A Dose Escalation Study of MM-398 Plus Irinotecan in Patients With Unresectable Advanced Cancer

Phase 1
Completed
Conditions
Unresectable Advanced Cancer
Interventions
Drug: MM-398
Drug: Irinotecan
Drug: Leucovorin (LV)
Drug: 5-fluorouracile (5-FU)
Drug: bevacizumab
Registration Number
NCT02640365
Lead Sponsor
GERCOR - Multidisciplinary Oncology Cooperative Group
Brief Summary

MM-398 (also known as PEP02) is nanoliposomal encapsulated irinotecan: the liposomal formulation is designed to extend plasma circulation and to increase accumulation in the tumor through the enhanced permeability and retention (EPR) effect.

This study introduces a new concept of combining free and nanoliposomal drugs.

Detailed Description

This is a dose-finding and therapeutic exploratory phase Ib multi-center, open label study of MM-398 plus irinotecan in two different settings:

* Group A : patients with unresectable advanced non-colorectal cancer who should receive only MM-398 and irinotecan

* Group B : patients with unresectable metastatic colorectal cancer who should receive MM-398 and irinotecan combined with leucovorin, 5-fluorouracil and bevacizumab.

These groups will be enrolling in parallel. Pharmacokinetic and biomarker sampling will also be performed.

There are three periods to this study :

Screening period (up to -28d): patients undergo screening assessments to determine the eligibility for the study

MM-398 treatment period (C1D1 until safety evaluation/progression): patients receive treatment every 2 weeks and undergo biopsies and other required assessments. The treatment period is divided into a maximum of 3 dose levels

Follow up period: patients will be followed-up 30 days after their last dose of MM-398 for final safety assessments, and every 2 months thereafter for overall survival follow-up
