HENDERSON, Nev.--(BUSINESS WIRE)--
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."

About FOLOTYN®
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.
