A Phase Ⅱ Study to Evaluate the Efficacy and Safety of YZJ-4729 in Patients With Moderate to Severe Acute Pain After Abdominal Surgery

Model scores of the 29,894 trials active now.

Model score 9% 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 13% of the time (1,304 trials).

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

Cumulative chance of ending terminated (red) or completed (green) by each year from its start; it actually ended on 2024-08-08. 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.
