Company Overview
Mersana Therapeutics is a clinical-stage biopharmaceutical company focused on developing novel antibody-drug conjugates (ADCs). The company's headquarters are located at 840 Memorial Drive, Cambridge, MA 02139. Mersana leverages its proprietary ADC platforms, Dolasynthen and Immunosynthen, to innovate cancer therapies and address the limitations of first-generation ADCs.
Proprietary ADC Platforms
Mersana Therapeutics has developed two proprietary ADC platforms: Dolasynthen and Immunosynthen. The Dolasynthen platform generates site-specific, homogeneous ADCs with precise control over the drug-to-antibody ratio (DAR), which can range from 2 to over 18. This allows for optimization of hydrophilicity, charge balance, linker stability, and DAR. The Immunosynthen platform, on the other hand, generates ADCs that systemically activate STING signaling in both tumor-resident immune cells and antigen-expressing cells, aiming to improve efficacy, delivery, and tolerability in cancer treatment.
Pipeline and Designations
Mersana's pipeline includes several advanced ADCs targeting cancers with high unmet medical needs. Notable candidates include XMT-1660 and XMT-2056. XMT-1660, a B7-H4-directed Dolasynthen ADC, has received Fast Track Designation from the U.S. Food and Drug Administration for treating adult patients with advanced or metastatic triple-negative breast cancer. XMT-2056, targeting a novel HER2 epitope, has been granted orphan drug designation by the U.S. Food and Drug Administration for the treatment of gastric cancer.
Collaborations and Strategic Partnerships
Mersana Therapeutics has established strategic collaborations with leading pharmaceutical and biotechnology companies such as Johnson & Johnson, GSK, and Merck KGaA, Darmstadt, Germany. These partnerships enhance Mersana's ability to develop and commercialize its ADC platforms and pipeline candidates, enabling broader reach and impact in oncology therapeutics.
Environmental and Social Governance (ESG) Initiatives
Mersana's ESG team is committed to promoting diversity, environmental sustainability, and community impact. The company's Green Team, founded in 2017, focuses on initiatives such as reducing office waste, cleaning local water sources, saving energy, and raising environmental awareness. Mersana operates with high integrity and transparency while actively supporting social responsibility projects.
