E.2 Objective of the trial |
E.2.1 | Main objective of the trial |
The main objective of this trial is to investigate the efficacy of catumaxomab by determination of the rate of macroscopic complete remissions of peritoneal carcinomatosis after treatment with one cycle (four doses) of catumaxomab followed by six cycles of fluorouracil, leucovorin, oxaliplatin and docetaxel (FLOT) chemotherapy. The primary endpoint is the rate of macroscopic complete remissions of peritoneal carcinomatosis at the second diagnostic laparoscopy or laparotomy. |
|
E.2.2 | Secondary objectives of the trial |
Secondary endpoints to be analyzed in both study arms, (including exploratory comparisons) are:
• Surgical resection rate (R0, R1, R2)
• Overall survival (OS)
• Disease-free survival (DFS)
• Progression-free survival (PFS)
• Immunoreaction against tumor in tissue samples
• Detection of disseminated tumor cells via PCR
• Frequency, relationship, and severity/seriousness of AEs
|
|
E.2.3 | Trial contains a sub-study | No |
E.3 | Principal inclusion criteria |
All patients treated in this trial must fulfil all of the following inclusion criteria:

• Prior anti-cancer chemotherapy or immunotherapy.
• Investigational drug therapy outside of this trial during or within 4 weeks of study entry
• Major surgery within 4 weeks of starting the study, and patients must have recovered from effects of major surgery
• Pregnant or breast-feeding patients, or planning to become pregnant within 6 months after the end of treatment. Women of childbearing potential must have a negative pregnancy test performed within 7 days of the start of treatment. Women enrolled in this trial must use adequate barrier birth control measures during the course of the trial and for 6 months after the end of treatment.
