Werewolf Therapeutics Announces Initiation of Patient Dosing in Phase 1 Study of WTX-330
Werewolf Therapeutics has initiated a Phase 1 clinical trial for WTX-330, a novel Interleukin-12 (IL-12) therapy designed for the treatment of advanced solid tumors and Non-Hodgkin lymphoma. This trial marks the second INDUKINE molecule to enter clinical evaluation from their PREDATOR protein engineering platform. Dosing the first patient highlights Werewolf's commitment to advancing cancer therapies targeting hard-to-treat tumors. WTX-330 aims to minimize off-tumor toxicities while delivering potent treatment directly to the tumor microenvironment, potentially maximizing clinical benefits.
- First patient has been dosed in Phase 1 trial for WTX-330.
- WTX-330 is designed to minimize systemic toxicities typically associated with IL-12 therapies.
- Preclinical studies showed excellent anti-tumor activity and favorable pharmacokinetics for WTX-330.
- None.
WTX-330 is designed as systemically delivered, conditionally activated IL-12 therapy
Phase 1 Study of WTX-330 is intended to evaluate the safety, tolerability, and clinical activity of WTX-330 in Patients with Advanced or Metastatic Solid Tumors or Non-Hodgkin Lymphoma
Second clinical stage program of a new class of systemically delivered, conditionally activated INDUKINE™ therapeutics developed by Werewolf
WATERTOWN, Mass., Feb. 24, 2023 (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, today announced that the first patient has been dosed in a Phase 1 clinical trial evaluating WTX-330, the Company’s lead INDUKINETM molecule targeting Interleukin-12 (IL-12). The Phase 1 clinical trial is a first-in-human, multi-center, open-label trial that will evaluate WTX-330 in patients with advanced or metastatic solid tumors or lymphoma resistant to checkpoint inhibitors or for which checkpoint inhibitors are not approved.
“Dosing the first patient in our Phase 1 trial of WTX-330 marks the second INDUKINE molecule arising from our PREDATORTM protein engineering platform to enter the clinic. Our continued transition into a clinical stage company comes at an exciting time for Werewolf following the initiation of a Phase 1/1b clinical study of WTX-124 last year,” said Daniel J. Hicklin, Ph.D., Werewolf’s Founder and Chief Executive Officer. “WTX-330 serves as another example of our team's capacity to expand our clinical pipeline and validates our novel approach of developing conditionally activated cytokines as cancer therapies to improve outcomes for patients with hard-to-treat tumors.”
“We are pleased to begin patient dosing in our Phase 1 clinical trial with WTX-330, a novel tumor-selective IL-12 therapy with the potential to address the shortcomings associated with recombinant IL-12, including toxicities resulting from off-tumor effects,” said Randi Isaacs, M.D., Chief Medical Officer of Werewolf Therapeutics. “WTX-330 has the potential to be the only systemic, conditionally active IL-12 therapy with normal tissue IL-12R receptor blockade to deliver the full potency of IL-12 directly to the tumor microenvironment. We are eager to advance this candidate through the clinic with the goal of delivering a new treatment option for people living with cancer.”
IL-12 has historically been an extremely attractive immuno-oncology mechanism, having the ability to regulate antitumor immunity through numerous innate and adaptive immune pathways, but to-date has been undruggable due to serious toxicities when administered systemically. WTX-330 is specifically designed to maximize clinical benefit and minimize the severe toxicities that have been observed with recombinant IL-12 therapy by including high affinity blockade of IL-12 – IL-12R interaction in systemic circulation and non-tumor tissues, half-life extension for optimal tumor exposure and proprietary tumor-selective protease activation.
In preclinical studies, WTX-330 exhibited excellent anti-tumor activity and a favorable pharmacokinetic and tolerability profile. WTX-330 was designed to mediate robust anti-tumor activity through stimulation of innate and adaptive antitumor immune responses, including dendritic cell maturation and cross-presentation, Th1 differentiation and amplification of antitumor T effector cell responses.

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. 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.
