(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 fourth quarter and full year ended December 31, 2023. "Mersana's unwavering commitment to payload and platform innovation has enabled us to enter 2024 with differentiated clinical-stage ADC product candidates, a strong balance sheet and forward momentum," said Martin Huber, M.D., President and Chief Executive Officer of Mersana Therapeutics. "We have made progress in the dose escalation portion of our Phase 1 clinical trial of XMT-1660 while also enrolling patients in backfill cohorts at multiple clinically relevant dose levels, setting the stage for our planned initial clinical data disclosure for this candidate in mid-2024. Over the course of this year, we also look forward to advancing dose escalation in our Phase 1 clinical trial of XMT-2056 as well as our collaborations with Johnson & Johnson and Merck KGaA." Mersana's Strategic Priorities and Expected Milestones XMT-1660: Mersana continues to advance its Phase 1 clinical trial of XMT-1660, the company's lead Dolasynthen ADC candidate targeting B7-H4. The dose escalation portion of the trial is ongoing, with the company having recently escalated to a dose of 59 milligrams per meter squared. A maximum tolerated dose has not yet been established. In addition to continuing to escalate dosing, the company also is enrolling patients in backfill cohorts to optimize dose and schedule. Mersana plans to initiate tumor-specific expansion cohorts in the second quarter of 2024 and expects to share initial dose escalation and backfill cohort data in mid-2024. XMT-2056: Mersana is restarting its Phase 1 clinical trial of XMT-2056, the company's lead Immunosynthen ADC candidate targeting a novel HER2 epitope. In the fourth quarter, the company announced the lifting of a clinical hold on the Phase 1 clinical trial of XMT-2056 by the U.S. Food and Drug Administration. Mersana plans to advance dose escalation of this wholly owned product candidate in 2024. GSK plc has an exclusive global license option to co-develop and commercialize XMT-2056. Collaborations: Mersana continues to advance its Johnson & Johnson (formerly known as Janssen) and Merck KGaA, Darmstadt, Germany collaborations. The Johnson & Johnson collaboration and license agreement focuses on the discovery of novel Dolasynthen ADCs for up to three targets. The Merck KGaA, Darmstadt, Germany collaboration and license agreement focuses on the discovery of novel Immunosynthen ADCs for up to two targets. Additional Upcoming Data Presentations: At the European Society of Gynaecological Oncology (ESGO) 2024 Congress from March 7-10, 2024 in Barcelona, Spain, clinical data will be presented for Mersana's two discontinued NaPi2b ADC product candidates: XMT-1536 (UpRi), which was developed using the company's first-generation Dolaflexin ADC platform, and XMT-1592, which was developed using the company's next-generation Dolasynthen ADC platform. Fourth Quarter 2023 Financial Results Cash, cash equivalents and marketable securities as of December 31, 2023 were $209.1 million.

Included in the fourth quarter of 2023 G&A expenses were $1.9 million in non-cash stock-based compensation expenses.

Included in 2023 R&D expenses were $11.0 million in non-cash stock-based compensation expenses.

Included in 2023 G&A expenses were $10.1 million in non-cash stock-based compensation expenses.
