Radiolabeled Monoclonal Antibody in Treating Patients With Advanced Ovarian Epithelial Cancer

OBJECTIVES: Primary * Determine the safety and maximum tolerated dose of intraperitoneally (IP) administered yttrium-90 (90Y) radiolabeled monoclonal antibody (mAB) hu3S193 (90Y-hu3S193) in patients with advanced ovarian epithelial cancer. Secondary * Determine the localization and whole body and abdominal clearance of 90Y-hu3S193 using indium-111 (111In) radiolabeled hu3S193 and gamma camera imaging. * Determine the serum pharmacokinetics of hu3S193 using gamma well counting. * Determine the antibody response as measured by human anti-human antibody response (HAHA). OUTLINE: This is a dose-escalation study of the yttrium-90 radiolabeled monoclonal antibody, 90Y-hu3S193. Patients received technetium (99mTc-sulfur colloid) IP and underwent abdominal imaging on day 1. Provided the distribution of the 99mTC-sulfur colloid was deemed adequate, patients then received 90Y-hu3S193 IP. 111In-hu3S193 was also administered IP over 30 minutes on day 1 to enable gamma camera imaging. Within 3-5 hours after antibody administration, patients underwent whole body imaging and single-photon emission-computed tomography (SPECT) imaging of the abdomen and pelvis. Cohorts of 3-6 patients were to receive escalating doses of 90Y-hu3S193 until the maximum tolerated dose (MTD) was determined. The MTD was defined as the dose preceding that at which 2 of 3 or 2 of 6 patients experience dose-limiting toxicity. Patients were to be followed every 3 months for at least 2 years and then every 6 months for up to 5 years.
