Study of GSK3359609 and Pembrolizumab in Programmed Death Receptor 1-ligand 1 (PD-L1) Positive Recurrent or Metastatic Head and Neck Squamous Cell Carcinoma

Model scores of the 29,894 trials active now.

Model score 23% for any early termination, 3% 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 (927 trials).

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

Cumulative chance of ending terminated (red) or completed (green) by each year from its start; it actually ended on 2023-06-20. 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.

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.
