The FIRE-4 study aims to define a treatment concept for patients with RAS wild-type tumours, optimised with regard to overall survival. The first-line treatment will be conducted with FOLFIRI plus cetuximab, which resulted in a significantly prolonged overall survival versus bevacizumab in the FIRE-3 study. Following initial progression (PD1) it is recommended that the treatment be continued with FOLFOX plus bevacizumab, as this concept led to significantly prolonged survival in the E3200 study. Owing to the encouraging results of the Santini study , a cetuximab rechallenge in combination with irinotecan-based chemotherapy is to be performed as part of the third-line treatment in patients who showed a response defined according to RECIST 1.1 during the first-line treatment (tumour diameter < -30%) or presented with stable tumour disease for at least 6 months (tumour diameter +20 to -30%). The concept of the ideal sequence has not yet been studied to date in a clinical trial.
The study will begin with FPFV: (first study visit of the first patient, signing the declaration of consent to participate in the study): scheduled for the 4th quarter of 2014
Patient recruitment: 36 months
Treatment duration per patient: Until the time of progression under the third-line treatment at the latest. Anticipated individual duration of treatment: 24 months (for patients who undergo all three treatment lines -included in part 1), or 6 months in patients who only receive third line treatment (included directly in part 2)
Duration of follow-up after the end of treatment: For all patients, until death or for at least 1 year following final termination of any study treatment regardless of the treatment line. In so doing, the follow-up period for patients included in part 1 of the study will be conducted for a maximum of 5 years from the time of randomisation 1; and for patients included in only part 2 of the study (third-line treatment), for a maximum of 3 years from the date of randomisation 2.
End of the study: last follow-up visit of the last study patient scheduled for the 4th quarter of 2020

The FIRE-3 trial is a multicenter randomized phase III trial investigating 5-FU, folinic acid and irinotecan (FOLFIRI) plus cetuximab versus FOLFIRI plus bevacizumab in first line treatmen...
This phase II study will evaluate which is the best way to administer cetuximab after recurrence in 1st line irinotecan+bevacizumab based treatment and to obtain results of the efficacy of...
The goal of this clinical research study is to learn the highest tolerable dose of irinotecan that can be given directly into the liver, in combination with other drugs given by vein. ...
This study is being performed to test if the use of high dose of cetuximab in combination with irinotecan overcomes the resistance seen with standard dose of cetuximab plus irinotecan in p...
RATIONALE: Drugs used in chemotherapy, such as irinotecan, work in different ways to stop the growth of tumor cells, either by killing the cells or by stopping them from dividing. Monoclon...
Fluorouracil and folinic acid with irinotecan (FOLFIRI) plus bevacizumab (BV) is widely used as second-line chemotherapy for patients with metastatic colorectal cancer (mCRC) previously treated with f...
Acquired drug resistance to the chemotherapeutic drug irinotecan (the active metabolite of which is SN-38) is one of the significant obstacles in the treatment of advanced colorectal cancer (CRC). The...
Treatment sequence with either irinotecan/cetuximab followed by FOLFOX-4 or the reverse strategy in metastatic colorectal cancer patients progressing after first-line FOLFIRI/bevacizumab: An Italian Group for the Study of Gastrointestinal Cancer phase III, randomised trial comparing two sequences of therapy in colorectal metastatic patients.
The optimal treatment strategy for RAS wild type (WT) mCRC is controversial. Our phase III study investigated the effect of introducing earlier (second-line) or later (third-line) cetuximab in patient...
Diversity in colorectal cancer biology is associated with variable responses to standard chemotherapy. We aimed to identify and validate DNA hypermethylated genes as predictive biomarkers for irinotec...
The aim of this study was to evaluate the efficacy and safety of combining irinotecan, bevacizumab, and cetuximab/panitumumab as a 4th-line treatment in patients with metastatic colorectal cancer.
