Dose-Tolerability Titration Study to Evaluate The Efficacy And Safety Of Perampanel (E2007) In Patients With Post-Herpetic Neuralgia (PHN)

Model scores of the 29,894 trials active now.

Model score 14% for any early termination, 2% for termination due to slow enrollment. Past trials like this one (phase, sponsor type and disease area, started 2008–2016) ended terminated 19% of the time (731 trials).

Finished trial that started 2008–2014: scored by a model trained without any trial from its start year, so its own outcome was never used.

Cumulative chance of ending terminated (red) or completed (green) by each year from its start; it actually ended on 2009-03-31. 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.

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.
