"We made significant progress advancing the clinical development of Emi-Le in 2024," said Martin Huber, M.D., President and Chief Executive Officer of Mersana Therapeutics. "These efforts enabled us to begin 2025 by announcing positive initial Phase 1 clinical data, the initiation of expansion and a Fast Track designation for HER2-negative breast cancer patients who have previously been treated with at least one topo-1 ADC. With promising monotherapy activity reported in patients across multiple tumors, including those with heavily pretreated triple-negative breast cancer, as well as a differentiated tolerability profile that may enable combination approaches, we believe Emi-Le offers us unique development opportunities that are unavailable to other B7-H4 ADCs."

Emiltatug Ledadotin (Emi-Le; XMT-1660)
In January 2025, Mersana announced positive initial Phase 1 clinical data for Emi-Le, the company’s lead Dolasynthen ADC candidate targeting B7-H4, from 130 patients who were enrolled in dose escalation and backfill cohorts as of a December 13, 2024 data cutoff. The company also announced that Emi-Le had received a second Fast Track designation from the U.S. Food and Drug Administration (FDA).

The expansion portion of the company’s Phase 1 clinical trial continues at a dose of 67.4 mg/m² administered every four weeks in patients with TNBC who had received one to four prior lines of therapy, including at least one topo-1 ADC. In parallel, the company continues to explore higher doses in dose escalation and backfill cohorts to identify a second dose for expansion.

In 2025, Mersana plans to initiate expansion enrollment at a second dose in patients with TNBC who have received one to four prior lines of treatment, including at least one prior topo-1 ADC. The company also plans to present additional Phase 1 clinical data from dose escalation and backfill cohorts in 2025.

XMT-2056
Mersana has continued to advance the dose escalation portion of its Phase 1 clinical trial of XMT-2056, the company’s lead Immunosynthen ADC candidate targeting a novel HER2 epitope. GSK plc has an exclusive global license option to co-develop and commercialize XMT-2056. Mersana plans to continue enrolling patients in dose escalation and expects to present initial clinical pharmacodynamic STING activation data for XMT-2056 in 2025.

Collaborations
Mersana continues to advance its collaborations with both Johnson & Johnson (Dolasynthen research collaboration) and Merck KGaA, Darmstadt, Germany (Immunosynthen research collaboration).

The collaboration will integrate IDEAYA’s differentiated and proven capabilities in structural biology and pharmaceutical drug discovery across multiple first-in-class oncology targets with ATTMOS’s capabilities in computational chemistry method development, high performance computing, and software development. The focus of the partnership will be to engineer and optimize a workflow solution for high-throughput absolute binding free energy perturbation predictions (ABFEP) of first-in-class drug candidate molecules. This approach enables application of gold-standard physics-based statistical mechanics calculations of protein-ligand affinities at the scale required for virtual screens and represents what could become the industry’s go-to standard for high-speed and high probability-of-success drug hit-finding against structurally-enabled novel biological targets.

"Current AI/ML-enabled drug discovery approaches have been largely applied to either already drugged targets or well-understood biological target classes and often fail when applied to first-in-class target opportunities. IDEAYA continues to enhance its computational drug discovery capabilities to pursue first-in-class oncology targets that are perceived as undruggable," said Michael White, Ph.D., Chief Scientific Officer, IDEAYA Biosciences. "Our partnership with ATTMOS will enable us to apply the principles of engineering to the field of drug discovery, at scale, for efficient prosecution of unprecedented oncology targets," said Paul Barsanti, Ph.D., Chief Technology Officer, IDEAYA Biosciences.

The collaboration will leverage the Amber molecular dynamics suite as the GPU-accelerated back-end free energy simulation engine. IDEAYA will train and evaluate ABFEP-based active learning cycles based on extensive ground-truth data sets derived from its successful wet-lab drug discovery campaigns against novel targets. These models will be used to screen enormous libraries of synthetically tractable chemical space for accurate and efficient de novo discovery of small molecule ligands for new targets. The work aims to overcome the limitations of current virtual screening approaches and accelerate the discovery of novel small molecule oncology therapeutics that address unmet clinical need.

Fourth Quarter and Recent Highlights
Bexotegrast Highlights
•BEACON-IPF discontinued following recommendation from expanded data safety monitoring board (DSMB). Following a prespecified data review and recommendation by the trial’s independent DSMB, as well as a secondary review and recommendation by an outside expert panel, Pliant has discontinued the BEACON-IPF Phase 2b trial. While an imbalance in unadjudicated IPF-related adverse events between the treatment and placebo groups led to the discontinuation of the trial, early evidence of efficacy on the forced vital capacity (FVC) endpoint was also observed. The Company plans to analyze the complete data from the BEACON-IPF trial and evaluate next steps for bexotegrast’s development. BEACON-IPF is a 52-week, multinational, randomized, dose-ranging, double-blind, placebo-controlled trial evaluating bexotegrast at once-daily doses of 160 mg or 320 mg in patients with idiopathic pulmonary fibrosis (IPF).

Oncology Program
•Phase 1 trial of PLN-101095 in solid tumors continues to enroll, with interim data expected in the first quarter 2025. This is a Phase 1 open label trial of PLN-101095, an oral, small molecule, dual selective inhibitor of αvβ8 and αvβ1 integrins designed to block TGF-β activation in the tumor microenvironment. The trial is currently dosing the fourth of five planned dose cohorts in a Phase 1 open label dose-escalation trial of PLN-101095 as monotherapy and in combination with pembrolizumab in patients with solid tumors that are resistant to immune checkpoint inhibitors. Interim data from the first three cohorts is expected in the first quarter of 2025.

Neuromuscular Program
•PLN-101325 for treatment of muscular dystrophies. PLN-101325 is a monoclonal antibody that acts as an allosteric agonist of integrin α7β1, currently in development for treatment of muscular dystrophies. PLN-101325 is Phase 1 ready with clinical trial approval (CTA) open in Australia.

Corporate Highlights
•Appointment of Delphine Imbert, Ph.D. as Chief Technical Officer. Dr. Imbert brings 25 years of product development, process optimization and manufacturing experience across multiple drug modalities. Most recently, Dr. Imbert served as Senior Vice President of CMC and Technical Operations at Chinook Therapeutics.

Fourth Quarter 2024 Financial Results
•Research and development expenses were $38.8 million, as compared to $33.2 million for the prior-year quarter. The increase was primarily due to costs associated with the BEACON-IPF Phase 2b/3 clinical trial.
•General and administrative expenses were $14.5 million, as compared to $13.9 million for the prior-year quarter. The increase was primarily due to employee-related expenses driven by increased headcount over prior year.

•Net loss was $49.7 million as compared to $41.1 million for the prior-year quarter. The increase was due to higher operating expenses primarily attributable to costs associated with the BEACON-IPF Phase 2b/3 clinical trial and reduced interest income on short-term investments.
•As of December 31, 2024, the Company had cash, cash equivalents, restricted cash and short-term investments of $357.2 million which the Company expects to be sufficient to fund operations for the next 12 months and beyond.
