About this study

This phase II, multicenter, single-arm, open-label study evaluates first-line ipilimumab N01 plus sintilimab and lenvatinib in patients with locally advanced or metastatic TFE3-rearranged renal cell carcinoma (TFE3-rRCC), a rare subtype lacking established first-line systemic therapy. Eligible patients (age ≥14 years, ECOG ≤2, measurable disease per RECIST v1.1, no prior systemic therapy) will receive ipilimumab N01 1 mg/kg Q6W for 4 cycles, sintilimab 200 mg Q3W for up to 35 cycles, and lenvatinib 12 mg or 8 mg QD continuously. The primary endpoint is objective response rate (ORR) per RECIST v1.1. Secondary endpoints include disease control rate, duration of response, progression-free survival, overall survival, safety per NCI CTCAE v5.0, and quality of life. Exploratory biomarker analyses will assess potential predictors of treatment response.

Read the detailed description

This prospective, multicenter, single-arm, open-label, phase II clinical trial evaluates the efficacy and safety of first-line ipilimumab N01 plus sintilimab and lenvatinib in patients with locally advanced or metastatic TFE3-rearranged renal cell carcinoma (TFE3-rRCC). TFE3-rRCC is a rare, aggressive renal cell carcinoma subtype with no established standard first-line systemic therapy. Preliminary retrospective data suggest that immune checkpoint inhibitor-based combination therapy may improve clinical outcomes in this population.

Eligible patients (age ≥14 years; ECOG performance status ≤2) must have histologically confirmed, locally advanced or metastatic TFE3-rRCC diagnosed by fluorescence in situ hybridization (FISH) and/or next-generation sequencing, with measurable disease per RECIST v1.1, and no prior systemic therapy (or prior targeted therapy ≤1 month with adequate washout). A total of 66 participants will be enrolled using a Simon two-stage optimal design (21 patients in stage 1; 39 in stage 2).

Participants will receive ipilimumab N01 1 mg/kg intravenously every 6 weeks for the first 4 cycles (induction); sintilimab 200 mg intravenously every 3 weeks for up to 35 cycles (approximately 2 years); and lenvatinib 12 mg (body weight ≥60 kg) or 8 mg (body weight <60 kg) orally once daily continuously until disease progression, unacceptable toxicity, or loss of clinical benefit.

The primary endpoint is objective response rate (ORR) assessed by investigators according to RECIST v1.1. Secondary endpoints include disease control rate (DCR), duration of response (DOR), progression-free survival (PFS), overall survival (OS), cancer-specific survival (CSS), ORR and DCR per imRECIST, safety profile according to NCI CTCAE v5.0, and quality of life measured by EORTC QLQ-C30, FKSI-DRS, EuroQOL, and VAS. Exploratory analyses will evaluate biomarkers (tumor tissue PD-1, PD-L1, CD4, CD8, tumor-infiltrating lymphocytes, tumor mutational burden; peripheral blood cytokines, circulating tumor DNA, immune cell subsets by single-cell sequencing) and functional MRI sequences as potential predictors of treatment response.

What participants receive

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

  • Ipilimumab InjectionDrug

    Also called Ipilimumab

    A human monoclonal antibody targeting CTLA-4.

  • Sintilimab injectionDrug

    Also called Sintilimab

    Recombinant human-derived immunoglobulin G (IgG4)-type anti-programmed cell death receptor-1 (PD-1) monoclonal antibody, by binding to PD-1 and blocking PD-1 binding to PD-L1 and PD-L2, disarms the immunosuppressive effect, activates T-cell function, and enhances T-cell immunosurveillance and killing ability against tumors to generate tumor immune response.

  • LenvatinibDrug

    A multi-target tyrosine kinase inhibitor (VEGFR1-3, FGFR1-4, PDGFRα, KIT, RET).

What is being measured

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

    Disease control rate is the proportion of participates with complete response (CR), partial response (PR) or stable disease (SD), based on RECIST1.1.

    Measured: 3 years

    Duration of response is the time from first response (complete or partial response) to disease progression or death.

    Measured: 3 years

  6. Cancer-Specific Survival (CSS)

    The period from the time the patient was diagnosed with the tumor or began treatment until death directly caused by the tumor

    Measured: 3 years

  7. Quality of Life, European Organization for Research and Treatment of Cancer Quality-of-Life Questionnaire-Core 30(EORTC QLQ-C30)

    Used to assess the multi-dimensional impact of cancer treatment on the quality of life of patients

    Measured: 3 years

  8. Functional Assessment of Cancer Therapy Kidney Syndrome Index-Disease-Related Symptoms (FKSI-DRS)

    Used to assess the impact of specific symptoms related to kidney cancer on quality of life

    Measured: 3 years

  9. European Quality of Life (EuroQOL)

    Used to assess the current overall health status of the patient

    Measured: 3 years

  10. Visual Analogue Scale(VAS)

    Used to assess the pain condition and severity of the patients

    Measured: 3 years

Questions about this trial

What is this clinical trial studying?

A Phase 2 study testing Ipilimumab Injection, Sintilimab injection and Lenvatinib in people with Renal Cell Carcinoma (Kidney Cancer) and Immunotherapy, run by West China 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 10 inclusion and 13 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 20 Jul 2026. 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 Hao Zeng, Doctor (+86-18980602129, kucaizeng@163.com), or a site near the patient. AzTrials does not enrol participants or take referrals.

What does the primary outcome measure?

Objective Response Rate (ORR) (time frame: 3 years). 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 20 Jul 2026.
