Spectrum Pharmaceuticals Highlights Survival Advantage in a Case Match Control Analysis of the PROPEL Study with FOLOTYN® (pralatrexate injection) at the 58th Annual Meeting of the American Society of Hematology (ASH)
Abstract #4149: Case Match Control Analysis of Propel Reveals Survival Advantage for Patients with Relapsed/Refractory (R/R) Peripheral T-Cell Lymphoma (PTCL) Treated with Pralatrexate
In this retrospective, observational study, 80 patients out of 109 treated on the PROPEL study were successfully matched 1:1 with the control population. A highly significant difference in the Overall Survival between the control population and the pralatrexate group was observed. The overall survival observed in the control population was 4.04 months (95% CI 2.60, 6.01) which was consistent with historical controls, while the median OS in for pralatrexate treated cohort was 14.78 months (95% CI 10.61-22.31). The most common adverse reactions from the PROPEL study were mucositis (70%), thrombocytopenia (41%), nausea (40%), and fatigue (36%). The most common serious adverse events were pyrexia, mucositis, sepsis, febrile neutropenia, dehydration, dyspnea, and thrombocytopenia. See below for Important Safety Information.
"In this case match controlled study, the overall survival observed in
the pralatrexate group was over three-fold higher than a case matched
control group," said
"We are honored to present this important data at the 58th
ASH Meeting," said

FOLOTYN, (pralatrexate injection), a folate analogue metabolic
inhibitor, was discovered by Memorial Sloan-Kettering Cancer Center, 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

Important FOLOTYN® 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 greater-than or equal to Grade 2 mucositis is observed, omit or modify dose. Patients should be instructed to take folic acid and receive vitamin B12 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. Tumor lysis syndrome may occur. Monitor patients and treat if needed.
FOLOTYN can cause fetal harm. Women should avoid becoming pregnant while being treated with FOLOTYN and pregnant women should be informed of the potential harm to the fetus.
Use caution and monitor patients when administering FOLOTYN to patients with moderate to severe renal function impairment.
Elevated liver function test abnormalities may occur and require monitoring. If liver function test abnormalities are greater-than or equal to Grade 3, omit or modify dose.
The most common adverse reactions were mucositis (70%), thrombocytopenia (41%), nausea (40%), and fatigue (36%). The most common serious adverse events are pyrexia, mucositis, sepsis, febrile neutropenia, dehydration, dyspnea, and thrombocytopenia.
Use in Specific Patient Population
Nursing mothers should be advised to discontinue nursing or the drug, taking into consideration the importance of the drug to the mother.
Co-administration of drugs subject to renal clearance (e.g., probenecid, NSAIDs, and trimethoprim/sulfamethoxazole) may result in delayed renal clearance.
