X-396 (Ensartinib) Capsules in ALK-Positive NSCLC Patients With Brain Metastases

Study Overview
=================
Brief Summary
-----------------
To assess efficacy and safety of oral X-396 (Ensartinib) capsule in Chinese ALK-positive NSCLC patients with brain metastases, eligible patients will be enrolled with objective responses being primary outcome measures.

Detailed Description
-----------------
In this phase Ⅱ, open-label, single arm, multicenter study, efficacy and safety of oral X-396 capsule (Ensartinib) in 37 Chinese ALK-positive NSCLC patients with brain metastases will be assessed. Eligible patients will receive 225mg X-396 capsules once daily and objective responses of brain metastasis based on investigator assessment according to Response Assessment in Neuro-Oncology (RANO) are primary outcome measures.

What is the study measuring?
-----------------
Primary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |
| Intracranial objective response rate (iORR) based on investigator assessment according to RNAO-BM. | iORR per RANO-BM calculated as the proportion of patients with a best intracranial overall response defined as complete response (CR) or partial response (PR), based on investigator assessment. | 12 weeks | 

Secondary Outcome Measures

| Outcome Measure | Measure Description | Time Frame |
| --- | --- | --- |

| Progression-free survival based on intracranial response (iPFS) according to RANO-BM | Defined as time from first dose of X-396 capsule to intracranial disease progression or death due to any causes, assessed by investigator. | 36 months | 
| Time to progression based on intracranial response (iTTP) according to RANO-BM. | Defined as time from first dose of X-396 capsule to intracranial disease progression, assessed by investigator. | 36 months | 
| Duration of response based on intracranial response (iDOR) according to RANO-BM. | Defined as time from documentation of intracranial response (CR or PR) to intracranial disease progression or death, assessed by investigator. | 36 months | 
| Intracranial objective response rate (iORR) based on intracranial response according to RECIST 1.1. | iORR per RECIST 1.1 calculated as the proportion of patients with a best intracranial overall response defined as complete response (CR) or partial response (PR), based on investigator assessment. | 12 weeks | 
| Disease control rate based on intracranial response (iDCR) according to RECIST 1.1 | Defined as the percentage of patients who have achieved intracranial overall response of CR, PR and stable disease (SD), assessed by investigator. | 12 weeks | 
| Progression-free survival based on intracranial response (iPFS) according to RECIST 1.1 | Defined as time from first dose of X-396 capsule to intracranial disease progression or death due to any causes, assessed by investigator. | 36 months |
