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

For the final postcard in our 2020 summer mini-series on the potential of immunometabolism in oncology R&D, we’re taking an in-depth look at the ways in which metabolic programming can overcome immunosuppression in the tumour microenvironment (TME), as well as looking at additional novel ways in which the fitness of T cells can be impacted.

We’ve already covered glutaminase, arginine, p38 and others, yet there are other metabolic effects to consider too, as we discover in our latest expert interview.  In the penultimate postcard, we looked at mitochondrial phenotypes and how they can impact both mitochondrial and T cell fitness, which are important aspects in making adoptive cell therapy (ACT) based approaches such as TILs and CAR-T cell therapies more effective.

Deep thoughts on immunometabolism and how it can impact antitumour response

These themes show up yet again, but in a rather different context because T cell fitness can also impact immune checkpoint blockade, oncogenic targeting, as well as transcriptional and epigenetic approaches.

As much as we have been slowing building up the evidence during this series, in the finale it’s now time to kick up things up a notch or two and draw some unifying ideas together.

We accomplish this feat with a rising young star in this particular niche, Dr Ping-Chih Ho, who is at the University of Lausanne.

He kindly spoke to BSB about his pioneering and prolific research, some of the critical questions he has sought to answer, plus what he sees are important future directions to consider in metabolism research.

One only has to look at the number of clinical trials to recognize that cell therapies are one of fastest growing areas in terms of cancer new product development.

Over the past several years we’ve seen many changes and improvements in continuous innovation regarding the development of CAR T cells.

What metabolic “treats” do T cells like?

There has been no shortage of novel ways to enhance their targeting, durability, efficacy, or ease of administration. Most of the early strategies have yet to translate into commercial products, but it remains an area an attractive area to investors hoping to repeat the returns seen with Juno and Kite as more competitors enter the field.

In the fifth post in our mini-series on novel approaches in the emerging immunometabolism niche, we’re looking at ways to metabolically reprogram CAR T cells, as well as what the future may hold for the next generation of CAR T cells in this context.

Like a postcard from one’s summer holiday, it’s an opportunity to offer a snapshot at a moment in time from our journey.

We were fortunate to have the opportunity to talk with a researcher who is actively at the forefront of this area. Dr Roddy O’Connor is working with Carl June along with various colleagues at the University of Pennsylvania, and he kindly spoke to BSB about his work.
