Vanda Pharmaceuticals Raises Concerns on FDA Drug Review Process
Vanda Pharmaceuticals Inc. (NASDAQ: VNDA) has recently communicated pressing concerns regarding the FDA's review of tradipitant for gastroparesis treatment. This communication reflects on the agency's decision-making process and its implications for public health.
Background on Tradipitant's NDA Submission
Vanda has been seeking FDA approval for tradipitant to address the significant unmet needs of patients suffering from gastroparesis, a challenging gastrointestinal condition. The company had anticipated a favorable response to their New Drug Application (NDA) but was met with a Complete Response Letter (CRL) on September 18, which cited reasons for not approving the application.
Concerns Over FDA’s Decision-Making
In a recent letter addressed to FDA Commissioner Dr. Robert M. Califf, Vanda expressed concerns about several aspects of the agency's operations, particularly regarding transparency and accountability. Vanda's CEO, Mihael H. Polymeropoulos, emphasized that the FDA's current stance—where decisions made by civil servants may go unchallenged—creates an opaque environment that is concerning for both the public and the companies involved in vital drug development.
The Letter to the FDA Commissioner
Vanda's correspondence with the FDA highlighted a perceived inconsistency in the agency's review processes. The letter pointed out that a response received on the CRL demonstrated a troubling disregard for scientific principles and the substantial evidence Vanda had presented in support of tradipitant. The company felt the lack of engagement from the FDA, particularly the absence of acknowledgment to their previous communication, indicated dysfunction within the agency.
Need for Advisory Committees
An additional point of contention in Vanda's communication was the FDA's refusal to convene an Advisory Committee to discuss the tradipitant application. This was framed against a backdrop of declining occurrences of such meetings, significantly reducing avenues for public and expert input into drug approvals. The lack of these critical discussions raises questions about the rigor and credibility of the review process.
Implications for Vanda and Patients
The challenges presented by the FDA’s review process affect not only Vanda Pharmaceuticals but also countless patients awaiting effective treatments for gastroparesis. Tradipitant promises to offer a much-needed solution, and delays resulting from bureaucratic hurdles can significantly impact patient health outcomes. The letter indicates Vanda's commitment to advocating for their product's approval while pressing the FDA to uphold high standards of accountability.
Looking Forward
Although there are indications that changes in FDA leadership may occur soon, Vanda stresses the importance of using this period to enhance the FDA's policies and procedures. They hope that this dialogue will pave the way for future developments that align regulatory processes with the foundational scientific evidence that guides drug approval.
