Description:Etrumadenant (AB928) is an orally bioavailable, selective dual adenosine receptor (A2aR/A2bR) antagonist. Etrumadenant relieves adenosine-mediated immune suppression. Etrumadenant has immunomodulatory and antitumor activities.

In Vitro:In human in vitro cell cultures, moDC differentiated in the presence of adenosine showed a decreased ability to stimulate IFN-γ secretion from allogenic CD4+ T-cells in a MLR. This suppression is significantly reversed by addition of Etrumadenant. Multiplexed gene expression profiling using NanoString identified a cassette of 39 genes that are regulated by adenosine during moDC differentiation. Etrumadenant shows rescue of these gene expression changes[2].

In Vivo:Concurrent treatment with Etrumadenant and chemotherapy results in significantly reduced tumor volume in vivo using AT3-OVA tumors; Similar results are observed for the combination of Etrumadenant and NSC 266046. AB928 is also capable of suppressing growth of B16-F10 tumors both as a single agent or in combination with α-PD-1 therapy. Etrumadenant increases the antitumor immune response leading to suppressed tumor growth and increased immune cell infiltration in mouse syngeneic tumors[2].

This suppression is significantly reversed by addition of Etrumadenant. Multiplexed gene expression profiling using NanoString identified a cassette of 39 genes that are regulated by adenosine during moDC differentiation. Etrumadenant shows rescue of these gene expression changes[2]. MedChemExpress (MCE) has not independently confirmed the accuracy of these methods.
