Carcinoma, Non-Small-Cell Lung
Conditions
Brief summary
This is a two-arm, randomized, multicenter phase II clinical study to evaluate the efficacy and safety of the Iparomlimab and Tuvonralimab combined with 2 or 4 cycles of chemotherapy as neoadjuvant therapy for resectable stage II-IIIB (N2 only) NSCLC.
Interventions
Iparomlimab and Tuvonralimab 5mg/kg:5mg/kg,q3W Platinum-based doublet chemotherapy:q3w

Eligibility
Inclusion criteria
* Histologically or cytologically confirmed, treatment-naïve Stage II-IIIB (N2 only) non-small cell lung cancer (NSCLC) according to the 9th edition of the American Joint Committee on Cancer (AJCC). Only patients judged as T4 based on tumor size are allowed to be enrolled; other T4 conditions (e.g., invasion of the diaphragm, mediastinal involvement) are not permitted. * MDT assessment (including a thoracic surgeon) confirms resectability. * Provision of tumor tissue for biomarker analysis (e.g., PD-L1 testing, gene sequencing). * At least one measurable lesion per RECIST v1.1. * ECOG performance status 0 or 1.
Exclusion criteria
* Confirmed EGFR or ALK mutations. * Other malignancies within 5 years (exceptions: adequately treated cervical carcinoma in situ, basal or squamous cell skin cancer, localized prostate cancer post-radical surgery, ductal carcinoma in situ post-radical surgery). * Prior treatment with immune checkpoint inhibitors (e.g., PD-1/PD-L1 inhibitors, CTLA-4 inhibitors) or immunostimulatory antibodies (e.g., anti-ICOS, CD40, CD137, GITR, OX40), or anti-tumor immune cell therapy. * Use of immunosuppressants or systemic corticosteroids (\>10 mg/day prednisone equivalent) within 2 weeks prior to enrollment.
Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Pathologic Complete Response (pCR) Rate | One week postoperatively | Pathologic complete response (pCR) rate is defined as the percentage of participants with absence of viable tumor cells in the resected lung tumor bed and lymph nodes. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Objective Response Rate (ORR) | Prior to surgery | Objective Response Rate (ORR) is defined as the percentage of participants with a best response of complete response (CR) or partial response (PR) on preoperative imaging among all subjects who received neoadjuvant therapy and had at least one post-baseline imaging assessment. |
| R0 Resection rate | At time of surgery | R0 Resection rate is defined as the percentage of participants who achieve complete surgical resection (R0). |
| Major Pathologic Response (MPR) Rate | One week postoperatively | Major pathologic response (MPR) rate is defined as percentage of participants with ≤10% viable tumor cells in the resected lung tumor bed and lymph nodes. |
| Disease-free survival (DFS) | up to 3 years | Disease-free survival (DFS) is the length of time from postoperative baseline imaging confirmation of no residual disease to disease recurrence or death from any cause, whichever occurs first. |
| Overall Survival (OS) | up to 3 years | Overall Survival (OS) is the length of time after initial administration the participant remains alive. |
| 2-Year Event-Free Survival (EFS) Rate | up to 2 years | EFS is defined as the time from the first study treatment to the occurrence of any event, including disease progression or deterioration preventing surgery, inability to achieve gross resection, disease recurrence, or death from any cause. The 2-year EFS rate was estimated using the Kaplan-Meier method. |
