Vanda provides update to Hetlioz ANDA litigation appeal

On Dec. 14, 2022, Vanda appealed the Dec. 13 decision of the United States District Court for the District of Delaware in the Hetlioz ANDA litigation to the United States Court of Appeals for the Federal Circuit and requested an injunction prohibiting market entry by Teva and Apotex while the appeal is pending.

The court on Dec. 16, 2022, granted a temporary injunction to prohibit market entry by Teva and Aptex until at least Jan. 6, 2023, while the Court considers Vanda's pending motion for an injunction that would extend until the Court decides the appeal.
