"First Cycle: cG250 10 mg/m² intravenous infusion, weekly for five weeks, followed by a two-week break. 1st \& 5th dose will be trace-labeled with a radioactive substance detectable on a PET scanner (124I-cG250).~Second cycle (investigator discretion): cG250 10 mg/m² intravenous infusion, weekly for four weeks followed by a two-week break. No 124I-cG250 will be used in the 2nd cycle.~Up to 2 cycles available."
