Insights

Financial Analyst

Mural Oncology's Q2 2024 results reveal a mixed financial picture. The company's cash position of $204.7 million and projected runway into Q4 2025 provide stability. However, the net loss of $31.6 million, while improved from Q2 2023, remains significant. R&D expenses decreased by 35.3%, primarily due to winding down of certain trials and changes in team composition post-separation from Alkermes. G&A expenses increased by 42.6%, reflecting costs of operating independently. The financial guidance suggesting lower operating expenses in 2025 is positive, but investors should monitor cash burn rate closely given the company's pre-revenue stage.

Oncology Research Analyst

Mural's pipeline progress is promising, particularly with nemvaleukin alfa. The completion of patient enrollment in ARTISTRY-7 and expected readouts in 1H 2025 for both ARTISTRY-7 and ARTISTRY-6 are critical milestones. The less frequent IV dosing data presented at ASCO is encouraging, potentially improving patient convenience without compromising efficacy. The preclinical IL-18 and IL-12 programs, with candidate nominations expected this year, demonstrate Mural's commitment to expanding its cytokine portfolio. However, investors should note that success in preclinical stages doesn't guarantee clinical efficacy. The focus on indications with treatment options, such as platinum-resistant ovarian cancer and mucosal melanoma, could provide significant market opportunities if trials are successful.

Market Research Analyst

The resurgent interest in cytokines across the industry positions Mural favorably. Their engineered approach to overcoming limitations of previous cytokine therapies could be a key differentiator. The appointment of Dr. Golumbeski to the board adds valuable expertise in strategic collaborations and M&A, potentially opening doors for future partnerships or acquisitions. However, Mural faces a highly competitive landscape in immuno-oncology. The company's success will hinge on the clinical performance of nemvaleukin alfa and the progression of its preclinical programs. Investors should closely monitor upcoming trial readouts and compare Mural's results with those of competitors to gauge potential market impact.

Company remains well positioned to capitalize on the role of cytokines with near- and long-term potential value creation milestones, reiterates guidance on projected cash runway into Q4 2025

WALTHAM, Mass and DUBLIN, Aug. 13, 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 financial results for the second quarter of 2024 and provided a business update.

"We’ve seen resurgent interest across the industry in cytokines as powerful tools to fight cancer and Mural is in a unique position to deliver promising drug candidates that have the potential to overcome the limitations of prior approaches,” said Caroline Loew, Ph.D., Chief Executive Officer of Mural Oncology. “Since becoming an independent company late last year, we’ve rapidly worked to shape and grow a nimble organization focused on delivering meaningful new immunotherapy treatments to cancer patients. We believe each of our programs is engineered with a differentiated approach that we hope will play out significantly in the clinic starting early next year.”

Recent Corporate Highlights and Upcoming Milestones

• Mural appointed George Golumbeski, Ph.D., to its board of directors in July. Dr. Golumbeski currently serves as a partner at DROIA Ventures, a specialist biotech investment firm focused on therapeutics for oncology and genetic disease. Prior to DROIA, he served as President and Head of Corporate Development for GRAIL and Executive Vice President of Business Development for Celgene. He has nearly 30 years of extensive experience with strategic collaborations, M&A, in-licensing, out-licensing, and alliance management. 
• Mural’s late-stage clinical trials of nemvaleukin alfa continue to progress toward readouts in the first half of 2025. The company is focused on two foundational indications for nemvaleukin, where the majority of patients do not have any currently approved therapies.
    
  • ARTISTRY-7 is a potentially registrational, phase 3 clinical trial evaluating nemvaleukin in combination with pembrolizumab compared to investigators’ choice of chemotherapy in patients with platinum-resistant ovarian cancer. Patient enrollment in this trial is now complete. Mural continues to expect to report interim overall survival (OS) results based on approximately 75% of events in the first quarter of 2025. The company anticipates reporting final OS results in the second quarter of 2026. 
  • Mural expects to report top-line data results from cohort 2 of ARTISTRY-6 in the first half of 2025. This is a potentially registrational, phase 2 clinical trial evaluating nemvaleukin as a monotherapy in patients with mucosal melanoma.
    
  • Mural is also evaluating a less-frequent intravenous (LFIV) dose of nemvaleukin in patients with cutaneous melanoma in cohort 3 (monotherapy) and cohort 4 (combination therapy) in ARTISTRY-6. The company expects preliminary data readouts in the monotherapy cohort in the first half of 2025, and in the combination cohort with pembrolizumab in the second half of 2025. 
  • In June, Mural presented data from ARTISTRY-3, an evaluation of the LFIV dosing of nemvaleukin, at the American Society of Clinical Oncology (ASCO) annual meeting. This data from ARTISTRY-3 informed the LFIV dose currently being used in cohort 3 and cohort 4 of ARTISTY-6. In the ARTISTRY-3 trial, the company evaluated escalating LFIV infusions, all of which were generally well tolerated. The safety profile in all dosing schedules evaluated was consistent with nemvaleukin’s known mechanism of action, and no dose limiting toxicities were observed. Although administering higher doses per cycle than in previous trials evaluating nemvaleukin, no new safety signals were identified. The desired pharmacodynamic (PD) effects were also seen across all evaluated doses. Expansion of antitumor CD8+ T cells and natural killer (NK) cells was observed concurrent with minimal expansion of immunosuppressive regulatory T cells (T_regs).
    
    
• Mural’s preclinical interleukin-18 (IL-18) and IL-12 programs remain on track, with nominations for both development candidates expected this year.
    
  • Mural’s enhanced IL-18 is engineered to deliver a more sustained immune response for cancer treatment. Native 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 with and neutralizes IL-18, thereby rendering it ineffective. Native IL-18 is also limited by its short half-life. Mural’s IL-18 variant contains mutations that eliminate binding to IL-18BP while minimally impacting the native IL-18 structure. The company has also fused IL-18 to protein scaffolds to extend the half-life and increase IL-18’s exposure. Together, Mural believes these have demonstrated a more durable immunological effect in preclinical studies.
    
  • The company’s enhanced IL-12 is engineered to leverage native IL-12’s anti-tumor potency while mitigating its hallmark toxicity. Native IL-12 is a highly potent pro-inflammatory cytokine, but because of its very narrow therapeutic index, it can also be incredibly toxic with systemic exposure. Mural’s IL-12 variant splits the molecule into two inactive monomers, and these individual subunits are then separately fused to antibody fragments and sequentially injected, which deliver and concentrate IL-12 specifically in the tumor microenvironment with the goal of limiting systemic exposure. In preclinical studies, Mural believes its engineered IL-12 achieved the desired reduction in serum while maintaining tumor concentrations providing the potential to reduce systemic toxicities.

Financial Results for the Quarter Ended June 30, 2024

• Cash Position: As of June 30, 2024, cash, cash equivalents, and marketable securities were $204.7 million. 
• R&D Expenses: Research and development expenses were $27.5 million for the second quarter of 2024 compared to $42.5 million for the second quarter of 2023. The decrease in R&D expenses was primarily due to different team composition compared to the personnel allocated to us by Alkermes, our former parent, prior to the separation, as well as decreased spend on the ARTISTRY-1 and ARTISTRY-2 trials as activities related to these trials wound down in 2023 and decreased spend on the ARTISTRY-7 trial due to the timing of patient enrollment. 
• G&A Expenses: General and administrative expenses were $6.7 million for the second quarter of 2024 compared to $4.7 million for the second quarter of 2023. The increase in expenses was primarily due to costs associated with operating as a standalone company after the separation. This includes employee-related expenses and professional fees. 
• Net Loss: Net loss was $31.6 million for the second quarter of 2024 compared to $50.2 million for the second quarter of 2023.

Financial Guidance

• The company reaffirms guidance that its cash, cash equivalents, and marketable securities are expected to fund its operations into the fourth quarter of 2025. 
• As noted previously, management forecasts lower operating expenses in 2025 versus 2024 due to the timing of clinical trial expenses.

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.

About Mural Oncology’s IL-12 Program
Native IL-12 is a highly potent pro-inflammatory cytokine, but because of its very narrow therapeutic index, it can also be toxic with systemic exposure. To mitigate this hallmark toxicity, Mural, through its novel approach to protein engineering, split the IL-12p70 heterodimer into two inactive monomers: IL12p35 and IL-12p40. These individual subunits are then separately fused to antibody fragments and sequentially injected, which deliver and concentrate IL-12 specifically in the tumor microenvironment to limit systemic exposure. In preclinical studies, Mural’s engineered IL-12 achieved the desired reduction in serum while maintaining tumor concentrations providing the potential to reduce systemic toxicities. Mural intends to nominate a development candidate for its IL-12 program by the end of this year.
