  7. Vital organ function meets the following requirements (excluding use of any blood components and cell growth factors within 14 days) : normal bone marrow reserve function; Absolute neutrophil count (ANC)≥1500/µL, Platelets≥100 000/µL, Hemoglobin ≥5.6 mmol/L (9g/dL); Normal renal function or serum creatinine ≤1.5 mg/d and/or creatinine clearance ≥30 mL/min for participants with creatinine levels \>1.5×institutional ULN; Normal liver function or Total bilirubin ≤1.5xULN, or direct bilirubin≤ULN for participants with total bilirubin levels \>1.5×ULN; AST (SGOT) and ALT (SGPT) ≤2.5×ULN; International normalized ratio (INR) or prothrombin time (PT) ≤1.5×ULN.

About this study

Official title: Predictive Value of Minimal Residual Disease for Efficacy of Toripalimab in High-risk Recurrent Renal Cell Carcinoma Following Nephrectomy: A Prospective Single-arm Study

This is a prospective cohort study aimed at clarifying the predictive value of MRD for postoperative DFS and OS in high-risk recurrent renal cell carcinoma patients who have undergone radical nephrectomy and received adjuvant treatment with Toripalimab. Further differentiating patients who need adjuvant immunotherapy.

Read the detailed description

The study population is high-risk recurrent renal cell carcinoma patients who have undergone radical nephrectomy and meet the criteria of ECOG Score 0-1, no residual tumor on imaging. The study subjects will undergo MRD testing about 3 weeks after surgery, and the drug will be started within 4 weeks of surgery. Imaging (CT, MRI) will be performed from the first dose of Toripalimab, every 12 weeks, and DFS will be evaluated. Survival will be recorded every 3 months. The study aims to investigate the predictive value of MRD technology for DFS and OS in these patients after surgery and provide reference for distinguishing patients who need adjuvant immunotherapy.

What participants receive

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

  • ToripalimabDrug

    Toripalimab is a newly developed recombinant humanized (with a degree of 97%) anti-PD-1 monoclonal antibody (Chinese patent authorization number CN104250302B, PCT patent publication number (WO2014/206107A1)), belonging to the human IgG4/Kappa subtype. A point mutation of proline (S228P) has been introduced at the serine protein site 228 in the IgG4 hinge region to increase antibody stability and reduce possible IgG4 Fab chain substitutions. It can specifically bind to PD-1 and effectively block the interaction between PD-1 and its ligands PD-L1 (i.e. B7-H1) and PD-L2 (i.e. B7-DC), thereby activating cytotoxic T lymphocytes, increasing lymphocyte proliferation, and cytokine secretion, especially IFN - γ. To achieve the goal of using the immune system to kill tumors.

Study groupRoleWhat they receive
High risk recurrent renal cell carcinoma patients receiving treatment with ToripalimabHigh risk recurrence renal cell carcinoma patients who have undergone radical surgery will begin receiving treatment with Toripalimab within 4 weeks after surgery.Toripalimab is administered intravenously once every 3 weeks for a maximum of 17 cycles (approximately 1 year) or until disease recurrence, unacceptable toxic effects, intercurrent illness preventing further administration of Toripalimab, decision by the investigator, a new cancer resulting in active treatment, pregnancy, or nonadherence to the protocol. Imaging (CT, MRI) tests will be performed 12 weeks after the initial dosing and every 12 weeks for 2 years.Definition of High risk of recurrence :tumor stage 2 with nuclear grade 4 or sarcomatoid differentiation, tumor stage 3 or higher, regional lymph-node metastasis, regional lymph-node metastasis, or stage M1 with NED (M1 with no evidence of disease) (M1 NED, defined as resection of the primary tumor and solid, isolated, soft-tissue metastases).

What is being measured

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

  1. Effect on the disease-free survival in the trial patients.

    The sample size was calculated based on the objective response rate reported in the previous literature, and the target assumption was that the recurrence rate was 30% at 2 years and that adjuvant therapy with Toripalimab would prevent 50% of relapses.

    Measured: Imaging (CT, MRI) was evaluated at 12 weeks after the first dose of Toripalimab and every 12 weeks. Until the tumor recurred or could not tolerate the side effects or the drug for 1 year.

Secondary outcomes (1)
  1. Effect on the overall survival in the trial patients.

    The sample size was calculated based on the objective response rate reported in the previous literature, and the target assumption was that the recurrence rate was 30% at 2 years and that adjuvant therapy with Toripalimab would prevent 50% of relapses.

    Measured: Imaging (CT, MRI) was evaluated 12 weeks after initial dosing and every 12 weeks until the tumor recurred or could not tolerate side effects or drugs for 1 year, and survival was recorded every 3 months.

Who may be eligible to take part?

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 Jun 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.

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?

What does the primary outcome measure?

Effect on the disease-free survival in the trial patients. (time frame: Imaging (CT, MRI) was evaluated at 12 weeks after the first dose of Toripalimab and every 12 weeks. Until the tumor recurred or could not tolerate the side effects or the drug for 1 year.). 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.
