Brief Summary:
The purpose of this study is to assess the PK, safety, and tolerability of patritumab produced by a new manufacturing process (denoted as "Process 2 patritumab"). The data from this study will allow Process 2 patritumab to be compared to Process 1 patritumab to allow for any dose adjustments, if needed, and to bridge data from studies previously conducted with Process 1 patritumab to studies to be conducted with Process 2 patritumab. The hypothesis for this study is that the pharmacokinetics of Process 2 patritumab will be comparable to those of Process 1 patritumab.

Condition or disease Intervention/treatment Phase
Solid Tumors Drug: patritumab Phase 1

Detailed Description:
Process 2 patritumab will be administered intravenously as a single, loading dose of 18 mg/kg over approximately 60 minutes at Cycle 1 Day 1 followed by 9 mg/kg administered every 21 days as a maintenance dose starting at Cycle 2 Day 1. This study will be conducted in 2 phases: a main study and an extension phase. The PK profile of Process 2 patritumab will be compared to historical data for Process 1 patritumab. Specifically, the PK parameters (AUC0-21d and Cmax as primary endpoints) for Process 2 patritumab 18 mg/kg (loading dose) will be compared to the PK parameters of Process 1 patritumab 18 mg/kg. Process 2 patritumab serum concentrations will be compared to Process 1 patritumab serum concentrations collected in the Phase 1 and Phase 2 studies by population PK methods and will be reported separately.
