Is the dragon roaring back?
It’s a while since we last looked at new developments in a rare group of cancers called sarcoma so this is a good time to stake stock and explore the positive and negative trial results, as well as look at some of the emerging targets that are being investigated.
Not all of them will likely pan out given the nature of the disease, but some might turn out to be hidden gems.
We’ve had a few negative trial readouts in sarcomas and plenty of new trials with a variety of agents in early development – is the dragon roaring back or whimpering?
Aside from our top 10 review, we also have a thought leader interview to share with commentary from a sarcoma specialist…

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.
Dr Margaret von Mehren
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).
