Watertown, Mass., May 3, 2024 – 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 first quarter ended March 31, 2024.
“Werewolf continues to focus on the execution of our lead clinical programs WTX-124 and WTX-330, with updates planned for later in the second quarter. At ASCO, we plan to share data from the dose-escalation portion of our Phase 1/1b trial evaluating WTX-124 as a single agent and in combination with pembrolizumab. In addition, we look forward to sharing interim, first-in-human monotherapy dose escalation data from the ongoing Phase 1/1b trial of WTX-330 in the second quarter.” said Daniel J. Hicklin, Ph.D., President and Chief Executive Officer of Werewolf. “We continue to execute on our pipeline of INDUKINE molecules in oncology and immunology and are now projecting our financial runway to run through at least the first quarter of 2026.”
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.
•At the American Society for Clinical Oncology (ASCO) Annual Meeting, the Company will present additional interim data from the monotherapy dose-escalation arm and preliminary dose-escalation data from the combination arm of its ongoing Phase 1/1b clinical trial of WTX-124. Details for the poster presentation are as follows:
◦Title: A phase 1/1b study of the IL-2 prodrug WTX-124 in patients with locally advanced or metastatic solid tumors after checkpoint inhibitor therapy: Initial results of the combination dose escalation with pembrolizumab
◦Session Date: Saturday, June 1, 2024
◦Session Time: 9:00 AM-12:00 PM CDT
•Werewolf remains on track to select a recommended dose for expansion and initiate monotherapy dose expansion arms in the first half of 2024.
WTX-330: a systemically delivered, conditionally activated Interleukin-12 (IL-12) INDUKINE molecule being developed in advanced or metastatic solid tumors.
•In the second quarter of 2024, Werewolf plans to present interim first-in-human data from Study WTX-330x2101, its Phase 1, multi-center, open-label clinical trial evaluating WTX-330 as a monotherapy in patients with immunotherapy insensitive or resistant advanced or metastatic solid tumors or non-Hodgkin lymphoma.
•Werewolf recently received U.S. Food and Drug Administration alignment on the comparability path for an improved manufacturing process which Werewolf expects to integrate into the clinical development program.
Preclinical Portfolio: includes development candidates WTX-712 and WTX-518, INDUKINE molecules targeting IL-21 and IL-18, respectively, for treatment of cancer and an INDUKINE molecule delivering IL-10 for treatment of Irritable Bowel Disease.
•During the American Association for Cancer Research Annual Meeting in April 2024, Werewolf presented two posters detailing progress of WTX-518 and WTX-712 preclinical programs, which the Company is progressing through investigational new drug application-enabling work:
◦WTX-518: Poster entitled “WTX-518, an IL-18 pro-drug that is conditionally activated within the tumor microenvironment and induces regressions in mouse tumor models,” demonstrated in vitro activity unimpeded by IL-18BP and selectivity that delivers active binding protein resistant (BPR) IL-18 to the tumor microenvironment, eliciting complete tumor regression in an MC38 mouse tumor model.
◦WTX-712: Poster entitled “WTX-712, a conditionally active IL-21 INDUKINETM molecule, induces a strong anti-tumor phenotype through a differentiated mechanism,” demonstrated antitumor activity and tumor regression in the MC38 mouse tumor model. IL-21 was observed to achieve superior anti-tumor efficacy compared to IL-2 therapy in mouse tumor models that are highly resistant to anti-PD-1/PD-L1 treatment.
•During the American Association of Immunologists Meeting which begins May 3, 2024, Werewolf is presenting a poster entitled “Development of conditionally active IL-10 INDUKINETM molecules for the treatment of inflammatory bowel disease.” These are the first data demonstrating application of the Company’s PREDATOR platform in immune-mediated disease, indicating that IL-10 INDUKINE molecules were peripherally inactive and conditionally active in target tissue thereby preventing intestinal histological damage and inhibiting inflammatory cytokine production in mouse models of colitis.
Additional Updates:
•In May 2024, Werewolf entered into a loan and security agreement with K2 HealthVentures, a healthcare focused specialty finance company, which provides Werewolf with access to up to $60.0 million in capital, $30.0 million of which was drawn at closing and, along with the Company’s existing cash, was used to repay the Company’s loan with Pacific Western Bank.
Financial Results for the First Quarter of 2024:
•Cash position: As of March 31, 2024, cash and cash equivalents were $139.2 million, compared to $134.3 million as of December 31, 2023. The Company also had restricted cash and cash equivalents of $21.2 million as of both March 31, 2024 and December 31, 2023, of which $20.0 million became unrestricted upon the repayment of the Pacific Western Bank loan. The Company believes its existing cash and cash equivalents at March 31, 2024, together with cash impacts of the loan refinancing, will be sufficient to fund operational expenses and capital expenditure requirements through at least the first quarter of 2026.
•Collaboration revenue: Collaboration revenue was $0.7 million for the first quarter of 2024, compared to $4.5 million for the same period in 2023. Collaboration revenue consists of revenue recognized from the Company’s licensing agreement with Jazz Pharmaceuticals (Jazz) and includes fixed payments received from Jazz, plus costs incurred for research services to be reimbursed by Jazz.
•Research and development expenses: Research and development expenses were $12.9 million for the first quarter of 2024, compared to $11.7 million for the same period in 2023. The increase in research and development expenses was primarily due to the Company’s development efforts for WTX-124 and WTX-330, which continue to progress through their respective clinical trials, resulting in higher clinical trial costs and higher manufacturing costs to support those trials.
•General and administrative expenses: General and administrative expenses were $5.0 million for each of the first quarters of 2024 and 2023.
•Net loss: Net loss was $16.2 million for the first quarter of 2024, compared to $12.0 million for the same period in 2023.
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. We are leveraging our 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. Our INDUKINE™ molecules are intended to remain inactive in peripheral tissue yet activate selectively in the tumor microenvironment. Our 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. We expect to advance 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.
