*Of note, in the process of data cleaning of a subsequent Part B data cut, baseline data of four patients were set to missing as their assessment had taken place after treatment initiation. For the present analysis, however, it was deemed irrelevant that treatment had already started, as the psychometric properties of the FACT-M should not be influenced by assessment time point. Hence, these patients are included in the psychometric analyses, explaining discrepancies between the sample size reported herein and the sample size used for the analyses of HRQoL outcomes over time where n = 98 patients (instead of n = 102) are included in PAS of the FACT-M
