Dataset from A Randomized Phase 3 Study of Two Doses of Alimta in Patients With Locally Advanced or Metastatic Non-Small Cell Lung Cancer Who Have Failed a Prior Platinum-Containing Chemotherapy

The purposes of this study are to determine: - the safety of pemetrexed and any side effects that might be associated with it - how much pemetrexed should be given to patients. It is possible that information collected during this study will be analyzed by the Sponsor in the future to evaluate pemetrexed for other possible uses or for other medical or scientific purposes other than those currently proposed. Although pemetrexed has been shown to be effective in some patients with non-small-cell lung cancer, pemetrexed might not have beneficial effects for all patients.
