Abstract Purpose: The phase II prospective, noncomparative BRAIN study (NCT00800202) investigated efﬁcacy and safety of bevacizumab in chemotherapy-na€ve or pretreated patients with non– small cell lung cancer (NSCLC) and asymptomatic untreated brain metastases to provide data in this previously unexplored subgroup. Experimental Design: Patients with stage IV nonsquamous NSCLC, Eastern Cooperative Oncology Group performance status 0–1, and untreated, asymptomatic brain metastases received ﬁrst-line bevacizumab (15 mg/kg) plus carboplatin (area under the curve 6) and paclitaxel (200 mg/m2) every 3 weeks (B þ CP), or second-line bevacizumab plus erlotinib (150 mg/d; B þ E). Six-month progression-free survival (PFS) was the primary endpoint. The trial could be stopped if there were more than three (B þ CP) or more than two (B þ E) intracranial hemorrhages.

Results: In ﬁrst-line B þ CP cohort (n ¼ 67), 6-month PFS rate was 56.5% with a median PFS of 6.7 months [95% conﬁdence interval (CI), 5.7–7.1] and median overall survival (OS) of 16.0 months. Investigator-assessed overall response rate (ORR) was 62.7%: 61.2% in intracranial lesions and 64.2% in extracranial lesions. Because of low enrolment (n ¼ 24), efﬁcacy results for the second-line B þ E cohort were exploratory only; 6-month PFS rate was 57.2%, median PFS was 6.3 months (95% CI, 3.0–8.4), median OS was 12.0 months, and ORR was 12.5%. Adverse events were comparable with previous trials of bevacizumab. One grade 1 intracranial hemorrhage occurred and resolved without sequelae. Conclusions: The BRAIN study demonstrates encouraging efﬁcacy and acceptable safety of bevacizumab with ﬁrst-line paclitaxel and carboplatin in patients with NSCLC and asymptomatic, untreated brain metastases.

The development of brain metastases is common in patients with advanced non–small cell lung cancer (NSCLC), occurring in 24% to 44% of patients (1–3), more frequently in patients with adenocarcinoma histology. Brain metastases often lead to deterioration in neurologic and neurocognitive function (1) and are associated with signiﬁcant morbidity (4), including a risk of spontaneous hemorrhage at a rate of 1.4% to 10% (average of 2% to 3%; ref. 5). The primary score used to predict prognosis of patients with brain metastases remains the recursive partitioning analysis (RPA) score, which splits patients into 3 classes (class 1: patients with Karnofsky performance status 70% and age
