• Hemoglobin ≥ 9 gm/dl
• Serum creatinine ≤ 1.5 x ULN
• Calculated creatinine clearance ≥ 60 mL/min

• ALT ≤ 2.5 x ULN; -OR- ALT ≤ 5 x ULN in the presence of known liver metastases
• Total bilirubin ≤ 1.5 x ULN
• Potassium within normal range or correctable with supplements
• Magnesium within normal range or correctable with supplements
• Corrected serum calcium within normal range, or correctable with supplements
• Not pregnant or breastfeeding. Female subjects of childbearing age must have a negative serumpregnancy test at study entry
• Women of childbearing potential and men must agree to use adequate contraception prior to study entry and for the duration of study participation and for 6 months following last study drug administration
• Agreement to provide blood samples for pharmacodynamic studies utilizing Peripheral Blood Mononuclear Cells (PMBCs) as outlined in protocol
• At least one site of measurable disease as defined by at least 1 cm in greatest dimension. This site must be different from the sites to be used for biopsy. No prior radiation therapy or directed ablation to the site of measureable disease
• Able to understand and willing to sign a written informed consent document
• Willing and able to comply with scheduled visits, treatment plans, laboratory tests, and other study procedures
• No chemotherapy within 4 weeks (6 weeks for nitrosoureas or mitomycin C) prior to study entry
• No radiotherapy within 4 weeks prior to study entry
• Subject has recovered from adverse events due to agents administered more than 4 weeks earlier
• No tyrosine kinase inhibitor within 14 days prior to study entry
• No major surgery within 4 weeks prior to first dose of STA-9090
• No minor surgery within 7 days of first dose of STA-9090
• No history of or current coronary artery disease, myocardial infarction, angina pectoris, angioplasty

• Not receiving any other investigational agents
• No poor venous access for study drug administration unless subject can use silicone based catheters
• No history of brain metastases or of leptomeningeal involvement
• No history of severe allergic reactions or hypersensitivity reactions attributed to compounds of similar chemical or biologic composition to STA-9090 (e.g. olyethylene glycol \[PEG\] 300 or Polysorbate 80)
• Baseline QTc ≤ 470 msec
• No previous history of QT prolongation while taking other medications
• Ventricular ejection fraction (EF) \> 55%
• No treatment with chronic immunosuppressants
• No melanoma of ocular primary
• No prior treatment with hsp90 inhibitor
• No uncontrolled intercurrent illness including, but not limited to ongoing or active infection, ventricular arrhythmia, or psychiatric illness/social situations that would limit compliance with study requirements
• No other medications, or severe acute/chronic medical of psychiatric conditions or laboratory abnormality that may increase the risk associated with the study participation or study drug administration, or may interfere with the interpretation of study results, and in the judgment of the investigator would make the subject inappropriate for entry into the study
• No HIV-positive subject on combination antiretroviral therapy
• No more than 3 prior systemic therapies for unresectable stage III or stage IV melanoma
