研究概览
简要总结
The purpose of this study is to determine whether progression-free survival with ixabepilone is superior to that achieved with paclitaxel plus carboplatin in participants with advanced nonsmall-cell lung cancer and beta III (βIII)-tubulin-positive tumors.

结局指标
主要结局
Progression-free Survival in the Subgroup of Participants With βIII-tubulin Positive Tumors
时间窗: Randomization to disease progression or death (maximum reached: 14.39 months )
Progression-free survival is defined as the period from date of randomization to date of disease progression or death. For participants who do not progress or die at the end of the study, progression-free survival was censored at the last tumor assessment date. For those who have no on-study tumor assessment, progression-free survival was censored at the date of randomization. A tumor was considered to be beta III (βIII)-tubulin positive if 50% or more of the tumor cells had a βIII-tubulin immunohistochemistry staining intensity equal to or greater than that of the positive control.
次要结局
- Time to Response(Randomization to date of first response (PR or CR))
- Number of Participants With Death as Outcome, Drug-related Adverse Events (AEs), Serious AEs (SAEs), Drug-related SAEs, AEs Leading to Discontinuation, and Drug-related Peripheral Neuropathy(Days 1 through 21, continuously)
- Median Length of Survival in the Overall Population and in the Subgroups of Patients With βIII-tubulin Positive (β3T+) and βIII-tubulin Negative (β3T-)Tumors(Randomization to death or last known alive date, up to 31.34 months)
- Percentage of Participants With Best Response of Complete Response (CR) or Partial Response (PR)(At randomization and then every 6 weeks to date of CR, PR, or progression for 6 21-day cycles)
- Progression-free Survival in the Overall Population(Randomization to disease progression or death, assessed to 12.29 months)
- Progression-free Survival in the Subgroup of Participants With βIII-tubulin Negative Tumors(Randomization to disease progression or death (maximum reached: 12.29 months))
- Number of Participants With Hematology Laboratory Results of Grade 3 or 4(At screening and weekly during 21-day cycle)
- Number of Participants With Grade 3 or 4 Abnormalities in Liver Function and Urine Laboratory Test Results(At screening and within 72 hours of start of 21-day cycle (Cycle 2 and beyond))
