Progressive Disease was defined as at least a 20 percent (%) increase in the sum of the Longest Diameter (LD) of target lesions, taking as reference the smallest sum LD recorded since the treatment started or the appearance of one or more new lesions. The primary analysis of PFS used objective progression (RECIST) plus clinical progression (based on relevant clinical findings - if any). A further assessment of PFS was made on objective (radiological) progression. If clinical progression was diagnosed first, the participant was censored at the date of the last tumor assessment, where non-progression was documented.","groups":[{"description":"Participants received either pemetrexed 500 mg/m\\^2 every 21 days until disease progression, unacceptable toxicity or death or docetaxel 75 mg/m\\^2 every 3 weeks until disease progression, unacceptable toxicity or death. Choice of comparator was left to the discretion of the investigator in countries where both treatments are registered to use and are commercially available for second line use (otherwise, docetaxel was administered), assigning the participant to either comparator depending upon the medical needs of the participant.
