Phase I/II Study to Evaluate Nab-paclitaxel in Substitution of CPT11 or Oxaliplatin in FOLFIRINOX Schedule as First Line Treatment in Metastatic Pancreatic Cancer

NCT ID: NCT02109341

Last Updated: 2017-02-03

Basic Information

• Recruitment Status: COMPLETED
• Clinical Phase: PHASE1/PHASE2
• Total Enrollment: 148 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2014-02-28
• Study Completion Date: 2016-01-31

Brief Summary

At this moment, FOLFIRINOX is the best treatment for selected patients (pts) with metastatic pancreatic cancer (mPC). Investigator would like to evaluate the substitution of CPT11 or Oxaliplatin in FOLFIRINOX schedule with Nab-paclitaxel (Nab-p) [Nab-FOLFIRI and Nab-FOLFOX].

Doses for Nab-FOLFIRI and Nab-FOLFOX will be determined by the phase I trial. One or both schedules will be evaluated in successive phase II part.

Detailed Description

The primary objective for phase I of the study is to determine the MTD of Nab-p when used in substitution of OXA or CPT11 in FOLFIRINOX schedule, as first-line treatment in pts with mPC. The dose finding strategy will be based on the classical 3+3 dose escalation design.

-Analysis sets: Modified intention-to-treat population: it consists of all pts who are allocated and receive at least one dose of any component of study treatment. Pts will be grouped according to the randomized treatment assignment. Pts treated during the phase I step will be not included in this population.

Safety population: it consists of all pts who are allocated and receive at least one dose of any component of study treatment. Groups are defined by the study treatment actually received. Pts treated at the MTD during the phase I step will be not included in this population.

Statistical methods Best ORR will be summarized and 95% confidence limits will be calculated according to the exact method for each of the treatment arms included in the phase II step.

All the analyses of primary and secondary efficacy variables will be performed on the modified intention-to-treat population.

The overall incidences of AEs will be summarized. Pts who experienced the same event on more than one occasion are counted only once in the calculation of the event frequency, at the highest intensity ever observed.

Serious adverse events will be summarized. All the safety analyses will be performed on the safety population.

-Sample size: The experimental treatment, to be considered clinically worthwhile, should determine an overall best RR equal to or greater than 40%. According to the Fleming single stage design, for a 90% power towards an alternative hypothesis of an ORR equal to or greater than 40% and a one-sided type I error rate of 5%, respect to the null hypothesis of an ORR equal to or less than 20%, 42 pts must be included in the final evaluation, in each arm of the phase II step. According to the exact binomial test, the experimental treatment will be considered sufficiently promising and candidate to further studies in the case of a major objective response is seen in at least 14 pts.

Study Groups

Nab-FOLFIRI

In the phase I study, all pts enrolled in this arm will receive Nab-FOLFIRI: Irinotecan, 180 mg per square meter of body surface area (m2 ) + Leucovorin, 400 mg/m2 and 5-Fluorouracil, 400 mg/m2 given as a bolus followed by 2400 mg/m2 given as a 46-hour continuous infusion, plus Nab-p per cohort escalation assignment starting with 90 mg/m2 every 2 weeks. Pts continued treatment until a total of 12 administrations, disease progression or unacceptable toxicity.

Pts enrolled in arm A for phase II will receive the dose of Nab-FOLFIRI as determined in the Phase I and in the same sequence.

Group Type: EXPERIMENTAL

Paclitaxel bound albumine

Intervention Type: DRUG

Nab-FOLFOX

In the phase I study, all pts enrolled in this arm will receive Nab-FOLFOX: Oxaliplatin 85 mg/m2 +Leucovorin, 400 mg/m2 and 5-Fluorouracil, 400 mg/m2 given as a bolus followed by 2400 mg/m2 given as a 46-hour continuous infusion, plus Nab-p per cohort escalation assignment starting with 90 mg/m2, every 2 weeks.

Pts continued treatment until a total of 12 administrations, disease progression or unacceptable toxicity.

Pts enrolled in arm B for phase II will receive the dose of Nab-FOLFOX as determined in the Phase I and in the same sequence
