Integrating Genomics into Drug Discovery and Development: Challenges and Aspirations

摘要

Molecular biomarkers are increasingly being used to identify subgroups of patients that have a higher chance of benefiting from targeted therapies. Identification of predictive biomarkers and development of companion diagnostics to accompany targeted agents have been shown to significantly improve the efficacy and approval rate of these novel therapies, making treatment decisions more personalized to individual patients. Mutations of epidermal growth factor receptor (EGFR) and rearrangements of anaplastic lymphoma kinase (ALK) in non-small-cell lung cancer and of BRAF in melanoma provide great examples of driver mutations defining patient subgroups that respond to specific therapeutic agents. Recent advances in genomic technologies such as next-generation sequencing offer new opportunities for discovery and development of targeted therapies.
