Measured: From the first dose of study treatment (Day 1) up to Day 28 of Cycle 1 (cycle duration: 4 weeks)
Part 1: Recommended Phase 2 Dose (RP2D) of Fruquintinib in Combination With Tislelizumab
The RP2D of fruquintinib in combination with tislelizumab based on the safety and tolerability assessments in Part 1 patients.
Measured: From the first dose of study treatment (Day 1) up to Day 28 of Cycle 1 (cycle duration: 4 weeks)
Part 2: Objective Response Rate (ORR)
The ORR was defined as the percentage of patients with a confirmed best overall response (BOR) of complete response (CR) or partial response (PR) as determined by the investigator using RECIST v1.1. The BOR was defined as the best response recorded from the start of study treatment until documented RECIST v1.1 progression or the start date of new anticancer therapy, whichever came first. The CR was defined as disappearance of all target lesions. Any pathological lymph nodes (whether target or non-target) had a reduction in short axis to <10 millimeters (mm). The PR was defined as at least a 30% decrease in the sum of diameters of target lesions, taking as reference the baseline sum of diameters.
Measured: Tumor assessments performed every 8 weeks (+/-1 week) until PD, up to a maximum of approximately 34 months

Questions about this trial
What is this clinical trial studying?
A Phase 1/2 study testing Fruquintinib and Tislelizumab in people with Triple Negative Breast Cancer and Endometrial Cancer, run by Hutchmed at 16 sites in United States.
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 6 inclusion and 7 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: stopped early, as of the sponsor's last update on 14 Jul 2025. Status can change between updates, so confirm with the study contact before making plans.
Where is the study taking place?
The record lists 16 sites in United States. 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 combined phase mean?
Phase 1 studies test a treatment in a small group of people for the first time or in a new way, mainly to check safety and find the right dose.
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?
Yes. Results are posted in the registry (first posted 14 Jul 2025). A summary is in the For doctors view, and the full results are on ClinicalTrials.gov.
How can a doctor refer a patient or contact the research team?
The record lists no contact. The official record names the sponsor, who can be asked directly. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Part 1: Number of Patients With Dose-Limiting Toxicities (DLTs) (time frame: From the first dose of study treatment (Day 1) up to Day 28 of Cycle 1 (cycle duration: 4 weeks)). The study lists 3 primary outcomes in all. 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 14 Jul 2025.
