Quimilza FDA decision • 2026-12-12

Base target: $4 / p=45% prob

Biggest risk

The October 14 Phase III VQW-765 study missed both its primary and key secondary endpoints, and Vanda placed the social-anxiety program on hold pending full-data analysis. That removes a previously anticipated 2026 readout from the upside case. Vanda release.

Invalidation

Break below $3 or thesis failure.

What would change my mind?

Fanapt Q2 sales rose 23% year over year to $36.0 million, while Vanda reported $170.0 million of June-end cash and expected funding through at least 2027. Quimilza approval, a positive NEREUS readout, or progress toward a HETLIOZ sNDA could support upside. [#SEC-8K-2026-08-05] SEC-filed company release.

Commentary

The positive September HETLIOZ result was followed by the October 14 VQW-765 failure, a material deterioration from the prior speculative-buy thesis. Reuters reported shares down about 17% in extended trading immediately after the failure; the packet's later October 21 anchor is $4.01. Reuters. No verified post-print analyst revisions, options skew, short-interest, employee score, or sufficient social measure were available; zero-valued fields denote missing data, not neutral readings. The deterministic prior remains positive, but the failed trial and thin target coverage limit conviction.

Quimilza could receive an FDA delay or rejection on its December 12 target date. [#SEC-8K-2026-08-05].
The HETLIOZ sleep-disorder trial analyzed only 20 patients per arm on its primary endpoint, and an sNDA has not yet been filed. [#PR-EARNINGS-2026-09-29].
VQW-765 showed virtually no separation from placebo on its primary endpoint (65.6 versus 66.0; p=0.8899), and the program is on hold. Vanda release.
Vanda cautioned that anticipated developments may not be realized or have their expected effects. [#8-K-2026-08-05].

Peers

Symbol	Summary
ACAD	Commercial CNS-drug comparator for launch execution, but its larger revenue base and different indications make its valuation multiple a poor direct benchmark for VNDA.
SUPN	Marketed neurology and psychiatry medicines provide operating context, but its broader portfolio and different scale limit valuation comparability.
