Aggressive Systemic Mastocytosis (ASM): Metanib is indicated for the treatment of adult patients with aggressive systemic mastocytosis without the D816V c-Kit mutati on as determined with an FDA-approved test.

Hypereosinophilic Syndrome (HES) and/or Chronic Eosinophilic Leukemia (CEL): Metanib is indicated for the treatment of adult patients with hypereosinophilic syndrome and/or chronic eosinophilic leukemia who have the FIP1L1-PDGFR a fusion kinase (mutational analysis or FISH demonstration of CHIC2 allele deletion) and for patients with HES and/or CEL who are FIP1L1-PDGFR a fusion kinase negative or unknown.

Dermatofibrosarcoma Protuberans (DFSP): Metanib is indicated for the treatment of adult patients with unresectable, recurrent and/or metastatic dermatofibrosarcoma pr otuberans.

Kit+ Gastrointestinal Stromal Tumors (GIST): Metanib is indicated for the treatment of patients with Kit (CD117) positive unresectable and/or metastatic malignant gastrointestinal stromal tumors.

Adjuvant Treatment of GIST: Metanib is indicated for the adjuvant treatment of adult patients following complete gross resection of Kit (CD117) positive GIST.

Dosage and Administration: The prescribed dose should be administered orally, with a meal and a large glass of water. Doses of 400 mg or 600 mg should be administered once daily, whereas a dose of 800 mg should be administered as 400 mg twice a day. For patients unable to swallow the film-coated tablets, the tablets may be dispersed in a glass of water or apple juice. The required number of tablets should be placed in the appropriate volume of beverage (approximately 50 ml for a 100 mg tablet, and 200 ml for a 400 mg tablet) and stirred with a spoon. The suspension should be administered immediately after complete disintegration of the tablet(s). For daily dosing of 800 mg and above, dosing should be accomplished using the 400 mg tablet to reduce exposure to iron. Treatment may be continued as long as there is no evidence of progressive disease or unacceptable toxicity.

Adult Patients with Ph+ CML CP, AP, or BC: The recommended dose of Metanib is 400 mg/day for adult patients in chronic phase CML and 600 mg/day for adult patients in accelerated phase or blast crisis. In CML, a dose increase from 400 mg to 600 mg in adult patients with chronic phase disease, or from 600 mg to 800 mg (given as 400 mg twice daily) in adult patients in accelerated phase or blast crisis may be considered in the absence of severe adverse drug reaction and severe non-leukemia related neutropenia or thrombocytopenia in the following circumstances: disease progression (at any time), failure to achieve a satisfactory hematologic response after at least 3 months of treatment, failure to achieve a cytogenetic response after 6 to 12 months of treatment, or loss of a previously achieved hematologic or cyto genetic response.

Pediatric Patients with Ph+ CML CP: The recommended dose of Metanib for children with newly diagnosed Ph+ CML is 340 mg/m2/day (not to exceed 600 mg). Metanib treatment can be given as a once daily dose or the daily dose may be split into two–one portion dosed in the morning and one portion in the evening.
