CLDX Stock Slumps 11% – This Analyst Sees Nearly 90% Upside, Calls Phase 3 Trial Safety Concerns ‘Misplaced’
Celldex Therapeutics (CLDX) stock fell 11% despite positive Phase 3 trial results for Barzolvolimab, its treatment for chronic spontaneous urticaria. H.C. Wainwright raised its price target to $64, citing nearly 90% upside potential. The studies met primary and secondary endpoints, but safety concerns, including two cases of probable Grade 4 anaphylaxis, led to the initial sell-off. Celldex plans to file for FDA approval in 2027.
