About this trial

The LuDO-N Trial is a multi-centre phase II clinical trial on 177Lu-DOTATATE treatment of recurrent or relapsed high-risk neuroblastoma in children. The LuDO-N Trial builds on the experience from the previous LuDO Trial and utilises an intensified dosing schedule to deliver 2 doses over a 2-week period, in order to achieve a maximal effect on the often rapidly progressing disease. This strategy requires a readiness for autologous stem cell transplantation in all patients, but is not anticipated to increase the risk of long-term sequelae, since the cumulative radiation dose remains unchanged. The primary aim of the study is to assess the response to 177Lu-DOTATATE treatment at 1 and 4 months after ende of treatment. Secondary aims are to assess survival and treatment-related toxicity. Additional aim are to correlate tumour dosimetry with response, correlate SSTR-2 expression with 68Ga-DOTATATE uptake and to correlate the uptake with the treatment response.

Eligibility criteria

This trial does not accept healthy volunteers

Qualifiers

Pathology 1.1. Histologically confirmed diagnosis of neuroblastoma 1.2. Immunohistochemical staining for somatostatin receptors (SSTR) performed from primary tumor tissue when available

Relapsed or primary refractory high-risk neuroblastoma: INSS stage 4 disease or INRGSS stage M disease

Age >18 months at the time of enrolment into this study

Life expectancy of greater than 3 months

Disqualifiers

Not fit enough to undergo proposed study treatment, as assessed by national PI, considering precautions defined in the latest version of the 177Lutetium-DOTATATE SmPC.

Pregnant or lactating patient

Concurrent treatment with any anti-tumor agents

Prior treatment with other radiolabeled somatostatin analogues

Treatments tested in this trial

  • 177Lu-DOTATATE

    Combination product

    A weight-based activity of 200 MBq kg-1 will be used for the first dose. The activity of the second dose will be calculated based on whole body activity scans as well as SPECT CT scans to determine the absorbed kidney dose. The aim is to administer 177Lu-DOTATATE corresponding to a whole-body dose of 1,2 Gy, with a cumulative whole-body dose of about 2,4 Gy over two courses, and not exceeding a cumulative renal dose of 23 Gy, in order to avoid renal toxicity.
