Plain English Summary
Background and study aims
Peritoneal carcinomatosis (PC) is a rare type of cancer that occurs in the peritoneum, the thin layer of tissue that covers abdominal organs and surrounds the abdominal cavity. PC that has spread from gastrointestinal tumours is associated with an average survival of only a few months. There is currently no standard treatment to prevent or eradicate. Various treatments have been tested including peritonectomy (surgery removing most of the peritoneum), or applying chemotherapy directly into the abdominal cavity (intraperitoneal), whether heated (hyperthermic intraperitoneal chemotherapy) or not. No effective treatment is available for patients with PC who are not eligible for surgery to remove the tumour. Chemotherapy has been used with only a small effect on preventing disease progression and symptoms. The aim of this study is t find out whether a two cycle intraperitoneal catumaxomab treatment in addition to standard intravenous chemotherapy (into a vein) is able to increase symptom and progression free survival.
Who can participate?
Patients aged 18 or over with peritoneal carcinomatosis from colorectal or gastric cancer who are not eligible for surgery
What does the study involve?
All participants are treated with intraperitoneal catumaxomab on day 0, 3, 7 and 10 after the start of treatment, followed by intravenous chemotherapy on days 30 to 90. This is followed by a second cycle of intraperitoneal catumaxomab between days 91 and 120, followed by intravenous chemotherapy between days 121 and 180. The study ends at day 270. There is an additional optional follow-up at 15 months.
What are the possible benefits and risks of participating?
The treatment may lead to survival and a reduction or delay of symptoms like ascites and bowel obstruction. Risks of participating include side effects such as fever, nausea, vomiting and abdominal pain.

Study information
Scientific title
Multicentre, open-label phase II study to evaluate the efficacy of a two cycle immunotherapy with the trifunctional bispecific antibody catumaxomab (anti EpCAM x anti-CD3) in addition to systemic chemotherapy in patients with peritoneal carcinomatosis from gastric or colorectal adenocarcinoma
Acronym
Study hypothesis
The main hypothesis is that a two cycle intraperitoneal (i.p.) catumaxomab treatment in addition to standard intravenous (i.v.) chemotherapy is able to increase symptom and progression free survival in patients with peritoneal carcinomatosis of gastric or colorectal origin not eligible for cytoreductive surgery or with no chance to obtain macroscopic complete cytoreduction. According to the primary endpoints this is defined as:
1. Decrease of the incidence of clinically significant malignant ascites
2. Decrease of the Incidence of intestinal obstruction with the need of surgical intervention or parenteral nutrition
3. Decrease of the incidence of Eastern Cooperative Oncology Group (ECOG) deterioration
4. Decrease of the incidence of death
Every parameter will be analysed separately in comparison to historical controls.
In addition a comprehensive immunological monitoring programme is an integrated part of this study. This programme especially focuses on investigations of the induction of anti tumour responses caused by the i.p. immunotherapy with catumaxomab.
Safety parameters like the need to discontinue catumaxomab infusion as well as frequency, relationship and intensity of clinically relevant grade III and IV adverse events will be documented and analysed.

Condition
Peritoneal carcinomatosis from colorectal and gastric cancer (adenocarcinoma)
Intervention
Investigational medicinal product: trifunctional antibody catumaxomab (anti-EpCAM x anti-CD3)
Application of medicinal product: intraperitoneal (i.p.)
Intervention: Laparoscopy or laparotomy and exact staging of peritoneal carcinomatosis will be mandatory. Implantation of an i.p.-port or a catheter-device will be performed. Patients with laparoscopy can be treated with the first dose of catumaxomab after 3 days. Patients with tumor debulking surgery or major resection (anterior rectum resection, gastrectomy) can also be included. In this case, treatment starts at least 10 days after surgery. Further criteria for treatment include complete enteral nutrition and no postoperative problems (i.e. anastomotic leakage, abscess formation etc.). The 1st cycle of catumaxomab is completed by 10-20-50-200 µg on day 0-3-7-10 after start of treatment. Catumaxomab treatment is followed by intravenous chemotherapy within day 30 to 90. A regimen of oxaliplatin, leucovorin, and 5-fluorouracil (FOLFOX4, FOLFOX6, or FOLFIRI) for colorectal and fluorouracil, leucovorin, oxaliplatin (FLO) or fluorouracil, leucovorin, oxaliplatin, and docetaxel (FLOT) for gastric cancer is recommended, but any other chemotherapy according to previous chemotherapy and decision of the medical oncologist is allowed. This is followed by a second cycle of catumaxomab i.p. immunotherapy between day 91 and 120; followed by another i.v.-chemotherapy between day 121 and day 180. Multimodal chemotherapy including biological modifiers (i.e. Cetuximab, Bevacizumab, Trastuzumab or others) is not permitted.
