• Conditions: Non-squamous Non-small Cell Lung Cancer

Brief Summary

This study targets patients with advanced NSCLC driven with positive driver genes who have failed TKI treatment, enrolling 36-42 participants. Patients will receive JS207 (10 or 15 mg/kg, IV, d1) + pemetrexed (500 mg/m², IV, d1) + platinum-based chemotherapy (carboplatin AUC5 or cisplatin 75 mg/m², d1) every 3 weeks for 4 cycles. Afterward, JS207 and pemetrexed will continue as maintenance therapy until discontinuation criteria are met. The study aims to assess the safety, tolerability, and preliminary efficacy of JS207 combination therapy.

Detailed Description

This study enrolls patients with advanced non-small cell lung cancer (NSCLC) who have positive driver genes and have failed TKI treatment. Approximately 36-42 patients are expected to be enrolled and receive treatment with JS207 (10 mg/kg or 15 mg/kg, IV, d1) + pemetrexed (500 mg/m², IV, d1) + platinum-based chemotherapy (carboplatin: AUC5, d1 or cisplatin 75 mg/m², d1) every 3 weeks (Q3W) for a total of 4 cycles.After the 4 cycles, patients will continue receiving JS207 (10 mg/kg or 15 mg/kg, IV, d1) + pemetrexed (500 mg/m², IV, d1) every 3 weeks (Q3W) until they meet the criteria for treatment discontinuation.The study aims to evaluate the safety, tolerability, and preliminary efficacy of JS207 in combination with pemetrexed and platinum-based chemotherapy.

6. Being able to provide a qualified test report for positive driver gene, or agreeing to provide a qualified sample for driver gene testing.
7. According to the RECIST v1.1 criteria, the subject has at least 1 measurable lesion.
8. Performance status score of 0-1 according to the Eastern Cooperative Oncology Group (ECOG) scale.
9. Expected survival period ≥ 12 weeks.
10. The function of important organs meets the requirements of the protocol.
11. Female subjects of childbearing potential, and male subjects whose partners are females of childbearing age, need to adopt a highly effective contraceptive measure during the study treatment period and for at least 6 months after the last administration.
12. Voluntarily joining this study, signing the informed consent form, having good compliance, and cooperating with the follow-up.

Exclusion Criteria

1. Diseases accompanied by those listed in the protocol, including those with histopathological or cytopathological confirmation of the tumor combined with neuroendocrine tumor (including small cell lung cancer, large cell neuroendocrine carcinoma, etc.) components, or with the squamous cell carcinoma component exceeding 10%; known meningeal metastasis; symptomatic brain metastasis; the tumor encircling important blood vessels or with obvious necrosis and cavities, and the investigator deems that it may pose a risk of bleeding, etc.
2. Treatment received as listed in the protocol, including immunologically mediated treatment; drugs targeting the anti-VEGF pathway, etc.
3. Having an obvious bleeding tendency or a history of severe coagulation dysfunction.
4. Gastrointestinal perforation, intra-abdominal fistula or intra-abdominal abscess occurred within 6 months before the first administration, or currently having high-risk factors for perforation/fistula formation of the hollow viscus as judged by the investigator.
5. Having a serious, unhealed or ruptured wound, active ulcer or untreated fracture.
6. Having uncontrolled hypertension, or a history of hypertensive crisis or hypertensive encephalopathy.
7. Expected that the toxicity of previous anti-tumor treatment has not recovered to ≤ grade 1 according to the Common Terminology Criteria for Adverse Events (CTCAE).
8. Known allergy to the investigational drug or its excipients, pemetrexed, platinum drugs (carboplatin/cisplatin), or known history of ≥ grade 3 allergy to antibody drugs in the past.
