Data from 40 patients are planned to be included in the study to randomize approximately 10 patients.
This study involves patients with advanced/metastatic GD2-positive rhabdomyosarcoma after progression on 1st line of chemotherapy, advanced/metastatic GD2-positive Ewing sarcoma after progression on 1st line of chemotherapy and advanced/metastatic GD2-positive osteosarcoma after progression on 1st line of chemotherapy.
All patients will receive therapy until disease progression (a total of 6 courses of immunotherapy).
The primary objective of the study is to determine the efficacy and safety of dinutuximab beta with investigator's choice of chemotherapy.
Data from 40 patients are planned to be included in the study to randomize approximately 10 patients.
This study involves patients with advanced/metastatic GD2-positive rhabdomyosarcoma after progression on 1st line of chemotherapy, advanced/metastatic GD2-positive Ewing sarcoma after progression on 1st line of chemotherapy and advanced/metastatic GD2-positive osteosarcoma after progression on 1st line of chemotherapy.
6 cycles of treatment with dinutuximab beta are provided in combination with 6-8 cycles of chemotherapy during the induction therapy phase. Switching from one chemotherapy regimen to another is not allowed. Dinutuximab beta should be administered as a slow intravenous infusion through a separate catheter using an infusion pump.
All patients will receive therapy until disease progression (a total of 6 courses of immunotherapy).
Treatment response will be assessed by the investigator after 2, 4 cycles of treatment and at the end of the reinduction therapy period (i.e., after 6 cycles of dinutuximab beta treatment and 6 - 8 cycles of polychemotherapy). Treatment response will be assessed by tumor response according to the criteria for response assessment in the treatment of solid tumors (RECIST 1.1).
After discontinuation of therapy, all patients will be followed up for 6 months. All patients should be followed up to assess survival unless consent is withdrawn. Long-term follow-up/survival assessment visits will be performed monthly until death, withdrawal of consent, or study termination, whichever occurs first.
258 studies on the registry are indexed under Bone Neoplasms; 68 are open to participants now.
This study's planned enrollment of 40 is close to the median of 44 across 163 interventional studies indexed under Bone Neoplasms.

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.
Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.
You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.
The diagnosis was confirmed by looking at a sample under a microscope: tissue from a biopsy or surgery (histology), or cells from a fluid or needle sample (cytology).

Relapsed: the illness came back after treatment had worked. Refractory: it did not respond to treatment, or stopped responding while still on it.
A 0–100 scale of how well someone can carry out everyday activities. 100 is no complaints and no signs of illness; 70 is able to look after yourself but not to work or keep up normal activity; 50 is needing considerable help and frequent medical care.
Studies often ask for 60 or 70 and above. Your doctor gives the score.
A scale of how much an illness limits everyday activity. For people being assessed to join a study, scores run from 0 (fully active) to 4; lower is more active.
Studies most often ask for 0–1 or 0–2. Your doctor gives the score; the WHO scale uses the same steps. The full scale also has 5, which records death.
A recording of the heart’s electrical activity, taken with stickers on the chest, arms and legs. It takes a few minutes and does not hurt.
The share of blood the heart’s main pumping chamber (the left ventricle) pushes out with each beat, measured by an echocardiogram (heart ultrasound) or a MUGA scan. About 50–70% is normal.
The top of the normal range for a blood test, as set by the laboratory that runs it. Each lab prints its own range next to your result.
“≤ 2.5 × ULN” means the result can be up to two and a half times that top value.
Two enzymes measured in a routine blood test of the liver. Higher levels can mean the liver is under strain or damaged. SGPT and SGOT are older names for ALT and AST.
Criteria usually give a limit as a multiple of the upper limit of normal (ULN), often higher when cancer has spread to the liver.
Blood cells that help blood clot. Too few raises the risk of bleeding and bruising. A usual adult range is about 150–400 × 10⁹/L (150,000–400,000 per µL); each lab has its own reference range.
The study doctor’s estimate of how long someone is likely to live. Criteria use it so that people can stay in the study long enough for it to answer its question.
Cancer that has spread from where it began to other parts of the body. “Metastatic” cancer is cancer that has spread this way.
