“Treating patients with glioblastoma with unmethylated MGMT promoter is particularly challenging. These tumors are inherently resistant to the temozolomide, which alkylates DNA at the O - 6 position of methylguanine, and is readily repaired by MGMT. VAL - 083 has been shown to be safe and may provide a valuable treatment option for these patients” - 1 “We agree that we desperately need something better to offer our patients and we feel that VAL - 083 has some promise and potential” - 2 Copyright 2019, DelMar Pharmaceuticals All rights reserved 9 Biomarker Enriched Patient Population 1.
