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

Barcelona – It seems only in only four years we have gone from discussing the phase 1 osimertinib data in EGFRm lung cancer with one Boston expert to reviewing the survival data from the phase 3 study with another expert from the same city… how time flies!

Today was a crazy day with multiple different embargoes lifting at different times so to make things simpler we carved out three different tracks to make it easier for readers to focus and follow the stories they are most interested in.

The KRASG12C clinical trial readouts continue apace with a look at the new non-lung cancer data. That post already went live at 1.30am ET if you’re looking for that evolving story.  The main highlights post with a daily running live blog and multiple updates throughout the day can be found here.

Meanwhile this particular post will contain everything related to osimertinib and the FLAURA trial, as well as where we are on uncovering resistance mechanisms. To get started we have a new press release to look at as well as some independent expert commentary to put the data in context.

Over the last decade we have seen some real progress with some subsets of lung cancer, particularly in EGFR mutated and ALK translocated tumours.  Indeed, an incredible amount of translational work has emanated from just a few groups based in Boston, New York and Hong Kong.

At AACR earlier this year, Dr Jeffrey Engelman (MGH, Boston) gave a fantastic talk not just about heterogeneity, resistance mechanisms, but also on how lung cancer can transform. Included in his review was the role of biospies and how he sees those evolving.

I’ve been meaning to write up this important talk since April, but decided to wait until the key publications that were in press at the time were actually published – it was a longer wait than expected!

In general, it is our policy to write up published, rather than unpublished data, out of respect to researchers.  It also makes it more useful to readers when the translational and clinical data is publicly available for those interested in reading the in-depth research articles.  We also gathered commentary from other though leaders in the lung cancer space for some additional insights.

The ASCO 2014 season kicks off with the release of the embargo on main abstracts (other than the late breakers and plenary sessions) yesterday evening. Over the next week, I’m planning to cover some of the highlights (positive and negative) that I found interesting or worthwhile discussing. While there was nothing particularly earth shattering or new in the press briefing at lunch time yesterday, that’s not to say there aren’t some important data this year buried amongst the 5000+ abstracts.

Today I’m driving to Orlando and on Friday will be at the American Urological Association (AUA) meeting, so a lighter post will appear here on BSB regarding my initial topline highlights and lowlights tomorrow.

I decided to kick off the ASCO Previews first and focus on an altogether different topic, one that we’ve covered longitudinally on either PSB and BSB – originally with some scientific and translational data – and now with some initial clinical trials that look pretty encouraging thus far. The bench-to-bedside transition is often fraught with many challenges, but occasionally, they actually turn out quite well in practice.

In the second part of our mini-series on immuno-oncology, I thought it would be a nice idea to share a recent interview conducted with one of Roche/Genentech’s leading researchers in this field.  I was particularly interested in their approach because while BMS and Merck have clearly focused on anti-PD-1, Roche and Genentech have effectively zigged with their development of an anti-PD-L1 inhibitor.  Does this matter?

Here, we explore the general background to this approach and, in particular, where the company are going with their anti-PD-L1 inhibitor, MPDL3280A.

Topics discussed:

anti-PD-L1, anti-PD-1, anti-CTLA-4, checkpoint point inhibitors, T cells, biomarkers.

Drugs mentioned:

MPDL3280A, nivolumab, MK-3475, ipilimumab (Yervoy), lirilumab, BMS-986016 (anti-LAG3), bevacizumab (Avastin), erlotinib (Tarceva), vemurafenib (Zelboraf), cobimetinib.

If you are interested in more background on how the PD-1 and PD-L1 inhibitors work, you can check out the mechanism of action (MOA) in our video preview from ASCO last year, which explains this in fairly simple terms.
