Mersana Presents New Data on Investigational Cancer Antibody Drug Conjugate at American Association of Cancer Research Annual Meeting
Poster Presentations Detail Advances in Company’s Lead Oncology ADC Compound, XMT-1522
CAMBRIDGE, Mass., March 2, 2017 -- Mersana Therapeutics, Inc., a biotechnology company focused on discovering and developing a pipeline of antibody drug conjugates (ADCs) based on its Fleximer® platform technology, today announced that it will present data on its lead preclinical immunoconjugate, XMT-1522, at the American Association of Cancer Research (AACR) Annual Meeting 2017 in Washington, D.C. The two poster presentations will highlight results from ongoing non-clinical studies where the compound was evaluated as a potential combination partner with immunomodulatory cancer therapies and it was also characterized for its pharmacokinetics, metabolism and biodistribution in tumor-bearing mice.
The accepted abstracts are listed below and are now available online on the AACR 2017 conference website: www.aacr.org

About XMT-1522
XMT-1522 incorporates a novel, proprietary HER2 antibody, which is conjugated with Mersana’s Dolaflexin platform which includes its Fleximer technology and proprietary auristatin payload. XMT-1522 provides a drug load of approximately 12-15 molecules per antibody, specifically designed to improve potency while simultaneously increasing tolerability. XMT-1522 has the potential to extend HER2-targeted therapy beyond the current “HER2-positive” populations into patients with lower levels of HER2 expression.
About Mersana Therapeutics
Mersana Therapeutics is a biotechnology company with highly differentiated and proprietary immunoconjugate platforms that allow for significantly higher drug loads, providing greater efficacy while simultaneously increasing tolerability. As a result, our platforms provide for expanded opportunities to provide meaningful clinical benefit to patients. Our lead program, XMT1522, is in Phase I clinical trials. Our second program, XMT1536, will be entering clinical trials in the latter part of 2017. In addition, our partners are advancing their pipeline of immunoconjugates using our platforms.
