Why is Evommune stock tumbling today?
Evommune's stock fell 16.4% to $10.93 after its drug EVO756 failed Phase 2b trials for atopic dermatitis. The company will not advance the drug for this condition but will continue testing for migraine prophylaxis. This is the second Phase 2b failure for EVO756 in 2026. Evercore ISI maintained a Buy rating, but broader market declines also pressured the stock.
