Merrimack is a fully integrated biopharmaceutical company that views cancer as a complex engineering challenge. Through systems biology, which brings together the fields of biology, computing and engineering, Merrimack aims to decrease uncertainty in drug development and clinical validation, and move discovery efforts beyond trial and error. Such an approach has the potential to make individualized treatment of patients a reality. Merrimack's first commercial product, ONIVYDETM (irinotecan liposome injection), was approved by the U.S. FDA and with four additional candidates in clinical studies, several in preclinical development and multiple biomarkers designed to support patient selection, the Company is building one of the most robust oncology pipelines in the industry.
