Commentary on Science, Innovation & New Products with a focus on Oncology, Hematology & Cancer Immunotherapy

In the past, I’ve sometimes been accused of being a bit of an immunotherapy bear for my dislike of cancer vaccines as a single agent therapy in advanced disease where the tumour burden is very high. That particular field has undoubtedly been a huge graveyard for many companies, much in the same way that metastatic melanoma was, until novel therapeutics and immunotherapeutics emerged to push through the envelope.

To be clear, I am though, a big fan of targeted immunotherapies such as checkpoint inhibitors and chimeric antigen receptor (CAR) T cell therapies, which have been very much to the forefront in immuno-oncology over the last two years and rightly so, with some initial trials showing some very promising results.

Both of those approaches are squarely part of the adaptive immune system and seek, in different ways, to retrain the bodies immune system to fight the tumour. More recently, the innate immune system has seen new advances as reearchers moved beyond simple vaccines to develop more thoughtful and innovative approaches that seek to outwit the very masking the cancer is trying to fool the immune system with. It’s no less exciting, just a different way of looking at the science and improving out understanding of the biology of the many diseases that cancer makes up.

In this AACR preview, I take a broad look at some innovative and novel scientific approaches, including targeting anti-CD47 and SIRPα (Stanford and Stem Cell Therapeutics), KIR and MICA (Innate Pharma) and neutrophils (Biothera).

Beyond the noise of the exciting the data in CAR-T cells, CLL, NHL and multiple myeloma, one of my favourite pastimes at cancer conferences is to look out for up-and-coming gems in the poster halls.

By this I mean interesting novel targets or very active agents in the pipeline.

One of the most eagerly awaited targets on my list was the Killer Immunoglobulin-like Receptor (KIR). It may be a key part of overcoming lymphoma resistance and inducing cell death. If you don’t kill the cancer cells, you likely won’t see remissions occurring.
