Tumors that have spread to the lining of the abdomen from other cancers, such as cancer of the appendix, colon, or ovary, are called peritoneal carcinomatosis. In most cases, outcomes are poor. Researchers want to test a new treatment.
To learn if the combination of oral nilotinib plus paclitaxel given by IV and directly into the abdomen can reduce tumors enough for people to have surgery.
Adults aged 18 and older with peritoneal carcinomatosis that is too widespread for surgery.
Participants will be screened with:
Blood and urine tests
Laparoscopy. They will get general anesthesia. Small cuts will be made in their abdomen. Tissue and fluid samples will be taken.
Surveys about their health
CT scans of their torso
Participants will have up to 4 more laparoscopies. During the first procedure, a port will be placed under the skin of their abdomen (an IP port). It will be attached to a catheter that is placed in their abdomen.
Participants will get treatment in 3-week cycles, for 3 or 6 cycles. They will take nilotinib by mouth twice daily. They will get paclitaxel by IP port (once per cycle) and by IV (twice per cycle). After cycles 3 and 6, they will have a laparoscopy and CT scans. Then they may take nilotinib and get IV paclitaxel for up to 1 year.
At study visits, participants will repeat some screening tests.
About 6 weeks after treatment ends and then every 3 months for 3 years, participants will have follow-up visits at NIH or with their local doctor.
