Actual (reported)Patients primary malignant peritoneal mesothelioma (MPM), without extra-abdominal disease, that are not eligible (or willing) to undergo cytoreductive surgery (CRS) with hyperthermic intraperitoneal chemotherapy (HIPEC) can be included in this study. Patients will be treated with intraperitoneal (IP) chemotherapy (paclitaxel) in weekly cycles. The primary aim of this study is to determine the maximum tolerable dose (MTD) of IP monotherapy with paclitaxel for patients with MPM. The secondary aims are to assess safety and feasibility of this strategy, and to study the pharmacokinetics of paclitaxel in this setting.

Actual (reported)The maximum tolerable dose (MTD)
The primary endpoint of the study is to determine the maximum tolerable dose (MTD) of intraperitoneal (IP) paclitaxel monotherapy, for patients with malignant peritoneal mesothelioma (MPM) who are not eligible to undergo CRS-HIPEC.
Week 3 (after two completed cycles of therapy, each cycle is 1 week)
Toxicity assessment
Week 3 (after two completed cycles of therapy, each cycle is 1 week)
Feasibility determined by the number of cycles given
Week 8 (after eight completed cycles of therapy, each cycle is 1 week)
Area Under the Curve (AUC)
At cycle 1 and 4 (each cycle is 1 week)
Maximum concentration (Cmax)
At cycle 1 and 4 (each cycle is 1 week)
Elimination half life (t1/2)
At cycle 1 and 4 (each cycle is 1 week)
According to standard of care work-up for CRS-HIPEC, patients will undergo diagnostic laparoscopy to determine the feasibility of complete cytoreduction with HIPEC. In case CRS-HIPEC is not considered feasible, a peritoneal port-a-cath (PAC) system will be placed. Through this PAC, 8-16 weekly cycles of intraperitoneal chemotherapy will be administered.
Weekly cycles of intraperitoneal paclitaxel monotherapy
