A Study of TQ-B3525 in Subjects With Relapsed/Refractory Chronic Lymphocytic Leukemia/Small Lymphocytic Lymphoma
Model scores of the 29,894 trials active now.
Model score 12% 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 16% of the time (257 trials).
Finished trial that started in 2015 or later: the model never saw it during training.
How it ended
Terminated on 2023-11-22, after 2021-06-05 start.
Reason given by the sponsor: “business”
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 2023-11-22. 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.
