Immuno-Oncology Studies: Optimizing Design, Recruitment and Execution

The rise of immunotherapy has been meteoric — there are now well more than 1,000 Purple DNA Strandimmuno-oncology (IO) trials ongoing according to clinicaltrials.gov. Finding and enrolling the appropriate patients for these potentially revolutionary treatments has presented a profound challenge, one that was recently covered in the aptly titled New York Times article: A Cancer Conundrum: Too Many Drug Trials, Too Few Patients. Another piece of the puzzle is clinical trial design, which can be especially elaborate when testing combination treatments in IO. Exacerbating these issues, IO trials are an increasingly competitive race to market. There is great value assigned to reducing development times and being the first drug approved within a class or for a specific indication.

This blog article discusses the current state of immuno-oncology studies, strategies for enhancing patient recruitment, the role of companion diagnostics and solutions for dealing with the complexity of IO combination studies. Continue reading

Can We Expand Companion Diagnostics Beyond Oncology?

The majority of today’s approved companion (and complementary) diagnostics (CDx) support personalized medicine efforts in oncology, a testament to researchers’ growing knowledge regarding the genetic pathways impacted in various cancers. That understanding increases our ability to convert such knowledge of biology into treatments that specifically target disease based on a tumor’s genetic makeup. This has led to significantly improved outcomes for many patients.

But can we leverage the knowledge of the biology of other disease states along with the appropriate technical progress into successful CDx expansion beyond oncology? Given that nearly 50% of all compounds in clinical development are dropped for lack of efficacy, CDx may represent a viable approach to improve this statistic and boost the efficiency of drug development efforts. Promising clinical areas where CDx may play an important role include immunology, rare and orphan diseases, and neurodegenerative diseases such as Alzheimer’s disease. Continue reading

Investing in the Future of Precision Medicine

In previous posts on this blog, our scientists have described the current state of precision medicine, particularly how it relates to companion diagnostics (CDx) and immuno-oncology. As an enterprise, we have been focused on this area of medicine essentially from the beginning, more than 20 years ago. LabCorp Diagnostics developed the clinical trials assay and served as the central lab for the testing of HER2-positive breast cancer during the development of trastuzumab. The company provided analytical testing data for the associated immunohistochemistry laboratory test resulting in the first companion diagnostic approved by the FDA. More recently, Covance was instrumental in supporting the drug development efforts for pembrolizumab, the therapy used successfully to treat former President Jimmy Carter’s melanoma, and its associated companion diagnostic.

Choosing the Best Pathway for CDx Development and Commercialization

Drug developers are increasingly incorporating a CDx development (companion diagnostic) strategy into their programs to deliver safer, more effective and appropriate therapies to the right patients. While the end result can be significantly beneficial forCovance Labs CDx Drug Development and Commercialization patients, and development partners, the path from analytical and clinical validation to demonstrating clinical utility and obtaining regulatory approval is often challenging. It requires a comprehensive understanding of clinical trial design, regulatory submission strategies both for the therapy and the diagnostic assay, and also a line of sight for successful commercialization.
