Evaluation of LY2606368 Therapy in Combination With Cyclophosphamide or Gemcitabine for Children and Adolescents With Refractory or Recurrent Group 3/Group 4 or SHH Medulloblastoma Brain Tumors

NCT04023669 on ClinicalTrials.gov Phase 1 St. Jude Children's Research Hospital (academic or other) Started 2019-08-08 Completed
Riskier than 52% of active trials
this trial: 17% 0% 36%

Model scores of the 29,894 trials active now.

Model score 17% for any early termination, 7% for termination due to slow enrollment. Past trials like this one (phase, sponsor type and disease area, started 2008–2016) ended terminated 23% of the time (1,629 trials).

Finished trial that started in 2015 or later: the model never saw it during training.

How it ended

Completed on 2025-01-13, after 2019-08-08 start.

The score above never used this outcome: finished trial that started in 2015 or later: the model never saw it during training.

Termination over time, as the model saw it at the start

0% 11% 21% 32% 43% 0123456 yr completed 37% terminated 18%

Cumulative chance of ending terminated (red) or completed (green) by each year from its start; it actually ended on 2025-01-13. The rest of the way to 100% is still running.

From the competing-risks survival model (termination vs completion, still-running trials censored), fit to trials that started 2008–2014 and recalibrated to termination rates over 2022–2024, since termination has become more common. Checked on past years, it still ran a little low when the rise continued.

What moved the score

Every input that moved this score, largest first: SHAP contributions in log-odds, red raising risk and green lowering it. They describe the model, not causes of termination. Phrases are traced from the text features back to this registration's words, approximately.
