Mural Oncology to Host First Virtual Investor Day on September 26, 2024

Company will provide clinical overview and update on late-stage clinical candidate, nemvaleukin alfa, and overview of IL-18 pipeline program

Clinicians to share expert perspectives around the potential of new cytokine-based immunotherapies

Mural remains on track to deliver key data readouts in potentially registrational trials of nemvaleukin in platinum-resistant ovarian cancer and mucosal melanoma in 1H 2025

WALTHAM, Mass. and DUBLIN, Sept. 10, 2024 (GLOBE NEWSWIRE) — Mural Oncology plc (Nasdaq: MURA), a clinical-stage immuno-oncology company developing novel, investigational engineered cytokine therapies designed to address areas of unmet need for patients with a variety of cancers, today announced that it will host a virtual Investor Day on Thursday, September 26, 2024, beginning at 10 a.m. ET.

Mural leadership, including Caroline Loew, Ph.D., CEO, and Vicki Goodman, MD, Chief Medical Officer, will provide new clinical insight into the trial design and assumptions of the company’s late-stage and potentially registrational trials of nemvaleukin, an engineered IL-2. Those trials are on track to deliver topline results in 1H 2025. Mural will also provide an overview and data presentation of its IL-18 program.

The Investor Day will also feature clinician discussion as follows:

• Clinical proof of concept of Mural’s lead program, nemvaleukin: Ulka Viashampayan, MD, Professor, Internal Medicine, Division of Hematology/Oncology, University of Michigan
• Unmet need in platinum-resistant ovarian cancer: John Hays, MD, PhD, an associate professor in the Divisions of Medical Oncology and Gynecologic Oncology, and member of the Translational Therapeutics Program at The Ohio State University Comprehensive Cancer Center
• Mucosal melanoma and need for dedicated treatments: Rich Carvajal, MD, Deputy Physician-in-Chief and Director of Medical Oncology at the Northwell Health Cancer Institute

The event will conclude with a live Question & Answer section.

About Nemvaleukin
Nemvaleukin alfa (nemvaleukin) is a novel, engineered cytokine designed to leverage antitumor effects of the IL-2 pathway while mitigating the hallmark toxicities that limit its use. Nemvaleukin selectively binds to the intermediate-affinity IL-2 receptor (IL-2R) and is sterically occluded from binding to the high-affinity IL-2R. Because of this molecular design, nemvaleukin treatment leads to preferential expansion of antitumor CD8+ T cells and natural killer cells, with minimal expansion of immunosuppressive regulatory T cells. Nemvaleukin is currently being evaluated in two potentially registrational late-stage trials.

About Mural Oncology’s IL-18 Program
IL-18 is a potent immune-stimulating cytokine, but its efficacy is blunted by IL-18 binding protein (IL-18BP), a high affinity decoy receptor that binds to, and neutralizes, IL-18, thereby rendering it ineffective. Native IL-18’s potency is also limited by its short half-life. Mural Oncology’s novel approach to protein engineering is designed to mitigate these issues. First, Mural introduced mutations to IL-18 that eliminate binding to IL-18BP while minimally impacting the native IL-18 structure. Second, it fused IL-18 to protein scaffolds which extend the half-life and increase IL-18’s exposure. Together, these have demonstrated more durable immunological effect in preclinical studies. Mural intends to nominate a development candidate for its IL-18 program by the end of this year.
