About this study
Official title: Neoadjuvant Tislelizumab Combined With Nab-Paclitaxel Followed by Distal Ureterectomy for Ureteral Cancer: An Open-Label, Single-Center, Single-Arm, Phase II Clinical Trial (TRUCE-U01)
This study is designed as an open-label, single-arm, single-center, phase II clinical trial, aiming to evaluate the efficacy and safety of neoadjuvant Tislelizumab combined with Nab-Paclitaxel followed by distal ureterectomy for patients with non-metastatic ureteral cancer (UTC). Patients enrolled will receive 2-3 cycles of Tislelizumab in combination with Nab-Paclitaxel every 3 weeks and then undergo distal ureterectomy (DU). The assessment of efficacy is based on the histology of specimen from DU, and treatment-related adverse events (TRAEs) will be recorded and evaluated according to CTCAE 5.0.

Receives: Drug: PD-1 inhibitior; Drug: Nab-paclitaxel; Procedure: distal ureterectomy |
What is being measured
The primary outcome is the main question the study is designed to answer.
Pathological Complete Response (pCR)
Defined as no residual tumor in the specimen from distal ureterectomy.
Measured: At the time of distal ureterectomy completed (within 14 weeks of the treatment initiated)
Secondary outcomes (8)
Treatment-related adverse events (TRAEs)
Treatment-related adverse events (TRAEs) ,defined as adverse events occurring from the start of treatment (C1D1) to 90 days after the completion of the last dose, including type, incidence rate, and severity grading (assessed according to the NCI-CTCAE V5.0 criteria)
Measured: From neoadjuvant treatment initiation to 90 days after the last cycle of treatment.
Pathological Downstaging (pDS)
Defined as a reduction in the pathological T stage and N stage of the distal ureterectomy specimen compared to the clinical T stage and N stage assessed at baseline
Measured: At the time of distal ureterectomy completed (within 14 weeks of the treatment initiated)
Objective Response (OR)
Defined as the achievement of partial response (PR) or complete response (CR) based on RECIST 1.1 criteria, as assessed by imaging studies after neoadjuvant therapy.
Measured: After completion of neoadjuvant therapy and before distal ureterotomy.
Events-Free Survival (EFS)
Defined as the time from treatment initiated to the first occurrence of delayed surgical disease progression, local tumor recurrence (including recurrence in the upper urinary tract and bladder, excluding non-muscle-invasive bladder cancer that can be resected by TURBT), distant metastasis, or death from any cause. The study will record the 1-, 2-, and 5-year EFS rates for the target population. Kaplan-Meier methods will be used to estimate the median EFS and 95% confidence interval limits, and Kaplan-Meier curves will be constructed to provide descriptive information on EFS.
Measured: up to 5 years
Overall Survival (OS)
Defined as the time from treatment initiated to death from any cause. The study will record the 1-, 2-, and 5-year OS rates for the target population. Kaplan-Meier methods will be used to estimate the median OS and 95% confidence interval limits, and Kaplan-Meier curves will be constructed to provide descriptive information on survival
Measured: up to 5 years
Recurrence-Free Survival (RFS)
Defined as the time from treatment initiated to the first occurrence of tumor recurrence (including recurrence in the upper urinary tract and bladder, excluding non-muscle-invasive bladder cancer that can be removed by TURBT). The study will record the 1-, 2-, and 5-year RFS rates for the target population. Kaplan-Meier methods will be used to estimate the median RFS and 95% confidence interval limits, and Kaplan-Meier curves will be constructed to provide descriptive information on RFS.
Measured: up to 5 years
Cancer-Specific Survival (CSS)
Defined as the time from enrollment to death caused by the tumor. The study will record the 1-, 2-, and 5-year CSS rates for the target population. Kaplan-Meier methods will be used to estimate the median CSS and 95% confidence interval limits, and Kaplan-Meier curves will be constructed to provide descriptive information on CSS.
Measured: up to 5 years
Nephron-Sparing Survival (NSS)
Defined as the time from treatment initiated to the absence of surgical indications for nephrectomy due to upper urinary tract tumor progression or recurrence, as well as the absence of distant metastasis caused by the primary upper urinary tract tumor and death from any cause. The study will record the 1-, 2-, and 5-year NSS rates for the target population. Kaplan-Meier methods will be used to estimate the median NSS and 95% confidence interval limits, and Kaplan-Meier curves will be constructed to provide descriptive information on NSS.
Measured: up to 5 years

Questions about this trial
What is this clinical trial studying?
A Phase 2 study testing PD-1 inhibitior, Nab-paclitaxel and distal ureterectomy in people with Ureteral Cancer and Neoadjuvant Therapy, run by Tianjin Medical University Second 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 8 inclusion and 17 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: looking for participants now, as of the sponsor's last update on 15 Aug 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 Hailong Hu, PhD (+86 13662096232, Huhailong@tmu.edu.cn), or a site near the patient. AzTrials does not enrol participants or take referrals.
What does the primary outcome measure?
Pathological Complete Response (pCR) (time frame: At the time of distal ureterectomy completed (within 14 weeks of the treatment initiated)). 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 15 Aug 2025.
