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.

IMPORTANT SAFETY INFORMATION Warnings and Precautions FOLOTYN may suppress bone marrow function, manifested by thrombocytopenia, neutropenia, and anemia. Monitor blood counts and omit or modify dose for hematologic toxicities. Mucositis may occur. If ≥Grade 2 mucositis is observed, omit or modify dose. Patients should be instructed to take folic acid and receive vitamin B 12 to potentially reduce treatment-related hematological toxicity and mucositis. Fatal dermatologic reactions may occur. Dermatologic reactions may be progressive and increase in severity with further treatment. Patients with dermatologic reactions should be monitored closely, and if severe, FOLOTYN should be withheld or discontinued.
