About this study
Official title: An Exploratory Study of Iparomlimab and Tuvonralimab (QL1706) in Combination With Bevacizumab for the Treatment of Unresectable or Metastatic MSI-H/dMMR Colorectal Cancer
This is a single-arm, multi-center, exploratory study evaluating the efficacy and safety of iparomlimab and tuvonralimab (QL1706) in combination with bevacizumab for the treatment of patients with microsatellite instability-high (MSI-H) or mismatch repair-deficient (dMMR) unresectable or metastatic colorectal cancer. Eligible participants who meet the inclusion and exclusion criteria will provide written informed consent and receive QL1706 at 5.0 mg/kg and bevacizumab at 7.5 mg/kg on Day 1 of every 3-week cycle (Q3W), until disease progression or completion of 2 years of treatment. The primary endpoint of this study is objective response rate (ORR). Secondary endpoints include disease control rate (DCR), duration of response (DoR), progression-free survival (PFS), overall survival (OS), PFS and OS rates at 6, 12, and 24 months, and safety.

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing QL1706 and Bevacizumab in people with Unresectable Colorectal Cancer and Metastatic Colorectal Cancer (CRC), run by Qianfoshan Hospital at 1 site in China.
The full registered description is in the About this study section and the official record.
Who may be eligible to take part?
The sponsor lists 12 inclusion and 25 exclusion criteria. Eligibility is decided by the study team after screening, so read the full criteria and contact a listed site.
Is this clinical trial currently recruiting?
The record says: opening soon, as of the sponsor's last update on 6 Jun 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 1 site in China. Whether a site is taking part right now should be confirmed with that site. See every site.
What are the possible benefits and risks?
They depend on the study and the treatment, and no study can promise a benefit. The study team explains the known risks during informed consent, before anyone joins; the record itself does not list them.
What does this phase mean?
Phase 2 studies give the treatment to a larger group to see whether it has the intended effect and to keep checking safety.
Not every study follows the same path, and some studies (observational studies, device studies) have no phase.
Are results available for this study?
This study is still under way. Results are not available in the source record yet.
How can a doctor refer a patient or contact the research team?
Contact Jun Wang, Associate Director, Department of Oncology, MD, PHD (0531-82169851, ggjun2005@126.com), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
ORR (time frame: approximately 6 months after the last subject participating in). It is what the study was designed to measure, not a finding.
Where can I read the original study information?
Does a listing mean the treatment is approved or proven to work?
No. A listing means the study is registered. It does not show that the treatment is safe, works, or is approved by a regulator.
How often is this information updated?
AzTrials copies changed records from ClinicalTrials.gov every night and reloads the whole registry every week. The sponsor last updated this record on 6 Jun 2025.
