A Randomized, Double-blind, Phase 3 Trial of Elesclomol (STA-4783) in Combination With Paclitaxel Versus Paclitaxel Alone for Treatment of Chemotherapy-Naïve Subjects With Stage IV Metastatic Melanoma (SYMMETRY)

"Elesclomol (STA-4783), N-malonyl-bis (N'-methyl-N'-thiobenzoylhydrazide) is a new chemical entity with a novel structure. STA-4783 induces an oxidative stress response in cells. This response is characterized by increased production of gene families that protect against different cellular stresses, including excessive heat, the presence of reactive oxygen species such as oxygen radicals, or the presence of heavy metals.

Subjects will participate in up to 2 weeks of screening during which time they will complete all screening procedures. Eligible subjects who have not received any prior cytotoxic chemotherapeutic agent for melanoma will be randomized in a 1:1 ratio to receive either STA-4783 213 mg/m2 in combination with paclitaxel 80 mg/m2 or paclitaxel 80 mg/m2 alone.

One treatment cycle will consist of weekly treatments for 3 weeks, followed by a 1-week rest period. Cycles will be repeated every 4 weeks until disease progression. Tumor assessments will be performed every 8 weeks from the date of randomization or sooner if the Investigator suspects progression has occurred based on clinical signs and symptoms. "
