Reporting Groups
  Description
Ipilimumab/Placebo + Paclitaxil/Carboplatin (Concurrent) During induction, participants received up to 6 doses of blinded ipilimumab with paclitaxel/carboplatin on a 3-week schedule. The initial 4 doses consisted of active ipilimumab with paclitaxel/carboplatin, and the last 2 doses consisted of placebo ipilimumab with paclitaxel/carboplatin. Ipilimumab, 10 mg/kg, was administered intravenously (IV) as a single dose over 90 minutes. Participants who did not progress and did not experience intolerable toxicity during the treatment phase were allowed to continue in the maintenance phase, receiving additional (blinded) ipilimumab at a dose of 10 mg/kg administered IV over 90 minutes every 12 weeks starting 24 weeks after the first dose until progressive disease (PD), drug intolerance, withdrawal of consent, pregnancy, death, loss to follow up, or study closure.
Ipilimumab + Paclitaxel/Carboplatin (Sequential) During induction, participants received up to 6 doses of blinded ipilimumab with paclitaxel/carboplatin on a 3-week schedule. The initial 2 doses consisted placebo ipilimumab with paclitaxel/carboplatin followed by 4 doses of active ipilimumab with paclitaxel/carboplatin. Ipilimumab, 10 mg/kg, was administered IV as a single dose over 90 minutes. Participants who did not progress and did not experience intolerable toxicity during the treatment phase were allowed to continue in the maintenance phase, receiving additional (blinded) ipilimumab at a dose of 10 mg/kg administered IV over 90 minutes every 12 weeks starting 24 weeks after the first dose until PD, drug intolerance, withdrawal of consent, pregnancy, death, loss to follow up, or study closure.
Placebo + Paclitaxel/Carboplatin During induction, participants received up to 6 doses of placebo ipilimumab with paclitaxel/carboplatin every 3 weeks. Matched placebo for ipilimumab was administered as a single dose IV over 90 minutes every 3 weeks (up to 6 doses) as part of induction. Participants who did not progress or experience intolerable toxicity during the treatment phase could continue in the maintenance phase, receiving maintenance placebo administered IV over 90 minutes every 12 weeks starting 24 weeks after the first dose.

[3] NSCLC=nonsmall-cell lung cancer; SCLC=small-cell lung cancer. Staging of NSCLC is based on the findings of several clinical tests, including magnetic resonance imaging scans and fine needle biopsy. Stages range from 1 (best prognosis) to IV (worst prognosis). Stage I cancer is confined to the lung. Stages II and III cancers are locally advanced. Stage IV cancer has spread outside the lung to other organs. SCLC is staged using a 2-tiered system: Limited stage SCLC is confined to its area of origin in the lung and lumph nodes. Extensive-stage SCLC has spread beyond the lung to other organs.

  Description
Ipilimumab/Placebo + Paclitaxil/Carboplatin (Concurrent) During induction, participants received up to 6 doses of blinded ipilimumab with paclitaxel/carboplatin (concurrent). The initial 4 doses consisted of active ipilimumab with paclitaxel/carboplatin, and the last 2 doses consisted of placebo ipilimumab with paclitaxel/carboplatin. Ipilimumab, 10 mg/kg, was administered intravenously (IV) as a single dose over 90 minutes every 3 weeks as part of induction. Participants could also receive additional maintenance ipilimumab at a dose of 10 mg/kg administered IV over 90 minutes every 12 weeks starting 24 weeks after the first dose.

The initial 2 doses consisted placebo ipilimumab with paclitaxel/carboplatin followed by 4 doses of active ipilimumab with paclitaxel/carboplatin. Ipilimumab, 10 mg/kg, was administered IV as a single dose over 90 minutes every 3 weeks as part of induction. Participants could also receive additional maintenance ipilimumab at a dose of 10 mg/kg administered IV over 90 minutes every 12 weeks starting 24 weeks after the first dose.
Placebo + Paclitaxel/Carboplatin During induction, participants received up to 6 doses of placebo ipilimumab with paclitaxel/carboplatin every 3 weeks. Matched placebo for ipilimumab was administered as a single dose IV over 90 minutes every 3 weeks (up to 6 doses) as part of induction. Participants who did not progress or experience intolerable toxicity during the treatment phase could continue in the maintenance phase, receiving maintenance placebo administered IV over 90 minutes every 12 weeks starting 24 weeks after the first dose.
