FOLOTYN, a folate analogue metabolic inhibitor, was discovered by Sloan-Kettering Institute for Cancer Research, SRI International and Southern Research Institute and developed by Allos Therapeutics. In September 2009, the U.S. Food and Drug Administration (FDA) granted accelerated approval for FOLOTYN for use as a single agent for the treatment of patients with relapsed or refractory PTCL. This indication is based on overall response rate. Clinical benefit such as improvement in progression-free survival or overall survival has not been demonstrated. FOLOTYN has been available to patients in the U.S. since October 2009.
About Peripheral T-Cell LymphomaPeripheral T-cell lymphomas are a biologically diverse group of aggressive, mature T and NK (natural killer) cell non-Hodgkin lymphomas with similar outcomes, which include PTCL-NOS (PTCL not otherwise specified), AITL (angioimmunoblastic T-cell lymphoma), and ALCL (anaplastic large-cell lymphoma). 1 The prognosis for patients with PTCL is generally poor for most subtypes. 2 T-cell lymphomas account for approximately 10% to 15% of all cases of non-Hodgkin lymphomas (NHL). 1-3 The majority of patients ultimately have refractory disease to a variety of agents, including multi-agent chemotherapy with CHOP (cyclophosphamide, doxorubicin, vincristine, and prednisone) or CHOP-like regimens. The 5-year overall survival rate in these patients is 25% to 40%, depending on sub-type. 4-5 About Conditional Marketing Authorisation A conditional marketing authorisation is granted to a medicinal product with a positive benefit/risk assessment that fulfils an unmet medical need when the benefit to public health of immediate availability outweighs the risk inherent in the fact that additional data are still required. A conditional marketing authorisation is renewable annually. As part of the conditions of a conditional marketing authorisation for FOLOTYN, further data would be required.
