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

Applying Preclinical Biomarkers to Identify Renal Injuries

Identification of new medicines for kidney disease remains an ongoing challenge in drug Male Kidney Image Covance Blogdevelopment. This challenge includes establishing new biochemical measurements (biomarkers) which can sensitively and accurately reflect the status of renal health and any associated changes in renal function. Sponsors are exploring many options to improve the application of biomarkers in preclinical use in order to better inform early phase safety studies and downstream clinical trials.

Katherine Landschulz, PhD, associate director of the translational biomarker solutions laboratory, and veterinarian pathologist Laura Boone, DVM, PhD, recently shared their experiences working on renal disease studies at Covance. They discussed their insights on how biomarkers are being used in preclinical studies to predict safety and advance translational medicine in drug development.

The Current Status of Clinical Biomarkers for Diabetic Kidney Disease Progression

Of the 422 million people in the world with type 1 and 2 diabetes, 20-30% will develop diabetic nephropathy, also called diabetic kidney disease (DKD) – the leading cause of renal failure in the western world1.

From the perspective of drug developers, testing new therapies to prevent, treat or reverse this serious complication relies on biomarkers for timely and accurate patient identification and efficacy or safety monitoring.

Jennifer Ennis, MD, medical director at LabCorp and D. Walt Chandler, PhD, executive director at LabCorp, recently shared their thoughts on today’s biomarkers to detect and monitor DKD.

ELISPOT Assay: A Powerful Tool in Vaccine Development and Immune Monitoring

Over the past several years, the scientific community has made tremendous progress in advancing our understanding of the immune system, from the basic functions of its various components to molecular pathways that operate within those components. With new, state-of-the-art tools and technologies, immunologists now have the ability to better understand the mechanisms of immune response to various antigens, thereby aiding them in the development of novel approaches to treat immune-system-related diseases and better design vaccines to combat infectious agents and cancer.

Currently, one of the most sensitive techniques available for the detection, measurement, and functional analysis of immune cells is the enzyme-linked immunospot (ELISPOT) assay. Covance uses the ELISPOT technique in applications such as evaluation of vaccine efficacy and immunogenicity of biological products.

Going Virtual: Evolving Real World Evidence Study Design for
Speed, Flexibility and Lower Cost

Using a traditional clinical-site recruitment approach is no longer the only option in observational research. With the increased adoption of electronic informed consent methods by the FDA, it is now feasible to conduct real world evidence (RWE) studies using a virtual model that eliminates entirely the need for clinical sites.

Join us to learn how to lower cost and improve the efficacy of current, site-based RWE studies as well as:

  • The implications of electronic informed consent by the FDA
  • What is required to conduct a prospective virtual RWE study
  • How to use electronic data for a retrospective virtual RWE study

Precision Medicine in Immuno-Oncology

The NIH defines precision medicine as “an emerging approach for disease treatment and prevention that takes into account individual variability in genes, environment, and lifestyle for each person1.” In cancer patients, we can rephrase the definition to “through detailed understanding of a cancer’s biology, providing the right drug, for the right patient, at the right time.” Covance CRO Labs Blog

In order to identify the correct drug, biomarkers are used to identify patients that can be treated with the appropriate therapy for their cancer. The FDA defines biomarkers as “a defined characteristic that is measured as an indicator of normal biological processes, pathogenic processes, or responses to an exposure or intervention, including therapeutic interventions2.” Great strides have been made in the discovery and validation of biomarkers in drug development.

Strategic Alliance with Global Specimen Solutions: Introducing Covance SpecimINSIGHT™

The complexity of clinical trials continues to rise. New biomarkers for safety and efficacy continue to emerge, and new types of information – such as genomic profiles – have become critical to submissions for drug approval. Against this dynamic backdrop the Global Specimen Solutions Logocentral challenge facing trial sponsors remains the same: the need to bring together diverse data sets, draw meaningful insights from them and act quickly to maximize return on investment.

What Are the Emerging Noninvasive Biomarkers in NASH?

Novel biomarkers represent a promising means to improve diagnosis of nonalcoholic steatohepatitis (NASH). Currently, a definitive diagnosis requires a liver biopsy, a surgical Covance NASH Liver Disease Blogprocedure with many limitations. There are a variety of biomarkers that can assess liver status, but they do not always distinguish between patients with NASH and those with other disorders. Advanced imaging techniques, while useful for evaluating some liver features, can be impractical and costly.

The ultimate goal is to find noninvasive biomarkers that clearly show if the patient has steatohepatitis or liver fibrosis associated with nonalcoholic fatty liver disease (NAFLD). Recent studies suggest that nuclear magnetic resonance (NMR) spectroscopy, microRNA tests and genotyping may prove to be useful tools. Incorporating additional biomarkers into clinical trials can give biopharmaceutical companies an early indication of whether a compound is efficacious — and provide the confidence to move forward to the next phase of clinical testing.

Chinese biopharmaceuticals are expanding development beyond generics to focus on producing more personalized medicine, novel therapies, biomarkers and companion diagnostics. Steven Anderson, PhD, chief scientific officer at Covance, recently discussed his thoughts on biomarkers and precision medicine in China’s drug development and translational medicine landscape.

An emerging focus on biomarkers

“Efficacy of a drug therapy can vary widely and adverse effects can be common, but these parameters are not easily predicted,” explained Anderson. “That’s why biomarker-based, targeted treatments can guide therapy decision-making and better identify those individuals most likely to benefit.”
