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 group | Role | What they receive |
|---|---|---|
| High risk recurrent renal cell carcinoma patients receiving treatment with Toripalimab | High 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). Receives: Drug: Toripalimab |
What is being measured
The primary outcome is the main question the study is designed to answer.
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)
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.
