Various statements to be made during the Earnings Call are “forward-looking statements” under the securities laws, including, but not limited to, statements regarding Vanda’s commercial products, plans and opportunities, as well as statements about Vanda’s products in development and the related clinical development and regulatory timelines and commercial potential for such products. Words such as, but not limited to, “believe,” “expect,” “anticipate,” “estimate,” “intend,” “plan,” “project,” “target,” “goal,” “likely,” “will,” “would,” and “could,” or the negative of these terms and similar expressions or words, identify forward-looking statements. 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 assumptions regarding the strength of its business in the U.S. and Vanda’s ability to complete the clinical development of, and obtain regulatory approval for, the products in its pipeline. Therefore, no assurance can be given that the actual 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 made during the Earnings Call 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 at www.sec.gov.
All written and verbal forward-looking statements attributable to Vanda or any person acting on its behalf are expressly qualified in their entirety by the cautionary statements contained or referred to herein. The information contained in this Current Report on Form 8-K is intended to be considered in the context of Vanda’s filings with the SEC and other public announcements that Vanda makes, by press release or otherwise, from time to time.

WASHINGTON – May 8, 2024 – Vanda Pharmaceuticals Inc. (Vanda) (Nasdaq: VNDA) today announced financial and operational results for the first quarter ended March 31, 2024.
“We are very proud of our accomplishments in the first quarter of 2024, which were achieved with a small but efficient organization that is enthusiastic to continue developing and commercializing treatments for people who need them,” said Mihael H. Polymeropoulos, M.D., Vanda’s President, CEO and Chairman of the Board. “We expect several significant milestones in the coming months, including the launch of Fanapt in acute bipolar I disorder, the launch of Ponvory in multiple sclerosis, the potential approval of tradipitant in gastroparesis, the phase III results of tradipitant in motion sickness, the upcoming NDA filings of milsaperidone in psychiatric disorders and of tradipitant in motion sickness and the initiation of clinical programs in depression, psoriasis, ulcerative colitis and pediatric insomnia. We are confident that our robust revenue, strong cash position and efficient operations position us well for significant growth and value creation in the years to come.”
Financial Highlights
•Total net product sales from Fanapt®, HETLIOZ® and PONVORY® were $47.5 million in the first quarter of 2024, a 24% decrease compared to $62.5 million in the first quarter of 2023, and a 5% increase compared to $45.3 million in the fourth quarter of 2023.
•Fanapt® net product sales were $20.6 million in the first quarter of 2024, a 10% decrease compared to $22.9 million in the first quarter of 2023, and a 9% decrease compared to $22.6 million in the fourth quarter of 2023.
•HETLIOZ® net product sales were $20.1 million in the first quarter of 2024, a 49% decrease compared to $39.6 million in the first quarter of 2023, and a 5% decrease compared to $21.1 million in the fourth quarter of 2023. The decrease relative to the first quarter of 2023 was the result of continued generic competition in the U.S.
•PONVORY® net product sales were $6.8 million in the first quarter of 2024. The acquisition of PONVORY® from Actelion Pharmaceuticals Ltd. (Janssen), a Johnson & Johnson Company, was completed on December 7, 2023.
•Net loss was $4.1 million in the first quarter of 2024, compared to net income of $3.3 million in the first quarter of 2023, and net loss of $2.4 million in the fourth quarter of 2023.
•Cash, cash equivalents and marketable securities (Cash) was $394.1 million as of March 31, 2024, representing an increase to Cash of $5.9 million compared to December 31, 2023.


Key Operational Highlights
Psychiatry Portfolio
•Fanapt® (iloperidone): Vanda announced in April 2024 that the U.S. Food and Drug Administration (FDA) approved Fanapt® as a first line treatment of acute bipolar I disorder in adults. This approval of Fanapt® for acute bipolar I disorder significantly expands the addressable patient population. Patent exclusivity is expected to last at least through late 2027. Vanda is initiating a host of commercial activities, including the expansion of its existing sales force, a prescriber awareness program and a comprehensive marketing program.
•Milsaperidone: Vanda expects to submit a New Drug Application (NDA) for milsaperidone (also known as VHX-896 and P-88), the active metabolite of Fanapt®, in schizophrenia and acute bipolar I disorder to the FDA in early-2025. If approved, there are pending patent applications that, if issued, could extend exclusivity into the 2040s.
•Fanapt® LAI: Vanda expects to initiate a Phase III program for the long acting injectable (LAI) formulation of Fanapt® by the end of 2024. Fanapt® LAI could reach the U.S. market after 2026 and there are pending patent applications that, if issued, could extend exclusivity into the 2040s.
•Vanda is currently planning clinical programs to test the efficacy of Fanapt® and milsaperidone in the treatment of depressive symptoms which, if successful, will significantly expand the addressable patient population.
HETLIOZ® (tasimelteon)
•Vanda is currently planning to initiate a HETLIOZ LQ® program in pediatric insomnia. Although exact estimates of prevalence of insomnia in children are difficult to quantify, it is estimated that 20-40% of children experience significant sleep problems.1,2 There are currently no approved treatments for pediatric insomnia. If ultimately approved for marketing, the addressable patient population for HETLIOZ LQ® would be significantly expanded and market exclusivity would be expected to last into the 2040s.
•Vanda announced in March 2024 that it received a complete response letter (CRL) from the FDA related to the supplemental New Drug Application (sNDA) for HETLIOZ® in the treatment of insomnia. Vanda is reviewing the CRL and evaluating its next steps. In addition to insomnia, Vanda continues to pursue FDA approval of HETLIOZ® in the treatment of jet lag disorder where the final agency rejection of our application is being challenged in the U.S. Court of Appeals for the D.C. Circuit.
•Vanda announced in April 2024 that the U.S. Supreme Court denied its petition for a writ of certiorari to review the decision of the U.S. Court of Appeals for the Federal Circuit in Vanda’s HETLIOZ® Abbreviated New Drug Application litigation against Teva Pharmaceuticals USA, Inc. (Teva), Apotex Inc. and Apotex Corp (together, Apotex). The lower court decision held that certain claims of Vanda’s U.S. Patent Nos. RE46,604; 9,730,910; 10,149,829; and 10,376,487 were invalid. Vanda’s suit asserting U.S. Patent No. 11,285,129 will be infringed by Teva’s and Apotex’s generic versions of HETLIOZ® is currently pending in the U.S. District Court for the District of Delaware.
PONVORY® (ponesimod)
•Vanda expects to complete the transition of PONVORY® from Janssen and commercially launch the product for multiple sclerosis in the third quarter of 2024. Vanda is initiating a host of commercial activities including the creation of a specialty sales force, a prescriber awareness program and a comprehensive marketing program. Currently approved as a once-a-day oral treatment for people with multiple sclerosis, PONVORY® has a differentiated profile from other drugs in the class with high specificity and rapid reversibility, making for a versatile use to address the needs of people with multiple sclerosis and exclusivity is expected to last into the 2040s.
•Positive results from a Phase II clinical study for PONVORY® in the treatment of psoriasis were previously published in Lancet where PONVORY® demonstrated significant effects in both induction and maintenance of response.3 Vanda expects to file an Investigational New Drug (IND) application with the FDA for PONVORY® in the treatment of psoriasis. Vanda expects to initiate a Phase III study for PONVORY® in the treatment of psoriasis by the end of 2024. If ultimately approved for marketing, PONVORY® would be the first oral sphingosine-1-phosphate (S1P) analog approved for the treatment of psoriasis and would significantly expand the addressable patient population of PONVORY®, with over 8 million people diagnosed with psoriasis in the U.S.4
•Vanda expects to file an IND application with the FDA for PONVORY® in the treatment of ulcerative colitis. Vanda expects to initiate a Phase III study for PONVORY® in the treatment of ulcerative colitis by the end of 2024. If


ultimately approved for marketing, PONVORY® would follow other oral sphingosine-1-phosphate (S1P) analogs approved for the treatment of ulcerative colitis and would significantly expand the addressable patient population of PONVORY®, with an estimated prevalence in the U.S. of approximately 2 million individuals.5
Tradipitant
•The NDA for tradipitant for the treatment of symptoms of gastroparesis is under review by the FDA with a PDUFA target action date of September 18, 2024. Gastroparesis is a significant unmet medical need with the last treatment option approved over 40 years ago and an estimated prevalence in the U.S. of over 6 million individuals.6
•The second Phase III clinical study of tradipitant in the treatment of motion sickness is fully enrolled and results are expected in the second quarter of 2024. The efficacy of tradipitant in the treatment of motion sickness has previously been demonstrated in two clinical studies in which tradipitant was effective in preventing vomiting associated with motion. Vanda expects to submit an NDA for the treatment of motion sickness to the FDA in the fourth quarter of 2024. An eventual NDA approval of tradipitant in the treatment of motion sickness would significantly expand the addressable patient population, with approximately 30% of the U.S. population reported to suffer from motion sickness under ordinary travel conditions that include sea, air and land.7
Early-Stage Programs
•The Phase II study of VSJ-110 for the treatment of dry eye is ongoing and more than 50% enrolled.
•The Phase I clinical study for VCA-894A in the treatment of a patient with Charcot-Marie-Tooth disease, axonal, type 2S (CMT2S), an inherited peripheral neuropathy for which there is no available treatment, expects to enroll the patient in mid-2024.
•The Phase I clinical study of VTR-297 for the treatment of onychomycosis, a fungal infection of the nail, was initiated in April 2024.
•VQW-765, an alpha-7 nicotinic acetylcholine receptor partial agonist, is currently in clinical development for treatment of acute performance anxiety in social situations.
GAAP Financial Results
Net loss was $4.1 million in the first quarter of 2024 compared to net income of $3.3 million in the first quarter of 2023. Diluted net loss per share was $0.07 in the first quarter of 2024 compared to diluted net income per share of $0.06 in the first quarter of 2023.
2024 Financial Guidance
Given continuing uncertainties surrounding the U.S. market for HETLIOZ® for the treatment of Non-24 as a result of continued generic competition in the U.S. and the upcoming commercial launches for Fanapt® in acute bipolar I disorder and PONVORY® in multiple sclerosis, Vanda is unable to provide 2024 financial guidance at this time.
