You see a dry cleaners, I see a gelato shop in San Diego (yes, really)

Lately the cancer research space is abuzz with the promise of several novel therapeutic approaches, each touted as the next speculation akin to gold panning or tulip mania in centuries past.

As the field rapidly expands, a couple of nagging questions emerge:

  • Can the market truly support the sheer volume of agents now in development?
  • What does success in this particular niche actually look like?

The issue extends far beyond the usual breathless hype and headlines. The reality is many smaller biotechs are on a collision course with a ‘day of reckoning’, as the large pharma players inevitably shift their focus either to snapping up the cream of the crop and through their resources as clinical development or seek fresher opportunities. The unforgiving nature of this ecosystem is nothing new, of course. Yet the current scale of the current pipeline frenzy is truly staggering.

Amidst this frenetic activity, however, glimpses of genuine innovation manage to cut through the noise. The latest dataset from the AACR annual meeting provides a window into some of the more novel strategies taking shape in early stage research. While the hype around certain candidates may be getting ahead of the data, the insights reveal both the promise and potential pitfalls of this highly competitive therapeutic landscape.

As the field continues to evolve at a breakneck pace, discerning fact from fiction will be essential. Mere incremental advances will struggle to capture and hold attention for the long run and, more importantly, investment in an environment hungry for promising agents to fill aging pipelines with gaps coming up thanks to loss of exclusivity.

The thing is, it’s easy to forget only the most compelling, well-differentiated approaches will be poised to navigate this tricky terrain successfully…

Fall Colors in Boston

The Fall cancer conference season is in full swing with the TARGETS and ESMO23 meetings both coming up this month.

Here we take a look at what to watch out for in both small and ‘large’ small molecules these include various epigenetic targets, KRAS, and SHP2.

The headline for today’s post was inspired by a British TV sitcom from the 1980s, which kind of reminds me of how perception of many of these targets has changed over time…  as in time went on, in ever decreasing circles, the hype wore off and despair sets in.

Of course, there’s always redemption down the road in some form or other, as illustrated by the Fall and Rise of Reginald Perrin.

In this case, as the lustre fades on some of the frontrunners there’s now a rising tide of different – yet related – targets, as well as new compounds and combinations coming through – what’s not to like?

Orlando – AACR23 is in full swing and one of the areas gaining a lot of attention at the meeting is a surfeit of new data on targeting KRAS.

In this post we review some of the key data presented so far, along with commentary from some of the education sessions we’ve covered, which not everyone may have attended.

Can we beat KRAS and, if not, what are the challenges to be overcome? How should we go about this endeavour?  Is it all sun and palm trees in Florida?

Et tu, Brutus?

Perhaps the most controversial readout from ESMO22 this week was the phase 3 readout on Amgen’s pivotal trial for their KRAS G12C inhibitor in second line non-small cell lung cancer (NSCLC).

Instead of being an obvious shoo-in, quite a few surprising issues came to the fore – almost in a perfect storm fashion – acting to hobble the results in an unexpected fashion.

Here we review the issues and challenges facing sotorasib and also explore the potential impact on the field at large…

It seems astonishing to realise only a couple of years ago KRAS was considered undruggable intractable and here we are, not only with one drug approved, another filed and veritable long list of fast followers, but a whole ecosystem of different agents vying for a place at the table.

The wonderful news is we are starting to think more broadly about life beyond G12C mutations, not only with different combinatorial approaches, but also also in the context of how to tackle other related mutations as well.

Here, we wanted to explore the evolving universe more broadly and assess criticality as well as applicability – which agents might shine tomorrow if clinical data turn out positive?  The simple answer is more than you know.

So just who are the rising stars in this emerging landscape and what can we learn about them?

Be warned in advance – this is one of our longest and most comprehensive reviews on BSB with over 30 compounds highlighted in different guises, so grab a cup of Joe and be prepared to come with an open mind…

A bright future ahead or early warning signs?

It’s time for another update on the KRAS and SHP2 niches… it seems this space is much faster moving than our previous quarterly rolling updates in the past on other areas such as T70M in EGFR mutant lung cancers, checkpoint blockade in NSCLC, or new developments in CAR-T or CLL/iNHL.

It’s a sign of the modern times.

There’s always new entrants, new science and new clinical data to learn more about so without much further ado, let’s roll…

A graceful white swan serving as an antidote the current COVID19 pandemic (black swan event)

In our the third of our AACR 2020 Preview series, we turn to the KRAS pathway to look at some new aspects, whether they be new targets, novel agents in development or even twists on the biology of the disease.

There’s quite a bit to discuss here, certainly more than I was expecting considering it was expected to be a down year by some after all the excitement of last year’s revelations and developments in the clinic!

As we continue to follow the emerging KRAS niche longitudinally, we can easily imagine the kind of roller coaster ride that ensues with new product development in oncology R&D.

Early last year we posted an interview with Mirati’s CEO, Dr Chuck Baum, discussing their selective KRASG12C inhibitor.  A year on much has happened in the intervening time – additional competitors and potential collaborators have entered the clinic, a few mechanisms of resistance identified, and numerous combination partners have been suggested.  The company have also aired their own phase 1 data and new trials are expected to open during 2020.

This time around we talk to both Dr Baum and the company’s CSO, Dr James Christensen, about their experiences in the front line in terms of translating the preclinical data into clinical trials, their thoughts on important scientific data as well as the competition, and what to watch out for going forward.

This field is going to not only go fast judging by the emerging research published to date, but it’s also going to get way more complicated than many observers realise.
