CAMBRIDGE, Mass., March 23, 2017 /PRNewswire/ -- Merrimack Pharmaceuticals, Inc. (NASDAQ: MACK) today announced the enrollmentof its first patient in a Phase 1 study of MM-310 in solid tumors. MM-310 is an antibody-directed nanotherapeutic (ADN) that encapsulates a novel taxane and targets the EphA2 receptor, a protein which surveys suggest is overexpressed in 50-100% of many
"The initiation of this study is an important step in evaluating MM-310's safety and preliminary activity in patients diagnosed with solid tumors," said Vasileios Askoxylakis, MD, PhD, Medical Director and MM-310 Project Leader at Merrimack. "MM-310 was designed to maximize targeted delivery and local activation of a newly engineered and proprietary prodrug of docetaxel, a broadly-used potent chemotherapy that is often associated with significant drug-related toxicities, with a goal of minimizing exposure to healthy tissue. In several preclinical models, MM-310 not only demonstrated superior antitumor activity when compared to free docetaxel, but also fewer hematologic toxicities. We look forward to continuing MM-310's development via this study."
The Phase 1 open-label study will assess the safety, pharmacology and preliminary activity of MM-310 in three parts. In part one, MM-310 will be assessed as a monotherapy until a maximum tolerated dose (MTD) is established. After the MTD of MM-310 is established, the study will include two further concurrent parts consisting of an expansion cohort as a single agent and a dose-finding phase in combination with other therapies. Merrimack expects to report data from part one of the study in 2018.
Five sites are currently expected to participate in this study. The first patient was dosed at Honor Health in Scottsdale, AZ.
MM-310 is an antibody-directed nanotherapeutic (ADN) that encapsulates a novel prodrug of the highly potent chemotherapy docetaxel in an ephrin receptor A2 (EphA2)-targeted liposome. EphA2 receptors are shown to be overexpressed in several solid tumors, including prostate, ovarian, bladder, gastric, pancreatic and lung cancers. Moreover, EphA2 receptors are associated with poor outcomes in certain indications. Preclinical data on MM-310 were presented in an oral presentation and three poster sessions at the 2016 American Association for Cancer Research (AACR) Annual Meeting and further data will be presented at the 2017 AACR Annual Meeting in April.
