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. • Substance abuse, medical, psychological or social conditions that may interfere with the patient’s understanding of the informed consent procedure, participation in the study or evaluation of the study results.
Design outcomes
Primary
| Measure | Time frame |
|---|---|
| Main Objective: 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.;Secondary Objective: 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 ;Primary end point(s): Macroscopic complete remission (CR) of peritoneal carcinomatosis is the primary endpoint of the study and defined as the disappearance of any malignant peritoneal lesions, according to diagnostic laparoscopy. ;Timepoint(s) of evaluation of this end point: End of neo-adjuvant treatment (aprox. 140 (investigative arm ) /115 (comparative arm) days) | — |
