Basic Information

• Recruitment Status: UNKNOWN
• Clinical Phase: PHASE2
• Total Enrollment: 68 participants
• Study Classification: INTERVENTIONAL
• Study Start Date: 2021-08-23
• Study Completion Date: 2023-12-31

Brief Summary

This is a prospective, single-center, single-arm phase II clinical trial.This study aims to evaluate the safety and tolerability of stereotactic ablative radiotherapy (SABR) in combination with Fruquintinib and Tislelizumab, and to examine the impact of the combination therapy on tumor control, long-term survival and quality of life in patients with Metastatic colorectal cancer.

A total of 68 metastatic colorectal cancer patients who have failed the first-line standard treatment, will be recruited and receive multisite SABR(8-12 Gy, 4-5 times) followed by fruquintinib(5mg, qd) and tislelizumab(200mg, q3w) within two weeks from completion.The overall response rate (ORR), disease control rate(DCR), progression-free survival(PFS) and overall survival(OS) will be analyzed.

• Intervention Model: SINGLE_GROUP
• Primary Study Purpose: TREATMENT
• Blinding Strategy: NONE

Study Groups

Treatment Arm

A total of 68 metastatic colorectal cancer patients who have failed the first-line standard treatment will receive multisite SABR followed by Fruquintinib and Tislelizumab within two weeks from completion.

The dosing of Tislelizumab will continue for up to two years until disease progression, unacceptable toxicity or patient withdrawal.

Group Type: EXPERIMENTAL

Stereotactic Ablative Radiotherapy (SABR)

Intervention Type: RADIATION

We plan to irradiate as many metastatic lesions as possible, in the precondition that normal tissues can tolerate.

Target dose will be adjusted depending on site of the lesion and organs at risk (BED > 100Gy).

Treatment schedule is once per day and five days per week. Sequence of irradiation for multiple metastases is at the discretion of the investigators based on their experience.

Fruquintinib

Intervention Type: DRUG

Starts within two weeks upon SABR completion: 5mg, d1-14, qd; Continued until disease progression, unacceptable toxicity or patient withdrawal.

Tislelizumab

Intervention Type: DRUG

Starts within one week upon SABR completion: 200mg, d1, q3w; the dosing will continue for up to two years until disease progression, unacceptable toxicity or patient withdrawal.
