Study of Pembrolizumab Plus Chemotherapy in Patients With Advanced Cancer (PembroPlus)

NCT02331251 on ClinicalTrials.gov Phase 1/2 Western Regional Medical Center (academic or other) Started 2014-12-31 Terminated
Among the riskiest 1% of active trials
this trial: 43% 0% 36%

Model scores of the 29,894 trials active now.

Model score 43% for any early termination, 13% for termination due to slow enrollment. Past trials like this one (phase, sponsor type and disease area, started 2008–2016) ended terminated 26% of the time (851 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

Terminated on 2018-01-31, after 2014-12-31 start.

Reason given by the sponsor: “other”

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

0% 14% 28% 42% 55% 0123456 yr completed 24% terminated 48%

Cumulative chance of ending terminated (red) or completed (green) by each year from its start; it actually ended on 2018-01-31. 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.

What moved the score

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.
