New Drug Application Filing for Levoleucovorin Tablets Completed by Spectrum Pharmaceuticals, Inc.

NDA for Levoleucovorin for Injection Was Approved by the FDA on March 7th, 2008

Spectrum Plans to Launch Levoleucovorin for Injection in the Third Quarter 2008, as Soon as the FDA Approves Its Trade Name


IRVINE, Calif.--(HSMN NewsFeed)--Spectrum Pharmaceuticals, Inc. (NasdaqGM:SPPI ) today announced that it has completed its filing with the U.S. Food and Drug Administration (FDA) with the filing of an amendment to the New Drug Application (NDA) for Levoleucovorin Tablets. Levoleucovorin for Injection is indicated after high-dose methotrexate therapy in patients with osteosarcoma, and to diminish the toxicity and counteract the effects of impaired methotrexate elimination or inadvertent overdose of folic acid antagonists. LEVOleucovorin is a novel folate analog formulation and the pharmacologically active isomer of calcium leucovorin. Levoleucovorin for Injection is the only commercially available formulation comprised only of the pharmacologically active enantiomer of leucovorin (Levoleucovorin or (6S)-leucovorin).

The Oncology Drug Advisory Committee (ODAC) has already voted affirmatively that the oral formulation is safe and effective when used in the rescue of high dose methotrexate.

"Levoleucovorin Tablets is the natural product line expansion for our recently FDA approved Levoleucovorin for Injection," said Rajesh C. Shrotriya, M.D., Chairman, President, and Chief Executive Officer of Spectrum Pharmaceuticals. "If approved, the tablets will provide physicians with a new, more convenient treatment option. Furthermore, we continue to work on filing the supplemental NDA with the FDA for Levoleucovorin for Injection’s use in Colorectal Cancer with 5-fluorouracil containing regimens."

The FDA approved the NDA for Levoleucovorin for Injection on March 7, 2008. The amendment to the NDA filed provides manufacturing information and six months stability data on commercial batches, required by the FDA to complete its review of Levoleucovorin Tablets.

About Levoleucovorin for Injection

LEVOleucovorin is a novel folate analog formulation and the pharmacologically active isomer of calcium leucovorin. LEVOleucovorin is indicated after high-dose methotrexate therapy in patients with osteosarcoma, and to diminish the toxicity and counteract the effects of impaired methotrexate elimination or inadvertent overdose of folic acid antagonists. LEVOleucovorin is the only commercially available formulation comprised only of the pharmacologically active enantiomer of leucovorin (levoleucovorin or (6S)-leucovorin). Upon market launch, LEVOleucovorin will be supplied in 50mg vials of freeze-dried powder. Ex-U.S. sales of LEVOleucovorin by Wyeth, Sanofi-Aventis, and others, are approximately $200 million annually.

Important Levoleucovorin for Injection™ Safety Considerations

LEVOleucovorin is contraindicated for patients who have had previous allergic reactions attributed to folic acid or folinic acid. Due to calcium content, no more than 16mL (160mg) of Levoleucovorin for Injection solution should be injected intravenously per minute. Levoleucovorin for Injection 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 placebo-controlled study. Allergic reactions were reported in patients receiving Levoleucovorin for Injection. Vomiting (38%), stomatitis (38%) and nausea (19%) were reported in patients receiving Levoleucovorin for Injection as rescue after high dose methotrexate therapy. Levoleucovorin for Injection may counteract the antiepileptic effect of phenobarbital, phenytoin and primidone, and increase the frequency of seizures in susceptible patients.
