Study summary

The aim of the STEP registry is to collect and evaluate experience and data on the diagnosis and treatment of rare childhood tumors in order to use the knowledge gained to improve the treatment prospects for our patients. The rarity of a disease should not be a disadvantage for the young patients.

Read the detailed description

The objective of the STEP registry is to optimise the diagnosis and treatment of patients with rare tumour diseases in childhood and adolescence. Therefore, a continuous prospective collection of clinical data on rare paediatric tumours is conducted to improve the understanding of these tumours. Beyond analysis of clinical data, further scientific research on the biological and molecular genetic characteristics of these tumours is performed. These data and a close collaboration with international partners, especially the European EXPeRT group, enable the improvement of treatment recommendations for these tumours along with establishment a global interdisciplinary network of rare tumour specialists.

Timeline

Tracking since Sep 25, 2026
ElapsedEstimatedEstimated, not yet reachedSimilar studies: half by the dot; the band is the middle halfHalf of similar studies reached it by the dot; the band is the middle half, from a quarter to three quarters

Started Jan 2023 (actual). Primary completion is estimated for Jan 2050, 324 months after the start.

Of 71 observational studies under Rare Diseases, half reached primary completion within 124 months of starting (the median), counting those still running; a quarter within 67 and three quarters within 183. This study's planned 324 months is above that.

Rare Diseases covers many different conditions, not one, so the studies compared here vary widely. Read these figures as a rough guide.

What these dates mean
Start.
When the first participant enrolled; while estimated, when the study expects to open to recruitment.
Primary completion.
When the last participant was examined or treated to collect data for the study's main question, its primary outcome. A study that stopped early gives the date its data collection stopped.
Completion.
When the last participant's last visit took place, for every outcome, secondary ones and side effects included: the end of the study. Often later than primary completion, sometimes the same day.
Actual and Est.
Actual means the registry says the date has happened. Est. (estimated) is a date the sponsor plans or expects. It can still move, and the sponsor is expected to change it to actual once it has passed.
No changes since tracking began. The registry record was last updated on Oct 1, 2024, before this site started recording changes on Sep 25, 2026. Its history is on ClinicalTrials.gov ↗
