- Data Show Fleximer(R) Extends Exposure to Conjugated Drug -
CAMBRIDGE, Mass., April 19 /PRNewswire/ -- Mersana, a platform-based cancer therapeutics company, today announced positive results of preclinical studies for its second development candidate, XMT-1107, in two posters at the 2009 Annual Meeting of the American Association of Cancer Research (AACR) in Denver.
The studies showed that XMT-1107, a novel anti-angiogenic fumagillin analog conjugated to Mersana's proprietary Fleximer(R), demonstrated superior anti-tumor activity in tumor xenograft models in comparison to other anti-angiogenic agents and extended exposure to the conjugated drug, supporting the potential clinical utility of XMT-1107 as an anti-cancer agent. Full text of the abstracts can be viewed online at the AACR website at www.AACR.org.
"We're encouraged by the ongoing progress we're seeing with XMT-1107, which targets a novel mechanism to inhibit endothelial cell proliferation and has the potential to target a wide variety of angiogenic tumors," said Julie Olson, Mersana CEO. "Earlier drugs in this class showed promising activity in the clinic but were discontinued due to reversible neurological toxicity. Conjugation of our novel fumagillin 'warhead' to Fleximer using a specific linker technology reduces CNS exposure in animal models to below detection limits. We look forward to advancing XMT-1107 into clinical studies by early 2010."

This study showed that XMT-1107 has enhanced anti-angiogenic and anti-tumor activity compared to small molecule analogs delivered without the benefit of Fleximer.
