4/2/2013 9:57:43 AM

CAMBRIDGE, Mass., April 2, 2013 /PRNewswire/ -- Merrimack Pharmaceuticals, Inc. (NASDAQ: MACK) today announced that research data on five novel experimental cancer therapies (MM-398, MM-121, MM-111, MM-302, and MM-141) will be presented at the 2013 American Association for Cancer Research (AACR) Annual Meeting, April 6-10, 2013 in Washington, DC. Presentations will include preclinical data evaluating the potential of treatments to restore tumor drug sensitivity and delay resistance when used alone or in combination with other targeted treatments. Data will be shared in late-breaking sessions, mini-symposia and poster sessions.

"We are excited about the advancements and research to be presented regarding several of the therapies in Merrimack's robust oncology pipeline," said Ulrik Nielsen, PhD, Co-Founder and Chief Scientific Officer, Merrimack Pharmaceuticals. "The research explores the potential of our novel medicines to inhibit signaling to prevent tumor growth and improve responsiveness to treatments, as well as the potential of our investigational nanotherapeutics to deliver chemotherapy directly to diseased cells to enhance activity and improve safety. These therapies are being studied across multiple cancers such as head and neck, lung, breast, gastric, pancreatic and melanoma."
