Allos Therapeutics Announces Folotyn Data Presentation at the 35th ESMO Congress

WESTMINSTER, Colo.--(BUSINESS WIRE)--Sep 9, 2010 - Allos Therapeutics, Inc. (Nasdaq: ALTH) today announced that results from the Phase 2b investigational trial of FOLOTYN® (pralatrexate injection) versus erlotinib in patients with Stage IIIB/IV (advanced) non-small cell lung cancer (NSCLC) will be presented at the 35th European Society of Medical Oncology (ESMO) Congress — Milan, Italy from October 8-12, 2010.

"This is the first time that Allos will have an opportunity to present the results from the Phase 2b trial of FOLOTYN in patients with advanced non-small cell lung cancer,” said Charles Morris, MB ChB, MRCP, chief medical officer at Allos Therapeutics. “We believe these are important results for the cancer community – generating data on the efficacy and safety profile for FOLOTYN in this treatment setting where there remains a high unmet need – and are pleased that the ESMO Congress has accepted these data as a late-breaking abstract to be highlighted in an oral presentation.”

The randomized, open-label, international, multi-center Phase 2b study comparing FOLOTYN versus erlotinib, marketed as TARCEVA®, enrolled 201 current or former smokers with Stage IIIB/IV (advanced) NSCLC who had received one or two previous treatments including at least one prior platinum-based chemotherapy regimen. The objective of the trial was to estimate the efficacy of FOLOTYN compared to that of erlotinib as assessed by overall survival. The primary endpoint of the trial was overall survival. Secondary endpoints included progression-free survival and response rate, both compared to erlotinib, and the safety and tolerability of FOLOTYN.

Presentation details are as follows:

About Lung Cancer

More people die each year from lung cancer than any other type of cancer – including breast, prostate, and colorectal cancers combined. In 2010, it is estimated that there will be more than 200,000 new cases of lung cancer diagnosed in the United States and over 150,000 deaths. There are primarily two types of lung cancer: NSCLC and small cell lung cancer (SCLC). NSCLC accounts for the majority of lung cancers (about 87 percent) and develops slowly – often causing few or no symptoms until very late stages. The most common subtypes of NSCLC are squamous cell carcinoma, adenocarcinoma, and large-cell undifferentiated carcinoma; squamous cell carcinomas account for 25-30 percent of all lung cancers while adenocarcinoma and large-cell undifferentiated carcinoma account for 40 percent and 10-15 percent of lung cancers, respectively. The majority of people are diagnosed with advanced stage disease and only one to five percent of people with advanced stage (IIIB/IV) NSCLC survive to five years. The most widely used therapies to date remain surgery, chemotherapy, and radiation therapy.

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 B12 to potentially reduce treatment-related hematological toxicity and mucositis.

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 ‰¥ Grade 3, omit or modify dose.

Dermatologic reactions may occur. Patients with dermatologic reactions should be monitored closely.

Adverse Reactions:

The most common adverse reactions observed 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.

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.
