Primary Outcome Measures

Name	Time	Method
Maximum Tolerated Dose (MTD) and Recommended Phase 2 Dose of Carboplatin in Combination With Ixabepilone, 32 mg/m^2	Days 1 through 21 (Cycle 1)	The MTD was defined as the highest dose evaluated for which less than one sixth of patients experience a DLT in Cycle 1. The recommended phase 2 dose is the MTD defined in Cycle 1, with consideration given to chronic cumulative toxicity occurring at later cycles.
Number of Participants With Dose-limiting Toxicity (DLT)	Days 1 through 21 (Cycle 1)	DLT is defined as any of the following: Common Terminology Criteria (CTC), Version 3, Grade(Gr) 4 neutropenia (absolute neutrophil count \<500 cells/mm\^3) for at least 5 days or febrile neutropenia; Gr 4 thrombocytopenia (\<25,000 cells/mm\^3 or bleeding needing platelet transfusion); Gr 3 or 4 nausea, vomiting, or diarrhea, despite medical intervention; any other drug-related Gr 3 or 4 nonhematologic toxicity, except Gr 3 injection site reaction, fatigue/asthenia, transient arthralgia/myalgia, or transient electrolytes abnormal. Gr 1=Mild; Gr 2=Moderate; Gr 3=Severe; Gr 4=Life-threatening.

Secondary Outcome Measures

Name	Time	Method
Number of Participants With Grade 3 or Greater Treatment-related AEs	Days 1 through 21 (Cycle 1)	An AE is defined as any new untoward medical occurrence or worsening of a preexisting medical condition that does not necessarily have a causal relationship with treatment. AEs graded according to CTC, Version 3.0. Gr 1=Mild; Gr 2=Moderate; Gr 3=Severe; Gr 4=Life-threatening. Treatment-related comprises certainly, probably, and possibly related and of unknown relationship to study drug.
Number of Participants With Abnormalities in Urine Testing Results by Worst CTC Grade	At screening and Days 8 and 15 of Cycle 1 (21 days)	Toxicities graded according to CTC, Version 3. Protein Gr 1: \<1.0 g/24 hrs (1+); Gr 2: 1.0 to 3.4 g/24 hrs (2+ to 3+ ); Gr 3: \>=3.5 g/24 hrs (4+); Gr 4: Nephrotic syndrome. Note: + = qualitative measure of urine chemistry.
