Spectrum Pharmaceuticals Files Supplemental New Drug Application with FDA for FUSILEV(TM) in Colorectal Cancer

IRVINE, Calif.--(HSMN NewsFeed)--Spectrum Pharmaceuticals, Inc., (NasdaqGM:SPPI ) today announced that it has filed with the FDA the supplemental NDA for FUSILEV™ (levoleucovorin) for injection in combination with 5-FU containing regimens in advanced metastatic colorectal cancer. FUSILEV is the only commercially available formulation comprised only of the pharmacologically active isomer of leucovorin.

“Ninety percent of the more than 500 million milligrams of leucovorin used in the United States is for colorectal cancer,” said Rajesh C. Shrotriya, M.D., Chairman, Chief Executive Officer, and President of Spectrum Pharmaceuticals. “Assuming the FDA accepts the filing and completes the standard 10-month review cycle, we would expect a complete response late in the third or early in the fourth quarter of 2009. We continue to expect our sales, under the currently approved indications, to ramp up slowly until the full range of indications and formulations are approved.”

Earlier this year, the Company completed its filing of an amendment to the New Drug Application (NDA) for FUSILEV™ Tablets. The Oncologic Drugs Advisory Committee (ODAC) has already voted affirmatively that the oral formulation is safe and effective when used in the rescue of high dose Methotrexate.

About FUSILEV (levoleucovorin) for injection

FUSILEV, a novel folate analog, is available in 50-mg vials of freeze-dried powder. It is the pharmacologically active isomer of leucovorin. FUSILEV rescue is indicated after high-dose Methotrexate therapy in osteosarcoma. FUSILEV is also indicated to diminish the toxicity and counteract the effects of impaired Methotrexate elimination and of inadvertent overdosage of folic acid antagonists. FUSILEV (levoleucovorin or (6S)-leucovorin) is the only commercially available formulation comprised only of the pharmacologically active isomer of leucovorin.

Important FUSILEV (levoleucovorin) for injection Safety Considerations

FUSILEV is contraindicated for patients who have had previous allergic reactions attributed to folic acid or folinic acid. Due to calcium content, no more than 16-mL (160-mg) of levoleucovorin solution should be injected intravenously per minute. FUSILEV enhances the toxicity of fluorouracil. Concomitant use of d,l-leucovorin with trimethoprim-sulfamethoxazole for pneumocystis carinii pneumonia in HIV patients was associated with increased rates of treatment failure in a placebo-controlled study. Allergic reactions were reported in patients receiving FUSILEV. Vomiting (38%), stomatitis (38%) and nausea (19%) were reported in patients receiving FUSILEV as rescue after high dose Methotrexate therapy. FUSILEV may counteract the antiepileptic effect of phenobarbital, phenytoin and primidone, and increase the frequency of seizures in susceptible patients.
