ClinConnect Summary

This clinical trial is investigating a new treatment approach for patients with advanced colorectal cancer that cannot be surgically removed or has spread to other parts of the body. After patients have progressed on a standard first-line treatment called FOLFOXIRI, the study aims to see if a combination of three drugs—fruquintinib, camrelizumab, and capecitabine—can help improve their condition. The researchers hope to find out how effective this combination is in shrinking tumors and extending the time patients live without their cancer getting worse.

To qualify for this study, participants must be at least 18 years old and have been diagnosed with advanced colorectal cancer that has continued to grow despite previous treatments. They should also meet specific health criteria, including stable blood counts and liver and kidney function. If eligible, participants will take the study medications for a set period, and the main goal is to see how well the treatment works and monitor any side effects. It's important to know that this is an open-label study, meaning both the participants and the researchers know which treatments are being given.

Eligibility criteria

• Inclusion Criteria:
• • 1. Metastatic or locally advanced, unresectable colorectal cancer confirmed by histology or cytology
• • 2. The occurrence of metastases after radical resection of colorectal cancer does not require additional histological or cytological confirmation unless more than 5 years since surgery for the primary tumor
• • 3. Progression or toxicity intolerance of first-line treatment with or without targeted drugs (bevacizumab or cetuximab) with FOLFOXIRI regimen or the sequential administration of irinotecan, oxaliplatin, and fluorouracil within a year; if patients with BRAF mutations, who have been treated with BRAF inhibitor alone or in combination with MEK inhibitor also can be included.
• • 4. Target lesion defined by the Response Evaluation Criteria in Solid Tumor (RECIST criteria)
• • 5. Age ≥18 years old, performance status (ECOG) score ≤ 2
• • 6. Estimated expectancy life at least 12 weeks
• 7. Adequate blood, liver and kidney function, as follows:
• • 1. Hemoglobin ≥8g/dl,
• • 2. neutrophil absolute count ≥1000/μL,
• • 3. platelets ≥ 75,000 /μL;
• • 4. Total bilirubin ≤1.5 x upper limit of normal (ULN),

• • 9. Negative pregnancy test within 7 days before enrollment; Pregnancy tests can only be omitted in women who do not have any reproductive potential (e.g., postmenopausal women who had amenorrhea ≥2 years or prior hysterectomy or bilateral oophorectomy). Fertile wo-men and men must consent to the use of appropriate contraception at the time of enrollment and during study participation. If a woman becomes pregnant or suspects that she is pregnant while participating in this study, she must notify her physician immediately; Breastfeeding women must be excluded

• • 11. Have the ability to understand and sign the written informed consent
• Exclusion Criteria:
• • 1. Received antitumor chemotherapy or biotherapy within 28 days prior to the first use of the investigational drug. The exception is a single dose of radiotherapy up to 8Gy for pain relief of non-target lesion during the first 14 days of enrollment
• • 2. Untreated or symptomatic brain metastases

• • 6. Had major surgery (including open biopsy, severe trauma, etc.) within 14 days prior to study enrollment, or expected to require major surgery during the study period, and had minor surgery (excluding Implantable Venous Access Port or peripherally inserted central venous catheter) within 7 days prior to study enrollment
• • 7. Abdominal fistula, gastrointestinal perforation, peptic ulcer or abdominal abscess in the past 6 months
• • 8. Severe, non-healing wounds, ulcers or fractures
• • 9. History of posterior reversible encephalopathy syndrome
• • 10. previous treatment with fruquintinib;
