Summary

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.

Description

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

Eligibility

Yes No Not Sure

Inclusion Criteria

Histologically confirmed, UICC stage IV adenocarcinoma of the colon or rectum (metastatic colorectal cancer), primarily nonresectable or with surgery refused by the patient

Primary tumour tissue available and patient consents to storage and molecular and genetic profiling of blood, plasma and tumour material (patients included directly at Part 2 of the study in whom primary tumour material is no longer available may be included in the study, provided that tumour material from the compulsory biopsy on progression following second-line treatment is available)

Adequate hepatic function
Serum bilirubin 1.5 x upper normal limit
ALAT and ASAT 2.5 x upper normal limit (in the presence of hepatic metastases, ALAT and ASAT 5 x upper normal limit)
INR < 1.5 and aPTT < 1.5 x upper normal limit (patients without anticoagulation). Therapeutic anticoagulation is allowed if INR and aPTT have remained stable within the therapeutic range for at least 2 weeks

Last administration of an anti-EGFR substance 4 months before randomisation 2
Inclusion criterion solely for Part 1
No previous chemotherapy for metastatic disease
Time since last administration of a previous adjuvant chemotherapy >6 months
Additional inclusion criteria solely for Part 2
Former first-line treatment of the metastatic colorectal cancer with FOLFIRI and cetuximab; data available for the duration of treatment and the response within the context of first-line treatment
Former second-line treatment of the colorectal cancer without FOLFIRI, irinotecan or an anti-EGFR substance with data available for the substances administered, duration of treatment and response within the context of the second-line treatment
Proof of a RAS wild-type tumour (KRAS and NRAS exons 2-4) in a tumour biopsy (metastasis) within 4 weeks before randomisation
CT examinations with evidence of a partial response (PR) or complete response (CR) or stable disease (SD) 6 months according to RECIST Version 1.1 criteria as best response within the context of the first-line treatment with FOLFIRI and cetuximab

Exclusion Criteria
