Sunesis Pharmaceuticals was granted orphan drug designation by the FDA for its drug candidate, voreloxin for the treatment of acute myeloid leukemia (AML). Sunesis is currently conducting two Phase 2 clinical trials of voreloxin in AML: a single-agent study, known as REVEAL-1, of voreloxin in newly diagnosed elderly AML patients unlikely to benefit from standard induction chemotherapy and a study evaluating voreloxin in combination with cytarabine in relapsed/refractory AML.

Voreloxin is a first-in-class anticancer quinolone derivative, or AQD, a class of compounds that has not been used previously for the treatment of cancer. Voreloxin both intercalates DNA and inhibits topoisomerase II, resulting in replication-dependent, site-selective DNA damage, G2 arrest and apoptosis.
