All statements other than statements of historical fact are statements that could be deemed forward-looking statements. Forward-looking statements are based upon current expectations and assumptions that involve risks, changes in circumstances and uncertainties. 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 psychiatry portfolio and overall business; the results of Vanda’s review of foreign regulatory opportunities for imsidolmab; Vanda’s ability to identify additional indications for imsidolimab; Vanda’s ability to complete and submit to the FDA the NDA for Bysanti TM for the treatments of acute bipolar I disorder and schizophrenia in the first quarter of 2025; Vanda’s ability to complete and submit the BLA for imsidolimab for the treatment of GPP in 2025; Vanda’s ability to complete the Phase III clinical study for Bysanti TM for MDD and receive results in 2026; 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; Vanda’s ability to complete the clinical development of, obtain regulatory approval for, and successfully commercialize, Bysanti TM for the treatments of acute bipolar I disorder, schizophrenia and MDD; Vanda’s ability to satisfy the conditions necessary to extend Bysanti TM’s patent exclusivity into the 2040s; Vanda’s ability to initiate and complete the technology transfer activities and prepare the BLA and MAA for imsidolimab in the specified timeframes; and the accuracy of the estimate regarding the prevalence of PV. 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. Forward-looking statements in this press release should be evaluated together with the various risks and uncertainties that affect Vanda’s business and market, particularly those identified in the “Cautionary Note Regarding Forward-Looking Statements”, “Risk Factors” and “Management’s Discussion and Analysis of Financial Condition and Results of Operations” sections of Vanda’s most recent Annual Report on Form 10-K, as updated by Vanda’s subsequent Quarterly Reports on Form 10-Q, Current Reports on Form 8-K and other filings with the U.S. Securities and Exchange Commission, which are available atwww.sec.gov.
