HAMPTON, N.J., May 06, 2024 (GLOBE NEWSWIRE) -- Celldex Therapeutics, Inc. (NASDAQ:CLDX) today reported financial results for the first quarter ended March 31, 2024 and provided a corporate update.

"During the first quarter we presented impressive best-in-field data from a large, randomized Phase 2 study in CSU,” said Anthony Marucci, Co-founder, President and Chief Executive Officer of Celldex Therapeutics. “These results added to a rapidly growing body of data across multiple indications that support barzolvolimab’s impressive potential to treat mast cell mediated diseases. This year, we continue to expand barzolvolimab’s profile and, based on its unique mechanism of action and demonstrated improvement in pruritus, we are actively planning for the initiation of a Phase 2 study in atopic dermatitis, a setting where mast cell numbers are known to be increased and activated in the lesions associated with the disease and where, despite established systemic therapies, a significant unmet need still exists.”

Mr. Marucci continued, “As the year progresses, we look forward to building on our leadership in the development of mast cell-targeted therapeutics. Importantly, the Company is well capitalized with more than $820M in cash to support the continued advancement and expansion of the barzolvolimab program and the introduction of our first bispecific for inflammatory diseases later this 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. 

  • Celldex is conducting 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.

    • Celldex is currently planning two Phase 3 studies of barzolvolimab in CSU, which are expected to initiate this summer.

    • 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 in a late breaking oral presentation. Barzolvolimab achieved the primary efficacy endpoint of the study, with 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 in the study, including ISS7 (weekly itch severity score) and HSS7 (weekly hives severity score) and responder analyses strongly support the primary endpoint results. Importantly, barzolvolimab demonstrated rapid, durable and clinically meaningful responses in patients with moderate to severe CSU refractory to antihistamines, including patients with prior omalizumab treatment. Approximately 20% (n=41) of enrolled patients received prior treatment with omalizumab and more than half of these patients had omalizumab-refractory disease. These patients experienced a similar clinical benefit as the overall treated population within their individual dosing groups consistent with the barzolvolimab mechanism of action. Patients on study will continue to receive barzolvolimab for 52 weeks and the Company plans to report 52 week data in the second half of 2024.

      Data from this study on the impact of barzolvolimab on angioedema have been accepted for an oral presentation at the European Academy of Allergy and Clinical Immunology (EAACI) Congress 2024 on Saturday, June 2nd from 3:00-4:30 CET in Valencia, Spain (9:00-10:30 am ET).

    • Enrollment to the Phase 2 CIndU study has been completed and 12 week primary endpoint data from this study are expected to be reported in the second half of 2024. The study enrolled 196 patients—97 patients with cold urticaria and 99 patients with symptomatic dermographism.
  • A Phase 2 subcutaneous study in prurigo nodularis (PN) was initiated in early 2024. 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. Patients are receiving barzolvolimab injections of 150 mg Q4W after an initial loading dose of 450 mg, 300 mg Q4W after an initial loading dose of 450 mg, or placebo during a 24‑week Treatment Phase.
  • In July 2023, the first patient was dosed in the Phase 2 randomized, double-blind, placebo-controlled study in eosinophilic esophagitis (EoE); enrollment is ongoing. To optimize potential efficacy signal in this difficult to treat indication, in early 2024, the protocol was amended to dose 300 mg every 4 weeks rather than 8 weeks. Approximately 75 patients will be enrolled in total.
  • Atopic Dermatitis has been selected as the fifth indication for the development of barzolvolimab. Atopic dermatitis (AD) is a chronically relapsing, inflammatory skin disease that is typified by pruritus (itching), eczematous lesions, dry skin, thickening of the skin and an increase in skin markings. AD is the most common inflammatory skin condition, with a lifetime prevalence of up to 20% and has a high itch burden—almost 90% of individuals with AD experience daily itching and 60% describe their itching as severe or unbearable. 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. Mast cell numbers are increased and activated in AD lesions and produce key TH2 cytokines and neuropeptides that trigger disease progression and itch. Barzolvolimab has demonstrated impressive anti-pruritic effects in other itch driven conditions, including chronic urticarias and prurigo nodularis. Celldex plans to initiate a Phase 2 study in AD by year end.

Bispecific Antibody Platform

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.

First Quarter 2024 Financial Highlights and 2024 Guidance

Cash Position: Cash, cash equivalents and marketable securities as of March 31, 2024 were $823.8 million compared to $423.6 million as of December 31, 2023. The increase was primarily driven by net proceeds of $432.3 million from our March 2024 underwritten public offering, partially offset by cash used in operating activities of $40.6 million. At March 31, 2024, Celldex had 65.9 million shares outstanding.

Revenues: Total revenue was $0.2 million in the first quarter of 2024, compared to $1.0 million for the comparable period in 2023. The decrease in revenue 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 $31.7 million in the first quarter of 2024, compared to $26.8 million for the comparable period 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 first quarter of 2024, compared to $6.6 million for the comparable period 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 $32.8 million, or ($0.56) per share, for the first quarter of 2024, compared to a net loss of $29.4 million, or ($0.62) per share, for the comparable period in 2023.

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