Intravenous and Intraperitoneal Paclitaxel and Oral Nilotinib for Peritoneal Carcinomatosis

Found through the registry condition index, not selected as a treatment recommendation. This discovery collection was restricted to studies with posted results.

Phase: PHASE2
Status at capture: COMPLETED
Registry last update: 2026-06-25

Background: 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. Objective: To learn if the combination of oral nilotinib plus paclitaxel given by intravenous (IV) and directly into the abdomen can reduce tumors enough for people to have surgery. Eligibility: Adults aged 18 and older with peritoneal carcinomatosis that is too widespread for surgery. Design: Participants will be screened with: Physical exam Medical history Blood and urine tests Electrocardiogram 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 Computed tomography (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 intraperitoneal (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 National Institutes of Health (NIH) or with their local doctor.

description
Here is the number of participants with serious and/or non-serious adverse events assessed by the Common Terminology Criteria for Adverse Events (CTCAE v5.0). A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned.

primary Outcomes

description
We calculated the rate of downstaging of peritoneal disease burden to become resectable based on PCI score of initial and subsequent laparoscopy, or magnetic resonance imaging and/or computed tomography imaging if laparoscopy is not planned. Disease burden will be considered stable when PCI score at laparoscopy (lap) #3 is \< 4 points higher or lower compared to PCI score at lap #2. Complete Response is PCI≤ 5 with negative histology of at least 3 peritoneal biopsies of suspect nodules and washings with negative cytology. Partial Response (PR) is at least 4 points decrease in PCI. Progressive Disease (PD) has at least 4 points increase in PCI. Stable Disease is neither sufficient shrinkage to qualify for PR nor sufficient increase to qualify for PD, taking as reference the PCI. To document PCI scoring for each participant, the rubric will be completed following each laparoscopy. The PCI is scaled from 0-39, with higher scores indicating higher disease burden and worse prognosis.

description
The proportion of participants who are successfully down-staged to resectable by use of chemotherapy will be reported along with a 95% confidence interval. This outcome measure evaluates how many participants with initially inoperable (unresectable) peritoneal carcinomatosis became eligible for surgery after receiving bidirectional chemotherapy (intravenous and intraperitoneal paclitaxel and oral nilotinib).

description
Percent pPFS will be reported using the Kaplan-Meier method, along with a 95% confidence interval for each histology. PFS is defined as the duration of time from the start of the treatment until time of peritoneal disease relapse from Complete Response (CR) or peritoneal disease progression, or death, whichever comes first, and after completion of therapy. Response was assessed by the Peritoneal Carcinomatosis Index (PCI) and the Response Evaluation Criteria in Solid Tumors (RECIST). Disease relapse is CR is PCI≤ 5 with negative histology of at least 3 peritoneal biopsies of suspect nodules and washings with negative cytology. Disease progression is at least 4 points increase in PCI. The appearance of one or more new lesions is also considered progressions. The Kaplan-Meier method calculates a survival function S(t), which represents the probability of "surviving" (remaining event-free) beyond time t. It is not calculated directly as a percentage.

Safety will be assessed by analyzing the type, grade and frequency of toxicities. Adverse events (AEs) will be assessed using CTCAE v.5.0. A non-serious adverse event is any untoward medical occurrence. A serious adverse event is an adverse event or suspected adverse reaction that results in death, a life-threatening adverse drug experience, hospitalization, disruption of the ability to conduct normal life functions, congenital anomaly/birth defect or important medical events that jeopardize the patient or subject and may require medical or surgical intervention to prevent one of the previous outcomes mentioned. Grade 1 is mild. Grade 2 is moderate. Grade 3 is severe. Grade 4 is life-threatening. Grade 5 is death related to adverse event.

Outcomes from QOL comparing results before to after treatment: Quality of life is assessed using the Functional Assessment of Cancer Therapy - Colorectal (FACT-C) questionnaire, a validated instrument that measures health-related quality of life. The FACT-C consists of the following subscales: Physical Well-Being (PWB): 7 items; score range 0-28, Social/Family Well-Being (SWB): 7 items; score range 0-28, Emotional Well-Being (EWB): 6 items; score range 0-24, Functional Well-Being (FWB): 7 items; score range 0-28, Colorectal Cancer Subscale (CCS):9 items; score range 0-36.The FACT-C total score is derived by summing all five subscale scores. Total score range: 0-144. For all subscales and the total score, higher values represent better quality of life and lower values represent worse quality of life. Questionnaires are administered at baseline, immediately prior to treatment Cycles 3 and 6, and at follow-up visits. A single value (average) was calculated for "during treatment immediate

detailed Description: Background: * Peritoneal carcinomatosis is uniformly fatal if untreated; despite advances in systemic chemotherapy, cytoreductive surgery, and intraperitoneal chemotherapy, survival remains poor for the majority of patients * The combination of oral nilotinib and intravenous paclitaxel has demonstrated pre-clinical and clinical synergism in the treatment of solid tumors, with an ongoing Phase I trial at the National Institutes of Health (NIH) * The synergy of oral nilotinib with intraperitoneal paclitaxel remains to be characterized * This study involves the combination of intravenous and intraperitoneal paclitaxel and oral nilotinib for unresectable peritoneal carcinomatosis from colorectal, appendiceal, small bowel, gastric, cholangiocarcinoma, breast, ovarian, or other gynecologic primary histologies. Objective: -To evaluate efficacy of bidirectional chemotherapy using intraperitoneal and intravenous paclitaxel and oral nilotinib by calculating the rate of downstaging of peritoneal disease burden to become resectable, based on Peritoneal Carcinomatosis Index (PCI) Eligibility: * Participants \>= 18 years of age with histologically confirmed peritoneal carcinomatosis of colorectal, appendiceal, small bowel, gastric, cholangiocarcinoma, breast, ovarian, or other gynecologic primary histology * Demonstrated resistance or lack of response to at least one line of already approved and available systemic chemotherapy * No history of allergic reactions attributed to compounds of similar chemical or biologic composition to study drugs * No intraperitoneal chemotherapy within the last six months * Deemed unable to undergo complete cytoreduction Design: * Phase II open-label, non-randomized study * After confirmation of eligibility, at the time of diagnostic laparoscopy, biopsies will be taken, and an intraperitoneal catheter will be placed for subsequent chemotherapy administration * Up to 6 cycles will be planned, with restaging laparoscopy and biopsies after Cycles 3 and 6
