About this study

Official title: Nephron-sparing Treatment Combining Tislelizumab and Nab-Paclitaxel for Renal Pelvic Cancer: An Open-Label, Single-Center, Single-Arm, Phase II Clinical Trial (TRUCE-U03)

This study is designed as an open-label, single-arm, single-center, phase II clinical trial, aiming to evaluate the efficacy of nephron-sparing treatment combining Tislelizumab and Nab-Paclitaxel for HER-2 expressing renal pelvic cancer (RPC) . Patients enrolled will receive 2-3 cycles of Tislelizumab in combination with Nab-Paclitaxel every 3 weeks and then undergo evaluation. Patients who achieve all of the following criteria of "well response and tolerance" will receive further maintenance treatment:

(1)The patient achieves a complete response (CR) or partial response (PR) according to the RECIST 1.1 criteria, indicating that the tumor is well-controlled. (2) If the patient has residual lesions, it should be confirmed by the clinical physician that these lesions can be eliminated through laser ablation via ureteroscopy. (3)The patient has not experienced any treatment-related adverse events (TRAEs) that warrant discontinuation of therapy during systemic treatment. (4)The patient is willing to undergo further maintenance therapy. If the patient meets all the criteria above, ureteroscopic biopsy should be performed. If residual lesions are detected under the ureteroscope, endoscopic intervention (e.g., laser ablation, cryoablation) should be carried out simultaneously to eliminate these residual lesions. Patients who meet the above criteria will proceed with no less than 2 cycles of maintenance systemic therapy (Tislelizumab + Nab-Paclitaxel). Patients who do not meet the criteria will be excluded from the study and are recommended to undergo salvage radical nephroureterectomy (RNU) as soon as possible. One-year Nephron-Sparing Survival (1 year-NSS): Defined as the absence of surgical indications for nephrectomy due to progression or recurrence of upper urinary tract urothelial carcinoma, distant metastasis caused by the primary upper urinary tract tumor, or death from any cause within 1 year from the initiation of treatment. Treatment-related adverse events (TRAEs) will be recorded and evaluated according to CTCAE 5.0.

Nab-paclitaxel, Tislelizumab, endoscopic intervention

What participants receive

What participants receive. In a randomised study each person is assigned to one group by chance.

  • Nab-paclitaxelDrug

    Nab-Paclitaxel 125 mg/m2 IV will be administered on Day 1 every 3 weeks for 2-3 cycles before evaluation, then on Day 1 every 3 weeks for maintenance therapy after evaluation (only for patients who achieved the criteria of "well response and tolerance").

  • TislelizumabDrug

    Tislelizumab 200mg iv will be administered on Day 1 every 3 weeks for 2-3 cycles before evaluation, then on Day 1 every 3 weeks for 3-6 cycles as maintenance therapy after evaluation (only for patients achieved the criteria of "well response and tolerance").

  • endoscopic interventionProcedure or surgery

What is being measured

The primary outcome is the main question the study is designed to answer.

  1. One-year Nephron-Sparing Survival (1-year-NSS)

    This is defined as the absence of surgical indications for nephrectomy due to progression or recurrence of upper urinary tract urothelial carcinoma, distant metastasis caused by the primary upper urinary tract tumor, or death from any cause within 1 year from the initiation of treatment. Kaplan-Meier curves will be constructed to provide descriptive information on nephron-sparing survival.

    Measured: up to 1 year from the initiation of treatment.

Secondary outcomes (7)
  1. 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 treatment initiation to 90 days after the last cycle of treatment.

  2. Clinical Complete Response (cCR)

    Defined as the achievement of a complete response (CR) based on RECIST 1.1 criteria in radiological assessment following neoadjuvant therapy, negative results on urinary cytology, absence of residual tumor in the upper urinary tract as demonstrated by ureteroscopy, and no residual tumor in the specimen from ureteroscopic biopsy.

    Measured: At the time of ureteroscopic biopsy (for efficacy evaluation) completed (within 14 weeks of the treatment initiated)

  3. 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 at efficacy evaluation.

    Measured: After completion of the last cycle (cycle 2 or cycle 3,each cycle is 21 days) of therapy.

  4. 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

  5. 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

  6. 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

  7. 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

Who may be eligible to take part?

The sponsor lists 9 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 18 Nov 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?
