Rapid Administration Pilot for Infusing Dinutuximab

• Status: Not yet recruiting
• Trial end date: 2024-08-01
• Target enrollment: 0
• Participant gender: All

Summary

Studies have shown that the anti-GD2 human-mouse chimeric monoclonal antibody dinutuximab has contributed significantly to the improvement of treatment for children with high-risk neuroblastoma and has become a mainstay in treating high risk neuroblastoma in children as part of up-front therapy and relapsed/refractory therapy. The administration of dinutuximab requires a significant amount of time and resources to complete the 10-20 hour standard infusion time for 4 days in the inpatient setting. During its early development, a phase I study profiling the clinical efficacy and tolerability of dinutuximab infusions in children successfully infused dinutuximab at various rates including over 1 hour at different dose levels. In the adult setting, dinutuximab has been tolerated over substantially shorter infusion times (less than 2 hours). Additionally, another anti-GD2 murine monoclonal antibody naxitamab, which has a similar toxicity profile to dinutuximab, is FDA approved for administration over 90 minutes and is successfully administered in outpatient setting. Given this reassuring data we aim to evaluate the feasibility of the rapid administration of dinutuximab over four hours or less in our patient population of children with high-risk neuroblastoma. The pharmacokinetics, toxicity profile and supportive care requirements will be analyzed and described in order to determine if rapid infusion of dinutuximab can be successfully tolerated over four hours or less which would allow for administration of this agent in the outpatient setting. Should this trial prove to be successful, it would serve to decrease the hospital burden in a positive way by allowing for administration of this immunotherapy agent in the outpatient setting and patients may prefer shorter infusion duration. Furthermore, it could lessen overall costs and inpatient admissions for patients.

Criteria

Inclusion Criteria:

• Age: Patients ≥ 12 months of age at the time of enrollment are eligible for this study.

• Diagnosis: Patients must have a diagnosis of relapsed , refractory (defined as achieving less than a partial response), or persistent high risk neuroblastoma or ganglioneuroblastoma (nodular) [verified by tumor pathology analysis or demonstration of clumps of tumor cells in bone marrow with elevated urinary catecholamine metabolites at the time of diagnosis] and have been designated as having high-risk disease based on COG risk classification.

No minimal sites of disease are required for this study.

Prior Therapy (all timeframes below apply from time of enrollment):

• Must have completed high-risk Induction therapy with at least 4 cycles of chemotherapy.

• At least 14 days must have elapsed since completion of myelosuppressive therapy.

• Patients must have received previous treatment with dinutuximab (with or without chemotherapy).

• Anti-cancer agents not known to be myelosuppressive (e.g. not associated with substantially reduced platelet or ANC counts) are permitted while on study with PI approval. However, they must be held during protocol therapy. The anti-cancer agent may be resumed after completion of final dinutuximab day in each cycle per physician discretion.

• Antibodies: ≥ 21 days must have elapsed from infusion of last dose of antibody, and toxicity related to prior antibody therapy must be recovered to Grade ≤ 1.

• Immnoglobulins: IVIG should not be given within 2 weeks of starting dinutuximab treatment and 1 week after completing dinutuximab therapy.

• Patients must have been off pharmacologic doses of systemic steroids for at least 7 days prior to enrollment.

• Patients who require or are likely to require pharmacologic doses of systemic corticosteroids while receiving treatment on this study are ineligible. (The only exception is for patients known to require 2mg/kg or less of hydrocortisone, or an equivalent dose of an alternative corticosteroid, as premedication for blood product administration in order to avoid allergic transfusion reactions). The use of conventional doses of inhaled steroids for the treatment of asthma is permitted, as is the use of physiologic doses of steroids for patients with known adrenal insufficiency.

• Radiation may be given up to 1 week prior to enrollment if clinically indicated. Palliative radiation while on study is permitted but not during infusion days.

• Stem cell transplant may have been given at least 42 days prior to enrollment as long as hematologic and other eligibility criteria have been met to enroll. Patients who received autologous stem cell infusion to support non-myeloablative therapy (such as 131 I-MIBG) are eligible at any time as long as they meet the other criteria for eligibility.

• 131I-MIBG therapy: Patients are eligible ≥6 weeks after therapeutic 131I-MIBG provided that all other eligibility criteria are met.

• Prior or planned concomitant treatment with eculizumab is permitted (e.g., treatment of TA-TMA).

Adequate Bone Marrow Function Defined As:

• Peripheral absolute neutrophil count (ANC) ≥750/microL

• Platelet count ≥50,000/mL (transfusion independent for prior 7 days). Exemptions may be granted for patient specific criteria (i.e. low platelet function due to history of extensive prior therapy or bone marrow disease)

• Hematologic growth factor may given up to 14 days prior to enrollment

Adequate Renal Function Defined As:

• Creatinine clearance or radioisotope GFR ≥70mL/min/1.73m2 or

• Adequate serum creatinine based on age/gender

Note: Patients with history of transplant-associated thrombotic microangiopathy (TA-TMA) must have a creatinine clearance or radioisotope GFR at baseline to assess renal function and must meet the above criteria.

Adequate Liver Function Defined As:

• Total bilirubin ≤1.5 x ULN for age AND

• SGPT (ALT) ≤ 5.0 x ULN for age (≤ 225 U/L). For the purpose of this study, the ULN for SGPT is 45U/L.

Adequate Central Nervous System Function Defined As:

• Patients with a history of CNS disease must have no clinical evidence of active progressive CNS disease at the time of study enrollment. Patients with history of CNS disease need to have at least stable tumor in the CNS for at least one month.

• Patients with seizure disorders may be enrolled if seizures are well controlled on antiepileptic medication

• CNS toxicity ≤ Grade 2

Adequate Cardiac Function Defined As:

• Shortening fraction of ≥27% by ECHO, or

• Ejection fraction of ≥50% by ECHO or gated radionuclide study.

Adequate Pulmonary Function Defined As: No evidence of dyspnea at rest, no exercise intolerance, no chronic oxygen requirement, and room air pulse oximetry >94% if there is a clinical indication for pulse oximetry. For patients who do not have respiratory symptoms, full PFTs are NOT required.

Exclusion Criteria:

• Men and women of childbearing potential and their partners must agree to use adequate contraception while enrolled on this study.

• Females of childbearing potential (≥ 10 years of age and /or post-menarchal) must have a negative pregnancy test to be eligible for this study, and they must agree to use 2 acceptable methods of contraception or abstain from heterosexual intercourse while participating in this study.

• Pregnant women will be excluded from this study.
