Glasdegib for the treatment of acute myeloid leukemia.

INTRODUCTION

Over the last few years, substantial progress has been made in the management of acute myeloid leukemia (AML). The first changes in the management of AML date back to last 2000s with the advent of hypometilant agents, later with Bcl2 inhibitor venetoclax, and Fms-like tyrosine kinase 3 (FLT3) inhibitors (midostaurin and gilteritinib), and more recently with IDH1/2 inhibitors (ivosidenib and enasidenib) and the hedgehog (HH) pathway inhibitor glasdegib.

AREAS COVERED

Glasdegid, formerly PF-04449913 or PF-913, acts as a smoothened (SMO) inhibitor and has been recently approved in combination with low-dose cytarabine (LDAC) by FDA and EMA for the treatment of naïve AML patients unfit for intensive chemotherapy.Several studies have explored the efficacy and safety of glasdegib, as a single agent or in combination with other drugs, in both the setting of relapsed/refractory and naïve AML patients, confirming its efficacy in controlling disease and safety profile.

EXPERT OPINION

All these trials suggest that glasdegib seems to be an ideal partner for both classic chemotherapy and biological treatments (such as therapy with FLT3 inhibitors). Further studies are needed to better understand which patients are more likely to respond to glasdegib.
