Study information

Scientific title

A Phase IIa trial of 177 177 lutetium dotatate in children with primary refractory or relapsed high-risk neuroblastoma



Study hypothesis

High-risk neuroblastoma is a common childhood cancer. Initial standard chemotherapy treatment produces responses in about two thirds of patients, many of whom will later relapse. The others have primary refractory disease. Overall cure rates are low, and so effective new treatments are needed.

Many neuroblastoma cells express somatostatin receptors. Radiolabelled octreotide analogues can be used for nuclear medicine imaging and therapy of somatostatin receptor positive tumours. 68Ga DOTATATE and 177Lu DOTATATE have been shown to be effective octreotide analogues for imaging and treatment respectively of neuroendocrine cancers in adults.

The primary aims of this study are to evaluate the toxicity and the efficacy of 177Lu DOTATATE in children with relapsed or refractory high-risk neuroblastoma. Secondary, translational, aims are to investigate 68Ga DOTATATE PET/CT for imaging of neuroblastoma, in comparison with the standard of 123I-mIBG, to assess the relationship between the expression of somatostatin receptors measured by immunohistochemistry in archived neuroblastoma tissue from each patient with their imaging, and to correlate tumour radiation dosimetry with response.

This will be a Phase II clinical trial using a Simon Two Stage Minimax design. This requires 14 patients in Stage 1. If three or more responses are seen, another 10 patients will be recruited in Stage 2. If eight or more responses are seen in these 24 patients, then the treatment will be deemed worthy of further investigation in this patient group.

177Lutetium DOTATATE: The investigational medicinal product (IMP) for the study. Patients will receive up to a maximum of 4 administrations 8 weeks apart.
68Ga DOTATATE PET/CT: Potential patients for this study will require a 68Ga DOTATATE PET/CT to assess eligibility. Uptake in the tumour at least as high as the uptake in the liver must be demonstrated for a patient to be eligible.
Amino acid solution infusion: An amino acid solution is infused over 4 hours concurrently with the radionuclide administration to reduce renal tubular uptake and minimise nephrotoxicity.
SPECT/CT dosimetry: In radionuclide therapy there is an uncertain relationship between the administered activity (in GBq) of the drug and the absorbed dose (in Gray).
Therefore following administration whole body and SPECT/CT dosimetry will be performed to accurately determine the dose received by the whole body, bone marrow, kidneys and the tumour.
Whole blood profile: Weekly bloods will be taken to perform assessment of haematological toxicity
