Summary

Hepatic arterial infuison chemothearpy (HAIC), targeted therapy, and programmed death-1 (PD-1) inhibitors have been demonstrated to be effective for colorectal cancer liver metastasis (CRCLM). Thus, the investigators will conduct a prospective trial to explore the efficacy and safety of targeted treatment based on ctDNA genotyping combined with tislelizumab and HAIC as salvage treatment for advanced CRCLM failed from standard systemic treatment, aiming to provide individualized optimized regimen for microsatellite stable (MSS) CRCLM in salvage treatment.

Detailed description

Although surgery has been demonstrated to improve the prognosis of patients with colorectal cancer liver metastasis (CRCLM), only 20% of patients with CRCLM is candidate for surger. Irinotecan-/oxaliplatin-based doublet/triplet chemotherapy regimen combined with targeted therapy (anti vascular endothelial growth factor \[VEFG\] or anti epidermal growth factor receptor \[EGFR\]) based on the genotype are recommended as standard first- and second-line treatment for unresectabel metastatic colorectal cancer (mCRC) by NCCN guideline. RAS and BRAF are the important signal members in the EGFR signal pathway, and the mutation of them could induce the persistent activation of the downstream of the MAPK pathway, leading to the differentiation, proliferation, and growth change of the tumor cell. The status of RAS and BRAF V600E mutation will affect the efficacy of anti-EGFR therapy, but not anti-VEGF therapy. Regorafenib, fruquintinb, and TAS-102 have been recommended as third-line treatment for mCRC, while the survivl benefits from these agents are limited, with the median progression-free survival (PFS) and median OS of 1.9-3.7 months and 6.4-9.3 months, respectively. The efficacy and safety of hepatic arterial infusion chemotherapy (HAIC) for CRCLM have been demonstrated by multiple trials and recommended by many guidelines worldwide. Fruquintinib, a small molecular tyrosine kinase inhibitor targeting at VEGF 1-3, has been demonstrated to change the tumor microenvironment and enhance the anti-tumor effect of programmed death-1 (PD-1) inhibitor in microsatellite stable (MSS) CRC. Anti-EGFR rechallenge (cetuximab rechallenge) was effective in patients with CRC who interrupted the anti-EGFR therapy while responsed to anti-EGFR therapy in the first-line treatment. In 2021, a phase II trial, which explore the efficacy and safety of cetuximab rechallenge combined with Avelumab for pretreated RAS wide type (WT) mCRC. Our retrospective study (unpublished) showed HAIC combined with fruquintinib and tislelizumab presented greater efficacy for MSS CRCLM. Thus, the investigators will conduct a prospective trial to explore the efficacy and safety of targeted treatment based on ctDNA genotyping combined with tislelizumab and HAIC as salvage treatment for advanced CRCLM failed from standard systemic treatment, aiming to provide individualized optimized regimen for MSS CRCLM in salvage treatment.

Interventions

Type	Name	Description
DRUG	HAIC+targeted therapy+PD-1 inhibitor	HAIC regimen: doublet or triplet regimen based on the response and adverse events occurred in the previous standard treatment (depended on the decision of researchers)-oxaliplatin (85 mg/m2, split into d1 and d2, 0-2h,) and 5-fluorouracial (2g/m2, split into d1 and d2, 2-24h)/ oxaliplatin (65 mg/m2, 0-2h, d1), irinotecan (100 mg/m2, 0-2h, d2), and 5-fluorouracial (2g/m2, split in d1 and d2, 2-24h), repeated every 4 weeks; drug-eluting TACE will be performed at 3rd-4th cycles if the lesions in liver is abundant with blood supply. Tislelizumab (a PD-1 inhibitor): 200 mg, intravenous drip for 30-60 minutes before 24h of HAIC, q4w. Cetuximab (Group A, KRAS/NRAK/BRAF/EGFR wide type and interrupt cetuximab more than 3 months): 500 mg/m2, intravenous drip before HAIC, q4w. Fruquintinib (Group B, KRAS/NRAS/BRAF/EGFR mutation type and wide type but treated with cetuximab in last 3 months): 3 mg/d, d3-23, then suspend for 1w.
