It’s Day 7 of our 12 day Countdown to AACR 2016 in New Orleans. After exploring GITR and OX40, we’re now looking at another stimulatory target for cancer immunotherapy: CD40.
Anti-CD40 antibodies are agonists that act on stimulatory signalling receptors on T cells and antigen presenting cells (APCs). Targeting CD40 effectively acts to “put the foot on the gas” and may help generate a better immune response. This could be important in cancers that have fewer natural T cells present.
CD40 is an attractive target because it’s expressed in more than 50% of carcinomas and melanomas and almost all hematological B cell malignancies. Of particular interest is the potential to combine a CD40 agonist with a PD-1/PD-L1 checkpoint inhibitor.
Multiple companies have CD40 agonists in clinical development including Roche, Apexigen, Alligator Biosciences and Seattle Genetics. There are others coming too.
In this preview of AACR 2016, we’re looking at the CD40 landscape. New products and companies have entered the scene, so we’re highlighting them and some of the CD40 presentations to look out for at AACR 2016 (and why they matter).
