Groups2
Neither group, or both, names a comparator, so the groups keep ClinicalTrials.gov's order.
| Group | Title | Description | With the outcome | Analysed | ClinicalTrials.gov code |
|---|---|---|---|---|---|
| Group 1 | Crizotinib | Crizotinib capsules, 250 mg twice daily (BID), were administered orally at approximately the same time each day on a continuous daily dosing schedule. Each treatment cycle was defined as 21 days. Participants could continue crizotinib treatment beyond the time of RECIST defined Progressive Disease (PD), as determined by independent radiology review (IRR), at the discretion of the investigator if the participant was perceived to be experiencing clinical benefit. The maximum duration of crizotinib treatment was 324.4 weeks. | 62 | 104 | EG000 |
| Group 2 | Chemotherapy | Standard doses of chemotherapy were administered by intravenous (IV) infusion every 3 weeks for a maximum of 6 cycles. Pemetrexed (500 mg/m2) was administered over 10 minutes or according to institutional administration timing; cisplatin (75 mg/m2) was administered after adequate hydration beginning approximately 30 minutes after the end of the pemetrexed infusion and carboplatin was administered on Day 1 of a 21-day cycle at a dose calculated to produce an area under the concentration time curve \[AUC\] of 5 or 6 mg\*min/mL, beginning approximately 30 minutes after end of pemetrexed infusion. The maximum duration of chemotherapy treatment was 24.1 weeks. | 61 | 101 | EG001 |
