Starting result

This result reflects the starting settings. Run your changes to update it.

This scenario result is temporarily unavailable.

Model inputs

Five scientist-facing controls at most.

How do dose regimen and body size change pembrolizumab concentration and cumulative exposure?

exploratory clearance L day

Model parameter controlling exploratory clearance l day.

Exploratory range around the default value.

5 evenly spaced values in L/day. Other model inputs and the simulation window stay fixed.

Interpret with care

  • Interpret trajectories as deterministic model behavior, not as a patient-specific prediction or dosing recommendation.
  • Paper-result and exact-anchor checks remain in the private validation lane and are not part of this public scenario.

Review the server-confirmed fixed price before starting the comparison.

Comparative response

End-of-window response across the selected parameter values.

Choose an exploratory range around the default, review the fixed price, and run the comparison.
