Masking: None (Open Label)

Intervention:

Intervention type: Drug
Intervention name: Neoadjuvant systemic therapy (CAPOX+/-B FOLFOX+/-B FOLFIRI+/-B)
Description: Standard first line systemic treatment: CAPOX+/-B FOLFOX+/-B FOLFIRI+/-B CAPOX 4x (12 weeks) FOLFOX/FOLFIRI 6x (12 weeks) Maximum 4 cycles of CAPOX or 6 cycles of FOLFOX/FOLFIRI +/- bevacizumab regardless of the location of primary tumor or RAS/BRAF mutation
Arm group label: Neoadjuvant systemic therapy followed by repeat local treatment

Intervention type: Other
Intervention name: Repeat local treatment
Description: Choice of repeat local treatment is to the discretion of the local investigator, and may be selected on a per patient basis. The safety, feasibility and preferred type of surgical resection(s) is at the discretion of the liver surgeon (whether or not combined with thermal ablation). The safety, feasibility and preferred type of thermal ablation(s) is at the discretion of the interventional radiologist (whether or not combined with surgical resection).
Arm group label: Neoadjuvant systemic therapy followed by repeat local treatment
Arm group label: Upfront repeat local treatment

Summary: The primary objective is to demonstrate superiority of neoadjuvant systemic therapy followed by repeat local treatment as compared to upfront repeat local treatment in patients with at least one locally treatable recurrent CRLM in the absence of extrahepatic disease.

Detailed description: Study design: The COLLISION RELAPSE trial is a prospective multicenter phase III randomized controlled trial. The primary conducting center will be the Amsterdam UMC (Amsterdam, the Netherlands). We hypothesize that neoadjuvant systemic therapy followed by repeat local treatment is superior to upfront repeat local treatment for the selected patient groups in terms of the primary objective (OS). The Cox proportional hazards model (1-sided; superiority) and the PASKWIL criteria for adjuvant treatment for the benefit of OS from the Dutch Society of Medical Oncology are used for the sample size calculations. A total number of 360 patients will be randomized (NR) into one of two arms: arm A (control group) upfront repeat local treatment (n=180) and arm B (intervention group) 12 weeks of neoadjuvant systemic therapy followed by repeat local treatment (n=180). Study population: Patients with a maximum of 5 recurrent new locally treatable CRLM within 12 months after initial curative intent local treatment of CRLM, no extrahepatic disease, and a good performance status (ECOG 0-2) are considered eligible. Both chemo-naïve patients and patients who did not progress on either oxaliplatin or irinotecan chemotherapy prior to the initial local treatment are eligible for inclusion. Eligible patients will be stratified before randomization into two groups depending on the interval between initial local treatment and first detection of recurrent CRLM: recurrence within 6 months and recurrence between 6 and 12 months, RAS/BRAF mutation vs RAS/BRAF wildtype, prognostic risk score (low vs high risk, clinical risk score Fong et al. (83)) and previous chemotherapy versus no previous chemotherapy. Intervention: Eligible patients will be randomized into one of two arms: arm A (control group) upfront repeat local treatment and arm B (intervention group) 12 weeks of neoadjuvant systemic therapy followed by repeat local treatment. Patients in arm B will receive maximum 4 cycles of CAPOX or 6 cycles of FOLFOX/FOLFIRI +/- bevacizumab regardless of the location of primary tumor or RAS/BRAF mutation. Choice of repeat local treatment is to the discretion of the local investigator, and may be selected on a per patient basis.
