• Conditions: Colorectal Carcinoma

• Registration Number: NCT06115733
• Lead Sponsor: Shanghai General Hospital, Shanghai Jiao Tong University School of Medicine

Brief 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.

Fertile male or female patients volunteered to use effective contraceptive methods, such as double barrier methods, condoms, oral or injectable contraceptives, and Iuds, during the study period and within 6 months of the last study medication. 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

  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;

Group	Intervention	Description
Capecitabine combined with fuquitinib	Fruquintinib、Capecitabine Tablets	Phase Ⅰb dose exploration trial of fuquinitinib combined with capecitabine (n=6-9) : 1. Capecitabine: 1000 mg/m² orally, twice a day on days 1-21 of each cycle, 28 days for one treatment cycle. 2. Fuquinitinib: 1 to 21 days per cycle, orally, once a day, 28 days for a treatment cycle. There are two dose gradients of fuquintinib: 2mg/d, and the initial dose of 3mg/d is 2mg/d. According to the 3+3 dose climbing principle, dose exploration is carried out in the order of 2mg/d→3mg/d, The recommended dose of fuquinitinib combined with capecitabine, as determined in phase I b, continued to enroll 47 patients in the dose-expansion phase trial until the patient became intolerant of toxicity or disease progression.
