Pralatrexate Submitted to FDA
On Wednesday, March 25, 2009, Allos Therapeutics, Inc. submitted a New Drug Application to the U.S. Food and Drug Administration (FDA) for the use of Pralatrexate (PDX) for the treatment of patients with relapsed or refractory peripheral T-cell lymphoma.
Peripheral T-cell lymphomas comprise 10 to 15 percent of all non-Hodgkin lymphomas (NHL) in adults. The term peripheral T-cell lymphoma (PTCL) is based on the fact that these are tumors composed of T-cells and that the cells are mature. Most peripheral T-cell lymphomas are aggressive, with the exception of mycosis fungoides (CTCL), mentioned above with the indolent or low grade lymphomas. Peripheral T-cell lymphomas such as angioimmunoblastic T-cell lymphoma or anaplastic large cell lymphoma can arise in lymph nodes, while others like subcutaneous panniculitis-like T-cell lymphoma, nasal NK/T-cell lymphoma, or intestinal T-cell lymphoma can arise in extranodal sites. These tumors are not well understood, but they are usually aggressive and have widespread involvement at diagnosis.
