• Incidence of dose-limiting toxicity, determination of maximum tolerated dose (MTD), and recommended Phase 2 dose [ Time Frame: Within 21 days of treatment administration ] [ Designated as safety issue: Yes ]
• Limited pharmacokinetics [ Time Frame: During Cycles 1 and 2; possibly at end of study, if necessary ] [ Designated as safety issue: No ]

• Tumor shrinkage according to RECIST [ Time Frame: Measured every 6 weeks (i.e., every 2 cycles) while receiving study drug ] [ Designated as safety issue: No ]
• Limited exploratory assays [ Time Frame: Variable throughout study ] [ Designated as safety issue: No ]

The purpose of this study is to determine whether MBP-426 (liposomal oxaliplatin suspension for injection) is safe and effective in the treatment of advanced or metastatic solid tumors.
