Study to Evaluate Safety and Tolerability of CC-91633 (BMS-986397) in Participants With Relapsed or Refractory Acute Myeloid Leukemia or Relapsed or Refractory Higher-Risk Myelodysplastic Syndromes

NCT04951778 on ClinicalTrials.gov Phase 1 Celgene (industry) Started 2021-12-02 Terminated
Riskier than 45% of active trials
this trial: 16% 0% 36%

Model scores of the 29,894 trials active now.

Model score 16% 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 (1,938 trials).

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

How it ended

Terminated on 2025-07-30, after 2021-12-02 start.

Reason given by the sponsor: “efficacy”

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 2025-07-30. 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.

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.
