Objective Response Rate (ORR)  Undisclosed
Phase 1
A phase 1 study that patients with advanced solid tumors and documented CanAg expression were treated with escalating doses of cantuzumab mertansine IV administered three-times a week in a 3 out of 4 weeks schedule. Twenty patients (pts) with colon (11/20),rectal carcinomas (2/20),or other malignancies (7/20) were treated with doses ranging from 30 to 60 mg/m2 per day of cantuzumab mertansine IV three-times a week.

Patients Enrolled
Histological documentation of advanced or metastatic epithelial solid tumor which were likely to express the CanAg antigen, that were refractory or resistant to standard chemotherapy, or for which no effective standard therapy exists.
Administration Dosage
IV infusion at an initial dose of 30 mg/m2, three times per week for three consecutive weeks for a total of nine doses.
Experiment 2 Reporting the Activity Date of This ADC [4]
Patients Enrolled
Solid malignancies refractory to standard therapy or for whom no standard therapy existed.
Administration Dosage
IV cantuzumab mertansine was administered at a rate of 1 mg/min for 30 minutes and then increased to 3 mg/min if hypersensitivity phenomena were not observed. Treatment courses were repeated every 3 weeks.
