ClinConnect Summary

This clinical trial is studying a new treatment called SYS6010, comparing it to standard chemotherapy for patients with a specific type of lung cancer known as non-small cell lung cancer (NSCLC) that has a mutation in the EGFR gene. The goal is to see which treatment works better and is safer for patients whose cancer has either spread or is not able to be removed by surgery. The study is currently not recruiting participants, but it aims to include adults aged 18 to 75 who have been diagnosed with advanced or metastatic NSCLC and have at least one measurable tumor.

To be eligible for this trial, participants must have a confirmed EGFR mutation and have previously tried certain targeted therapies without success. They should also have a good performance status, meaning they are generally well enough to participate, and expect to live for at least three more months. If someone joins the study, they can expect to receive either the new treatment or standard chemotherapy while being closely monitored by health professionals for their response and any side effects. It's important for potential participants to understand the requirements and to discuss any questions or concerns with their doctor before considering joining the trial.

Patients with supratentorial and/or cerebellar metastasis (i.e., without mesencephalon, pons, or medulla involvement) who have received local treatment, have achieved stability for at least 2 weeks prior to the first dose of the study intervention (imaging shows no new brain metastasis or enlargement of existing brain metastasis, and all neurologic symptoms have stabilized or returned to normal), and do not require corticosteroid therapy or are receiving prednisone at a daily dose of ≤10 mg or equivalent doses of other corticosteroids, can participate in the study;
• • 3. Patients with a history of other malignant tumors within 3 years prior to the first dose of the study intervention, except for the following conditions: cured skin basal cell carcinoma or squamous cell carcinoma, superficial bladder cancer, prostate carcinoma in situ, and cervical carcinoma in situ, etc.;
• • 4. Patients who are known to be allergic to any component of SYS6010 or to humanized monoclonal antibody products; allergic to carboplatin, cisplatin, or pemetrexed, or have contraindications for their use;
• • 5. AEs caused by prior anti-tumor treatment have not recovered to ≤ Grade 1 (excluding Grade 2 alopecia, peripheral neurotoxicity, and other toxicities judged by the investigator to have no safety risk) according to NCI-CTCAE v5.0;
• • 6. Previously received systemic anti-tumor therapy for locally advanced or metastatic non-squamous NSCLC other than EGFR TKI; patients who have previously received adjuvant/neoadjuvant chemotherapy and experienced disease progression more than 12 months after the end of treatment are allowed to be included;
