Further study details as provided by Fresenius Biotech GmbH:

Primary Outcome Measures:

To assess the rate of patients who complete a 4-dose series of catumaxomab infusions (defined as 10-20-50-150 mcg) within 21 days.

Secondary Outcome Measures:

To assess humoral and cellular immune responses to catumaxomab therapy
To evaluate residual disease prior to and 3 months after catumaxomab treatment via 2nd-look and 3rd-look laparoscopy or laparotomy (these procedures are optional).
To assess progression-free survival (post-study for 24 months).
To assess overall survival (post-study for 24 months).

Enrollment:	43

Detailed Description:

A multi-center, phase II study of catumaxomab in ovarian cancer patients who experience a complete response to chemotherapy. Each eligible patient will receive four ascending doses of catumaxomab, administered intraperitoneally via an indwelling catheter or port. Catumaxomab will be administered as a 3-hour constant rate infusion with a dosing interval of 3-4 days. Each patient will participate in this study for up to 4 months (includes the baseline screening period, 11 to 21 days treatment period, and up to 90 days/3 months follow-up), with post-study follow-up every 3 months for 2 years.

Catumaxomab is a trifunctional antibody targeting EpCAM on tumor cells and CD3 on T cells. Trifunctional antibodies represent a new concept for targeted anticancer therapy. This new antibody class has the capability to redirect T cells and accessory cells (e.g. macrophages, dendritic cells [DCs] and natural killer [NK] cells) to the tumor site. According to preclinical data, trifunctional antibodies activate these different immune effector cells, which can trigger a complex anti-tumor immune response.

Eligibility

Ages Eligible for Study:	18 Years and older
Genders Eligible for Study:	Female
Accepts Healthy Volunteers:	No

Criteria

Inclusion Criteria:

Signed and dated informed consent form before any protocol-specific screening procedures
Histologically confirmed diagnosis of epithelial ovarian cancer, fallopian tube, or primary peritoneal cancer, FIGO stage IIb - IV
Optimal or sub-optimal cytoreductive surgery
Clinical complete response to platinum and taxane-based therapy consisting of at least four cycles, based on CT scan and a CA-125 level below 35 U/mL
Age ≥18 years
ECOG performance status of 0 or 1
Last dose of platinum and taxane-based therapy completed within 6 weeks prior to the start of catumaxomab treatment
Negative serum pregnancy test result at screening in women of childbearing potential (applies to patients without documented menopause or sterility)
Willingness of patients of childbearing potential to use an effective contraceptive method (i.e. oral contraceptive, cervical cap, diaphragm with spermicide, condom with spermicide, or intrauterine device) during the study and for at least 6 months after the last infusion

Exclusion Criteria:

Acute or chronic systemic infection
Exposure to chemotherapy, radiotherapy, immunotherapy or investigational anti-cancer therapy within 6 weeks of first dose of catumaxomab other than last regimen of platinum and taxane chemotherapy as outlined in protocol
Known human immunodeficiency virus (HIV) infection
Previous treatment with non-humanized murine (rat or mouse) monoclonal antibodies (mAb)
Inadequate renal function (creatinine > 1.5 x upper limit of normal [ULN])
Inadequate hepatic function:
- Alanine aminotransferase (ALT) > 2.5 x ULN or
- Aspartate aminotransferase (AST) > 2.5 x ULN or
- Bilirubin > 1.5 x ULN
Platelets < 100,000 cells/mm3
Absolute neutrophil count (ANC) < 1,500 cells/mm3
History of myocardial infarction, congestive heart failure or relevant cardiac arrhythmia within the last 6 months
No other malignancy within the past 5 years except non-melanoma skin cancer or carcinoma in situ of the cervix if adequately treated
No history of brain metastases
Any further condition or disease that would, in the opinion of the Investigator, expose the patient to undue risk
