About

RATIONALE: Monoclonal antibodies can locate tumor cells and either kill them or deliver tumor-killing substances to them without harming normal cells. Giving monoclonal antibodies in different ways may kill more tumor cells.

PURPOSE: Phase I trial to study the effectiveness of monoclonal antibody therapy in treating patients who have ovarian cancer.

Full description

OBJECTIVES: The primary objective iss to determine the safety of indium (111In) monoclonal antibody (mAb) hu3S193 (111In-hu3S193) given intraperitoneally or intravenously in patients with ovarian carcinoma.

Secondary objectives include comparing the localization of 111In-hu3S193 in ovarian cancer tissue after intraperitoneal vs intravenous injection and the biodistribution and pharmacokinetics of this drug when administered intraperitoneally vs intravenously in these patients as well as the formation of human anti-human antibodies (HAHA) in these patients.

OUTLINE: Patients are assigned to 1 of 2 treatment arms on a first come sequential basis. Arm I: Patients receive indium (In 111) monoclonal antibody hu3S193 (111In-hu3S193) intraperitoneally over 30 minutes. Arm II: Patients received 111In-hu3S193 intravenously (IV) over 30 minutes. Patients were to undergo surgical debulking 3-7 days following In 111In-hu3S193 administration, and biopsy samples obtained to assess radioactive uptake. Immunohistochemistry was also to be performed. Blood samples were to be obtained to assess serum radioactivity. Whole body imaging was tp be performed 3 hours after infusion of radiolabeled monoclonal antibody, on the day of surgery, and at one time point in between. Patients were followed for 30 days.

PROJECTED ACCRUAL: A total of 10 patients (5 per arm) were to be accrued for this study.

Enrollment: 1 patient

Sex: Female

Ages: 18+ years old

Volunteers: No Healthy Volunteers

Exclusion Criteria

Any significant intercurrent medical problems which may limit the amount of antibody they can tolerate, or render them ineligible for surgery.

Intraperitoneal (IP) Infusion of 111In-hu3S193

Experimental group

Description:

Hu3S193 was administered intraperitoneally at a dose of 5 mg radiolabeled with 5 millicurie (mCi) of 111In. Patients received 10 mCi 99mTc-sulphur colloid IP administered in 500 ml of normal saline to assure the absence of any loculation or heterogeneous distribution of radioactivity in the peritoneal cavity. A paracentesis catheter was inserted and the hu3S193 was diluted in 100 mL of 5% human serum albumin and administered as a continuous intraperitoneal infusion over 30 minutes. This was followed immediately by 900 mL of normal saline.

Treatment:

Biological: Monoclonal antibody hu3S193

Intravenous Infusion of 111In-hu3S193

Experimental group

Description:

Hu3S193 was to be administered intravenously at a dose of 5 mg radiolabeled with 5 millicurie (mCi) of 111In, diluted in 100 mL of 5% human serum albumin and administered over a 30 minute period.

Treatment:

Biological: Monoclonal antibody hu3S193
