A Study to Evaluate Safety and Tolerability After Oral Dosing of AZD1656 in Healthy Volunteers
Model scores of the 29,894 trials active now.
Model score 8% for any early termination, 0% for termination due to slow enrollment. Past trials like this one (phase, sponsor type and disease area, started 2008–2016) ended terminated 5% of the time (4,470 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.
How it ended
Completed on 2008-09-30, after 2008-07-31 start.
The score above never used this outcome: 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.
Termination over time, as the model saw it at the start
Cumulative chance of ending terminated (red) or completed (green) by each year from its start; it actually ended on 2008-09-30. 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.
