A Study to Investigate the Safety and Immunogenicity of Different Formulations of GSK Biologicals' Meningococcal ACWY Conjugate Vaccine (GSK3536820A and Menveo) Administered to Healthy Adolescents and Young Adults 10 to 40 Years of Age

Model scores of the 29,894 trials active now.

Model score 3% for any early termination, 0% for termination due to slow enrollment. Past trials like this one (phase, sponsor type and disease area, started 2008–2016) ended terminated 19% of the time (731 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 2019-12-17. 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.
