Summary

This is a single-arm, multicenter Phase II clinical study designed to observe and evaluate the efficacy and safety of Iparomlimab and tuvonralimab plus chemotherapy in initially unresectable Stage III NSCLC. The study plans to enroll 69 Stage III NSCLC patients judged unresectable by a MDT team, with the R0 resection rate as the primary endpoint. After completing 2-4 cycles of conversion therapy, the MDT team reassesses resectability. Subjects deemed suitable for surgical resection undergo surgery within 6 weeks after the last dose of conversion therapy. Subjects deemed unsuitable for surgery receive radical chemoradiotherapy, starting within 6 weeks after the last conversion therapy dose. Subjects unsuitable for both surgery and chemoradiotherapy will have their subsequent treatment decided by the project team. Adjuvant therapy consists of Iparomlimab and tuvonralimab monotherapy (Q3W) for up to 16 cycles.

Conditions

Interventions

Type	Name	Description
DRUG	Iparomlimab and tuvonralimab plus chemotherapy	Squamous Cell Carcinoma: 2-4 cycles of Iparomlimab and tuvonralimab 5mg/kg Q3W (Day 1) + Albumin-bound Paclitaxel (100mg/m² Q3W D1/D8/D15 or130mg/m²D1/D8 or 260mg/m²D1) + Carboplatin (AUC=5) Q3W (D1) Non-Squamous Cell Carcinoma: 2-4 cycles of Iparomlimab and tuvonralimab 5mg/kg Q3W (D1) + Pemetrexed 500mg/m² Q3W (D1) + Carboplatin (AUC=5) Q3W (D1) Radical Chemoradiotherapy for Patients Unable to Undergo Surgery:Patients still unresectable after conversion therapy should start radical chemoradiotherapy within 6 weeks after the last conversion therapy dose. Chemoradiotherapy follows standard clinical practice, recommended as Cisplatin 30mg/m² QW (D1) + 60Gy radiotherapy. Adjuvant Therapy Phase:Iparomlimab and tuvonralimab 5mg/kg Q3W (D1) for up to 16 cycles.
