|---|---|
| Main Objective: •Decrease of the incidence of clinically significant malignant ascites (defined by one paracentesis of > 1500 ml or a cumulative amount of 1500 ml by multiple paracentesis within 10 days) from 40% (estimated value from the literature) to 15% within 9 months after first catumaxomab therapy. The event will be counted on the day of 2nd paracentesis •Decrease of the incidence of intestinal obstruction with the indication of surgery or parenteral nutrition (> 14 days, > 70% of calorie intake) from to 40% (estimated value from literature and local database) to 20 % within 9 months after first Catumaxomab therapy •Decrease of the incidence of ECOG deterioration from ECOG 1 or 2 to ECOG 3 in within 9 months after first Catumaxomab therapy •decrease of the incidence of death from 60 % to 35% within 9 months after first Catumaxomab therapy ;Secondary Objective: Safety endpoints: -medical incidence to terminate catumaxomab infusion -Frequency, relationship and intensity of clinically relevant grade III and IV adverse events (AEs) Immunological endpoints: -Quality and Quantity of EpCAM-expression on PC samples -Incidence and quality of EpCAM positive Tumor cells in intraperitoneal lavage specimen -Disseminated tumor cells and tumor stem cells in peripheral blood during therapy -Proportion and absolute numbers of leukocytes (T-cells, B-cells, NK cells, macrophages) in peripheral blood -Anti-EpCAM and anti-HER2/neu humoral immune response -VEGF levels during therapy -Induction of human anti-mouse antibodies (HAMA) -Pharmakokinetics: Systemic levels of catumaxomab after i.p. therapy - -Blood samples and tissue samples will be asservated for future anaylsis. Informed consent for storage of the samples will be mandatorily obtained from every involved patient. ;Primary end point(s): Symptom- and progression free survival, defined by the primary end-points: •Incidence of clinically significant malignant ascites (defined by one paracentesis of > 1500 ml or a cumu | — |
