Immunoscore As Decision Guidance for Adjuvant Chemotherapy in Colon Cancer (iMAGINE)

IMmunoscore Associated Decision GuIdance for AdjuvaNt Chemotherapy and Physical Exercise in Stage III Colon Cancer (iMAGINE): a Prospective, Randomized, Open-label, Multicenter, Phase III Clinical Trial

The overall aim of this study is to prospectively validate the superiority of the Immunoscore as a decision guidance for adjuvant chemotherapy in stage III colon cancer patients, in comparison to the conventional TNM-based high- or low-risk classification.

Arms and Interventions

Participant Group / Arm	Intervention / Treatment
Experimental: Immunoscore stratification; Immunoscore low (I-Low; I0-1): 3 months CAPOX (oxaliplatin 130 mg/m2 IV over 2 h and capecitabine 1000 mg/m2 PO twice daily (days 1-14). 21-day treatment cycle.). Concomitantly, standardised physical excise (stair walking excise twice a week for 12 weeks), which will be monitored by an electronic sports device.; Immunoscore intermediate-high (I-IntHi; I2-3): 6 months FOLFOX (oxaliplatin 85 mg/m2 IV (on day 1) and folinic acid 200 mg/m2 IV over 2 h, followed by a bolus of fluorouracil 400 mg/m2 IV over 2-4 min, followed by fluorouracil 600 mg/m2 IV over 22 h (for 2 consecutive days). 14-day treatment cycle.); Immunoscore high (I high; I4): no adjuvant treatment.	Drug: Capecitabine; Tablet; Drug: Oxaliplatin; Infusion; Drug: Fluorouracil; Infusion; Drug: Leucovorin; Infusion; Device: Immunoscore® assay; Whole-slide tissue analysis of CD3+ and cytotoxic CD8+ T cells in the tumor and in the invasive margin; Other: Physical exercise; Increasing stair walking exercise twice a week over 12 weeks total.
Active Comparator: TNM stratification; TNM-based low-risk (pT1, pT2 or pT3 and pN1): 3 months CAPOX (oxaliplatin 130 mg/m2 IV over 2 h and capecitabine 1000 mg/m2 PO twice daily (days 1-14). 21-day treatment cycle.); TNM-based high-risk (pT4 and/or pN2): 6 months FOLFOX (oxaliplatin 85 mg/m2 IV (on day 1) and folinic acid 200 mg/m2 IV over 2 h, followed by a bolus of fluorouracil 400 mg/m2 IV over 2-4 min, followed by fluorouracil 600 mg/m2 IV over 22 h (for 2 consecutive days). 14-day treatment cycle.)	Drug: Capecitabine; Tablet; Drug: Oxaliplatin; Infusion; Drug: Fluorouracil; Infusion; Drug: Leucovorin; Infusion
