Investor Alert: Pomerantz Law Firm Investigates Vanda Pharmaceuticals Inc. - VNDA
NEW YORK, Jan. 20, 2026 (GLOBE NEWSWIRE) — Pomerantz LLP has announced the initiation of an investigation on behalf of investors in Vanda Pharmaceuticals Inc. (“Vanda” or the “Company”) (NASDAQ: VNDA). The inquiry aims to uncover whether Vanda and its executives have engaged in securities fraud or other unlawful business practices. Interested investors are encouraged to contact Danielle Peyton at newaction@pomlaw.com or call 646-581-9980, ext. 7980.
Details of the Investigation
The investigation was prompted by significant news released on January 8, 2026, when Vanda announced that it had received a decision letter from the U.S. Food and Drug Administration (FDA) regarding its supplemental New Drug Application (sNDA) for HETLIOZ® (tasimelteon), which is intended for treating jet lag disorder. The FDA concluded that the sNDA could not be approved in its current form.
- The FDA acknowledged the positive efficacy from Vanda's controlled clinical trials.
- However, the FDA determined that there was insufficient evidence to demonstrate effectiveness for jet lag disorder.
- The FDA's reasoning highlighted that the clinical trial protocols (5-hour and 8-hour bedtime shifts) did not adequately simulate actual jet travel.
- Factors such as reduced oxygen pressure, physical constraints, noise, and lighting changes were emphasized as critical elements not reflected in the trials.
Impact on Vanda Pharmaceuticals' Stock
Following the announcement, Vanda's stock price experienced a notable decline. Shares dropped by $1.20, or 14.05%, closing at $7.34 per share on January 8, 2026. This reflects a significant market reaction to the FDA's decision and potential implications for Vanda’s future revenue and growth prospects.
