CAMBRIDGE, Mass., Nov. 07, 2022 (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 third quarter ended September 30, 2022.
“The year 2022 has already been an incredibly productive period for Mersana as we have advanced UpRi, expanded our clinical pipeline and strengthened our balance sheet with two notable partnerships,” said Anna Protopapas, President and Chief Executive Officer of Mersana Therapeutics. “With significant support from global investigators, we were able to enroll approximately 270 patients in UPLIFT within just one year, positioning us for a planned top-line data readout and potential BLA submission next year. We also initiated UP-NEXT, our randomized Phase 3 clinical trial that has the potential to be our post-approval confirmatory trial in the United States, support approvals in other countries and bring UpRi into an earlier disease setting. Additionally, we view our recent collaborations as a reflection of the progress we have made in advancing our three innovative platforms and our position as a partner of choice within the ADC field. We believe these accomplishments strengthen our foundation and will enable us to enter 2023 with momentum.”
