In this episode, she describes three key challenges in immuno-oncology development related to anatomic pathology in immuno-oncology development related to anatomic pathology. Some of the key challenges that we see as an organization supporting clinical trials in the development of these, particularly with the context of companion diagnostics, is to ensure that the sample availability is adequate and appropriate for the different clinical trials and ensuring that the assay outcome is useful and the results are relevant for the clinical trials... And tissue samples ... as you know tissue has always been the issue and having adequacy of samples is one of the most critical components. It's also important that the sites that are sending samples have the ability to process samples in a timely manner, ensuring that the fixation and other pre-analytical conditions that influence the outcome of the results are well evaluated. Dr. Krishnan lays out a vision that will make the whole process easier for patients and doctors alike.
