Important factors that could cause actual results to differ materially from those reflected in Vanda’s forward-looking statements include, among others, Vanda’s ability to continue to grow its business; Vanda’s ability to obtain regulatory approval and execute a successful commercial launch of imsidolimab, and increase PONVORY® revenue; the FDA’s ability to complete its reviews of, and reach decisions with respect to, the NDAs for Bysanti™ and tradipitant by their respective PDUFA target action dates; Vanda’s ability to complete and submit the BLA for imsidolimab in 2025; Vanda’s ability to obtain EMA approval of the MAAs for Fanapt® and HETLIOZ® and HETLIOZ LQ®, Vanda’s ability to begin enrolling patients in the Fanapt® LAI study within the specified timeframe; Vanda’s ability to complete the Phase III clinical study for Bysanti TM for MDD and receive results in 2026; Vanda’s ability to complete the clinical trial of tradipitant for the prevention of vomiting induced by Wegovy and receive results in the third quarter of 2025; Vanda’s ability to initiate the Phase III program for VQW-765 in 2025; Vanda’s ability to enroll the CMT2S patient in the Phase I clinical study for VCA-894A by mid-2025; and Vanda’s ability to satisfy the conditions necessary to extend Bysanti TM’s patent exclusivity into the 2040s. Therefore, no assurance can be given that the results or developments anticipated by Vanda will be realized or, even if substantially realized, that they will have the expected consequences to, or effects on, Vanda.
