Brief 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.

Iparomlimab and tuvonralimab plus chemotherapy
OTHERPatients will receive Iparomlimab and tuvonralimab (5 mg/kg) plus chemotherapy (nab-paclitaxel, pemetrexed, or docetaxel) every 3 weeks.
Interventions
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.
Eligibility Criteria
You may qualify if:
- Signed an informed consent form
- Patients aged ≥18
- Histologically or cytologically confirmed Stage III (AJCC 9th ed.) squamous or non-squamous NSCLC (mixed tumors classified by predominant cell type), deemed unresectable by the MDT team based on at least one of the following criteria:
- Ipsilateral multi-station or confluent mediastinal lymph node metastasis: Imaging shows ipsilateral multi-station lymph node metastasis or confluent lymph node mass (\>3cm diameter) or invasion of surrounding organs, making complete surgical clearance impossible.
- Contralateral or supraclavicular lymph node metastasis (N3): This includes contralateral hilar and mediastinal lymph node metastasis, or ipsilateral/contralateral supraclavicular lymph node metastasis.
- Invasion of vital organs or major vessels: Anatomical tumor or lymph node invasion directly involving the heart, major vessels (e.g., aorta, main pulmonary artery), trachea, esophagus, vertebral body (\>50% involvement), or brachial plexus.
- Extensive chest wall and pleural invasion: Involvement of ribs, intercostal muscles, and chest wall soft tissues is extensive, requiring large chest wall resection that the patient's pulmonary function cannot tolerate, or impossible to clear surgically.
- Special anatomical location: e.g., superior sulcus tumor (Pancoast tumor) invading vertebrae/nerve plexus, recurrent laryngeal nerve involvement causing vocal cord paralysis, tumor extent precluding R0 resection.
- Patient unable to tolerate lobectomy or pneumonectomy: Insufficient cardiopulmonary reserve, severe cardiovascular disease, coagulation dysfunction, or other systemic diseases precluding lobectomy or pneumonectomy.
- at least one measurable lesion according to RECIST 1.1 criteria
- ECOG PS 0-1.
- Pulmonary function must meet: FEV1 \> 1.0 L and FEV1%\> 40%
- appropriate organ function
You may not qualify if:
- NSCLC with small cell component identified on pathology (regardless of proportion); Histological types of large cell neuroendocrine carcinoma, sarcomatoid carcinoma, or NSCLC-NOS.
- Known EGFR mutation or ALK rearrangement positivity (eligibility of subjects with other driver gene positivity will be determined by the project biomarker expert group).
- Prior systemic anti-tumor therapy or thoracic radiotherapy.
