Vanda Pharmaceuticals Faces Setback with FDA on Tradipitant

FDA's Decision on Tradipitant: A Closer Look

Recently, the FDA made a pivotal decision regarding the New Drug Application (NDA) for tradipitant, developed by Vanda Pharmaceuticals Inc. This setback came as a shock, given the condition that tradipitant aims to alleviate, known as gastroparesis. The FDA sent a Complete Response Letter (CRL) to Vanda, requesting more studies and offering a conclusive analysis that left the company seeking clarity and hope for future approvals.

Understanding Gastroparesis and Its Impact

Gastroparesis, a term that translates to paralysis of the stomach, is a challenging condition for many. It essentially hampers the stomach's ability to empty its contents, causing significant discomfort and many additional symptoms. Those who suffer from it often deal with severe nausea, persistent vomiting, and great difficulty in consuming regular meals. It’s troubling that no effective treatment for this condition has been approved in over four decades, underlining the urgency for advancements in care options.

Details Surrounding the FDA's Response

The FDA’s decision involved a review of two placebo-controlled studies submitted by Vanda. The results of these studies were hoped to showcase the efficacy of tradipitant, published in reputable peer-reviewed journals. However, the FDA’s CRL seemed to overlook this evidence, suggesting that Vanda conduct further studies that may not align with current scientific understanding of gastroparesis and the natural course of its symptoms.

Regulatory Process Stumbles

Adding to Vanda’s frustrations, the FDA's response was notably delayed by more than 185 days. According to the Food, Drug, and Cosmetic Act (FDCA), a review of an NDA should ideally prompt either an approval or a chance for a hearing within 180 days. This exceeded that timeline without clarity on the reasons, leaving Vanda in a lurch regarding their next steps.

Company's Position and Future Plans

Despite the disappointing response from the FDA, Vanda Pharmaceuticals maintains that tradipitant possesses a favorable benefit-risk profile and substantial evidence to support its effectiveness for patients dealing with gastroparesis. The company has also been active in advocating for the treatment, prompting patients to file a Citizen Petition requesting the FDA to move forward with approval.

The Path Ahead for Vanda Pharmaceuticals

Looking forward, Vanda plans to persist in their efforts to secure marketing authorization for tradipitant. The company is not shying away from their mission and has plans to pursue an expanded access program to better serve patients in need. Moreover, Vanda is preparing to submit a separate NDA targeting the prevention of vomiting due to motion sickness, indicating their commitment to addressing multiple needs in patient care.

Market Reaction

The market responded to the FDA news with VNDA stock experiencing a decline, falling by 7.68% to $4.57 at the last check. This reaction highlights the financial implications of regulatory decisions while Vanda navigates this intricate landscape.
