Recent FDA Decision Affects Vanda Pharmaceuticals' Stock
On January 8, 2026, Vanda Pharmaceuticals issued a press release noting the receipt of a decision letter from the U.S. Food and Drug Administration (FDA) regarding the supplemental New Drug Application (sNDA) for HETLIOZ® (tasimelteon), targeting the treatment of jet lag disorder. The FDA stated that it could not approve the application in its current format.
This announcement has significant implications for Vanda Pharmaceuticals and its shareholders. The FDA recognized positive efficacy from Vanda's controlled clinical trials but concluded that these data did not present substantial evidence of effectiveness for jet lag disorder. Specifically, the FDA indicated that the protocols utilized in the trials (5-hour and 8-hour bedtime shifts) are not sufficiently comparable to actual jet travel, which entails additional variables like
- Reduced oxygen pressure
- Physical constraints
- Noise interference
- Lighting variations
Impact on VNDA Stock Performance
Following the FDA decision, shares of Vanda Pharmaceuticals experienced a notable decline. On January 8, 2026, the stock price dropped by $1.20, translating to a 14.05% decrease, ultimately closing at $7.34 per share. This decline underscores investor concerns regarding the company's future prospects in the wake of regulatory challenges.
