Abstract
INTRODUCTION: Wee1 kinase controls the G2-M checkpoint. Wee1 inhibition by AZD1775 allows cells with a deregulated G1 checkpoint to progress, resulting in catastrophe and apoptosis. The challenges ahead are in the establishment of the optimum dosing schedule either alone or in combination, and the identification of patients with specific biomarker profiles who benefit most. Areas covered: This article provides an overview of AZD1775, based on English peer-reviewed articles on MEDLINE. The authors highlight the data from the published preclinical and clinical studies. Expert opinion: A majority of the current clinical trials focus on AZD1775 combined with chemotherapy or radiation. Treatment with AZD1775 was tolerated and antitumor activity has been observed, especially in patients with advanced malignancies harboring G1 checkpoint aberrations and/or DNA damage repair defects. Thus, identification of the molecular subtypes that benefit most from the treatment with AZD1775 alone or in combination may provide a novel strategy for cancer therapy. Research is needed for devising regimens to explore AZD1775 in combination with biologically targeted agents and/or immunotherapy (low dose versus high dose, intermittent versus continuous, sequential versus concurrent, etc.) for identifying potential biomarkers predictive of response and survival.
