CAMBRIDGE, Mass., Aug. 08, 2023 (GLOBE NEWSWIRE) -- Mersana Therapeutics, Inc. (NASDAQ: MRSN), a clinical-stage biopharmaceutical company focused on discovering and developing a pipeline of antibody-drug conjugates (ADCs) targeting cancers in areas of high unmet medical need, today provided a business update and reported financial results for the second quarter ended June 30, 2023.
“Mersana has focused heavily on the development of new product candidates and business development opportunities that leverage our innovative next-generation ADC platforms,” said Anna Protopapas, President and Chief Executive Officer of Mersana Therapeutics. “These efforts have yielded promising new programs based on our Dolasynthen and Immunosynthen platforms that have the potential to benefit a wide range of patients who are waiting for new treatment options. Given the strength of our balance sheet, pipeline and collaborations, we are very excited about the opportunities ahead for Mersana.”
Mersana’s Strategic Priorities
Advance XMT-1660 and Dolasynthen Platform: Dolasynthen is Mersana’s next-generation cytotoxic ADC platform that is designed to generate site-specific, homogeneous ADCs, utilizes a proprietary auristatin payload and has the ability to match the drug-to-antibody ratio to specific targets. The company is advancing the development of XMT-1660, a B7-H4-directed Dolasynthen ADC with a precise, target-optimized drug-to-antibody ratio (DAR 6). Mersana expects to complete the dose escalation portion of its Phase 1 clinical trial of this candidate in 2023 and initiate the dose expansion portion of the trial in 2024. Additionally, Mersana is supporting Janssen Biotech under a collaboration and license agreement that focuses on discovering novel Dolasynthen ADCs for up to three targets.
Advance XMT-2056 and Immunosynthen Platform: Immunosynthen is Mersana’s proprietary STING agonist platform that is designed to generate systemically administered ADCs that locally activate STING signaling in both tumor-resident immune cells and in antigen-expressing cells to unlock the anti-tumor potential of innate immune stimulation. Mersana is working diligently to address the clinical hold on its Phase 1 clinical trial of XMT-2056, its lead Immunosynthen ADC candidate, which targets a novel HER2 epitope. GSK plc has an exclusive option to co-develop and commercialize XMT-2056. Additionally, Mersana is supporting Merck KGaA, Darmstadt, Germany under a collaboration and license agreement that focuses on discovering novel Immunosynthen ADCs for up to two targets.
