Celldex Reports Fourth Quarter and Year End 2024 Financial Results and Provides Corporate Update

• Enrollment ongoing in Phase 3 barzolvolimab CSU studies; Phase 3 program in CIndU under development
• Phase 2 barzolvolimab EOE study fully accrued; Phase 2 study initiated in atopic dermatitis; enrollment ongoing in Phase 2 PN study
• Celldex’s first bispecific for inflammatory diseases, CDX-622, Phase 1 study initiated
• Multiple important data read outs anticipated in 2025

HAMPTON, N.J., Feb. 27, 2025 (GLOBE NEWSWIRE) -- Celldex Therapeutics, Inc. (NASDAQ:CLDX) today reported financial results for the fourth quarter and year ended December 31, 2024 and provided a corporate update.

"In 2024, Celldex set a new bar for efficacy in chronic urticarias—presenting best-in-disease data across both our Phase 2 studies in CSU and CIndU,” said Anthony Marucci, Co-founder, President and Chief Executive Officer of Celldex Therapeutics. “Our Phase 3 studies in CSU have been met with great enthusiasm from the global medical community and are actively enrolling patients around the world. We look forward to building on this momentum later this year when we initiate our Phase 3 program in CIndU.”

“We closed 2024 with the initiation of two new programs—advancing barzolvolimab into its fifth indication, atopic dermatitis, and expanding our leadership in mast cell science with the introduction of our first inflammatory bispecific candidate into the clinic, CDX-622, which targets stem cell factor and TSLP,” added Mr. Marucci. “We expect 2025 will be a year of continued execution across our robust pipeline supported by important data from our barzolvolimab Phase 2 studies in CSU, CIndU and EOE and our CDX-622 Phase 1 study in healthy volunteers. We’re excited to continue this work and share our progress over the course of the year.”

Recent Program Highlights

Barzolvolimab - KIT Inhibitor Program

Barzolvolimab is a humanized monoclonal antibody developed by Celldex that binds the KIT receptor with high specificity and potently inhibits its activity. The KIT receptor tyrosine kinase is expressed in a variety of cells, including mast cells, which mediate inflammatory responses such as hypersensitivity and allergic reactions. KIT signaling controls the differentiation, tissue recruitment, survival and activity of mast cells. 

Chronic Urticarias

Phase 3 Development

• A global Phase 3 program in chronic spontaneous urticaria (CSU) consisting of two Phase 3 trials (EMBARQ-CSU1 and EMBARQ-CSU2) was initiated in July and enrollment is ongoing. The studies are designed to establish the efficacy and safety of barzolvolimab in adult patients with CSU who remain symptomatic despite H1 antihistamine treatment and also include patients who remain symptomatic after treatment with biologics. EMBARQ-CSU1 and EMBARQ-CSU2 will enroll approximately 915 patients each across 40 countries and 500 sites.
  
  
• The Company is currently planning a global Phase 3 program in chronic inducible urticaria (CIndU), which is expected to initiate in 2025.
  

Phase 2 Development

• Barzolvolimab met all primary and secondary endpoints at 12 weeks across the Company’s Phase 2 studies in CSU and CIndU. Results were highly statistically significant and clinically meaningful.
  
  
  • 52 week data from the Phase 2 study in CSU (n=208) were presented in a late breaking oral presentation at the EADV Congress 2024. A deepening of response was observed over the 52 week treatment period and barzolvolimab demonstrated the highest rate of complete response observed in a well controlled study in CSU with 71% of patients (150 mg Q4W) achieving a complete response at Week 52. Importantly, barzolvolimab was also well tolerated through 52 weeks. The Company anticipates presenting 76 week data (52 weeks of treatment; 24 weeks of follow up post treatment) from the study in 2025.
    
    
  • 12 week primary endpoint data from the Phase 2 study in CIndU (n=196) were presented in a late breaking oral presentation at the ACAAI Annual Scientific Meeting 2024. Barzolvolimab is the first drug to demonstrate clinical benefit in patients with chronic inducible urticaria in a large, randomized, placebo-controlled study. Up to 53.1% of patients with cold urticaria (ColdU) and 57.6% of patients with symptomatic dermographism (SD) treated with barzolvolimab experienced a complete response (per provocation test) compared to placebo rates of only 12.5% (p=0.0011) in ColdU and 3.2% (p<0.0001) in SD—the primary endpoint of the study. Secondary and exploratory endpoints were highly supportive of the primary endpoint. Patients on study continued to receive barzolvolimab or placebo for up 20 weeks and are being followed for an additional 24 weeks. The study also includes an Open Label Extension. The Company anticipates presenting data through week 44 in 2025 (20 weeks of treatment; 24 weeks of follow up post treatment; patients with returning symptoms can enter open label extension during follow up period).
    

Additional Indications

• A Phase 2 study in eosinophilic esophagitis (EoE) is fully accrued. This randomized, double-blind, placebo-controlled, parallel group study is evaluating the efficacy and safety profile of barzolvolimab in patients with active EoE. Data from this study is expected in 2025.
  
  
• Enrollment continues in the Phase 2 study in prurigo nodularis (PN). This randomized, double-blind, placebo-controlled, parallel group study is evaluating the efficacy and safety profile of barzolvolimab in approximately 120 patients with moderate to severe PN who had inadequate response to prescription topical medications, or for whom topical medications are medically inadvisable, including patients who received prior biologics.
  
  
• A Phase 2 study in atopic dermatitis (AD) was initiated in December 2024 and enrollment is ongoing. This randomized, double-blind, placebo-controlled, parallel group study is evaluating the efficacy and safety profile of barzolvolimab in approximately 120 patients with moderate to severe AD.
  

Bispecific Antibody Platform

CDX-622 – Bispecific SCF & TSLP

CDX-622 targets two complementary pathways that drive chronic inflammation, potently neutralizing the alarmin thymic stromal lymphopoietin (TSLP) and depleting mast cells via stem cell factor (SCF) starvation. Combined neutralization of SCF and TSLP with CDX-622 is expected to simultaneously reduce tissue mast cells and inhibit Type 2 inflammatory responses to potentially offer enhanced therapeutic benefit in inflammatory and fibrotic disorders.

• A Phase 1 study in healthy volunteers was initiated in November 2024 and enrollment is ongoing. This two-part randomized, double-blind, placebo-controlled, Phase 1 dose escalation study is designed to assess the safety, pharmacokinetics, and pharmacodynamics of single ascending doses (Part 1) and multiple ascending doses (Part 2) of CDX-622 in up to 56 healthy participants. The pharmacodynamic biomarkers from blood and skin will be highly informative on the ability of CDX-622 to engage and neutralize SCF and TSLP.
  

Fourth Quarter and Twelve Months 2024 Financial Highlights and 2025 Guidance

Cash Position: Cash, cash equivalents and marketable securities as of December 31, 2024 were $725.3 million compared to $756.0 million as of September 30, 2024. The decrease was primarily driven by fourth quarter cash used in operating activities of $32.5 million. At December 31, 2024, Celldex had 66.4 million shares outstanding.

Revenues: Total revenue was $1.2 million in the fourth quarter of 2024 and $7.0 million for the year ended December 31, 2024, compared to $4.1 million and $6.9 million for the comparable periods in 2023. The decrease in revenue for the fourth quarter of 2024, as compared to the fourth quarter of 2023, was primarily due to a decrease in services performed under our manufacturing and research and development agreements with Rockefeller University.

R&D Expenses: Research and development (R&D) expenses were $46.9 million in the fourth quarter of 2024 and $163.6 million for the year ended December 31, 2024, compared to $30.4 million and $118.0 million for the comparable periods in 2023. The increase in R&D expenses was primarily due to an increase in barzolvolimab clinical trial and personnel expenses, partially offset by a decrease in barzolvolimab contract manufacturing expenses.

G&A Expenses: General and administrative (G&A) expenses were $10.3 million in the fourth quarter of 2024 and $38.5 million for the year ended December 31, 2024, compared to $8.8 million and $30.9 million for the comparable periods in 2023. The increase in G&A expenses was primarily due to an increase in stock-based compensation and barzolvolimab commercial planning expenses.

Litigation Settlement Related Loss: During the fourth quarter of 2023, the Company announced positive topline results from its Phase 2 clinical trial of barzolvolimab in patients with moderate to severe CSU, satisfying the “Successful Completion” of a Phase 2 clinical trial of barzolvolimab milestone pursuant to the Company’s settlement agreement with SRS. During the fourth quarter of 2023, we paid the $12.5 million milestone in cash and recorded a litigation settlement related loss of $12.5 million.

Net Loss: Net loss was $47.1 million, or ($0.71) per share, for the fourth quarter of 2024, and $157.9 million, or ($2.45) per share, for the year ended December 31, 2024, compared to a net loss of $43.3 million, or ($0.83) per share, for the fourth quarter of 2023, and $141.4 million, or ($2.92) per share, for the year ended December 31, 2023.

Financial Guidance: Celldex believes that the cash, cash equivalents and marketable securities at December 31, 2024 are sufficient to meet estimated working capital requirements and fund current planned operations through 2027.
