Study purpose

• How do the model's key biological readouts change under typical male 3mgkg q2w dynamic probe?

Assumptions

• Conditional stationary PK with zero individual deviations and residual noise; no response, survival or toxicity prediction.
• Central and peripheral volumes are structurally equal. Intercompartmental clearance is fixed by the source specification.
• BSA and albumin inputs are positive physical values. Represent a missing covariate by its reference value; never pass a missing-data marker as a physical measurement.
• Dose amounts are fixed at 240 mg, corresponding to 3 mg/kg only at the declared 80 kg administration reference.
• One-hour infusions and zero initial drug are declared scenario assumptions. Original patient dosing histories are not reconstructed.
• Covariate edit bounds are authored exploration bounds; cohort IQRs do not establish a clinical joint domain.
• Reported variability and error terms are documented without population sampling or a fitting likelihood.
