  • Research summary

    Neuroblastoma is the most common paediatric extra-cranial solid tumour. Between a half and two thirds of patients will have high-risk disease. Despite highly intensive and varied treatments, these patients still experience a low long-term survival of about 50% and chances of survival after disease recurrence are poor. The study aims to improve the survival and quality of life of children and young people with high-risk neuroblastoma and gain knowledge to improve the treatment of other patients in the future. The countries taking part in the study are: Denmark, Finland, Iceland, Norway, Sweden, Lithuania, the Netherlands and UK. This trial is funded in the UK by Cancer Research UK and Novartis. The treatment plan includes 2 intravenous injections, 2 weeks apart, of a radioactive substance called 177Lutetium-DOTATATE (LuDO). LuDO targets somatostatin receptors, which are proteins present in the majority of neuroblastoma tumours in children. In a previous study with LuDO, the treatment was shown to be safe, and some signs of efficacy were seen, but the trial did not achieve the anticipated effect with the low-dose schedule used. The now proposed study (LuDO-N) will use a higher dose of LuDO, given over a shorter period of time, and aims to 1. confirm the dose, 2. assess response to the treatment LUDO in patients with relapsed or refractory high-risk neuroblastoma, 3.assess long term survival and 4. any treatment-related toxicity. This strategy requires a readiness for stem cell transplantation in all patients but is not expected to increase the risk of long-term side effects. The duration of the trial is 5 years from the end of treatment. The study will contribute to develop a new type of targeted treatment that, if shown to be effective, may be beneficial for patients in future international treatment protocols.
