Assessments and Outcomes Data and patient-reported outcomes were recorded every four weeks during clinic appointments. Clinical assessments, biologic measurements, and full tumor imaging had been performed at screening; subsequent imaging was performed during week 5 and week 9 and every eight weeks thereafter, whenever progression was suspected, and by the end of treatment or withdrawal from the study. Compliance and protection were assessed every four weeks and at the end of treatment. The primary end point was progression-free survival, defined as the right period from randomization to the initial proof progression or loss of life from any cause.
