MIBG scans. (Imaging Objective) IX. To compare institutional versus central determination of overall response, individual response components (primary tumor, soft tissue and bone metastatic disease, and bone marrow metastatic disease), and poor end of induction response (PEIR) and good end of induction response (GEIR) determination. (Imaging Objective) X. To describe late toxicities (including impaired organ function, neuropsychiatric toxicity, and incidence of secondary malignancy) in patients treated with dinutuximab during Induction or Extended Induction to late toxicities in patients who have not received dinutuximab during these phases of therapy. XI. To evaluate whether reduced dose radiotherapy to the primary site clinical target volume (CTV) in patients with complete response of the primary site at EOI results in comparable local control relative to historical cohorts. XII. To compare post-transplant complications between treatment arms, and assess for associations with outcome. XIII. To assess for associations between EOI response (including good end of Induction response \[GEIR\] and poor end of Induction response \[PEIR\]) and individual response components (primary tumor, soft tissue and bone metastatic disease, and bone marrow metastatic disease) with outcome (EFS and OS). XIV. To describe and compare the changes in image-defined risk factors (IDRFs) between patients treated with and without dinutuximab during Induction and associate with surgical outcomes and local failure rates following primary tumor resection. XV. To bank serial samples of blood, bone marrow, and tumor tissue for future research. OUTLINE: Patients receive Induction cycle 1 and are then randomized to 1 of 2 treatment arms. INDUCTION CYCLE 1: Patients receive cyclophosphamide intravenously (IV) over 30 minutes and topotecan IV over 30 minutes on days 1-5 in the absence of unacceptable toxicity. ARM A: INDUCTION CYCLES 2-5: Patients receive cyclophosphamide IV over 30 minutes and topotecan IV over 30 minutes on days 1-5 of cycle 2 in the absence of unacceptable toxicity.

If at any time during Extended Induction testing shows a good tumor response, patients proceed to Consolidation. If after 6 cycles of Extended Induction or if at any time progression is noted, patients are removed from the study. CONSOLIDATION: Patients undergo two autologous hematopoietic stem cell transplantations (HSCTs) during Consolidation. Patients receive thiotepa IV over 2 hours on days -7 to -5 and cyclophosphamide IV over 1 hour on days -5 to -2 during HSCT 1. Patients then receive stem cell infusion IV on day 0.

The impact of TA-TMA occurrence on the timing or exclusion of subsequent therapy and interventions utilized to treat the TA-TMA, and associations with outcomes (EFS and OS) will be assessed.
Délai Up to 100 days post-transplant
Autre critère de jugement
Associations between end of induction (EOI) response and individual response components

Délai Up to 10 years
Autre critère de jugement
Changes in image-defined risk factors (IDRF)
The proportion of patients in the analytic cohort for whom each particular IDRF and also the presence of any IDRF is absent prior to surgical resection will be computed. McNemar's test for paired observations will be applied to determine whether there is a difference in the proportion of each IDRF and any IDRF present before and after initial therapy, and conditional logistic regression will be used to compare between treatment arms A and B. The IDRF status after initial therapy and whether there has been a change from diagnosis will be associated with surgical outcome (complete vs. incomplete resection, presence or absence of surgical complications) using chi-squared tests, and compared between treatment arms A and B with the Cochran-Mantel-Haenszel test. The association of IDRF status with presence or absence of local failure after primary tumor resection will also be evaluated using a chi-squared test, and compared between treatment arms A and B with the Cochran-Mantel-Haenszel.
