This study aimed (1) to develop a semimechanistic pharmacokinetic (PK) model for nimotuzumab in patients with advanced breast cancer and (2) to identify demographic, biochemical, and clinical predictive factors of the PK variability. Data from a phase 1 study were analyzed using the nonlinear mixed-effects approach (NONMEM). A target-mediated disposition model that included 2 open PK compartments, the monoclonal antibody (mAb)-target binding, and target and mAb-target complex turnovers best described the linear and nonlinear PK.

The present study was conducted to evaluate safety and preliminary efficacy of nimotuzumab, a humanized anti-EGFR antibody in combination with radiation and chemotherapy in advanced esophageal tumours.
Patients And Methods: A Phase II clinical trial was conducted, where patients received cisplatin, 5-fluorouracil, and radiotherapy, either alone or combined with six weekly infusions of nimotuzumab at the dose of 200 mg.
