Trial Information

A Double-Blind Placebo Controlled Trial of Intravenous OvaRex MAb-B43.13 as Post Chemotherapy Consolidation for Ovarian Tubal and Peritoneal Carcinoma

OBJECTIVES: I. Compare the time to disease relapse, survival, and quality of life of
patients with stage III or IV ovarian epithelial, tubal, or peritoneal adenocarcinoma
treated with OvaRex monoclonal antibody B43.13 OR placebo following complete clinical
response to primary therapy. II. Determine the safety of this regimen in these patients.
III. Assess the immune response of patients treated with this regimen.

OUTLINE: This is a randomized study. Patients undergo a laparotomy and platinum based
chemotherapy prior to randomization. Patients are randomized to 1 of 2 treatment arms: Arm
I: Patients receive OvaRex monoclonal antibody B43.13 IV on day 0. Treatment continues at 4,
8, 20, 32, 44, and 56 weeks, and then every 3 months in the absence of disease progression
or unacceptable toxicity. Arm II: Patients receive placebo IV on day 0. Placebo
administration continues on the same schedule as in arm I. Patients presenting with relapse
are provided with second line chemotherapy. Quality of life is assessed at the beginning of
the study, after 2 months, and then every 3 months thereafter. Patients are followed every 3

PROJECTED ACCRUAL: A total of 400 patients (200 per arm) will be accrued for this study.

Inclusion Criteria

DISEASE CHARACTERISTICS: Histologically proven stage III or IV ovarian epithelial, tubal,
or peritoneal adenocarcinoma Must have had complete clinical response to primary therapy
consisting of surgical debulking and platinum based chemotherapy Elevated CA 125 (greater

patient must have a serum CA 125 of at least 100 U/mL and strong tumor tissue expression)
Must have residual disease (visible or palpable) at completion of the staging laparotomy
(IIIB and IIIC microscopic disease)

PRIOR CONCURRENT THERAPY: Biologic therapy: At least 6 weeks since prior immunotherapy No
prior murine monoclonal antibodies for diagnostic or therapeutic purposes Chemotherapy: No
more than 1 prior regimen of chemotherapy (change in chemotherapy agents is permitted
during primary therapy provided that the change is considered to be part of initial
chemotherapy regimen) At least 4 weeks since prior chemotherapy Endocrine therapy: Not
specified Radiotherapy: At least 4 weeks since prior abdominal, abdominopelvic, or pelvic
