Is Celldex (CLDX) Using Barzolvolimab’s Phase 3 Urticaria Bet To Redefine Its Core Strategy?

Simply Wall St·12/21/2025 18:21:16
Listen to the news
  • In December 2025, Celldex Therapeutics began a global Phase 3 EMBARQ-ColdU and SD trial of barzolvolimab in adults with cold urticaria and symptomatic dermographism who remain symptomatic despite H1 antihistamines or biologics, enrolling about 240 patients across approximately 75 sites in 7 countries with complete response at Week 12 as the primary endpoint.
  • This late-stage program builds directly on earlier placebo-controlled Phase 2 data showing rapid, durable clinical responses and meaningful quality-of-life improvements in these highly burdened chronic inducible urticaria populations.
  • We’ll now examine how advancing barzolvolimab into a global Phase 3 program for hard-to-treat urticaria shapes Celldex’s investment narrative.

What Is Celldex Therapeutics' Investment Narrative?

To own Celldex today, you really have to believe barzolvolimab can convert strong mid‑stage data into a real commercial franchise across multiple urticaria settings, and eventually beyond. The EMBARQ Phase 3 launch is a clear step toward that, and while the market’s recent muted share price reaction suggests expectations were already reasonably high, it still sharpens near to medium term catalysts around Phase 3 readouts, partnering potential and financing needs. At the same time, the company’s small revenue base, sizeable losses of over US$200,000,000 in the last reported twelve months, and forecasts for continued unprofitability keep funding risk very much in focus. This new trial raises Celldex’s execution bar: success could reshape the story, but setbacks would matter.

However, one key funding risk could catch shareholders off guard if timelines slip. Upon reviewing our latest valuation report, Celldex Therapeutics' share price might be too optimistic.
