CAMBRIDGE, Mass., Jan. 06, 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 announced strategic objectives and expected milestones for 2023.
“Following a year of tremendous accomplishment in 2022, we are now approaching top-line data from our first registrational trial of UpRi, which we believe will provide an opportunity to further demonstrate Mersana’s increasing role as an ADC leader,” said Anna Protopapas, President and Chief Executive Officer of Mersana Therapeutics. “The data we expect to report from our UPLIFT clinical trial in mid-2023 will represent the most significant milestone to date in our effort to establish UpRi as a foundational medicine for patients with ovarian cancer. Assuming positive data, we plan to target the submission of a BLA around the end of 2023 and prepare for a potential U.S. commercial launch in 2024. We will also continue to advance our UP-NEXT and UPGRADE-A trials of UpRi in earlier lines of treatment.”
“Beyond UpRi, our efforts to expand the reach of all three of our fully-scaled ADC platforms, each supported by substantial data, will remain a central theme in 2023,” continued Ms. Protopapas. “We will work aggressively to progress our two next-generation ADCs, XMT-1660 and XMT-2056, in Phase 1 trials and establish proof-of concept. Additionally, exploring new collaborations will remain a core component of our strategy as we seek to build upon Mersana’s recent business development successes.”

• Announced that the European Commission has designated UpRi as an orphan medicinal product for the treatment of ovarian cancer
Expected Milestones
• Report top-line data from UPLIFT in mid-2023
• Assuming positive data, submit a biologics license application (BLA) to the U.S. Food and Drug Administration (FDA) around the end of 2023
• Prepare for potential U.S. accelerated approval and commercial launch in 2024
• Significantly advance enrollment of UP-NEXT in 2023

Financial Update
Mersana estimates that its cash, cash equivalents and marketable securities as of December 31, 2022 were approximately $280 million. This figure is preliminary and unaudited.
