结局指标
主要结局
Patient Benefit Rate at 12 Weeks
时间窗: 12 weeks from randomisation
Percentage of patients with patient benefit at week 12. Patient benefit was defined by the absence of central nervous system (CNS) disease progression according to Response Evaluation Criteria in Solid Tumours (RECIST) version 1.1 in addition to no tumour-related worsening of the neurological signs and symptoms (NSS), no tumour-related increase in corticosteroid dosage and no progression of extra CNS disease according to RECIST 1.1
次要结局
- Progression-Free Survival(From first drug administration until 28 days after end of treatment, up to 805 days)
- Overall Survival(From first drug administration until 28 days after end of treatment, up to 805 days)
