Phase II Study With Catumaxomab in Patients With Gastric Cancer After Neoadjuvant CTx and Curative Resection

The safety and scientific validity of this study is the responsibility of the study sponsor and investigators. Listing a study does not mean it has been evaluated by the U.S. Federal Government. Read our disclaimer for details. Identifier: NCT00464893

Brief Summary:
Primary evaluation of the safety, tolerability and feasibility regarding specific postoperative complications of an adjuvant treatment with catumaxomab administered after curative tumor resection subsequent to a neoadjuvant chemotherapy.

Condition or disease Intervention/treatment Phase
Gastric Cancer Gastric Adenocarcinoma Drug: Catumaxomab Drug: catumaxomab Phase 2

Detailed Description:

An open-label, multi-center phase II study in surgically resectable patients after neoadjuvant ECX-chemotherapy, with confirmed diagnosis of gastric adenocarcinoma and with a high risk of disseminated tumor cells due to serosal infiltration or positive lymph nodes after curative gastrectomy.

Treatment with catumaxomab will consist of an initial dose of 10 µg given intraoperatively as an intraperitoneal bolus and of four postoperative ascending doses (10-20-50-150 µg)which will be administered as an i.p.-infusion using an installed abdominal i.p.-port on the postoperative days 7, 10, 13 and 16.

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.

Arm Intervention/treatment
Active Comparator: catumaxomab arm
Patients will get first the chemotherapeutic regimen (Epirubicin, Cisplatin and Capecitabine or 5-Fluorouracil) consisting of three 21-day cycles, starting on the weeks 1, 4 and 7. Four weeks after CTx the D2 surgery will take place. Treatment with catumaxomab will consist of an initial dose of 10µg given intraoperatively as in intraperitoneal bolus and of four postoperative ascending doses.
Drug: Catumaxomab
10 µg intraoperative and 4 ascending doses (10, 20, 50 and 150 µg) on day 7, 10, 13 and 16
Other Name: Removab

Drug: catumaxomab
10 µg intraoperatively and 4 ascending doses: 10, 20, 50 and 150 µg
Other Name: Removab

Primary Outcome Measures :
  1. rate of all specific postoperative complications newly observed during a period of 30 days after surgery in those study patients who received at least the first 3 doses of catumaxomab [ Time Frame: 30 days after last catumaxomab administration ]

Secondary Outcome Measures :
  1. frequency, relationship and seriousness of adverse events [ Time Frame: 30 days after last catumaxomab administration ]
  2. surgical resection rate [ Time Frame: after surgery ]
  3. chemotherapeutic response rate [ Time Frame: after neoadjuvant CTx ]
  4. overall survival at 3, 6, 9, 12 and 24 month after EOT, defined as the time from study enrolment until death [ Time Frame: 2 years ]
  5. disease-free survival at 3, 6, 9, 12 18 and 24 months after EOT, defined as the time from study enrolment to the point of diagnosis of recurrent disease or death, whichever occurred first [ Time Frame: 2 years ]
