Leírás
Co-hort 1: Strict co-hort Inclusion criteria1：Histologically or cytologically confirmed stage IIIB-IV non-small cell lung cancer; Inclusion criteria2：Age ≥ 18 years at the time of signing the informed consent form; Inclusion criteria3：ALK-positive status confirmed by tissue samples or blood tests at each centre; Inclusion criteria4：History of resistance to lorlatinib treatment; prior use of ensartinib is not permitted; patients must have received a maximum of two other ALK-TKIs; prior receipt of ≤2 courses of chemotherapy is permitted; ECOG Performance Status (PS) score between 0 and 2, with no deterioration within 2 weeks prior to study entry;
Co-hort 2 (Compassionate Use Cohort):
Inclusion criteria1： Resistance to lorlatinib treatment; Inclusion criteria2： No restrictions on prior use of ensartinib or the number of prior lines of other ALK-TKIs and chemotherapy; Inclusion criteria3：Subjects with concomitant leptomeningeal metastases may be enrolled. For patients with leptomeningeal metastases (LM), diagnosis must be based on the three criteria outlined in the EANO-ESMO guidelines: clinical presentation, cranial imaging, and cerebrospinal fluid cytology. Tissue samples must not be derived from tumour sites that have previously undergone radiotherapy; however, new lesions arising after local treatment may be included; Inclusion criteria4：ECOG performance status of 0-4; Inclusion criteria5： Adequate organ system function, as determined by the investigator; Inclusion criteria6：All other inclusion criteria are consistent with items 1, 2 and 3 of Cohort 1.
Exclusion criteria1：Concurrent malignant tumours. Exclusion criteria2：Patients with leptomeningeal metastases (LM) who are unable to undergo contrast-enhanced MRI.
Exclusion criteria3：Patients who have undergone surgery within 4 weeks prior to treatment with the study drug, except for minor procedures deemed by the investigator not to preclude participation in the trial; or patients scheduled to undergo major surgery during the study period.
Exclusion criteria4：Patients who have experienced a marked deterioration in symptoms or signs within 2 weeks prior to screening and are deemed by the investigator to be unsuitable for participation in the trial.

Egyéb: Strict Queue
Patients with a performance status (ECOG) score of 0-2 and brain parenchymal metastases were enrolled in Cohort 1.
|
Ensatinib is administered at a dose of 225 mg once daily, either on an empty stomach or with food; anlotinib is administered at a dose of 10 mg once daily, in 21-day cycles; treatment continues until disease progression, the occurrence of intolerable toxicity, withdrawal at the discretion of the investigator or the subject, loss to follow-up, initiation of other anticancer therapy, or death.

Időkeret |
|---|---|---|

Objective response rate (ORR)
Időkeret: After the patients were enrolled according to the inclusion criteria, the tumor assessment will be conducted every 6 weeks, and the maximum duration of the assessment is 6 months until the patients have disease progression or cannot tolerate the treatmen
|
If the patient has available imaging results from within 28 days prior to the first dose (bone scans may be accepted if performed within 2 months prior to the first dose), repeat imaging is not required.
Tumour assessment should be performed every 6 weeks (±4 days) until tumour progression.
|
After the patients were enrolled according to the inclusion criteria, the tumor assessment will be conducted every 6 weeks, and the maximum duration of the assessment is 6 months until the patients have disease progression or cannot tolerate the treatmen

Secondary endpoints include progression-free survival (PFS)
Időkeret: The assessment was conducted every 2 cycles (6 weeks and 24 days), and the maximum duration of the assessment was 6 months until the patient's condition progressed or could not tolerate the treatment. As of June 2028, the follow-up work has been complete
|
Progression-free survival (PFS): defined as the time from randomisation to the first occurrence of objective tumour progression or death, whichever comes first.
|
The assessment was conducted every 2 cycles (6 weeks and 24 days), and the maximum duration of the assessment was 6 months until the patient's condition progressed or could not tolerate the treatment. As of June 2028, the follow-up work has been complete
|
|
Overall survival (OS)
Időkeret: The assessment was conducted every 2 cycles (6 weeks and 24 days), and the maximum duration of the assessment was 6 months until the patient's condition progressed or could not tolerate the treatment. As of June 2028, the follow-up work has been complete
|
Overall survival (OS): defined as the time from randomisation to the patient's death from any cause.
|
The assessment was conducted every 2 cycles (6 weeks and 24 days), and the maximum duration of the assessment was 6 months until the patient's condition progressed or could not tolerate the treatment. As of June 2028, the follow-up work has been complete
|
|
Duration of Response (DOR)
Időkeret: The assessment was conducted every 2 cycles (6 weeks and 24 days), and the maximum duration of the assessment was 6 months until the patient's condition progressed or could not tolerate the treatment. As of June 2028, the follow-up work has been complete
|
Duration of Response (DOR): Defined as the time from the first assessment of complete response (CR) or partial response (PR) until the first assessment of disease progression (PD) or death from any cause.
|
The assessment was conducted every 2 cycles (6 weeks and 24 days), and the maximum duration of the assessment was 6 months until the patient's condition progressed or could not tolerate the treatment. As of June 2028, the follow-up work has been complete

|
Disease Control Rate (DCR)
Időkeret: The assessment was conducted every 2 cycles (6 weeks and 24 days), and the maximum duration of the assessment was 6 months until the patient's condition progressed or could not tolerate the treatment. As of June 2028, the follow-up work has been complete
|
Disease Control Rate (DCR): Defined as the proportion of patients who achieve complete response (CR), partial response (PR) or stable disease (SD) following treatment and maintain this status for a certain period.
