Sarcoma is something we call one disease but actually represents 50-70 different histologies, which poses challenges for drug development.  Not only do you have to identify what’s the unique target, but it’s hard to accrue patients into trials, when a major center may only see a few of each sub-type.

Soft tissue sarcoma is an area of unmet medical need, and one I have been interested in since launching Gleevec in GIST (way back when) when I was fortunate to get to know many of the leading sarcoma experts.

One of these is Dr George Demetri, who is Director, Center for Sarcoma and Bone Oncology at the Dana-Farber Cancer Institute and a Professor of Medicine at Harvard Medical School.

At the recent European Cancer Congress in Vienna, I had the privilege to talk with Dr Demetri about some of the latest research in soft tissue sarcoma.

We spoke about cancer immunotherapy, new small molecules and monoclonal antibodies, and the potential of targeting the epigenetic machinery.

A lot of what Dr Demetri is doing is currently “under the radar” and while he didn’t give any secrets away, he did give some sense of where some breakthroughs may occur in the not too distant future.  He also talked about how sarcomas with a specific target can be used for proof of concept clinical trials of novel agents.

Given the pressure that many companies are under to speed up their path to market strategies, accelerated approval in a rare tumour subset is one approach that can be considered.

It’s an exciting time in the field with the potential for several agents in development to move the needle and make a difference. I hope you enjoy this post, it was a real pleasure to talk with Dr Demetri again.

Many years ago, I used to work in the sarcoma and GIST space, which is a very interesting and fascinating disease to explore from a biology perspective. There are many different subsets of sarcoma, several different histologies, as well as numerous targets such as KIT in gastrointestinal stromal tumours (GIST). Some of these subsets are sensitive to chemotherapy such as doxorubicin, while others such as GIST are sensitive to targeted therapies including imatinib, sunitinib, regorafenib etc. Imatinib (Gleevec) is particularly effective in GISTs with exon 11, while the less common exon 9 has been shown to be more sensitive to sunitinib (Sutent), for example.

Often pharma companies will work with the Sarcoma Alliance for Research through Collaboration (SARC) cooperative group to undertake a phase 1 allcomers trial to evaluate which subsets might be appropriate for a given therapy, before exploring a narrower inclusion/exclusion criteria in a larger phase 2 or 3 study.  You can check out their current clinical trials in sarcomas here.

Overall, people with malignant sarcomas tend to be seen by specialist centres where there are usually clinical trials available, representing a way to determine which of the agents in development are superior to the current standard of care.

One of my favourite moments at ASCO this year was escaping the heavily mobbed poster halls to sit down for a quiet ‘fireside chat’ and catching up with an expert in this field to learn more about the latest new developments in sarcoma.

I’m delighted to publish another thought leader discussion today on Biotech Strategy Blog (BSB), where we have an in-depth interview with Dr Margaret von Mehren, the Director of Sarcoma Oncology at Fox Chase Cancer Center.  She has spent spent her career trying to identify new therapeutics for gastrointestinal stromal tumours (GIST), as well as soft tissue sarcomas (STS).
