A Multicenter, Non-interventional, Observational Study of Taletrectinib for Advanced ROS1+ NSCLC With Brain Metastases
This is a multicenter, non-interventional, observational real-world study to evaluate the efficacy and safety of Taletrectinib in ROS1-positive non-small cell lung cancer (NSCLC) with brain metastases. Patients deemed eligible for Taletrectinib by their physicians were enrolled after providing informed consent. Taletrectinib will be administered according to clinical practice and data on treatment patterns, clinical outcomes, and safety will be collected during routine evaluations.
⁃ Patients must meet all of the following criteria to be eligible for enrollment into the study:
• Age ≥ 18 years.
• Histologically or cytologically metastatic NSCLC (UICC/AJCC TNM Staging System, 9th Edition, Stage Ⅳ).
• At least one measurable target tumor lesion as accessed by RECIST v1.1 criteria.
• Radiographically confirmed brain metastasis(es) , with stable CNS symptoms within 2 weeks prior to enrollment.
• Documented ROS1 gene fusion identified by an approved molecular testing method (FISH, RT-PCR, or NGS).
• Considered by the investigator to be candidates for Taletrectinib treatment ; OR Patients with ≤6 months of prior Taletrectinib exposure enrolled retrospectively. (Note: For retrospective patients deceased before enrollment, waiver of informed consent is required. Patients who initiated and discontinued treatment within 6 months prior to signing informed consent are eligible).
• Signed Informed Consent.
