FDA Declines to Approve Vanda's Marketing Application for Tradipitant in Gastroparesis
Vanda Pharmaceuticals Inc. (Nasdaq: VNDA) announced that the FDA has declined to approve its New Drug Application (NDA) for tradipitant, a treatment for gastroparesis symptoms. The FDA provided a Complete Response Letter (CRL) on September 18, 2024, 185 days after the submission deadline. Vanda argues that the FDA's action fails to meet the Food Drug and Cosmetic Act requirements and disregards the evidence provided, including two placebo-controlled studies and real-world patient experiences. Despite this setback, Vanda believes tradipitant meets the substantial evidence of efficacy standard and plans to continue pursuing marketing authorization. The company will also maintain its expanded access program for gastroparesis patients and plans to submit a separate NDA for tradipitant in motion sickness prevention later this year.
Vanda Pharmaceuticals Inc. (Nasdaq: VNDA) ha annunciato che la FDA ha rifiutato di approvare la sua Domanda di Nuovo Farmaco (NDA) per il tradipitant, un trattamento per i sintomi della gastroparesi. La FDA ha fornito una Lettera di Risposta Completa (CRL) il 18 settembre 2024, 185 giorni dopo la scadenza per la presentazione. Vanda sostiene che l'azione della FDA non soddisfa i requisiti previsti dal Food Drug and Cosmetic Act e ignora le prove fornite, inclusi due studi controllati con placebo e le esperienze dei pazienti nel mondo reale. Nonostante questo contrattempo, Vanda crede che il tradipitant soddisfi lo standard di prova di efficacia sostanziale e prevede di continuare a perseguire l’autorizzazione alla commercializzazione. L'azienda manterrà anche il suo programma di accesso ampliato per i pazienti con gastroparesi e prevede di presentare una NDA separata per il tradipitant per la prevenzione della cinetosi entro la fine dell'anno.

Insights
The FDA's rejection of Vanda's NDA for tradipitant is a significant setback for the company's gastroparesis program. This decision could have substantial financial implications for Vanda, as gastroparesis represents a large, underserved market with no new FDA-approved treatments in over 40 years.
The FDA's request for additional studies with different designs suggests potential concerns about the robustness of the existing data. This could lead to increased R&D costs and delayed market entry, impacting Vanda's revenue projections and competitive positioning in the gastroparesis space.
Investors should closely monitor Vanda's next steps, including potential appeals, regulatory meetings, or new clinical trials. The company's ability to navigate this setback and advance its pipeline will be important for its long-term growth prospects.
The FDA's Complete Response Letter (CRL) for tradipitant raises significant regulatory concerns. Vanda's claim that the FDA disregarded evidence and delayed action beyond statutory timelines could potentially lead to legal challenges or formal disputes with the agency.
The FDA's reluctance to convene an advisory committee, despite Vanda's requests, is unusual for a novel treatment in an area of high unmet need. This suggests possible deeper issues with the application or data interpretation that weren't resolved during the review process.
Vanda's strategy to continue the expanded access program and pursue a separate NDA for motion sickness indicates a multi-pronged approach to maintain momentum. However, the regulatory path forward for gastroparesis remains uncertain and potentially lengthy.
The FDA's decision is a disappointment for gastroparesis patients, who have treatment options. Tradipitant's potential as a novel therapy for this debilitating condition is significant, especially given the recent association with GLP1 inhibitors, a widely used class of diabetes medications.
The FDA's request for studies with different designs raises questions about the appropriateness of current clinical trial standards for gastroparesis. This highlights the need for better alignment between regulatory requirements and clinical understanding of the disease.
The continued expanded access program is crucial, as it provides real-world data and maintains treatment access for patients. This data could potentially support future regulatory submissions or help refine study designs to address FDA concerns.
On September 18, 2024, the
Gastroparesis is a serious condition that is characterized by delayed gastric emptying and associated with severe nausea, vomiting, difficulty finishing a normal meal and other symptoms that have a significant impact in people's everyday living and functioning. Gastroparesis is often associated with diabetes but is also found in nondiabetic individuals and has recently been associated with the class of GLP1 inhibitors. There has been no effective treatment approved by the FDA in over 40 years.
Vanda's tradipitant application included evidence from two placebo-controlled studies, the results of which were published in peer review journals.1,2 The evidence of efficacy was further supported by exposure response data from a large open label study as well as the real world experience of dozens of patients treated in an expanded access program, some for several years.
The CRL was conclusory in nature, generally disregarded the evidence provided and instead suggested that Vanda conduct additional studies with a design and duration inconsistent with the advice of key experts in the field and not appropriate based on the scientific understanding and natural course of the disorder.
Furthermore, the FDA's action was delayed by more than 185 days and fails to satisfy the requirements specified by the Food Drug and Cosmetic Act (FDCA). The FDCA requires that the FDA review a new drug application and within 180 days of submission provide either an approval or an opportunity for a hearing. In this case the FDA failed to do either.
Despite this disappointing action by the FDA, Vanda believes that the tradipitant application has met the substantial evidence of efficacy standard with a favorable benefit risk profile for the treatment of patients with gastroparesis. While Vanda has repeatedly requested that the FDA convene an expert advisory committee to review the application and advise the Commissioner on the approvability of this application, the FDA has refused to do so. A number of patients currently treated with tradipitant have filed a Citizen Petition urging FDA to approve tradipitant for the treatment of gastroparesis.
Vanda will continue to pursue the marketing authorization for tradipitant and will continue to support the expanded access program that is currently serving several dozen patients with gastroparesis. Vanda encourages any patients with questions about expanded access to contact us at the following email address ExpandedAccess@vandapharma.com.
Vanda plans to submit a separate NDA for tradipitant for the prevention of vomiting in motion sickness later this year.
