Phase I Study of Adavosertib with Radiotherapy and Temozolomide in Newly Diagnosed Glioblastoma and Intratumoral Drug Levels in Recurrent Glioblastoma.

ABSTRACT:

Purpose

Adavosertib is an oral small-molecule inhibitor of Wee1. The Adult Brain Tumor Consortium conducted a phase I study evaluating adavosertib in combination with radiation (RT) and temozolomide (TMZ) in patients with newly diagnosed glioblastoma (GBM), as well as a surgical window-of-opportunity study in recurrent GBM.

Patients and methods

The MTD of adavosertib was determined in adult patients with newly diagnosed GBM using a standard 3+3 design in two separate cohorts: with concurrent RT/TMZ or with adjuvant TMZ. A combination cohort with both concurrent and adjuvant adavosertib at MTD followed. We also performed intratumoral drug distribution studies in patients with recurrent GBM undergoing surgery.

Results

As separate cohorts, the MTD for concurrent adavoser
