Abstract

BACKGROUND: This study is a phase II clinical trial to evaluate the efficacy, safety, and tolerability of the blood-brain barrier (BBB) permeable peptide-paclitaxel conjugate ANG1005 in patients with recurrent high-grade glioma (HGG) (NCT01967810).

METHODS: Seventy-three patients were enrolled in 3 separate arms-recurrent glioblastoma (GBM) (Arm 1), bevacizumab refractory GBM (Arm 2), and grade 3 anaplastic gliomas (AGs) (Arm 3). The study was started in October 2013, and the data were locked on September 29, 2017. Safety was evaluated for all three arms ( n  = 73), and the primary endpoint for Arms 1 and 3 was objective response rate (ORR), and Arm 2 primary endpoint was progression-free survival rate at 3 months (PFS3).

RESULTS: Overall, the safety of ANG1005 was found to be consistent with a taxane toxicity profile. Otherwise, the primary efficacy endpoints of ORR and PFS were not met. The most common adverse events (AEs) were hematologic (32.9%), alopecia (31.5%), and fatigue (30.1%). The median PFS was 1.4 months (95% CI: 1.4, 2.1) and similar across all the treatment arms. The median overall survival was 13.4 months (95% CI: 3.4, 14.6) in Arm 1, 5.8 months (95% CI: 1.9, 9.7) in Arm 2, and 18.2 months (95% CI: 10.7, 35.3) in Arm 3.

CONCLUSION: A dose of 600 mg/m 2 was determined to be safe in this study. However, the primary efficacy endpoint was not met in the NCT01967810-ANG1005 trial, and no further studies are planned in the glioma setting with this compound.
