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.

Protocol

This section provides details of the study plan, including how the study is designed and what the study is measuring.
Design Details
7 patients to be enrolledTotal number of participants that the clinical trial aims to recruit.
Treatment Study
These studies test new ways to treat a disease, condition, or health issue. The goal is to see if a new drug, therapy, or approach works better or has fewer side effects than existing options.

How participants are assigned to different groups/arms
In this clinical study, participants are assigned to groups based on specific criteria, such as their medical history or a doctor's recommendation. This approach ensures that treatments are given to those who may benefit the most, based on known factors.

Other Ways to Assign Participants
Randomized allocation
: Participants are assigned randomly, like flipping a coin, to ensure fairness and reduce bias.

None (Single-arm trial)
: If the study has only one group, all participants receive the same treatment, and no allocation is needed.

How treatments are given to participants
Participants receive treatments one after another in a pre-planned sequence. The next treatment may depend on how the participant responds to the previous one.

Other Ways to Assign Treatments
Single-group assignment
: Everyone gets the same treatment.

Parallel assignment
: Participants are split into separate groups, each receiving a different treatment.

Cross-over assignment
: Participants switch between treatments during the study.

Factorial assignment
: Participants receive different combinations of treatments.

Other assignment
: Treatment assignment does not follow a standard or predefined design.

How the effectiveness of the treatment is controlled
In a non placebo-controlled study, no participants receive an inert substance (placebo) to compare outcomes. Instead, all participants receive either the experimental treatment or an alternative treatment (often the Standard of Care). This method allows researchers to compare the effects of the experimental treatment with those of a different active intervention, rather than a placebo.

Other Options
Placebo-Controlled
: A placebo is used to compare the effects of the experimental treatment with those of an inert substance, isolating the true treatment effect.

How the interventions assigned to participants is kept confidential
Everyone involved in the study knows which treatment is being given. This is typically used when it's not possible or necessary to hide the treatment details from participants or researchers.

Other Ways to Mask Information
Single-blind
: Participants do not know which treatment they are receiving, but researchers do.

Double-blind
: Neither participants nor researchers know which treatment is given.

Triple-blind
: Participants, researchers, and outcome assessors do not know which treatment is given.

Quadruple-blind
: Participants, researchers, outcome assessors, and care providers all do not know which treatment is given.

Criteria

Inclusion Criteria 1. Histologically confirmed non-mucinous ovarian adenocarcinoma. 2. Persistent or recurrent intraperitoneal cancer following platinum/taxane-based therapy for Stage 3 ovarian cancer. 3. Patients with residual disease \< 2cm will be candidates for this study. 4. The following laboratory and clinical results within the last 2 weeks prior to study day 1: Absolute neutrophil count (ANC) ≥ 1.5 x 10\^9/L; Platelet count ≥ 100 x 10\^9/L; Serum bilirubin ≤ 2.0 mg/dL; Aspartate aminotransferase (AST) ≤ 2.5 x upper limit of normal (ULN); Alanine aminotransferase (ALT) ≤ 2.5 x ULN; Serum creatinine ≤2.0 mg/dL; Forced expiratory volume (FEV1) ≥60% of predicted; Forced vital capacity (FVC) ≥60% of predicted; Diffusion capacity ≥55% of predicted; Left ventricular ejection fraction (LVEF) ≥50%; 5. Karnofsky performance status ≥ 70. 6. Before any trial-specific procedures or treatment can be performed, the patient or legally authorized guardian or representative must give witnessed written informed consent for participation in the trial. 7.

Study Objectives
Primary Objectives

All adverse events were graded according to the National Cancer Institute Common Toxicity Criteria (CTC) Scale (Version 2.0, published April 30, 1999). DLT was defined as: * Any Grade 3 or greater non-hematological toxicity (except for alopecia, nausea, and vomiting, defined separately below) * Any Grade alopecia * Grade 4 nausea or vomiting ≥ 5 days duration. * Any Grade 4 hematological toxicity (except for toxicity of ≤ 5 days duration without growth factor, platelet, or transfusion support). To be dose limiting, an adverse event must be definitely, probably, or possibly related to the administration of the investigational agent.
Secondary Objectives

Serum samples were taken 5 min, 1 hour, and 2 hours after end of infusion, twice on study day 2, and daily on study days 3 to 7, 8, 15 and 22. Serum samples were analyzed in a gamma well counter. Elimination half-life (T1/2) was generated by fitting effective clearance to a monoexponential curve.

Blood samples were taken at baseline and on days15, 28 and 56. HAHA was measured by BIACORE.
