Werewolf Therapeutics Highlights Initial Safety and Efficacy Data from its Ongoing Phase 1 Clinical Trial Evaluating WTX-330 in Patients with Advanced or Metastatic Solid Tumors or Non-Hodgkin Lymphoma

Werewolf Therapeutics, Inc. announced initial results from the Phase 1 clinical trial evaluating WTX-330, its conditionally activated interleukin-12 (IL-12) INDUKINE™ molecule, as monotherapy in patients with immunotherapy insensitive or resistant locally advanced or metastatic solid tumors or non-Hodgkin lymphoma. IL-12 therapy holds tremendous promise for immune-resistant cancer patients but has been historically limited by severe toxicity, like many cytokines. Werewolf is developing a novel, conditionally activated IL-12, WTX-330, in order to overcome this key limitation with its systemically administered, tissue-targeted technology, optimizing its therapeutic index so that efficacious doses can be delivered for clinical impact. As of the cutoff date of June 12, 2024, the study had dosed eleven patients in dose escalation with solid tumors relapsed or refractory to all standard of care therapies with at least one dose of WTX-330 across three dose escalation cohorts, 0.016 mg/kg (n=3), 0.024 mg/kg (n=3), or 0.032 mg/kg (n=5) and two patients in dose expansion at 0.024 mg/kg. Preliminary results as of the cutoff date showed: Greatly increased therapeutic window: Compared to previous IL-12 therapeutic strategies (recombinant human IL-12 (rhIL-12) at 500 ng/kg (maximum tolerated dose)), at the 0.024 mg/kg dose, WTX-330 demonstrated an approximately 23-fold higher systemic drug concentration of IL-12 prodrug delivered to patients in the outpatient setting, with low free IL-12 levels across all dose levels (<1.6% of prodrug exposure). Encouraging signals of clinical activity: One patient with metastatic melanoma who had previously progressed on adjuvant pembrolizumab was treated with 0.024 mg/kg WTX-330 administered intravenously once every two weeks (IV Q2W) and achieved an unconfirmed partial response by Response Evaluation Criteria in Solid Tumors (RECIST) after eight weeks with no evidence of disease on biopsy and marked decreased uptake on positron emission tomography (PET) imaging. A confirmatory scan for this patient is pending. Two additional patients with microsatellite stable (MSS) colorectal cancer (CRC) were treated with 0.032 mg/kg WTX-330 IV Q2W and achieved RECIST stable disease, one for 24 weeks with evidence of tumor biomarker activity. Robust activation of immune biomarkers: Evidence of increased antitumor CD8+ T and natural killer (NK) cell expansion and activation in on-treatment tumor biopsies and/or upregulation of tumor immune gene signatures were observed in the two MSS CRC patients with stable disease. Emerging tolerability profile: All patients exhibited mild to moderate treatment-related toxicities (fever, chills, cytopenias) primarily associated with the first dose, with no Grade 4 or Grade 5 related adverse events. These were correlated with dose-dependent increases in peripheral IFN? and IP-10. Two patients experienced reversible dose-limiting toxicities (Grade 3 mucositis, Grade 3 aspartate aminotransferase (AST) increase) at the 0.032 mg/kg dose level, including the MSS CRC patient with prolonged stable disease who remained on therapy for over 6 months after resolution of the mucositis. A maximum tolerated dose has not been established. Expanded Phase 1 program: The Company has opened two expansion arms evaluating 0.024 mg/kg of WTX-330. Eligible patients include those with immune checkpoint inhibitor (ICI)-sensitive solid tumors who demonstrate primary or secondary resistance to immunotherapy (Arm A) and patients with solid tumors or lymphoma for whom ICI blockade is not approved or indicated (Arm B). Two patients have been enrolled into the expansion arms to date and have received at least one dose of WTX-330. Interleukin-12 (IL-12) is a cytokine well recognized as a promising antitumoral therapeutic agent due to its range of functions that include activation of natural killer (NK) cells, NK T and CD8+ T cells, promotion of dendritic cell (DC) antigen presentation, and production of IFN-?. Native IL-12 is highly toxic, and all previous methods of administration of the molecule at potentially efficacious doses have resulted in unmanageable systemic toxicities or lack of efficacy. To leverage the potent therapeutic properties of IL-12, there is a need to develop locally active but systemically blocked IL-12-based treatment approaches. WTX-330 was designed to be a systemically dosed prodrug with the ability to deliver fully active IL-12 selectively into the tumor microenvironment via targeted intratumoral activation of the INDUKINE molecule, potentially broadening the therapeutic window and promoting local activation and immune response against the tumor.

Werewolf Therapeutics Presents Preliminary Monotherapy Data from Phase 1/1b Clinical Trial Establishing Proof of Mechanism for WTX-124 at the Society for Immunotherapy of Cancer’s (SITC) 38th Annual Meeting

Werewolf Therapeutics, Inc. announced preliminary first-in-human clinical data from initial monotherapy dose-escalation cohorts in the Company’s lead clinical program, WTX-124x2101. This clinical program is an ongoing, multi-center Phase 1/1b clinical trial of WTX-124, Werewolf’s interleukin 2 (IL-2) INDUKINE molecule, in patients with advanced or metastatic solid tumors. The preliminary data will be presented now at the Society for Immunotherapy of Cancer’s (SITC) 38th Annual Meeting in San Diego, California. Study WTX-124x2101 is evaluating WTX-124 as a monotherapy and in combination with pembrolizumab in patients with immunotherapy sensitive advanced or metastatic solid tumors who have failed standard of care treatment, including checkpoint inhibitor therapy. The preliminary data include data collected as of October 18, 2023, from 16 heavily pretreated patients from the first four monotherapy dose escalation cohorts (1, 3, 6, 12 mg). The preliminary data established proof of mechanism for WTX-124 and proof of concept for Werewolf’s INDUKINE design. The preliminary data include assessments of safety and tolerability, pharmacokinetics, relevant biomarkers and preliminary antitumor activity. Data as of the October 18, 2023, cutoff date are summarized as follows: WTX-124 was generally well-tolerated at all doses tested up to and including 12 mg in the outpatient setting. All treatment-emergent adverse events (TEAEs) were Grade 1 or Grade 2, and arthralgias and fatigue were the most common TEAEs. Vascular leak syndrome was not observed, and there were no dose limiting toxicities, treatment-related serious adverse events (SAEs) or treatment-related study discontinuations. WTX-124 was delivered intravenously once every two weeks (Q2W). WTX-124 showed expected pharmacokinetics with evidence of wide therapeutic index allowing for continued dose escalation. WTX-124 demonstrated both translational biomarker activity and early evidence of monotherapy antitumor activity at 6 mg and 12 mg doses. CD8+ T and NK cell proliferation and activation in the tumor microenvironment and immune cell gene expression changes were seen at 6 mg and 12 mg dose levels. Among five patients treated at 12 mg, one patient achieved an unconfirmed partial response (uPR), one patient had a restaging scan that was consistent with a partial response as of November 1, 2023, and one other showed evidence of anti-tumor activity. Dose escalation is ongoing in the monotherapy and combination therapy arms of the trial with additional data from monotherapy dose-escalation cohorts informing declaration of recommended dose for expansion (RDE) and opening of the monotherapy expansion arms expected in the first half of 2024. In addition, five preclinical posters further supporting the INDUKINE hypothesis, WTX-124 properties, and other INDUKINE molecules are being presented at the meeting, including: Title: PK/RO Modeling of WTX-124, a Tumor-Activated IL-2 Prodrug, Highlights the Potential for a Substantially Improved Therapeutic Index Compared to Other IL-2 Molecules (Abstract #1074) Plasma and tumor data from mice were used to perform pharmacodynamic and receptor occupancy modeling to predict IL-2 receptor occupancy on peripheral lymphocytes and tumor infiltrating lymphocytes (TILs) suggesting WTX-124 has a substantially improved, best-in-class therapeutic index as compared to other IL-2 molecules investigated, including a half-life extended non-alpha IL-2 and a non-alpha IL-2 tumor-activated prodrug. Title: Optimal Antitumor Immunity Triggered by WTX-124, a Clinical Stage Conditionally Activated INDUKINETM Molecule that Releases Fully Potent IL-2 in the Tumor Microenvironment (Abstract #1058) WTX-124 generated robust anti-tumor activity in a MC38 tumor bearing mouse model and promoted the expansion and activation of tumor specific CD8+ T cells as compared to a variant Non-Alpha IL-2 containing INDUKINE molecule which failed to generate anti-tumor activity, to drive tumor specific CD8+ T cell expansion, or to activate tumor infiltrating immune cells even when dosed up to 28 times higher than the active dose of WTX-124. In addition, while both molecules protected tumor infiltrating CD8+ T cells from exhaustion, only treatment with WTX-124 was able to induce an effector phenotype in tumor specific CD8+ T cells and drive clustering of CD8+ T cells with CD103+ cross presenting dendritic cells within the tumor. Title: Spatial Analysis of Tumor Infiltrating Lymphocyte Populations in Syngeneic Mouse Tumor Models After Treatment with IL-12 (mWTX-330) and IL-2 (WTX-124) INDUKINETM Molecules (Abstract #1059) Combination treatment with WTX-124 and alpha PD-1 generated robust anti-tumor activity in a CT26 model resulting in widespread tumor infiltration by CD8+ T cells driving immune activation in the tumor microenvironment. In addition, detection of structured and unstructured lymphoid aggregates, including the clustering of various adaptive and innate immune cells within the tumor microenvironment suggests a zone of cytotoxic cell education within the tumor microenvironment. Title: The Combination of ACT and INDUKINETM Therapy Leads to Improved Antitumor Immunity in Solid Tumors (Abstract # 252) Systemic WTX-124 was shown to preferentially expand CD4 CAR T cells while WTX-330 expanded CD8 CAR T cells, demonstrating that the administration of INDUKINE proteins with adoptive cell therapy could reinvigorate donor cell function leading to improved immunity, engraftment and long-term responses in solid tumors. Title: Development of WTX-712, a Conditionally Activated IL-21 INDUKINETM Molecule for the Treatment of Cancer (Abstract # 1075) WTX-712 was shown to be peripherally inactive in preclinical studies, releasing IL-21 selectively within the tumor microenvironment while driving CD8+ T cell polyfunctionality and promoting immune cell interactions. In addition, WTX-712 demonstrated enhanced activity when combined with immune checkpoint inhibitors, blocking PD-1/PD-L1 or CTLA-4 pathways, indicating further evaluation of WTX-712 is warranted.
