Advanced Colorectal Cancer
Conditions
Brief summary
To explore the efficacy and safety of fruquintinib combined with chemotherapy as third-line/third-line+ Treatment in advanced metastatic colorectal cancer
Detailed description
Due to the limited efficacy of third-line treatment, the previously effective chemotherapy regimen is a new treatment mode. RE-OPEN, RE-OX and a Korean study confirmed that mCRC patients who had previously been effectively treated with oxaliplatin were retreated with oxaliplatin on the third line to help them achieve OS for 14.5 to 18.5 months. At the same time, a phase III randomized SUNLIGHT study showed good efficacy at the ASCO-GI Congress in 2023. The above studies show that the regimen of antivascular drugs combined with chemotherapy has a tendency to improve the survival of patients with third-line advanced colorectal cancer. In order to further improve the efficacy of fruquintinib, we conducted a clinical study of fruquintinib combined with chemotherapy to observe the efficacy and safety of Third-line/Third-line+ treatment of advanced colorectal cancer, and to provide a more effective treatment plan for third-line and above treatment for advanced colorectal cancer patients.
Interventions
1.Security introduction period: \[1\] Safety introduction period (N=6), fruquintinib combined with three-week regimen: 1\. Fruquintinib: Three-week regimen of combined chemotherapy: 4mg/d, orally, once a day, taking the drug for 2 weeks and stopping the drug for 1 week, 3 weeks as a treatment cycle. \[2\] Safety introduction period (N=6), fruquintinib combined 2-week regimen: 1. Fruquintinib: two-week combination chemotherapy regimen: 4mg/d, orally, once a day, taking the drug for 3 weeks and stopping the drug for 1 week, 4 weeks as a treatment cycle. 2. Dose expansion phase design(N=60) Cohort 1 (30 patients) : Fruquintinib combined with oxaliplatin. Cohort 2 (30 patients) : Fruquintinib combined with irinotecan .

Inclusion criteria
1. Have fully understood the study and voluntarily signed the informed consent 2. Age ≥18 years old, male or female 3. Advanced metastatic colorectal adenocarcinoma confirmed by histopathology 4. The best efficacy evaluation of first-line chemotherapy (mFOLFOX6, XELOX, or FOLFIRI) in previous patients must be partial response (PR) or above or progression-free survival (PFS) ≥1 year, with a first-line drug withdrawal interval of more than 1 year. Pre-adjuvant/neoadjuvant therapy is allowed. If recurrence or metastasis occurs during or within 6 months after completion of adjuvant/neoadjuvant therapy, adjuvant/neoadjuvant therapy is considered a failure of first-line chemotherapy for advanced disease 5. The patient has failed at least previous second-line treatment，The use of Cetuximab (KRAS and Braf wild type) and bevacizumab in previous anti-tumor regiments is required，Prior treatment with regorafenib or TAS-102 is permitted 6. ECOG status 0-2 points 7. Expected survival ≥12 weeks 8. Have at least one measurable lesion (RECIST version 1.1) 9. Inadequate bone marrow reserve or organ function, as demonstrated by any of the following laboratory values: Absolute neutrophil count (ANC) ≥1.5×109/L Platelet count ≥80×109 / L Hemoglobin≥80 g/L（\<8 g/dL） Serum albumin ≥3g/dL Alanine aminotransferase \<2.5 × upper limit of normal (ULN) if no demonstrable liver metastases or \<5 × ULN in the presence of liver metastases. Aspartate aminotransferase (AST) \<2.5 × ULN if no demonstrable liver metastases or \< 5 × ULN in the presence of liver metastases. Total bilirubin (TBL)\<1.5 × ULN Creatinine≤ 1.5 × ULN concurrent with creatinine clearance ≤50 mL/min (measured or calculated by the Cockcroft-Gault equation) confirmation of creatinine clearance is only required when creatinine is ≤1.5 × ULN. 10. Fertile male or female patients voluntarily used effective contraceptive methods, such as double barrier methods, condoms, oral or injectable contraceptives, intrauterine devices, etc., during the study period and within 6 months of the last study dose. All female patients will be considered fertile unless they have undergone natural menopause, artificial menopause, or sterilization (such as hysterectomy, bilateral adnexectomy, or irradiation of radioactive ovaries). 11. Good compliance, cooperate with follow-up.
Exclusion criteria
