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.

Summary

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.

Outcome measures

Primary outcome
Event free survival (EFS)
EFS time is calculated from time of randomization to Arms A or B to first episode of disease relapse or progression, second malignancy, or death, or until last contact if no event has occurred.
Time frame Up to 3 years
Secondary outcome
End of Induction (EOI) response rate
The response rate will be calculated among all evaluable patients at end of Induction. Responders are defined as patients who achieve a \>= partial response per the revised 2017 International Neuroblastoma Response Criteria (INRC)
Time frame From randomization to end of extended Induction, up to 12 months
Secondary outcome
Overall survival (OS)
OS time is calculated from time of randomization to Arms A or B until death, or until last contact if patient is alive.
Time frame Up to 3 years
Secondary outcome
Incidence of adverse events
The proportion of patients with at least one grade 3 or higher non-hematologic toxicity or grade 4 or higher hematologic toxicity during protocol therapy, graded according to the National Cancer Institute Common Terminology Criteria for Adverse Events version 5.0, will be reported.
Time frame Up to 2 years
Secondary outcome
GD2 expression
Dinutuximab binding to pre-therapy patient tumor samples will be measured and categorized as high or low.
Time frame Up to 12 months
Other outcome
Association between tumor and host factors and outcomes
A series of univariate and multivariate Cox proportional hazards (for EFS and OS) and logistic regression (for responders vs. non-responders) models will be fit for patients in Arms A and B to evaluate the relationship between tumor and host factors (including tumor ALK and other somatic mutations, copy-number aberrations, gene fusions, gene expression, and pathogenic germline variants) and chemo-immunotherapy during Induction with outcome.
Time frame Up to 10 years
Other outcome
Circulating biomarkers and markers of minimal residual disease
Will be assessed by comparing the proportion of patients with detectable vs. non-detectable tumor markers (including circulating tumor deoxyribonucleic acid, circulating free DNA, circulating tumor cells, and immune function profiling) between Arms A and B during and after induction and post-consolidation therapy using chi-squared tests at each individual time point, and Cochran's Q across time points to determine if there is a consistent difference in proportions between arms across time. In addition, the tumor markers will be analyzed as continuous variables using longitudinal data analysis methodology such as mixed effects models or generalized estimating equations as appropriate.
Time frame Up to 10 years
Other outcome
Patterns of failure
The impact of early or late chemoimmunotherapy during Induction on the probability of the involvement of a specific disease site at first relapse will be evaluated using Fisher's exact test.
Time frame Up to 10 years
Other outcome
Effect of telomere maintenance mechanisms
A series of univariate and multivariate Cox proportional hazards (for EFS and OS) and logistic regression (for responders vs. non-responders) models will be fit for patients in arms A and B to evaluate the relationship between telomere maintenance mechanism and chemoimmunotherapy during Induction with outcome. Patients will be classified into 3 groups by telomere maintenance mechanism (TMM) based on messenger ribonucleic acid expression of TERT and analysis of telomeric DNA C-circles: telomerase (TERT) positive, alternative of lengthening of telomeres (ALT) positive, or no identified TMM.
Time frame Up to 10 years
Other outcome
Functional and quality of life outcomes
Will descriptively summarize and compare the total Memorial Symptom Assessment Scale scores, total sub-domain scores, and individual symptom scores between patients randomized to receive dinutuximab during Induction (Arm B) to those of patients randomized to standard Induction (Arm A).
Time frame At serial time points during Induction, Extended Induction, Post-Consolidation, and at the end of therapy
Other outcome
Adequacy of diagnostic biopsy specimens
Will be evaluated by descriptively comparing the successful delineation of histologic classification, MYCN amplification status, and ALK status via the traditional method of obtaining tissue for diagnosis, open surgical biopsy, versus the less invasive percutaneous core needle biopsy.
Time frame At time of tissue collection
Other outcome
Associations between family-reported adverse social determinants of health and both clinical outcomes and biology
Kaplan-Meier curves of EFS and OS will be generated and used to calculate 3-year EFS and OS estimates. Associations between social determinants of health (SDOH) and survival outcomes and time to receipt of dinutuximab will be evaluated with univariate and multivariate Cox proportional hazard models. Log-binomial regression will be used to estimate risk ratios and 95% CI for the occurrence of dinutuximab consent to randomization and therapy receipt by SDOH exposure. Effect modification of outcomes as a function of poverty, stratified by race/ethnicity, will be explored.
Time frame Up to 10 years
Other outcome
Develop and validate deep learning predictors of Induction response (imaging objective)
Scans will be given as input to a convolutional neural network trained to predict EOI response.
Time frame At diagnosis, EOI, during Extended Induction, and end of Extended Induction
Other outcome
Compare institutional versus central determination of overall response, individual response components, and PEIR and GEIR determination (imaging objective)
Will be assessed by calculating the percentage of patients receiving the same EOI institutional and centrally reviewed determination of overall response, individual response components (primary tumor, soft tissue and bone metastatic disease, and bone marrow metastatic disease), and PEIR and GEIR. In addition, Cohen's kappa will be calculated to evaluate the concordance in each of these response measures.
Time frame Up to 10 years
Other outcome
Incidence of late toxicities
Will be addressed by calculating the proportion of treated patients with each late effect, including but not limited to impaired organ function, neuropsychiatric toxicity, and secondary malignancy. A 95% confidence interval will be placed on each proportion.
Time frame Up to 10 years
Other outcome
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
The cumulative incidence of local progression (CILP) in patients with complete response of the primary site at EOI and GEIR on this study will be compared to the CILP rate of 11.2±1.8% observed on ANBL0532 using Gray's test.
Time frame Up to 10 years
Other outcome
Post-transplant complications
Will be evaluated by calculating the incidence of endothelial injury complications and non-relapse mortality within 100 days of transplant, transplant-associated thrombotic microangiopathy (TA-TMA), severe TA-TMA, and sinusoidal obstruction syndrome (SOS) on Arms A and B and comparing between arms with a chi-squared test. 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.
Time frame Up to 100 days post-transplant
Other outcome
Associations between end of induction (EOI) response and individual response components
Log-rank tests will be used to explore the association between EOI response (using both the revised INRC and GEIR/PEIR classification) and individual response components (primary tumor, soft tissue and bone metastatic disease, and bone marrow metastatic disease) with outcome (EFS and OS).
Time frame Up to 10 years
Other outcome
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.
