AACR 2017 Preview 8

Molecular biology was a hot new topic back in its infancy in the late 1980’s just as I was finishing my doctorate – cue moment of realising you’ve missed a big wave before it really even started!

These days scientists now delve in the realm of deeper molecular biology and go much further than mere genes… it’s all about transcription factors, super enhancers, chromatin complexes, bromodomains, and even chromodomains. In the past, many of these drivers were often considered ‘undruggable’ – think MYC or RAS, for example.

The world of molecular biology is rapidly changing as researchers understand pathways and processes associated with carcinogenesis better, thereby enabling new approaches to evolve and with it, valid new targets for therapeutic intervention.

This field is always one of my favourite ones to cover at AACR, where we not only learn about exciting new research from investigators, but also up and coming young biotech companies that are doing good work who deserve to be highlighted.

Targeting MYC – the undruggable protein – or is it?

Have you ever sat in a freezing cold scientific session and been so engrossed in the compelling presentations that followed, you simply forgot to take notes? Not one. That actually happened to me at the American Association for Cancer Research (AACR) in Philadelphia this year in one of the many fringe sessions that I attended.

Granted, the hot topic of the conference was undoubtedly checkpoint inhibition, but I was anxious to escape to the comfort of some meaty and familiar basic and translational science, namely MYC.  MYC is largely thought to be a difficult to target, even undruggable protein, and along with RAS and p53, represents a formidable challenge for cancer researchers.  These three oncogenic proteins alone are probably responsible for more drug resistance developing and even death from cancer than any other proteins in a patient with advanced disease.

For cancer patients with advanced disease, the clock is ticking on time they have left.

Solve these three problems (MYC, RAS and p53) and we may have a shot at dramatically improving outcomes. As Dr Gerard Evans (Cambridge) noted:

“I think it’s fair to say that we don’t really know why interruption of any oncogenic signal actually kills cancer cells, but one of the reasons that we’re interested in MYC is because it seems to be a common downstream effector of many, maybe all cancers.”

Sure, the road to success is paved with an enormous graveyard of failures, just as metastatic melanoma was before checkpoint blockade came along, ironically.  What I heard at AACR both inspired and filled me with greater confidence… we’re finally getting somewhere.

How Syros are changing biotech R&D

We have written about small biotechs and big pharma a lot on this blog, particularly when they have exciting new developments in their pipeline to review and consider.  Increasingly, we have also begun to look at the early phase companies because often, that is where some fresh ideas and approaches are being developed and tested.

They’re also not beholden to the norm in terms of thinking that’s non-linear and many are academic start-ups that began life as thought leaders doing their own research and eventually VCs get interested, enabling financing to be raised.  The downside of this for some of our readers is that they’re usually not investable as a private company (sorry about that), but we have a broad church here on BSB and instead these small companies attract the interest of enlightened pharma companies who want to license early compounds in areas they are interested in or gain knowledge about a new field of research before buying elsewhere.  In other cases, the approach pays off in clinical trials and we see the IPOs emerge from companies such as Juno Therapeutics.

Syros Pharma LogoOne company that neatly fits this bill is Syros Pharmaceuticals, an academic spin-off from the Whitehead Institute of MIT and Dana Farber Cancer Institute in Boston based on the pioneering work of Drs Richard Young, Jay Bradner and Nathanael Gray.

Regular readers will remember our original article their the scientific work on gene transcription factors at AACR last year, which included a fascinating interview with Dr Young.  That was probably one of my favourite interviews of 2014 – I was inspired!

NancyHS201303wsdIt’s now time to look at the company and entertain some strategic thinking about where they’re coming from and where they’re going with clinical development.  The CEO, Dr Nancy Simonian, kindly agreed to an interview and be put in the ‘hot seat,’ so to speak.

This screenshot from the Syros website sums up their philosophy: Better medicines through gene control.

Super Enhancers – what are they and why do they matter in cancer research?

Sometimes you get lucky before a conference and catch an interview with a thought leader ahead of time when it’s more relaxed and less fraught with all the demands of meetings etc while there.

That good fortune happened to me on the Friday before the recent AACR conference in San Diego, when I recorded an interview with Dr Richard Young, (Whitehead Institute & MIT and scientific co-founder of Syros), who was giving a plenary talk on the Sunday at AACR entitled, “Transcriptional and Epigenetic Control of Tumor Cells.”

Epigenetics and transcriptional changes are fascinating concepts to me because they get right to the heart of what’s going on deep in the oncogenes and how they control processes in cancer. Clearly, in simplistic terms, if we can understand how things change and evolve, then we can potentially devise better strategies to overcome them. Instead of targeting a protein kinase with a small molecule or a cell surface antigen with a monocloncal antibody, this is an altogether different approach. Protein-protein interactions such as MYC, RUNX1, p53/TP53 etc have long been the bugbear and frustration of many good researchers, precisely because they are challenging to target with conventional approaches.

So what’s new and why am I really excited about these new developments?
