Dr Jackie Fairley, Starpharma CEO, commented: “We’re pleased to see the ongoing progress of the AZD0466 trial. It is exciting to have this highly novel DEP®-based product being made available to patients at this leading international cancer center.” About AZD0466 AZD0466 is a dendrimer-based formulation of a novel dual Bcl2/xL inhibitor developed under Starpharma’s multi-product DEP® licence with AstraZeneca. AZD0466 utilises DEP® to improve the formulation characteristics and therapeutic index of the anti-cancer agent and is currently in a phase 1 trial in the US. AZD0466 is described as having the potential to be a ‘best-in-class’ agent with a broad opportunity in solid and haematological tumours (blood cancers) due to its ability to target both Bcl2 and Bcl/xL. AZD0466 has demonstrated excellent anti-cancer activity in a wide range of preclinical tumour models including Acute Myeloid Leukemia (AML), Acute Lymphoblastic Leukemia (ALL), Non-Hodgkin’s Lymphoma and Small Cell Lung Cancer (SCLC).
