Brief Summary:
The purpose of this study is to determine whether the investigational drug catumaxomab delivered in the planned treatment schedule is a safe and effective treatment for women with advanced ovarian cancer who experience a complete response to chemotherapy.

Condition or disease Intervention/treatment Phase
Ovarian Cancer Drug: catumaxomab Phase 2

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 epithelial cell adhesion molecule (EpCAM) on tumor cells and CD3 (cluster of differentiation 3) 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.

Official Title: An Open-Label, Single-Arm, Phase II Safety and Tolerability Study of Catumaxomab (Anti-EpCAM x Anti-CD3) in Women With Advanced Epithelial Ovarian Cancer After a Complete Response to Chemotherapy
Study Start Date : September 2006
Actual Primary Completion Date : February 2008
Actual Study Completion Date : February 2008

Arm Intervention/treatment
Experimental: catumaxomab Drug: catumaxomab
Catumaxomab administered as four 3-hour, constant-rate, intraperitoneal (IP) infusions of 10, 20, 50, 150 microgram (mcg).
Other Name: Removab

Primary Outcome Measures :
  1. Number of Participants Who Completed a 4-dose Series of Catumaxomab Infusions (Defined as 10-20-50-150 Micrograms) Within 21 Days [ Time Frame: 21 days ]

Secondary Outcome Measures :
  1. Number of Participants With Negative (Undetectable) Humoral Immune Responses to Catumaxomab Therapy [ Time Frame: 2 months ]
    Humoral immune response of participants with functional immune system to catumaxomab can provide important information regarding why a therapy may work for some participants and not for others. An undetectable humoral response by itself does not necessarily imply lack of study drug activity. Humoral response is one of the possible selected measurements of the study drug activity at a time point in the study.

  2. Number of Participants With no Residual Disease Prior to Catumaxomab Treatment Via 2nd-look Laparoscopy or Laparotomy (These Procedures Are Optional) [ Time Frame: Baseline ]
  3. Median Time of Progression-free Survival in Weeks (Post-study for 24 Months) [ Time Frame: 2 years ]
  4. Number of Participants Who Survived (Post-study at 24 Month Visit) [ Time Frame: 2 years ]
    Number of participants who survived (post-study at 24 month visit) is the number of participants who did not die

  5. Number of Participants With no Residual Disease at 3 Months After Catumaxomab Treatment Via 3rd-look Laparoscopy or Laparotomy (These Procedures Are Optional) [ Time Frame: 3 months ]
