Describes the nature of a clinical study. Types include:
- Observational study — observes people and measures outcomes without affecting results.
- Interventional study (clinical trial) — studies new tests, treatments, drugs, surgical procedures or devices.
- Medical records research — uses historical information collected from medical records of large groups of people to study how diseases progress and which treatments and surgeries work best.
During the early phases (phases 1 and 2), researchers assess safety, side effects, optimal dosages and risks/benefits. In the later phase (phase 3), researchers study whether the treatment works better than the current standard therapy. They also compare the safety of the new treatment with that of current treatments. Phase 3 trials include large numbers of people to make sure that the result is valid. There are also less common very early (phase 0) and later (phase 4) phases. Phase 0 trials are small trials that help researchers decide if a new agent should be tested in a phase 1 trial. Phase 4 trials look at long-term safety and effectiveness, after a new treatment has been approved and is on the market.

About this study
This partially randomized phase III trial studies isotretinoin with monoclonal antibody Ch14.18, aldesleukin, and sargramostim to see how well it works compared to isotretinoin alone following stem cell transplant in treating patients with neuroblastoma. Drugs used in chemotherapy, such as isotretinoin, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclonal antibodies, such as monoclonal antibody Ch14.18, can block tumor growth in different ways. Some block the ability of tumors to grow and spread. Others find tumor cells and help kill them or deliver tumor-killing substances to them. Aldesleukin and sargramostim may stimulate a person's white blood cells to kill cancer cells. It is not yet known if chemotherapy is more effective with or without monoclonal antibody Ch14.18, aldesleukin, and sargramostim following stem cell transplant in treating neuroblastoma.
