Study on MRD Prediction of Efficacy of Toripalimab in the Treatment of High-risk Recurrent Renal Carcinoma
Sponsor: Tianjin Medical University Second Hospital
Summary
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.

Toripalimab
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.
