Radiotherapy Combined QL1706, TAS-102 and Bevacizumab in mCRC

August 6, 2025 updated by: Meili Sun, Jinan Central Hospital

A Single-Arm, Exploratory Study of Palliative Radiotherapy Combined With Iparomlimab and Tuvonralimab, Trifluridine/Tipiracil (TAS-102), and Bevacizumab in Later-Line Treatment of Advanced Colorectal Cancer

This single-center, single-arm, prospective study plans to enroll patients with advanced colorectal cancer who have failed first-line or higher systemic therapies. Participants will receive a combination of iparomlimab and tuvonralimab (QL1706), trifluridine/tipiracil (TAS-102), bevacizumab, and palliative radiotherapy. The efficacy and safety of this combination therapy will be evaluated by assessing objective response rate (ORR), progression-free survival (PFS), overall survival (OS), disease control rate (DCR), and safety profile.

Phase

Phase

The stage of a clinical trial studying a drug or biological product, based on definitions developed by the U.S. Food and Drug Administration (FDA). The phase is based on the study's objective, the number of participants, and other characteristics. There are five phases: Early Phase 1 (formerly listed as Phase 0), Phase 1, Phase 2, Phase 3, and Phase 4. Not Applicable is used to describe trials without FDA-defined phases, including trials of devices or behavioral interventions.

Participation Criteria

Researchers look for people who fit a certain description, called eligibility criteria. Some examples of these criteria are a person's general health condition or prior treatments.

Eligibility Criteria

Eligibility Criteria

The key requirements that people who want to participate in a clinical study must meet or the characteristics they must have. Eligibility criteria consist of both inclusion criteria (which are required for a person to participate in the study) and exclusion criteria (which prevent a person from participating). Types of eligibility criteria include whether a study accepts healthy volunteers, has age or age group requirements, or is limited by sex.

Ages Eligible for Study

  • Adult
  • Older Adult

Accepts Healthy Volunteers

No

What is the study measuring?

Primary Outcome Measures

Primary Outcome Measures

In a clinical study's protocol, the planned outcome measure that is the most important for evaluating the effect of an intervention/treatment. Most clinical studies have one primary outcome measure, but some have more than one.
Outcome Measure

Time Frame: approximately 4 months after the last subject participating in
The time from the date for first documented response of complete response (CR) or partial response (PR) to the date of first documented of disease progression or death, whichever occurs first.
approximately 4 months after the last subject participating in

Secondary Outcome Measures

Secondary Outcome Measures

In a clinical study's protocol, a planned outcome measure that is not as important as the primary outcome measure for evaluating the effect of an intervention but is still of interest. Most clinical studies have more than one secondary outcome measure.
Outcome Measure
Measure Description

OS
Time Frame: approximately 12 months after the last subject participating in
The time from the starting date of study drug to the date of death due to any cause.
