DUBLIN -- Jazz Pharmaceuticals plc (Nasdaq: JAZZ) today announced the initiation of a rolling submission of a New Drug Application (NDA) to the United States (U.S.) Food and Drug Administration (FDA) for defibrotide for the treatment of severe hepatic veno-occlusive disease (VOD) in patients undergoing hematopoietic stem-cell transplantation (HSCT) therapy. Defibrotide has been granted Fast Track Designation to treat severe VOD by the FDA.
"Our start of the NDA submission for defibrotide marks an important step forward in our efforts to provide a treatment option for patients in the U.S. who develop this rare, life-threatening complication of HSCT," said Jeffrey Tobias, M.D., executive vice president and chief medical officer of Jazz Pharmaceuticals. "We expect to complete the submission of the NDA in the first half of 2015, at which time we will be requesting a Priority Review of the application, and we will continue to work closely with the FDA as we seek approval of the NDA. As part of our commitment to ensure that eligible patients have access to defibrotide as we pursue U.S. approval, we will continue to provide patients access to defibrotide through an expanded access treatment protocol that is open under an ongoing investigational new drug application in the U.S."
The Fast Track Designation is designed to facilitate the development and expedite the review of drugs that treat serious, life-threatening conditions and that address unmet medical needs. The Fast Track process allows a company to submit individual sections of its NDA for review by the FDA as they are completed rather than waiting until the entire application is complete before it can be submitted and reviewed.
Earlier this year, Jazz Pharmaceuticals acquired the rights to defibrotide in the U.S. and other markets in North America, South America and Central America. Jazz Pharmaceuticals markets defibrotide in Europe under the name Defitelio®▼ (defibrotide). Defitelio is the first and only licensed product in Europe for the treatment of severe hepatic VOD in patients over one month of age undergoing HSCT therapy.
Veno-occlusive disease (VOD) is an early complication in patients undergoing HSCT therapy. In its severe form, VOD can be life-threatening and is associated with multi-organ failure; it is fatal in over 80% of patients.1,2 HSCTs are performed with curative intent in patients with hematological malignancies, selected solid tumors and some non-malignant disorders, such as serious hemoglobinopathies.3,4 In the U.S., defibrotide was granted Orphan Drug Designation to treat and prevent VOD by the FDA in May 2003.
In October 2013, the European Commission granted marketing authorization under exceptional circumstances for Defitelio®▼ (defibrotide) for the treatment of severe hepatic VOD in patients undergoing HSCT therapy. It is indicated in patients over one month of age. Defitelio is not indicated in patients with hypersensitivity to defibrotide or any of its excipients or with concomitant use of thrombolytic therapy.
