, we see a clear opportunity for this drug in the first-line treatment of older patients who may not benefit from standard induction therapy," said Daniel C.

Voreloxin was generally well tolerated, with a dose-limiting toxicity of reversible oral mucositis. A maximum- tolerated weekly dose of 72 mg/m2 was established.

Sunesis also announced today that voreloxin has been accepted as the nonproprietary name for SNS-595 by the United States Adopted Names (USAN) Council, in consultation with the World Health Organization (WHO) International Nonproprietary Names Expert Committee.

The USAN Council serves health professionals in the United States by selecting simple, informative, and unique nonproprietary names for drugs by establishing logical nomenclature classifications based on pharmacological and/or chemical relationships to ensure that drug information is communicated accurately and unambiguously. The USAN Council aims for global standardization and unification of
