HAMPTON, N.J., Aug. 08, 2024 (GLOBE NEWSWIRE) -- Celldex Therapeutics, Inc. (NASDAQ:CLDX) today reported financial results for the second quarter ended June 30, 2024 and provided a corporate update.

“2024 has been a monumental year for Celldex. We presented data establishing clinical benefit and safety for barzolvolimab in two distinct forms of urticaria—chronic spontaneous urticaria and inducible urticaria—both of which support advancement to registration studies,” said Anthony Marucci, Co-founder, President and Chief Executive Officer of Celldex Therapeutics. “Last month, we initiated two of the largest, global studies to be conducted in CSU and we are now planning for the initiation of a second Phase 3 program in CIndU. With ongoing Phase 2 trials also in prurigo nodularis, eosinophilic esophagitis and, by year end, in atopic dermatitis—barzolvolimab is actively delivering on its significant pipeline in a product potential and we remain committed to our goal of bringing this potential new medicine to patients.”

Mr. Marucci continued, “As the year progresses, we continue to build on our leadership in the development of mast cell-targeted therapeutics and plan to advance CDX-622, our first bispecific for inflammatory diseases, into the clinic by year end. We think this candidate is an exciting entrant to the field, targeting two complementary pathways that drive chronic inflammation, TSLP and stem cell factor. Importantly, the Company is well capitalized with more than $800M in cash to support the continued advancement and expansion of the barzolvolimab program and our growing pipeline.”

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

• Celldex initiated a global Phase 3 program in chronic spontaneous urticaria (CSU) in July, consisting of two Phase 3 trials (EMBARQ-CSU1 and EMBARQ-CSU2) designed to establish the efficacy and safety of barzolvolimab in adult patients with CSU who remain symptomatic despite H1 antihistamine treatment. The studies will also include patients who remain symptomatic after treatment with biologics. Both studies are actively enrolling patients.
  
  
• Celldex is completing Phase 2 clinical studies of barzolvolimab for the treatment of chronic spontaneous urticaria (CSU) and the two most common forms of chronic inducible urticaria (CIndU) - cold urticaria (ColdU) and symptomatic dermographism (SD). These randomized, double-blind, placebo-controlled Phase 2 studies are evaluating the efficacy and safety profile of multiple dose regimens of barzolvolimab in patients who remain symptomatic despite antihistamine therapy, to determine the optimal dosing strategies.
  
  
  • In July 2024, the Company reported topline 12 week primary endpoint results from the Phase 2 CIndU study. Data from the 196 patients randomized in the study showed that barzolvolimab achieved the primary efficacy endpoint, a statistically significant difference between the percent of patients with a negative provocation test (complete response) compared to placebo at Week 12, in ColdU and in SD across both dose groups. Importantly, barzolvolimab demonstrated rapid, durable and clinically meaningful responses. Barzolvolimab was well tolerated with a favorable safety profile consistent with prior studies. Patients on study will continue to receive barzolvolimab for 20 weeks and the Company plans to present the full 12 week data from this study at an upcoming medical meeting in the second half of 2024.
    
    
  • In February 2024, 12 week treatment results were reported from the Phase 2 CSU study at the American Academy of Allergy, Asthma & Immunology (AAAAI) Annual Meeting. Barzolvolimab achieved the primary efficacy endpoint of the study, a statistically significant mean change from baseline to Week 12 of UAS7 (weekly urticaria activity score) compared to placebo across multiple dosing groups, and was well tolerated. Secondary and exploratory endpoints strongly support the primary endpoint results. Importantly, barzolvolimab demonstrated rapid, durable and clinically meaningful responses, including in patients with prior omalizumab treatment. Patients on study continue to receive barzolvolimab for 52 weeks and the Company plans to report 52 week data in the second half of 2024.
    
    In June 2024, data from this study on the impact of barzolvolimab on angioedema were presented at the European Academy of Allergy and Clinical Immunology (EAACI) Congress 2024. Barzolvolimab profoundly improved angioedema at 12 weeks, demonstrating statistically significant, rapid and durable improvements in the weekly angioedema activity score (AAS7) and additional measures of angioedema control across all doses at Week 12.
    

Additional Indications

• A Phase 2 study in prurigo nodularis (PN) was initiated in early 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 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 eosinophilic esophagitis (EoE) was initiated in July 2023 and enrollment is ongoing. This randomized, double-blind, placebo-controlled study is evaluating the efficacy and safety profile of barzolvolimab in approximately 75 patients with active EoE.
  
  
• In May 2024, Celldex announced that atopic dermatitis (AD) has been selected as the fifth indication for the development of barzolvolimab. Barzolvolimab’s novel mast cell depleting mechanism could play an important role in addressing patients with moderate to severe AD who do not achieve complete disease control on currently available systemic therapies. Celldex plans to initiate a Phase 2 study in AD by year end.
  

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.

• Celldex has completed preclinical, manufacturing and IND-enabling activities for CDX-622 and plans to initiate a Phase 1 study of the candidate in healthy volunteers by the end of 2024. In preclinical studies, CDX-622 inhibits TSLP and SCF with similar potency to both its respective parental mAbs and comparator mAbs in vitro. CDX-622 was well tolerated in a multi-dose 8 week toxicology study in non-human primates and the No Adverse Event Level (NOAEL) was established to be 75 mg/kg, the highest dose level tested. In inflammatory and fibrotic disorders, TSLP is often upregulated and associated with disease severity. Similarly, mast cells drive or contribute to the pathophysiology of many of these disorders and CDX-622 contains a unique SCF neutralizing function that is expected to inhibit and deplete mast cells.
  

CDX-585 – Bispecific ILT4 & PD-1

CDX-585 combines highly active PD-1 blockade with anti-ILT4 blockade to overcome immunosuppressive signals in T cells and myeloid cells. ILT4 is emerging as an important immune checkpoint on myeloid cells.

• In May 2023, the first patient was dosed in the Phase 1 study of CDX-585. This open-label, multi-center study of CDX-585 is evaluating patients with advanced or metastatic solid tumors that have progressed during or after standard of care therapy. Enrollment is ongoing in the dose-escalation portion of the study.
  

Second Quarter 2024 Financial Highlights and 2024 Guidance

Cash Position: Cash, cash equivalents and marketable securities as of June 30, 2024 were $802.3 million compared to $823.8 million as of March 31, 2024. The decrease was primarily driven by second quarter cash used in operating activities of $29.3 million, partially offset by proceeds from issuance of stock under employee benefit plans of $3.7 million. At June 30, 2024, Celldex had 66.3 million shares outstanding.

Revenues: Total revenue was $2.5 million in the second quarter of 2024 and $2.7 million for the six months ended June 30, 2024, compared to $0.3 million and $1.2 million for the comparable periods in 2023. The increase in revenue was primarily due to an increase in services performed under our manufacturing and research and development agreements with Rockefeller University.

R&D Expenses: Research and development (R&D) expenses were $39.7 million in the second quarter of 2024 and $71.3 million for the six months ended June 30, 2024, compared to $26.3 million and $53.0 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 $9.1 million in the second quarter of 2024 and $18.2 million for the six months ended June 30, 2024, compared to $7.2 million and $13.9 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.

Net Loss: Net loss was $35.8 million, or ($0.54) per share, for the second quarter of 2024, and $68.7 million, or ($1.10) per share, for the six months ended June 30, 2024, compared to a net loss of $30.5 million, or ($0.65) per share, for the second quarter of 2023, and $59.9 million, or ($1.27) per share, for the six months ended June 30, 2023.

Financial Guidance: Celldex believes that the cash, cash equivalents and marketable securities at June 30, 2024 are sufficient to meet estimated working capital requirements and fund current planned operations through 2027.
