Study of Fuquinitinib Combined With Capecitabine First-line Maintenance in the Treatment of Metastatic Colorectal Cancer

• Status: Not yet recruiting
• Trial end date: 2026-12-31
• Target enrollment: 0
• Participant gender: All

Summary

This is a single-arm, single-center, prospective phase I/II study that received standard first-line chemotherapy (FOLFOX,FOLFIRI,XELOX, FOLFOXIRI± targeted therapy). If the first-line chemotherapy regimen is a 2-week regimen, patients need to undergo ≥8 cycles of standard chemotherapy. If the first-line chemotherapy regimen is a 3-week regimen, maintenance therapy is required for patients with unresectable advanced metastatic colorectal cancer who have reached CR,PR,SD (RECIST 1.1) after standard chemotherapy after ≥4 cycles.

The eligible patients were screened for maintenance treatment. Maintenance therapy research is divided into the following two phases:

Phase IIB fuquinitinib combined capecitabine dose exploration trial (n=6-9) : Phase II: Dose extension trial (n=47) : 47 patients were continued to be enrolled in the dose extension phase trial according to the recommended dose of fuquinitinib combined with capecitabine established in phase iB, and were treated until toxicity became intolerable or disease progression.

• Phase: N/A

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).

Exclusion Criteria:

2. Participated in other domestic unapproved or unmarketed drug clinical trials and accepted the corresponding experimental drug treatment within 4 weeks before enrollment;

3. Received TACE treatment within 6 weeks before enrollment;

4. Received any surgery or invasive treatment or operation (except intravenous catheterization, puncture drainage, etc.) within 4 weeks before enrollment;

5. International Standardized Ratio (INR) > 1.5 or partially activated prothrombin time (APTT) > 1.5×ULN;

6. The investigator identified clinically significant electrolyte abnormalities;

7. The patient currently has hypertension that cannot be controlled by drugs, as follows: systolic blood pressure ≥140 mmHg and/or diastolic blood pressure ≥90 mmHg;

8. The patient currently has poorly controlled diabetes (fasting glucose concentration ≥CTCAE level 2 after formal treatment);

9. The patient has any current disease or condition that affects drug absorption, or the patient cannot take fuquintinib orally;

10. The patient currently has gastrointestinal diseases such as active gastric and duodenal ulcers, ulcerative colitis, or active bleeding from unresectosed tumors, or other conditions determined by researchers that may cause gastrointestinal bleeding or perforation;

11. Patients with evidence or history of significant bleeding tendency within 3 months prior to enrollment (bleeding within 3 months > 30 mL, hematemesis, stool, stool blood), hemoptysis (within 4 weeks > 5 mL of fresh blood) or had a thromboembolic event (including stroke events and/or transient ischemic attacks) within 12 months;

12. Clinically significant cardiovascular disease, including but not limited to acute myocardial infarction, severe/unstable angina pectoris, or coronary artery bypass grafting within 6 months prior to enrollment; New York Heart Association (NYHA) Grades for Congestive Heart Failure > Level 2; Ventricular arrhythmias requiring medical treatment; LVEF (Left ventricular Ejection Fraction) < 50%;

13. Have had other malignancies within the past 5 years, except basal cell or squamous cell carcinoma of the skin after radical surgery, or carcinoma in situ of the cervix;

14. Active or uncontrolled severe infection (≥CTCAE v5.0 grade 2 infection);

15. Known human immunodeficiency virus (HIV) infection; Known history of clinically significant liver disease, including viral hepatitis [Known hepatitis B virus (HBV) carriers must rule out active HBV infection, i.e., positive HBV DNA (>1×104 copies /mL or > 2000 IU/ml); known hepatitis C virus infection (HCV) and HCV RNA positive (>1×103 copies /mL), or other hepatitis, cirrhosis];

16. The patient has current central nervous system (CNS) metastases or previous brain metastases;

17. Unmitigated toxicity higher than CTCAE v5.0 grade 1 due to any previous anticancer therapy, excluding alopecia, lymphocytopenia, and oxaliplatin grade ≤2 neurotoxicity;

19. Received blood transfusion therapy, blood products and hematopoietic factors, such as albumin and granulocyte colony-stimulating factor (G-CSF), within 14 days before enrollment;

20. Target lesions received brachytherapy (particle implantation) within 60 days before enrollment;

21. Any other medical condition, a clinically significant metabolic abnormality, physical abnormality, or laboratory abnormality that, in the investigator's judgment, reasonably suspects the patient to have a medical condition or condition that is not suitable for the use of the investigational drug (such as the presence of epileptic seizures requiring treatment), or that would affect the interpretation of the study results, or would place the patient at high risk.
