PHASE2
Brief Summary
The aim of this study is to evaluate the safety and efficacy of 67Cu-SARTATE in pediatric patients with high-risk neuroblastoma.
Detailed Description
This is an 'adaptive trial'. The trial design uses the accumulating data from the ongoing trial to modify aspects of the trial (e.g. dose, number of treatments). The trial is also a 'personalised tria...
Eligibility Criteria
Inclusion
- Participant is able and willing to provide informed consent (≥18 years), or informed consent is obtained by the parent or legal guardian for minor participants, with the minor providing age appropriate assent, according to local law and regulations;
- Life expectancy ≥ 12 weeks for patients in the Dose Escalation Phase or ≥ 4 months for patients in the Cohort Expansion Phase;
- Known high-risk neuroblastoma OR previously intermediate-risk neuroblastoma that has relapsed or progressed to high-risk, with failure to achieve complete response with standard therapy (defined as at least 4 cycles of aggressive multi-drug induction chemotherapy with or without radiation and surgery, or according to a standard high-risk treatment/neuroblastoma protocol), OR who are medically ineligible to receive standard treatment OR who are intolerant to standard treatment;
- Adequate recovery from acute toxic effects of any prior therapy, as deemed by the Investigator or treating Sub-Investigator;
- Adequate liver function as defined by the following laboratory values obtained within 28 days prior to administration of 64Cu-SARTATE: Aspartate aminotransferase (AST) and alanine aminotransferase (ALT) \< 3.0 x upper limit of normal (ULN);
- Adequate renal function;
- Adequate laboratory parameters: Absolute neutrophil count \> 1.0 x 10 9/L; Platelet count \> 50 x 10 9/L; Total bilirubin \<1.5 x ULN;
- Karnofsky or Lansky performance status ≥50;
- All participants must have a hematopoietic stem cell product available (minimum CD34+ cell dose is ≥2 x 10 6 cells/kg);
- Sexually active participants of reproductive potential must practice an effective method of birth control while participating on this study, to avoid possible damage to the fetus. Abstinence is considered acceptable;
- 64Cu-SARTATE uptake on the 4 hour scan (SUVmax) of any lesion equal to or higher than that of the liver in order to move on to the therapy phase of the study.
Exclusion
- Participants with disease of any major organ system that would compromise their ability to tolerate therapy, as deemed by the Investigator or treating Sub-Investigator;
- Participants with intracranial tumor affecting the brain parenchyma that has not been previously treated at the time of study enrolment;
- Any other active malignancy, or a history of prior malignancy within the past 3 years;
- History of cardiac failure as evidenced by: dyspnea at rest, exercise intolerance, oxygen requirement, clinically significant cardiac dysfunction;
- Planned administration of chemotherapy, anti-cancer cytokine therapy, immunotherapy or radiotherapy within 2 weeks prior to the administration of 64Cu-SARTATE;
- Administration of therapeutic dose of 131I-MIBG within 8 weeks prior to the administration of 64Cu-SARTATE;
- External beam radiation therapy (EBRT) to both kidneys or a single functioning kidney within 12 months prior to the administration of 64Cu-SARTATE;
- Administration of any investigational agents within 21 days prior to administration of 64Cu-SARTATE;
- Treatment with long acting somatostatin analogues (administered within 28 days prior to the administration of 64Cu-SARTATE), or short acting somatostatin analogues (administered within 24 hours prior to the administration of 64Cu-SARTATE);
- Known sensitivity or allergy to somatostatin analogues;
- Previous peptide receptor radionuclide therapy (PRRT);
- Female participants who are pregnant or lactating;
- Participants who are on hemodialysis;
- QTcF interval ≥ 0.45 seconds as measured by Screening ECG;
- Participants with uncontrolled infection(s);
- Any medical condition which the Investigator feels may interfere with the procedures or evaluations of the study;
- Participants 12 months and younger will be excluded from cohorts where the planned single or cumulative administered activity is modelled to deliver a radiation dose to the marrow that exceeds 2 Gy.
