Spectrum Pharmaceuticals (NasdaqGS: SPPI), a biotechnology Company with fully integrated commercial and drug development operations with a primary focus in Hematology and Oncology, announced two oral presentations of data on FOLOTYN and research progress for the treatment of Peripheral T-Cell Lymphoma (PTCL) at the 59th American Society of Hematology (ASH).

Abstract #818: Pralatrexate in Combination with Cyclophosphamide, Doxorubicin, Vincristine, and Prednisone (CHOP) in Previously Untreated Patients with Peripheral T-Cell Lymphoma (PTCL): A Phase 1 Dose-Escalation Study

In this study presented by Dr. Andrei Shustov from Division of Hematology, University of Washington, a total of 31 patients have been enrolled (19 in Part 1; 12 in Part 2). MTD was not reached and pralatrexate dose of 30 mg/m2 in combination with CHOP was selected for Part 2 of the study as predefined by the protocol. The majority of patients were male, white, with the median age of 57.7 years (range, 18-78) at the time of enrollment. PTCL diagnoses included: anaplastic large cell lymphoma, anaplastic lymphomakinase-negative (ALCL, ALK-, n=5), peripheral T-cell lymphoma, not-otherwise specified (PTCL-NOS, n=18), and angioimmunoblastic T-cell lymphoma (AITL, n=5). Fol-CHOP was generally well tolerated with median RDI of 98%. Grade 3/4 adverse events included anemia (23%), neutropenia (23%), fatigue (13%), and vomiting (13%), as well as febrile neutropenia, nausea, and mucositis each in 10% of the patients. SAEs were observed in 13 patients, treatment related SAEs were anemia, febrile neutropenia, dehydration, mucositis, and nausea. Six patients withdrew from study before the completion of the follow-up, and dose reduction or dose delay occurred in four patients. In the 29 patients evaluable for response, the investigator assessed objective response (OR) and complete response (CR) rates were 90% and 66%, respectively.

Abstract #342: The Role of Upfront Hematopoietic Stem Cell Transplantation (HSCT) in Peripheral T-Cell Lymphoma (PTCL) Patients in Complete Remission (CR) with a Special Focus on Nodal PTCL: Report from the Comprehensive Oncology Measures for Peripheral T-Cell Lymphoma Treatment (COMPLETE), a Prospective Multicenter Cohort Study

In this study, presented by Dr. Steven Park from Levine Cancer Institute, a total of 499 PTCL patients were enrolled in COMPLETE over 4 years. Two hundred thirteen patients achieved a CR following frontline therapy and had the required locked records for the analysis with a median follow-up of 2.9 years (Range 1.9-4.0). One hundred forty nine (70%) of these received induction therapy without HSCT consolidation and 64 (30%) underwent either autologous (n = 49) or allogeneic (n = 15) HSCT. This is the first report from the largest prospective PTCL database in the U.S. to date to examine the role of HSCT in PTCL patients who are in first CR. Our data demonstrate potential survival advantages of upfront HSCT in patients with nodal PTCL who achieve CR. However, the results should be interpreted with caution given a relatively short median follow up as well as the non-randomized study design. The role of HSCT among various groups of PTCL patients in first CR should further be evaluated in randomized controlled trials.

“We are honored that two oral presentations and multiple abstracts were presented at the 59th ASH Meeting,” said Rajesh C. Shrotriya, MD, Chairman and Chief Executive Officer of Spectrum Pharmaceuticals. “FOLOTYN was the first drug approved for the treatment of relapsed or refractory PTCL. PTCL is an aggressive disease with a poor prognosis and we are excited that FOLOTYN has the potential to improve outcome for PTCL patients.”

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 patients in the U.S. since October 2009. An updated analysis of data from PROPEL, the pivotal study of FOLOTYN in patients with relapsed or refractory PTCL, was published in the March 20, 2011 issue of the Journal of Clinical Oncology.

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.

Adverse Reactions

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.

Drug Interactions

Co-administration of drugs subject to renal clearance (e.g., probenecid, NSAIDs, and trimethoprim/sulfamethoxazole) may result in delayed renal clearance.
