Study of IMC-1121B in Patients With Advanced Solid Tumors

Cycle 1: Upon completion of enrollment criteria confirmed at screening, the first dose of study medication should be administered within 7 days. The infusion will be planned every 2 weeks or every 3 weeks on the same day of the week of the first infusion. Dose escalation to Cohort 2 may occur in the absence of a dose-limiting toxicity (DLT) in the first three participants treated in Cohort 1 during the initial 6-week dosing period (Cycle 1). The same procedure will be followed for dose escalation from Cohort 2 to Cohort 3. If 1 of 3 participants in any cohort experiences a DLT in the first 6 weeks (Cycle 1), 3 additional participants will be enrolled in that cohort. Dose escalation to the next cohort may occur if less that 2 of 6 participants experience a DLT during Cycle 1.
