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.

Arms and Interventions
Participant Group / Arm |
Intervention / Treatment |
---|---|
Active Comparator: Upfront repeat local treatment
|
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). |
Experimental: Neoadjuvant systemic therapy followed by repeat local treatment
|
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). 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 |
What is the study measuring?
Primary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Overall survival (OS) per patient
Time Frame: 5 years
|
Primary objective is to compare overall survival (OS) in both study arms, counting from the date of randomization to the date of death of the patient or to the last day of follow-up (censored).
|
5 years
|
Secondary Outcome Measures
Outcome Measure |
Measure Description |
Time Frame |
---|---|---|
Distant progression-free survival (DPFS) per patient
Time Frame: 5 years
|
Distant progression free survival (DPFS; per patient analysis): Overall DPFS is defined as the time from randomization to the time of disease progression (according to the RECIST 1.1 guideline) or cancer related death (events), death related to other causes is considered a competing risk
|
5 years
|
Local tumor progression-free survival (LTPFS) per patient and per tumor treated
Time Frame: 5 years
|
Local tumor progression free survival (LTPFS; per tumor and per patient analysis): Overall LTPFS is defined as the time from randomization to the time of local disease progression, new metastases (events), censoring the date of death from any cause (competing risk), completion ablations performed within 6 weeks for residual tumor are not considered events for the local tumor progression analysis
