(the “Company” or “Werewolf”) (Nasdaq: HOWL), an innovative biopharmaceutical company pioneering the development of conditionally activated therapeutics engineered to stimulate the body’s immune system for the treatment of cancer and other immune-mediated conditions, today provided a business update and reported financial results for the first quarter ended March 31, 2025. “Werewolf continues to build on our promising data and progress across our clinical-stage programs,” said Daniel J. Hicklin, Ph.D., President and Chief Executive Officer of Werewolf. “We remain on track in our Phase 1/1b clinical trial evaluating WTX-124 to share interim data and meet with the FDA to discuss potential registrational pathways in the second half of this year. Additionally, in recognition of Skin Cancer Awareness month, Werewolf is launching an educational campaign in May to highlight the differentiation of Werewolf’s conditionally activated therapeutics and patient experiences to date in the WTX-124 clinical trial. I am also pleased to report that we recently initiated a Phase 1b/2 clinical trial of WTX-330 to explore antitumor activity and optimize the exposure of our IL-12 INDUKINE molecule in the tumor microenvironment. Finally, Werewolf has been making significant progress towards nominating its first INDUCER T cell engager development candidate in the second quarter of 2025, with preclinical data demonstrating that PREDATOR® masking technology successfully silenced peripheral activity and prevented cytokine release. We believe that our proprietary PREDATOR masking and targeting technology distinctly positions us to build a robust pipeline of T cell engagers with potentially best-in-class potency and safety profiles, filling a gap in the current immuno-oncology landscape.” Recent Highlights and Upcoming Milestones WTX-124: a systemically delivered, conditionally activated Interleukin-2 (IL-2) INDUKINE molecule being developed as monotherapy and in combination with pembrolizumab in multiple solid tumor types. All expansion arms are actively enrolling patients in the ongoing Phase 1/1b clinical trial at a recommended dose of 18 mg administered intravenously every two weeks (IV Q2W).During the second half of 2025, Werewolf plans to present interim data from the monotherapy and combination expansion arms, including tolerability, response rate, and durability, and to engage with regulatory authorities to discuss potential registrational pathways for WTX-124, including strategies for accelerated approval.The data continue to demonstrate clinically meaningful anti-tumor activity with a tolerable safety profile in patients who have previously been treated with immune checkpoint inhibitors.Launching a skin cancer awareness campaign educating various stakeholders on WTX-124 patient outcomes to date and the innovative science underlying Werewolf’s IL-2 cytokine therapy. WTX-330: a systemically delivered, conditionally activated Interleukin-12 (IL-12) INDUKINE molecule being developed in advanced or metastatic solid tumors. Initiated patient dosing in a Phase 1b/2 clinical trial (WTX-330x2102) to optimize the exposure of WTX-330 in the tumor microenvironment, following the encouraging clinical activity and tolerability seen in the WTX-330x2101 first-in-human study. Preclinical Portfolio: Werewolf’s previously announced development candidates WTX-712, its Interleukin-21 (IL-21) INDUKINE molecule, and WTX-518, its binding protein resistant Interleukin-18 (IL-18) INDUKINE molecule, for the treatment of cancer, and WTX-921, a first-of-its-kind Interleukin-10 (IL-10) INDUKINE molecule for the treatment of inflammatory bowel disease (IBD) and potentially other inflammatory diseases, are available for partnering.Werewolf has extended its conditional activation technology to T cell engagers, utilizing a novel and highly effective anti-CD3 masking strategy for its INDUCER T cell engager molecules. Preclinical data demonstrate that the Company’s PREDATOR masking technology successfully silenced peripheral activity and prevented cytokine release in its INDUCER molecules. The Company’s first INDUCER development candidate is expected to be nominated in the second quarter of 2025. Financial Results for the First Quarter of 2025: Cash position: As of March 31, 2025, cash and cash equivalents were $92.0 million, compared to $111.0 million as of December 31, 2024. Based on updated forecasting, the Company now believes its existing cash and cash equivalents as of March 31, 2025, will be sufficient to fund operational expenses and capital expenditure requirements into the fourth quarter of 2026.Research and development expenses: Research and development expenses were $13.1 million for the first quarter of 2025, compared to $12.9 million for the same period in 2024.General and administrative expenses: General and administrative expenses were $4.9 million for the first quarter of 2025, compared to $5.0 million for the same period in 2024.Net loss: Net loss was $18.1 million for the first quarter of 2025, compared to $16.2 million for the same period in 2024. About Werewolf Therapeutics:Werewolf Therapeutics, Inc., is an innovative biopharmaceutical company pioneering the development of therapeutics engineered to stimulate the body’s immune system for the treatment of cancer and other immune-mediated conditions. The Company is leveraging its proprietary PREDATOR® platform to design conditionally activated molecules that stimulate both adaptive and innate immunity with the goal of addressing the limitations of conventional proinflammatory immune therapies. Werewolf’s INDUKINE molecules are intended to remain inactive in peripheral tissue yet activate selectively in the tumor microenvironment. The Company’s most advanced clinical stage product candidates, WTX-124 and WTX-330, are systemically delivered, conditionally activated Interleukin-2 (IL-2) and Interleukin-12 (IL-12) INDUKINE molecules, respectively, for the treatment of solid tumors. Werewolf is advancing WTX-124 in multiple tumor types as a single agent and in combination with an immune checkpoint inhibitor and WTX-330 in multiple tumor types or Non-Hodgkin Lymphoma as a single agent.
