Recruitment Criteria

Accepts Healthy Volunteers

Healthy volunteers are participants who do not have a disease or condition, or related conditions or symptoms

Study Type

An interventional clinical study is where participants are assigned to receive one or more interventions (or no intervention) so that researchers can evaluate the effects of the interventions on biomedical or health-related outcomes.

An observational clinical study is where participants identified as belonging to study groups are assessed for biomedical or health outcomes.

Searching Both is inclusive of interventional and observational studies.

Abstinence is considered acceptable; 11. 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 Criteria:

Any other active malignancy, or a history of prior malignancy within the past 3 years; 3. History of cardiac failure as evidenced by: dyspnea at rest, exercise intolerance, oxygen requirement, clinically significant cardiac dysfunction; 4. Planned administration of chemotherapy, anti-cancer cytokine therapy, immunotherapy or radiotherapy within 2 weeks prior to the administration of 64Cu-SARTATE; 5. Administration of therapeutic dose of 131I-MIBG within 8 weeks prior to the administration of 64Cu-SARTATE; 6. External beam radiation therapy (EBRT) to both kidneys or a single functioning kidney within 12 months prior to the administration of 64Cu-SARTATE; 7. Administration of any investigational agents within 21 days prior to administration of 64Cu-SARTATE; 8. 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); 9. Known sensitivity or allergy to somatostatin analogues; 10. Previous peptide receptor radionuclide therapy (PRRT); 11. Female participants who are pregnant or lactating; 12. Participants who are on hemodialysis; 13. QTc interval ≥ 0.45 seconds as measured by Screening ECG; 14. Participants with uncontrolled infection(s); 15. Any medical condition which the Investigator feels may interfere with the procedures or evaluations of the study; 16. 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.

Trial Details

Trial ID:

This trial id was obtained from ClinicalTrials.gov, a service of the U.S. National Institutes of Health, providing information on publicly and privately supported clinical studies of human participants with locations in all 50 States and in 196 countries.


Phase 1: Studies that emphasize safety and how the drug is metabolized and excreted in humans.

Phase 2: Studies that gather preliminary data on effectiveness (whether the drug works in people who have a certain disease or condition) and additional safety data.

Phase 3: Studies that gather more information about safety and effectiveness by studying different populations and different dosages and by using the drug in combination with other drugs.

Phase 4: Studies occurring after FDA has approved a drug for marketing, efficacy, or optimal use.

Additional Details

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 trial' as the interval between treatments and number of treatments is determined for each patient individually. This study is to be conducted in 2 phases, a dose escalation phase and a cohort expansion phase. Dose escalation will be completed using a modified 3+3 study design with up to 4 Cohorts of increasing doses in MBq/kg. Pre-defined Dose Limiting Toxicities will be monitored for 6 weeks post administration of 1 therapy cycle of 67Cu-SARTATE. Participants who demonstrate therapeutic benefit (defined as non progression as assessed by the Investigator using the International Neuroblastoma Response Criteria (INRC) guidelines) may be offered additional Therapy Cycles (each participant may receive a maximum of 4 Therapy Cycles in total). Cohort expansion will commence once either the Maximum Tolerated Dose (MTD) for a single administration of 67Cu-SARTATE is established, or Cohort 4 has been completed. The study will be expanded to enroll an additional 10 subjects who will receive at least 2 therapy cycles of 67Cu-SARTATE at the MTD dose level. Participants who demonstrate therapeutic benefit (defined as non progression as assessed by the Investigator using the INRC guidelines) may be offered additional Therapy Cycles (each participant may receive a maximum of 4 Therapy Cycles in total). The study also includes a long-term follow-up period to 36 months following the first dose of 67Cu-SARTATE, although in person study visits are not required.

Arms & Interventions


Experimental: 67Cu-SARTATE

64Cu-SARTATE - patients will receive a bolus injection of 64Cu-SARTATE during screening, and following each 67Cu-SARTATE Therapy Cycle at a rate of 2.0 MBq/kg. 67Cu-SARTATE - In the dose escalation phase, patients will receive a single administration of 67Cu-SARTATE as an IV infusion (dose will be determined based on cohort allocation). In the expansion phase, patients will receive at least 2 administrations of 67Cu-SARTATE a the MTD level as a slow IV infusion. Participants in either phase of the study that demonstrate therapeutic benefit following treatment with 67Cu-SARTATE at any dose may be offered additional Therapy Cycles (each participant may receive a maximum of 4 Therapy Cycles in total).
