Clinical and research applications of multiplexed immunohistochemistry and in situ hybridization

I’ve always been curious, with a need to be on the cutting edge of scientific innovation, so after a successful academic career I moved to the rapidly evolving world of biotech. A 15-year journey in this space ultimately led me to Ultivue, their novel InSituPlex® assay, and following advances in tissue multiplexing.

The brilliant Stephen Hawking once said that “The universe does not behave according to our pre-conceived ideas. It continues to surprise us.” The same statement is also true for how we think of the dynamic nature of the cancer universe, in particular the complexity of the tumor immune microenvironment (TiME/TMEs)- an ever-evolving rich milieu comprising of non-malignant immune cells, fibroblasts, adipocytes, extracellular matrix components and neuronal cell types.

GEN: If I were to design my own panel for immunofluorescence, what are the main considerations, given everything you’ve suggested during the webinar for validation? Angela: There are several things one needs to think about when you build a new panel for multiplexed immunofluorescence. You need to consider the abundance of the targets to be

It’s clearly a very timely discussion with many recent articles reviewing the complexities of the tumor microenvironment and overall tumor heterogeneity that have been implicated in late-stage clinical failures, underscoring an urgent need for tests that accurately predict response to the growing number of available therapies.

It was a record year of attendance at this year’s 37th annual SITC meeting. Whether reflective of waning new Covid cases from a peak in late January 2022, a new location, or merely the appetite to meet up with colleagues, check out new technologies or be part of important scientific discussions-Boston SITC had it all.

Adapted from a line in “Ode to a Mouse” from fellow countryman Robert Burns, the phrase, “the best-laid plans of mice and men often go awry”, indicate that no matter how carefully a project is planned, something may still go wrong with it unfortunately speaks to the reality of clinical trials for novel therapeutics, with approximately only 11% of drugs that begin phase I clinical trials eventually being licensed.

Despite advances in immunotherapy, it’s clear that only a minority of patients respond. Therapies that rely on immune activation, such as checkpoint inhibitors, have been shown to be especially difficult due to the complex and heterogeneous immune escape mechanisms which can develop in each patient. Clearly there’s much anticipation and focus on new contenders for successful combination checkpoint therapy.

I have learned in my career that there is a special recipe for making young companies successful. You need to have an amazing product that enables customers to accomplish their goals in a better way than their current method.
