**Exhibit 99.1**

**Werewolf Therapeutics Reports Third Quarter 2025 Financial Results and Provides Business Update**

*– Update on WTX-124 Phase 1/1b clinical trial interim data and End of Phase 1 meeting with the U.S. Food & Drug Administration (FDA) is expected to be provided later in the fourth quarter of 2025 –* 

*– Update on Phase 1b/2 clinical trial of WTX-330 and potential further development plan is expected to be provided later in the fourth quarter of 2025 –* 

*– WTX-1011, Company's first INDUCER*<sup>TM</sup> *T-cell engager development candidate targeting STEAP1, continues IND-enabling studies –* 

**Watertown, Mass., November 4, 2025 (GLOBE NEWSWIRE)** – Werewolf Therapeutics, Inc. (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 third quarter ended September 30, 2025.

"Werewolf is delivering on the promise of its proprietary PREDATOR® platform of conditionally activated immune therapeutics, marked by significant progress for our lead INDUKINETM clinical programs, WTX-124 and WTX-330, and our first INDUCER T-cell engager candidate, WTX-1011," said Daniel J. Hicklin, Ph.D., President and Chief Executive Officer of Werewolf. "For WTX-124, which received Fast Track Designation last month, we plan to provide an update later in the fourth quarter of 2025 on the path to a registration-enabling trial based on interim Phase 1/1b clinical trial data and feedback from an End of Phase 1 meeting with the FDA. At the same time, we plan to provide an update on the current Phase 1b/2 clinical trial of WTX-330 and a potential development plan for this program. Finally, we continue to make progress in IND-enabling studies for WTX-1011, our first INDUCER T cell Engager development candidate, and plan to nominate a differentiated target candidate by year-end."

**Recent Highlights and Upcoming Milestones**

**Clinical-Stage INDUKINE Molecules:** 

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• 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.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***◦*** Fast Track Designation received from the US FDA for the use of WTX-124 for the potential treatment of patients with locally advanced or metastatic cutaneous melanoma after standard of care immunotherapy. Fast Track Designation is intended to expedite the development of drugs to address a serious unmet medical need and provide opportunities for frequent FDA interactions.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***◦*** All expansion arms are either actively enrolling patients or fully enrolled in the ongoing Phase 1/1b clinical trial at a recommended dose of 18 mg administered intravenously every two weeks (IV Q2W). Enrollment is expected to be completed in all arms by the first quarter of 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***◦*** In the fourth quarter of 2025, Werewolf plans to release interim data from the monotherapy and combination expansion arms and to provide feedback from the Company's End of Phase 1 meeting with the FDA. These inputs are expected to provide insight into potential registrational pathways for WTX-124 in advanced or metastatic cutaneous melanoma.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***◦*** At the 2025 Society for Immunotherapy of Cancer's (SITC) 40th Annual Meeting, the Company will present a poster entitled: "Pharmacokinetic insight into the IL-2 INDUKINE prodrug WTX-124: real-time assessment of tumor-specific activation and immune modulation."

![werewolflogohorizontala.jpg](werewolflogohorizontala.jpg)

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• WTX-330:** *a systemically delivered, conditionally activated Interleukin-12 (IL-12) INDUKINE molecule being developed in advanced or metastatic solid tumors.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***◦*** Actively enrolling in a Phase 1b/2 clinical trial (WTX-330x2102) in locally advanced or metastatic solid tumors. An update on the clinical trial is expected to be released in the fourth quarter of 2025, with guidance on potential further development plans.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***◦*** At the 2025 Society for Immunotherapy of Cancer's (SITC) 40th Annual Meeting, the Company will present a poster entitled: "Sequential administration of WTX-124 and mWTX-330, IL-2 and IL-12 INDUKINE molecules, enhanced anti-tumor activity in mice bearing poorly immunogenic EMT6 tumors without systemic toxicity."

**Preclinical-Stage INDUCER Molecules:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•* WTX-1011:** *a potential first-in-class conditionally activated anti-STEAP1 T-cell engager to provide an improved therapeutic index.*

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**◦** STEAP1 is a promising prostate cancer target with limited expression in normal tissues, but notable toxicities are associated with existing anti-STEAP1 T-cell engager therapy.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**◦** Preclinical data demonstrated that PREDATOR<sup>®</sup> masking technology successfully silenced peripheral activity and prevented cytokine release.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** Utilizing a novel and highly effective anti-CD3 masking strategy, Werewolf expects to nominate a differentiated target candidate in the fourth quarter of 2025.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•*** At the 2025 Society for Immunotherapy of Cancer's (SITC) 40th Annual Meeting, the Company will present a poster entitled: "Development of conditional T cell engagers (INDUCER<sup>TM</sup> molecules) with a highly effective masking approach to reduce dose-limiting cytokine release and off-target peripheral toxicity."

**Preclinical-Stage INDUKINE Partnering Opportunities:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**•** Werewolf's previously announced development candidates available for partnering include: WTX-712, its Interleukin-21 (IL-21) INDUKINE molecule, and WTX-518, its binding protein resistant Interleukin-18 (IL-18) INDUKINE molecule, each 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.

**Financial Results for the Third Quarter of 2025:**

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;***•* Cash position:** As of September 30, 2025, cash and cash equivalents were $65.7 million, compared to $77.6 million as of June 30, 2025. The Company believes its cash and cash equivalents as of September 30, 2025, will be sufficient to fund operational expenses and capital expenditure requirements into the fourth quarter of 2026.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Research and development expenses:** Research and development expenses were $11.6 million for the third quarter of 2025, compared to $12.5 million for the same period in 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• General and administrative expenses:** General and administrative expenses were $4.1 million for the third quarter of 2025, compared to $4.6 million for the same period in 2024.

&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;&nbsp;**• Net loss:** Net loss was $16.4 million for the third quarter of 2025, compared to $16.7 million for the same period in 2024.
