Ipilimumab N01 Plus Sintilimab and Lenvatinib as First-line Therapy for Locally Advanced or Metastatic TFE3-Rearranged Renal Cell Carcinoma: A Prospective, Multicenter, Single-Arm, Phase II Clinical Trial

Summary

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.
