A Trial Comparing Safety and Efficacy of Carboplatin and Paclitaxel Plus or Minus Sorafenib (BAY43-9006) in Chemonaive Patients With Stage IIIB-IV Non-Small Cell Lung Cancer (NSCLC)

Progression free survival (PFS) is the time (days) from date of randomization to date of first observed disease progression (radiological or clinical, whichever was earlier) or death due to any cause, if death occurred before progression was documented. Since the study was terminated early and 89% of subjects' data were censored, only the number of PFS events (Failed \[progressed or died before progression\]) is reported, not the usual measure number of days.

Time frame: Up to 5 months after randomization of the first patient

Population: It was intended to include all randomized subjects (the intent to treat (ITT) population) in the analysis. Since 89% of subjects were censored, PFS could not be calculated. The number of subjects who Failed (progressed or died before progression) or were Censored are reported.

Complete response (CR): Disappearance of all target lesions (TL). Partial response (PR): At least 30% decrease in sum of the largest diameter (LD) of TLs, taking baseline sum as reference. Stable disease (SD): No change in tumor size. Progressive disease (PD): At least a 20% increase in the sum of the LD of TLs, taking as reference the smallest sum LD recorded since treatment started, or the appearance of 1 or more new lesions.

Time frame: Best tumor response assessed every 6 weeks by investigator during treatment up to 5 months after randomization of the first patient.

Population: All randomized subjects (the intent to treat (ITT) population) were included in the analysis.

HRQoL was assessed with the Functional Assessment of Cancer Therapy-Lung (FACT-L) questionnaire, a validated instrument for determining lung cancer HRQoL. The 36-item questionnaire includes 4 domains: Physical, functional, emotional, and social/family well-being, and a lung cancer-specific subscale. The FACT-L total score ranges from 1 to 136. Lower scores demonstrate impaired HRQoL.

Time frame: Change from baseline of HRQoL score assessed (at treatment Cycle 3 and Cycles 5 [21 days per cycle]) up to 5 months after randomization of the first patient.

Population: Of the 91 randomized subjects in the ITT population, 88 completed the FACT-L at baseline. Since more than half of the subjects received only 1 or 2 cycles before the trial was stopped, the number of subjects who completed the questionnaire after the first cycles was very low, making the results difficult to interpret.

The LCS is a validated instrument for determining treatment impact on lung symptoms. The LCS consists of 7 questions with 5 responses ranging from not at all to very much. The LCS total score ranges from 0 to 28. Lower scores reflect greater lung cancer symptoms.

Time frame: Change from baseline of LCS score assessed at each treatment cycle starting with Cycle 2 (Cycles 2, 3, 4, 5, 6, 7; 21 days per cycle) up to 5 months after randomization of the first patient.

Population: Of the 91 randomized subjects in the ITT population, 90 completed the LCS at baseline. Since more than half of the subjects received only 1 or 2 cycles before the trial was stopped, the response rate (number of evaluable subjects completing the questionnaire) decreased from cycle to cycle and makes the results hard to interpret.

Duration of response (PR or better) was defined as the time from the first documented objective PR or CR, whichever was noted earlier, to disease progression or death (if death occurred before progression was documented). Since only 4 subjects had a response, the duration of response was not calculated.

Time frame: Time from first documented objective response (complete response or partial response) to disease progression or death, or to last tumor assessment if censored, up to 5 months after randomization of the first patient.

Population: All subjects that showed a response. Since only 4 subjects had a response, the data were not analyzed.

Overall survival is the number of days from the date of randomization to the date of death due to any cause. Subjects alive at the time of analysis were censored at their last date of follow-up. Since the study was terminated early and 89% of subjects' data were censored, only the number of subjects who Failed (died) or were Censored is reported, not the usual measure number of days.

Time frame: Up to 5 months after randomization of the first patient

Population: All randomized subjects (the intent to treat (ITT) population) were included in the analysis. Since 89% of subjects were censored, OS could not be calculated. The number of subjects who Failed (died) or were Censored are reported.
