Brief Summary

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.

Outcome Measures

Primary Outcomes (1)

  • Treatment response assessed in accordance with the Revised International Neuroblastoma Response Criteria (INRC) - 1 months after End of Treatment

    Treatment response assessed in accordance with the Revised International Neuroblastoma Response Criteria (INRC)

    1 months following end of treatment

Secondary Outcomes (4)

  • Number and severity of treatment-related adverse events

    Up to 5 years after end of treatment

  • Treatment response assessed in accordance with the Revised International Neuroblastoma Response Criteria (INRC) - 4 months after End of Treatment

    4 months following end of treatment

  • Progression-free survival

    Time from registration to progression or death, up to 5 years following end of treatment

  • Overall survival - up to 5 years after End of Treatment

    Time from registration to the the date of death, up to 5 years following end of treatment

Other Outcomes (3)

  • Tumour dosimetry: absorbed dose per administration of 177Lu-DOTATATE

    At every administered dose of 177Lu-DOTATATE throughout the trial treatment phase (5 years)

  • Correlation of expression of Somatostatin Receptor-2 (SSTR-2) to uptake on 68Ga-DOTATOC PET/CT

    Throughout the trial treatment phase (5 years)

  • Uptake on 68Ga-DOTATOC PET/CT

    At end of treatment, and 1 and 4 months after end of treatment.

Study Arms (1)

177Lu-DOTATATE

EXPERIMENTAL

A total of two doses of 177Lu-DOTATATE will be administered intravenously. The minimum time between treatments is 2 weeks.

Combination Product: 177Lu-DOTATATE

Interventions

177Lu-DOTATATECOMBINATION_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.
