Intervention/exposure
Study type
Interventional
Description of intervention(s) / exposure
Treatment: Drugs - Capecitabine
Treatment: Drugs - 131I-huA33 (131-Iodine on humanised monoclonal antibody A33)

Experimental: Cohort 1 - 20 millicurie (mCi) 131I-huA33, 1500 mg/m2/day capecitabine
All patients received an initial dose of 5 mg huA33 conjugated to 5-8 mCi 131I on day 0.
This was followed 7 ± 2 days later by inpatient administration of a single infusion of 131I-huA33 with a constant protein dose of 10 mg/m2 huA33.
Capecitabine was administered in 2 divided doses per day on days 1-14 of each 21-day cycle for a total of 4 cycles. Daily doses were rounded to the nearest 150 mg.

Experimental: Cohort 2 - 30 millicurie (mCi) 131I-huA33, 1500 mg/m2/day capecitabine
All patients received an initial dose of 5 mg huA33 conjugated to 5-8 mCi 131I on day 0.
This was followed 7 ± 2 days later by inpatient administration of a single infusion of 131I-huA33 with a constant protein dose of 10 mg/m2 huA33.
Capecitabine was administered in 2 divided doses per day on days 1-14 of each 21-day cycle for a total of 4 cycles. Daily doses were rounded to the nearest 150 mg.

Experimental: Cohort 3 - 30 millicurie (mCi) 131I-huA33, 1000 mg/m2/day capecitabine
All patients received an initial dose of 5 mg huA33 conjugated to 5-8 mCi 131I on day 0.
This was followed 7 ± 2 days later by inpatient administration of a single infusion of 131I-huA33 with a constant protein dose of 10 mg/m2 huA33.
Capecitabine was administered in 2 divided doses per day on days 1-14 of each 21-day cycle for a total of 4 cycles. Daily doses were rounded to the nearest 150 mg.

Experimental: Cohort 4 - 40 millicurie (mCi) 131I-huA33, 1000 mg/m2/day capecitabine
All patients received an initial dose of 5 mg huA33 conjugated to 5-8 mCi 131I on day 0.
This was followed 7 ± 2 days later by inpatient administration of a single infusion of 131I-huA33 with a constant protein dose of 10 mg/m2 huA33.
Capecitabine was administered in 2 divided doses per day on days 1-14 of each 21-day cycle for a total of 4 cycles. Daily doses were rounded to the nearest 150 mg.

Experimental: Cohort 5 - 40 millicurie (mCi) 131I-huA33, 1250 mg/m2/day capecitabine
All patients received an initial dose of 5 mg huA33 conjugated to 5-8 mCi 131I on day 0.
This was followed 7 ± 2 days later by inpatient administration of a single infusion of 131I-huA33 with a constant protein dose of 10 mg/m2 huA33.
Capecitabine was administered in 2 divided doses per day on days 1-14 of each 21-day cycle for a total of 4 cycles. Daily doses were rounded to the nearest 150 mg.


Treatment: Drugs: Capecitabine
Capecitabine was administered orally at doses between 1000 and 1500 mg/m2/day depending on assigned dose level for 14 days per 21-day cycle. Daily doses were rounded to the nearest 150 mg.

Treatment: Drugs: 131I-huA33 (131-Iodine on humanised monoclonal antibody A33)
All patients received a dose of 5 mg huA33 conjugated to 5-8 mCi 131I. The therapy dose of 131I-huA33 comprised a constant protein dose of 10 mg/m2 huA33 regardless of dose level. The 131I-huA33 therapy dose was determined by the assigned dose level (i.e. 20, 30 or 40 mCi/m2 131I).
