Vanda Pharmaceuticals Phase III trial of VQW‑765 fails to meet primary endpoint

Vanda Pharmaceuticals announced that its Phase III study of VQW‑765 in adults with social anxiety disorder did not achieve statistical significance on the primary endpoint of distress in female participants, nor on the key secondary endpoint in the overall population. The multicenter trial enrolled 546 patients across about 30 U.S. sites and was double‑blind, placebo‑controlled. The company has placed the VQW‑765 program on hold pending a full data analysis.

Shares fell about 6.2% after the announcement. Oppenheimer analysts said the miss does not alter their earnings estimates for Vanda.
