Small Cell Lung Cancer
Conditions
Brief summary
This study is a Phase 3, global, multi-center, open-label study of patients with extensive-stage small cell lung cancer. Eligible patients will be randomly assigned to receive either pemetrexed plus carboplatin or etoposide plus carboplatin. It is anticipated that pemetrexed plus carboplatin will offer similar survival benefits as compared to etoposide plus carboplatin.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Overall Survival | baseline to date of death from any cause (up to 19.6 months) | Overall survival is the duration from enrollment to death. For patients who are alive, overall survival is censored at the last contact. |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Overall Survival (Subgroups) | baseline to date of death from any cause (up to 19.6 months) | The effects of individual baseline factors (sex, race, Eastern Cooperative Oncology Group (ECOG) performance, region, lactate dehydrogenase (LDH), age, number of metastatic sites, and history of brain metastases) on overall survival are reported. For two subgroups - LDH\<=upper limit of normal and brain metastases=yes, the upper limits of the 95% confidence interval were not calculable for the etoposide+carboplatin group - instead the number of participants in these two subgroups are presented as a post-hoc outcome measure. |
| Progression Free Survival | baseline to measured progressive disease (up to 14.7 months) | The period from study entry until disease progression, death or date of last contact. |
| Change From Baseline to Each Cycle in Functional Assessment of Cancer Therapy - Lung (FACT-L) | baseline and 6 cycles (21-day cycles) | FACT-L measures following domains of health-related quality of life (HR-QL): physical well-being, social/family well-being, emotional well-being, functional well-being, and additional concerns of lung cancer. Total scores range from 0 to 136, with higher scores representing better HR-QL. A clinically meaningful change is considered to be 5 points. |
| Overall Survival (Subgroups: LDH<=Upper Limit of Normal and History of Brain Metastases=Yes) | baseline to date of death due to any cause (up to 19.6 months) | The effects of individual baseline factors (lactate dehydrogenase (LDH) and history of brain metastases) on overall survival are reported. The Upper Limits of the 95% Confidence Intervals were not calculable for these factors in the Etoposide+Carboplatin group. The number of participants in these subgroup are instead presented as a Post-Hoc Outcome Measure. |

Overall Survival (Subgroups)
The effects of individual baseline factors (sex, race, Eastern Cooperative Oncology Group (ECOG) performance, region, lactate dehydrogenase (LDH), age, number of metastatic sites, and history of brain metastases) on overall survival are reported. For two subgroups - LDH\<=upper limit of normal and brain metastases=yes, the upper limits of the 95% confidence interval were not calculable for the etoposide+carboplatin group - instead the number of participants in these two subgroups are presented as a post-hoc outcome measure.

Overall Survival (Subgroups: LDH<=Upper Limit of Normal and History of Brain Metastases=Yes)
The effects of individual baseline factors (lactate dehydrogenase (LDH) and history of brain metastases) on overall survival are reported. The Upper Limits of the 95% Confidence Intervals were not calculable for these factors in the Etoposide+Carboplatin group. The number of participants in these subgroup are instead presented as a Post-Hoc Outcome Measure.
Time frame: baseline to date of death due to any cause (up to 19.6 months)
Population: The upper limit of the 95% Confidence Intervals (CI) were not calculable for these two subgroups in the etoposide+carboplatin group so medians and lower limits of the 95% CI are not presented. A post-hoc outcome measure table provides the number of participants in each subgroup.
Progression Free Survival
The period from study entry until disease progression, death or date of last contact.
Time frame: baseline to measured progressive disease (up to 14.7 months)
Population: All randomized participants. Number of participants censored: 113 in Pemetrexed+Carboplatin; 150 in Etoposide+Carboplatin.

Population: Number of randomized participants.
