In Pharmaland it is frequently the case that once a target has been validated there’s always new developments in the form of novel agents that emerge, as well as emerging new related targets to consider.

Standing from the KRAS crowd

Here we combine an update on some new market entrants in the KRAS niche with an expert interview discussing how to address a known area of acquired resistance that has recently been highlighted.  Naturally, that also brings with it yet more novel targets and potential combination strategies that may need to be considered by players in this space.

Yes, KRAS G12C is now a rapidly evolving area with multiple players and many moving parts, whereas even just back in January this year many observers saw it as a three horse race – think again, it’s much deeper and broader than that somewhat naive hypothesis already!

As usual, we follow these races longitudinally with regular updates and explain why new scientific findings need to be considered if we are to make a difference in the clinic with future combination strategies.

Are you ready for the latest game of 3D chess?

Fall in Boston during the AACR-NCI-EORTC Triple meeting

After recent updates on targeting KRASG12C and HRAS, let’s not forget that there are plenty of other elements of the RAS pathway that can be considered, not least is upstream receptor kinases such as EGFR and sideways to SHP2.

What happens when those worlds collide?

Quite a bit it would seem.

If we want to seriously impact patient outcomes for the better then we need to explore rational combination approaches.

Here’s one way to do it…

Please note that this is an early target with not very many competitors, so there’s plenty that can happen here on multiple fronts!

Boston – One of the most enjoyable things about writing about science and early clinical oncology data is the relationships we build with thought leaders, such that they can be open and honest about their reactions, without them being judged, misinterpreted, or misquoted. We’re on a journey with them, whatever the ups and downs might bring, in a bid to capture the realities of the oncology R&D rollercoaster.

Don’t be fooled by the gloomy Boston weather as a metaphor for data presented at Targets19!

Each story becomes a snapshot in time, a short of ‘Kodak moment’, if you will.

Imagine then, capturing a discussion with a global lung thought leader discussing the initial data from the first-in-man trial with a KRASG12C inhibitor from Mirati (MRTX849) and his experiences in treating people with advanced lung cancer who have the dreaded KRAS mutation, which until recently there were no effective options for.

Thus, we captured the exuberance of seeing objective responses in patients for the first time, “It’s fantastic!” and at the same time qualifying that with a balanced and candidly objective perspective, “it’s still early days.”

Both are true, and not mutually exclusive.

In between these two extremes there is much to think about including understanding the inevitable resistance mechanisms that evolve (primary and secondary), figuring out how to optimize the combination trials as well as reactions to other, seemingly competitive, developments. Our expert in the hot seat today had some rather thought provoking ideas on these important topics to discuss that we wanted to share and stimulate some debate on.

Chicago – here we are with highlights and insights from Day 4 of #ASCO19 and time is running down on this meeting with just half a day to go – whew!

One of the highlights of medical and scientific meetings we go to is meeting early career researchers, especially those who are doing translational research.

On Monday at ASCO19 we particularly enjoyed talking with Dr Wungi Park (@W_Park_MD) from Memorial Sloan Kettering Cancer Center who presented a poster on homologous recombination deficiency (HRD) as a biomarker in pancreatic cancer (abstract 4132).

We look forward to hearing more from him and colleagues as data is generated from the clinical trial they plan to start later in this year to investigate this further. Translational research in action!

What were some of our other highlights of Manic Monday at ASCO19? We’ve shared a few in the post below for BSB subs.

Henry Moore sculpture – looks like a protein binding pocket!

Cambridge, UK – It’s somewhat ironic that we headed across town today to chat with one of the world’s leading cell biologists on MYC and RAS with a post on KRASG12C inhibitors almost ready in the bag. More on that interview in a future mini-series.

There are a number of nuances and subtleties involved in this niche, which have been somewhat lost in the frantic hype over hope melêe of late.

This review is a long and thorough one and perhaps rather contrarian in nature.

That said, I do feel that it is very important to highlight a lot of issues that are being ignored in the rush to declare the latest expected winners and losers or even potential blockbusters, if the breathless signals are to be believed.

If nothing else, there are certainly several key issues that could have a bearing on the clinical results in patients that are worthwhile highlighting for discussion and adding to the watch list because some of these factors may well take time to develop.

This is one of those ‘Ground Control to Major Tom – take your protein pills and put your helmet on’ moments… Actually, I may well be needing the helmet as protection if the analysis and commentary turn out to be unpopular!!
