The term biomarker signature describes the behavior of a set of biomarkers that define a signature to maximize the prediction performance. How we apply a biomarker signature depends on the prediction problem. A prognostic biomarker signature is used to predict the disease progression, a risk biomarker signature is used to identify sets of subjects that are likely to develop a disease, and a predictive biomarker signature is used to determine the patients that are likely to respond to a particular treatment.
In this case study, a client was developing a new drug for complex neurodegenerative disease in pre-clinical development. The drug may be only effective for a particular subgroup of patients. They needed to generate a hypothesis on the molecular pathway and the targeted drug activity and identify a biomarker signature defining potential response to the new drug. Read how Cytel’s analysis produced a biomarker signature that was provided to the client for in-vivo validation.
