Results reported by the registry submitting party. Population, time horizon, units and missing values must be read together.

Measure: NUMBER
Unit: percent probability
Interval / dispersion: 95% Confidence Interval
Time frame: From baseline, at peritoneal disease relapse from Complete Response (CR) or peritoneal disease progression, and after completion of therapy up to a percent probability of PFS at 12 months

What was measured

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.

Analysis population: 7/21 participants were analyzed because 12 participants were not treated and 2 refused further treatment. In this table, there are 0 participants analyzed in the 1st, 2nd, 3rd, and 4th groups/columns because there were no Colorectal participants in those groups. That is the case for the other histologies as well.

Groups in this outcome

Intravenous Paclitaxel Dose Level 1, Intraperitoneal Paclitaxel Dose Level 1, Nilotinib Dose Level 1

Ended treatment at the regular dose level: 80 intravenous (IV)/80 Intraperitoneal (IP) + 300 twice a day (BID).

Intravenous Paclitaxel DoseLevel -1, Intraperitoneal Paclitaxel Dose Level 1, Nilotinib Dose Level 1

Had the planned doses for Intraperitoneal (IP) Paclitaxel (80 IP) and by mouth (PO) nilotinib (300 twice a day (BID) but declined to go up to the 80mg/m\^2 of intravenous (IV) Paclitaxel.

Intravenous Paclitaxel DoseLevel 1, Intraperitoneal Paclitaxel Dose Level 1, Nilotinib Dose Level -1

Had the planned doses for intravenous (IV) and Intraperitoneal (IP) Paclitaxel (80 IV/80 IP) but had a dose reduction for Nilotinib (400 every day (QD).

Intravenous Paclitaxel DoseLevel -1, Intraperitoneal Paclitaxel DoseLevel 1, Nilotinib Dose Level -1

Had the planned dose of Intraperitoneal (IP) Paclitaxel (80 IP) but had a dose reduction for intravenous (IV) Paclitaxel (60 IV), and a dose reduction for Nilotinib (400 every day (QD).
