Pharmaceutical companies are increasingly relying on biomarkers to deliver precision medicine in immuno-oncology. Biomarkers can accelerate drug development and reduce the overall cost; they also allow sponsors to identify failed treatments sooner so that resources are not wasted on expensive, late-stage trials with unsafe or inactive compounds. Finally, these tests lead to better outcomes for patients, which help companies make a stronger case for reimbursement.
However, biomarker discovery requires substantial time and resources. While expenses will likely be outweighed by increased development efficiency, companies must ensure that drug and diagnostic timelines are closely aligned so that the treatment and test can launch simultaneously. Technical, workflow and commercial factors are critical to the successful use of immuno-oncology biomarkers. Continue reading
The rise of immunotherapy has been meteoric — there are now well more than 1,000 immuno-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
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.”
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.
