Phase 2 Safety and Efficacy Study of Zilucoplan (RA101495) to Treat PNH Patients
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 25% of the time (96 trials).
Finished trial that started in 2015 or later: the model never saw it during training.
How it ended
Completed on 2018-03-28, after 2017-03-08 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
Cumulative chance of ending terminated (red) or completed (green) by each year from its start; it actually ended on 2018-03-28. 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.
