Updated data are often presented at conferences and therefore the results can differ from the submitted abstracts, which are sometimes submitted as placeholders based on immature data cutoffs. That was certainly the case in several examples at the ASCO GI conference in San Francisco last weekend.

San Francisco HerculesAfter Monday’s look at new developments in the lower GI tract, we now turn our attention today to the upper GI tract with a focus on oesophageal, gastric (stomach), and gastro-esophageal junction (GEJ) cancers.

Over the last five years we have seen new approvals for targeted therapies such as HER2+ gastric cancer and relapsed refarctory gastric cancers with a VEGF inhibitor. Will that trend continue over the next five years or will we see new approaches such as immunotherapy enter the market and dominate?

We’ve had a couple of requests come in for a revival of the old conference series… ‘Gems from the poster halls’ because quite a few folks are interested in the up and coming data from small to medium biotechs.

SABCS San Antonio CrowdA bunch of my Post Doc chums in this field were at the San Antonio Breast Cancer Symposium (SABCS) meeting and gleefully highlighted mobbed posters or areas where they thought the data looked potentially interesting.

From these, we selected a few for review in today’s look at the nuggets that can be gleaned from cool and intriguing trials or preclinical research that may influence future trials.

Companies covered in this article include Seattle Genetics, Jounce, Immunomedics, Syndax and MedImmune.

Today the immunotherapy and related data flooding out of the annual meeting of the San Antonio Breast Cancer Symposium (SABCS) is pretty exciting!

Data was presented on a number of drugs including pembrolizumab, avelumab and atezolizumab, which put together with some recent publications, highlights some potentially exciting opportunities in this fast moving space.

Here, we explore the potential for checkpoint therapy combinations in TNBC, HER2 and even the ER+ subsets.  There’s a lot of new findings to take in and contemplate here.

One area that is finally seeing a lot more research results of late is neo-adjuvant therapy in breast cancer, i.e. therapeutic intervention prior to surgery.

The main advantages of neo-adjuvant over adjuvant therapy are:

  1. If it works, then the therapy allows the margins to shrink prior to surgery, potentially making the tumour easier to excise
  2. If therapy works prior to surgery, you know what will likely be effective post surgery, whereas in adjuvant treatment after surgery, this is unknown.

One of the leading trials for neoadjuvant breast cancer was the ISPY2 (Investigation of Serial studies to Predict Your therapeutic response with imaging and molecular analysis 2) study.  I wrote about it in more detail at the time it was launched on Pharma Strategy Blog, if you need more information. Basically, the study is based on a complex adaptive conjoint design in neoadjuvant breast cancer, so over time, additional arms were added to the study (there were originally four) while others were removed. In this way, the investigators can find the best therapies for each tumour subtype (HER2+/1, ER+/- or triple negative) based on the responses and biomarkers.

It’s been a long 14+ hours here on the first day of ECCO in Amsterdam and I’m starting to flag a little. The fun part of being in Amsterdam is renting an apartment, living like a local and cycling to/from the conference centre on rickety Dutch bicycles!

That said, having been aghast at the poor wifi and frustrated with nearly not being allowed in a key session over badge confusion, plus scheduling of multiple key sessions at once, we decided to make the best of it and be selective. This morning, for example, I ran from lung to melanoma to breast to the  poster hall and back again to a lung session. Pieter had the luxury of enjoying the prostate cancer session in comparison!  By 6pm the BMS corporate symposia on immunotherapy was out – the brain was dazed and jetlagged, the car needed fuel (preferably of the rocket variety) and also a glass of wine!

We will post some more detailed notes later, but today I wanted to offer some top line thoughts on some of the highlights:
