Bevacizumab and Erlotinib in Lung Cancer With Brain Metastases, a Phase II Trial (BRILLIANT)

A Phase II, Open Label, Multicenter Study of Bevacizumab in Combination With Erlotinib Versus Erlotinib Alone in Patients With EGFR Mutant Non-small Cell Lung Cancer Who Have Brain Metastases

This is an open-label, randomized, multicenter phase II study conducting in 3 medical centers in Asia. Patients will receive erlotinib in combination with bevacizumab or erlotinib alone. This study will enroll EGFR-mutant NSCLC patients who have asymptomatic brain metastases.

The primary objective is to compare the systemic progression-free survival (PFS) to bevacizumab plus erlotinib versus erlotinib alone in patients with EGFR mutant NSCLC who have asymptomatic brain metastases.

Study Overview

• Status: Unknown
• Conditions: Carcinoma, Non-Small-Cell Lung; Brain Neoplasms
• Intervention / Treatment: Drug: Bevacizumab plus erlotinib; Drug: Erlotinib

Detailed Description

This is an open-label, randomized, multicenter phase II study conducting in 3 medical centers in Asia. Patients will receive erlotinib in combination with bevacizumab or erlotinib alone. This study will enroll EGFR-mutant NSCLC patients who have asymptomatic brain metastases.

The primary objective is to compare the systemic progression-free survival (PFS) to bevacizumab plus erlotinib versus erlotinib alone in patients with EGFR mutant NSCLC who have asymptomatic brain metastases.

Patients will be randomized, at a 1:1 ratio, into bevacizumab plus erlotinib group or erlotinib alone group. Compute tomography (CT) or MRI scans will be performed every 6 weeks in the first 12 months since start of investigational drugs, and then performed every 12 weeks. Patients will be followed until documented progression at brain and/or extra-cranial lesions. Patients with intracranial progression only are allowed to continue investigational drugs until a second progression of either intracranial progression or extracranial progression, developed, and the time-to extracranial progression will be determined. In patients with EGFR mutant advanced NSCLC who had brain metastases, it was reported that PFS to erlotinib or gefitinib was 6.6 months(Park et al., 2012). In the current study, it is assumed that the median PFS, both intracranial and extracranial included, is 7 months for erlotinib group alone and is 12.3 months for bevacizumab plus erlotinib group (hazard ratio 0.57) (Seto et al., 2014). 109 patients will be required for analysis in this randomized phase II study. Patients will be stratified according to the EGFR L858R mutation and the EGFR exon 19 deletion mutation.

Male or female sterilization or

Combination of any two of the following:

Use oral, injected or implanted hormonal methods of contraception. Placement of an intrauterine device (IUD) or intrauterine system (IUS). Barrier methods of contraception: condom or occlusive cap (diaphragm or cervical/vault caps) with spermicidal foam/gel/film/cream/vaginal suppository).

• Women are considered post-menopausal and not of child baring potential if they have had 12 months of natural (spontaneous) amenorrhea with an appropriate clinical profile (e.g. age appropriate, history of vasomotor symptoms) or have had surgical bilateral oophorectomy (with or without hysterectomy) or tubal ligation at least six weeks ago.

• Sexually active males must use a condom during intercourse while taking the drug and for 6 more months after stopping study drug and should not father a child in this period. A condom is required to be used also by vasectomized men in order to prevent delivery of the drug via seminal fluid.
• Any other condition that would, in the Investigator's judgment, contraindicate patient's participation in the clinical study due to safety concerns or compliance with clinical study procedures, e.g. infection/inflammation, intestinal obstruction, unable to swallow medication, social/psychological issues, etc.
