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

Tropomyosin receptor kinase (TRK) inhibitors are not a name that rolls off the tongue easily and yet this niche is attracting a lot of interest from observers curious to learn more about a highly targeted approach to rare oncogenes such as TRK, ROS1 and ALK that occur in several different tumour types.

Much of the focus has been on the more commonly expressed ALK-positive lung cancers with crizotinib, ceritinib, alectinib, brigatinib, lorlatinib and others. Crizotinib also targets ROS1 and is approved by the FDA in metastatic NSCLC whose tumors are ROS1-positive.

As the next part of the development in this sphere, TRK and ROS1 mutations are now in the spotlight. Indeed, we have been reporting on the data since 2014, which has been encouraging thus far, particularly from two companies, namely Ignyta and Loxo Oncology.  These two agents differ in that entrectinib targets TRK/ROS1/ALK whereas larotrectinib is a specific pan TRK inhibitor.

There was a new raft of data at the recent AACR annual meeting and more data is expected at the forthcoming ASCO conference.

Here, we take a look under the hood through the lens of one of the small biotechs in this space via a candid interview with Ignyta CEO, Dr Jonathan Lim.

With the sheer breadth and depth of immuno-oncology data being presented at even the American Association for Cancer Research (AACR), several readers were prompted to write in and ask:

“Is this the end of the road for TKI therapies? Should we even bother to continue working on these agents?”

Good question.

There was actually quite a bit of interesting data on regular novel targeted therapy to discuss, although I do concede that much of the mass media news focusing on the immuno-oncology tsunami in Philadelphia effectively drowned out targeted therapies and the results coming out in that space.

Reading Market Philly Chocolate TowerTo maintain the balance between novel targeted agents and immunotherapy, here’s a review of some of the interesting new developments that I came across at AACR, from both the poster halls, as well as some of the thought leaders in this space.

When you stack up the emerging evidence in several tumour subsets, there are quite a few tasty morsels that are worthy of further discussion!

I’d like to take this opportunity to extend a warm welcome to all the new subscribers who took advantage of the AACR Special Offer to continue their education and learning about the exciting new developments in cancer research.  Thank you for joining our conference coverage service, we really appreciate it.
